2017 CHEVROLET VOLT Fuel/propulsion System Problems

Experiencing intermittent propulsion system failure with multiple simultaneous warning messages on 2017 Chevrolet Volt at approximately 59,000 miles. WARNINGS DISPLAYED: - "Propulsion Power Reduced" message - "Check Tire Pressure Monitoring System" (false alert - all tires properly inflated and recently replaced) - Multiple dashboard warning lights including exclamation point indicators - Vehicle exhibits abnormal driving characteristics PATTERN: Issue occurs intermittently while driving. Vehicle can be restarted and may operate normally afterward, then fault returns unpredictably. SAFETY CONCERN: This matches documented Battery Energy Control Module (BECM) failure pattern referenced in GM investigation N232432680/PE23022 and Customer Satisfaction Program 17228 recall N172096420 for reduced propulsion power in 2016-2018 Volts. Review of owner complaints shows other 2017 Volt owners experiencing sudden complete loss of propulsion while driving at highway speeds, creating dangerous situations requiring evasive action by other drivers. RISK: Loss of propulsion power while driving with dependent passengers creates serious crash risk. Vehicle is used for daily transportation of minor children. REQUEST: Vehicle exhibits known defect pattern but manufacturer has not extended recall coverage. Request investigation into whether recall should be expanded to cover additional affected vehicles.

The BECM (Battery Energy Control Module) failed. The vehicle illuminated the MIL and the driver display to show a "Reduced power". When restarted, the display showed "shift to park", which I did several times. After a couple of restarts it displayed the "Reduced power" message, but would not go into drive. THE MIL was illuminated the entire time. Through numerous key cycles I got the VIN operable and took it to the dealer for repair. The BECM part is at the dealer or on its way back to GM as a core return. While this occurred while I was leaving my garage, it could have occurred in traffic, which would put me or others at risk. The problem was investigated by my local dealer (Currie Chevrolet in Forest Park, IL) and it was determined to be both a bad Battery Energy Control Module (BECM) and a bad shifter assembly. The shifter had been replaced (or repaired?) for an earlier Shift to Park failure per TSB 23-NA-119. The dealer kept the BECM as a core. I have pictures of the core. The dealer or GM should have that core. The above described warning lamps and messages and systems first appeared at the time of the event that lead me to take it other dealer ASAP. Note the condition and model year is described in GM special coverage letter "N232432680 Battery Energy Control Module Malfunction". NHTSA investigation PE23022 lead to this coverage letter. Per GM, while my vehicle experienced the conditions and is in the model year coverage of the letter, its VIN is not covered. I think NHTSA should re-open the investigation and consider a recall. There could be other VINS susceptible this failure condition. There could be operators of those VINs who cannot afford the expense (~$3000 or more) or downtime of the repair, and will keep operating the vehicle, putting people at risk again. If a recall is not supportable, I'd request that the VIN list be expanded to cover all possible defective BECMs.

On 10/14, I was driving the car to my job, when the car suddenly switched from its electric battery power to its internal combustion engine. The vehicle's information screen only showed that the battery was unavailable. I was able to operate the car on only the internal combustion engine to arrive at work. However, when I went to leave several hours later, the car would not start. The car was towed to a dealership and apparently repaired after about a week. However, the repair, a software reset, did not fixt the underlying issues, and on 10/27, after having the car for five days, the car again failed on my way to work, displaying a "Shift to Park" message and not starting. I towed the car to the same dealership, and they had it until 11/04. I recovered my car and drove it again to work that same day, but the car failed again due to the dealership not correctly diagnosing the issue, which appears to be the BECM, a failure related to bulletin N232432680. Due to this issue, I was left stranded on a busy highway for several hours on multiple occasions, and have not have a working vehicle since 10/14, meaning I have had to call off of work on multiple days, losing non-trivial amounts of income and undue economic hardship, due to this issue. Neither the dealership nor General Motors have offered any kind of help or support, and have generally attempted to avoid responding to my repeated phonecalls. Prior to this issue, there were no warnings or symptoms that I observed.

I was driving in stop and go traffic on a relatively busy road when I was cut off. I braked hard to avoid a collision. Immediately afterwards, the car would not respond to the accelerator and would not go forward. I was in the middle of the road and the car would not respond. It could have caused an accident. I put the car into park and then back into drive and it seemed to work again. But I am now worried about the car.

I am reporting a series of safety concerns regarding my 2017 Chevy Volt, which have persisted despite multiple attempts to address them with the dealership. These issues pose significant risks to my safety and that of others on the road. On January 18th, 2024, I brought my vehicle to the dealer after experiencing reduced propulsion power while driving on the highway, coupled with the illumination of the check engine light. The mechanic performed a quick inspection and used a GM scan tool to diagnose the issue, revealing the code P1E00 for the Hybrid Powertrain Control Module 2, which was cleared without a thorough investigation. I was advised to return if the issue reoccurred. Despite the reset, the problem persisted, and on February 9th, 2024, I scheduled another appointment due to my Chevy Volt's High Voltage battery charging only to 65% capacity despite indicating a full charge. Subsequently, on February 11th, 2024, the check engine light illuminated again, and on February 12th, 2024 and again on November 25th, 2025, while driving to work, both times I experienced a loss of propulsion power on the highway, placing my safety at risk and lost all power in a traveling lane of traffic. These ongoing issues with propulsion power and the high-voltage battery charging system are not only inconvenient but also potentially dangerous. Despite multiple visits to the dealership and attempts to diagnose and resolve the problem, it persists, indicating a systemic issue that requires immediate attention. The reduced propulsion power while driving on the highway, coupled with the illuminationI urge the National Highway Traffic Safety Administration (NHTSA) to investigate this matter thoroughly to ensure the safety of Chevy Volt drivers and passengers. It is imperative that General Motors addresses these issues promptly and implements appropriate measures to prevent further incidents.

Vehicle propulsion system failed. According to Chevy dealer the Battery Energy Control Module and A/T Control Park Switch and harness failed. Warning lights came on when the failure happened. Failure happened just past the extended 150k mile warranty. But car in only 8 years old.

My EGR system caused a check engine light. P0401 This is an extremely well documented issue on Gen2 Volts, especially 2017 models. Simply searching "EGR" on the Volt subreddit or forums returns hundreds of related threads. This issue can lead to a clogged EGR valve, causing further damage. A temporary resolution is unplugging the EGR valve, which i have not yet done. But this leaves the CEL illuminated, and without daily scanner, I wouls not know if other issues arise, causing a significant safety hazard.

EGR Valve failed in this vehicle <55,000 miles. The EGR valve has an electronic component that, when fails, can cause the car to shut down by blowing the "walk home" fuse. This is a safety issue. This is a well documented problem (internet) and Chevrolet refuses to fix it, leaving the owners with an expensive replacement quoted at $3900 (Sept 2025). Recommend that it be covered by the emissions warranty, which was recently extended to 150,000 miles and 8 years for other problematic emissions components. An electric vehicle that cannot be driven because an EGR valve is faulty - it's a joke.

Check engine light came on car was able to start but the cluster started reading the battery being full with a charge. And was having trouble starting. Fast forward a day I get a propulsion system reduced warning on the dash as I’m entering the highway and the car fails to stay on I’m able to pull it to the shoulder and I cannot get the car to start. Get towed home throw it on the charger and the dash says unable to charge. swap the 12v (checked it and it died) thinking that might fix the problem since the car was able to power on but not start. To no avail through my code reader and code p1e00 code. Took it to my local dealer and was told id need replace the becm… and was quoted 33xx for the repair. Had any of this happened while I was on the freeway I might not have been able to make it to the shoulder potentially putting myself and others on the road and a possibly fatal situation.

Propulsion power reduced and check engine light came on my 2017 Chevy volt - been happening a few times now the last week

I was driving my car from Houston to Dallas when I got the "reduced propulsion" message and a check engine light. When I first saw the reduced propulsion issue I thought it might be related to the BECM issue again since I had already experienced that problem before. In the last few minutes of my trip the AC started to get hot and when I checked the coolant temperature I noticed it was around 240 - 255 F. I hadn't noticed it since there was no warning light for high temperature which I am used to with other cars. I'm not sure of the full extent of the issues yet, but I know for certain that the EGR valve has failed completely at about 71,500 miles. This is with very few miles on the actual ICE. I typically only use the ICE for a few hundred miles of driving each year. Fortunately for me, even though the CEL came on for the reduced propulsion I was able to reach my destination. However, when I went to leave, the car left me stranded as the ICE would shut down after a few minutes of running. The propulsion system is reduced and the engine becomes unavailable. Only the battery power will allow the car to drive. The F3 fuse in the EGR circuit blows if the engine is activated, and has happened multiple times already confirming the EGR issue. I have additional check engine lights that are a result of the EGR failure to circulate coolant properly. Below is a list of all the CEL codes that were pulled: P06DB P0030 P0031 P0403 P0405 P0443 P0458 P0489 P0597 P0598 P06DA P0AC4 P0135 P0AC4 P16E0 Looking into this issue I found that this is an one of the most common failures in the Chevy Volts but is no longer covered under the vehicle warranty and no bulletins posted for an extended warranty other than the BECM failure. This failure is so prevalent that I am surprised it is not.

While driving approximately 65 MPH on an interstate highway, the vehicle's check engine light illuminated. Very shortly after, the dashboard screen displayed the message "propulsion power reduced," and the internal combustion engine turned on. The vehicle's power was significantly reduced, almost causing an accident when another car started merging without checking their blind spot, forcing me into the left lane in front of a third vehicle that had to brake sharply to allow me to accelerate to keep up with traffic in that lane. Upon scanning the vehicle with an OBDII reader, codes P1E00, P1F06, U2603, U2604, U2605, U2606, U2617, and U2618 were present. Together, these codes indicate an issue with the Battery Energy Control Module (BECM). The vehicle is currently at a Chevrolet dealer, awaiting replacement of the BECM under the applicable warranty extension.

Portion message car stalled on hey

Driving on interstate doing 65 and suddenly warning pops up and car dies immediately. I was lucky to get over to the edge and not wreck or cause an accident. Found that the 12 volt battery was not being charged without warning until failure. Found a 15 amp fuse blown in the high voltage relay module.

I got a warning from my car a little over a week ago (around 6/1, unsure of exact date) that I needed to service the battery charging system, but then the check engine indicator light shut off and so did the warning light. The hybrid battery took a charge with no issues after that. Then, I left work the evening of 6/9 and drove home. On my way home, the check engine light came back on, followed by warnings that I needed to shift to park. Before I could pull over, my car stopped moving. Cars had to stop abruptly behind me and navigate around me into incoming traffic. I shifted to park, then tried to turn my car off and on again. I tried to switch between the gas engine and the battery, I tried to move my vehicle in any way. I couldn't get it into neutral to push it out of traffic. I turned on my hazard lights and a person came out from his house to assist in directing traffic away from my car for about an hour while I waited for a tow truck to arrive. The kind bystander who directed traffic and I were very concerned about a car accident happening due to my stopped vehicle. A police officer stopped by to check on us and try and get my vehicle into neutral but he was unable and said he was on his way to a 911 dispatch so he did not write a report of any kind that I could see. He told me the vehicle placement was not safe and I agreed with him. The tow truck came as he was leaving. The dealership I sent my car to said it is likely a short circuit in the 12v battery but I know the BECM in the Chevy Volt is known to cause similar behavior. Dealership refused to service the BECM when asked about it.

While driving the vehicle, the car shut down. Thankfully I was coming to a yield at a round about after exiting the Interstate. I was finally able to get it to restart and proceeded on my way. If this had happened on the Interstate myself, and other drivers would be at risk due to unassisted steering and braking. I also have experienced intermittent periods of "Reduction of Power" while on the interstate and other 55MPH plus highways. This presents a hazard to myself and other drivers as well. These issues ARE covered for similar vehicles under Special Warranty Coverage N232432680 as required by NHTSA on March 6, 2024. My vehicle also exhibits all of the primary symptoms described in that coverage, but GM claims that my vehicle is NOT covered. CEL is on. Can't charge condition Reduced power No start condition

There was a recall for the HPCM2 where the propulsion power reduced warning would come on whenever the car's cell battery was depleted. This happened with my car and there were several times it slowed on the freeway and on exit ramps as I tried to safely get my car off the road. It first happened on 4/13/25. I took my car to a regular mechanic who charged me 3k of repairs on basic maintenance, new tires, etc but were unable to fix this issue. They advised it was a manufacturer issue and to go to a hybrid specialist or a dealership. I called a hybrid specialist who found the faulty code and advised the same. I took my car to Felix Chevrolet (3330 S. Figueroa St. LA, CA 90007) and they offered to do many maintenance service items that I had done earlier this week in an attempt to fix the HPCM2 software bug. After I told them that the maintenance items were complete, they called me back an hour later to tell me I needed other maintenance repairs that are less common. When I gave them the description of the recall and re-explained this is identical to my car's symptoms and that this manufacturing issue may have affected other vehicles like mine that were outside of the recall batch, they told me it was impossible to apply this diagnosis as long as my VIN number was outside of the recall batch. Can you please add my VIN to this recall or have my car reviewed by someone who can debug the software?

Unknown My car has been accelerating and decelerating on it’s own while I’m driving.I got it checked with Fix Finder and states that my EGR Valve and ABS System failed. I brought it to a mechanic for a repair and I was told that the valve was unplugged so they plugged it back in and cleaned it , and said that everything was fine it said it might also be the cause of the failed ABS System but everything looks fine. After I got it fixed, it’s doing the same again and it’s worse this time. The car is accelerating on it’s own faster than what it did but the dashboard is saying 0mph. I was driving in the highway when it happened and it’s scary so I had to pull over.

P0401 code caused the car to say “propulsion power is reduced”. I was on the highway and had to pull off to find a safe place.

Vehicle lost all motive power while driving on the Highway. Vehicle is part of GM Special Coverage program number N232432680 for BECM issues up to 150,000 miles. Vehicale currently has 109350 miles. Failure on highway while driving is unacceptable and should have been a recall instead of special warranty. GM support is not helpful with service or transportation (one month out for service only at select locations). Vehicle will not restart and had to be pushed from the roadway.

Battery Energy Control Module Failure There is an existing NTHSB issue related: N232432680 I was told my VIN is not included in this issue, so the failure is not covered under warranty by GM. That said, the same failure and symptoms occurred (prompt multiple battery cell failures leading to electric drive inoperable). I was told, by others with Volt's who had same issue, that my VIN was not included because it was under a PZEV warranty since it was originally sold in California. I do not live in California, so the extended 150K mile / 15 year warranty does not apply to me. Car is currently at the dealership, and I was told the same repairs as in this NTHSB issue are needed at a price of > $2,500. As such, I am asking to have my VIN added to this issue for reimbursement.

EGR Failed, which blew out the walk home fuse. THAT IS A SAFETY ISSUE. GM DISCOUNTUNUED VOLTS AND THE EGR VALUE IS NOT AVAILABLE WORLDWIDE.

My Chevy Volt went into Reduced Propulsion System Power Mode, the Engine light came on and the vehicle stalled while sitting at a traffic light on [XXX] at [XXX] in Tyler Texas. Checking the computer and the complaints online I found that my 15 AMP #03 fuse (No Walk Home) had blown. I replaced the fuse and the next day on [XXX] the same thing happened again after driving 30 miles. The vehicle stalled at an intersection outside of Tyler Texas. The EGR Valve is known to cause the fuse to blow, so I had no choice but to unplug the EGR Valve and replaced the fuse and has not blown the fuse since. This is BOTH a safety issue and an emissions issue, but the replacement part cannot be found anywhere to purchase anymore so I am having to drive this vehicle with this ongoing safety issue. Due to the nature of the EGR Valve blowing the fuse all the time and that it affects the safety of the vehicle a nationwide recall needs to be done on these vehicles to force GM to start making the part again. This is a dangerous flaw that will cause the vehicle to stall and create a safety hazard. This has been ongoing for quite some time with these Volts, and something needs to be done about it ASAP.

My car needs an Egr valve replacement and this is a known and common problem with this car and now they are trying to charge me outrageous prices for an issue that they know is defective. The becm , the Egr valve, and the shift to park. need to be recognized as recalls

On December 2023 the vehicle lost power and lost control while driving speed limit 55 Mph followed by check engine light associated codes due to known issue with BCEM controller failing. June 2024 Vehicle experienced the same issue with duplicate check engine codes associated with prior issue. Dealer states the vehicle has a bad battery pack and has been there for over 8 months. Vehicle has a BECM warranty due to a law suite filed and also has a battery pack warranty from GM that was extended for 150,000 miles or 10 years.

The EGR valve failed. This caused the vehicle to have insufficient propulsion while driving. The dealer has confirmed the EGR valve is the problem. The vehicle is at the dealership. The check engine light came on. The dealer is now stating the replacement EGR valve is a $4000 part because GM stopped making the part when they discontinued the Volt. An EGR valve should cost $250-$400 not $4000. The current trade-in value of my vehicle is only $7000. I cannot get my vehicle fixed due to the cost and the vehicle is too dangerous to drive due to the power loss issues.

The EGR Valve and EGR Cooler went out on the vehicle while driving on the highway, causing my propolsion power to decrease or rendered unusable. This also caused inconsistent engine pressure and caused my engine to overheat, having to pull over multiple times while driving. The problem has been diagnosed by a Chevorlet certified repair center. There were no warning lamps or messages until the problem began abrubtly while driving.

