2017 CHEVROLET VOLT Engine Problems

EGR valve and EGR cooler failure. Engine power was reduced and EGR fuse kept blowing. Has code for EGR flow failure/restriction. Check engine light remains on even when reset

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.

Thousands of 2014-2017 Chevy Volt owners are having issues where the EGR Valve malfunctions and the engine shuts down. The Volt's EGR valve can cause the car to shut down by blowing the "walk home" fuse. This is a safety issue. In many cases cars are in the shop for months because the part is on "backorder". That's my situation-- dealer just told me it's a $2800 repair job, but the part is on "backorder". The car only has 49K miles.

My 2017 Chevrolet Volt is experiencing "a malfunction involving the battery energy control module (BECM)" as diagnosed by the Davis-Moore dealership. This failure of the BECM has now caused "a reduced power mode, a no start condition, or a no charge condition". The car currently does not start or charge. My vehicle has be diagnosed as needing a BECM replacement at a Chevrolet dealership. The vehicle is currently inoperable as it will not charge, it will not engage the electric drive mode, and it will not engage the range extender (engine). The car does not start. GM is showing that there is no active recall or special warranty for my vehicle, however, I believe special warranty N23243268 should apply.

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.

EGR Valve stop functioning, which caused Service not available engine check light on. This is a hybrid plugin, when battery is low, it is dangerous is Gas Engine not functioning. This EGR Valve is super expensive, the fix (Parts and Labor) is over $3300. The car milage was only a little over 58800 miles. Without getting this repaired, the emission inspection will not be passed in Virginia.

My experience required me to tow my 2017 Chevy Volt from a parking garage, where the BECM died, to 2 different dealerships back and forth to my home. I have been charged over $1,000 in towing and diagnostics at my local dealerships. As usual they informed that I need a new $10k battery. I did my own research and the error codes (U2603, U2604, U2605, U2606, U2617, U2618, U2619, U2620, U2621, U2622, U2623, U2624 and P1E00) clearly indicate that my BECM failed. I was able to check the health and status of the traction battery and it functioning correctly. On my 3rd trip to my local dealership service department with the Special Coverage Program N232432680 in hand, the dealership informed me that yes my BCM had failed and there was a Special Coverage Program for 2016-2019 Chevy Volts, but that MY VIN NUMBER WAS NOT COVERED. There were a limited number of VINS that received warranty extensions for BECM, but mine was not.

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

My 2017 Volt reported a "Propulsion Power is Reduced" message on the display. When I took the car to the dealership for service, they stated that a new EGR valve was needed. The part alone is $1847. The total service with labor would have been over $3000. Looking online, it is a very common issue for the gen 2 Volts. Unfortunately, the dealership is saying this repair is not covered under warranty.

There is a part that fails on a lot of GM vehicles due to getting clogged (an EGR valve). It prevents the vehicle from reaching high speeds on the highway and can fail while driving (which happened to me). I could have lost control of the vehicle on the highway and crashed or gotten rear-ended. GM refuses to pay for repairs involving this part despite so many people reporting the issue that they needed to do another production run of the part after discontinuing it. Here are many others that experienced this problem: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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?

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

Bad EGR valve in 2017 Chevy Volt, apparently a common problem. Received a check engine light, risk of reduced propulsion (creates risk of stalling and crashing on highway).

P0401 ERROR EGR VALVE NOT RECEIVING ENOUGH FUEL

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.

Battery Energy Control Module failed and left my daughter stranded.

Yes this vehicle can be made ready for inspection upon request. According to the registered Chevrolet dealership who inspected my vehicle and gave me the diagnosis - The cars EGR valve control board is shorting out Fuse #3 which leads the car to enter “reduced propulsion mode” and keeps you from using the generator engine due to being in this mode. This happened as I was driving home from work one day and the car notified me of this issue and entering into this mode. This could leave people stranded if low on battery charge, or in danger due to reduced propulsion. Chevy no longer manufactures this unique EGR valve and thus the repair requires obtaining back ordered parts from a manufacturer outside of the US for thousands of dollars. Alternatively you can drive without the EGR power cord connected, which means greater emissions and environmental risk/damage. This is not covered under warranty. This is a known faulty part that many Volt owners complain about, which makes it a good candidate for recall.

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 car has a Check Engine Light and "reduced propulsion" warning. Based on OBDII errors, the EGR on my chevy volt failed. I am not in a CARB state (i'm in Hawaii, though I bought my Volt in CA, which is a CARB state). The EGR issues plague all Gen2 Chevy Volts, and tends to break around 40-70k miles into the life of the car. EGR spare part availability is very limited. Given the frequency with which this car breaks for this issue, and the negative impact on emissions, this should be a recall issue nationwide, not just for states that keep CARB requirements.

The contact owns a 2017 Chevrolet Volt. The contact stated that while attempting to start the vehicle, the vehicle failed to start. The contact stated that the message “Unable to Charge” was displayed with the check engine warning light illuminated. The local dealer was contacted; however, the vehicle was not diagnosed. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 115,000.

Mileage: 115,000

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!!

My car's check engine light went on and after a while started blinking. The car would not go. When I got it towed and checked by the dealership, they said my EGR Valve had an issue and needed to be replaced. They said the part was on backorder and it could take months and tried to charge me $2,000 up front to "reserve the part." It seems like GM has deprioritized this part and is putting drivers like myself at risk of not being able to use our cars and not being able to pass emissions inspections required in my state. This was originally diagnosed in spring 2024 and I have been unable to get a replacement as of January 2025

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.

Vehicle went to low power mode on the interstate (I4) and was unable to drive at normal safe speeds. Engine overheated and would not allow vehicle to drive over about 10 mph, had to drive slowly on interstate until I could pull off safely to let it cool and get towed home. Technicians verified it is the known EGR valve issue, which happens often and isnt covered under any warranty. From research online this is a common problem that strands people in Volts and GM wont fix and cant even get more parts for to repair vehicle. Can leave people with sudden power loss while driving and limit driving speeds to unsafe levels unexpectedly.

The EGR valve failed and has been on order for over 6 months. I unplugged it to keep the car operational, but it will not pass an environmental inspection without a new valve. THIS IS A VERY COMMON COMPLAINT ON ONLINE FORUMS. Something needs to happen to force GM to resolve this issue.

While operating my Chevy Volt on a Los Angeles Freeway, warning lights came on informing me to park immediately, and that the power propulsion was reduced. The Check Engine light also came on. At that point the “Shift to Park” message came on. My car is experiencing the “Shift to Park” issue. I already had this happen previously in 2023. The repair cost $1,200. There are many, many references to this issue on the Internet. The “Shift to Park” defect is well known in the Chevy Volt community. When this happened the SECOND time, ([XXX]), I was stranded on the side of an LA freeway. The car will not start. It will cycle through the “Shift to Park” message on the dashboard and it will not go anywhere. The car initializes, so there is power in the vehicle, but no propulsion.

