There are 3 owner-reported electrical system complaints for the 2011 Chevrolet Corvettein NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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 HAS FRACTURED AND SEPARATED. WHEN THIS OCCURS, THE LOW-BAEM HEADLAMPS WILL NOT ILLUMINATE. AS THE UBEC HOUSING COOLS AND CONTRACTS, THE LOW-BEAM HEADLAMP FUNCTION MAY RETURN. THIS CONDITION IS NOT AFFECTING 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 .....WHICH WOULD BE FATAL. APPEARS THAT OTHER YEAR CORVETTES HAVE HAD THIS ISSUE (SEE DEC 2014 BULLETIN 13146 "RECALL BULLETIN" - LOW-BEAM HEADLAMPS INOPERATIVE." GM ADMITS TO A "CUSTOMER SATISFACTION PROGRAM" WHICH IS NOT A "RECALL." AND THAT THEY ARE NOT REQUIRED TO DO ANYTHING ABOUT IT. SWEET! HOW CONVENIENT FOR GM.
