general problems of the 2014 Chevrolet Volt

I was slowly maneuvering my car into my garage when the vehicle suddenly and unexpectedly surged forward, despite only lightly tapping the brake and not touching the accelerator. The car had been displaying the warning, “propulsion power is reduced” and was not holding an electric charge in the days before the incident. No malfunction indicator lamp ever turned on. Per the owner’s manual, the vehicle did not need to be serviced because the malfunction indicator light never came on at the same time as the propulsion power reduced message. This led me to believe the vehicle was safe to drive. The unexpected surge caused the car to strike and cause considerable damage to the garage wall. Fortunately there was no one in the garage at the time and I, myself, was not injured. My car was deemed a total loss by the insurance company.

Vehicle stopped when changing from battery power to gasoline. Unable to drive. Not charging the lithium battery therefore, I experienced 3 similar incidents with this vehicle. The first one on 02/15/22. The vehicle was towed to bommin Chevrolet in florida city, FL. This time it was under warranty. The second time 01/02/23 while on the road similar thing happened, again was towed to tropical Chevrolet in north miami, FL; a diagnostic was performed the error code was cleared and started charging again. This time same issue when the main battery was depleted the vehicle stalled. I had to towed to my home where is still sitting. Not operational.

I bought my car and I had no idea about a known issue that this car has. Unsuspecting and trusting, I noticed my car had a reduced propulsion and it would like lose power and just slowly jerk and then really drastically reduce speed without anyway to fix it and on the freeway I got scared as I have never in my life has this happen in any car. So it happen a couple more times and I took a picture of it and took it to the dealership where I purchased it. They told me they couldn’t do l as they can’t repeat the issue. Well that only usually happens when I’m driving but now it’s more. The propulsion thing loses power and I as a driver going up a hill or anywhere now will lose speed and it’s dangerous, I feel like I may not make it home and I took it to the dealership many times and they told me there’s no issue. I took it again recently now that I’m out of warranty because it also had some high Voltage issue and a sensor coolant issue that misreads. I like the car but very unhappy about dealership and manu not fixing this issue that every Volt owner I talk to has, read about. I lose power, my car randomly heads up when it’s been cold all night and not driven now I have the same issues. I have the same issues and I use 91 gas, I have inspected my car and I had to learn about cars or more than I ever did which was like zero all because of this car. I even took it to the dealership 3-4 times (documented) to get it fixed and they just said there isn’t anything wrong nor did they say there’s a known issue and watch out for this or that. I had to look up the issue and learn about it on my own. Very dangerous date happening this is happening now almost everyday but was frequent 1. 5 years ago but last 8 months it’s like the standard. I’m afraid my car will lose power on freeway, which it does and I have to take toll to stay away from others for everyone’s safety.

Starting up the car in the morning, the display panel went dark. I turned off the vehicle and tried starting up the vehicle again with no change. The display panel is dark. I am not able to see gas information, battery information, speed, and turn signals.

While driving in gas mode, while coming to a stop the engine feels like it is rattling loudly and vibrates the steering wheel. When accelerating, the engine feels like it is rattling the car, shaking the car, and the steering wheel is shaking.

Car is a 2014 Volt with 1900 miles. I bought it new recently as a dealer display model with 100ish miles on it. Last night (10/22/15) on our trip to visit family and friends out of town, I was driving the car in hold mode (cruising at highway speed) and l. It had about 20 miles of charge left. Speed was approximately 65mph cruising. I suddenly get a dash indicator indicating that I am in reduced propulsion mode. The car's power is reduced, throttle input is decreased, and I am not able to accelerate as before. I move over the the slowest lane ASAP. The internal combustion engine was now off and I had switched to using the remaining charge. I then called onstar. They ran a diagnostic and came up with two codes (these are as detailed as my passenger could write down): 1. P0700 transmission not preforming as expected. 2. P0777 power trans? system detected malfunction with transmission control system. May affect vehicle performance including shifting behavior. Luckily we were able drive to the nearest dealer and have a family member pick us up. The dealer verified the codes, cleared them, but was unable to "reproduce" the problem. Therefore they made no change and returned the car to me. Multiple other owners have also had this problem and has not been systemically troubleshooted by chevy as the local dealer's had no idea how to service.