In what appears to be (based on Google search) hundreds of Volts have the failure whereby the ERG valve fails, but GM is no longer making the part and has an indefinite date to produce them. When this part fails the engine light comes on the the vehicle is not allowed to go over 45 MPH, creating a safety issue when on highways (I live rural, all all roads are over >=55 MPH). GM is unwilling to trade the car at fair value for a new one, nor willing to provide loaners. So the car can only sit in the garage with no resolution. GM is aware of the issue, nut is unwilling to address.

Just purchased and not a week in it dies after I have charged it. I was in drive, at a red light when all of a sudden the car dies. No warning whatsoever. Was not able to turn it on afterwards. Had to get towed to my local Chevrolet dealership that has not been able to fix it for the last month with no ETA on a fix.

On July 21st, 2024, the Exhaust Gas Recirculation (EGR) valve failed. It blows the “Non Walk Home” F03 fuse, resulting in the check engine light and a “Propulsion Power is Reduced” warning message. The vehicle is not to be driven in this condition. The EGR valve is included in the Emission Warranty Parts List and the PZEV Emission Control System Defect Warranty (15yr/150,000mi) is active on the vehicle. The vehicle has been to two Chevrolet service centers, Mission Bay Chevrolet on July 22nd and Kearny Mesa Chevrolet on August 6th without successful repair. They explain that the EGR valve part is on backorder and have no estimate for its availability. The vehicle has been at the Kearny Mesa Chevrolet service department for 55 days. Having the vehicle suddenly and unexpectedly enter a diminished propulsion mode at freeway speeds is unsafe.

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.

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.

I was driving on the interstate when my check engine light came on and the car told me it was going into reduced power mode. I then had to limp my car along on the interstate till I could get off the road, many close calls going 45-50 mph on a 70 mph road.

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.

Received the vehicle on 8/6/24 with 96,500 miles on it. On 8/15/25 I received a check engine light with error code P0401 indicating an issue with the EGR Valve. I took the vehicle to my dealership which confirmed the issue and was informed that it was a common failure with this type of vehicle. I was placed on a waitlist for the part which as of today, 9/9/24, still is not available. A quick Google search shows that that this error is extremely common for these vehicles.

Component or System Malfunction: The Exhaust Gas Recirculation (EGR) valve in my Chevy Volt failed, causing a complete loss of vehicle power and potentially leading to engine overheating. This malfunction has been widely reported among other Chevy Volt owners, and the EGR valve has been improperly designed. The part is not available for replacement, making it impossible to fix the issue, even though Chevy lists the cost at $3,000 to $4,000. See [XXX] as a sampling of people experiencing the problem. Safety Risks: The failure of the EGR valve puts both my safety and the safety of others at serious risk, as the sudden loss of power could result in accidents, especially when driving at higher speeds or in heavy traffic. Additionally, the potential for engine overheating increases the risk of further damage or even fire. Problem Confirmation: This problem has been reproduced and confirmed by my local dealer, who informed me that replacement parts have been back-ordered since April, with no estimated delivery date available. Many other customers are experiencing the same issue and have also been unable to obtain the necessary parts. Inspections: The vehicle has been inspected by the dealership, but no solution has been provided due to the lack of available replacement parts from the manufacturer. The manufacturer has not offered a viable timeline or alternative resolution. Warning Signs: Prior to the failure, I experienced warning lights related to engine performance. These warning messages first appeared in April, signaling an issue with the EGR valve. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

CEL came on in January 2024. Brought to dealer and diagnosed with failed EGR valve. EGR valve replacement part is not available from manufacturer. No information on when EGR valve might be available has been offered from dealer or manufacturer. Valve must be replaced to pass emissions inspection in December.

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.

Purchased the '17 Chevy Volt for my Daughter on [XXX] with 58,867 miles. On [XXX], 60,600 miles; She was driving on the interstate when the engine temperature spiked, followed by a check engine light and a warning message: "Engine unavailable." The vehicle suddenly lost power when she reduced pressure on the accelerator, causing a rapid reduction in speed. nearly causing her to lose control. The vehicle's OBD Codes were scanned at a nearby auto parts store resulting in 30 DTC appearing. I found hundreds of complaints and posts about the F3UA fuse blown and a faulty EGR valve. A service bulletin for this issue was published by GM in Feb 2023. I notified the dealership of the issues and the vehicle was brought to Deacon Jones Chevy of Clinton, NC on July 16th. The service department informed me that the 12V Battery was bad and needed replacement to "correct" the issue, at a cost nearly $550. I asked if the fuse mentioned was blown and was informed that it was not. The check engine light was cleared and my daughter drove home. Before getting home, the check engine light came back on, the temperature spiked, and "propulsion power is reduced." message appeared. This was accompanied again by a rapid reduction in speed nearly causing a collision. I called the dealership back and informed them of the incident. They requested to have the vehicle brought back to the shop, however, towing was out of the question because the dealership is 70 miles from me & I did not want to drive the car in its condition. I took the vehicle to Team Chevy in Swansboro, NC, who ran proper diagnostics. I was informed the F3UA fuse was blown, caused by a short in the EGR Valve. The original dealer offered to split the cost, but Team Chevy said they could get the part & match price. When ordered, it showed the EGR Valve was backorder with no ETA. 6 weeks in and no safe transportation for my daughter and grandson. Significant safety issue with no replacement parts or accountability, ludicrous. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFOR

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.

The vehicle was restarted; however, the failure recurred. The vehicle was taken to an independent mechanic where it was diagnosed and determined that the EGR valve had failed and needed to be replaced. The vehicle was not repaired. The dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 80,000.

While driving my 2017 Chevy Volt on the highway, a “Propulsion power is reduced” message appeared accompanied by the CEL. Prior to this there had been no indication that anything was wrong. The warning was quite vague and it wasn’t at all clear what it actually meant so I continued driving. Shortly after this, I began to notice a bit of a “chuggle” or lurching sensation (particularly on hills). This made the acceleration slightly unpredictable, and at one point even triggered the forward collision warning when the car accelerated a bit after I took my foot off the gas pedal (coming up behind another car at a traffic light). I pulled over and attempted to figure out what the issue was. I had a notice regarding the BECM recall in my glove box which listed a reduced power mode as a potential symptom, so I scheduled a service appointment (figuring it was that) and continued my trip. I stopped to get gas, then a mile or two down the road the engine overheated and shut off. By sheer luck I had a few miles of range left in electric mode which allowed me to pull over safely, but I was now stranded over 100 miles from home. I managed to get the vehicle to a dealership in Danvers, MA where they diagnosed the problem as a failed EGR valve. My understanding is this is related to a defect in the valve electronics.The valve failed and blew the F3 fuse, which also supplies power to the engine cooling system. It doesn’t take long for the engine to overheat and it seems this can lead to a complete loss of power while driving when the electric range is already depleted. The valve is currently unplugged while I await a replacement but there is no word on how long that might be. Other Volt owners have had to wait months or even years to get a new valve. The repair quote I received is also unreasonably expensive (> $4,000). I failed my state emissions inspection and am in the process of applying for a waiver. Given how common this is, I'm surprised this isn't already a recall.

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.

