Summary

14203 - customer satisfaction program. On certain vehicles, when the engine is warm, the underhood bussed electrical center (ubec) housing will expand, causing the headlamp low-beam relay control circuit routed wire to bend slightly. After the wire is repeatedly bent, it can fracture and separate. When this occurs, the low-beam headlamps will not illuminate. As the ubec housing cools and contracts, the low-beam headlamp function may return. This condition does not affect the high-beam headlamps, marker lamps, turn signals, daytime running lamps or fog lamps. Loss of low beam headlamps when they are required could reduce the driver’s visibility, increasing the risk of a crash. Dealers are to install a jumper wire.

Owners of these vehicles have filed 61 complaints in the lights category.
