2016 CHEVROLET VOLT Electrical System Problems

The contact owns a 2016 Chevrolet Volt. The contact stated that while driving at an undisclosed speed and making a left turn, the vehicle stalled. The accelerator pedal was released, and the vehicle returned to normal operation. No warning light was illuminated. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact related the failure to NHTSA Action Number: PE23022 (Electrical System) and Special Coverage: N232432680 (Battery Energy Control Module Malfunction); however, the vehicle was not covered under the Special Coverage. The manufacturer was made aware of the failure. The failure mileage was approximately 71,000.

Driving at 75 MPH on the freeway the power completely cuts off an a message appears on my dash "Propulsion Power is Reduced" - Pressing the gas barely gives any power, Imagine being in the middle of flowing traffic doing 75 mph to close to 20 mph. Research shows me this is a KNOWN issue with GM and the problem is with the BECM control module. There is also the issue of the EGR valve which apparently is tied into the BECM. I brought to the Chevy dealer and they said the BECM NEEDS to be replace ASAP because GM knows this is a dangerous situation and GM extended the warranty on this part to 150,000 miles. My vehicle is at 152,400 miles and they will not cover this. This is a serious issue that should be a recall that forces GM and Chevy to pay for this fix as it is something they have been aware of for years and it is a major accident waiting to happen. Please make them issue a recall for the BECM fix.

The contact owns a 2016 Chevrolet Volt. The contact stated that while operating vehicle the "Propulsion Error” was displayed, and the message "Shift to Park" was displayed while driving. Additionally, the vehicle occasionally failed to immediately start. The vehicle was taken to the local dealer who diagnosed the vehicle and determined that the Battery Energy Control Module (BECM) was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the vehicle was not included in the Manufacturer’s Extended Warranty Coverage related to the failure. The failure mileage was 98,500.

•Vehicle lost power while driving on the highway at speed. The vehicle would not run with gas engine power or EV charge basically died on the road in traffic. After coming to a stop safely but not without some close calls vehicle would not start even with car having fuel of two types in it. •The battery charge would not register, and the car would not start for a little while. Display showed nothing and was only making a dinging sound. Around half hour later the vehicle started, and I drove it to my home and parked it. I have not been driving it as it seems like a safety concern with the battery system and not feeling reliable. I had tried to charge it after the initial event and it did not charge. I did only a little research on cost for battery issues and the cost made me very put off even looking at the car. The car has been sitting sense August of last year. I took the car into a GM repair shop a week ago and the shop told me that the BECM module is weak. I looked this up and found that there is a lot of people having the same issue! Also, there are 19000 cars just like mine who got a recall or Special coverage. I am told I don’t meet the requirements for the coverage even though my car has the issues. They say my VIN is not on the list, clearly this special coverage did not go far enough. There appears to be some gaps in the coverage of this issue there are tons of people having this issue a full recall should be investigated and enacted there is clearly a problem that should be addressed. The fact that most cases do not happen when the car is running seem to put this on everyone’s back burner but people are being harmed financially while GM uses loop holes to not address an issue that could cost people there time, hard earned money, lost wages, even there life if this malfunction causes accidents. There was and is clearly enough to warrant action. Letting GM get away with a half Hearted attempted at fixing this is a crime.

While driving the car displayed “reduced propulsion power” on the dash and then I lost all drive power and could not switch the plug in hybrid from electric to gas engine mode. The vehicle had to be towed to the dealer who stated that the battery electronics control module and perhaps the battery needed to be replaced. The check engine light came on slightly before the incident.

Becm failure Car suddenly stopped driving and or starting Had to have it towed home

On [XXX] the check engine light turned on in my 2016 Chevy Volt (VIN: [XXX] miles 145,xxx). I was 2 hours from home in the freezing cold snow but thankfully the vehicle allowed me to drive home without any issues (no reduced propulsion power). When I returned to the vehicle to have a diagnostic check the error light disappeared and I was unable to check for error codes. Still no issues driving under EV/gasoline. Later that day, the car stopped going completely, no shifting out of park either. EV range was reporting 0 miles despite having full charge. I plugged in the charger but it would not work (first time this happened), " Not able to Charge" message displayed. After cycling power the EV range was full range and I was able to shift into drive again. These issues were intermittent over 3 weeks, frequently standing me temporarily. After cycling power, opening and closing the door, cycling power again, the car would function normally and I could drive under battery or gasoline power. I managed to capture these error codes while the MIL light was on: U2603, U2604, U2605, U2606, U2617, U2618, U2619, U2620, U2621, U2622, U2623, U2624 [XXX] my vehicle no longer drives or shifts out of park, "Not able to charge" message displayed, CEL light on. A class action lawsuit revealed a technical service bulletin 18-NA-261 released in 2018 (see attached) accusing GM of continuing support of the known faulty module. The result of the case was Special Coverage Bulletin N232432680 which acknowledges and addresses the above mentioned issues by replacing a faulty BECM common to ALL Chevy Volt models years 2016-2018. My VIN is EXCLUDED from coverage due to being a CARB compliant vehicle despite exhibiting the same behaviors, error codes, and sharing the same faulty BECM. Of the 60,000 Volts sold in 2016-2018, only 19,000 (~33%) qualify under the special coverage terms. 100% of the vehicles that qualify for coverage are NON-CARB compliant.

