2008 - 2013 Corvette: Customer Satisfaction Program: Number 14203, Low-Beam Headlamps Inoperative

2008-13 Chevrolet Corvette – Customer Satisfaction Program

Number 14203, Low-Beam Headlamps Inoperative

On certain 2008-2013 model year Chevrolet Corvette 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.

All involved vehicles are identified by Vehicle Identification Number on the Investigate Vehicle History screen in GM Global Warranty Management system. Dealership service personnel should always check this site to confirm vehicle involvement prior to beginning any required inspections and/or repairs. It is important to routinely use this tool to verify eligibility because not all similar vehicles may be involved regardless of description or option content.
