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."
If a driver is unaware that the ABS system is malfunctioning, there may be an increased risk of a crash.
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.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 'TTY 1-800-424-9153', or go to www.safercar.gov.