BECM failure leaving car stranded in traffic with no ability to move under its own power.

Vehicle had the Battery Energy Control Module fail at about 87,000 miles. Vehicle will not start and will leave you stranded when this happens. This is a known defect and GM issued a special coverage to extend the warranty for this specific component, but for some reason only applies to a handful of VINs. Mine was not one of them, so I got stuck with a $2500 repair bill. I love the car and am not mad that they are breaking, engineering is hard. I am mad that even after a requirement from the NHTSA, Chevy is refusing to repair a known defect with their vehicles that can leave the owner stranded and is making the owners foot the several thousand-dollar repair bill. This was my first Chevy, and due to the poor way this has been handled, probably my last.

The contact owns a 2016 Chevrolet Volt. The contact stated that while the vehicle was parked, the check engine warning light illuminated. The contact used a scanner and retrieved DTC: U2603-U2606 and U2607-U2622. The dealer was made aware of the failure. The vehicle was scheduled for an upcoming diagnostic test. The vehicle was not yet diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 95,000.

CAR LOST POWER IN 02/2024, WAS TAKEN TO DEALER. ISSUE WAS NOT ADDRESSED PROPERLY. 12/2024 THE CAR WOULD NOT MOVE, TOWED TO DEALER, ESTIMATE $2000 TO REPLACE BECM, KNOW ISSUE FOR THESE VEHICLES.

My experience is proof for the investigation on “loss of motive power, including a stall, reduced power state, and/or a no-start condition due to the Battery Energy Control Module (BECM).” My safety and the safety of others were affected because the reduced engine propulsion caused me to drive at a max speed of around 50 mph, and eventually the car left my stranded a few weeks later when it would not start at all in a parking lot. The gas engine would run at an extremely high RPM to make up for the failure of battery propulsion. The dealer covered the work under warranty. The work was performed during the pandemic chip shortage in 2022 and my car was at the dealership for two months from about August to October. The check engine light would come on sporadically before the problem started, and when the failure would occur, I would get a “Propulsion reduced” message in the driver screen and the gas engine would kick on to an extremely high RPM even when the car should have been running on battery. Accelerating from a stop to a normal speed would sound like you are flooring down the accelerator to get on a highway on-ramp. I no longer have the paperwork to confirm this, but it was performed at the Fort Collins (Colorado) Dellenbach Chevrolet dealer, it may be possible for me to get the paperwork, but I no longer live in Colorado. The process went all the way up to corporate Chevrolet before the warranty was honored, and I was compensated with company points.

Shift to park message & audible alarm. Display while in motion pulling into home driveway. Vehicle stalled midway while in motion. Halfway in the street & half driveway. Displaying propulsion power reduced & Engine not available service soon. After 30 minutes of starting & restarting was able to move out of the street. However vehicle will NOT move. Transmission will shift, however will not move. Shift to park keeps popping up.

The contact owns a 2016 Chevrolet Volt. The contact stated that while starting and driving at an undisclosed speed, the "Reduced Propulsion" message was displayed. Additionally, after parking the vehicle, the "Shift To Park" message was displayed, and the vehicle failed to turn off. The contact pressed the Start/Stop button and then opened and closed the front driver's side door to turn off the vehicle. The vehicle later failed to charge and start as needed. The vehicle was towed to the dealer, where it was determined that the Battery Energy Control Module (BECM) needed to be replaced; however, the part was on backorder. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was opened. The failure mileage was approximately 83,574. The VIN was unavailable.

My 2016 Chevrolet Volt loses power while driving and the "propulsion power reduced" warning message appears. This has happened multiple times in the past few weeks and it is very dangerous losing power while traveling. After taking it to a Chevy dealer for service, they advised that it was an internal failure of the BECM (battery energy control module) and that it would need replaced. After searching online it appears that this is a common issue with the Chevy Volt models from 2016 - 2019. So much so that GM extended a special warranty to cover this failure up to 15yrs and 150,000 miles. Unfortunately for reasons I still don't understand, I was informed that my vehicle is not covered under this special warranty despite it specifically being the year and model that is affected. My vehicle currently has 93k miles and was purchased in 2016. So I am just outside the original 8 year 100k mile warranty but thought I was covered under this new special coverage given that this is an issue that GM is clearly aware of. I was also shocked to find out that there apparently was never a recall for this issue. My wife and child normally take this vehicle across town at highway speeds and I'm lucky the issue only happened to me. I fear for those who brought their vehicles and are not aware of the issue and will be told that theirs isn't covered as well.

