Summary
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."
Consequence
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.
Notes
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.

Vehicles covered

As listed by NHTSA. A recall usually covers only some vehicles of each model and year, often a production date range.

Has your International Motors been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A International Motors dealer can also check your VIN. Recall repairs are free.
