The National Highway Traffic Safety Administration (NHTSA) and General Motors are recalling certain 2019 Chevrolet Silverado 1500 and GMC Sierra 1500 pickup trucks due to a problem with the vehicles’ electronic brake control module (EBCM).
The defect: this recall is related to a 2019 recall that GM issued for over 460,000 Silverado, Sierra and Cadillac CT6 vehicles. Vehicles included in that recall left the factory with faulty EBCM software that may cause the anti-lock braking system (ABS) and electronic stability control (ESC) to become disabled. As we reported last week, the fix for the problem was a dealer-installed reflash of the EBCM software, however, the software update from the first recall can disrupt the electronic brake control module when the vehicle is started using the OnStar app, so it must be re-programmed once again. The NHTSA filing did not go into detail, only saying the “software has an error, and as a result, the vehicle’s electronic brake assist may be disabled.”
The hazards: a loss of electronic brake assist can lead to reduced braking performance and increase the risk of a crash.
The fix: GM says dealers will re-flash the EBCM software. These repairs will be done at no cost to the owner.
Affected components: EBCM, EBCM software.
Number of affected vehicles: a total of 148,055 vehicles are affected by this secondary recall.
Owners should: GM will notify owners of affected vehicles and instruct them to make an appointment with their dealer. The recall is expected to begin on February 10th, 2020. If owners are unsure whether or not their vehicle is affected, they can visit my.gm.com/
