Chevrolet Silverado Pickup Trucks Recalled for Faulty ABS Indicator Light

Pleasanton, CA – July 17, 2020 – General Motors (NYSE:GM) has recalled 12,200 Chevy Silverado trucks that may fail to indicate to the driver that there is a problem with the car’s anti-lock braking system (ABS), increasing the risk of  a crash. The recall includes:

  • 2019-2020 Chevrolet 4500HD Silverado Medium Duty trucks
  • 2019-2020 Chevrolet 5500HD Silverado Medium Duty trucks
  • 2019-2020 Chevrolet 6500HD Silverado Medium Duty trucks

Recall summary  

On May 29, General Motors decided that certain 2019-2020 Chevrolet   Medium Duty 4500HD/5500HD/6500HD trucks do not comply with a federal regulation requiring the ABS light to illuminate during certain kinds of malfunctions.

Vehicles use several control modules to operate many aspects of the car. GM houses many of these modules together in a grouping called the Body Control Module (BCM), which coordinates many functions in the vehicle, including as the speedometer, the instrumentation panel and the chime warnings.

Another module, called the Electronic Brake Control Module (EBCM), reads sensors in the braking system, and uses that information to activate the ABS as needed for sudden braking, stability or traction control. These two systems need to communicate for the safety of the driver.

In the recalled vehicles, the ABS light fails to illuminate when the BCM can’t communicate with the EBCM. This means that the driver will not be notified when there is a problem with the ABS.


It is important for drivers to know if there is a problem with the anti-lock brakes. Driving without the ABS, particularly in bad weather, can be dangerous because the vehicle may not handle braking on slippery surfaces the way it is supposed to.

When a vehicle skids, the tires lose traction with the ground and the driver can no longer steer, increasing the risk of a crash.

The repair

The affected trucks need a software update for the BCM. The update itself should take approximately 35 minutes, but GM advises owners in its owner notification letter that it may take longer “because of service scheduling requirements.”

The repair is available now and is free of charge.
