December 9, 2021 Update – General Motors (NYSE:GM) has remedied issues with 10,137 2019-2020 Chevy Silverados dealing with ABS issues. 11 vehicles have been deemed unreachable with additional 2 vehicles being removed from the recall of the Silverado antilock braking system.

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

It’s not the first time that a similar problem has occurred in Chevy vehicles, previously the 2019 Chevrolet Silverado 1500 had been recalled due to problems with the ABS fault indicator lights.

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 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.

Other Chevy Silverado Recalls

Apart from this recall, the 2020 Chevrolet Silverado was among the cars recalled in April 2021 due to airbag failures that failed to deploy properly during car accidents.

Previously In 2020, GM had recalled more than half a million vehicles including the 2020-2021 Chevrolet Silverado Trucks due to seat belt issues in the front-row center seat. General Motors began the recall on February 1, 2021.

Risks 

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 Chevy Silverado 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.
