As such, these vehicles fail to comply with the requirements of Federal Vehicle Safety Standard number 135, "Light Vehicle Brake Systems."
Risk: Without a warning light, the vehicle may be driven with low brake fluid, which can reduce braking performance and increase the risk of a crash.
Fix: The Electronic Brake Control Module (eBCM) software will be updated through an over-the-air (OTA) update or by a dealer, free of charge. Owner notification letters were mailed October 25, 2024. Owners can contact GMC customer service at 1-800-462-8782, Chevrolet customer service at 1-800-222-1020, or Cadillac customer service at 1-800-458-8006. GM's number for this recall is N242447990.

Model years: 2019
Problem: General Motors LLC (GM) is recalling certain 2019 Chevrolet Silverado 1500, Cadillac CT6, and GMC Sierra 1500 vehicles.

Problem: General Motors LLC (GM) is recalling certain 2015-2020 Chevrolet Suburban, Tahoe, and GMC Yukon, and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system.
Risk: Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash.
Fix: GM will notify owners, and dealers will reprogram the EBCM, free of charge. The recall began December 11, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192261050.
