What this means for you

Illness, injury, or structural failure has been reported. Stop using the product immediately and contact the manufacturer for a refund or repair.

Our severity reasoning: The source text explicitly states that the defect increases the risk of a crash or fire, which aligns with the rubric criterion for 'significant injury/property-damage reports' or structural/electrical defects posing severe risk.

Plain-English summary

Isuzu Technical Center of America, Inc. is recalling certain 2020 Isuzu NPR-HD (Crew Cab) and Chevrolet 4500 (Crew Cab) vehicles equipped with 6.6L gasoline engines. The recall involves 46 vehicles in total. The defect involves the chassis harness and the coolant return hose from the radiator to the reservoir, which may chafe. Continued chafing could cause wear in the harness and/or hose, potentially leading to a hole in the hose with engine coolant leaks or damage to the harness causing a short circuit.

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 and Chevrolet will notify their respective vehicle owners and dealers of this recall. The recall began on December 11, 2020.

Owners will be informed that the recall repairs will be done free of charge. The corrective action involves adjusting the positive cable in subject vehicles.
