Cummins Inc. (Cummins) is recalling certain PowerDrive EV drivetrains, part numbers 4000EV, 6000EV, and 7000EV sold for installation in school buses, step vans and medium-duty trucks. A connector within the wire harnesses may become unplugged and cause loss of communication between control modules, resulting in sudden loss of drive power and power steering.
A sudden loss of drive power and loss of power steering increases the risk of a crash.
Cummins will notify the vehicle manufacturers that purchased the units, and Cummins will install a cable tie on the connector to maintain the connector locking tab in the locked position, free of charge. The recall began March 12, 2020. Owners may contact Cummins customer service at 1-800-286-6467.
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.