10 months ago, I took my vehicle in to the local chevy dealership because the check engine light was on and I had noticed the vehicle seemed to be running rough. I had also seen a message that said the vehicle was running at reduced propulsion. The dealership told me I had a shorted EGR valve which also cause fuse 3 to blow and ordered the part. Then I waited. My vehicle stopped running on the road once. Just died. I had no battery charge remaining either. That was a safety issue for me and anyone who might hit my car because it was on the road. I sat there for a while and then tried to start it. I wasn't far from home and was able to limp home. I waited for months, contacted the Chevy/GM manufacturer and kept in contact with the dealership. Over the next 10 months was told several different things: part not being made, strike affected part manufacture, part and install price was increasing to $3500, can install Chinese part without warranty, dealership had 2 other people waiting for the part like me, part was not covered under any warranty. I was called a couple days ago to hear that there was a GM manufactured part available for my car but it would be $3500. I asked for a reduction in cost since I had waited so long. I was told they could reduce the price by $500. I said I had been quoted $1200 in 2023 when I took the vehicle in. I was told to share anything I had in writing for that. I found my invoice which showed the purchase cost for the parts ($717.80) which I just sent. I received a call today telling me the dealership has the part and will give it to someone else unless I agree to get it done today for $3500; however, since I did not know the part was even here for me, they will wait one more day to hear if the manufacturer will honor the original quote. For the last 10 months, I had no car to drive or could drive it on battery and hope I didn't run out of charge (~50 miles of battery charge) and get stranded on the road again.

[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.

Driving at highway speeds, check engine light came on with a warning of "reduced propulsion power" and sudden loss of speed in heavy traffic. Dealer diagnosed issue as failed EGR valve but is unable to source repair part due to frequency of failure causing years-long backorder.

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.

EGR valve fails causing vehicle to become disabled in traffic or stranded on a remote section of the highway. Also fails emissions testing. Chevrolet has NO REPLACEMENT parts available.

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 contact owns a 2017 Chevrolet Volt. The contact stated while her son was driving approximately 55 MPH, the vehicle lost motive power. The contact stated that the battery system became inoperable. The vehicle was towed to the local dealer, where it was diagnosed that the cells and battery needed to be replaced. The vehicle was not repaired. The dealer informed the contact that parts were on backorder. The manufacturer was contacted and opened a case. The failure mileage was approximately 69,000.

Mileage: 69,000

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.

The contact owns a 2017 Chevrolet Volt. The contact stated that while his daughter was driving at an undisclosed speed, the check engine warning light illuminated. The contact stated that the next morning when he attempted to start the vehicle, the vehicle made an abnormally loud sound. The contact shifted into reverse and the vehicle stalled. The vehicle was towed to the dealer. The vehicle was diagnosed with a battery malfunction. The vehicle was repaired; however, the check engine warning light remained illuminated. The contact related the failure to Manufacturer Communication Number: 10251431 (Electrical System) and TSB Number: N232422680 (Special Coverage Battery Energy Control Module Malfunction). The manufacturer was made aware of the failure and the contact was informed that the vehicle was not included. The failure mileage was approximately 142,974.

Mileage: 142,974

My service engine light came on. After that happened, my engine started to get hot. It got up to 230degF, received a reduced propulsion message and wanted to shut down when going 70mph on the interstate (depended on the construction). Quick reaction on my side before the engine shut down I had "held" the battery (which i do for long trips to ensure options in event of emergencies). Meaning i still had energy in the battery that could be used to propel the vehicle. I was able to shut down the engine by unholding the battery before losing control of the vehicle due to no propulsion. The electric propulsion took over and I could get off the freeway. Conditions were: I was driving in a rain storm on a very busy interstate around Eau Claire wisconsin right around 5-6pm with lots of road construction. If I would have lost the engine and power, I would have crashed at a high rate of speed. I would have lost steering, windshield wipers and headlights. Investigation showed that fuse F03 (walk home fuse) was blown. Further investigation showed that the EGR Valve circuitry was causing this failure. After unplugging EGR valve and replacing the fuse, engine was able to run and not overheat. Plug the EGR valve back in and the fuse blows again This is a well known issue on these vehicles and has been around since 2019-2020. Lots of data and information available on this issue on the internet. To make the issue worse. No parts are available for replacing this faulty valve at the moment. Only 6 valves available in the whole USA with those promised to other customers (i Called the dealers). Additionally there are more vehicles waiting for these valves.. Vehicle goes to the shop on [XXX] for confirmation of issue and get on a waiting list for the EGR Valve. I can't believe this is allowed to continue with GM. THis needs to be fixed!!!!

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.

We bought the car for our son when he began to drive. We liked the idea that it was gas and electric. At the time, our son was into electric vehicles. At 44, 000 miles, 7/10/20 the car was taken to the dealership. The engine light was on at this point, the message displayed "Propulsion Power is Reduced". Once the diagnostic was done it was said that the EGR valve needed replacing. Of course, this is during the of COVID. Everything was shut down. No one is working. It is now a wait game. Prior to this our Chevy Volt has been in and out of the dealership with either recall or something else. We enjoy the car because of how it operates with gas and electric. Fast forward it is 80,000 miles now, and the car is at the dealership again. It has currently been there for almost a month. After blowing fuses it has be diagnosed as the EGR valve needs replacing again. The part is not available currently. No one seems to know when it might be available. The part cannot be purchased from our local distributor. GM is the only ones who makes it is our understanding. There is no other dealership near us that has certified technicians who can work on them. We called around and asked. We want to know what the solution is. How can this be prevented? We were over an hour away from home and no dealership was open when it went out the last time. It became worse to the point that we were stopped on the road with flashers on because it was not safe to pullover. Prayer works.

EGR Valve failed and blew fuse while I was on road. I do have the part for inspection if necessary. Part failure caused reduced propulsion in traffic on interstate. Due to GM not manufacturing part, I had to order a refurbished part from China so I could get it put in and use my vehicle after 3 months of waiting for OEM part to come in. Component has not been inspected by anyone, outside of mechanic who would have replaced it. No warnings or symptoms of issue were observed before the part failed.

On 2/11/23, our 2017 Chevrolet Volt displayed a check engine light and the engine started to overheat, as determined by the driver from the dash coolant temperate display, while driving down the interstate after 1 hour of driving. The car was pulled over to the side of the road and towed home. Upon inspection of the Chevy Volt later, the F03 15 amp mini-fuse(referred to as non-walk home fuse) in the main engine fuse block had blown, which had likely caused the electronically controlled thermostat to close and the engine to quickly overheat, due to lack of coolant. The reason why the F03 15 amp mini-fuse blew is because the control board for the EGR valve catastrophically failed and overloaded the fuse of this important shared electrical circuit. The electronic thermostat is part of this shared circuit, in addition to the EGR valve and possibly other important vehicle functions. I consider this cascade of electronic and engine/cooling failures to be a safety issue for the driver, in addition to being a poor design. As GM doesn't currently have any replacement EGR valves for our 2017 Chevy Volt, which includes the EGR valve control board, we are forced to disconnect the EGR valve from the vehicle and replace the F03 15 amp mini-fuse, in order to make the car drivable. This is contributing to increased vehicle emissions and reduced vehicle efficiency. In locations with emissions inspections, this EGR valve parts shortage results in the vehicle failing inspection and being made undrivable. I think the NHTSA should force GM to recall any 2nd generation Chevrolet Volt vehicles that have this defective EGR valve/control board, due to its cascading effect on the safe operation of the Volt.

