The problem
Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain 2020 Isuzu NPR-HD Gas (Crew Cab) and 2020 Chevrolet 4500 (Crew Cab) trucks equipped with 6.6L gasoline engines. The positive cable connecting the battery to the starter may be too long and may have been routed too close to the right-side exhaust pipe.
The risk
Over time, heat from the exhaust pipe may cause the conduit and insulation to deteriorate, exposing the wires, possibly causing a short circuit which could result in a no-start condition or a fire.
The fix
Isuzu and Chevrolet will notify their respective vehicle owners and dealers of this recall, and specifically of the need to adjust the positive cable in subject vehicles, and owners will be informed that the recall repairs will be done free of charge. The recall began December 11, 2020. For additional information, Isuzu owners may contact Isuzu Customer Relations at 1-866-441-9638 and Chevrolet owners may contact the GM Medium Duty Truck assistance line at 1-800-862-4389. Isuzu's number for this recall is V2005.
