NHTSA Complaint #11543927 — 2010 CHEVROLET SILVERADO 1500

General Motors USA produced several years of vehicles with a faulty transmission control module (TCM). From 2008-25 Chevrolet and GMC trucks with the 6.6L Duramax engine and Allison 1000 transmission all used the same TCM; part 24256861. This part has experienced a very high failure rate. GM has put out Service Bulletins acknowledging this issue and has not made a recall. Safety concerns with the TCM are related to overheating. I have a 2010 Chev Duramax 2500 with that TCM; on July 16, 2022 my truck was taken in for repairs due to the failure of the TCM. For 14 months the truck has been down due to no new parts available from GM and no parts being manufactured in 2022. This has been a substantial impact to me as a consumer. There is a need for new improved parts for this long-standing faulty TCM issue. The lack of recall on this TCM is subjecting consumers to risks of overheating the transmission system as well as incalculable down-time impacts related to personal and business owned trucks. This problem of the faulty TCM on my truck was confirmed by the local auto repair shop I use as well as the local Chevrolet dealership in Delta, CO. The TCM, will long known problems acknowledged by GM, needs to be on a recall for consumer protection.
