Recalls (4)
General Motors LLC (GM) is recalling certain 2019 Chevrolet Silverado 1500, Cadillac CT6, and GMC Sierra 1500 vehicles. Due to an Electronic Brake Control Module (EBCM) software error, the vehicle's Electronic Stability Control (ESC) and Antilock Brake System (ABS) may become disabled. Furthermore, if this specific error occurs, the vehicle's diagnostics will not illuminate the instrument cluster ESC and ABS malfunction warning lights. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 126, "Electronic Stability Control" and 135, "Light Vehicle Brake Systems."
Risk: If the driver operates the vehicle unaware that ESC and ABS are not functioning, there is an increased risk of a crash.
Fix: GM will notify owners, and dealers will reprogram the EBCM, free of charge. The recall began February 4, 2020. Owners may contact Chevrolet customer service at 1-800-222-1020, Cadillac customer service at 1-800-333-4223, or GMC customer service at 1-888-988-7267. GM's number for this recall is N192268090.
