LEFT HEADLIGHT FILLS WITH WATER DURING A RAINSTORM OR CAR WASH. HEADLAMP IS FOGGY WITH MOISTURE REDUCING THE LIGHT OUTPUT AND WILL CAUSE A PREMATURE HEADLAMP FAILURE.

#1 THE ABOVE MENTIONED VEHICLE WAS PURCHASED IN CHICAGO ON DECEMBER 22, 2009. THE ODOMETER READ 29,832 MILES. WHEN THE CAR WAS DRIVEN BACK TO MARYLAND, A MARYLAND VEHICLE INSPECTION WAS REQUIRED. THE HEADLIGHTS FAILED THE INSPECTION. #2 OVER THE PAST TWO YEARS, CONDENSATION BUILT UP INSIDE BOTH THE HEADLIGHTS. IN THE PAST MONTH, I NOTICED THERE WAS ONE INCH OF WATER IN THE DRIVER SIDE HEADLIGHT. THE WATER HAS NOW SHORTED OUT THE LIGHT. I BELIEVE THIS PROBLEM IS A DEFECT AND I HAVE READ SIMILAR COMPLAINTS ON CAR FORUMS ON THE INTERNET. CADILLAC WILL NOT COVER THE COST OF THE REPAIR BECAUSE THE CAR NOW HAS 63,000 MILES. I AM ON A FIXED INCOME AND CANNOT AFFORD THE COST OF THE REPAIR WHICH CADILLAC QUOTED @ $1250.00.
Official recalls
214V542000 · Fuel System, Gasoline:delivery:fuel Pump
Sep 9, 2014
General Motors LLC (GM) is recalling certain model year 2004-2007 Cadillac CTS-V vehicles manufactured October 6, 2003, to March 15, 2007, and 2006-2007 Cadillac STS-V vehicles manufactured June 23, 2005, to March 15, 2007. In the affected vehicles, the electrical terminals of the fuel pump module may overheat resulting in the melting of the flange material.
Consequence & remedy
Consequence: If the flange melts, a hole may be created allowing the fuel pump to leak fuel, causing the vehicle to stall, increasing the risk of a vehicle crash. Additionally, leaking fuel in the presence of an ignition source increases the risk of a fire.
Remedy: GM will notify owners, and dealers will replace the fuel module and fuel tank jumper harness, free of charge. GM sent out interim notices in late October. The recall began on March 12, 2015. Owners may contact Cadillac customer service at 1-800-458-8006. GM's number for this recall is 14405.
