The defect
Navistar, Inc. (Navistar) is recalling certain 2023 IC RE, IC EV, and 2023-2024 IC CE school buses. The fasteners that connect the transverse torque arm to the rear axle housing may have been tightened incorrectly, which can allow the rear axle to shift side to side.
The risk
A rear axle that moves side to side can cause a loss of handling and control, increasing the risk of a crash. In addition, a loose rear axle may cause vehicle instability during an evacuation in an emergency, increasing the risk of injury.
The remedy
Dealers will replace and tighten the fasteners, free of charge. Owner notification letters are expected to be mailed February 6, 2023. Owners may contact Navistar's customer service at 1-800-448-7825. Navistar's number for this recall is 22527.
