Issue: On certain trucks, the chassis and cab wiring harnesses may not have been routed properly.

Note: This recall replaces Transport Canada recall no. 2026-158. Trucks that were repaired under that recall also require this repair. Safety Risk: A short circuit can create the risk of a fire. A loss of power to the wheels and the other issues could increase the risk of a crash. Corrective Actions: Isuzu will notify owners by mail and advise you to take your truck to a dealership to inspect and, if necessary, repair or replace the wiring harnesses. The dealer will also ensure that the wiring harnesses are secured properly.

Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain 2020 NPR-HD (Crew Cab) and Chevrolet 4500 (Crew Cab) vehicles equipped with 6.6L gasoline engines.
