One day going to work experienced flood of antifreeze inside of cabin floor, smells was awful. Went to dealer where car was purchased and warranty was expired 3,000 miles ago and had to pay out out of pocket. Car only had 50,000 miles and driven by my wife. It was the heater core they said. Never heard of such a thing at 50,000 miles on a Cadillac. Will never buy another or will recommend and will tell buyers to beware.
