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."

Risk. A vehicle that drifts out of its lane increases the risk of a crash.

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.

Service Brakes, Air › Supply › Reservoir/Tank19V107000

Filed Feb 21, 20199 vehiclesMack Trucks, Inc.

Defect. Mack Trucks Inc. (Mack) is recalling one 2014 Pinnacle (CXU) vehicle and certain 2018-2019 Mack Anthem (AN) vehicles equipped with air brake supply tanks that have an air volume amount ranging from 70% to 96% of the amount required by the regulation. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 121, "Air Brake Systems."

Risk. The undersized air brake supply reservoir may provide an insufficient air supply to properly operate the brakes during repetitive brake applications, reducing braking performance and increasing the risk of a crash.

Remedy. Mack will notify owners and dealers will add an air tank to the affected vehicles, free of charge. The recall began April 10, 2019. Owners may contact Mack customer service at 1-800-866-1177. Mack's number for this recall is SC0417.

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
