General Motors has begun a new customer satisfaction program to address an issue with the transmission range control module in certain 2021 model-year Chevy Bolt EV vehicles.
The problem: in affected Chevy Bolt EV vehicles, the transmission range control module, or TRCM, may be prone to fracturing or breaking.
The hazards: if the transmission range control module fractures, the vehicle may be stuck in park and unable to be put in the forward or reverse drive modes. This does not pose any direct safety hazards to the driver or vehicle occupants, but it can prevent the vehicle from being able to be driven in any way.
The fix: Chevy dealers will be instructed to replace the entire transmission range control module in affected vehicles. These repairs, which will be performed at no cost to the vehicle owner, will remedy the issue and prevent the vehicle from being stuck in park. Only EV certified Chevy dealerships are able to perform this repair. The customer satisfaction program will remain in effect until June 30th, 2023.
Affected components: transmission range control module.
Number of affected vehicles: GM has not said how many vehicles may be involved in this customer satisfaction program.
Owners should: General Motors will notify all owners of affected vehicles and instruct them to make an appointment with their dealer. Owners with questions or concerns can also reach out to Chevy or GM directly using the contact information included just below. These owners may also reach out to the National Highway Traffic Safety Administration with any safety-related questions they may have, though it should be noted this is a customer satisfaction campaign only and not a recall.
