What is wrong

General Motors, LLC (GM) is recalling certain 2022-2023 Chevrolet Express and GMC Savana vehicles. Incorrect software in the transmission control module (TCM) may result in harsh shifting, reduced power, unintended deceleration, rear wheel lockup, or cause the vehicle to move in an unintended direction.

What can happen

Rear wheel lock-up or moving in an unintended direction can increase the risk of a crash.

Dealers will update the transmission control module software calibration, free of charge. Owner notification letters were mailed December 9, 2024. Owners may contact GM customer service at 1-888-988-7267, Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is N242471620.