Took the car in for service to Simi Valley Chevrolet on 8/16/2023 due to the check engine light illuminated on dashboard. They determined that the EGR valve had internally shorted so they unplugged it so as not to take down the rest of the system and placed a special order for the valve. It has now been over one year and they still don't have the replacement part. The car runs rough and occasionally stalls and sputters. I'm concerned that the car could stall while driving and is unsafe.

The contact owns a 2016 Chevrolet Volt. The contact stated while driving at an undisclosed speed, the "Engine Propulsion Reduced" message was displayed, and the vehicle was driven to an Auto Parts store. The contact called the local dealer and was advised to replace the propulsion fuse in the vehicle. The contact purchased a replacement fuse and replaced the faulty fuse. The vehicle was driven to the dealer two days later to be diagnosed. The vehicle was diagnosed, and the contact was informed that the EGR valve had malfunctioned and needed to be replaced. The manufacturer was notified of the failure. The approximate failure mileage was 60,000.

The contact owns a 2016 Chevrolet Volt. The contact stated that while the daughter was driving in reverse the warning message "Reduced Propulsion" had displayed and suddenly the power steering failed and the vehicle lurched backward and crashed into a utility pole. During the incident, the driver pressed the brake pedal but the vehicle did not stop. No injuries were reported and no police report was taken. The daughter was able to drive the vehicle home in "Limp" Mode. The contact later examined the vehicle and diagnosed that the engine battery ECM had failed. The vehicle was not yet repaired. The manufacturer and local dealer were notified of the failure but no assistance was offered. The contact was informed that the VIN was not included in the manufacturer's extended coverage for the failure. The failure mileage was 89,800.

Mileage: 89,800

Driving to work one morning, I noticed an engine light with a "Propulsion Power Reduced" on my 2016 Chevy Volt. Upon closer arrival to work, the car was behaving quite erratically with constant "Propulsion Power Reduced" errors on the dash. The A/C stopped blowing cold and immediately fogged up the front window, making me unable to see the road. After arriving at work, I could smell what could be described as a burning electrical smell coming from the vehicle, although no fires were seen. Upon checking diagnostic codes, the car had a list of codes pointing to the failure of the Battery Energy Control Module (BECM.) I researched the issue and discovered "N232432680 - Special Coverage Battery Energy Control Module Malfunction" listed by GM and the NHTSA. My Chevy Volt is within the model years (2016-18) and mileage (<150,000) for the special coverage warranty from March 2024. Upon checking with the local GM dealer, they said that my VIN is not included in the special coverage and I must pay out of pocket, even though I have the exact problem described in the warranty and my Volt satisfies other conditions (model year and mileage). I am scheduling a service appointment this week with the local dealer to formally diagnose and repair the issue.

The car has experienced a ‘BECM’ failure, which is very common on the Chevy volt. When it fails the car becomes undrivable and will slow down into reduced propulsion mode. It will not start and required us to have it towed to the dealer. The 2016-2019 Chevy volt BECM issue has been investigated by the nhtsa and gm. It is a common enough issue that gm has voluntarily issued ‘special coverage N232432680’. This covers the becm failure on 2016-2019 volts for free for up to 150k miles 10 years. We have a 2016 volt with 144k miles so we assumed it would be covered. The dealer said it wasn’t covered based on my vin but they didn’t know why our vin was left out of the coverage. Obviously if they thought our car didn’t have a suspect becm, they were wrong because it failed during the special coverage time. The repair is $2600 and gm will not assist us with this repair. I have attached a copy of gm special coverage and the bill. This seems to be a clerical error that our vin and maybe others were missed despite the fact our car falls right in the special coverage criteria. I believe this should be a full recall or 2016-2019 volts, especially if the becm has failed.

The EGR valve in the 2016 Chevy volt will fail blowing fuse 3 which will also take out the engine oil pressure control solenoid, the evap emission purge solenoid valve, the engine coolant thermostat heater, and the oxygen sensor 1 as they all share the same fuse. The car will tell you that the engine is unavailable and, if you are out of hybrid battery power, will leave you unable to move the vehicle. In my particular situation it left me stranded blocking one lane on a two lane s-bend road on a 5-9% grade mountainside with no cellphone reception. Thankfully the car stopped far enough away from the previous bend that people had time to see me and I didn't get rear-ended. If I had stopped 20 feet sooner that likely would not have been the case. The replacement part for the EGR valve is impossible to find as it is back ordered everywhere and places that will let you back order it will try to charge $1927 just for the part (no installation service included). If you live in a state without emission checks then you can unplug the EGR valve and replace the fuse but that means your producing more pollutants. Until GM gets their act together and offers affordable replacement parts I don't see another alternative.

Fuse #3 shorts out every time the engine changes from electric power to gas. We have been told this can be dangerous because this fuse controls several important systems in the car.

