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. The chassis harness and the coolant return hose from the radiator to the reservoir (surge hose) may chafe. Continued chafing could cause wear in the harness and/or hose, ultimately causing a hole in the hose with the potential for engine coolant to leak and/or causing damage to the harness with the potential for a short circuit.
Safety risk
Leaking engine coolant and/or a damaged wire harness may result in a no-start condition, an engine stall, or an electrical short. These scenarios increase the risk of a crash or fire.

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.
Safety 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.