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)

On Christmas day, 12/25/2023 my EGR valve failed about 60 miles from home blowing my F3 fuse and putting the car into walk home mode. Luckily after some quick searching i was able to self diagnose the EGR valve as the problem as this appears to be a frequent problem with this model of car. Lots of posts online. I replaced the fuse and unplugged the valve and was able to get my vehicle home. Jan 6th 2024 a dealer confirmed the diagnosis and confirmed it as a warranty repair. Stated since the car was drivable (ev mode) i could bring it home until the part came in since it was back ordered. It has been 66 days since the diagnosis, 13 since my safety inspection expired taking my vehicle off the road due to the check engine light on. Working with both the dealer and GM directly, neither have been able to resolve my issue. I informed all parties that my inspection would expire on 2/29/2024 and my car would no longer be drivable.

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,

The contact owns a 2017 Chevrolet Volt. The contact stated while driving at various speeds, the vehicle lost motive power and stalled. The contact stated that the vehicle was restarted but stalled again after driving for several miles. The check engine warning light was illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the EGR belt needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 90,382.

I purchased my chevy volt on 8/17/2022. Early to mid November 2022 the check engine light appeared on the dash. It was determined the EGR valve needed to be replaced. I took the vehicle to Ferman Chevy Tampa on 11/21/2022. They replaced the EGR valve and we paid $1346.07 for the work completed. Then late December 2022 - Early January 2023 the check engine light appeared once again on the dash. It was determined that the EGR valve placed in the vehicle was a faulty part and the volt needed a new EGR valve. We waited approximately 1 month for the repair. Early November 2023 the check engine light came on once again. After inspection it was determined that once again a faulty EGR valve was placed in the vehicle. This is the 3rd time the same issue has occurred in a year. Today is Monday 2/26/2024 and volt has yet to be repaired, that is nearly 3 months! Apparently the part is not available and GM has no idea when it will be available. We were recently told possibly 2025. My husband came across some information stating that 1,600 people are currently waiting for an EGR valve for their Chevy Volt and that 2,000 have been ordered, but no one knows when they will arrive and after 3 EGR valvles going bad in one year even if the part becomes available I don't know if that will fix the problem or if it will just happen again. The car is inoperable for any long distance driving. We paid $26,431.83 for this vehicle a little over a year ago and its basically inoperable with solution from Chevy or GM. Aside from this issue I love my Chevy Volt. Its actually the 3rd one I have owned, but this is not fair to me as the consumer when they cannot reslove the issue. Thank you for you consideration in this matter.

Sudden failure of exhaust gas recirculation valve resulted in unexpected significant power loss on limited access highway and immediate loss of speed and acceleration. Driver was able to move to side of road with care and proceed in "limp home" mode. No warning lights activated prior to this event. Event could have been catastrophic if it occurred during heavy traffic conditions. Occupants could have been trapped in vehicle stuck in left or middle lane with no way to safely merge into oncoming high speed traffic. Car is available for inspection. GM dealer has provided the diagnosis of repair and suggested replacement of ERG valve and ERG valve cooler. This is a known defect and GM is unable to provide timely delivery of replacement parts. Waiting period of up to six months was predicted by GM dealer. Driver reports posted on internet forums reflect many Volt drivers reporting these same events and concerns.

Recall work was performed by dealer for EVAP pipe. Insulative repair was used because pipe had not worn through. This was advised to me from dealer that performed recall work. June 2023 took vehicle to dealer due to check engine light being on. Was advised that insulation that was applied to resolve recall had "slipped" causing EVAP to develop a hole and was needing to be replaced at this point. Opened case with GM with no resolution due to failed recall work. Did not feel I should be responsible for labor due to failure of their recall fix.

The contact owns a 2017 Chevrolet Volt. The contact stated that while driving at an undisclosed speed, the vehicle inadvertently lost motive power. The contact was able to pull to the shoulder of the roadway, where the vehicle failed to restart. The check engine warning light was illuminated. The vehicle was towed to the dealer, who diagnosed a failure with the engine valves. The vehicle was not repaired due to parts not being available. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 84,000.

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.

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.

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.

Upon starting vehicle and shifting to drive, vehicle gives message to "shift to park" and will do nothing else. Also, while battery is fully charged, vehicle will display "unable to charge" and show no mileage left on EV mode - then at times (but not always) upon starting vehicle, mileage increases to what it expected.

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.

My Chevy Volt has been having spotty pop-ups stating that "Propulsion Power is Reduced" for about a month, but I was not sure how reliable the pop-up was as there were plenty of days the pop-up would not come on when starting the car. On the day of my incident in October 2023, I once again received the "Propulsion Power is Reduced" pop-up when I started my car. While driving, I stopped at a stoplight, and my battery drained. When the battery is drained, I usually don't have anything to worry about, as the Volt is an EV hybrid, and I can use the gas until I can charge my vehicle again. But the Check Engine Light came on when the battery drained this time. When the light became green, I started to drive like normal, but I suddenly got a pop-up on the screen regarding the engine no longer working, and the car rapidly began to cruise while I was in the middle of the road. I was lucky enough to have space to pull over to the side, have a tow truck to get me, and not be in the middle of a busy street or highway. I scheduled an appointment with my local Chevy dealer for an inspection and figured something could be done to fix my vehicle. I was told my car was under warranty and what parts were needed to repair it. This was in October 2023, and I have been waiting for nearly 3 months for the EGR Valve required to repair my car after being told countless times that it is in backorder. I don't understand how a part can be in backorder for so long for a vehicle that is not being produced anymore. I was told I could drive my car in electric mode, but I do not want to risk the safety of others by having my battery suddenly become drained, as the EV Range the dashboard shows is never correct and rapidly drains.

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.

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 failure can cause the car to become immediately inoperable w/ no propulsion due to fuse pop. EGR required to pass emissions regulations but none are available.

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.

Around the tenth of November my car, a 2017 Premier Volt bought used, began to display an information message that the propulsion power is reduces. It displayed 0 mi EV range, even though I knew I had some left. When I started to drive the engine seemed louder than usual and the check engine light was on. I pulled into a parking lot, and checked under the hood just to make sure nothing was obviously smoking or sparking. I turned the car on and off, and drove around the parking lot a few times until it resumed normal functionality, however the check engine light remained. This was after dark, when I got off work, and I drive home on Highway 49. I did not want to drive it home on the highway in the dark until the issue seemed resolved. Since the manual claimed that if I see both reduced propulsion and check engine light I should immediately take the car to my dealer, I made an appointment with them for the sixteenth of November. For the next couple days I continued to have the same issues, propulsion reduced, incorrectly displaying 0 EV miles, and the check engine light coming on. Starting and stopping the car, or driving around the parking lot a couple times seemed to temporarily solve the issues. At the dealer, I was told there is no ETA on the part, and that it is back ordered or wait listed. The issue is with the BCEM or battery energy control module. They provided me with a rental car for the time being. A few weeks have passed, so I called them today, the 11th of December, but there is still no eta. They are still waiting for the BCEM, which is back ordered.

