2017 CHEVROLET VOLT Power Train Problems

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

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

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

While driving the car in electric mode, a chime came on and flashed 'propulsion power is reduced', then it went into engine mode and the car decelerated quickly from posted 70mph speed to less than 40mph even though I pushed the accelerator pedal and reved the engine high. While in this low power driving mode, a warning came on saying the collision detection system was disabled. The concern is the person behind me had no warning since my brake lights did not come on. He sped around me with a bit of road rage. The problem temporarily goes away when you turn the ignition off and back on. I took it to the dealer and the said it needed a new EGR Cooler 4 hours labor $1500. Chevy Dealer pulled two codes P0401 Exhaust Gas Recirculation "A" Flow Insufficient Detected P1E00 Hybrid/EV Powertrain Control Module 2 I paid them the...

Vehicle suddenly would not function. All systems became inoperable. When serviced it was determined to be a sudden failure of the BECM module which required total replacement. Part was on national back order leaving vehicle unusable for weeks.

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...

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...

Vehicle periodically throws P0964 and P0AC4 related to TSB PIC6330. Recently, this has led to poor running of internal combustion engine and low/undrivable power, almost leaving me stranded. Took multiple restarts before I could drive the vehicle. The TSB indicates to replace part# 24285319 (internal transmission solenoid control harness) however GM indicates they have discontinued manufacture of this part. How am I supposed to get my 6 year old car fixed if GM doesn't supply the part?

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

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

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

On 3/11/2023, I was heading home when my vehicle lost power in the middle of the freeway. Luckily, I was able to safely pull over to the side of the freeway. Since this is a plug-in hybrid, there are two gauges showing how much electric and gas is in the car. When I checked, both showed were empty; however, although I knew that I did not have much electricity in the battery, I had nearly a full tank of gas. The vehicle should have had automatically switched over to the gas but did not. After a few minutes of leaving the car off, I was able to restart the vehicle in gas mode and drive home safely. I brought in the vehicle to my local Chevy dealership to have it diagnosed. It was determine that the computer had registerd multiple faults p0030, 31, 54, 135, 403, 405, 443, 458 and...

This vehicle has a very dangerous malfunction. There was no power when I tried to move out of the way of an out-of-control semi truck while driving on the highway by pressing the pedal. I made every effort to maneuver because I was terrified. But because of the power outage, I could have died. This is really worrying, and I hope you can address the issue raised by Chevy so that someone else might be spared and so that future generations of electric cars are constructed to a standard that includes safety. Thank you.

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

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.

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.

Becm module is failing currently we have an engine check light that illuminates every other drive. Started November 26th. We experienced reduced propulsion message . We have experience the car not going into gear to drive or go reverse. It seems these issues occur at random. Check light codes are u2619-u2624. A dealership will be taking a look at the car on Monday

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.

The vehicle stopped operating on the highway suddenly and without warning and would not restart. I had it towed to the Chevrolet dealer. They determined power train parts were required which were backordered. They are unclear on which parts. The car has been at the dealer for 2 months waiting for parts. They have no estimate on when they will have the parts. I am concerned about the reliability issue and also that they don't have the parts to fix it for months on end.

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

-- My 2017 Chevrolet Volt experienced a failure of the Battery Energy Control Module (BECM) in the powertrain system. This failure prevented my vehicle from being driven. The BECM and related battery pack components were replaced under warranty by a Chevrolet dealership. Those parts, to my knowledge, are not available for inspection. -- From a safety perspective, my vehicle was luckily parked when the failure occurred. Many Volt owners have reported -- via online Volt forums and on Reddit at r/volt -- that the failure has occurred while the vehicle is in motion, resulting in a safety issue when the vehicle loses power and stops in the middle of a street or highway. -- A Chevrolet dealership confirmed my vehicle's BECM failure through diagnosis and code reading (see attached documentation). In my case, the BECM initially failed and I lost the ability to drive my vehicle when it was stopped...

BECM failure resulted in a situation where the vehicle drove with erratic surging power delivery throwing engine codes P1E00, U2603,U2604, U2605,U2606 Regen braking in this vehicle has a dedicated control on the steering wheel which applies only regen braking no friction brakes. When battery state of charge is high this can result in a situation where the regen braking button abruptly (i.e. during one extended activation of the button) delivers less brake force than the user is demanding.

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

The shifter of the car will NOT go into park! It takes forever. Have to shut it off, start it back up, and keep trying to get it to work. It's insane! This has to be recalled. Literally thousands of people are having this exact same problem. It's all over the internet. And I wouldn't mind if it were a simple $50 repair, but this is a $500 to $600 thing to fix and it's just not right. The gear shift cable is not long enough. Chevy knows this because they've manufactured a cable extension that needs to be installed. What does that tell you? Manufacturers defect! Please recall these vehicles for this problem and get them to repair their factory mistake. Thank you. Sincerely & Respectfully, [XXX] .

