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.
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 -€œP-€ (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 had not had a shoulder to pull on to she would have been stuck in the middle of the highway. the car had absolutely zero issues before this, but since the incident has had a check engine light illuminated and is unable to charge unless the codes are reset. it is drivable again after getting some codes cleared but as it poses a serious hazard we are trying to find a temporary car till we can get this fixed. our car has about 100900 miles on it, but these failures happen as soon as 25k-50k on a lot of vehicles. it has not been inspected by anyone yet as it happened yesterday.
2016-2018 Volts are have a hung issues with the Battery Engine Control Module (BECM). When it fails, the car stops driving and will shift itself to park. Mine lucky failed when I was stopped but the car is unable to move when it fails. It will not drive on the motor or the battery.
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 -€œ 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.
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 -€œshift 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 -€œP-€ (park), but the display keeps saying -€œshift to park-€ and the car won-€™t start.
