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.

My cadillac sts left front light seal leaks water into it and now the headlight won't come on. This was notice upon purchasing the vehicle and was told it was a manufactures problem. Now my head lamp only works on brights.

The headlights have a major fogging issue which leads to impaired visibility both for the driver of the car and for other drivers on the road. This issue is being reported in sts and cts cadillac forums at least as far back as 2008. I believe this is a defect in either the design or manufacturing of these components.

My wife went to the local gas station and as she was pulling in she made a right hand turn past the pumps to park. She hit the brakes and the car sped up. She slammed them harder and it slightly slowed down but she hit 2 guard rails and then crashed into the cinderblock wall destroying the front bumper, both front fenders, headlights and the internal aluminum bumper was crushed as it was designed to do. The air bags did not go off but she was not hurt. She said the car sped up while the brakes were deployed. Also, after she hit the wall she tried to put the card in reverse but she had to put it in neutral to actually go in reverse. The car is at the mechanic being fixed at this time but I am concerned about this speeding up instead of stopping when the brakes are applied... This is not a good thing and the insurance company said it was up to me to find the cause. Someone from cadillac or the federal safety agency needs to come and look at this before the car is fixed.

#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.