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.

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.

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.

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

Egr valve failed causing walk home fuse to blow causing vehicle to shut down while driving. Check engine light did come on. The problem was reproducible as car would not start, egr valve needed replacement. I would like to add that the video on youtube on cleaning the egr valve for this car has 27000 views, with is more than 1/3 of the number of Chevy Volts of this generation that have been sold. This is a serious and consistent issue.

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.

BECM issues causing vehicle to lose power, not go in to park, will not remote start, battery failure, and not turning on or not turning off when prompted.

Was driving on the highway at approximately 70mph for a couple of hours, when I suddenly received a check engine light and "Reduced Propulsion Power" message. Engine temperatures were much higher than normal (220F-240F). Was able to get the car to a Chevrolet dealership eventually where they diagnosed the Exhaust Gas Recirculation (EGR) valve as faulty. There are no parts available for months. Any time that I drive on gas power at highway speeds, engine temperatures are high and cruise control has disengaged. This is a safety issue as I am not always able to maintain speed during extended highway driving when using the gas engine.

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.

Chevy Volt's Exhaust Gas Recirculation (EGR) system valve and cooler The EGR system on these cars are faulty. I have had to take this car in multiple times related to the EGR. In Septemer 2023 car suddenly stopped on middle of highway putting my life in danger. At dealership Pohanka Chevy in Northern Virginia, I was told it was the EGR valve, I had the EGR cooler replaced by the same dealership in 2023 so I took the car to Koons Chevy in Northern Virginia for a second opinion. The dealership indicated that this is very common problem with Chevy Volts and they said the parts are not available for it. Apparently the last customer waited 3 months. Currently the car will not run on the gas engine but only on the electric which is about 40 to 50 miles which makes it non useable for me. In addition, the car will not part emissions test rendering it against the law for me to use even if the engine was running. I reported this to Chevy corporate (case number XXX) and now it has been multiple months and nothing has happened except Chevy sending me a email every ten days indicating they do not have a part. They will not also give me a rental (I have to pay out of pocket and they will reimburse me which is something I cannot afford). Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, I took it to two chevy dealerships in Northern Virginia and one in Georgetown Delaware. They cannot correct the issue since there are no EGR valves. The car will not pass emissions test. The Chevy dealer I am using is Koons Chevy at Tysons Corner, Phone 703-448-7221 (POC was Johnathon) Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Check engine light I purchased this car brand new of the lot ($37K) and now saddled with something that is of no use INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATI

Intermittent starting Had car towed to auto shop Auto shop stated that the B.E.C.M Board is going out Battery Energy Control Module G.M Has a class action lawsuit over this matter

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.

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

When the EV charge runs out and car turns on gas engine. Gas engine will run for a few minutes and then turn off with an error message on dashboard. Car will only drive safely for as long as you have EV power, which is a problem since the gas engine is used when the EV power runs out. Mine failed on an interstate, but I made it to a safe place to stop only because I had a tiny bit of EV charge left due to my practice of using hold mode to save some battery power on long interstate drives. Service reported back that it is a faulty EGR valve and I am waiting to find out if they can even get the part in stock. GM is not adequately stocking these EGR valves. The failure rate from known manufacturing/design defects is higher than the rate that they restock them. These cars are not street legal when the EGR valve fails due to their inability to pass emissions testing since the EGR failure causes the service engine soon light to be on. An owner cannot renew the registration to legally drive the vehicle once the EGR valve fails, the whole car is undriveable without the part being available.

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.

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.

Dear Madam or Sir, regarding the recall of Chevrolet Volt 2017. The vehicle made in USA, VIN No [XXX] has been bought an officially from IAAI auction (after an accident, but repairable) and delivered to Lithuania (Europe), repaired successful. The information regarding the recall has been found in an official GMC site (the details please see in att.) Starting from March 2022 I have been tried to contact to GMC US (Chevrolet authorized dealership is not exist in Lithuania, just for Cadillac), but any help did not received yet. At this moment the vehicle is not safety to drive, because already several times it's has been stopped in a road - the defected Energy control module, which has been mentioned in recall. So, be so kind and help to pass this problem. Waiting the comments Thanks for the kind replay. Sincerely Doctor[XXX] P.S. the conversation please make by email INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

Driving and check engine appeared. Vehicle hybrid power train acted erratically, switching into and out of limp mode. Potential loss of control without any previous warning signs. Diagnosed with a failure of Battery Energy Control Module 24296900. Multiple complaints of the same issue from other owners. 5 other same model cars at dealership waiting for the same part. Estimated arrival is 8-12 weeks. This has been a well documented problem since 2018, and Chevrolet has released a TSB acknowledging the issue, and potentially loss of control and stranding.

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

BECM issue diagnosed by dealer, told it would be fine to drive car while awaiting parts. Error message simply stated unable to charge. BECM failed while driving down road. Car stopped running, no power to anything, and had only enough inertia to make it into a parking lot sideways. Car was unable to restart for some time. Luckily the road was 2 lane and no traffic. Had this been the expressway the no power would have been dangerous. GM does not have replacement parts and it appears the part is known as defective. Sudden catastrophic loss of all power while driving is dangerous. Car has been parked out of caution to not repeat the loss of power during driving. Major safety concern. 3 issues: 1.sudden catastrophic power loss and 2. Dealer repair department stating it is ok to drive based on GM technical bulletins and repair details. 3. Lack of replacement parts with documented failure of these specifically for 2017 model year.

gas engine emission recirculation valve failed. thermostat failed. fuse blown. Displayed message "propulsion power reduced" and "gas engine unavailable" while driving. It put the driver at risk due to being stranded in the middle of nowhere. Towed to Dealer. They replaced EGR valve, egr cooler, fuse and thermostat. Plug-in hybrid with 90 percent ev only miles. So at 52,000 there is only 5200 miles on the gas engine. Root cause of failure unknown.

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/

Bulletin 18-NA-261 BECM failure. This is a known problem on Chevy Volts dating to 2018. This should have been a recall. Instead Chevy waited for individual customers cars to fail. Currently people have been waiting for 3 months for the part. The car is undrivable until part is replaced. GM should have ordered a recall in 2018/2019 or should have had a stockpile of these parts. My car is currently at the dealership, it has been there for 10 days and they have no idea when the part will be available.

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.

My car had the Shift to Park and Battery Control Module go out while on a family trip with the family in the car, on the highway. The car was in the left lane of 2 lanes on the highway with no propulsion or way to move it except to push push the car off the side of the highway. Thankfully some people stopped to help. My car had stopped with no way of moving on a 55 mph 2 lane highway. We were at risk of cars not seeing my hazards and hitting us from behind. We had to push the car across the right lane to get it off the road. We had two cars stop to help direct traffic away from us while we pushed it to safety. But when we were on the side of the road, we were stranded in 100 degree heat along side a busy highway and the car was not able to use the HVAC because of the issue. This is a known issue and has been for years. A google search of VOLT Shift to Park Battery Control Module will result in THOUSANDS of complaints. It has become general knowledge that if you own this model, you WILL have this issue. They ALL will, it's just a matter of WHEN. It can happen at 30,000 miles or in my case, 111,000 miles. Chevrolet knows this as well as the dealerships. I have read many other stories of people being left stranded because of this. Chevy covers it under warranty. But my car was 11,000 mile past warranty. So I had to pay full price. Every dealership I called to see if they had the part to fix my car said that they didn't have the part AND they had 1 or more of my type of car in their dealership currently with this issue at any given time FOR YEARS. Thankfully since my car wasn't in a wreck, there was no police or insurance paperwork filed. Once the shift to park issue happened while I was driving and we were stranded, the check engine light came on. It was not on when I started the trip up until the car died. Then the check engine light came on.

