A similar issue is currently listed under the 2013 Volt here but I experienced it on a 2014 Volt & it led to complete engine failure while driving, very different than just "reduced propulsion power". I was driving my Volt on its extended range mode with the gas engine (days earlier, I had taken the car to a repair shop & gotten a green light on it) & I got an error message "service power steering--drive with caution". that error message then turned to "service parking assist" & then "service stabilitrak", but it was driving fine & I intended to take it to the dealership the next day. Then before I could get home, the message changed to "propulsion power is reduced", so the car couldn't drive as fast as before. I still needed to drive home so I turned on my hazards & then that error message morphed into "engine not available, service soon". now it's still driving okay but then all of a sudden it decelerates completely and stops moving in the median on the highway. I was lucky to be alive. I was never informed of any recall on any Volt & I previously owned two other 2013 Volts.

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.

My car stalled on the freeway ramp with engine warning reported on the dashboard. The issue was identified to be due to engine propulsion and transmission failure and they would have factory technician replace/rebuild all related components as a preventative maintenance/repair. Later they said that they found that the replaced part had again failed during overnight test and they were repairing the car again. I am concerned that this is a safety issue with the car stalling in the freeway and the component seems to fail easily as demonstrated by the repair that failed again in the dealers shop floor. This issue with Volt needs to be investigated before lives are lost due to improper design/component.

I received the Chevy Volt 2/20/14 at around 10:45 am. My partner and I had a very important meeting at 12:30 P.M. in jersey city, NJ so we left directly from the dealership in the brand new Volt, 7 miles on the odometer. At approximately 12:00 P.M. the car alarmed with two messages: 1. engine not available and 2. propulsion power reduced. The alarms/engine failure came at the most inopportune time---while on the New Jersey turnpike in a construction zone and no available shoulder. With semi-trucks bearing down on us, we luckily made it to a construction pull off area and called on star. On star informed us the turnpike is a restricted zone so they could not send anyone, they were helpful and got in touch with the turnpike authority which sent a tow truck. While I was on the phone with on star my partner called the dealership where we got the car. They were helpful and contacted the dealership where the car would be towed"malouf Chevrolet. After waiting over 30 min for a tow truck to arrive, all the while fearing I was going to be mowed down by a semi-truck on the shoulder, the brand new Volt, my partner and I were off the turnpike. Upon arrival to malouf we were greeted by a member of their service team, he asked me how many miles were on the car. I said?66?, he asked ?6600?, I responded ?no! 66, the car only ran for a little over an hour after delivery!" we now have a loaner from malouf and have not heard anything about what caused this catastrophic failure of the brand new Chevrolet Volt.
