Power Train, electrical System
07/01/2026
I purchased the car on XXX. The car has been returned to the service department within the first 3 days. Sold to me without getting fully inspected. Service department did put new brakes and rotors on and I was told (no paperwork given to me) an oil change was done. On XXX in traffic on a dangerous highway, the car cut off. The car was not able to be jumped with AAA, was towed to [XXX]/GMC Service department. I was told by the Asst Svc Manager, on XXX the Tech told him My car was the starter. The part would have to be ordered and would not be ready to the following week. On July 7th I received a call from the SVC Mgr that the engine blew. I had to pull teeth to get the Mgr to pay for the engine of $8500 and yet he wants me to pay $1500.00. With having a car less than 21 days regardless if I went over the 3k miles and as -is, there was a 90 day warranty when everything should be covered. He has now rescinded because I reported this to BBB, Atty Gen office, NHTSA. This car was never i...

Air Bags
07/01/2026
My passenger side, dashboard bowls up in the heat and doesn’t seat properly. My fear for safety is that if I’m in an accident that airbag will not come out due to the dash bubbling because of the defect.. It seems to be an only problem with the platinum editions of the Cadillac XT5’s. There’s no warning lamps and it has not been inspected.

Steering, engine

I had P0128 Code with a warning message " Steering assist is reduced, drive with care". My local mechanic told I need a new thermostat. I have replaced my thermostat and it cost me 700 dollars out of pocket.

Seat Belts
04/15/2026
2017 cadillac XT5 Platinum. Seatbelt CHIME does not activate if the seatbelt is off while driving. Dealer says it is working as it is supposed to in this model year.!!!! Please note that at the dealer we test drove for 3/4 of a mile, and the CHIME went off only after driving 4 blocks and making a right hand turn. It went off again seconds later and 1/2 mile later as we entered the parking lot, as we hit a bump into the parking lot, the chime went off again. My point is that the CHIME should go off at the beginning of the drive to remind the driver that the belt is off, not at the end of a 3/4 mile drive. Their answer is that they tested the seatbelt and no codes were detected. Since the CHIME did go off sometime during the drive, then there is no problem!!!! They CLAIM they tested another 2017 XT5 and it was the same!!! It worked for 8 years, but in the last 2 months, it started to fail with on the driver side. The passenger side later also started to fail, sometimes...

I had to replace the thermostat which is a well known, documented defect/issue for this vehicle/Cadillac. I would like reimbursement from Cadillac.
