2015 Chevrolet Volt electrical problems

Filed Nov 14, 2025 · Electrical, Engine · FL

My 2015 Chevy Volt has been experiencing ongoing mechanical and electrical issues, including random power loss, reduced propulsion warnings, and sudden vehicle shutdowns with no prior indication. These problems pose a serious safety concern, as the car can lose power unexpectedly while driving. Despite these issues, GM has refused to service the vehicle or unlock necessary components because they no longer manufacture or support the required parts. As a result, I am left with an unsafe and unreliable vehicle with no available remedy from the manufacturer. This is forcing me to trade in the vehicle at a loss

The car has not been able to charge since April of last year. I have taken it to the dealer to diagnose but they want to charge $200 per hour to diagnose. They already suggested that the charge receptacle should be replaced. I purchased the part and replaced it myself. I have tried asking if it could be the BECM like with other model years and they said they could only determine that after testing and replacing parts. The P1EE6 error code suggests that the BECM might need to be replaced and/or reprogrammed. There have been several times that I have experienced a loss of propulsion error while driving. I know there is a safety bulletin for the 2016-2019 models year that I think should apply to other model years.

I will be driving on the road and randomly my vehicle will give me a loss of propulsion warning. This has happened many times on the highway where I’ve lost acceleration power quickly and have almost been involved in a futile accident as a result. My vehicle also randomly switches from electric to gas sometimes causing my car to jolt

This car is connected to Bouncie a device that detects when a car turns on and off, the speed, if break or acceletor are stepped on forcefully and any trips. Recently the device is detecting the engine is turned off but the car is showing no signs of struggling and its in full motion. This is new, I've tested the device in another car for two weeks hoping it was the device but I had no issues on the other vehicle. The images is just one of several occasions. The image shows green dot where car starts and red where car is turned off. However, I never turned off my car at the Demaree Rd that day. I feel like the car is losing power and starts back up while in motion.

I was driving on a road at roughly 50 mph when suddenly without warming, the screen and everything shut off and went black in the vehicle, and then immediately turned back on, this time with the engine light on. In the following seconds, the gas pedal completely stopped responding, and I had to coast to a stop at the side of the road. It was a dangerous spot on the road to have this happen. I was able to power the vehicle off, and then back on again, and the vehicle functioned normally immediately afterwards, with no engine light on.

Driving 75mph with cruise control during moderate traffic on freeway about 30 minutes after starting the car, my Volt shut off. There was a jolt of the car that felt like strong breaking and my dash along with everything electrical shut off for about 2 seconds then kicked back on with "Service Theft Deterent" on dash. I could not break or steer the vehicle. I had to come to a rolling stop on shoulder of freeway. Luckily I was in toll lane #1 next to the shoulder or I might have been in a wreck with other cars. I have a check engine light on now and a scheduled appointment at Chevy dealer made prior to today for tomorrow. I have had an issue with my Volt not charging at home/work for a few weeks. No breakers pop, the vehicle just wont complete the charge. The battery was replaced a week ago, driven over 250 miles with new battery, and it is still not charging properly. I have no messages on my vehicle regarding battery, engine, etc. Just the check engine light lit up.

Driving on 55 MPH straight two lane road when car ahead slowed. To recover energy to the battery, dropped from "d" to "l" in gear selection rather than using brakes (was plenty of distance, but not enough to coast). Car in front turned off to right. I advanced selector to drive, but overshot into neutral. Realized my error when pressing accelerator yielded no speed increase. Put selector into "d", verified visually and pressed accelerator without result. Verified again visually that selector in d. Advanced deliberately into n, then back to d, then reapplied accelerator with functional result this time. I am a pe with siemens vdo, retired. Since vehicle is single speed "transmission", I assume computer glitch

While driving on the highway the instrument cluster went blank and turned off. This houses information like warnings, speed, fuel level, battery level, traction, navigation, odometer, light signals and other information. This is a huge safety issue while traveling down the road and losing your ability to look at the speed or if your blinkers or lights are on.
