The defect
Isuzu Technical Center of America, Inc. (Isuzu) is recalling certain 2018-2020 FTR and Chevrolet 6500XD vehicles. The chassis wire harness outside the relay box may have been improperly routed, potentially allowing the harness to contact the suspension's leaf spring hanger bracket, allowing the harness to get chafed.
The risk
Depending on which wires get damaged, the vehicle can experience stalling and/or reduced functionality of the ABS, increasing the risk of a crash.
