2007–2010 Mack Chu Recall

On certain trucks, an electrical short circuit in the fog light circuitry could result in a loss of low beam headlamp function. Loss of headlamp illumination, should it occur during a rainy/snowy day, or during hours of darkness, could compromise the driver’s ability to see the road and its users, which could result in a crash causing property damage and/or personal injury. Correction: Dealers will add an extra wiring harness between the cab harness and the Daytime Running Lamp (DRL) module, in order to isolate the fog light circuit.
