2014 Chevrolet Volt Complaints

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 de...

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...

The car stopped working at a stoplight while I was driving my son to school. There was no warning other than a "Propulsion power is reduced" message seconds before it stopped working. After turning it off and back on, I got the car to limp out of traffic. By the time the tow truck arrived an hour later, we could barely get it to go into neutral to tow it. After towing it to the dealer, they replaced the engine control module. Since then, it has been working fine.

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.

Early this year GM disabled the OnStar feature on all Chevrolet Volts that have 2G connectivity. GM offered Canadian owners the option to upgrade their Volt's from 2G to 4G. In September 2019 they issued Service Bulletin 15-08-44-001J that gives the GM service department instructions on how to upgrade the Volt from 2G to 4G connectivity. They should give us the same options here in the states!
