Cadillac Recall 24V-674: Service brakes, hydraulic

The problem

General Motors, LLC (GM) is recalling certain 2023 Chevrolet Silverado 1500, GMC Sierra 1500, 2023-2024 Chevrolet Tahoe, Suburban, GMC Yukon, Yukon XL, Cadillac Escalade, and Escalade ESV vehicles. The electronic brake control module software may fail to display a warning light when a loss of brake fluid occurs. As such, these vehicles fail to comply with the requirements of Federal Vehicle Safety Standard number 135, "Light Vehicle Brake Systems."

The 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.

The 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.
