Risk: Wheel lock-up while driving increases the risk of a crash.
Fix: Dealers will install transmission control module monitoring software, free of charge. Owner notification letters were mailed April 7, 2025. Owners may contact Cadillac customer service at 1-800-333-4223 or Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N242480630.
Service brakes; electronic stability control (esc); service brakes, hydraulic:antilock/traction control/electronic limited slip:abs warning light
Problem: 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.
Exterior lighting:turn signal:switch
Problem: General Motors LLC (GM) is recalling certain 2019 Cadillac CT6 vehicles. Rotation of the steering wheel will not automatically cancel the turn-signals from flashing. As such, these vehicles fail to comply with Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices and Associated Equipment."
Risk: If the turn-signals do not automatically deactivate, the driver may fail to turn them off manually. An erroneous active turn-signal may mislead pedestrians and other drivers, increasing the risk of a crash.
Fix: GM has notified owners, and dealers will replace the turn-signal switch. The recall began March 11, 2019. Owners may contact Cadillac customer service at 1-800-458-8006. The Cadillac number for this recall is N182207090.
Seat belts:rear/other
Problem: General Motors LLC (GM) is recalling certain 2018-2019 Cadillac CT6, Escalade ESV, Chevrolet Suburban, Volt, and GMC Yukon XL vehicles. Certain second-row or third-row rear seatbelts retractor assemblies may not automatically lock when the seatbelt is fully pulled out of the retractor, possibly preventing a child seat from being properly secured. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."
Risk: If the child seat is not properly secured in the event of a crash, it can increase the risk of injury.
Fix: GM will notify owners, and dealers will inspect the rear seatbelt retractors and replace them if necessary, free of charge. The recall began November 7, 2018. Owners may contact Cadillac customer service at 1-800-458-8006, Chevrolet customer service at 1-800-222-1020 or GMC customer service at 1-800-462-8782. GM's number for this recall is 18315.
