General Motors has issued a recall affecting nearly 450,000 trucks and SUVs due to a potential brake fluid warning system defect. The issue centers on the vehicles’ brake control module, which may fail to alert drivers when brake fluid levels are dangerously low, posing a serious risk to brake performance and overall vehicle safety.
History Behind the Recall
The National Highway Traffic Safety Administration (NHTSA) identified this problem after a GM engineer discovered the brake fluid warning light, known as a “telltale,” failing to activate during a forced brake fluid leak test in April 2024.
Upon further investigation, GM found that the issue stems from a mismatch between the electronic brake control module (eBCM) software and the calibrations installed in the vehicles at the assembly plant. This mismatch prevents the system from detecting and displaying the brake fluid warning when necessary.
While no crashes or injuries related to the issue have been reported, the risk of brake fluid loss without warning could significantly reduce braking performance, putting drivers and passengers in danger.
Which Models Are Affected?
The recall affects a broad range of GM vehicles from the 2023 and 2024 model years, including:
- 2023 Chevrolet Silverado 1500
- 2023 GMC Sierra 1500
- 2023-2024 Chevrolet Tahoe
- 2023-2024 Chevrolet Suburban
- 2023-2024 GMC Yukon
- 2023-2024 GMC Yukon XL
- 2023-2024 Cadillac Escalade
- 2023-2024 Cadillac Escalade ESV
In total, approximately 449,671 trucks and SUVs in the U.S. and 38,390 vehicles in Canada are impacted by the recall.
What Owners Need to Do Next
GM will begin notifying owners of affected vehicles by mail starting on October 28, 2024, instructing them on how to proceed. The solution involves a software update that corrects the mismatch between the brake control module software and the calibrations.
Owners whose vehicles are equipped with over-the-air (OTA) software update capability will be able to receive the fix remotely without needing to visit a dealership. For those without OTA-equipped vehicles, GM recommends scheduling an appointment with their local dealer to have the update installed.
