NHTSA Complaint #11668039 — 2023 CHEVROLET BOLT EUV

Software in the EV system created to protect the battery pack has instead placed my life in jeopardy in response to known false sensor event. During 110 degree heat in isolated desert in southern California, the software detected a false error in high voltage comparisons between battery banks. In response, it disabled climate control, reduced propulsion, and placed an upper limit of 40% on battery recharge system. Without any warning nor noticeable malfunction during the drive out to the desert truck stop, 1 hour of fast charging at 50 kWH resulted in the charger being turned off by the car after reaching only 40%. With no info, I just assumed that this was a failure of the charger; however, I had used this specific charger 1 month prior without any problems. Only after I left this truck stop and headed to the next electric charger, some 50 miles away, did I notice the lack of A/C and warnings on the dash. At this time I called Chevrolet Roadside Service(CRS) and received advice to proceed to the charger then if charging attempt fails, call them back. I drove in 118 degree with open windows behind the slowest moving semi I could find. Within minutes my connected phone for map guidance, started overheating from both the environment and the car charging my phone. I realized I could die out here without car nor phone. Upon arrival, my attempts produced only 4 kWH charging speed at a 50 kWH station. After many false guidances and about 6 calls to CRS and 1 day, I was able to get my car towed to nearby Chevrolet dealer who was too busy to look at the car for 2-3 days. Next day I picked up my car and drove in 102 degree heat to where I purchased this car 2 years ago. 2 days later I picked it up; a known problem solved by a software download fixed it.