I was driving effortlessly down [XXX] between san francisco and santa cruz when suddenly i seemed to be losing power. Pressing the accelerator/gas pedal was not obtaining the usual result and I was going slower and slower by what felt like the second. I also noticed that it switched to gas although it said there were around 12 miles on the EV battery which was a sign that something was wrong. Fortunately there was a break and traffic was going at a speed which allowed me to make it across three lanes of traffic in just enough time for an alert posted on my dash saying something about loss of propulsion (not sure what it said exactly, because, i was driving!) and i coasted onto the shoulder, but barely. By that time it indicated that there were zero miles on the EV battery. (2 weeks prior I had been unable to start the parked car. I had the 12V battery replaced as the local mechanic where it was towed thought that that might be the cause.) I turned the car off and back on and when I tried to shift to D or R the dash stated "Return to P" AAA made us a priority tow as we were on a major thoroughfare. We were at risk, but thankfully we were relatively safe. I called GM to say that it seemed that the EV battery had died suddenly. I was advised to bring it to the dealer. I called the dealer and they quoted me the cost of replacing the EV battery. They mentioned nothing of National Highway Traffic Safety Administration investigation into the model year 2016 through 2019 Chevrolet Volt amid complaints about the hybrid’s battery energy control module, or BECM, some of the complaints indicating that drivers had little to no warning before the car lost operating power or entered reduced power mode, which was exactly what had happened to me. Nor did they mention a letter I discovered on line dated March 6,2024 re:Battery Energy Control Module Malfunction, and stating that they would be contacting customers. I was never contacted.

I was driving at about 50mph all of a sudden I got a propulsion error and my car stopped working it had no power! People had to swerve around me and I was almost hit. My car would not drive I shut it off and back on multiple times. Finally it started but would not go above 25 it was so scary. I went to the dealership they said it’s known issue since 2016 and that my miles were too high so it would not be covered to fix the total amount it almost 3,000 this seems unfair that Chevy would continue to sell a vehicle knowing it had issues with a energy control module and not fix it for free. Especially when you could be killed while driving it!!

N232432680 / PE23022 On some 2016-2018 model year Chevrolet Volt vehicles, a malfunction involving the battery energy control module (BECM) may cause a reduced power mode, a no start condition, or a no charge condition. The above safety issue required an extended warranty recall for *all* 2016-2018 Chevrolet Volts due to a known issue with failing battery energy control modules (BECM). The warranty was not extended to vehicles sold in CARB states, as the Partial Zero Emissions Vehicle (PZEV) warranty is the same as the extended warranty granted by the NHTSA investigation which resulted in the extended warranty noted above. (N232432680) However, it GM's practice to decline warranty coverage for a CARB vehicle with the PZEV warranty if it is not longer registered in a CARB state, thereby skirting around the special coverage from the NHTSA investigation. This is a circumvention of the findings by the NHTSA and the safety of motorists.

Propulsion Power Reduced and car had trouble breaking and would stall for a moment. Will not let me use the EV range even though the ev battery is at fully charge.

On [XXX] my 2017 Chevy Volt was having propulsion issues, and later would not start at all. This was not the first instance of propulsion issues, fortunately I was able to pull the vehicle into parking lots. The vehicle was towed to Midway Chevrolet, 2323 W Bell Road, Phoenix, AZ 85023. On Friday [XXX] the dealership called me to let me know the vehicle was ready for pickup. After my arrival at Midway the car was driven one last time and must have experienced trouble, so it was checked out. Midway then informed me that one of the 32 Battery Energy Control Module (BECM) was not producing enough voltage to propel the vehicle and not drivable. Midway ordered the replacement BECM and when I inquired several days later I was told the BECM was on backorder and they hoped to have the BECM in September 2024. In September I was told that part might be available in December 2024. I have checked with the GMPARTSCENTER and other component distributers and told the part was on national back order. Although I was fortunate the vehicle didn't die completely while I was driving it, it was certainly a concern. The vehicle has now been at Midway for 6 months and the lack of availability of the replacement BECM is a concern. What if another section of the battery has a voltage issue once I get the vehicle back? I will be placed in an unsafe situation and facing months of having the vehicle at the dealership waiting on parts.

Power surge I hit the gas to cross the highway and lack of power then got home the next morning started the car and it started serging in the driveway then it shut down altogether.

Problems with EGR valves still in defects, and engine gaz motor loose power. GM don’t have enough parts to resolve them.

This is a safety issue for Chevy Volt. After seven years of good operation, our 2017 Chevrolet Volt stopped running in traffic while we were driving on [XXX]. The Check Engine Light was on, and "Reduced Propulsion" Message on dashboard panel. We brought it to the dealer from whom we purchased the vehicle. Tech Report paraphrased, Customer states CK Engine Light is on and "Reduced Propulsion" Message on dash Fault Codes: P0030, P0031, P0054, P0135, P0403, P0405, P0443, P0458, P0489, P0597, P0598, P06DA, P06DB Found fuse [F03] blown for EGR valve Likely EGR Valve sticking and causing fuse to blow. The technician stated the Exhaust Gas Recirculation (EGR) Valve is defective, and needs to be replaced. Replacements are scarce, on backorder, and can be many weeks or months to wait for a part. Many report their Volt unusable, sitting idle, waiting for EGR replacement. EGR valve replacement cost is quoted as $2800, which is quite expensive for a valve replacement. This has been happening in recent time to many Volt owners. There are many reports in online forums and no the GM forum website. [XXX] There has been no diligence, interest, nor cooperation from GM. The cost of replacing the defective valve is usurious, outrageous, indefensible. This is a problem well known by GM, who neglects their obligation to contact owners of a safety hazard inherent in their vehicles. The Volt's EGR valve can cause the car to shut down by blowing the "walk home" [F03] fuse, which was our experience. This is a safety issue.

My car stopped all of a sudden and lost power while my wife was driving. She could've been in a major accident since the car lost power. This has happened a few times in the past. Luckily she wasn't on the freeway or she could've been rear ended at highway speeds. There were warning lamps that said check engine and "Lost Propulsion". This should be looked at closely as my safety as well as the safety of others was at risk. VERY DANGEROUS SITUATION! I had my car towed to the nearest auto repair shop where it is being looked at.

The vehicle tells me to "stop and shift to park" while I am driving, and power was lost to accessories such as the climate control. Since the EGR was identified as the cause of the problem, the car remains on "Propulsion Power Reduced" mode. The EGR has been backordered for months, if not years, and aftermarket third-party EGR valves are not readily available either. However, there is no recall, and this is clearly a common problem on these vehicles as attested on GM-Volt forums. The EGR failed about one year ago, but now the message on reduced propulsion power is presented every time I start the vehicle.

On November 8, I was on a 5 hour drive and after 4 hours while driving on the gas engine since the 43 mile electric range was already depleted, a warning suddenly appeared on the dashboard screen - Shift to Park, something about reduced propulsion and the check engine light came on. I was driving 55 mph on a highway and immediately had no propulsion whatsoever. Tried to pull over and barely got to the edge of the highway with cars and trucks speeding behind me and then around me. On the roadside, the car would turn on and off and I could change gears with the shifter, but no matter what I did the propulsion to move the car would not work. The car had to be towed to the nearest dealership for repairs where it remains.

Was driving on highway when given error ""Propulsion Power Reduced." This resulted in less power available, which is a safety hazard. Then after a while of driving (on the highway) I received the error "Engine Not Available," which caused me to have to continue on electric only power. If I did not have any battery left in the traction battery, I would have had to maneuver to the shoulder. The error code revealed by a scan with the OBD device P0403 relates to a failed EGR valve. There are no replacement parts for this valve, according to GM, so future failure is likely.

Currently, two two issues are ongoing with my 2017 Chevrolet Volt Premier. I took my Volt to Epic Chevrolet in Sacramento, CA, on August 9, 2024, because the "Propulsion Power Is Reduced" warning and the "Service Park Assist System" warning came on with the "Check Engine" light. After diagnosis I was informed that the "EGR Valve" has failed; however, Chevrolet cannot procure the EGR Valve to repair my Volt and it is now October 14. I have been coordinating with Chevrolet Customer Assistance who continue to inform me that they are looking for the part but cannot provide it - apparently this part has been redesigned. This is the third time in 12 months that the Volt has been in for repair, all under warranty, for charging and propulsion related issues. On August 23, 2023, the Volt was in the shop for 15 days getting the "Battery Energy Control Module" replaced under warranty. On [XXX], one week after being repaired, my car would not start and had to be towed. That time the "Hybrid Battery Disconnect Relay Assembly" failed and was in the shop for 14 days, again repaired under warranty. This time, my car has been in the shop for 66 days waiting for an EGR Valve that, per Epic Chevrolet, is covered under warranty. It is unacceptable for Chevrolet to warranty its cars but not have the parts to perform the repair and let owners continue to pay loans on a car, insure a car, and have financial hardships for not having a car. I am not confident that, once fixed, something else will not go wrong. Plus, I was quoted $1,160 to fix the safety issue of the Parking Collision Warning.

Mil came on for egr malfunction. Part not available.

At least 4 times in the past 1.5 years, my car has given the message “propulsion power is reduced” at random times. Each time after receiving this message, the car engine begins making a loud noise and the acceleration is greatly reduced, forcing me to drive at a slower speed until the message goes away. The most recent time it happened, in Aug 2024, it was late at night in an area with little to no cell service and I was genuinely terrified the car would just shut down, as I knew this model has done the same to other Volt owners. Thankfully, I did make it home, but this is something that has happened more times than I’m comfortable with, and I fear the day it happens again and puts others at risk. It has not received any further inspection other than the yearly state inspection, which is up to date.

Automation-On 10.1.24 my car stopped working. It would turn on, but would not shift. It was also showing my EV was fully charged but the EV miles read 0. My husband came and plugged my car in and saw that when I turned the car on it read "shift to park" Also the codes from my OnStar app read "Lithium Ion Battery"- Issue found in High Voltage battery. "12 volt battery needs attention" 10.2.24 we called GM to report issues and referenced N232432680 (BCEM). We were informed that even though we can read diagnostic reports on OnStar it needed to be confirmed from a certified GM dealership that they could not confirm this is the warranty issue if they did not 1st had the certified dealership share their diagnostic report. Bergstrom shared it sounded like BECM that is under warranty. They continued to share it didnt look good and the VIN was not in the system to be covered. Shared the minimum amount we would pay was $440 for the 2 issues for labor/diagnostics.10.4.24 we called GM to file a report we were given a case manager to work our case. 10.8.24 received call from case manager shared no warranties seen on file. I asked for this to be documented and emailed to me, I was told she could not share this information other than this phone call. Bergstrom called saying the car was ready to pick up, cleared codes/no issues, drove 26 miles with no codes. Shared GM never seen/heard anything like this and had no advise/help to offer. Shared only charged for 1 hour of labor. Asked for trade in for car. Was given price $1,200 under trade in value. Cause due to car not safe, potential issues. No documentation shared, nothing to show issues, car is clean/cleared to drive they had no answer than my car was fine but was not able to give lowest amount for trade in due to issues

While driving on the highway there was sudden power loss with a message on the display stating "propulsion reduced" and had to pull over.

As I understand it, the EGR valve failed causing the car to shut down suddenly on the highway. Apparently by blowing the "walk home" fuse. The EGR valve has been unavailable from GM worldwide since Oct 2023 and there is no estimate when it will, if ever, be available.

Reduced propulsion message appears on the dash and car lost propulsion on the highway. The EGR blew a fuse and the car enters the walk home mode. This problem should be covered under warranty but my dealership says it is not covered. This issue causes the car not to be able to drive. Chevy is back ordered for the part and there is no estimate of when the part will be available. They apparently do not make the part anymore and there is no fix. Th EGR seems to have bad soldering and blows the fuse #3.

While driving on high-speed devided highways including stretches where traffic was 2-way (single lanes separated by concrete barrier during road maintenance) Chevy Volt indicated "reduced propulsion", and in 2 cases forced shut-down of electric and gas engine where the single-lane travel had cement barriers on both sides of the driving lane.In at least one case, the engine forced 30-40 mph travel until a break in the right-hand cement barrier was interrupted and I could get off the highway. In another case, the engine and fuel propulsion shut down but there was a breakdown lane on the right allowing traffic flow but exposing me to risk due to how close 65 mph traffic was passiing me. In each failure case, after turning off and re-starting the vehicle, the vehicle seemed to have re-set propulsion control and I could continue the trip at normal speed until another warning but not complete faillure occurred (both lanes being available so I could drive to an exit, turn off the ignition, restart and resume the travel). I believe the failure was in the BECM (Battery Energy Control Module) but the Chevrolet dealer identified an EGR failure that prevents their repair team from diagnosing the BECM. Whatever the failure was, it put me iin a very dangerous situation in at least 2 points in my 600 mile trip.

WHILE DRIVING, A WARNING CHIME SOUNDED AND A MESSAGE APPEARED SAYING "PROPULSION POWER REDUCED." THE CHECK ENGINE LIGHT ALSO APPEARED. THE CAR LOST POWER, WOULD ACCELERATE ONLY VERY SLOWLY, AND EVENTUALLY DIED ALONG A BUSY ROAD. AFTER A PERIOD, I WAS ABLE TO RESTART CAR AND DRIVE VERY SLOWLY TO DEALER. I WAS TOLD THAT THE PROBLEM WAS A FAULTY EGR VALVE, WHICH WAS BLOWING A FUSE AND WOULD DO SO AGAIN. DEALER WAS UNABLE TO FIND A REPLACEMENT VALVE ANYWHERE IN THE NATION. GM APPARENTLY IS NOT MANUFACTURING REPLACEMENTS FOR THIS COMPONENTS, AND FROM REPORTS FOUND ONLIINE, PLENTY OF OTHERS HAVE HAD THE SAME PROBLEM. THE TEMPORARY FIX IS TO DISCONNECT THE EGR VALVE, WHICH RESULTS IN INCREASED VEHICLE EMISSIONS. I WILL BE UNABLE TO PASS MY NEXT EMISSIONS TEST NEXT YEAR. THE SAFETY ISSUE IS THAT THE VEHICLE CAN QUIT RUNNING WITHOUT WARNING IN ANY SITUATION.

This car has a failed EGR valve which first became evident in March of 2024. There are no parts available, this in an emissions issue but the failure causes blown fuses which can cause the car to completely stop running which is a safety issue. Reduced propulsion is a symptom which is dangerous and this has been confirmed by three Chevy dealerships. I have had the EGR valve cleaned to the tune of $1200, have a deposit on a new valve which doesn't seem to exist for $850. There were no other messages before the failure. I am driving the car with the EGR valve disconnected, mostly on the battery power but no end is in sight to this problem.

Reduced propulsion power and check engine light. EGR valve failure per mechanic. Part has been on a global back order for 1.5 years. The car will not pass emissions testing and can blow a fuse that will make the car inoperable. The part is also costly at 2400.00 without labor costs. My car has 83,000 miles, is well-maintained and only 7 years old and now I can’t drive it or sell it.

Vehicle began exhibiting issues with BECM, reduced propulsion/limp home mode with range-extender activation. Car unexpectedly stopped running in the middle of the road, came to a complete stop and unable to move off road under car's propulsion.

Experienced severe engine failure while driving on the freeway, which cost to be in operable due to failure of EGR valve. This is a warranty repair however GM has part on backorder for over a year with no plan to fix. My car is now disabled and I have no other transportation.

EGR Valve issue. I have a 'reduced propulsion energy' notice on the dash. Unable to get repaired because there is no parts. This is a common problem with these Chevy vehicles. Emissions test won't pass

Egr valve failed. GM has this part in a national control status. Vehicle should be under warranty per the handbook but dealership is denting this. Dealer solution is to just disconnect the part and says it is safe to drive. Not comfortable with this since I have had this vehicle modified to allow myself who is handicapped the ability to drive it. Dealership wants prepayment of part before placing the order for it. Part is expensive and they have no idea how long they will be using my money before or if the part is available.

I was driving on a highway around 70 mph on cruise control, without warning a “propulsion power reduced” message came up with the check engine light turning on and the car stopped accelerating/let off of cruise control. Very dangerous when driving at speeds above 70mph. I took the Car to Chevy and they said it’s a EGR valve issue and that it would cost roughly $3,800 and the part is on massive back order. r Reading online, there’s many Volt drivers with the same issue and can’t get the part for months on (with some being offered a repurchase of the car from GM so the problem would go away) it seems like Chevy and or GM do not have sufficient parts to fix the massive amount of Volts having this specific problem and on top of that, this is the largest quote I’ve seen for this repair.

P1E00 error code resulted in the propulsion system being reduced and climate controls turned off. My wife, driving at the time in a thunderstorm, lost the ability to drive the speed of traffic and also her windshield completely fogging up where she could not see. She could have been killed in this scenario in a number of ways. Took it to the dealer where GM apparently has no spare parts available for months??? Parts at fault are related to the EGR valve and cooler. CEL light came on and off for a few days prior. Failed to be able to pull the error code because it would go off.

EGR valve failed while driving on the freeway. Loss power. Check engine light on. Propulsion power reduced. It is safety and emissions related.

The EGR (exhaust gas recirculation) valve has failed, which causes issues with the fuel propulsion system, can cause the cooling system to fail, and affects the emissions system. We are unable to obtain a replacement valve anywhere and have been on a waiting list at the dealership for months. The car is not safe to drive in this condition.