The BECM has failed and causes a reduction in engine power. There is a Special Coverage N232432680 for this issue. Dealership Service Center is saying my car doesn’t qualify based on the VIN, even though it matches the year, make, and model on the Special Coverage. GM is failing to cover the issue despite it matching everything on the Special Coverage.

I was driving in clear weather (with my ICE engine as propulsion) when an Engine Warning Fault light appeared on my dash and the vehicle slowed to 5mph with no response from the throttle pedal. I pulled into a parking lot, had the vehicle towed to an independent service shop, and had them check the codes. There were a dozen faults stored, but they found the 'Non Walk Home' fuse had blown, and faults pointed to the EGR Valve as having faulty electronics. They could not find an EGR valve for sale so they unplugged the EGR Valve and replaced the fuse, which allowed the engine to drive normally again, but with the Check Engine Light on at all times. I called my local Chevy dealer and they told me the EGR I needed was Part Number 12691147 for $243, but they were backordered and there were dozens of people in front of me for their dealer alone. Now, 11 months later, I'm still waiting on the part, I have found hundreds of other Volt owners online with the same issue, and the Part Number has been changed by GM to 19436113, with a price increase of 1100% to $2642. And the part is still not available because of "high demand" on a car that was discontinued five years ago.

Started vehicle with > 50mi on the EV-range. Pulled out onto road, stopped at red light. Now showed 0mi and refused to move when pressing the gas (did not fail over to gas on series PHEV) Garbage truck coming up behind me had to swerve to avoid rear-ending me as I was frantically trying to start the car. Kept saying 'shift to park' (condition required to start the vehicle) Took several minutes and 20+ tries before I got it to start (GAS engine) and was able to proceed. Car keeps randomly dropping to 0mi EV range. Has refused ot start on occasion. All symptoms align with the N232432680 bulletin but GM saying my car isn't covered???

I bought the car new in 2015 and after about only 40,000 miles I began getting a Propulsion Reduced error and the car would have very slow acceleration. I took it to the dealer and they replaced the accelerator for $500. It drove fine for a month, but then the acceleration was reduced again. I took it back to the dealer and they were stumped. They wanted to charge me $1300 just to replace some wires, but they weren't confident that would fix the problem. I declined. As it stands now I can toggle the F08 fuse and that temporarily fixes it for about an hour or so, but the error always comes back and the car has a hard time accelerating. Not safe. I called GM and they suggest I take it to another Chevrolet dealer, so I'm going to do that. I'm also going to reference NHSTA Special Coverage N232432680 Battery Energy Control Module Malfunction to see if they can replace the BECM. This is a common problem with 2016 Chevy Volts. If they can't fix it, I'll look into the California Lemon Law to see if I can get my money back on the car. I appreciate your support on this.

The car states the battery will not charge and cannot move the car. I connected it to a code reader with the following codes showing: P1E00 U2618 U2606 U2605 U2617 U2604

This vehicle has been intermittently displaying shift to park, reduced propulsion and loss of power. Chevrolet will not address its problems utilizing the March 6, 2024 service bulletin that covers this model year despite it exhibiting these dangerous warnings and reduced power and stoppage. Please help!

The contact owns a 2016 Chevrolet Volt. The contact stated while driving 40 MPH, the battery was fully charged; however, the mileage range went to 0. The contact stated that the fuel system engaged, and he drove to the dealer, where it was diagnosed that the electronic control module (ECM) had failed and needed to be replaced. The contact related the failure to GM Campaign Number: N232432680; however, the dealer informed the contact that the vehicle was not covered. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that they could not assist because the vehicle had a Salvage Title. The failure mileage was approximately 44,000.

Chevy has put out a "special coverage" (number XXX) on 2016 to 2018 volts on the BECM issue that is currently being investigated. I need to make the note that upon trying to fulfill this warranty/ special coverage on my 2016 volt, they are finding loopholes to not cover a huge handful of 2016 to 2018 volts that have the exact same BECM issue and components as the volts that are covered. Although I'm not positive, it seems to me that they are not granting special coverage to all volts that have a PZEV warranty in place as it's redundant. However, 75% of us with PZEV warranties are in non CARB states and cannot utilize the warranty. So they are leaving us within this category who have the exact same BECM issues as every other 2016 to 2018 volt out of being eligible for the new coverage, while making it look like they are fixing the entire issue. They are secretly leaving a handful of us dry and without this coverage. Not only that, they are refusing/ unable to give me accurate information as to what vehicles qualify for this warranty if not all 2016 volts which is against the Magnuson-Moss warranty act and illegal on their part. They forced me to pay $2500 for this repair after telling me I would be covered by warranty and obviously would have held my car had I not paid. After telling me it was free. Somebody needs to probe deeper into this and make sure that Chevy is honoring what they claim because it appears to me they are secretly trying to [XXX] a percentage of 16 to 18 volt owners who have the exact same issues and components as the cars that are covered. This is a safety issue as my car died and temporarily stranded me several times before this repair as you guys already know is an issue with the 16 volts that Chevy has refused to acknowledge until recently.

