I'm beyond frustrated. Purchased 2020 XT4 less than two months ago. This vehicle is supposed to have been a returned lease and is CERTIFIED PRE-OWNED (supposed to come with extra inspections to assure quality assurance). I noticed squealing from the brakes and asked the dealer to look at is within a few weeks of driving the vehicle. After receiving no call later that day telling me the vehicle is ready, I call the dealer the next day only to be told that the vehicle has an oil leak from cam shaft carrier (in addition to the brake issue that had a previous bulletin regarding it). My vehicle sat a the dealership for weeks. When I finally reached someone for a status update, I'm told they are awaiting difficult to obtain parts. When I finally receive my car after approximately three weeks, when they pull it up into the bay I think "it sounds loud". But I thought...."well maybe it's just the air conditioner". After driving it a few days, I now see it is not the air conditioner, the vehicle is now LOUD! It sounds like a 1995 Oldsmobile or something. I'm extremely frustrated. My trade in which was a 1995 vehicle was in better shape than this one it seems. This is NOT the car buying experience you want. All the thrill of purchasing a new car is gone! First Cadillac and my stomach is turned already.