Without warning, my car stopped charging. Noticed it was at 0 miles despite charging it the night before. Believing I may have not properly connected the home cord (supplied by Chevy) to the car, I chalked it up to being my mistake and plugged in again the next night. Same result. 0 miles. Then it immediately started acting like a 12V battery failure with engine warning lights and then it just refused to start and/or charge and was dead in the water. I called AAA for a battery jump and they came. It got the car started, but the check engine light remained lit for two days and I primarily ran the car on its gas generator to hopefully charge it. Just last night, the check engine light went away. Despite having a partial charge, this morning 8/29, it registered 3 miles down from being higher. I just plugged in to my home outlet using the chevy cord, and again, it would not charge (no green light on dash indicating active charge and a message on the dash should "unable to charge". I suspect a Battery Energy Control Mondule (BECM) failure which seems to happen with this car. My 12V ACDELCO battery is relatively new (3 yrs) and not used heavily (given COVID).

My 2017 Chevrolet Volt started displaying an error message last week "reduced propulsion power". I set up an appointment at the dealership but had to continue driving in the meantime. The error message changed to "Engine Unavailable" and shortly therefore shut down completely. We had it towed to a dealership, who has informed us that the EGR valve and gasket need to be replaced, and are on indefinite backorder. This is clearly a safety issue as we need to be able to rely on the car not shutting down in the middle of driving. Now we are left without a car or a timeline for repair.

1st incident-While doing a U-Turn on an inclined road car suddenly sounded like it was going to die, no acceleration when I pressed on the gas pedal. Car almost stopped as it was on a hill and suddenly the gas engine turned on so the accelerator started to work again. I felt very unsafe and thought I was going to get hit by any on coming cars due to the loss of acceleration. 2nd incident(about a month after the 1st)-Just going straight down a road, pressed on the accelerator and again nothing happened, no acceleration, car sounded like it was turning off, then switched over to the gas engine and the accelerator started to work again. Also, not very safe with cars coming up behind me quickly and loss of acceleration. Had GM look at car, could not reproduce problem, BCEM module already replaced-they could not replace due to GM not approving a second replacement, they would not say car is safe, but go ahead and drive it anyway until the problem occurs again. How many times should this happen before I am actually in an accident because of this problem? I have been the sole owner of this care since 2017 and I have done all the maintenance required for it, I do believe this is a safety issue that should be addressed. I have just been told to drive it until it catastrophically doesn't work, how reassuring of GM!

While driving, a warning message came on: "Engine unavailable." I was able to drive a few more blocks but then the car stopped on its own. This happened despite the fact that the car had almost a full tank of gas. If this had happened on the highway, it would have been very dangerous. Luckily, I was on a fairly empty city street and I simply pulled to the curb. This is a known problem with the Chevy Volt (2017). An independent service center confirmed that the original problem is that the EGR valve needs replacing. When this is an issue, a fuse often blows and this fuse stops the car from moving. The vehicle has not been inspected by the manufacturer, police, insurance rep or others. There was a message that came on a few days before the incident that said "propulsion power is reduced." An independent service center said the EGR valve needs to be replaced. There are no EGR valves available; they have been on back order for months. I have an appointment with the Chevy dealer for next week, so they can confirm the EGR valve needs replacing and I can get on their waitlist to receive an EGR valve. This is expected to take 6-12 months or possibly longer. In the meantime, I can drive the car on electric charge but am supposed to avoid engaging the ICE engine. If I end up running out of electric charge, I am at risk of once again having the fuse blow and the car failing to move forward. This is ridiculous. Why is GM/Chevy not required to provide parts in a timely manner to existing customers to make sure their cars run safely? I am definitely not the only Volt owner experiencing this issue -- there are many people online complaining about the same issue. All of us risk a situation of the car stopping to run at any time.

Starting June 2024 my car started s displaying the check engine light with the message “Propulsion power is reduced” when driving on electric. When the message is displayed it switches to gas even if it has a full charge. Since June 2024 the check engine light is mostly on but sometimes turns off when electric is depleted and it’s running on gas. The message is randomly displayed when I accelerate

I own a 2017 Chevrolet Volt and at about 90,000 miles on the odometer, my dashboard displayed a "Propulsion Power Reduced" message, and upon diagnostic scanning, error code P0401 was detected. This code indicates an issue with the Exhaust Gas Recirculation (EGR) valve. After further investigation, it has been determined that the EGR valve has failed and requires replacement. However, finding a suitable replacement part has proven to be challenging due to limited availability. I had work done to repair the issue at the dealership, but found it wasn't resolved during a recent attempt to pass emissions. This issue is well-documented with Chevrolet Volt owners and can lead to a dangerous loss of power, particularly when driving uphill or in demanding traffic conditions. The sudden reduction in propulsion power could potentially impede traffic flow and create hazardous situations for both the driver and other road users.

While making a 90 mile drive on 7/20, after having depleted the primary battery charge and switched to hybrid mode, a "propulsion power is reduced" warning appeared on the console, along with the Check Engine Light. Other than somewhat reduced power (max displayed of ~40-50 kW), performance otherwise seemed unimpeded. Contacted local dealership to schedule service for earliest available date of 7/26. Car made return 90 mile trip on 7/21 without issue additional issue ("propulsion power is reduced" message remained.) Service identified "numerous codes", but replaced a fuse known to result in the above issue and observed no other issues. Car was driven purely on battery at that time, and for the intervening time until a 170 mile drive on 8/2, where the message and Check Engine Light reappeared, again after battery charge was consumed and car switched to hybrid power mode. Dealership was again contacted to schedule service, slated for the morning of 8/7 (tomorrow, as of this writing). Car reached its destination without further incident. During return 170 mile trip on 8/5, traveling on the highway, car abruptly alerted that the engine was no longer available and entered a severely reduced-power mode. Car had been operating in "mountain mode" (conserving some extra battery charge) as a precaution, so we were able safely exit the highway and pull into a local parking lot, at which point AAA was contacted to tow the car the remaining 120 miles home. Upon arriving home, the car was able to pull into the garage without the "engine not available" alert, but still displaying Check Engine Light and "propulsion power reduced" messages. We have come to understand this is a fairly common issue with Generation II Volts and have been advised by other owners to file this report.

[XXX], while driving on [XXX], check engine light came on with reduced propulsion warning. Continued driving to destination without incidence. Did not drive again until [XXX]. [XXX] while driving using "hold" method of propulsion using internal combustion engine, check engine light remained on, after the engine warmed up, all of the sudden, there was a noticeable reduction of power, followed shortly by the internal combustion engine shutting off while I was entering onto an interstate highway ramp. Fortunately I was able to pull off to the side of the road and back down the ramp without incidence and return home under grossly reduced battery propulsion. July 8, took vehicle to Chevrolet dealership (Baierl Chevrolet, Wexford PA) under battery power. Was told ECM module was bad. ECM module was replaced, error codes cleared, vehicle ran as expected. after driving approximately 50 miles, check engine light with reduced propulsion warning returned. Turned vehicle around and returned to the same dealership. Was told EGR valve was bad while blowing fuse F03 (Non walk home circuit). The dealership did not have a replacement in stock and it would take 7-10 days to obtain a replacement. I had to rent a vehicle out of my own pocket to return home for employment purposes. July 11th, I emailed dealership's service advisor for status of replacement part. Never heard back from service advisor. July 15, 11:24 am, talked to dealership service advisor, was told part was in transit with no estimated delivery date. July 22 called service adviser and left a voice mail message for a return status call. Never received a return call. July 23, called dealership, talked to parts department for part status, was told part had not shipped from warehouse yet and there was no estimate on shipment. After having to return the rental vehicle, I am without a vehicle for my daily required activities. Not an acceptable situations.

I was driving down the highway at normal speeds when I noticed the engine temperature began climbing out of the blue, and eventually the CEL light came on before the dashboard read "Propulsion Power Reduced" and eventually the engine stopped entirely and I had to coast to an area on the side of the highway where I could pull over. The battery-only part of the car was drained but there was plenty of gas in the tank, so my only way out was via the ICE. I turned the car off, waited for it to cool down, then turned it back on, only for the same issue to occur within another couple of miles of highway driving. I had to repeat this process until I was able to get to an exit and coast to a business that would let me recharge the battery enough to drive on battery-only where I could park it overnight, as I was not near my home. Eventually I had to get the car towed to a dealership, where I was told it was either an EGR valve or EGR cooler that needed replacing. After the dealership refused to provide any specifics regarding the diagnostics in writing, Chevrolet corporate informed me that it was an EGR valve that was requested and is on global backorder. This issue has not been resolved for a year now, and put me in the extremely dangerous position of losing power entirely on the highway with almost no warning, and no statements to date that would have prepared me to deal with this issue.

EGR Valve short circuit caused F3fuse to blow causing engine light to go on and Propulsion reduced power warning. The F3 fuse affects 4-5 other systems.

I had the BECM fail as part of many 2017 volts with this issue at around 40K miles. This failure has caused multiple near accidents with immediately losing power at highway speeds. The last time this happened (after the BECM was replaced) was a couple of weeks ago. They said the reason for the failure was a programming issue, and they have updated it. It is flabbergasting to me that a programming issue can result in such a dangerous result. The car reduced propulsion on the highway and got stuck on the offramp while trying to pull over on the busy highway. Not only were we left stranded on the highway with me being 8 and a half months pregnant, but my husband almost got into an accident twice while trying to make it over safely. Chevy needs to be accountable for these significant failures that seem to continuously happen to Chevy Volts. It's not just the BECM - they have multiple things that are causing extremely dangerous results. When they replaced the BECM they also replaced the 12V (with significant out of pocket cost to us) and leaving us with no vehicle for a long time. We bought a new car right after this incredibly scary incident.

check engine light has been on since Oct of 2023 due to needing EGR valve. Dealership placed order for part number 12691147 in Oct and says it has been on backorder from GM with no estimated delivery date. I just placed an order for the same part via GM parts center. Again, says on backorder. Is there anyway to get a hold of GM parts to escalate getting this? We cannot get the car inspected with this issue and are worried about the safety of the car.

The propulsion system stopped working altogether while the car was in motion. The battery charge gauge went from 1/2 to full. The charging information screen displayed a message reading "unable to charge." The air conditioning only blew out hot air, but the coolant temperature gauge read 194-degrees F (within "normal"). The "check engine" light also came on. Diagnostics found the F3UA fuse blown and a faulty EGR valve. A service bulletin for this exact issue was published by GM in February 2023. The company is aware of the issue but is leaving it for customers to discover while operating the vehicle. Safety inspections and oil change centers do not catch this issue. This is a safety concern and should be recalled immediately.

I have needed a new EGR valve for my 2017 Volt for 11 months now. GM told me this in August of last year. I was able to continue to drive the car (without a passing inspection) since then, until recently I was on the highway and my car simply stopped responding to the throttle. I slowly coasted to a stop on the shoulder and was eventually able to get started and off the road, into a parking lot. This is a serious safety issue as I ended up going 20 mph on the highway for a while, which easily could have caused an accident. GM needs to be held responsible for not supporting this part in a timely manner. This is a known issue amongst Volt owners and GM does not seem the least bit interested in making things right.

On a recent trip on a highway on our 2017 Chevy Volt, the Exhaust Gas Recirculation [EGR] failed and caused "low propulsion" errors. We ended up with a surprise bill of more than a thousand dollars to replace the EGR cooler assembly, but the problem was not resolved. The dealership then said we need to replace the EGR Valve which is estimated above $2700 plus labor. Upon checking the GM-Volt users community this is a reoccurring issue on several thousands of vehicles and the inflated price is due to the fact that GM redesigned the EGR valve to fix their original faulty design. We as consumers shouldn't be responsible for such an outrageous cost and mainly safety due to a design flow by GM. This issue should warrant a recall by GM to fix the issue once and for all.

The EGR valve had an electrical short, causing the 15A F03 fuse to blow. This causes a "reduced propulsion" message to appear and also causes the vehicle to start overheating. The faulty EGR valve is available for inspection. This failure occurred while we were on the interstate driving 70mph. We were also at least an hour from home/family. The EGR valve short is a known problem with Gen 2 Chevy Volts. Online message boards are filled with posts about this issue. The vehicle was inspected by a Chevy dealership (we had to have it towed). However, the EGR valve is on national backorder with no ETA on when they would be available again. We are currently driving the car with the valve unplugged. However, this causes the engine to run less efficiently and at higher temperatures, so we cannot run it for long periods of time. There were no warnings before the problem occurred, it just suddenly happened while we were driving on the interstate. Luckily we were near an off ramp and a hotel; since the problem occurred on Easter weekend, there weren't any dealerships open.

Three incidents in the last few weeks. My 2017 Chevy Volt today has about 84,000 miles. First incident, While driving on an interstate at about 50 mph I suddenly lose ability to accelerate. There was some beeping, dashboard turns yellow, I get a low fuel warning and I cannot accelerate. I pull over on interstate. Re-start vehicle and car restarts. Second incident, driving about 20 mph leaving a neighborhood. I have 4 passengers, all kids. The same exact error happens. I’m unable to accelerate though I’m pushing down on gas, fuel light turns yellow. Low fuel light. I pull over. I restart vehicle. Car starts normally. Car goes into shop. Chevy dealership says it’s the catalytic converter. About a week later, 3rd incident. Entering highway at about 60 mph, trying to accelerate and merge into traffic doing 70 mph. I cannot accelerate past 60 mph, I hear the beeps, fuel gauge turns yellow, low fuel warning. Check engine light turns on. Several days prior to this, I had a low propulsion error on dashboard momentarily. But it went away when I restarted vehicle. Safety of myself, passengers and other drivers were out at risk as there was no warning that I would lose ability to accelerate. There was a no fuel warning but my gas tank was mostly full.

While driving down the highway a "reduced propulsion" message appeared on the dashboard and the drive became very rough if speed changed, also the engine temperature increased but it did not overheat before we could stop. This was diagnosed as an Exhaust Gas Recirculation (EGR) Valve failure. I spoke to multiple dealers and did research online as well and this is a very common issue on this vehicle. So common that the part is impossible to get and has an eight month wait which means I cannot drive my vehicle. What component or system failed or malfunctioned, and is it available for inspection upon request? EGR Valve How was your safety or the safety of others put at risk? My car had reduced propulsion, engine temperature increased and it suddenly lost speed quickly on highway when my foot was removed from gas pedal. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, Chevrolet is aware of this issue and say we just have to wait 8 months for the part. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No pre-warning a "reduced propulsion" message and a check engine light turned on at the time of the EGR valve failure.

Driving at freeway speeds when suddenly the cars propulsion power failed and I went from 75mph to 45mph with no warning and no way to accelerate. Happened multiple times even after pulling over and turning the car on and off. I was told by the dealership that was a gas engine part and that I could drive it on the electrical engine only. When attempting to drive on the electrical engine, I received a notice of engine failure and had to coast into the driveway of a dealership. I was told the engine “could explode” if I continue to drive it

The car stalled at a high rate of speed on a freeway because of EGR failure. Engine check light is on, along with a warning about a critical problem with emissions system that requires immediate attention. The part is out of stock in all dealership within a reasonable reach. The problem is under warranty, but I have made multiple attempts to fix this issue with no success.

Check Engine light came on codes indicate the EGR and EGR cooling components have failed and a Propulsion Power Is Reduced message is displayed. Max speed at this point in 10 mph. This would be my second time replacing the EGR valve if the parts were available but they are not and there is no anticipated delivery date. The parts are covered in CARB states (those that have adopted California's emission rules) but not my state of NC.

Driving at highway speed car would slow down on its own and go into "Reduced Propulsion Mode"

While driving on the interstate car suddenly flashed a "reduced propulsion power " warning indicator. At this time the car was speed limited and made us a liability on the interstate. We were about 80 miles from our home so ended up driving the car back home being speed limited. Took car into the shop and was told the EGR valve was bad which kept causing the "no walk fuse" to blow. Ended up having the EGR valve, gasket and cap replaced. All together with labor total for repair was $1,738 on a car that we had only been driving for a year. Bad EGR valves seem to be very commonplace for 2nd generation Chevy Volts but it seems GM refuses to do anything about this issue. I have no plans to every purchase another GM vehicle. Very frustrated!

Had to replace EGR valve after losing power on the highway back in 2022. Lost power steering and reduced engine power while driving at highway speeds, luckily was able to get off the highway and limp the car back to my house. I almost crashed due to loosing engine power and power steering. It's appears to be a BECM issue.

