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."
The risk
A vehicle that drifts out of its lane increases the risk of a crash.
The remedy
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.
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.
A safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
