NHTSA Complaint #11533046 — 2020 CHEVROLET BOLT EV

Although the NHTSA website now reports that my vehicle is longer the subject of a safety recall, NHTSA Campaign Number 21V650000 was not resolved by the software update that Chevrolet installed on my vehicle on June 26, 2023. The high voltage battery on my car failed only 65 miles after the new software was installed. When the newly installed software detected a problem with my car's high voltage battery, the driver information screen on the car's instrument panel advised me that "propulsion power is reduced" and "service vehicle soon." That prompted me to return to my dealer's service department. The dealer that sold me the car and performed the "reprogram field action multimodules coordinated sequence" on June 26 informed me on July 10 that the high voltage battery needs replacement and cannot now be recharged. However, neither the dealer nor Chevrolet can specify a date by which the required battery replacement can and will be completed. I have been told that necessary replacement parts will not be available for "weeks or months." In my case, Chevrolet addressed the risk of fire that prompted NHTSA Campaign Number 21V650000 by confirming the problem and then rendering my car inoperable. I do not believe that NHTSA would consider that an effective response to the recall.
