2023 Chevrolet Bolt Euv

The contact owns a 2023 Chevrolet Bolt EUV. The contact stated while the vehicle was in reverse(R), the cross-traffic alert system failed to alert of passing vehicles within 60-ft of the vehicle. The vehicle was taken to a dealer however, the failure could not be duplicated. The manufacturer was notified of the failure. The failure mileage was 100.

Moving at 3mph on slow freeway offramp, my Bolt EUV suddenly braked by itself for no apparent reason. I was at no time in danger of colliding with the car in front of me. However, the driver behind almost rear-ended me when surprised by the sudden braking and sounded his horn. Control Modules scanned at Culver City Chevrolet. No Diagnostic Trouble Codes detected. Problem not confirmed by dealer. An earlier incident of emergency self-braking occurred in May when traversing a speed hump at normal speed where no other vehicles were present. These are the only two instances of self-braking, both unexpected and unnecessary, during the first 5 months/2400 miles of new car ownership. Car is available for inspection upon request.

I drove the vehicle roughly 5 miles on city streets then parked and walked away for roughly 15 minutes. I came back, got in the car, powered it on and attempted to shift but was presented an error message stating “Conditions not correct for shift”. The car seemed to be ‘running’, but the AC did not turn on despite the settings displaying that it was operating. Thankfully I was able to shut down the car after a few minutes and, after waiting a few minutes further, power it back up. This is the first time this has happened to me. Additional details: Mileage: <900 Age: ~2 months At first I thought this could be due to my own behavior. I live in the Southwest (desert). This is possibly the first time I haven’t remotely started the car and let it precondition, but that seems slightly irrelevant given that this happened at night (not baking in the sun) and, before the 10 minutes of rest, the vehicle should have theoretically been ‘conditioning’ during the previous drive.

Frightening SAFETY Problem: Sudden Power loss on Los Angeles freeway. About 6/21/2023 began repeated episodes where my Chevy 2023 Bolt EUV hesitated for a few seconds before responding when I pushed on the accelerator pedal. Full power and acceleration resumed right after the initial hesitation and were sustained until I had to stop the car. A dashboard warning light appeared. I called for an On-Demand Diagnostic evaluation, spoke by phone with Chevrolet support who assisted with the evaluation and emailed me the results (screenshot) indicating an issue with the HCP - Hybrid Control Processor Module and a Diagnostic Code P2797. The Diagnostic Information read: "The Electric Drive Unit is not performing as expected. An issue has been detected in the Auxiliary Transmission Pump System..." The “Recommended Action” was to “Service within 7 days.” (Screenshot) I contacted the dealership where I purchased the car and was told that I would have to leave it for several days before evaluation/servicing could be done. However the next morning (before I could take the car to the dealership) the instrument panel alert had disappeared. So I considered it all a temporary "glitch". Then on 8/27, driving about 60MPH on very busy 405 Freeway in Los Angeles, the car suddenly lost most of its power and slowed down…with an orange dashboard warning icon “Propulsion Power is Reduced” and another message that speed limited to 30 MPH. Alarmed and fearful, I turned on emergency blinker lights, moved to right lane and exited freeway at next off-ramp. The problem persisted as I slowly drove surface streets to destination and parked. Several hours later I started car; alert message came on but car accelerated normally. I slowly drove home on surface streets. On 8/29 another Chevy dealership identified "Scanning Code P2797" and "Replaced Transmission Fluid Pump” by warranty coverage. No problem since. Service manager said she has seen 3 similar problems. I see similar reports online.

Brake lights are too low on vehicle - middle lights are only running lights. Drivers behind vehicle in stop and go traffic must rely on high mounted third brake light mounted at peak of vehicle roof line, especially difficult for larger vehicles (SUVs, Trucks) to see low mounted brakes, with expectation that the middle lights will indicate braking. Multiple reports and complains regarding this issue are posted online and also in this database.

The contact owns a 2023 Chevrolet Bolt EUV. The contact stated while driving 45 MPH, the vehicle lost motive power and shut off without warning. The contact attempted to restart the vehicle however, the vehicle failed to restart. The vehicle was towed to the dealer and the contact was informed that the 12-volt battery was not being used enough and rebooted the vehicle. The vehicle was repaired. The manufacturer was contacted, and a case was filed. The failure mileage was 3,350.

I, and many other owners of Chevy Bolts are having our speed suddenly reduced without warning. The vehicle immediately drops to a max speed of 30 mph and gives an error message "Propulsion Power is Reduced". One common cause seems to be defective transmission fluid pumps, although other electrical and mechanical components also seem to cause this problem. One common error code seems to be P2797, along with the "Propulsion Power is Reduced" message. This dangerous speed reduction is sometimes happening in dangerous situations, while driving in heavy traffic and at high speeds on highways. This is an incredibly dangerous defect and could easily cause car accidents, injuries or death. People are also being stranded without warning. There are many posts (dozens+) about this on various owners groups, including Reddit, Facebook groups and others. The Bolt brake lights and turn signals are also placed in very bad locations which are not obvious or visible, which is also incredibly dangerous.
