Have not been pleased with this Cadillac. I had never owned a Cadillac and I can truthfully this will be the last one. The transmission is extremely rough shifting at lower speeds - normal says the dealer. When it is cold -has real trouble shifting from reverse into drive -dealer can never duplicate this problem when I take it in. It uses a QT of oil every 1000 miles - no leaks and this is normal per the dealer . The check engine light goes on and off but the dealer can't find out why. Panaramic sunroof makes lots of noise - dealer can't seem to fix that problem either. Throttle body and fuel pump both had to be replaced at 50k.
