- GM is recalling 450,000 trucks and SUVs because of a brake fluid warning light malfunction.
- The issue affects the Chevy Silverado, Tahoe, and Suburban, along with several GMC and Cadillac models.
- A software update will resolve the faulty brake fluid warning issue in affected GM vehicles.
GM is recalling nearly 450,000 pickup trucks and SUVs in the United States as their low brake fluid warning light may not work. Although GM says affected vehicles will still meet stopping-distance requirements in the event of a brake fluid leak, vehicles still need to be fixed.
The carmaking giant says that a mismatch between the electronic brake control module (eBCM) software and eBCM calibrations means the brake fluid warning light may not illuminate when a leak starts, as it should. Consequently, brake performance may degrade before the light is illuminated, increasing the risk of a crash.

GM notes that the warning light will still function before a total loss of brake fluid.
In total, 449,671 vehicles in the United States are impacted by the recall. These include 2023 Chevrolet Silverado 1500s built from January 4, 2023, to April 27, 2023, 2023-2024 Chevrolet Tahoes built from October 28, 2022, to July 24, 2024, 2023-2024 Chevrolet Suburbans manufactured from October 28, 2022, to July 24, 2024, and 2023 GMC Sierra 1500 models made from January 11, 2023, to April 26, 2024.
Other vehicles impacted by the recall include 2023-2024 GMC Yukons assembled from October 28, 2022, to July 24, 2024, 2023-2024 GMC Yukon XLs made from October 28, 2022, and July 24, 2024, 2023-2024 Cadillac Escalades built from October 28, 2022, to July 24, 2024, and 2023-2024 Cadillac Escalade ESVs built from August 19, 2022, to July 24, 2024.
A GM engineer first recognized the problem on April 18, 2024, and submitted it to GM’s internal Speak Up For Safety program. GM doesn’t know of any crashes or injuries related to the fault.
Owners of impacted models will be notified of the recall from October 28. A software update can be performed by dealerships to rectify the issue, while applicable models that support over-the-air updates will be fixed remotely.
