2012 Chevrolet Volt: sudden loss of power

Filed Dec 27, 2022 · Electrical, Fuel system · ME

2012 chevrolet volt, the vehicle has been losing power for propulsion on the highway/roads at all speeds. Shutting off. Electric charge is supposed to switch to the gasoline motor when it is low, but it does not, and vice versa. It shows hybrid battery management has a loss of propulsion with a message of low propulsion power. The original problem was not fixed with a recall a few years back because the same problem is showing up. Now, chevy does not have this VIN being recalled. But worse, the conditions in the software are causing a powertrain failure while driving. Please help. I am pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

I'm constantly receiving a "Propulsion Power Loss" notification on my car. I have brought the car in to a Chevrolet dealer and they refuse to fix it unless I start paying out of pocket costs because the ticket is "closed". This has been going on for about a year since I purchased the car last November and I'm terrified to drive this car since it literally looses power.

While driving sudden loss of power having to basically depress gas pedal to maintain speed while simultaneously receiving "reduced propulsion error". Dealer cleared error and did a reprogram. After picking up vehicle range was reduced approximately 1/3rd but car ran. Shame on me for not being more forceful about range reduction because this battery was defective. This summer june 2020 complained about reduced range and dealer did more programing. Now in october 2020 reduced propulsion error came back and hybrid battery is bad. Warranty ran out in may 2020 and gm refusing to acknowledge 2018 date of defective battery.

Volt loses power when switching from battery to gas. Has now occurred four times. Each time volt is traveling on highway 65+MPH. Volt depletes battery charge and immediately upon transition to gas will lose all power. Cannot accelerate. Steering wheel loses power steering. Volt will decelerate until 0 MPH. Very dangerous. In each instance driver is forced to get to shoulder or off freeway in volt which is rapidly losing speed. Occurred on highway without shoulder last time. Almost caused a serious accident.

Vehicle dies suddenly while moving, although under full electric charge. Could not restart. Chevy said was software problem and made fix dec 2018. Just happened again yesterday 2/17. Others reported on volt blog site. Said wait 5-10 minutes and then restart, which I did and that worked. Concern that loss of power is sudden and without warning. Died in middle of intersection this time but fortunately no cross traffic. This is serious problem -- apparently others have had same issue. Reporting to local chevy dealer at this time.

Driving using cruise control during commute at 60mph. Simultaneously experienced drastic power loss and check engine light. Onstar diagnostics reported an electrical propulsion system malfunction. Attempted to navigate to a safe parking area but eventually lost all propulsion and ended up in a traffic lane. Significant impact to control especially in highway traffic that nearly resulted in a collision.

On 5-21-14 I was driving 25 MPH when I had to do an panic stop to avoid another car. At this point the car lost all power and my brakes went to floor. I missed hitting the other car by inches. Once I restarted the volt it came up with a dash warning to "service brakes". I drove about 20 MPH for 1 mile to find a safe place to pull over and park. All the while testing my brakes and they were very mushy. Once I pulled over and stopped another warning message came up on dash saying "ABS failure". I called aaa and had car taken to dealership. It has now been at dealership for 21 days and still counting without even one update from dealership. Once at dealership the car acted normal as if nothing was wrong.

When I turned on the vehicle the touchpad showed no A/C. I started to drive the vehicle and approximately 5 miles the heater came on and blew hot air, then after awhile the A/C came on. After accelerating from a stop when I reached approximately 45 MPH the vehicle lost power and the steering wheel locked up. I could not control the vehicle. Then the vehicle jolted and the power returned. This has happened prior and was taken into chevy dealership for repair. Loosing power and steering capability is not safe.

While I was driving home my car would surge then lose power. I pressed the onstar button and a vehicle test was conducted. I was told the transmission needed attention. Also, the vehicle lost power while driving and I had to pull off the road. I was on a rural road so no one else was affected. Had I been on the interstate this could have affected others and myself in a negative way. I took the vehicle in and jessup auto in catherdral city, ca kept it several days and corrected the issue. The main issue is losing power while driving.