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!

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.

I received a 'Reduced Propulsion' message along with a check engine light and that progressed to a 'Engine not Detected" message and stranded along the interstate in a dangerous situation. Had it towed to a dealership which had a technician which could work on a volt - he replaced the Engine Control Module fuse which "fixed" the car for about 15 miles and then the 'Reduced Propulsion' error with the Check Engine light appeared. Technician said something must be shorting out the fuse. Dangerous situation.

Shift to park message and will not allow car to be turned off. This problem also occurred ~2 years ago and the part was replaced by Chevrolet under warranty. This seems to be a serial defect

The check engine light came on followed by a loss in propulsion power of the engine. During freeway driving, a sudden loss of power posed a significant risk to both driver and other drivers on the road as the resulting sudden loss of acceleration forced other drivers to swerve around the vehicle to avoid hitting the car. The problem was reproduced when the engine came back on after 2 attempted repairs. I am very scared and concerned with my life/safety.

I bought the car in 2020. It had intermittent problems with the car registering “shift to park” when the car was in park. This would not allow the car to be started, leaving me stranded. The intermittent problem has become much more frequent now. Yesterday and today 16 Dec 2021, the car is not ever registering that the vehicle is in park. The transmission display shows I am in “P” (park), but the display keeps saying “shift to park” and the car won’t start.

I have owned the 2017 Volt since August of 2017. Late 2018 or early 2019 I started having an intermittent problem when I turned the car off. The screen showed an error message "Action required - Shift to park". The car was in park already. I would push the start button. Shift into gear and shift again into park. In the beginning that solved the problem. But the car did not fully shut down when the error message is displayed. If the door is opened, the signal that the engine is running beeps. I took it to the dealer service department . They kept the car for a day to diagnose the problem but did not get the error message. But as the problem was intermittent, it continued. I returned the car to the dealer and they said they made an adjustment that should resolve the problem. It didn't. The problem became constant and I could not shift into park. The car did not fully shut off and I couldn't lock it. I returned the car to the dealer and it was there for several days while they waited for a new shifter. It was on their EV charger full time so as to not drain the battery. The shifter was replaced in February 2019. I thought this was a random incident but found out it is not. In July 2021 the same problem returned. I called 2 dealers for an appointment and have to wait 3 weeks for an appointment. I looked online for solutions and to see if others had the same experience. I found many postings and comments with screenshots of the same error message and cars not turning off. It seems to be a defect affecting the Volt and other GM cars of the same age. I had an appointment at lunch 8/3/21 and after several tries to engage the parking gear, the car still would not turn off. I had to leave it running in the parking lot for 30 minutes and it would not lock. The car shut off normally when I returned to the office. This is not an issue of safety on the road, but the inability to turn off the car and lock it is a safety factor, especially for women.

The car suffers from periodic electrical issues where it does not recognize the current status of the transmission and says "Shift to Park" even though vehicle is already parked. This culminates in a complete failure of the control module/battery/wiring harness systems and eventually the entire electrical system stops connecting to the engine. Our vehicle is now in the shop and

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.

Car would not turn off. Got the message "Shift to park" on driver display, but car was in park. Had to cycle the gear shifter several times in order to get it to shut off.

We are having the "Shift to Park" problems described many times on various forums about this car. The car does not recognize that we have indeed shifted into Park (when we have) and remains on. Others have described power outage whiles driving and various serious issues once this problem starts. GM is aware of the problem.

Shift to park issue. Can not turn the car off as it does not recognize it is in Park.

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

Car would not shut off. Message appeared "Shift to park" on driver display, but car was in park. Had to cycle the gear shifter several times in order to get it to shut off.

When I park the car, it will not turn off. Gives the message "Action Required Shift to Park" But it gives that message while the car is in park. Originally, when it first started happening two years ago, it could not be reproduced. As such, while it was under warranty the problem could not be reproduced. Now it happens over 80% of the time I stop the vehicle. I mentioned the problem to the dealer but they could not replicate the issue. Eventually, if you move the transmission linkage around enough the error clears and you can turn the car off. But this puts excessive wear on the transmission linkage. And now, its out of its basic warranty. Its clear the problem has happened to many others out there, with far fewer miles than me (51,300 miles). Why isn't the manufacturer being held accountable for this issue?

At approximately mile 370 of a 390 mile trip while operating the engine in hold mode, the engine overheated, requiring me to pull over to the side of the road, wait for the engine to cool, and then proceed to the nearest Chevrolet dealership using the battery in order to be repaired. The first warning I received was a "reduced engine power" message. I scrolled through the status pages and found the coolant temperature to be 230 deg F. I continued to monitor the temperature until a few minutes later received the overheat warning and pulled over to the side of the road. The vehicle is a 2017 Chevrolet Volt with approximately 15,000 miles. The dealership found the EGR valve (part # 12691147) to be internally shorted and replaced it. From various internet reports this appears to be a common occurrence for this model year. This is a safety risk in that it is most likely a known defective part that fails prematurely totally unexpectedly.

AFTER BEING PARKED FOR OVER 24 HOURS, WHEN WE STARTED THE VEHICLE WE GOT A MESSAGE SHIFT TO PARK. THE CAR WOULD NOT GO INTO GEAR AND WAS UNDRIVEABLE. WE TRIED TO CONTACT ONSTAR FROM THE VEHICLE BUT THD CONNECTION KEPT BREAKING UP. WE GOT THROUGH ON OUR CELL AND WERE FORWARDED TO GM. THEY ORDERED ROAD SIDE ASSISTANCECE. WHILE WAITING, WE AGAIN STARTED THE VEHICLE. THERE WAS A BEW MESSAGE INITIALIZING: WAIT TO SHIFT BUT THE CAR DID NOT GO INTO GEAR. WHEN ROADSIDE ASSISTANCE ARRIVED, THEY ALSO TRIED WITHOUT SUCCESS. THE CAR WAS TOWED TO A DEALERSHIP. IN READING VARIOUS FORUMS, IT APPEARS THIS IS A COMMON PROBLEM AND A MAJOR REPAIR. I AM CURIOUS AS TO WHY THERE HAS NOT BEEN A RECALL FIR THIS ISSUE?

