7/6/2024 Was driving 45 mph on a busy road (running only on the gas engine of this plug-in hybrid). Propulsion Power Reduced message showed near the speedometer. My speed was immediately decreased. The check engine light also came on. Despite pressing the gas pedal, the speed could not be maintained and I had to pull off quickly before causing an accident. Luckily, no accident occurred but I fear would could have happened if I wasn't in the right place to pull over quickly. After getting the car towed to a Chevy dealership, they diagnosed the problem as being with the hybrid battery - it needs to be replaced. I don't understand why I had a full tank of gas, was running on gas, and that a bad EV battery would cause ALL propulsion to stop so quickly.

This is a report on a previous safety recall that has failed to fix the problem. The recall is GM Program # N172130462 for sudden-onset reduced propulsion. The recall repair was performed on this vehicle at 91,064 miles. However, since the recall, a reduced propulsion condition has recurred multiple times. Subsequent to the most recent episode, the vehicle has been in the dealer's repair shop for 5.5 months. The dealer technician affirms it is a software problem, but is unable to figure out how to repair it, even with assistance of a General Motors field engineer. The dealer technician told me that the GM field engineer knows of other cars with the same problem.

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).

Driver's side front wheel began making extremely loud whining-like sound while highway driving. Parked the car until it could be accepted at the certified chevrolet service department at a local dealership. Technician immediately diagnosed the problem and expressed it as "common." the issue is a separation of the "electric driver motor b rotor bearing cage" requiring a revised bearing installation. This is clearly a design flaw as gm requires a new/revised bearing installation, and is likely progressed with the vehicles regenerative braking. Gen1 models do not have a customizable regenerative braking option to alleviate this stress on the rotor bearings. In researching the issue, the service bulletin provided by gm is has progressed to an appended letter l (bulletin no. Pip5081l). A large number of volt owners share this experience, many of which qualify for warranty repair. My vehicle's warranty period expired by less than one year and 11,000 miles.

My car has had ongoing problems with power propulsion, electrical system, and start-up since new and several items were replaced in 2017. I purchased 6 year / 100,000 extended warranty when new. Several items have been replaced. But updates are needed to keep the car running properly. Now the warranty has expired but the vehicle still needs updates to run properly and the dealer wants paid to install updates. This is a scam if the car wont run with out being updated yearly. I have a video of the car in 2017 when I started it up and it sounded as though it was going to blow up. I couldn't shut it off and called onstar to shut off the vehicle. That is when several items were replaced. The car is in the dealership again for another update. 8-28-20. There was an updated performed 11-11-19 and 10-10-18. It seems as though there is always an update being performed.

My 2012 chevy volt has completely shut off at freeway speeds, and surface streets on over 15 occasions. The power steering assist goes out, the brake assist goes out and it's very difficult to steer and break the car, I have nearly avoided several accidents, there is no warning that this will occur.the power steering assist goes out, the brake assist goes out and it's very difficult to steer and break the car, I have nearly avoided several accidents, there is no warning that this will occur once I have attempted to safely pull over the car says engine not available, propulsion power reduced, the car will not turn off and it says waiting to initialize on the screen. I have had it towed to my local chevrolet dealership and paid a diagnostic, they have been unable to determine the cause of the problem and they just reset the car by unplugging the battery and tell me that they cannot replicate the issue.this does not happen while the car is driving on his hybrid battery, it only happens when driving in hybrid mode with the gas motor. In doing my own research, I found a recall campaign that describes the exact issue that has been occurring, it even states that the car may not be safe to drive if this occurs. Recall #18v397000. Each time I towed my chevy volt to the dealer it sat there for several weeks to a month, they returned it to me and the next day it died in the road. The car is not safe to drive, the dealer states that they can't diagnose the problem and I fear for my life every time I drive the car because it happens at random.

The drive motor rotor bearing failed at approximately 71,000 miles. This major repair to the drive train makes the car unusually loud and the dealer cautioned that it was a safety hazard and that if left in repaired could cause more substantial damage to other vehicle components.
