FORWARD COLLISION AVOIDANCE: WARNINGS
Potential Consequences:
Consistent BCEM failure with volt. Power Reduced even if battery has full charge and gas is in tank. Forward Collision made unavailable without reason whilst driving. I rely on the forward collision system while driving at night in my area because of drivers cutting each other off constantly, so losing this feature without knowing why it failed feels unsafe to me. Forward collision would also activate when no vehicle is infront of me causing the car to suddenly stop and jerk on the road. Propulsion power is reduced is an extremely common occurrence in my volt. It happens randomly while driving and even while charging. When I'm on the highway the car would slow down when the warning came on; even with cars right behind me. I'm scared one day the car's system will cause an accident because of it's unpredictability. Regular maintenance has been performed and no issues have been found. The problem continues to persist.

VEHICLE SPEED CONTROL
Potential Consequences:
On 3/11/2023, I was heading home when my vehicle lost power in the middle of the freeway. Luckily, I was able to safely pull over to the side of the freeway. Since this is a plug-in hybrid, there are two gauges showing how much electric and gas is in the car. When I checked, both showed were empty; however, although I knew that I did not have much electricity in the battery, I had nearly a full tank of gas. The vehicle should have had automatically switched over to the gas but did not. After a few minutes of leaving the car off, I was able to restart the vehicle in gas mode and drive home safely. I brought in the vehicle to my local Chevy dealership to have it diagnosed. It was determine that the computer had registerd multiple faults p0030, 31, 54, 135, 403, 405, 443, 458 and 537. They also found TSB 21-NA-116. They had found that the 15 AMP fuse was blown. They had to replace the EGR valve assembly. Total time was 2 weeks to repair as they had to wait for the parts from Chevy. Per WO, parts 12346290 (Coolant) and 12691147 (Valve) were replaced. After replacement, vehicle have been running fine for the past 9 months. Prior to the engine shutting off, there was a message on the screen while driving which says "Propulsion Power is Reduced". The electric gauge was empty but the gas tank show nearly a full tank.

ELECTRICAL SYSTEM
Potential Consequences:
The car regularly reports it is healthy and functioning correctly. It is regularly serviced and there was no advance warning of this problem. While driving the car displayed a message to the driver, something such as "reduced propulsion" and the speed of the car was reduced while the internal combustion engine intermittently raced in an uncharacteristic manner. The amber Check Engine light was displayed. A review of error codes later found a communication fault developed with the Battery Energy Control Module (BECM). As soon as it was possible, we got the car to the side of the road and shut it off. We then attempted to start the car and it displayed a warning that no key fob was present (but there was a key fob in the car). A few minutes later the car started and we were able to drive it to a service center where error codes were captured. Afterwards, the car drove as normal, and later even the amber Check Engine light was extinguished. The service center explained this could be an intermittent problem where the car will suddenly throw the error message ("low propulsion") and the car will have to be pulled to the side of the road. It will be a few weeks before the service center can do any work on the car. Since the car may start and drive, but suddenly find its speed reduced to far below the speed limit, the car can no longer be safely operated.

Defect Description:
ENGINE
Potential Consequences:
While driving to work, the vehicle shook a bit and entered into "reduced propulsion mode". The vehicle had a significant reduction in engine power on the road (the propulsion became very jerky), which became dangerous on the highway. There were no previous indicators of any type of issue. After brining the vehicle to the dealership, I was told it would be okay to drive until my appointment (which was scheduled for the subsequent week). Two days later, the vehicle would not start. When attempting to start the car, the "Shift to Park" message displayed. I had to get the vehicle towed to the dealership at that point. The dealership mentioned it is likely an issue with the Battery Energy Control Module (BECM). However, I'm still waiting for a resolution.
Corrective Action:
While driving to work, the vehicle shook a bit and entered into "reduced propulsion mode". The vehicle had a significant reduction in engine power on the road (the propulsion became very jerky), which became dangerous on the highway. There were no previous indicators of any type of issue.

FUEL/PROPULSION SYSTEM
Potential Consequences:
The battery energy control module failed mid drive causing my car to come to a stop in the middle of traffic. The car was towed to a dealership mechanic shop where the BECM had indeed failed. There was no signal that is was going to fail it just simply stopped and as it stopped the check engine light came on

ENGINE
Potential Consequences:
Around the tenth of November my car, a 2017 Premier Volt bought used, began to display an information message that the propulsion power is reduces. It displayed 0 mi EV range, even though I knew I had some left. When I started to drive the engine seemed louder than usual and the check engine light was on. I pulled into a parking lot, and checked under the hood just to make sure nothing was obviously smoking or sparking. I turned the car on and off, and drove around the parking lot a few times until it resumed normal functionality, however the check engine light remained. This was after dark, when I got off work, and I drive home on Highway 49. I did not want to drive it home on the highway in the dark until the issue seemed resolved. Since the manual claimed that if I see both reduced propulsion and check engine light I should immediately take the car to my dealer, I made an appointment with them for the sixteenth of November. For the next couple days I continued to have the same issues, propulsion reduced, incorrectly displaying 0 EV miles, and the check engine light coming on. Starting and stopping the car, or driving around the parking lot a couple times seemed to temporarily solve the issues. At the dealer, I was told there is no ETA on the part, and that it is back ordered or wait listed. The issue is with the BCEM or battery energy control module. They provided me with a rental car for the time being. A few weeks have passed, so I called them today, the 11th of December, but there is still no eta. They are still waiting for the BCEM, which is back ordered.

FUEL/PROPULSION SYSTEM
Potential Consequences:
On 2 separate time periods, "propulsion power reduced" message appears on dash: - 1st incident in November 2022, car would not move after powering off the vehicle. After sitting idle for a week, decided to retry, and car seemed to work normally. Took it in to Chevy service, they replaced the BECM. Car worked fine after this - 2nd incident in November 2023, again 'propulsion power reduced' message appeared. This time, however, car would suddenly cut off gas engine (even at highway speed), switching to 100% battery mode, and displaying 'Engine not available' on dashboard. Fuel level indicator would immediately display 'LOW' (even though gas tank was full). Reduced acceleration on battery mode. Car is now in same service center awaiting fix for the past month. Was quite an unsafe situation, especially at highway speeds, and especially given the fact that the battery also may have been at a low state of charge, risking complete vehicle breakdown. Coupled with both of these incidents, the cruise control intermittently shuts off, displaying 'Cruise control unavailable'. Car is lightly utilized, with just over 30k miles on the odometer to date. Additionally, the car is kept in a mild climate (coastal southern california) and parked in a covered spot shielded from sun and temperature extremes.