I AM HAVING A 'SHIFT TO PARK' ISSUE. WHEN I STOP THE CAR AND SHIFT TO PARK, I ATTEMPT TO POWER OFF THE CAR. THE VOLT WILL NOT POWER OFF AND I GET AN ALERT ON THE DASHBOARD THAT STATES "SHIFT CAR TO PARK TO TURN OFF". BUT THE CAR IS ALREADY IN PARK. I AM UNABLE TO LOCK THE CAR AND THE LIGHTS WILL STAY ON FOR A FEW MINUTES. WORSE YET, IT IS INTERMITTENT. AFTER MULTIPLE ATTEMPTS AT RE-STARTING AND STOPPING THE CAR IF USUALLY TURNS OFF.

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.

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.

MY VOLT HAD A SUDDEN LOSS OF PROPULSION AND WARNING "ACTION REQUIRED - SHIFT TO PARK" AND WAS IN SERVICE AT MY LOCAL CHEVY DEALERSHIP FOR 41 DAYS TO SOLVE THIS DANGEROUS ISSUE. WHEN THE VEHICLE WAS RETURNED TO ME IT WOULD NO LONGER CHARGE TO 53 MILES ELECTRIC. ON MY LEVEL 1 CHARGER IT HAS CHARGED TO 52 OR 53 MILES SINCE THE FIRST DAY OF OWNERSHIP ON 1/24/17. THE VEHICLE WILL CHANGE TO 36 - 40 MILES NOW WHICH IS GREATER THAN A 30% LOSS OF ELECTRIC CHARGE. I AM NOT REFERRING TO DRIVING RANGE WHICH VARIES WITH CONDITIONS. THE PROBLEM HAS BEEN SERVICED BY THE DEALERSHIP 3 TIMES FOR A TOTAL OF 53 DAYS. THE PROBLEM SEEMS TO HAVE BEEN RESOLVED ON THE LAST SERVICE VISIT WHERE THE SHIFTER ASSEMBLY AND THE TRANSMISSION CONTROL WERE REPLACED. I AM NOW IN ARBITRATION WITH GM UNDER THE CALIFORNIA LEMON LAW AND THE BBB. I AM REQUESTING A BUYBACK OF THE VEHICLE FOR IMPAIRMENT OF USE, VALUE, AND SAFETY.

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.

WHEN DRIVING ON THE HIGHWAY, I ACCELERATED TO PASS A VEHICLE, BUT THE ENGINE SLOWED DOWN SIGNIFICANTLY INSTEAD. A WARNING ABOUT REDUCED POWER SHOWED ON THE DASH. WE BARELY MADE IT TO AN EXIT AND A GAS STATION, AND THE ENGINE WOULD NOT RESTART, WITH ANOTHER WARNING OF "SERVICE HIGH VOLTAGE CHARGING SYSTEM". WE HAD TO HAVE THE VEHICLE TOWED TO THE DEALER.. IF WE HAD BEEN IN HEAVY TRAFFIC WHEN WE WENT TO PASS THE OTHER VEHICLE, WE COULD HAVE HAD AN ACCIDENT.

Mileage: 20,800

ON MULTIPLE OCCASIONS (INCLUDING AFTER ALLEGED REPAIR), THE VEHICLE REQUESTED TO BE PLACED IN PARK WHILE MOVING. ON TWO OCCASIONS WHEN PLACED IN PARK THE VEHICLE SHIFT LOCK ENGAGED AND COULD NOT BE SHIFTED OUT OF PARK. ON ONE OCCASION THE VEHICLE SURGED WHILE DRIVING PRIOR TO REQUESTING TO BE PLACED IN PARK. ON ALL OCCURRENCES, THE VEHICLE WOULD NOT SHUT DOWN AND ENTERED A CONTINUOUS REBOOT CYCLE WHEN THE START/STOP BUTTON WAS PRESSED, INCLUDING WHEN TOWED.

Mileage: 21,000

DRIVING UP THE FREEWAY AT A NORMAL SPEED, MY VOLT BEGAN TO ACCELERATE WITHOUT WARNING AND AFTER APPLYING THE BRAKES AGAIN BEGAN TO ACCELERATE INVOLUNTARILY. AFTER I MANAGED TO PULL TO THE SIDE OF THE ROAD BY APPLYING THE BRAKES HARD, SMOKE CAME OUT OF THE HOOD. I CALLED A TOW TRUCK AND HE HAD TO JUMP THE CAR TO START IT AGAIN.

I LEASED THIS CAR IN SEPTEMBER 2017. ON NOVEMBER 30, 2018, I GOT ONTO THE FREEWAY WHILE RUNNING ON GAS AND THE VEHICLE BEGAN SMOKING WITHIN ABOUT 5 MINUTES. I PULLED OVER AND GOT OUT AND THE VEHICLE CAUGHT FIRE AND WAS DESTROYED. THERE WERE NO PREVIOUS MECHANICAL OR ELECTRICAL ISSUES OR ANY WARNING SIGNS. I HAVE DRIVEN THE VEHICLE COUNTLESS TIMES ON GAS RATHER THAN ELECTRIC CHARGE. THE FIRE STARTED UNDER THE HOOD ON THE PASSENGER SIDE. THE ENTIRE INTERIOR, ALL WINDOWS, THE FRONT TIRES, AND THE FRONT OF THE CAR WERE COMPLETELY DESTROYED. I HAVE SEEN 2 OTHER REVIEWS ON THIS WEBSITE ABOUT SPONTANEOUS VEHICLE FIRES.

WHEN PULLING INTO MY GARAGE, THE CAR SUDDENLY ACCELERATED UNEXPECTEDLY AND COLLIDED WITH THE FRONT WALL OF THE GARAGE (PHOTO 08); WHEN I SHIFTED TO REVERSE, THE CAR CAREENED OUT OF THE GARAGE, ACROSS THE DRIVEWAY, AND COLLIDED WITH MY NEIGHBOR'S HOME (PHOTO 09), LEAVING SKID MARKS (PHOTOS 06 & 07) ON THE GARAGE FLOOR. THE CAR WAS IN NORMAL ELECTRIC MODE AT THE TIME. I PURCHASED THE CAR AS A CERTIFIED USED CAR ON MAY 3RD FROM DAVE GILL CHEVROLET IN COLUMBUS, OH. THERE WERE 12,490 MILES ON THE CAR AT PURCHASE AND A LITTLE LESS THAN 14,000 MILES AS THE TIME OF THE ACCIDENT. I AM UPLOADING NINE (9) PHOTOS.

WHILE DRIVING TO THE DEALERSHIP TO GET MY CAR SERVICED FOR NEARLY STALLING AT A STOP LIGHT MY CAR ENGINE KEPT TURNING ON AND OFF AND REVVING UP AND DOWN RANDOMLY. I WAS IN ELECTRIC MODE AND THE ENGINE SHOULD NOT HAVE BEEN COMING ON. THE CAR'S SPEED RANDOMLY FLUCTUATED AS THE ENGINE RANDOMLY REVVED UP AND DOWN. I PULLED IN TO A GROCERY STORE PARKING LOT WHERE MY CAR DIED. BEFORE DYING THE GAS RANGE INDICATOR CHANGED FROM 87 MILES TO 'LOW FUEL'. I CALLED THE DEALERSHIP TO HAVE MY CAR TOWED. AFTER 16 DAYS I GOT MY CAR BACK. THE DEALERSHIP REPLACED THE ENGINE CONTROL MODULE TWICE. THE FIRST REPLACEMENT FAILED WITHIN A 1 MILE TEST DRIVE BY THE MECHANIC.

