GM Recalling 450,000 Trucks, SUVs That Fail to Issue Brake Fluid Warning

• General Motors is recalling nearly 450,000 trucks and SUVs with a potentially faulty brake fluid warning light.

• According to the National Highway Traffic Safety Administration, the brake control module may fail to display a warning when brake fluid is low.

• The recall covers some 2023 Chevy Silverado 1500 and GMC Sierra 1500 trucks and 2023 and 2024 Chevrolet Suburban and Tahoe, GMC Yukon and Yukon XL, and Cadillac Escalade and Escalade ESV models.

General Motors issued a recall that spans 449,671 trucks and SUVs with a potentially faulty brake fluid warning light. According to documents filed with the National Highway Traffic Safety Administration (NHTSA), the recall includes some 2023 Chevy Silverado 1500 and GMC Sierra 1500 trucks, and 2023 and 2024 Chevrolet Tahoe, Suburban, GMC Yukon, Yukon XL, Cadillac Escalade, and Escalade ESV models.

The recall documents show that the brake control module may fail to warn the driver of brake fluid loss before brake performance degrades. A mismatch between the brake control software and the brake control calibrations reportedly causes the failure.

Dealers will issue a software update to the affected vehicles to match the brake module software with the correct calibration. Vehicles capable of receiving over-the-air updates will be able to receive the fix from home, while owners of non-OTA-equipped vehicles will have to visit their dealership for the update.

Dealers were informed of the recall on September 12, and GM will notify owners by mail starting on October 28. Owners can also check the NHTSA recalls website beforehand to see if their vehicle's VIN is involved in the recall.
