I have had nothing but trouble with my 2006 Cadillac STS V8 since I took delivery of it. First, the delivery was delayed at the dealership because the entire radio had to be replaced. After the first 1,000 miles, a loud noise like crunching tin cans developed in the front-end. The dealership has attempted to fix it several times without success. I have been waiting on another part for over a week which they hope will remedy the problem. Meanwhile a coil in the engine went out causing it to operate on less than all 8 cylinders. I have communicated with Cadillac customer relations but have gotten absolutly no relief. Buyers beware.
When operating properly the vehicle is fun to drive.
The quality control on this car is awful. Cadillac needs to inspect all of the parts and aspects of the vehicles before they leave the factory. All of the problems I have experienced should have been noted before the car left Cadillac's possession.