THE CAR LITERALLY JUST STOPPED WORKING AS I WAS TURNING ON A BUSY ROAD, SO I WAS STUCK RIGHT IN THE MIDDLE OF THE ROAD WITH CARS NEARLY SMASHING INTO THE BACK OF ME. THE STEERING WHEEL LOCKED UP. THE ACCELERATOR STOPPED WORKING. I COULDN'T TURN IT OFF OR ON- IT WAS KIND ON JUST STUCK IN AN ALTERNATE MODE. THERE WAS AN ORANGE ENGINE SYMBOL THAT WAS LIT UP AND IT KEPT SAYING "SHIFT TO PARK" BUT I WOULD SHIFT AND NOTHING WOULD HAPPEN. I COULDN'T PUT IT IN NEUTRAL SO I COULD PUSH IT TO A SAFER LOCATION. NOTHING. THE TECHNICIAN ON THE PHONE DIDN'T KNOW WHAT WAS WRONG WITH IT, BUT SOMEONE WHO STOPPED TO HELP SAID HE USED TO WORK ON THESE CARS AND SAID IT HAPPENS QUITE OFTEN AND IT THERE WAS ABSOLUTELY NOTHING I COULD HAVE DONE TO FIX IT (I THOUGHT I REMEMBER HIM SAYING SOMETHING ABOUT AN ENGINE SWITCH PROBLEM, BUT I WAS SO FRAZZLED I WASN'T REALLY LISTENING TO HIM) . IF THIS HAD HAPPENED ON A HIGHWAY I COULD HAVE BEEN KILLED. I DON'T KNOW HOW THESE CARS HAVE NO BEEN RECALLED.

WE BOUGHT A NEW 2017 CHEVY VOLT AT THE END OF DECEMBER 2016 AND HAD OUR FIRST ISSUE IN EARLY FEBRUARY 2017. WHAT HAPPENED THAT FIRST TIME WAS ON (2/3/2017) WHILE DRIVING THROUGH TRAFFIC THE CAR WITHOUT WARNING TURNED OFF THE ELECTRIC WHEEL MOTORS AND WOULD NOT ALLOW US TO POWER THE CAR PROPERLY TO GET THE CAR TO THE BERM. WE WERE NEARLY WERE HIT TWICE WHILE TRYING TO STEER THE CAR OFF OF THE INTERSTATE HIGHWAY AS IT DECELERATED. THE CAR WAS COMPLETELY DISABLED AN NEEDED TOWED BACK TO THE DEALERSHIP. AFTER THE DEALERSHIP HAD THE CAR FOR A WEEK THEY RETURNED IT WITH THE EXPLANATION THAT THE CAR NEEDED TO DO SOFTWARE UPDATES AND THEY WERE TOO LARGE TO DO OVER THE CAR'S SATELLITE SYSTEM ' BUT THEY NEVER GAVE US ANY INDICATION OF HOW WE WOULD HAVE BEEN INFORMED OF THE NEED FOR SUCH AN UPDATE. WE THEN HAD ANOTHER NEAR ACCIDENT TODAY (4/6/2017) ON THE SAME HIGHWAY AND WE WERE NEARLY PUSHED UP UNDER A SEMI WHILE TRYING TO MANEUVER OFF OF THE HIGHWAY AT 75 MILES AN HOUR. AGAIN, THE CAR WITHOUT WARNING SHUT OFF THE ELECTRIC WHEEL MOTORS AND WARNED US TO 'PUT THE CAR IN PARK'. IT HAPPENED IN EXACTLY THE SAME WAY AS IN FEBRUARY BUT NO WARNINGS HAD BEEN ISSUED FOR OUR CAR AND WE ALMOST HAD A HORRIBLE ACCIDENT. MY CONCERN IS FOR MY FAMILY AND COLLEAGUES SAFETY AT THIS POINT AND I DON'T WANT ANYONE DRIVING IN THIS CAR. I HATE TO THINK OF WHAT WOULD HAVE HAPPENED TODAY IF MY DAUGHTER, WHO IS A BRAND NEW DRIVER, WOULD HAVE HAD TO DEAL WITH THE SAME SITUATION SANDWICHED IN BY TWO SEMI-TRUCKS AND WITH A CAR TRYING TO PASS ON THE SHOULDER AROUND HER ' IT COULD HAVE BEEN FAR WORSE. I AM IN SEVERAL CHEVY VOLT GROUPS ON FACEBOOK AND PEOPLE WHO LOVED THE GENERATION 1 OF THESE CARS ARE HAVING MAJOR ISSUES FROM BATTERY PACKS DYING, TO DRIVE TRAIN ISSUES, TO SPEED CONTROL PROBLEMS AND MORE WHERE PEOPLE ARE HAVING MAJOR SYSTEM PIECES REPLACED 2-3 TIMES IN THE FIRST FEW MONTHS THEY OWN THE CARS.

2017 CHEVROLET VOLT EXTREME ENGINE HAZARD: ON 22-MAR-2016 I PURCHASED A 2017 CHEVROLET VOLT PREMIER, ALL SAFETY OPTIONS. DRIVING ON FREEWAY AT 65 MPH, STRAIGHT DRIVING, RELATIVELY LIGHT TRAFFIC, THE ENGINE LIGHT CAME ON YELLOW AND STEADY (EMISSIONS SYSTEM SERVICE WARNING) BUT THE CAR UNCONTROLLABLY DECELERATED. THE FREEWAY HAD NO SHOULDER DUE TO CONSTRUCTION. THE CAR SMELLED OF BURNING ELECTRICAL INSULATION CONFIRMED BY THE TOW TRUCK DRIVER. THE CAR, WITH LESS THAN 150 TOTAL MILES, IN CLEAR WEATHER, AT TWILIGHT, 76 DEGREES, CALIFORNIA AT SEA LEVEL, STRAIGHTAWAY, HAD A SUDDEN AND NEAR TOTAL LOSS OF ALL PROPULSION. THIS CAUSED A LACK OF CONTROL (OBVIOUSLY) IN THE FORWARD DIRECTION, CAUSING AN EXTREME HAZARD ON THE FREEWAY. I AM AN EXPERIENCED DRIVER: MAKE NO MISTAKE, THIS WAS A SERIOUS MANUFACTURE'S ERROR. I CHECKED, NO PARKING BRAKE, THE CAR WAS IN DRIVE GEAR, I HAD BOTH ELECTRIC RANGE AND OVER 7/8 TANK OF GAS SHOWING A GAS RANGE OF 360 MILES - AND I HAD JUST DRIVEN 60 MILES. THERE WAS NO BRAKE SMELL, AS I DID NOT NEED TO APPLY THE BRAKE BECAUSE THE ENGINE GAVE NO PROPULSION. MY HAND WAS OFF THE REGEN SWITCH. THE CAR HAD A MAJOR MALFUNCTION CAUSING AN EXTREME HAZARD, AND BASED ON THE SMELL, POSSIBLE FIRE HAZARD.
