What is wrong
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.
What can happen
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.

A recall means the maker found a safety problem and offers a free fix; it does not mean every unit has the problem. Units affected are as reported by the company. Popular models sell more and so have more recalls and complaints. Official public data; texts are shortened. A dealer can tell whether a single vehicle still needs the repair.
