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

My 2014 Chevy Volt suffered a complete failure of the EV power system when the battery reached 0 remaining miles. Unlike normal failover to hybrid mode, the vehicle switched into reduced power mode. I was able to drive home (1/4 mile) in this mode but was unable to charge or drive the car after parking it. At this point the car become completely immobile and had to be towed to the dealer (Jerry's Chevolet in Joppa MD). It was there as of December 18. 2023. This is the same behavior as noted in the complaint about Gen 2 Volts except this is a Gen 1 Volt. In the reduced power mode, the car does not accelerate normally and is subject to power surges. The dealer inspected the car and said that a failed cell in the traction battery caused a fault in the entire traction pack. The resulting repair requires a replacement of the battery for $22,000 not including labor! The car is otherwise in excellent condition. I had the SAME issue repaired under warranty in 2021 with the exact same symptoms. If a reasonable battery replacement was offered, I would happily repair the car. Prior to the fault, the vehicle performed normally and even had 39 miles of range (this is nearly original range). I had not indication that the battery may be failing or degraded.

On 2/17/2020, I was driving on I-5 northbound at about 10 pm near burlington, wa. My speed was about 60 MPH on a relatively flat highway. Weather was normal for the time. No rain, no wind. Shortly after my car switched from the electric-powered over to gas-powered, the car started to rev very high and quickly decelerated even though my foot was fully pressed on the accelerator pedal. "propulsion power reduced" message came on, followed by "engine not available, service soon" message came on. The cel also came on. I had never seen these messages before. Semi-trucks were bearing down on me from behind. It was a very dangerous situation. Luckily, I was able to coast to the right shoulder without any car damage or injury. Easily this could have been more serious damage and/or injury if there was more traffic nearby or I stalled in the traffic lanes. I was able to re-start car at about 10 minutes and slowly drove home at a very reduced speed. Subsequently, my car seemed to drive fine. But every time the car goes from electric to gas, I get nervous that this incident will reoccur and cause an accident. Many times, the high rev will start and the "propulsion power reduced" message comes on and the car decelerates but thankfully the car has not completely lost power like the first incident. About 1 month later, I took the car to a chevrolet dealership for diagnostics. The cel went out prior. They could not find any faults and said everything was normal. Nothing was stored in memory. They could not reproduce the problem in the shop. The "propulsion power reduced" message has appeared again after servicing. I am fearful to drive this car.

Tl* the contact owns a 2014 chevrolet volt. While driving in the electric mode, the vehicle's battery voltage suddenly failed and the propulsion system warning indicator illuminated. The vehicle went into its backup mode, which was the use of the fuel generator, and lost power. The contact took the vehicle to dyer chevrolet fort pierce (located at 4200 s us hwy 1, fort pierce, fl) where the hpcm2 system was reprogrammed, which related to the hybrid propulsion system. The failure occurred. The contact stated that the failure was similar to the federal safety agency campaign number: 18v397000 (hybrid propulsion system). The manufacturer was not made aware of the failure. The approximate failure mileage was 105,000. *cw the consumer stated the vehicle has been sold.

I've experienced sudden and complete loss of power steering. It can be temporarily alleviated by turning the vehicle off for serveral minutes, however, the problem will usually persist at some point thereafter. This has happened at both low speeds and at highway speeds.