I got the “propulsion power is reduced” warning at ~83.5k miles on the odometer, while visiting friends 4 hours from home. Pulled over and called 3 local dealerships and all servicing departments are closed on Sunday so knew there was nothing I could do except try to limp back to my friends house safely and reevaluate. On the 20 minute drive back, the engine cut out on the freeway and the car immediately started slowing down. I coasted to the next freeway exit safely with my hazards on. The scary part was that I had no power after the ”engine unavailable” warning popped up since the battery was completely drained already. I was able to get it towed to the closest chevy dealership and leave the keys for them. I am waiting to hear the official diagnosis from the dealership once they take a look. The cause is still unknown but this sounds like a similar series of events for BECM failure.

The contact owns a 2016 Chevrolet Volt. The contact stated that while at a stop light, the vehicle suddenly shut off and would not restart. The vehicle was towed to the local dealer who diagnosed that the high voltage battery was faulty and needed to be replaced. An engineer was sent by the manufacturer to examine the vehicle and confirmed that the high voltage battery was faulty. The contact was later informed that the manufacturer had authorized the high voltage battery replacement. The failure mileage was 91,000. The VIN was not available.

Vehicle suddenly lost power and displayed shift to park on display. Vehicle will not respond or display any status other than shift to park. Vehicle towed to dealership. Diagnosis of their mechanic is failed BECM module. Vehicle was brought to dealership 3yrs ago with infotainment center problems. Infotainment Software was updated but problem persisted. 2 years ago it was brought to dealership with complaint of intermittent inability to charge propulsion battery. Sunshine Chevrolet stated their mechanic could not diagnose issue so it was not covered under warranty. I demonstrated intermittent charging issue by plugging vehicle into dealership charger in front of showroom. I was at that time allowed to leave without paying diagnostic charge. 1½ years ago while car was still under warranty car failed to start. Called dealership. They stated it could be 12volt battery. I purchased and replaced battery at dealership. Car started but intermittent charging issue and intermittent infotainment issue continued. GM is refusing to cover BECM replacement saying Car is now out of 8yr warranty time frame.

Check engine light on. Took to dealership and they have a bulletin that states they need to replace the Battery energy control module. The car can come to a complete stop without notice. I don't feel safe driving the car. Was told my voltec warranty ran out last July. This is going to cost me over $2000! And they knew about it. It's a defect in the car. Needs to be recalled!

I picked up my vehicle from Wasler Polar Chevrolet on 7/26/2023 after they claimed to have "repaired" my vehicle. After receiving my vehicle, about 5 miles away from the dealership, my vehicle suddenly quit keeping up with traffic, and lost *all* power equipment. Brakes, steering and acceleration were all unresponsive. The vehicle almost sent me under a semi-trailer, but I quickly forced the steering wheel to the left and engaged the emergency brake, which successfully stopped the car. The vehicle bricked itself, and had to be towed back to the dealership.

While driving suddenly the battery power died (1/3 battery life left) and the ICE came on reving very high and check engine lights came on and vehicle slowed. Pulled over at first spot I could find and tired to restart the car. Car would not power down or restart the ice motor and the electric drive motors stopped working and vehicle would roll backwards once put into drive. Vehicle had to be towed back to dealership. Car would not power down or reset.

Check engine light came on reduced propulsion warning. Took to Chevrolet dealer and they diagnosed EGR value failure while on road trip. Got home Took it to my local dealership and same diagnosed no part available and emissions warranty is good and it is covered but 2 year nationwide backorder by GM. The car only shows 47000 miles without parts I will not be able to use the vehicle after it fails the emissions test for Maryland.

*BECM, Main Battery issue. It is available for inspection at the dealership *Car would not start or move *At dealer, told they need to replace the main battery and BECM *Noticed the Engine warning light and Reduced Propulsion Power message Dealer updated the BECM, said it was ok to drive, With in the same day the same problem happened, back to dealer, now they say the entire main battery needs replacing. on 2 months left on Voltec warranty. $8,000 cost

The contact owns a 2016 Chevrolet Volt. The contact stated that after starting the vehicle, the vehicle initially failed to shift into drive. After the vehicle was shifted into drive, the contact stated that while driving at an undisclosed speed, the vehicle lost significant motive power with the “Low Propulsion Power” message displayed. The contact pulled over to the shoulder of the roadway, where the vehicle stalled and failed to restart. The check engine warning light was illuminated. The vehicle was towed to the dealer, who diagnosed a failure with the battery energy control module. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 160,000.

