NHTSA Complaint #11544123 — 2023 CHEVROLET BOLT EUV

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.
