The problem

Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain 2017-2019 N-GAS HD and Chevrolet Low Cab Forward 3500 and 4500 vehicles and 2018-2019 Isuzu FTR and Chevrolet Low Cab Forward 6500XD vehicles. The power supply bolt in the relay box may not have been properly tightened during harness production at the supplier. This may lead to melting of the power wire and/or a loss of electrical power to the vehicle, which can lead to a stall.

The risk

A stall can increase the risk of a crash.

Isuzu will notify owners, and dealers will inspect the relay box power supply bolt, tightening it as necessary. If the harness or relay box is found to be damaged, it will be replaced or repaired, free of charge. The recall began October 24, 2019. Owners may contact Isuzu customer service at 1-866-441-9638.