I had just left my house about to enter the on-ramp to Interstate 95 south when my 2016 Volt abruptly and without warning stopped. I was unable to coast or pull the car to the side of the road. I was in the middle of the lane in a dangerous place to stop a car and a dangerous place to get out of the car due to the steady traffic entering the interstate. My car would not restart and I had it towed to the Portsmouth NH Chevy dealer. As it was the beginning of the GM strike I had to wait several days for the replacement battery control sensor then I had to wait for another 4 weeks or so for a replacement transmission to be installed. The day after I got my car back, about 2 weeks ago, the transmission fluid was leaking onto the garage floor. The Chevy dealer has ordered new transmission hoses but only one has come in and I was told not to drive my car until these were replaced. The sensor pad and transmission were covered under warranty, I was told the hoses to the transmission and labor to install them are not part of the transmission and not covered. The incident has been extremely inconvenient but the way my car just abruptly stopped and wouldn’t restart was very unnerving and could have been very dangerous. I do not have paperwork at the moment but can provide a dealer invoice of the covered work so far. Please contact me with any questions.

Shift to park issue where suddenly I can't start car . Doesn't register park. Have to fiddle with shifter. Then find on reduced propulsion.

Component: Dealer said its the BECM. Lots of them failing, check any Chevy Volt forum. What happened: Driving on road, battery drive turns off and it switches to gas engine, "reduced propulsion" message pops up, then gas engine quits and 'shift to park' message pops up. No electric motor, no gas engine, coasting, then stuck in road, traffic piling up behind me. After half-hour or so of blocking traffic and me trying to restart the car, electric eventually 'reset' and it worked fine again, so I drove it the several miles home, and the charging system connected fine. Next morning, charging system said it was broken, and car would not start. Towed to dealer. Safety risk: Both battery drive and gas engine turned fully off while traveling on road - no power, and steering/brakes hard to use. Luckily was in slow lane on local road near corner with traffic light, so others were 'prepared' to slow down, avoided my stopped car, and were able to get around. Prior Symptoms: Within the prior week, battery drive switched to gas engine with 'reduced propulsion' popup, but then it switched back to battery drive after stopping and restarting. Several times noticed the 'battery charge' indicator would change color and the estimated mileage remaining would bounce between 0 and 47.

my forward proximity sensors would randomly trigger. One day my ambient air temperature went haywire, checked for codes and had high voltage reading ambient air, brake booster trouble. after further investigation found that the X100(female) connector had water intrusion causing shorts across the pins showing voltage to drop across other pins further sending false or incorrect signals to the computer. the connector was thoroughly cleaned and aired out. now wrapped intensively with a lot of electrical tape in hopes to prevent water from getting in and causing voltage that range from 5v-14v from shorting across terminals and causing false activation.

vehicle suddenly stopped while driving , engine light came on and on board charging system maintenance showed on dash display , I was able to restart it and take to the dealer for diagnosis they said that the BECM needs replacement at the cost of $2500.00 and that it is common on this vehicle ,this issue is a safety problem GM has issued a TBS for this defect recognizing it as an existing defect, this would cause a tragedy if it occurs while driving a on the highway ,since the car would loose power and could cause a catastrophic accident . the cost of the repair for a known defective part is unfair to the consumer and should be the manufacturer responsibility to bear the cost for safety .

While on a road trip, we were traveling on a rural highway at roughly 55 mph. We received a warning message on the dashboard stating that "Propulsion power was reduced" and the engine began running rough, with surging noticeable based on throttle position. We also noted that engine temperature was rising above what was typical for the vehicle. The vehicle was able to maintain highway speed, and we were able to limp the vehicle to a safe location. Based on a web search, we were able to diagnose the issue (a failed EGR valve) as well as a way to limp the vehicle to a local dealership. They made a change that allowed us to limp home safely (unplug the EGR valve's electrical connector and replace the blown fuse under the hood). The vehicle was taken to a Chevy dealership when we made it home. The failure we had diagnosed was confirmed, and the component was replaced. The repair was not covered under warranty, and cost a significant sum to repair (1139.91). Additionally, this appears to be a very, very common failure for this make and model of vehicle- to the point where there is so much demand for this repair to be performed that these components (the EGR valve specifically) are difficult to obtain from Chevy. Additionally, the failure mode is such that when the EGR valve fails, it pulls excessive currents, and blows a fuse that also controls a number of important engine cooling components, leaving engine cooling significantly compromised. If we had been going faster, or if the weather was warmer, or if the load inside the vehicle was heavier, it would have been easy to overheat the gas engine and leave us stranded. I am concerned about the incidence rate of the failure, (based on online reports) the relative small number of miles on the vehicle when the failure occurred, (~57k) and the possible knock-on effect of the failure of the gas engine's ability to cool itself due to a relatively unrelated failure.

The contact owns a 2016 Chevrolet Volt. The contact stated while driving 55 MPH, the battery level indicator was fluctuating up and down and then the instrument panel went blank. The vehicle was not diagnosed. The manufacturer was contacted and stated that the vehicle needed to be diagnosed. A case was filed. The failure mileage was 160,800.