On [XXX] my 2017 Chevrolet Volt with just 24,000 miles on it suddenly jerked/lost power/revved up while on the highway while using the gas engine--frightening/dangerous -- and continued to do that until I got to my destination. The error read "reduced propulsion". I was afraid of pulling off the highway for fear the car wouldn't restart and I had my 91 yr old mother in the car so we bucked along in the slow lane, the car revving fast, then losing power. It was very frightening and i proceeded with the flashers on. Took car to dealership balise in warwick ri. Tech said it was a bad EGR valve. They told me that GM would cover the repair under warranty but the part was on backorder. I opted to leave the car at the dealership hoping for the best but they said another customer had been waiting since September. They told me to take the car home, but i didnt feel the car was safe to drive. Web search reveals this is a common problem and people are waiting all over the U.S. for this part for over a year. Subsequent phone calls revealed that the part may or may not be manufactured ever again, and the dealership suggested I buy a refurbished part on ebay and have it installed at a local repair shop at my cost --- but that would null the warranty, and seemed risky to me. I asked the dealership to buy my car and they offered me $5k less than fair market value-so I declined. Opened a case at GM and they also had no answer, and offered to give me "points" to buy another GM car. Havent had use of the car since because I'm afraid to drive it with the car revving forward and at the next moment losing power. My car has been sitting in the dealer's lot for over 3 months, while I continue to pay registration, insurance and watch the value of the vehicle decline. Dangerous and GM will not buyback or rectify!!! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

50 miles into a 500 mile trip, my Volt displayed a warning message, "propulsion power reduced." It operated almost normally for the first 250 miles and we were able to reach our destination, but the propulsion battery was not able to recharge from the engine power as efficiently as usual. An auto shop at the destination who does not specialize in EVs examined the car and found a fault in the engine control module, but the car was otherwise in drivable condition. On returning home, the car was required to climb a long steep hill. It gave the message "engine unavailable" on the freeway and began running on its battery reserves, which were barely enough to reach the nearest exit. If the car had run out of battery reserves where pulling over to stop would be unsafe, a dangerous situation would have resulted. The car had to be towed home. An EV specialist mechanic inspected the car and diagnosed a faulty EGR valve resulting in a short in the power to the engine control module. The car has been waiting at the mechanic for a new EGR valve for 5 months due to a nationwide parts shortage. Two months ago the request for the new EGR valve was escalated to a "STACK order" but I still have no updates on when the new part will actually be available. Online forums dedicated to the Volt have many posts about cars waiting for months for a new EGR valve. Two weeks ago, I contacted the Chevrolet parts concierge about the issue. They took down all my contact information and stated they would be in touch. Today after not hearing back from Chevrolet, I called the parts concierge again. The staff found no record of my previous call.

WE WERE DRIVING IN TRAFFIC. THE BATTERY HAD PLENTY OF CHARGE. SUDDENLY, THERE WAS A WARNING NOTICE ABOUT PROPULSION POWER PROBLEM AND THE CAR CONVERTED TO GASOLINE MODE. WE CONTINUED TO DESTINATION AND PARKED. WHEN WE WENT TO START THE CAR, IT WOULD NOT START AT ALL. HAD CAR TOWED TO OUR LOCAL CHEVROLET DEALERSHIP (ALL SERVICE DONE THERE) AND THAT IS WHERE IT IS STILL SITTING. THE PART NEEDED (BATTERY) IS ON BACK ORDER. THIS OCCURRED ON JULY 21, 2023. TODAY IS MARCH 13, 2024! AS OF TODAY....APPROACHING 250 DAYS SITTING IN THE DEALERSHIP OPEN LOT,

Check engine light came on and low propulsion warning came on. Took my vehicle to the Dealership and was told that the EGR valve needs to be replaced. The only update I received a week or so later was that the part had been ordered. Now I am being told that the part is currently not available (out of stock) with no known ETA. In reading Volt threads, it appears that this is a widespread problem. I think it is unacceptable that GM cannot provide the parts that are needed to keep this car in operating order. It only has about 40,000 miles.

Propulsion error, steering wheel locked up today, last week shut off to dead stop while idling, trouble restarting. Speed and sudden battery drop issues. 14 miles without any power steering. Unsafe.

EGR valve failed. This can cause the Volt to stall in traffic. No ETA on replacement. The situation seriously limits driving ability. Reduced propulsion and engine light came up. f3 fuse blew related to failed EGR. This is a known issue with Chevy Volts. It was checked out by dealership in Aug. They replaced fuse and basically said can only drive on electric. If turns over to gas it could cause major problems.

The EGR valve had failed, causing a check engine light, which turned into a blown fuse. The fuse blowing left the vehicle stranded until I unplugged the EGR valve and replaced the fuse. I drove it to a shop, where they replaced the valve and the car has been functional since then.

I am writing to report a series of safety concerns regarding my 2017 Chevy Volt, which have persisted despite multiple attempts to address them with the dealership. These issues pose significant risks to my safety and that of others on the road. On January 18th, 2024, I brought my vehicle to the Provo Utah Chevrolet dealer after experiencing reduced propulsion power while driving on the highway, coupled with the illumination of the check engine light. The mechanic performed a quick inspection and used a GM scan tool to diagnose the issue, revealing the code P1E00 for the Hybrid Powertrain Control Module 2, which was cleared without a thorough investigation. I was advised to return if the issue reoccurred. Despite the reset, the problem persisted, and on February 9th, 2024, I scheduled another appointment due to my Chevy Volt's High Voltage battery charging only to 65% capacity despite indicating a full charge. However, upon arriving for the appointment at 4:00 PM, I was informed that the hybrid mechanic had left for the day, and I was asked to return on another day. Subsequently, on February 11th, 2024, the check engine light illuminated again, and on February 12th, 2024, while driving to work, I experienced a loss of propulsion power on the highway, placing my safety at risk. These ongoing issues with propulsion power and the high-voltage battery charging system are not only inconvenient but also potentially dangerous. Despite multiple visits to the dealership and attempts to diagnose and resolve the problem, it persists, indicating a systemic issue that requires immediate attention. I urge the National Highway Traffic Safety Administration (NHTSA) to investigate this matter thoroughly to ensure the safety of Chevy Volt drivers and passengers. It is imperative that General Motors addresses these issues promptly and implements appropriate measures to prevent further incidents.

The EGR Valve on the vehicle went bad, causing the vehicle to display 'propulsion reduce' and 'engine not available' errors on the dashboard before the vehicle came to a stop while driving on an interstate. Searching this issue for the Chevrolet Volt online yields a significant amount of similar issues experienced by other Volt owners. Vehicle was inspected and repaired by a Chevrolet dealership, but seems to be a recurring issue with very limited parts supplied by GM, leading to potential of very long delays in repair time.

Was driving home from work and my car just stopped check engine light came one the engine came on but then went off and i was stranded my issurance came threw with a tow but from all good to a complete stop sucks

My BECM failed on my 2017 Volt. The vehicle set a check engine light and went into reduced engine power 3 times when I was driving it. I took it to a dealer in Metaire, Louisiana. That was 4 weeks ago. I have no confirmation of when the vehicle will be repaired. I have been communicating with both GM Customer Assistance and the dealership, Best Chevrolet in Metaire, Louisiana.

I was traveling at 75 mph with the cruise control on when a message came on about reduced purpulsion. My vehicle lost all power and rapidly decreased speed, the gas pedal did nothing until my speed had dropped under 60 mph. I was on the freeway and could have caused an accident. Chevrolet says a programming update was needed to fix the problem but my BECM is now also out.

Car would not start, lose power, or show propulsion reduced message. This seemed to have been an ongoing issue related to cold weather (bought in July 2019) and would occasionally get temporary check engine lights. Dec 2022 and Jan 2023 cold weather seemed to aggravate w car no starting on occasion. Eventually by January car started propulsion reduced error. Turned out to be BECM (which had been under service bulletin in 2019). Other related repairs like shift to park issue and drained 12 volt battery also repaired at MY personal cost of nearly $4,000. The propulsion issue almost led to some accidents when it would happen pulling into road or on highway driving.

BECM failure on car confirmed at 128,000 miles. While driving the car's check engine light came on; immediately followed by a message of reduced propulsion and the EV range dropping to 0. Vehicle switched to gas and ran very rough for a short distance to an available stop. Have been informed by dealership that the vehicle is now unsafe for driving due to a potential stall.

Driving on the road with a near full electric battery and then lost most of my power and got this message on the dash along with a check engine light. "Propulsion Power is Reduced" - I was in freeway traffic on a hill and had to put hazards on to move to the slow lane. Engine came on and seemed to be revving to full power to maintain speed.

I was in a neighborhood driving ~30 mph and slowed down to take a right turn. Once I completed the turn my car stalled out completely and would no longer accelerate. I tried putting the car in park and back into drive with no luck. I quickly turned the car off and back on and was able to resume driving. As I was just through the intersection I could have easily been hit while motionless and had my newborn baby and wife with me in the car at the time. The issue has no happened again, but I am terrified it might. As there were no warning signs or any signals of problem in the dashboard I don't have any idea when it might happen again.

Vehicle lost power on highway and on local streets. “Propulsion power reduced” warning. Car brought to dealer 7/2023. EGR valve ordered at that time. The EGR valve has not been available since that time. No time frame for availability has been given.

While we were driving on the freeway, we saw a check engine light and “propulsion power is reduced” message. The car began driving very roughly and we had to slow down. We had this happen once before where the car engine stopped working entirely while driving at city speeds after seeing this error earlier in the summer, so we pulled over as soon as we could. We were traveling in a remote area at the time, just before the holidays, and it was fairly cold out. The car dealer inspected the car and told us it was unsafe to drive, that we could not take it back until it was fixed, and that it was an EGR valve problem. We previously had this fixed under warranty as well for similar behavior, and the car is barely five years old with very few miles on it. It’s our only car and we have been waiting on the part for weeks now, with no response on when we’ll be able to have our car back, and no rental car that we can drive in the meantime to get to our jobs and get groceries. The part is covered under our warranty. Both times this has happened to us, we were actively driving. In the city, it was very unsafe for the engine to unexpectedly stop as we were driving because of the amount of traffic and pedestrians, and because it meant we didn’t have full control of the vehicle. On the freeway, it was very unsafe because of the speed we were going on the freeway. Knowing that our engine was at high risk of unexpectedly stopping working while driving on the freeway from the past experience in the city made it difficult to safely concentrate on pulling over and also maneuver in traffic.

1 month ago was driving on toll and Population power is reduced came on, vehicle was reaving high and felt like power was being reduced/speed, was going 70 and had to immediately decrease speed and get off toll and found closest Chevy shop. Looked at dash and vehicle should have had at least 10 energy miles but it had immediately dropped down to 0. Before taking to Chevy, I had a quick inspection done by a Valvoline shop and they told me the battery had to be replaced. Carvana (Silverrock) warranty refused to do the repair under their coverages as “batteries were not covered under warranty” Had it towed from Valvoline to Chevy. Found out Chevy battery was under warranty so it was taken there. Vehicle was checked in and didn’t have an eta as hybrid battery was on back order with no ETA. 3 weeks later the part was received and it was a control module not a battery as the “battery was not failing at the time”. Service called and said vehicle was ready for pick up. Had vehicle for 1 week and was at work starting it up and after 9 hours sitting started it up and low population came back on and vehicle started idling higher than before then after a minute looked at back of car and a large cloud of while smoke started forming from back of vehicle. Immediately turned off car and called gmc roadside assistance to have vehicle towed to another dealership where is it sitting again for diagnosis with no eta.

Propulsion power reduced message appears on dash board. Yes available for inspection. Unsafe to drive losing power on highway. Yes there are warning error messages appearing on dashboard.

Car won't start show codes U2622, U2621, U2620, U2619, P0AFA.

While driving in 60 degree weather, the vehicle’s check engine light lit on the dash and the vehicle abruptly stopped. I was able to push the vehicle safely in heavy traffic. I contacted Onstar who gave me the vehicle diagnosis. Onstar advised the following codes appeared POACA (Hybrid/ electric vehicle powertrain control module requested malfunction indicator lamp illumination), P1AEE ( the electric propulsion system is not performing as expected. Please service immediately), and P1AEF (the electric propulsion system is not performing as expected).

Car stopped operation while out doing errands. Car had to be parked and restarted and made it back home. Car would not start again. Had to have it towed to dealership, BECM needs replaced for $2000. Warranty should cover, but part is backordered. Not sure when it will be fixed and with the recent freezing temperatures could have been dangerous.

Vehicle stopped running, will not restart. ODB codes show failure of the BECM. Check engine light illuminated, READY indication turned off. Vehicle does not display battery or fuel status. We were left stranded by this failure.

While driving the car in electric mode, a chime came on and flashed 'propulsion power is reduced', then it went into engine mode and the car decelerated quickly from posted 70mph speed to less than 40mph even though I pushed the accelerator pedal and reved the engine high. While in this low power driving mode, a warning came on saying the collision detection system was disabled. The concern is the person behind me had no warning since my brake lights did not come on. He sped around me with a bit of road rage. The problem temporarily goes away when you turn the ignition off and back on. I took it to the dealer and the said it needed a new EGR Cooler 4 hours labor $1500. Chevy Dealer pulled two codes P0401 Exhaust Gas Recirculation "A" Flow Insufficient Detected P1E00 Hybrid/EV Powertrain Control Module 2 I paid them the $165 diagnosis fee and got my car back and just plan to restart when it occurs. In another instance, I was pulling out from a parking lot into a busy road in electric mode and the car lost ALL power leaving me exposed in the line of traffic. Error messages on the dash said to 'service BECM' and 'shift to park'. The car was not drivable and had to be towed. Call me if you need any more information.

First, the electrical system did fail suddenly in August 2023. Luckily, I was parked and so was not injured. I did report the electrical failure to the Hendrick Chevrolet dealership in Durham. But this Chevrolet Volt also does not fill up with gas. At the pump, gas just spills out of the tank. I've seen online that many people have this same problem. At the suggestion of Hendrick Chevrolet dealership in Durham (and after paying $210 for a diagnostic), I replaced the vent valve solenoid. The car filled up with gas twice. But once again, gas starts spilling out of the tank if you try and fill it up. The car only has about 25,000 miles on it and hasn't been driven extensively so it doesn't make sense that it is malfunctioning.

We were driving on the highway (my wife and younger son were passengers, and my 17 year old son was driver). He was in electric mode and then the engine propulsion reduced message came on and the check engine light came on. Car was still running, albeit slower. We stopped and filled up the gas, and got an engine unavailable message. Vehicle switched back to battery mode on its own and because there was no charge, the vehicle stopped ON THE HIGHWAY. The car lost all control and power abilities and it was very dangerous. They were able to pull over into the break down lane and they called a tow. Took the car to Mike Reichenbach Chevrolet in SC and they removed and replaced the EGR valve. However, within the last couple of weeks, my son has received the loss of propulsion message again and the car is violently shaking. This is a safety issue!

The Volts BECM has failed. There are warning lights constantly warning about Engine and low Propulsion. There are multiple symptoms. Most serious is that car has stalled while driving 3 times. If I pull over, put in park, then turn off; I can restart the engine using battery mode. It does not drive well in gas mode where gas fuels generator to charge battery for propulsion. It is now very loud and often won't allow you to drive faster than 30 MPH. The mileage diagnostics (MPG) are just over 50% of what they were before problem started. It often randomly switches from battery mode to gas. This is undesired. My problem is that the only certified tech is on other side of Island Volcano. I have no confidence that I can drive it to dealer, given the distance and power required to climb mountain. So, I am stuck with no way to fix. There are widespread reported issues, similar to mine, caused by defective BECM (Battery Energy Control Module). Problem started September 2023 and have issues every day I dare drive it.

Battery Energy Control Module (BECM) on 2017 Chevrolet Volt failed. Resulting in reduced propulsion power, no charging. Check engine light comes on. Dealer has confirmed this is a BECM issue.

EGR valve failed on [XXX] southbound near Cartersville, GA. Initially, the engine showed a Check Engine light, and showed a message that "Propulsion power had been reduced". Approxmately 60 seconds later before we could reach an exit, the engine shut off while driving at 60 MPH. Had to coast/navigate over two lanes while the car was slowing to make it to the shoulder, and was stuck on the shoulder while the engine cooled down enough to leave the shoulder. Jim Ellis Chevrolet confirmed the failed EGR valve, but have so far been able to reproduce the overheating in the shop. Replacing the EGR valve is estimated at $1100, with GM providing a $250 warranty assistance. I have confirmed with other Volt owners that this is a very common issue which affects all GM Volt 2 cars manufactured between 2016 and 2019. Enough of the EGR valves have failed that the part is in short supply with possible wait times of over 6 months. The EGR Valve is part of the emissions system. However, the problem appears to be (unconfirmed) a manufacturing defect in the control board for the valve. This fails, causing the engine block F3 fuse to blow. This fuse also powers the engine coolant pump, which is what takes this from an emissions problem to a safety problem--which can cause the car to shut down suddenly.

My 2017 Chevrolet Volt has had issues with failing to start for years. Many times when the car did start I would receive an error message saying “propulsion power reduced,” resulting in the vehicle being less responsive to the accelerator. I have taken it to get serviced many times only for the issue to persist. Now the car has completely broken down and will no longer turn on at all. The car is currently at a Chevrolet Dealership where a service technician has diagnosed the problem as being related to a faulty BECM (battery energy control module) and that I need to spend thousands of dollars to replace this part. A simple google search showed me that this problem is incredibly common with other Volt drivers, so much so that there is even a class action lawsuit against GM now for this issue (which I received no notice of). I feel like I was sold a faulty car and I now have to pay a price for GM’s negligence.

