Wiring Problems of 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.

On may 18th, 2018 I purchased a 2004 Cadillac Cts from top notch auto. The gas gauge, brakes, a/c, blinkers dash buttons all were not working. He said to bring it the next day and they would fix it all. I ran out of gas getting there the next day due to not having a working gas gauge. I spent the entire day there and they did nothing to fix the car. The next day the computer (ecm) went out on the car and the engine light came on saying the catalytic converter was bad. I took the car back and asked for my money back and they said no but would fix it and they had the car for over two weeks. They said everything was fixed but I noticed the car went from 176000 miles to 101000 miles (odometer rolled back). I asked about this and he said it was legal and necessary to fix the car. The day after getting it back the service engine light came on again and the car would not go over 20mph on the road. The codes read po121, po23 and this time it was the throttle body and wiring that were bad. The dealer would not pay for it. I paid $498 out of pocket and another 3 days without the car. I told him the brakes were still bad and the car barely stops and pulls hard to the right. On Friday June 22nd they told me to come in to get the cars VIN checked out for my registration and so they can look at the brakes. They said they brakes are fine (they are not) and he took my keys and would not return them until I signed documentation saying I would not complain or take him to court. It is now July 9th, 2018 and they will not give me my plates or registration and say I am stuck paying for this death trap of a car.

The problem started with the timing chain, which led to coil issues and catalytic converters issues which led to low head beams constantly burning out. Everytime work is done it causes a chain reaction to other parts in the car that requires more and more money. Now the engine light is still on and I am told that since the first catalytic converter was repaired, the second one now needs replacing and the low head beam on the passenger side has wiring issues that will not allow the new bulb to burn, I am told that the wiring appears to be spliced. The catalytic converter was replaced in April and so was the low beam bulb. Headlight was replaced in April, 2015 it is not working today and was told by dealership that the wiring had been spliced or burned out. Radio speakers do not work and all was centered around issues with coils and catalytic coverters.

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.

I was driving in a parking garage so my speed was about 5-10mph when the whole system shut down. The car stopped moving and all of the system warnings popped off (abs, stabiltrack,engine). The car would not turn back on. I had it towed to the shop where I was told that it was an electrical problem. The pcm was replaced and I was told that the problem was fixed. Cost was approx $200. After the original system shut down, I was driving on an exit ramp to the interstate when once again the whole system shut down. All of the system warnings popped up and the car would not turn back on. The car was towed once again to the dealership where I was told that it wasn't the pcm and that they would have to charge me $265. 00 to investigate the problem. The problem was said to be the electrical wiring on the drivers side from the front of the car to the back of the car. It was fixed for approx $800. 00. Each of the system shut downs happened within 6 months of each other while operating the vehicle. This is very dangerous and makes me feel very unsafe about operating the vehicle. This needs to be investigated for the safety of drivers.

There have been multiple electrical problems with the Cts starting with wiring melt down in the front end. Recently, both the driver side and passenger side door latch assembly's went bad resulting in situations where the doors could not be opened from the outside or inside. If there had been an accident, the doors would not have opened and the driver or passenger would not have been able to open them from the inside.

Passanger side sunvisor wiring caught on fire and burnt some of ceiling upholstery and melted plastic trim around sun roof .
