May 29, 2020 · General Motors LLC
Problem
General Motors is recalling certain 2019-2020 Chevrolet 4500HD, 5500HD, and 6500HD Medium Duty trucks.

Safety risk
If a driver is unaware that the ABS system is malfunctioning, there may be an increased risk of a crash.
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.