Loss of Motive Power due to EGR Valve. I was driving down the highway when I experienced a loss of motive power and the Volt entered a reduced power state while in moving traffic. After the EV battery ran out and the ICE turned on, the following message showed up on the instrument panel "Propulsion Power Is Reduced" and the check engine light turned on. The Volt slowed down and would not accelerate to the speed of the moving traffic. I was able to get off the highway and drive home under reduced power which was still not safe. The engine ran very rough on the way home and was not able to maintain speed high enough for the flow of traffic on the roads. The dealer diagnosed the issues as a failed EGR Valve. The part was on backorder for about a month. In that time, a GM trained technician deemed the car operable (according to GM standards) and said that I could take it back and drive it on electricity only. Unfortunately, that meant that the EV range is about 40 miles in winter after a full charge and running out of electricity would again result in a hazardous loss of power. The behavior of the car under this reduced propulsion is Identical to the one in investigation PE23022 - Loss of Motive Power due to the Battery Energy Control Module. The Chevy Volt EGR Valve issue is a common problem reported in other NHTSA complaints and Volt forum posts and I am surprised that there has not been a recall. I hope that this issue is investigated same as the BECM issue. Some examples: NHTSA ID Number: 11558668 NHTSA ID Number: 11557845 NHTSA ID Number: 11557876 NHTSA ID Number: 11557995 NHTSA ID Number: 11483673 [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The latest episode with my 2017 Chevy Volt is a culmination of years of issues with the low clearance on the vehicle causing continual damage and unsafe driving conditions that require expensive repairs due to the design flaw (note - I had a 2014 Chevy Volt that had NONE of these problems). My son was driving the car a week ago and the Engine Control Module (GM part # 12700116) fell OUT of the car. This led to the car to stop driving instantly - if he had been anywhere other than a quiet residential street it could have been catastrophic. Upon having towed the vehicle to the dealership, I was informed that the wiring harness failed which led to the ECM falling onto the street. I drive this car strictly in city limits and on major highways, and despite this the bottom undercarriage is constantly damaged because it is simply to low to the ground. In addition to the repair bill of $3K+ (my 4th repair required due to this defect), the harness isn't even available and GM cannot provide an ETA for when it will be. I experienced a similar issue 6 months ago when a part was backordered for 3+ months and this is compounded by the fact that their dealerships no longer have loan car inventory. Note that there was no warning before this happened. I have tried escalating to GM but their response is essentially that I am SOL. Again - this is a design flaw of the vehicle that should have been addressed but never was. Note that this doesn't include the other continual issues (well documented) that continue to plague the car after other recall service (loss of propulsion, shifter issues that frequently make it impossible to actually turn the car off, etc.)

so we inspected your vehicle and it needs a battery module, that part is on back order and we have no ETA when it will come in. That is what the dealership sent me. There are people on Chevy Volt forums saying it's the EGR valve and they've been waiting months with non-working cars. Is anyone doing their job around here?

EGR valve failed. Dealer supplied part has been on back order for more than five months.

I was driving and then the car turned off and was unable to restart. There was no warning. The car was fine and then it wasn't. The power steering also stops working. Fortunately I was at a red light and not in the intersection yet. The check engine light wasn't on. The BECM (battery control module) failed. I had to get the car towed to the dealership for the repair. The dealership repaired the issue for free since I was still under warranty.

All of a sudden while braking on a freeway offramp, the check engine light came on and a reduced propulsion warning came on my screen. The car ran weird for about a day, then it wouldn't start. I had it towed to a dealer, they diagnosed the BECM went bad, now my car has been there 2.5 weeks and there's no estimated ship date for the part, much less repair date. If they said they had enough parts for BECM failures, they're either lying to you or they're lying to me.

The BECM located in the battery compartment failed The vehicle was completely immobilized and would turn on but would not "start" leaving me stranded. Away from home. The local Chevrolet dealership confirmed the BECM was at fault The vehicle gave no clear indication of a pending BECM failure before the failure

Consistent BCEM failure with volt. Power Reduced even if battery has full charge and gas is in tank. Forward Collision made unavailable without reason whilst driving. I rely on the forward collision system while driving at night in my area because of drivers cutting each other off constantly, so losing this feature without knowing why it failed feels unsafe to me. Forward collision would also activate when no vehicle is infront of me causing the car to suddenly stop and jerk on the road. Propulsion power is reduced is an extremely common occurrence in my volt. It happens randomly while driving and even while charging. When I'm on the highway the car would slow down when the warning came on; even with cars right behind me. I'm scared one day the car's system will cause an accident because of it's unpredictability. Regular maintenance has been performed and no issues have been found. The problem continues to persist.

On 3/11/2023, I was heading home when my vehicle lost power in the middle of the freeway. Luckily, I was able to safely pull over to the side of the freeway. Since this is a plug-in hybrid, there are two gauges showing how much electric and gas is in the car. When I checked, both showed were empty; however, although I knew that I did not have much electricity in the battery, I had nearly a full tank of gas. The vehicle should have had automatically switched over to the gas but did not. After a few minutes of leaving the car off, I was able to restart the vehicle in gas mode and drive home safely. I brought in the vehicle to my local Chevy dealership to have it diagnosed. It was determine that the computer had registerd multiple faults p0030, 31, 54, 135, 403, 405, 443, 458 and 537. They also found TSB 21-NA-116. They had found that the 15 AMP fuse was blown. They had to replace the EGR valve assembly. Total time was 2 weeks to repair as they had to wait for the parts from Chevy. Per WO, parts 12346290 (Coolant) and 12691147 (Valve) were replaced. After replacement, vehicle have been running fine for the past 9 months. Prior to the engine shutting off, there was a message on the screen while driving which says "Propulsion Power is Reduced". The electric gauge was empty but the gas tank show nearly a full tank.

Vehicle malfunctioned and was unable to be driven. Had to tow to dealership where they diagnosed the problem to be a BECM board, and new HV battery. It has been at dealership for 6 weeks at this point, with no ETA on new battery to arrive.

BECM starting to fail. Will work and then won’t work. Having issues intermittently.

The car regularly reports it is healthy and functioning correctly. It is regularly serviced and there was no advance warning of this problem. While driving the car displayed a message to the driver, something such as "reduced propulsion" and the speed of the car was reduced while the internal combustion engine intermittently raced in an uncharacteristic manner. The amber Check Engine light was displayed. A review of error codes later found a communication fault developed with the Battery Energy Control Module (BECM). As soon as it was possible, we got the car to the side of the road and shut it off. We then attempted to start the car and it displayed a warning that no key fob was present (but there was a key fob in the car). A few minutes later the car started and we were able to drive it to a service center where error codes were captured. Afterwards, the car drove as normal, and later even the amber Check Engine light was extinguished. The service center explained this could be an intermittent problem where the car will suddenly throw the error message ("low propulsion") and the car will have to be pulled to the side of the road. It will be a few weeks before the service center can do any work on the car. Since the car may start and drive, but suddenly find its speed reduced to far below the speed limit, the car can no longer be safely operated.

While driving to work, the vehicle shook a bit and entered into "reduced propulsion mode". The vehicle had a significant reduction in engine power on the road (the propulsion became very jerky), which became dangerous on the highway. There were no previous indicators of any type of issue. After brining the vehicle to the dealership, I was told it would be okay to drive until my appointment (which was scheduled for the subsequent week). Two days later, the vehicle would not start. When attempting to start the car, the "Shift to Park" message displayed. I had to get the vehicle towed to the dealership at that point. The dealership mentioned it is likely an issue with the Battery Energy Control Module (BECM). However, I'm still waiting for a resolution.

The battery energy control module failed mid drive causing my car to come to a stop in the middle of traffic. The car was towed to a dealership mechanic shop where the BECM had indeed failed. There was no signal that is was going to fail it just simply stopped and as it stopped the check engine light came on

Battery Energy Control Module failed resulting in significantly reduced and unreliable propulsion power available reducing maneuverability and increasing risk of collision at speeds over 45 mph. Check Engine Light illuminated as well as a “propulsion power reduced” message on the dashboard. The problem was confirmed by a dealer and repaired under 8 year / 100000 mile voltec warranty.

On 2 separate time periods, "propulsion power reduced" message appears on dash: - 1st incident in November 2022, car would not move after powering off the vehicle. After sitting idle for a week, decided to retry, and car seemed to work normally. Took it in to Chevy service, they replaced the BECM. Car worked fine after this - 2nd incident in November 2023, again 'propulsion power reduced' message appeared. This time, however, car would suddenly cut off gas engine (even at highway speed), switching to 100% battery mode, and displaying 'Engine not available' on dashboard. Fuel level indicator would immediately display 'LOW' (even though gas tank was full). Reduced acceleration on battery mode. Car is now in same service center awaiting fix for the past month. Was quite an unsafe situation, especially at highway speeds, and especially given the fact that the battery also may have been at a low state of charge, risking complete vehicle breakdown. Coupled with both of these incidents, the cruise control intermittently shuts off, displaying 'Cruise control unavailable'. Car is lightly utilized, with just over 30k miles on the odometer to date. Additionally, the car is kept in a mild climate (coastal southern california) and parked in a covered spot shielded from sun and temperature extremes.

The gm repair started the "vehicle power control module" - gm (24296765) is bad. Cause the car to stop, and not restart, 12v won't charge. dealership states the part on back order over 60 days, not expecting it any time soon.

The car started stating "put in park" every time I would try to put the car in drive. I would shift back and forth from park to drive over and over and I could get it to clear. One time it lost all power and had zero control. Sat on the side of the road for an hour. Shifting back and forth until it stopped and let me engage the drive. The last time it happened in a parking lot and it would just say"shift to park" I couldn't get it out of park. Had to have the car towed. Tow driver had to drag the car on the flat bed with a wench because it was stuck in park. Had the vehicle repaired. Replaced an electronic control module that had previous service bulletins on but GM would not cover the repairs. I was lucky I was not injured our involved in a wreck when I experienced these issues. I was not aware I could file a report about this until I read there was an open investigation on the same issue I had.

I was driving on the freeway and the engine turned off. I was able to continue driving as the hybrid system still had some charge to continue powering the car. I had to get the EGR valve replaced. No warning lights prior to this occuring but had check engine light after. Car would not shift into drive nor would it accept a charge for the main drive battery. Had to be towed to a shop and resulted in getting the Battery Energy Control Module (BECM) replaced.

The EGR valve failed, causing the loss of propulsion message on July 11 2022. This was fixed, however the message was received again in December 2022.

1. 2 BECM failures: The original BECM failed and the replacement BECM failed as well. 2. Sudden loss of electric propulsion on the freeway while my wife (pregnant at the time), my son (1 year and a half) and I were driving. The car was still driving but was unstable when steering and with weak braking. The dealership identified the issue as BECM failure and the part was changed. 3. A couple of months later the car would not start at all leaving me stranded at work. The car was towed to the repair shop. The dealership diagnosed BECM failure again. 4. There was no warning indication or message prior to these issues. 5. The vehicle was only inspected by the dealership to the best of my knowledge.

Sometimes when the vehicle powers on, it will not engage to drive in gas or electric mode when fully charged or with a full gas tank. Also sometimes while driving, it will say "gas mode not available propulsion limited". It frequently says "charging not available" as well. This is an on going, intermittent, problem.

My Volt will suddenly lose propulsion. The air conditioner will stop working and the car will not properly accelerate. There has also been multiple occasion where the car will not power on. Additionally, there has been multiple occasions where the car won’t charge. The failed component is most likely the battery engine control module. My safety and that of others is at risk because of the sudden loss of power and inability to maintain highway speeds. The issue was confirmed at the dealer. The check engine light goes on even after erasing codes, and there are 13 permanent codes related to this issue with no direct resolution. This is a recurring problem.

Started acceleration on the freeway, car couldn't turn on engine, message came on dash "reduced propulsion mode" and check engine light came on, could only drive on battery, car was very sluggish, luckily had battery to exit after a few miles to get off the freeway. Had to restart car. If I had depleted the battery as I usually do that day, I would have had a dead car on the freeway with ton of traffic buzzing me and my family.

On Nov5th 2023 the dash displayed "Shift to Park" and "Unable to Charge" and would not move. New 12v battery installed on the 7th, still had issue. OBD codes pointed to MAF and MAP sensors. Both replaced, but now "Reduced power" displayed on dash and erratic and limited to 30 mph driving function was experienced. PRND shifter replaced and car worked fine for 1 week. Then "shift to park" and difficulty to move car was happening again. Called dealer and under "reduced power" drove car to dealer on Nov 22nd. Car was erratic and I felt like it would stop moving at any time while in traffic.Now dealer has has car and they say they are not sure of solution and parts may take weeks to arrive. Saw article in Reuters about other Volt owners with same problem on Dec 1st, so I'm adding my car to the group. Thanks!

Car intermittantly lost propultion while driving. this started happening more and more frequently. One time driving on the freeway propulsion cut out and I barely made it to the side of the road. Put the car in park and it would start again. Drive for a few hundred feet then it would cut out again. Finally took it into the dealer when I was driving down the highway and propulsion cut out and I was stuck in the middle of traffic. As I was driving the instrument cluster power remained on but the engine just cut out. I was using the electric motor at the time but this is happened on the ice as well. As I rolled to a stop in the middle of traffic I put it in park so that I could restart the car as I had been able to previously but it would not start. It would not let me shift the car out of park into neutral so I could push it to the side of the road. After several attempts of disconnecting the battery and the high voltage battery I was able to get the car out of park into neutral. Even when I shifted the car into drive the propulsion system would not work, a officer stopped traffic to allow me to push the car to the side of the road. After getting to the dealer they were able to determine that a ground strap to the engine chassis was at fault. It interrupted the communication on the can bus which wouldn't allow the ECU to communicate with the drivetrain Which just shut down the propulsion system. This was extremely scary I have attached a snapshot of fault codes and snapshots of a video I took showing that the screen would just show that the car was initializing the entire time

During a drive the car began warning of loss of propulsion. The vehicle is at a dealer waiting for repair since Oct 16, 2023. There is no ETA on back ordered EGR valve that the technician anticipates a fix.

I was driving home from a client meeting on the highway and received a check engline light with the message "Propulsion Power is Reduced." After a trip to the dealership, I learned that the car's Exhaust Gas Recirculation (EGR) valve malfunctioned and needs to be replaced. Some online research shows that this is a very common issue with Chevrolet Volts. What's worse, the part is back ordered indefinitely because they're not manufacturing enough of them. I know NHTSA is looking into the Battery Energy Control Module (BECM) issue as well. I'm very worried about when happens when/if this fails too and if it happens out of warranty. There should be recalls on both of these common failures and GM should make sure there they're a) all replaced and b) people don't have to wait months to get parts needed for their cars.

BECM failure, covered by warranty but required towing that I had to pay out of pocket. Have been waiting a week for the repair to be completed and the dealer is refusing to provide a loaner vehicle.

Any time the car switches from battery to gasoline the 12v battery comes on, I get the message to shift into park, and the car shuts off. This happens multiple times a day, making it difficult to drive long distance. It also makes it difficult to work more than a couple of hours at a time as an Uber driver. It has happened on the highway, very dangerous.

Car is having a few problems in relations to the BECM

-- My 2017 Chevrolet Volt experienced a failure of the Battery Energy Control Module (BECM) in the powertrain system. This failure prevented my vehicle from being driven. The BECM and related battery pack components were replaced under warranty by a Chevrolet dealership. Those parts, to my knowledge, are not available for inspection. -- From a safety perspective, my vehicle was luckily parked when the failure occurred. Many Volt owners have reported -- via online Volt forums and on Reddit at r/volt -- that the failure has occurred while the vehicle is in motion, resulting in a safety issue when the vehicle loses power and stops in the middle of a street or highway. -- A Chevrolet dealership confirmed my vehicle's BECM failure through diagnosis and code reading (see attached documentation). In my case, the BECM initially failed and I lost the ability to drive my vehicle when it was stopped in a parking lot (while I was on vacation, 225 miles from my home). I left the dead vehicle in the parking lot overnight. The next day I was able to start the vehicle and drive it to the nearest EV-certified Chevrolet dealership, where the BECM permanently failed in the dealership's service entrance. I watched the dealership service staff push the dead vehicle into the service bay. It should be noted that I was lucky -- the replacement BECM part was available from GM to the dealership in two days. NHTSA will receive complaints from other Volt owners who waited weeks and MONTHS for a replacement part and repair, all the while their vehicle could not be driven. -- My vehicle's BECM was inspected, the failure diagnosed, and the part replaced by a Chevrolet technician at a Chevrolet dealership (see attached documentation). -- The BECM failure on my vehicle happened immediately with no warning. When I could not drive my vehicle, I saw cryptic "propulsion lost" and "shift transmission to park" error messages on the instrument panel.

Cart fails to start nearly every time I try to start it. BECM failure seems to be the issue. Car instructs to shift to park then fails to start until eventually it clicks over and will start in gas mode. Sometimes will randomly flag into low propulsion mode while driving, which majorly affects acceleration speed. Car will no longer charge and must be used in gas mode due to known electrical defects. Sometimes have to wait 10+ minutes for the car to start.

The EGR Valve has failed and they have not provided a replacement yet. Been 4 months. Decline to give an ETA.

In the last couple months, have received multiple warnings regarding reduced propulsion that, as I understand is a potential failure related to the BECM. Besides the warning, I haven’t noticed any major change in performance, but I am concerned there may be a defect. I haven’t yet contacted dealer about this issue, but I noticed there was a formal report made about this and wanted to be sure my vehicle was included in the count.

The check engine light came on in my car with the message "service charging system." I took the car to the deal and they determined it was the battery control module that was failing. They told me the car would eventually stop turning on and I could either take it and drive it until it wouldn't turn on or I could leave it with them until they got a replacement part that is currently on backorder with no estimated time they can get it. I asked if the car was safe to drive and if it would stop working while I was driving, they assured me it would not stop while I was driving. I opted to take the car home and on my home, while driving, the car died on me. Luckily I was already in a turn lane and was able to get off in a neighborhood. The car gave me a message "propulsion system unavailable" while I was driving and would not power the car forward or backwards. This happened about six weeks ago and I am still waiting for the replacement part.

As reported by the dealer the Battery Energy Control Module (BECM) has failed. Car initially did not start but then did start with a check engine light and a "Propulsion Power is Reduced" warning. Vehicle has approximately 56,500 miles. Car could have abruptly stopped or slowed considerably while driving. Chevrolet dealer is blaming the current UAW strike for complete lack of replacement parts. They also state there is no way to forecast a delivery date of the part. I am out a vehicle for an unknown amount of time with no promise that GM will reimburse me for out of pocket expenses for a rental vehicle.

