RECALL INFORMATION
(May 2022)
Mack Trucks has determined that certain 2021-2023 model year LRE vehicles could experience an increased torque on the steering wheel due to pressure drop in the power steering system. On affected vehicles there is a potential for the driver to lose hydraulic assist during strong steering/evasive maneuvering which may result in a vehicle crash, property damage and/or personal injury.
Mack Trucks has not received any complaints or reports of vehicle crashes because of this safety issue; therefore, Mack considers this as a proactive measure to protect the public and Mack’s customers from the potential risk associated with this defect.
To ensure that these vehicles meet Mack’s stringent quality requirements, follow the instructions outlined below to replace the steering gear, pitman arm, steering gear return hose, servo pump’s power cable, and to reprogram the electronic control module.
VEHICLES AFFECTED
Certain Mack LR Battery Electric Vehicles manufactured between February 20, 2022, and March 07, 2022.
VEHICLE QUANTITY
There are 37 vehicles affected by this recall. (33 US, 4 CAN)
