Tough But Complicated
Most of GM’s success comes from sales of the auto giant’s full-size pickups: the Chevrolet Silverado and GMC Sierra. These two trucks compete in one of the biggest segments in the U.S. and are known as tough, dependable mobility options for work and play. Alas, modern mobility strikes again, as technology falls short in this particular case.
An issue has come up with the Silverado and Sierra, and what seems like a minor issue at first actually has bigger implications once you understand it fully.
Brake System Warning Issue
GM Authority reports that select 2024 Silverado and Sierra models have a problem with the brake system malfunction indicator light. GM issued a recall explaining the issue, which stems from a faulty Brake System Control Module (BSCM). Apparently, the module that was installed in the affected trucks doesn’t set a Diagnostic Trouble Code (DTC) or turn on the Malfunction Indicator Light (MIL) when the system detects a fault.
Another issue is that it may also affect the vehicle’s emission control system. This matters because, if the car has a faulty brake system the driver isn’t aware of, it could affect drivability and pose a safety risk to passengers and other motorists. GM says that the fix is relatively easy; dealerships and technicians just need to reprogram the Brake System Control Module, which will take 30 minutes to complete.
The Finer Points
The recall affects the 2024 Chevrolet Silverado 1500 and the 2024 GMC Sierra 1500. GM also says that vehicles that still sit in lots and remain unsold must have the fix performed before selling the trucks to customers. Surprisingly, the recall doesn’t specify how many trucks are affected. Owners who may own an affected vehicle should check official GM channels for a proper diagnosis.