While driving after the electric battery is used and switches over to gas, I have been getting the check engine, ABS, steering, parking, and brake lights. I have lost power steering, lost the speedometer, lost fuel range, lost stabilitrak, it has randomly turned on the emergency brake while all these other things are happening, It also has said “shift to park”, propulsion power reduced. I have taken it to the dealer and they read some of the codes but say they can’t find anything wrong and they need to be able to reproduce the problem to find it. I lost all propulsion and pulled over and turned it off and it stopped with a “clunk.” Then I turn it back on and just the check engine light is on. I’m very afraid to drive it but with the lack of vehicles available to buy and the dealer not knowing how to fix it I don’t know what to do.

Random no starts, engine turns on at random, won’t charge, car jerks, hesitation while driving, hard to climb mountain roads, Battery Energy Control Module Lost Communication With Hybrid/EV Battery Interface Control Module 1-12

The vehicle suddenly, and unexpectedly lost propulsion while driving. The vehicle is no longer able to turn on or drive. I contacted several Chevy official dealers and took the car in for repair. They said it is a problem with the hybrid battery system. But the car is no longer manufactured and parts are no longer available. So I am now stuck with a car that is non-operational and not repairable.

When I first purchased the car (used around 30,000 miles), I began to have electrical and propulsion issues where the engine would turn off. After Chevy refused to warranty or lemon the car, eventually the electrical/hybrid issue repeated and caused cooling issues with the car and then water pump went bad. while chevy still refused to fix the hybrid and battery issues, that continued issue and then the water pump failing from it then caused overheating that then broke the head gasket

After the battery runs out, the engine loses propulsion and fails to run on gas. The car completely stalls in the middle of traffic. The speed drops from 70+ mph to 0. Extremely dangerous to myself and others. The issue suddenly appeared at the end of December 2022 during a long drive. The engine check light remains on and a warning re: reduced propulsion power is displayed every time the car is turned on. Dealer is unable to fix the issue because they already have multiple cars with the same issue waiting for weeks to be repaired. Recently filed class action law suit suggests that this problem is caused by defective BCEM unit.

The Battery Energy Control Module (BECM) has failed. On two occasions this put me at risk of collision because when the BECM lost communication my car stalled as I was accelerating away from a stop sign. On one occasion, cross traffic had to come to a stop so I could push my car out of the intersection. The car is currently at the dealer for repair. The problem has been confirmed to be the BECM. There was no advance warning when this occurred. A message came up during the incident that said, "Propulsion Power Is Reduced" and following the incident, the check engine light illuminated. The warnings appeared at the time of the incident. There was no advance warning.

BECM failure. Initially, it caused the vehicle to operate in a low propulsion state. However, it now prevents the vehicle from starting. Likewise, I have heard it has stopped the engines from working/shut down the engines while people are driving on the highway.

About 3 minutes after I started driving the 2017 Chevy Volt, an error message showed saying "propulsion power is reduced" and I was unable to drive the vehicle as typical. While driving on base at fairly low speed (~15-20mph) in the battery area of the display, the EV range was reading 12mi, and it started going up. When it read 20mi, the "Propulsion power reduced" showed on the display and the check engine light came on. I pulled over to a different building, went inside for a few minutes, came back out and restarted the car, and I got a message the Volt wouldn't initialize. After multiple on/off button pushes to start the car, the car finally initialized to where I was able to drive home in the "Propulsion Power Reduced mode", and I was not able to accelerate as expected - the vehicle was very sluggish. I drove home at about 45-50mph. My drive home is about 38 mi one way.

On Sunday night, I was driving around 65 mph on the 405 freeway to take my friend to the airport. I noticed that the car started to give a weird feedback sensation on the pedals and had started to jerk us forward. As I merged onto the two-lane on ramp to the 10 freeway, the car started to rapidly lose power and then completely died and went dark. I was unable to use the hazard lights as the car had just gone dark but then it turned back on but would not let me shift it into drive. As I was on a two-lane on-ramp with no shoulder in the dark, we just had to pray that no one would hit us. In doing research, I suspect that this was yet another BECM failure that has been repeatedly happening with this year of Chevrolet Volts. There was most recently a class-action lawsuit filed for this very issue. The car is currently at the dealership awaiting inspection but I am terrified to drive that car again if it even becomes drivable. Especially since there were no warning lights or signs on the vehicle to indicate that this could be an issue and to have it die on the freeway in the way that it did, putting my life and many other lives at risk, I am shocked that there hasn't been a recall for this issue.

Battery Energy Control Module failed. Car stopped unexpectedly while driving which was a huge safety issue. Car has been broken for 3 months waiting for parts which seem to be unavailable.

I have owned my 2017 Volt since November of 2016. I drive about 200 miles a week and currently my mileage is at 109,000 (9,000 miles PAST the warranty period). My car did not start one morning and had to have it towed to my local GM dealership. They diagnosed it with a bad BECM and a repair bill of $1,400. They have no estimated time on when the part will be shipped. It is unacceptable to not have an ETA for a critical part or the vehicle. I have read on many forums that the BECM is a known failure for the 2017 Volt.

Vehicle started to lose power. Showed error messages "reduced power" after a series of "shift to park" messages when first starting. Had no propulsion power until several attempts to start vehicle. Once started engine would run but all electric propulsion was inoperable. Vehicle has become totally unreliable at approx 22,000 miles, sometimes starting and sometimes not. Power loss occurs while driving which is definitely a safety hazard if on the Interstate and minimum speed can't be maintained. Have taken vehicle to dealer where it was diagnosed as a defective "BECM" (I believe a master control module attached to the main propulsion battery). The dealer has ordered a replacement module but it's been four months with no sign of a replacement. Essentially I now have an unreliable and potentially unsafe vehicle with no sign of the manufacturer trying to facilitate repairs.

Emergency warning messages appeared on 24 Aug 2022 and a day later vehicle was taken to Chevrolet dealer who first replaced a "section of the battery" and eventually verified a problem with the BECM (Battery Energy Control Module). Now (end Nov 2022) 3 months later no repair part has become available. Because we immediately took the vehicle to a dealer, we had no safety issues.

Vehicle went to low propulsion mode and would not move at a stop light during rush hour traffic. After many trial and errors restarting the car it finally moved under low propulsion mode. We were almost hit from behind many times because of people at the last minute turning around a stalled car... GM diagnosed the issue as a bad BECM (battery energy control module). Our service rep said it is a very common issue with this car and that they have a few others waiting for a replacement part. I am at month 2 waiting for my vehicle to get fixed.

A problem occurred on approx Sept 25 where the vehicle dash suddenly displays "shift to park" and no longer has any propulsion. This is dangerous, as in this case the car was stuck in the middle of traffic unable to move to the shoulder. Luckily someone helped push my wife out of the road. This is the 2nd time this summer (2022) that this has occurred. It has also occurred in the more distant past. The car goes into a mode where it cannot fully shut down or started. Shifting out of Park simply bring back the message of "Shift to Partk". I have found the only way to get the car moving was to disconnect and reconnect the battery to reset the computer. Vehicle was brought to dealership for service. Tech could find no issue associated with this problem. Shifter was replaced just to rule that out.

Traveling from Mexico ,we just got into yuma Arizona heading towards the 8 freeway when my volt displayed reduced propulsion and the engine light came on and the car lost power while driving on the road we had to let the car drift into a parking lot. We let the cat sit for a several minutes and the engine started up but was running hard. After that it ran a little so we decided to rent a uhaul and car hauler to get the car home. Before this happened We were about to head back to California and we were stranded there until we got an Uber to the uhaul place and rented a truck and car hauler, the car would stay on long enough for us to drive it up on the ramp so we had to push the car to get it up there. We finally did and 24 hours later we made it home hauling the cars a 3 hour ride home was turned into a nightmare. Apparently this is serious problem if the car would have stopped a while we were driving through Joshua Tree we would have been stranded on the side of the narrow road in the dark, Or on a major free way, This problem is a safety hazard to all Volt owners and it has been known and reported to happen countless of times so why is there no recall of these vehicles for this problem, people's lives are in danger, this could have turned out way worst, thank God He saved us from what could have happened. My dealer says that they are not sure what caused it and that we may have to pay for repairs. This is unacceptable because there is an obvious problem with this vehicle

At approximately 61,500 miles my Chevy Volt would not start. I had it towed to a repair facility who determined the problem was a faulty BECM (Battery Energy Control Module), but that it would still be covered by the manufacturer's warranty. So I had the vehicle towed to a dealership. The vehicle has been at the dealership for six weeks as of the time I write this, but report they have yet to diagnose the problem or offer a solution. Doing research online I have found that BECM failure is a common problem among the Chevy Volt, of all model years. And due to "supply chain disruptions" people are having to wait weeks to months for their vehicle to be repaired. Fortunately my vehicle did not fail in a dangerous location, however the BECM failure could happen randomly at any time at any mileage and appears to be a design flaw. Fortunately my vehicle is still covered by the manufacturer's warranty, but in my opinion, repair should be extended to all Chevy Volts.

BECM failure caused vehicle to lose propulsion. Could have stopped working in a dangerous situation such as an intersection, steep hill, or railroad tracks.

This is related to a long-standing issue with the failure of the Battery Energy Control Module (BECM) (part #242969-00) for the 2017 Chevrolet Volt, as well as a lack of availability of the replacement part. This is a documented problem in the NTSA database since 2016. The vehicle error messages on the dashboard include “unable to charge”, “shift to park to start”, “reduced propulsion acceleration may be limited”. The internal combustion engine engages even with a full battery charge on an intermittent basis. Only after turning the car off and on several times or later the next day, would the problems resolve. In several instances, there was a lack of power transfer to the wheels when in drive mode and traveling on roadways, and the car had to be turned off and on to resolve this problem. The car has been inspected by a Chevrolet dealer to confirm the BECM is failing and needs to be replaced. The replacement BECM was ordered by the dealer 7 June, 2022, and neither GM or the dealer will provide a delivery date for the part. A number of postings on www.gm-volt.com reported 2017 Volts would no longer turn on or would lose power when being driven, could not be driven, and had to be towed. The NTSA database indicates approximately 250 complaints have been filed for 2017 Volts that include vehicle error messages on the dashboard for “unable to charge”, “shift to park to start”, “reduced propulsion acceleration may be limited” and loss of power while driving. Although no accidents or deaths were reported, this is clearly a serious safety issue that NTSA should address immediately with a mandatory safety recall.

When attempting to engage the vehicles drive system, it would occasionally fail to recognize the propulsion system battery. This could potentially leave someone stranded in dangerously high or low temperature environments without food or water. Powering off the vehicle and then powering the vehicle back on would sometimes fix the issue. The issue occurred very randomly and was unable to be reproduced once working again. It would continue to happen more frequently and require more tinkering to get it working until almost complete failure. This appears to be a common issue and found to be the result of a failed BECM (battery energy control module). It triggers the check engine light and a series of trouble codes. It is estimated that the replacement of this module takes roughly five hours. Unfortunately, supply chain issues have recently resulted in owners being without their vehicle for multiple months with no loaner vehicles available and no additional compensation. See discussion https://www.gm-volt.com/threads/becm.343297/

from all my reading and my own knowledge and what I have read on forums from others who have had the same issue, this problem is due to the cars BECM (battery energy control module) going bad unexpectedly. apparently this has happened to many other people driving the generation 2 Chevy volt at varying mileages. On the highway on her way home from work, my wife experienced a large loss of power and the car started shuddering and switching between the electric and gas powertrain as well as slowing down quite a bit. the dash showed a notification of "propulsion power reduced". the car also lost power to many of its accessories. she ended up having to pull over on the side of a busy highway and turn the car on and off again till it would finally work and managed to limp it home along back roads. if she had not had a shoulder to pull on to she would have been stuck in the middle of the highway. the car had absolutely zero issues before this, but since the incident has had a check engine light illuminated and is unable to charge unless the codes are reset. it is drivable again after getting some codes cleared but as it poses a serious hazard we are trying to find a temporary car till we can get this fixed. our car has about 100900 miles on it, but these failures happen as soon as 25k-50k on a lot of vehicles. it has not been inspected by anyone yet as it happened yesterday.

2016-2018 Volts are have a hung issues with the Battery Engine Control Module (BECM). When it fails, the car stops driving and will shift itself to park. Mine lucky failed when I was stopped but the car is unable to move when it fails. It will not drive on the motor or the battery.

I was driving and put my car in “hold” mode and received an error message ‘propulsion power reduced, engine not available’. I was preparing for a ~300 mile drive and so I pulled over after a few miles to see if turning it on and off again would do anything. My car kept saying ‘shift to park’ and wouldn’t turn back on. Finally got it to turn in and tried the gas mode again and got the same error. Dealership not open due to holiday and am now missing out in plans because I can’t drive in gas mode

On 2 difference occasions over the past 3 weeks, my car has malfunctioned while I was driving. There were no warning lamps, messages or other symptoms prior to this. All of the lights on the dash came on, the power steering went out, the brakes would not work properly and I could not accelerate. I had my child in the car and we narrowly avoided being hit by other cars both times since I couldn't control the vehicle. I couldn't even power the car down initially but was finally able to turn it off and back on and function resumed after several cycles. I was driving on electric battery that time. The first time, the dealership stated that the following codes were present: P1e00 and P16BA. They replaced the g1 a/c compressor. The incident occurred again a week later when I was driving on gas. At that time, there were history U codes present for every module, per the technician but no current codes to identify the problem. The problem has not been able to be reproduced since. The 2nd incident occurred out of state and my car was towed back to Texas where I live. The dealership there refused to investigate the incidents since they couldn't reproduce them and there were no current codes showing. It has subsequently been towed to a different dealership where they are still trying to identify the issue. I contacted General Motors and was contacted by a rep who escalated the issue. The next rep escalated it again greater than 48 hours ago and I have received no further contact from GM. The 2nd rep informed me that since the dealership that it was originally at says that it's safe to drive that they can't do anything. This car is NOT safe to drive.

While driving in the EV-mode in a traffic the car suddenely lost its ability to accelerate. The ICE started, the CHECK ENGINE icon appeared. I managed to park in the right lane with hazard lights flashing, but my car caused a traffic jam. The battery showed its present capacity, but the drive mile estimation showed only 1 mile. After some shutoffs/starts I managed to get home. This happened one more time after a day or two. It could cause a collision from behind as again the car lost its propulsion ability unexpectedly.

I was driving 65 miles per hour on the freeway and suddenly my car lost propulsion. A light came on that said the car had lost propulsion and I had no power to keep driving on the freeway. Luckily, I was able to get to the side of the road without getting hit by other cars, but it was a close call and very scary. I had it towed to the dealership and they could not find any problem with it after investigating for an entire week. They gave it back without any repairs because it was apparently working fine for the dealership. This same problem happened again about 6 months later as I was driving up a long hill. Again, it was a scary close call to get to the side of the road safely. This time I just turned the car off and let it sit for awhile. Then I turned it back on and everything seemed to be running just fine. This is a major safety problem. I’m now afraid to drive this car and no one seems to know how to fix the problem!

My car, like many other 2nd Gen Volts, experienced a BECM failure that resulted in two events where the car unexpectedly lost all propulsion power and came to an uncontrolled stop. I believe the electric power steering was also disabled in both events. Luckily these events both occurred at low speeds, not on a crowded highway, as I do not believe this failure would allow the driver to get to the shoulder. The car was immobilized after both events and needed to be reset to drive home in a 'reduced propulsion' limp mode. There were not, to my knowledge, any warnings, CELs, etc. before the first event. The car has been with the local Chevy dealership for over two months waiting on part availability, as this is a common failure. It appears from online discussion that this is extremely common on this year and make.

Check engine light came on during highway driving and dash showed "Propulsion Power Is Reduced". Dealer said bad EGR valve and/or EGR cooler caused fuse to blow. Replacing fuse did not resolve the issue as it occurred again. EGR failure is a common issue with this vehicle and there is a GM service bulletin 18-NA-089 issues in March 2018. Driving with this condition can cause the engine to overheat as well as cause increased emissions due to the EGR being non-functional. This condition can be dangerous if the engine overheats and shuts down during highway driving. Emissions control systems such as EGR should be covered by the manufacturer but I had to pay out of pocket for this repair.

EGR Valve in 2017 Volts is faulty/defective 1) Right from the time the car was brand new, smell of exhaust in Cabin when engine warms up 2) When EGR Completely failed a) Loss of Propulsion b) Strong burning smell in cabin - like plastic burning No such problems with new EGR installed Here are lots of other people's similar problems with the EGR Valve https://www.gm-volt.com/threads/2017-interesting-egr-valve-failure.328621/ https://www.gm-volt.com/threads/2017-egr-valve-walk-home-fuse-saga-update.339078/ https://www.gm-volt.com/threads/17-volt-w-68k-miles-p0401.338840/ https://www.gm-volt.com/threads/2017-premier-25k-reduced-propulsion-power-overheated.338864/ https://www.gm-volt.com/threads/2017-fuse-f3-blown-egr-valve-part-12691147-is-out-of-stock.339131/ https://www.gm-volt.com/threads/2017-egr-problem-at-25k-miles.334723/ https://www.gm-volt.com/threads/2017-engine-not-available-yikes.339067/ https://www.gm-volt.com/threads/egr-valve-being-replaced-2017-volt.340639/#post-5063406 https://www.gm-volt.com/threads/replacing-egr-value-yourself.341033/#post-5068080

The car suddenly started starting problem, then the electrical charging component to refuel the power from an electrical charging outlet was unable to charge. Now it does not start at all. I brought the 2017 Chevy Volt to a dealer, it has been more than a week and they said that the part to fix the problem is not available yet and I have to wait. They do not have any idea when they will get the part.

