Navistar, Inc. (Navistar) is recalling certain 2021 International LT vehicles equipped with a Cummins X15 engine. The capscrews that attach the flywheel to the crankshaft may have been improperly torqued, allowing the flywheel to detach.
A detached flywheel can cause loss of drive power, increasing the risk of a crash. Additionally, driveline pieces may be ejected from the engine compartment, increasing the risk of injury.
Navistar will work with the engine manufacturer Cummins Inc. to notify owners, and Cummins dealers will properly tighten the capscrews and inspect for possible damage, repairing any damage found, free of charge. The recall began on March 29, 2021. Owners may contact Navistar customer service at 1-800-448-7825.
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.safercar.gov.
