2017 Chevrolet Volt

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 involved in a wreck when I experienced these issues. I was not aware I could file a report about this until I read there was an open investigation on the same issue I had.

The contact owns a 2017 Chevrolet Volt. The contact stated that the vehicle failed to start up after multiple attempts. Due to the failure, the vehicle was towed to a local dealer where the mechanic informed the contact that the 12-volt battery needed to be replaced. After the battery was replaced, the contact stated while driving 65 MPH, the Propulsion Power reduced message was displayed. The vehicle was towed to AutoNation Chevrolet West Colonial (3707 W Colonial Dr, Orlando, FL 32808) where the contact was informed that the battery had failed for a second time within two weeks and needed to be replaced. After the second 12-volt battery replacement, the vehicle started making an abnormal cranking sound while the vehicle independently surged and then lost power. The contact stated that an unknown power failure message was displayed on the instrument panel. The contact drove the vehicle to another dealer, AutoNation Chevrolet Airport (5600 Lee Vista Blvd, Orlando, FL 32812) but the vehicle was later towed back to the original local dealer. The contact was then informed that the vehicle had a defective EGR (Exhaust Gas Recirculation) valve. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 60,000.

The contact owns a 2017 Chevrolet Volt. The contact stated while driving at various speeds, the message "Propulsion System Failure" was displayed. The contact stated that the vehicle shuddered and drove rough. The contact stated that the check engine warning light was illuminated, and the “Propulsion System Failure” message was displayed before the vehicle lost motive power and stalled. The vehicle was towed to the local mechanic. The cause of the failure was not yet determined. The local dealer and manufacturer were not yet notified of the failure. The failure mileage was 120,000.

Started acceleration on the freeway, car couldn't turn on engine, message came on dash "reduced propulsion mode" and check engine light came on, could only drive on battery, car was very sluggish, luckily had battery to exit after a few miles to get off the freeway. Had to restart car. If I had depleted the battery as I usually do that day, I would have had a dead car on the freeway with ton of traffic buzzing me and my family.

The car will occasionally lose power when driving on battery. In my experience this most often occurs after turning, but can occur seemingly randomly at other times. It's a frightening experience because you just don't know when it will occur, what you'll be doing, and how it will impact other drivers. I spent $8k trying to fix the issue and took it to two dealership issues who said the transmission needs to be replaced. We got the transmission replaced, but the issue persists. The issue happens daily. I don't know what component failed, but yes, it is available for inspection. Safety is put at risk because the car randomly loses power while driving and switches to gas mode. Yes, the problem has been seen by a local dealer. No, the vehicle or component has not been inspected by the manufacturer, police, or insurance rep. No, there are no indicators of the failure before or after the loss of power.

I was making a left turn at a light and the vehicle suddenly popped up “shift to park” warning on the dash and simultaneously lost power. The vehicle would only roll under what momentum was generated prior to the warning. Luckily I was able to get through the turn and coast safely off to the side of the road. Chevy volt is currently at the dealership being assessed. They are telling me I will need a new 12v battery and new gear shifter for $1100.00. These were replaced, but the dealership called and told me I will now need a new ECM, or something like that, for an additional $2400.00. Car is currently at Ricart Chevrolet in Dublin,OH waiting on my decision. And I’m being told the part needed is on backorder and may be a month to arrive. After researching this, it seems Chevy knows about this issue and seems very irresponsible to knowingly put volt owners in harms way. Needless to say I’m not happy and feel something should be done by Chevy to rectify the situation.

On the morning of April 27, 2022, our 2017 Chevy Volt, with what I believe to be a fully charged high voltage battery (was plugged in to charge the entire previous night) and at least a quarter tank of gas, would not start either the electrical or gasoline drive train. The 12 volt battery showed low voltage, so I purchased and replaced the 12 volt battery. The Volt continued to not start in either gas or electric propulsion mode. Checked the OBD 11 codes, and they matched up with what was reported on line to be Battery Energy Control Module (BECM) failure. On May 3, 2022, the Volt was put on a flatbed and taken to Holz Motors in Milwaukee. They verified the BECM failure, ordered new BECM, and was told none were available. Put on waiting list for BECM, and the Volt was repaired 8 weeks later on June 28, 2022. Cost of repair was $2439.63. Volt had 110,875 miles on it and was out of warranty. Not happy to bear the full cost of replacement of the BECM, but felt fortunate that it failed while parked in my garage. There were NO symptoms leading up to failure, and the car was totally unable to move. Overnight voltage drop of the 12 volt battery (the one I replaced also went dead) meant that operation of door locks, etc would also soon have occurred. Outcome would have been much worse if this failure had occurred while driving.

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
