GM Recalls More Than 400,000 Vehicles Over Electronic Brake Control Problems

According to an Associated Press report, General Motors is recalling more than 400,000 pickup trucks and cars in the U.S. to fix problems with the electronic brake controls.

The recall covers nearly 464,000 Cadillac CT6 sedans and Chevrolet Silverado 1500 and GMC Sierra 1500 pickup trucks from 2019. According to the National Highway Traffic and Safety Administration’s voluntary recall with GM, there is a software error that can disable the electronic stability control and antilock brake systems.

The Problem…

A software error in the electronic brake control module may disable both the anti-lock brake system and the electronic stability control system. The software glitch could also prevent the instrument-cluster warning lights from illuminating and alerting drivers about the issue( meaning that the vehicles don’t comply with key provisions of the Federal Motor Vehicle Safety Standards). NHTSA says that if drivers don’t realize there’s a problem, and they attempt to operate the vehicle in this condition, they could be at an increased risk for a crash. 

One of the reported complaints stated that when the vehicle owner was driving 60 mph, the check engine, stability control, traction control, and ABS warning lights came on. Also, the dash displayed “limited to 62 mph” and the vehicle would not respond when the brakes were applied. The owner had to downshift manually to stop. OnStar was called and codes 925A2, P0606, and C0021 regarding the ECM, charging system, airbags, and transmission were detected.

The Fix…

GM dealerships will reprogram the vehicle’s Electronic Brake Control Module, the root of the problem, at no charge.
