Wiring problems of the 2011 Cadillac CTS

I purchased a new 2011 Cadillac Cts4 in August 2012 from herb chambers Cadillac in lynnfield MA. Since that time, I have driven the car approximately 60,000 miles. This problem affects virtually all (tens of thousands!) Cadillac Cts and srx vehicles built since 2008. After driving the car for a few months, I noticed that condensation appeared in the headlight assemblies after driving in or parking in the rain. The condensation would naturally evaporate during evaporate after the rain stopped. Over time, the low beams became dimmer and dimmer. They have become so dim that driving in other than well-lit areas is dangerous. I contacted the mike anagnos, service manager at herb chambers Cadillac. I presented the problem to him. Without inspecting the car, he stated that this was a common problem and that the headlights and headlight wiring harness needed to be replaced. He stated the replacement of two headlights cost would be $1400. 00. He explained that the problem was caused by water ingress to the headlight assembly causing the headlight connectors to corrode and 'melt'. He offered no further explanation as to why two headlights would cost approximately 10% of the car's bluebook value. I asked him if the corroded wiring that melted presented a fire hazard. He did not reply. I believe that this presents a risk of under-hood fire. If you do an internet search on Cts or srx dim headlights, you will find hundreds of complaints about this problem and the outrageous cost to repair. See also Cadillacforum. Com and justanswers. Com my research indicated that when Cadillac repairs these vehicles, they use the same parts that were used when the car was built. . . Virtually guaranteeing that the problem will present itself again. This car is a danger to drive at night and a fire risk from the 'melted' wiring harness.

My Cts was in a non gm authorized mechanics shop having oil change and brakes done. While working in the car I asked to have them look at my rear assist camera. The camera and wiring to the camera were actually smoldering at this point. My mechanic also told me that the transfer case was leaking and that the central drive shaft was bad. My mechanic removed the smoldering rear assist camera, put the Cts back together and I drove it over to the Cadillac dealership to have the warranty work done on transfer case and drive shaft. My mechanic also replaced the smoldering camera and gave it to me in a bubble wrapped bag along with wire harness. You can see where fire occured on the camera and the smoldering wires. The service manager at crown Cadillac gave me the product allegation phone number which I called and got a file number. I informed gm about the fire/smoldering rear assist camera and was told by asia at the product allegation department that since the removal of the camera was not done by an authorized gm dealer that they would not cover the camera. I asked her if it made sense to leve a product in the car that was on fire and smoldering? this product could have been smoldering for 30 days when the rear assist camera quit working. My concern is this, the camera had been smoldering for some time. The camera was still smoldering and at one point obviously was in flames. I believe we dodged a bullet that the car did not erupt in flames and destroyed our 2000 corvette and f150 plus the house itself as we have an attached garage. The Cts has other intermitten electrical issues such as seat heaters sometime work and sometimes they don't. The car when you turn it off will continue to run. Again intermittently.