My Chevrolet Volt at 66,XXX miles had a battery energy control module (BECM). We bought the vehicle used three months ago from a dealer, but are just now seeing that the BECM is a very common complaint for Chevrolet Volts. This issue leaves the driver stranded and the vehicle bricked without the unit being able to be moved as it cannot be moved into neutral in order to be moved to safety.

The contact owns a 2017 Chevrolet Volt. The contact stated that while parked, the transmission was shifted into reverse (R); however, the vehicle failed to reverse. Additionally, the contact stated that while the transmission was shifted into drive (D) the vehicle failed to move. The check engine warning light was illuminated. The vehicle was taken to a dealer, who informed the contact that the body control module (BCM) needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 115,000.

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

When attempting to turn off the vehicle, an error message "action required - shift to park" appears even though the shifter is in the park position.

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

I pull into a parking space. Place the gear in Park and then attempt to turn the car off by pressing the Power button. I then receive a warning message informing me: Action Required Shift Car to Park The car gear is already in Park and the driver display console also shows the car is in “P” (Park). The car will not lock. I have to turn the car on and off and switch the gear back and forth placing back into P (Park) several times until the car realizes it’s in Park and allows me to turn it off. This started happening when the car hit about 36,000. The car has approximately 40,000 miles now.

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.

Our car would not start. Took to dealer for repair. They changed 12 volt baterie and a fuse. Next couple days later same problem. No start or baterie. Took back to the dealer they diagnosed a bad becm battery electric control module. They have had it for 2 weeks with no estimate on when the part will be available. I understand it is common failure on volt cars.

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

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.

I will get a "shift to park" message on the dash when parking the car and trying to turn it off. When it happens, the car will not turn off and claims it is not in park. The shifter is physically in the park position, but the car does not recognize it. I have to shift it in and out of park multiple times to get it to recognize that it is in park. On a few occasions, I have had to leave it on and lock the doors because it just would not recognize that the car was in park.

The vehicle stopped on its own without obstacles. The vehicle fails to stop under adaptive cruse control and you have to disengage to stop or it will hit the car in front. When stepping on break during adaptive cruse it lurching forward before breaking takes over causing a hazzard. When you shif to park it doesn't register and will kill battery. Adaptive cruse does not keep it centered in clearly marked lanes.

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...

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

When parking and turning off the vehicle, I get a message saying "shift to park" even though the vehicle is in park already. This keeps all the electronics and the car still partially "on."

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

Shift to park alert comes on when car is already in park. Vehicle does not recognize that it is in park. This happens almost every time I put the car in park then hit the power button to turn the car off. That’s when the message “ Shift to park” appears. GM has a service bulletin about this problem which is apparently well known. This is supposed to be covered under my Voltec warranty but dealership was going to charge me until we pointed out the service bulletin to them.

Shift to Park alert. Vehicle does not think it's in park when it is actually in park.

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.

After a little over 3 years and 16017 miles, my Volt would not recognize it had been shifted into park and would not shut off. This started occasionally doing this, and reshifting out of and back into park solved it. Finally, I could no longer get the car to recognize it was in park and could not shut off the car (still running on electricity). I drove it to the dealer, and they kept it a week. They replaced the transmission shift controller and cable. The repair total was $452.85, and my Ally extended warranty covered all but the $100 deductable. GM has a technical bulletin out on this issue: #19-NA-206.

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.

When placing my car into Park and then powering it off I get an error message telling me to shift to park to shut vehicle off even though it is in park. Problem is two fold: I cant turn the car off and the result is a battery that runs dead. Very frustrating and if the car isnt off it could accidentally be put into gear by a child.

The vehicle often will not turn off after pressing the power button, even though it is in the Park position the vehicle stays on with the console message “Shift to Park” displayed. Normally releasing and the re-engaging the foot brake and toggling the shifter lock resolves the problem, but today (Nov 22, 2021) the vehicle did not recognize that the vehicle was in Park when in a city parking lot after approximately 10 minutes of attempting to turn off the vehicle. If the vehicle does not recognize that the shifter is in park and does not turn off, the battery may drain, and if one needs to leave the vehicle, the operator cannot be sure the vehicle will remain in position. No warning lights appear for the vehicle on turning on the vehicle.

shift-to-park problem. This is a noted problem with these Volt's. The Dealer is charging around $450 to fix this problem. With more than a couple of service bulletins on this, it is a troublesome issue.

My Chevy Volt has the "Shift to Park" error. It intermittently will not turn off, which means you also cannot start it. This left me stranded at night in a county park, which closed before the tow truck could arrive. The car has 40,205 miles and the dealer says this problem is not under warranty because it is a "bumper to bumper" issue covered only under the 36,000 mile warranty. As categorized by NHTSA, this is an electrical and power train issue and is a glaring defect that is essential to the car even functioning and should not happen on a car with 40,000 miles.