Action Required Shift to Park message comes up on the dash after starting the vehicle & shifting into gear out of Park. The message goes away when shifted back into Park, but the vehicle doesn't respond when shifted into gear. Reverse, Neutral, Drive, Low - none will engage. I had to repeat the process of starting the vehicle 28 times before it would operate as it should. Start Vehicle to View Application message comes up when in Park & trying to shut the vehicle off & will not power down until the driver door is opened. I worried that I'd be stranded if this continued to happen & took the vehicle to Brad Deery Motors in Maquoketa, IA for repair on 4/14/22. I paid $736.71 & the invoice states: 106128 shift to park, diag, intermittent open in the shift park solenoid, replaced shift park solenoid and jumper harness, tested working properly. I brought the vehicle home & had the same messages appear on 4/19/22. I have since read a forum on the Volt & understand that this has been a common issue & found a service bulletin: 19-NA-206, but wondering if there is an actual recall. I plan to contact GM regarding this issue.

I have a 2016 volt bought from NYC and I am the first owner currently residing in TX. My volt currently has mileage of 30,020 but this propulsion power will be reduce error has been shown since last 100 miles or so, my commune is usually under 5 miles a day so I rarely use gas however recently due to work I have to commune pretty far for a week and relied more on gas and this error popup during on of the commune. (It slowed my car down significantly while on highway and eventually stop with message on the console says engine offline) With the following error codes found: P0031 P0054 P0030 P0135 P0403 P0405 P0443 P0458 P0489 P0597 P0598 P06DA P06DB P0AC4 P0030 This car barely has much gas mileages as it was primarily on electric, but this failure on highway comes suddenly.

There is a “Shift to park” message on the driver information screen when attempting to shut off vehicle. I don’t know if the vehicle is still in gear and will move (forward or back) when I think it is in Park. I have not had it in for inspection/repair yet, as it is a recent occurrence that is becoming increasingly frequent. This started happening around 11/15/2021.

Vehicle shift to park warning , does not go in reverse or forward , shifter moves but it does not detect is in park mode , therefore it doesn't reset battery status or able to drive in forward or reverse.

When parking vehicle a "Shift To Park" error appears on the dash and vehicle will not turn off for some time. This is an intermittent issue that seems to be getting more frequent as time goes on. Vehicle can be stolen if issue is unnoticed.

Any time that the vehicle is turned off, a warning message displays on the HUD saying "Action Required: Shift to Park". This occurs whenever the vehicle is turned off, despite the gearshift already being in Park.

1. AN ERROR APPEARS "SHIFT TO PARK" WHEN PARKING. THE CAR DOES NOT RECOGNIZE THAT IT IS SHIFTED TO PARK THUS IT CONTINUES TO RUN EVEN WHEN POSITIONED ON PARK. A RUNNING VEHICLE THAT CANNOT BE TURNED OFF AND CAN RUN ON GAS IS A CONSIDERABLE HAZARD. THIS IS AN EXTREMELY COMMON ISSUE WITH THE 2016 VOLT.

GET "SHIFT TO PARK" ERROR WHEN TRYING TO SHUT OFF IGNITION. SHIFT LEVER IS IN PARK BUT NOT RECOGNIZED BY CARS ELECTRONICS OR SWITCHES OR? THIS PREVENTS CAR FROM BEING SHUT OFF -THIS IS MORE THAN JUST AN IRRITANT. WHEN YOU ARE STOPPED SOMEWHERE AND CAN'T TURN OFF YOUR IGNITION, YOU ARE IN A REALLY SERIOUS PREDICAMENT! GM HAS HAD THIS PROBLEM ON MANY ELECTRONIC HYBRIDS SINCE 2016 MODELS AND WILL NOT OR CANNOT FIX! ONE GOOGLE OF CHEVY VOLT "SHIFT TO PARK" WILL SHOW HUNDREDS OF COMPLAINTS (MANY TO YOUR DEPT.) AND NO HELP IN FORCING GM TO RESOVE PROBLEM !

WHEN I PUT THE CAR IN PARK AND TRY TO TURN IT OFF, I FREQUENTLY GET AN ERROR ON THE GAUGE DISPLAY THAT SAYS "ACTION REQUIRED, SHIFT TO PARK." THIS IS VERY FRUSTRATING. WHEN THIS ERROR HAPPENS, I'M UNABLE TO POWER OFF THE CAR OR LOCK THE DOORS. I TURN THE CAR BACK ON, JIGGLE THE SHIFTER OR MOVE IT INTO DRIVE AND BACK TO PARK, AND THEN TRY TURNING THE CAR OFF AGAIN. SOMETIMES I HAVE TO GO THROUGH THIS PROCESS 5 OR MORE TIMES BEFORE THE CAR WILL POWER DOWN. THIS ERROR HAPPENS ABOUT HALF THE TIME THAT I USE MY CAR, WHICH MAKES IT A DAILY PROBLEM. I BOUGHT THE CAR USED IN OCT 2019, AND THE PREVIOUS OWNER ALSO HAD THE PROBLEM BUT I DON'T KNOW WHEN IT STARTED FOR HIM.

