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.
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.
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.
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.nhtsa.gov.
