Real risk of harm even if no illness or injury has been reported yet. Stop using the product and follow the agency's guidance.

Plain-English summary
Navistar, Inc. is recalling certain 2023 and 2024 IC BUS school buses, including the IC RE, IC EV, and IC CE models. The fasteners connecting the transverse torque arm to the rear axle housing may have been tightened incorrectly during manufacturing.
Incorrect fastener tension can allow the rear axle to shift from side to side. This can cause a loss of handling and vehicle control, increasing the risk of a crash. Additionally, a loose rear axle may cause vehicle instability during an emergency evacuation, increasing the risk of injury to occupants.
Approximately 6,948 vehicles are affected by this recall. Owners should contact Navistar customer service at 1-800-448-7825. Owner notification letters were expected to be mailed on February 6, 2023. Dealers will replace and tighten the fasteners at no charge.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153) or visit www.nhtsa.gov for additional information.
