General Motors is recalling approximately 12,200 model-year 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."
GM will notify owners, and dealers will update the software calibration for the body control module (BCM). This recall is expected to begin July 13, 2020. Owners may contact Chevrolet customer service at (800) 222-1020. Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at (888) 327-4236.
GM's number for this recall is N202305070.
