General Motors LLC: Electrical System › Software
General Motors LLC reported this defect to federal regulators on May 29, 2020 and put the number of vehicles at risk at 12,200. The repair is free for as long as the recall stands.
The defect
General Motors is recalling certain 2019-2020 Chevrolet 4500HD, 5500HD, and 6500HD Medium Duty trucks. If the vehicle's body control module (BCM) loses communication with the vehicle's electronic brake control module (EBCM), the EBCM software programming may not illuminate the vehicle's ABS malfunction indicator light (MIL). As such, these vehicles fail to comply with Federal Motor Vehicle Safety Standard (FMVSS) Number 105, "Hydraulic and Electric Brake Systems."
The risk
If a driver is unaware that the ABS system is malfunctioning, there may be an increased risk of a crash.
The remedy
GM will notify owners, and dealers will update the software calibration for the body control module (BCM). The recall began June 29, 2020. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N202305070.

What this page is, and what to do next
A recall is not an opinion. It is a Part 573 report a manufacturer is required by federal law to file once it decides a defect poses an unreasonable risk to safety, and it commits them to repairing the vehicle at no cost to the owner. The three passages above are the manufacturer’s own wording as published by NHTSA.
This page describes the campaign. It cannot tell you whether one particular car has already been through the shop — that is tracked by VIN, and only the manufacturer knows it. Check yours at nhtsa.gov/recalls or with a franchised dealer, quoting campaign number 20V319000.