GETTING THE "ACTION NEEDED SHIFT TO PARK" WARNING INTERMITTENTLY WHEN PARKED AND ATTEMPTING TO TURN OFF CAR TO EXIT. UNABLE TO SHUT DOWN VEHICLE WHEN OCCURS.

THE VEHICLE ISSUES A MESSAGE TO MOVE THE GEAR SHIFTER INTO PARK (SHIFT TO PARK) MESSAGE EVEN WHEN IT IS ALREADY IN PARK. THE VEHICLE WILL NOT ENGAGE NOR WILL IT ENABLE THE DRIVER TO TURN THE VEHICLE OFF WHICH RESULTS IN UNSAFE DRIVING CIRCUMSTANCES AND STRANDS THE DRIVE IN UNTENABLE SITUATIONS. THIS IS KNOWN IN SOCIAL MEDIA AS THE "SHIFT-TO-PARK" PROBLEM WITH VOLT AND OTHER GM VEHICLES WHILE GM IS HUSH-HUSH ABOUT THE ISSUE. THERE ABSOLUTELY NEEDS TO BE A RECALL ISSUED FOR ALL AFFECTED VEHICLES AS THIS IS CLEARLY A MANUFACTURER DESIGN ISSUE GIVEN ALL OF THE PROBLEMS DRIVERS ARE HAVING. IT STARTS AS AN INTERMITTENT PROBLEM AND CONTINUES TO GET WORSE OVER TIME WITH OUT ANY WARNING.

MY ELECTRIC CAR WOULD NOT TURN OFF AND I RECEIVED THE ERROR MESSAGE "ACTION REQUIRED: SHIFT TO PARK" ON THE DRIVER DISPLAY . I WOULD HAVE TO PLAY WITH THE GEAR SELECTOR MULTIPLE TIMES SOMETIMES IT WOULD TAKE 20 MINUTES JUST TO TURN THE VEHICLE OFF. VISITING OTHER FORUMS, THIS IS A COMMON ISSUE AS IT IS DANGEROUS TO BE STRANDED NOT BEING ABLE TO TURN OFF YOUR CAR.

WHEN PUTTING SHIFTER TO PARK, THE ACTION REQUIRED MESSAGES IS SHOWN AS: 'SHIFT TO PARK' ISSUE. THE CAR WILL EFFECTIVELY NOT TURN OFF. YOU'LL BE UNABLE TO LOCK THE CAR AND THE LIGHTS WILL STAY ON FOR A FEW MINUTES. WORSE YET, IT IS INTERMITTENT ALTHOUGH IT GENERALLY GETS WORSE OVER TIME.

THIS IS AN UPDATE TO MY ORIGINAL COMPLAINT #:11299056 FOR UN-COMMANDED ACCELERATION ON 1/13/2020. THE CHEVY DEALERSHIP WORKED WITH GM CORPORATE ENGINEERS AND WERE UNABLE TO DUPLICATE THE PROBLEM AFTER SEVERAL DAYS. THE RETURNED THE CAR AND BLAMED IT ON THE FLOOR MAT. THIS IS NOT LIKELY SINCE THE MAT IS A OEM HEAVY RUBBER MAT AND THE ACCELERATOR PEDAL DOES NOT REST ON THE FLOOR BOARD. SINCE THE CAR WAS RETURNED AND DRIVING FOR WEEKS, I NOTICED THE BATTERY RANGE WILL NOT CHARGE MORE THAN 49 MILES OF ELECTRICAL CHARGE WHEN IT OFTEN CHARGED UP INTO THE 50-60 MILE RANGE PRIOR TO THE INCIDENT. I'VE BEEN DRIVING THE CAR IN SLOWER HEAVY TRAFFIC LATELY AND THIS DRIVING STYLE OFTEN INCREASES ELECTRIC MILEAGE RANGE AFTER A FULL NIGHTS CHARGE. IT WILL NOT DO SO ANYMORE EVEN THOUGH THE ECONOMY MANAGEMENT SCREEN INDICATE MAXIMUM RANGE ECONOMY OF OVER 250 MPG. I'M A RETIRED GAS TURBINE MECHANIC AND I KNOW A PROBLEM WHEN I EXPERIENCE ONE. I SUSPECT THAT A BATTERY CELL MAY HAVE HAD AN UNCONTROLLED DISCHARGE AND IS NO LONGER ABLE TO ACCEPT A RECHARGE. I HAVE RELAYED THIS INFORMATION TO THE DEALER. NO RESPONSE YET.
