2017 CHEVROLET VOLT Complaints

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

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."

When attempting to turn off ignition, “shift to park” message appears even though the gear shift is already in park. Unable to power vehicle off. Already had dealer replace gear shift wiring harness when this issue occurred the first time.

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

BECM shut car down and has gone into low propulsion mode causing danger in traffic.

The contact owns a 2017 Chevrolet Volt. The contact stated that while the vehicle was parked, the vehicle failed to start up. The contact stated that there was a message stating that the vehicle was not able to be charged. The contact stated that an independent mechanic arrived at the scene and replaced the battery. The vehicle was then restarted and driven to the post office. After reentering and starting the vehicle, the vehicle started rolling backward. The vehicle was turned off and restarted several times and s operated as needed. The contact was able to drive to the residence safely. The vehicle was not taken to a dealer or independent mechanic to be diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 105,000.

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

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

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.
