I bought this vehicle recently, and was a certified used vehicle. I had it less than 90 days when my compressor caused my car to break down. After a diagnosis by a certified Cadillac dealer, they told me that the compressor fell off, and one of the bolts broke off in the engine block. The other two bolts were nowhere to be found. The dealership where I bought this vehicle will not take responsibility of this issue. My extended warrant provider will replace the compressor, but will not pay for the labor that is required for the extraction of the compressor bolt. I'm confused!!! They claim that the bolt is not covered!!! SMH
