Service bulletin 4624

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

142032017-02-02. Service bulletin. 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.
