General Motors is recalling over 449,000 SUVs and pickup trucks due to a potential issue with the electronic brake control module software, which may fail to activate a warning light in the event of brake fluid loss.
The National Highway Traffic Safety Administration (NHTSA) announced in September 2024 that the recall covers specific models, including the 2023-2024 Cadillac Escalade and Escalade ESV, 2023 Chevrolet Silverado 1500, 2023-2024 Chevrolet Tahoe and Suburban 1500, 2023 GMC Sierra 1500, and 2023-2024 GMC Yukon and Yukon XL.
The NHTSA stated that without the warning light, a vehicle could be operated with low brake fluid, potentially reducing braking performance and increasing the risk of a crash.
A free software update will be provided to vehicle owners.