Hello my car says shift to park from time to time an I can't move and whenever I turn with my electric mode sometimes it stutters and switches to gas.

While driving on the interstate at 75 mph I had to accelerate briefly to allow another vehicle to merge safely onto the road. Immediately my dashboard gave me a warning message saying “reduced propulsion acceleration may be limited” and the engine warning light came on. The temperature of my coolant began to rise over 230 F & then 240. Miles from my destination, I reduced speed & took the next exit to stop for fuel and read my owners manual. I discovered that the same message could appear if the car was not put into “mountain mode” thereby failing to reserve a certain amount of energy in the battery. I had hoped we starting the engine & resetting the computer with the car in “Mountain mode” would resolve the matter, but that was not the case. I let the engine cool down for a bit & restarted my trip as I was just 20 miles away from my destination. Later on, I got another message as my engine began frequently skipping and sputtering that told me my “engine as not available” despite having a bear full tank of gas. I pulled over to read the manual & discovered that this message indicated once my car ran out of electric energy it would just stop working! As I had been on the road for 6.5 hours prior, I knew there was no electric reserve to pull from & said a prayer that my 4-yr-old daughter and I could get safely and get a tow to the dealership. The “reduced propulsion” message is part of a recall on the gen2 Volt, tho that recall relates to a software glitch & the remedy just provides “additional warning time” for this serious issue. My car just turned 5 years with 33,000 miles on it. I have followed all maintenance recommendations. Seems like an electrical emissions issue, & with a lithium battery on board, fire from overheating scares me as much as than engine failure on the interstate. But I had a full tank of gasoline! Dealer says it is a “short in my EGR Valve” & that part needs replacing.

When I start engine it says action required shift to park and it’s already in park. Then car won’t move. This has happened several times. Sometimes it will start but says vehicle propulsion is reduced and I drove it like this once and it was dangerous. This keeps happening and I am scared!

When shift-to-park the vehicle says the cars is not in park and will not turn off.

Car intermittently fails to shift from Drive to Park which means car can’t be turned off. Car intermittently fails to allow the fuel door to be opened which means it can’t be refueled.

IT IS AN ONGOING ISSUE AND THAT HAPPENS INTERMITTENTLY. WHEN ARRIVING TO A STOP (AT TIMES) THE CAR STILL ADVANCES FORWARD ABOUT A FOOT, EVEN WHEN THE BRAKE PEDAL IS BEING USED AS FAR AS IT CAN. ALSO THE VEHICLE CLAIMS TO BE LOSING PROPULSION, OFTEN, AND SEEMS STRAINED WHEN OPERATING WHEN THE MESSAGE APPEARS.

MY WIFE AND I WERE TAKING A 200 MILE TRIP. I WAS USING THE "HOLD" MODE, DRIVING AT 65 MPH, AND ABOUT 60 MILES INTO THE TRIP A MESSAGE CAME UP THAT I WAS IN REDUCED POWER MODE AND THE CHECK ENGINE LIGHT CAME ON. I PULLED OVER AND READ THE MANUAL AND THEN PROCEEDED ANOTHER 30 MILES USING THE ENGINE. I REDUCED MY SPEED TO 50 MPH. AFTER STOPPING FOR AN HOUR AT OUR DESTINATION, WE STARTED BACK HOME, BUT THE SAME ALERTS WERE ON THE SCREEN. I WENT TO A LOCAL CHEVROLET DEALER, 5 MILES. BEFORE GETTING THERE THE ENGINE SHUT OFF. I HAD 40 MILES OF BATTERY LEFT SO I PROCEEDED THE LAST 2 MILES TO THE DEALER ON BATTERY POWER. THEY COULD NOT SERVICE THE VEHICLE SO I HAD IT TOWED BY AAA 90 MILES TO TULSA. THE DAY BEFORE I LEFT I HAD RECEIVED THE MONTHLY DIAGNOSTIC REPORT WHICH STATED ALL SYSTEMS WERE FINE. THE CAR HAS 27,000 MILES ON IT. THE DEALER SAYS IT IS THE EGR VALVE, WHICH ARE BACK ORDERED. I DON'T KNOW WHEN IT WILL BE REPAIRED.

Mileage: 27,000

THE VEHICLE WILL NOT TURN OFF AFTER BEING PUT IN PARK. SHIFTING TO PARK SHOULD ALLOW THE VEHICLE TO BE TURNED OFF WITH THE START/STOP BUTTON. IT WILL NOT TURN OFF IN THE PARK POSITION.

PRIOR TO STARTING MY 1,100 MI TRIP WITH MY 2017 VOLT PREMIER, I INFLATED THE TIRES, CHECKED FLUIDS, & CHARGED THE CAR. THE MONTHLY DIAGNOSTIC REPORT I RECEIVED THE DAY BEFORE MY DEPARTURE INDICATED NO PROBLEMS WITH THE CAR, WHICH HAD APPROX 40,500 MI. I WAS DRIVING ON INTERSTATES & HIGHWAYS USING HOLD (GAS) MODE, OCCASIONALLY MOUNTAIN MODE. APPROXIMATELY 275 MI. INTO THE TRIP I RECEIVED POWER PROPULSION REDUCED ALERT. AFTER AN ADDITIONAL 50-75 MI I RECEIVED AN ACTION REQUIRED: ENGINE OVERHEATING REDUCE SPEED ALERT. I EXITED THE INTERSTATE AND PROCEEDED TO THE NEAREST DEALERSHIP TO DETERMINE IF IT WAS SAFE TO CONTINUE ON MY TRIP. I WAS TOLD THAT THE PROPULSION ALERT WAS NOT AN IMMEDIATE CONCERN & THAT THE OVERHEATING WAS LIKELY NOT RELATED. I ALSO RECEIVED A GM DIAGNOSTIC E-MAIL STATING THERE WAS AN EMISSIONS PROBLEM THAT SHOULD BE SERVICED WITHIN 7 DAYS, BUT DID NOT BECOME AWARE OF THIS E-MAIL UNTIL A DAY LATER. APPROX 200 MI LATER, I WAS ON A REMOTE, UNLIGHTED HIGHWAY WHEN I RECEIVED AN ENGINE UNAVAILABLE ALERT AND LOST POWER. MY CAR QUICKLY DECELERATED, BUT I WAS ABLE TO GET TO A NARROW SHOULDER. I TIRED TO PUT THE CAR IN PARK, APPLY EMERGENCY BRAKES, AND SHUT THE CAR DOWN BUT IT WAS DIFFICULT TO TELL IF THESE FEATURES WERE WORKING. I PUT THE HAZARD LIGHTS ON AND WAITED FOR A CHP OFFICER DUE TO LACK OF CELL SERVICE & HIGHWAY SAFETY CONCERNS AT NIGHT. AFTER 3 HOURS, ALL SYSTEMS FAILED, INCLUDING LIGHTS. ONLY MANUAL LOCKS WORKED. AFTER TWO 30 MI TOWS TO GET TO A DEALERSHIP WITH A VOLT TECH, IT WAS DETERMINED THAT A BAD EGR VALVE WAS CAUSING A FUSE TO BLOW,. THE VALVE WAS ORDERED (TECH REMARKED THAT THE PART IS "POPULAR") & INSTALLED. THE ISSUE SEEMS TO BE FIXED. BUT, IT IS UNCLEAR IF THIS IS A DESIGN FLAW, MANUFACTURING FLAW, OR A ONE TIME OCCURRENCE.

SHIFT TO PARK ISSUE. EVEN WHEN THE GEAR LEVER IS IN PARK POSITION AND TRYING TO SWITCH OFF THE POWER THE CAR STILL REQUEST TO MOVE TO PARK AND DOESN'T SWITCH OFF

PURCHASED A 2107 VOLT PREMIER WITH 40K MILES IN JULY 2020. MY WIFE WAS DRIVING THE CAR AND IT LOST POWER ON THE FREEWAY WITH A "SHIFT TO PARK" WARNING AND CHECK ENGINE LIGHT. SHE WAS ABLE TO GLIDE OVER TO THE SHOULDER AND I CAME TO RESCUE HER. AFTER REPEATED ON OFF CYCLES I GOT THE CAR TO MOVE A COUPLE OF MILES WITH SEVERAL "JERKING" MOTIONS WHILE DRIVING THEN IT DIED AGAIN AND I LOST POWER BRAKING (WENT TO MANUAL ONLY). THIS TIME I WAS UNABLE TO "RE-BOOT IT" AND HAD ONSTAR HAVE IT TOWED TO A LOCAL CHEVY DEALER WHO HAS A "CERTIFIED EV SPECIALIST"

AS I WAS DRIVING I RECEIVED A MESSAGE ON THE DRIVER INFO CENTER TO SHIFT IN PARK AND I LOST ACCELERATION WHILE DRIVING. PULLED OFF TO THE SHOULDER CONTACTED ONSTAR TO GET VEHICLE TOWED TO NEARBY DEALER. WAS PUSHED BY TWO POLICE OFFICERS TO GET OFF THE SIDE OF THE ROAD ON THE TWO LANE HIGHWAY. ONCE TOWED TO DEALERSHIP THE TOW DRIVER SAID I HAVE DRIVE AND REVERSE CAPABILITY AGAIN WHICH I DIDN'T HAVE WHILE PUT ON TOWER. AS I WAS STOPPED ON SIDE OF ROAD MY DRIVER INFO CENTER STATED PROPULSION POWER IS REDUCED SO I COULDN'T DRIVE OR REVERSE. CHECK ENGINE WAS ON THAT NIGHT AND THAT MORNING. AT THE DEALERSHIP, NO CODES COULD BE READ BECAUSE CHECK ENGINE LIGHT WENT AWAY.

VEHICLE WILL NOT TURN OFF WHILE IN PARK AND A 'SHIFT TO PARK' NOTICE IS DISPLAYED. VEHICLE NEEDS TO BE SHIFTED IN AND OUT OF PARK SEVERAL TIMES FOR IT TO REGISTER. HAPPENS INTERMITTENTLY. THE MANUFACTURER IS AWARE OF THE ISSUE AND HAS BULLETIN # 19-NA-206 ISSUED - A RECALL SHOULD BE MANDATORY AS THE VEHICLE CANNOT BE LEFT RUNNING UNATTENDED. IT IS A VIOLATION OF CALIFORNIA VEHICLE CODE 22515(A) NO PERSON DRIVING, OR IN CONTROL OF, OR IN CHARGE OF, A MOTOR VEHICLE SHALL PERMIT IT TO STAND ON ANY HIGHWAY UNATTENDED WITHOUT FIRST EFFECTIVELY SETTING THE BRAKES THEREON AND STOPPING THE MOTOR THEREOF.

WHEN MERGING ONTO THE HIGHWAY, I PRESSED THE ACCELERATOR, BUT THERE WAS A SIGNIFICANT LAG TO GET UP TO HIGHWAY SPEEDS. WITH THE WHEELS BEING POWERED BY THE ELECTRIC ENGINE, THE RESPONSE HAD ALWAYS BEEN INSTANT, UNTIL TODAY. AFTER ARRIVING AT MY DESTINATION, I TURNED MY CAR OFF AND BACK ON, BUT THE CHECK ENGINE LIGHT CAME ON AND THE DASH READ "SHIFT TO PARK," EVEN THOUGH THE CAR WAS IN PARK.I TURNED THE CAR OFF AND ON AGAIN, AND THIS TIME I WAS ABLE TO SHIFT THE CAR TO DRIVE, BUT THE CHECK ENGINE LIGHT REMAINED ON. THE ACCELERATOR DID NOT PROPEL THE CAR AND THE STEERING WHEEL WAS LOCKED. I AGAIN SHIFTED TO PARK AND TURNED OFF THE CAR. I WAITED A FEW MINUTES AND STARTED THE CAR BACK UP, AND THE FUEL ENGINE TURNED ON THIS TIME, BUT I RECEIVED A MESSAGE SAYING THE CAR WAS NOT CHARGING. I WAS ABLE TO DRIVE IT, BUT THE ENGINE WOULD NOT SHUT OFF, AS IT USUALLY DOES AFTER THE BATTERIES ARE SUFFICIENTLY CHARGED. I DROVE ABOUT 3 MILES ON SURFACE STREETS AND THE FUEL ENGINE REMAINED ON THE ENTIRE TIME. THERE WAS A SIGNIFICANT AMOUNT OF LAG IN RESPONSE TIME BETWEEN PRESSING THE ACCELERATOR AND THE BATTERIES CHARGING UP ENOUGH TO PROPEL THE CAR, CAUSING AN UNSAFE RESPONSE TIME IN MERELY GETTING THE VEHICLE GOING AFTER STOPPING AT A LIGHT AND TURNING ONTO A NEW STREET.

FOR THE PROPULSION MANY TIMES WHILE DRIVING IT OCCASIONALLY SLOWS DOWN OR SPEEDS UP KIND OF LIKE A BUCKING HORSE. FOR THE ELECTRICAL THE BLUETOOTH CONNECTIVITY TO MY CELL PHONE AND ALSO MY FOB OFTEN DISCONNECT AND THEN I CAN'T LOCK OR UNLOCK MY CAR. FOR THE OTHER ISSUE I HAVE A SHIFT TO PARK PROBLEM THAT LOCKS MY CAR AND I CAN'T SWITCH GEARS OR TURN THE CAR ON OR OFF FOR A FEW MINUTES THEN IT ALL OF A SUDDEN TURNS BACK ON BUT THE ISSUE IS THAT WHEN IT SAYS SHIFT TO PARK IT IS ACTUALLY IN THE PARK POSITION. *TR

I PURCHASED MY USED 17 CHEVY VOLT 2 MONTHS AGO. SUDDENLY MY CAR STARTED HAVING INTERMEDIATE ISSUES OF SHOWING "SHIFT TO PARK" WHEN THE VEHICLE IS CLEARLY IN PARK MODE. WHEN THIS OCCURS THE VEHICLE CANNOT BE SHUT OFF. I HAVE ATTEMPTED TO CONTACT GM BUT THEY CLAIM THERE ARE NO RECALL OR SERVICE BULLETINS FOR MY VIN/VEHICLE. THERE ARE COUNTLESS ONLINE COMPLAINTS FROM 17 VOLT OWNERS SHOWING THE SAME ISSUE (THIS IS ALSO OCCURRING WITH OTHER GM MODELS & I AM ALSO SEEING SIMILAR COMPLAINTS ON THIS SITE). GM IS FULLY AWARE OF THIS DEFECT & HAS ONLY ISSUED SERVICE BULLETINS ON SOME VIN # - WHILE THEY SHOULD HAVE CAUSE - BASED ON NUMEROUS COMPLAINTS - THAT THIS IMPACT IS OCCURRING WITH THE MAJORITY OF 17 VOLTS. THIS IS A SAFETY ISSUE WHEN A 3,794 LBS VEHICLE CANNOT BE SHUT OFF. I AM ASKING THAT NHTSA ISSUE A RECALL IN REGARDS TO 2017 CHEVY VOLTS & THE "SHIT TO PARK" ISSUE. WHILE THIS IS AN INTERMEDIATE ISSUE AND SOME DAYS MY CAR SHUTS OF FINE WHILE OTHERS IT TAKES MOVING THE SHIFTER BACK BETWEEN GEARS IN ORDER FOR THE ELECTRICAL COMPONENT TO RECOGNIZE IT'S PARKED - I WILL TRY TO CONTACT MY LOCAL DEALER FOR HELP BUT I AM FILING THIS COMPLAINT TO PUT GM & NHTSA ON NOTICE REGARDING THIS WELL KNOWN DEFECT THAT IS NOT BEING ADDRESSED AND COULD BE A SERIOUS SAFETY ISSUE. GM SHOULD DO THE RIGHT THING AND ADDRESS THIS ISSUE WHICH IS WELL DOCUMENTED - BY PROVIDING A RECALL.

WHILE DRIVING ON A BUSY SURFACE STREET THE VEHICLE LOST ALL PROPULSION AND STALLED. STEERING LOCKED UP, WAS DISABLED, AND ELECTRIC POWER STOPPED. THE WARNING LIGHT READ "ACTION REQUIRED - SHIFT TO PARK'. THIS STALL IS IMMEDIATE AND HIGHLY DANGEROUS. I WAS ABLE TO GLIDE TO THE SIDE OF THE ROAD WITHOUT BEING IN OR CAUSING AN ACCIDENT. THE ORANGE ENGINE SYMBOL WAS ILLUMINATED. ALL SYSTEMS SHUT DOWN ON THE VEHICLE. THE CAR WAS TOWED TO THE NEAREST CHEVY DEALERSHIP BUT WE WERE UNABLE TO TURN OFF THE VEHICLE OR SHIFT IT IN NEUTRAL. THE CAR START BUTTON WOULD NOT TURN OFF THE VEHICLE AND HAD TO BE TOWED RUNNING AND THE BATTERY DISABLED AT THE DEALERSHIP.

