ELECTRONIC STABILITY CONTROL (ESC):CONTROL MODULE:SOFTWARE
- The defect
- Mack Trucks, Inc. (Mack) is recalling certain 2018-2022 Anthem (AN), Granite (GR/GU), and Pinnacle (CHU/CXU/PI) vehicles equipped with "camelback" rear suspension and electronic stability control. The vehicles may not stay in their lane at certain speeds. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 136, "Electronic Stability Control Systems on Heavy Vehicles."
- What it can cause
- A vehicle that drifts out of its lane increases the risk of a crash.
- What the dealer does
- Mack will notify owners, and dealers will reprogram the vehicle control units, free of charge. The recall began on April 21, 2021. Owners may contact Mack customer service at 1-800-866-1177. Mack's number for this recall is SC0423.
- NHTSA's note
- 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.
The repair is free, whatever the age or mileage of the vehicle, and whether or not you are the original owner.
Which vehicles
A recall reaches a range of VINs inside these model years, not every car built in them. Yours may not be covered even if it is listed here, and the only way to find out is NHTSA's own VIN lookup .

Check your own car
A VIN check is the only answer for a specific vehicle, and it also shows every other open recall on it, which is usually the reason it is worth doing rather than reading one campaign.