Mileage: 18,881

WHILE ENTERING THE HIGHWAY THE VEHICLE EXPERIENCED SIGNIFICANT LOSS OF PROPULSION AND THE WARNING DISPLAYED "PROPULSION POWER REDUCED".THIS LOSS OF POWER OCCURRED WHEN THE VEHICLE SWITCHED FROM ELECTRIC TO GAS POWER. I HAVE EXPERIENCED ISSUES WITH THE VEHICLE SWITCHING FROM ELECTRIC TO GAS REGULARLY AND IT SPUTTERS AND BUCKS. AFTER A FEW MILES THE SPUTTERING AND ROUGH CHANGE TO GAS WILL DISSIPATE. ON THIS OCCASION THE POWER LOSS WAS SIGNIFICANT AND DANGEROUS. I WOULD NOT HAVE HAD THE POWER OR PROPULSION TO ENTER THE HIGHWAY. I WAS ABLE TO DIVERT TO CITY STREETS AND GET HOME AT SPEEDS UNDER 40 MPH. THE VEHICLE WOULD NOT GO ANY FASTER. THE VEHICLE WAS SERVICED BY MY LOCAL CHEVY DEALER AND OUT OF SERVICE FOR 18 DAYS WITH APPROXIMATELY 250 MILES OF ROAD TESTING WHILE IN SERVICE. I NO LONGER BELIEVE THIS VEHICLE TO BE SAFE OR RELIABLE AND AM ENGAGED IN ARBITRATION UNDER THE CALIFORNIA LEMON LAW AND THE BBB.

ON MY 2ND DAY OF OWNERSHIP WHEN THE VEHICLE HAD 50 MILES ON IT THE VEHICLE STOPPED WITHOUT WARNING IN THE MIDDLE OF THE HIGHWAY. WHILE DRIVING 65 MPH ON INTERSTATE 5 (4 LANE HIGHWAY) THE VEHICLE BEGAN SMOKING AND LOST ALL PROPULSION AND FORWARD POWER. THE VEHICLE HAD JUST CHANGED FROM ELECTRIC POWER TO GAS POWER. THE WARNING MESSAGE DISPLAYED WAS "ACTION REQUIRED - SHIFT TO PARK". THE ORANGE ENGINE SYMBOL WAS DISPLAYED. THEN THE STEERING WHEEL LOCKED UP, ALL DISPLAYS AND CONTROLS WERE TURNED OFF. LUCKILY I WAS ABLE TO MOVE FROM THE 2ND TO FAR RIGHT LANE OF 4 AND GET JUST OFF THE HIGHWAY. THERE WAS JUST ENOUGH SPACE TO GLIDE THE VEHICLE TO A STOP OFF THE HIGHWAY. HOWEVER, THE I5 IS THE PRIMARY TRUCKING ROUTE AND IN THIS UPHILL LOCATION ALL SEMI TRUCKS ARE REQUIRED TO DRIVE IN THE FAR RIGHT LANE. MY VEHICLE WAS SWAYED CONTINUOUSLY BY THE LARGE HIGH PROFILE VEHICLES FOR OVER 2 HOURS. A CHP STAYED WITH ME WITH FLASHING LIGHTS TO ATTEMPT TO MOVE VEHICLES TO THE LEFT. THE VEHICLE WAS TOWED TO THE NEAREST DEALERSHIP. THE VEHICLE WAS REPLACED BY THE DEALERSHIP WITH ANOTHER VEHICLE AFTER 9 HOURS. HOWEVER, I AM NOW IN ARBITRATION WITH GM OVER THE SAME ISSUE "ACTION REQUIRED - SHIFT TO PARK" WITH THE 2ND VEHICLE. THE VEHICLE HAS BEEN IN SERVICE FOR 95 DAYS OVER AN 8 MONTH PERIOD AND I AM SEEKING A VEHICLE BUYBACK UNDER THE CALIFORNIA LEMON LAW WITH THE BBB FOR IMPAIRMENT OF VALUE, USE, AND SAFELY.

THE TROUBLE BEGAN ON MARCH 16TH, I CAME TO A STOP AT A LIGHT, READY TO TAKE A U TURN.DRIVING IN EV MODE. ALL LIGHTS IN THE CONSOLE TURNED ON AND I GOT THREE ERRORS "INFORMATION : PROPULSION POWER IS REDUCED" "SERVICE : STABILITRAK" "SERVICE : POWER STEERING. DRIVE WITH CARE" THE POWER STEERING GAVE UP.RESTARTED THE CAR AFTER 5MINS, EVERYTHING WAS NORMAL. ON MARCH 24TH, ON A HIGHWAY , IN HOLD MODE. AFTER A FEW MILES IN, I GOT AN ERROR "ACTION REQUIRED: ENGINE OVERHEATING REDUCE SPEED" TOOK THE NEXT EXIT OUT AND SAW THAT THE COOLANT TANK IS EMPTY. TURNED ON EV MODE , DROVE BACK HOME. ON MARCH 25TH MORNING, TOOK THE CAR IN TO SERVICE CENTER (DRIVE-IN). THEY IDENTIFIED A VALVE LEAKING IN THE COOLANT LOOP. REPLACED THE PART. MULTI-POINT INSPECTION DONE. 2 PENDING RECALLS DONE.

WHEN VEHICLE RUNS OUT OF GAS AND ONLY HAS BATTERY POWER (NO MATTER THE CHARGE) THE CAR GOES INTO REDUCED POWER MODE WHICH IS DANGEROUS IN ANY TRAFFIC ESPECIALLY INTERSTATE HIGHWAYS!!! THIS HAPPENS EVERY TIME YOU RUN OF GAS!! ALSO THE ADAPTIVE CRUISE NOT WORKING ALL THE TIME AND DISENGAGES BY ITS SELF FOR NO REASON(LIKE NOTHING IN FRONT OF YOU)!!

LIKE OTHERS, INCLUDING THE INCIDENT IN RANCHO CUCOMONGA, CA ON THE SAME DAY, APRIL 25TH, I WAS DRIVING ON THE HIGHWAY AT HIGH SPEED. I WAS IN THE CARPOOL LANE ON THE 210 FREEWAY. I THINK I ALSO WAS TOLD TO PUT THE CAR IN PARK. I LOST THE ABILITY TO ACCELERATE ON AT A VERY DANGEROUS TIME, WHILE I WAS THE FURTHEST TO THE LEFT IN THE LATE AFTERNOON. MIRACULOUSLY, THERE WAS ONLY 1 CAR QUITE FAR BEHIND ME. SO, AFTER DECELERATION WAS FORCED UPON MY CAR, I BEGAN TO STEER THE CAR TO THE RIGHT THROUGH 5 LANES - ONE OF THE WIDEST PARTS OF THE HIGHWAY AT THAT POINT. HERE IS WHAT I NOW THINK. I HAVE BEEN THROUGH LOSS OF POWER IN MY 2014 VOLT. I HAD ACCIDENTALLY TURNED IT OFF WHILE BEING ON THE HIGHWAY. THEY FIXED THAT DESIGN FLAW IN THIS 2017 MODEL. I HAVE SHARED MY THEORY WITH GM. GM/CHEVY HAS 3-WAY CALLED ME WITH THE "STOLEN VEHICLES DEPT". THEY AGGRESSIVELY DESCRIBE HOW THEY WON'T ISSUE A SLOW-DOWN THROUGH THE ON-STAR UNLESS THEY HAVE A REQUEST THROUGH POLICE, THE POLICE ARE BEHIND, THE LIGHTS BLINK, ETC. BUT, THEY'RE RELUCTANT TO SHARE WHAT HAPPENS NEXT. THEY'VE BEEN RELUCTANT TO SHARE HOW THEY TRACK YOUR VEHICLE THROUGH THE VIN AND GPS TRACKING. THEY'RE RELUCTANT TO SHARE THAT THIS SYSTEM CAN BE HACKED. IT IS EVIDENT THAT MUCH CAN GO WRONG ONCE THE ABILITY TO CONTROL YOUR CAR IS PLACED IN OTHER'S HANDS -- WHO AREN'T IN THE CAR DRIVING IT. THE DEALERSHIP COULD SEE THE CODE OF THE SLOW-DOWN. OF COURSE THEY WERE SURPRISED. THIS WASN'T JUST A "FAILURE". THIS IS A "FEATURE" IN THE CAR...BUT SOMEONE ELSE USED IT WITHOUT OUR PERMISSION. I WANT THE ON-STAR CONTROL DISABLED IN MY CAR!!! IT COULD HAVE KILLED MY DAUGHTER AND ME. IT COULD HAVE KILLED THE OTHERS WHO REPORTED A SIMILAR SITUATION.

URGENT URGENT. THIS IS SOMETHING WRONG WITH THE 2017 VOLT. MY VEHICLE CAUGHT ON FIRE WHILE DRIVING DOWN THE INTERSTATE AT HIGHER SPEEDS. I HAVE FOUND TWO OTHERS THAT THIS HAS HAPPENED TOO. GM DIDN'T EVEN INVESTIGATE BEFORE DENYING LIABILITY, THEY MADE A DETERMINATION OVER PHOTOS. ALL 3 VEHICLES HAD OVER 20K MILES ON IT. OTHERS LIVES MAY BE IN DANGER. PLEASE INVESTIGATE.

I WAS DRIVING ON FREEWAY AT 65 MPH THEN ALL THE SUDDEN I GOT CHECK ENGINE LIGHT ONE AND MESSAGE "ACTION REQUIRED, SHIFT TO PARK", I NOTICED THE DOOR UNLOCKED BY ITSELF AND THE CAR STARTING TO LOSE PROPULSION, I GLIDED OFF THE FREEWAY AND STOPPED AT THE END OF OFF RAMP DUE TO RED TRAFFIC LIGHT, THEN THE CAR CAN NOT START AGAIN. AFTER TOW TRUCK CAME, THE CAR STARTED AGAIN AND I WAS ABLE TO DRIVE TO DEALER FOR REPAIR. DEALER FOUND TWO ERROR CODES IN THE HISTORY P0AC4 AND P0604. ALTHOUGH THE CAR IS WORKING FINE AT THIS MOMENT AND SEEMS LIKE IT WAS JUST SOME SORT OF COMPUTER CRASH, HOWEVER IT WAS VERY DANGEROUS TO LOSE PROPULSION ON THE FREEWAY AND STUCK ON A HEAVY TRAFFIC OFF RAMP.

Mileage: 17,850

WE'VE HAD A TOTAL OF THREE CHEVY VOLTS. TWO HAVE BEEN GREAT, BUT THE 2017 VOLT WE GOT IN FEBRUARY 2017 HAS BEEN AWFUL -- THE CAR COMPLETELY LOSES POWER WITHOUT WARNING. IT HAPPENS WHILE DRIVING, BOTH ON THE FREEWAY AND SURFACE STREETS. AND JUST TO CLARIFY, I DON'T MEAN THE CAR WAS OUT OF ELECTRICITY OR OUT OF GAS (EACH TIME THIS HAPPENED, THE CAR HAD BOTH). WE WILL BE DRIVING ALONG WHEN, OUT OF THE BLUE, THE CAR SIMPLY JUST STOPS RUNNING, LEAVING US TO DO OUR BEST TO GET IT OUT OF THE ROADWAY WITHOUT GETTING HIT. THE CAR (WHICH ONLY HAS ABOUT 1,000 MILES ON IT) HAS BEEN IN THE SHOP OFF AND ON FOR ABOUT A MONTH NOW. WE HAVE BEEN VERY DISAPPOINTED BY HOW BOTH GM AND THE DEALER HAVE BEEN HANDLING THE SITUATION.

Mileage: 1,000

STRONG BURNING AND/OR FUEL SMELL FILLED THE PASSENGER CABIN. THIS HAS HAPPENED ON SEVERAL OCCASIONS MOST NOTABLY WHEN THE CAR WAS OPERATING IN 'ENGINE RUNNING DUE TO TEMPERATURE' MODE. THE ODOR WAS STRONG ENOUGH TO CAUSE DIZZINESS AND REQUIRED TO THE WINDOWS TO BE OPENED TO VENT THE CABIN. THE SMELL AND ORDER NOW IS PERSISTENT EVEN WHEN DRIVING IN ALL-ELECTRIC MODE. MY INTENSION IS TO REPLACE THE CABIN AIR FILTER WITH A CARBON AIR FILTER PER 16-NA-127.

MY 2017 CHEVY VOLT SUDDENLY LOST ALL POWER WHILE I WAS DRIVING ABOUT 35 MPH IN ELECTRIC MODE. THE CAR HAS BEEN DRIVEN ABOUT 4500 MILES. A "SHIFT TO PARK" MESSAGE WAS DISPLAYED ON THE DASHBOARD. I COULD NOT RESTART THE CAR AND HAD IT TOWED TO A DEALER FOR SERVICE. THE DEALER REPLACED THE POWER INVERTER MODULE AND UPDATED THE SOFTWARE. AFTER THE REPAIRS, THE ELECTRIC MOTOR HAS STALLED ON TWO OCCASIONS AND THE CAR SHAKES VIOLENTLY THEN SWITCHES INTO THE GASOLINE ENGINE MODE.

Mileage: 4,500

ON 3 SEPARATE OCCASION MY CAR HAS DIED ON THE HIGHWAY AND LOST ACCELERATION, GM ISSUED A RECALL BETWEEN MY FIRST AND SECOND INCIDENTS AND THE RECALL FIX DID NOT FIX THE ISSUE AS THIS HAPPENED A THIRD TIME. NOV 14TH WAS THE FIRST TIME BUT IT HAS HAPPENED MULTIPLE TIMES. THIS IS VERY DANGEROUS AND PEOPLE WILL PROBABLY DIE BECAUSE OF THIS. THE ERROR MESSAGE ON THE SCREEN IS PROPULSION POWER IS REDUCED

WE ARE WRITING TO VOICE A VERY DISCONCERTING AND DANGEROUS INCIDENT WITH OUR 2017 CHEVY VOLT. ON A RETURN TRIP AT DARK FROM CLEVELAND, OHIO TO ROCHESTER, NY ON 12-26-16, OUR ENGINE SUDDENLY GAVE WARNING BEEPS WHICH PROMPTED MY HUSBAND TO PULL OVER TO THE SHOULDER ON INTERSTATE 90 IN ERIE, PA. WE HAD ALL OF 15-20 SECONDS TO GET OFF THIS HEAVILY TRAFFICKED HIGHWAY WHEN THE CAR LITERALLY SHUT DOWN.. NOTHING WORKED NOT EVEN THE WARNING FLASHERS. WE COULD NOT OPEN THE TRUNK, AND HAD WE NOT KEPT ONE DOOR OPEN WE WOULD NOT HAVE BEEN ABLE TO ENTER THE CAR. IN SUMMARY, THE TOTAL FAILURE WE ENCOUNTERED SHOWS THE SERIOUS SAFETY ISSUE RELATED TO THIS CAR. WE ARE NOW RELUCTANT TO TAKE IT ON TRIPS THIS INCIDENT COULD HAVE RESULTED IN A SERIOUS ACCIDENT HAD WE NOT BEEN ABLE TO PULL OFF ONTO THE SHOULDER.

THE VEHICLE CENTER DISPLAY DOES NOT WORK RELIABLY. MOST CONCERNING TO SAFETY IS THE FACT THAT THIS RENDERS THE REVERSE CAMERA INOPERABLE. OTHER THINGS THAT DON'T WORK INCLUDE BLUETOOTH, RADIO, ON STAR, CONTROLS FOR THE VEHICLE SETUP AND CHARGING PARAMETERS, AIR CONDITIONING, ENERGY USAGE DISPLAY, AND SO ON. AFTER SEVERAL SERVICE VISITS AND CALLS TO GM, THEY DETERMINED THAT IF YOU LEAVE A PHONE PLUGGED INTO THE USB CORD FOR THE AUDIO SYSTEM, AND POWER THE CAR OFF WITHOUT FIRST UNPLUGGING THE PHONE FROM THE CHARGER AND EVEN THE CHARGER CORD FROM THE USB PORT (WITH NO PHONE PLUGGED IN) OR ELSE THE NEXT TIME YOU START THE CAR THE SCREEN AND FUNCTIONS ON IT WILL BE INOPERABLE UNTIL THE CAR IS POWERED OFF FOR SEVERAL MINUTES. WHETHER OR NOT I UNPLUG MY PHONE WHEN I TURN OFF THE CAR SHOULD PREVENT THE BACKUP CAMERA FROM FUNCTIONING NOR THE DETAILS ABOUT ELECTRIC CAR CHARGE USAGE. GM HAS TOLD ME THERE IS NOTHING MORE THEY CAN DO, THAT'S JUST HOW IT WORKS.

I WAS DRIVING MY 2 MONTH OLD CAR WITH ~2300 MILES ON A BUSY HIGHWAY AT ~ 65 MPH WHEN SUDDENLY THE CAR LOSES POWER AND THE PANEL READS "SHIFT TO PARK". LUCKILY, I WAS ABLE TO MANEUVER THE CAR (STEERING WAS STILL IN TACT) WITH THE REMAINING SPEED TO THE SIDE OF THE HIGHWAY. HOWEVER, HAD THE HIGHWAY BEEN BUSIER OR IF I HAD BEEN ON THE FAR LEFT LANE, I DON'T THINK I WOULD HAVE BEEN ABLE TO MAKE IT AND WOULD HAVE CREATED A DANGEROUS SITUATION ON THE HIGHWAY. ON THE VOLT FORUM, OTHERS HAVE ALSO COMPLAINED ABOUT THIS. THE REPAIR, THOUGH COVERED, TOOK 3+ WEEKS AT THE DEALERSHIP. FROM DEALER PRINTOUT "INTERNAL TRANSMISSION PRIME NOTOR(SIC) INTERNAL FAILURE P03AF DRIVE MOTOR REMOVE AND REPLACE WITH SRTA SRTA UNIT".
