The vehicle has experienced repeated fuel system failures. The fuel pump control module (FPCM) is a known General Motors issue on similar vehicles, but this specific vehicle was not included in a recall. The vehicle now displays diagnostic trouble code P2635 – Fuel Pump Flow Performance. The engine hesitates and loses power during acceleration, especially under load or when the vehicle is warm. Prior to this code, the vehicle repeatedly reported fuel injector-related faults. Four fuel injectors have already failed and required replacement, causing significant financial loss. Based on diagnosis, the injector failures appear to be secondary damage caused by improper fuel control from the fuel pump control module. This condition creates a potential safety risk due to unexpected hesitation and reduced engine power while driving. The issue appears to be related to a systemic electronic fuel control problem rather than normal wear.

I bought cadillac XT6 four months ago . Last week i noticed that car steering lock when turning right on highway over 25mph. I went to the empire cadillac of long island city (NY). Mechanic took test drive with me and even he noticed that there is some problem. After keeping my car 2 days they said they did not find anything. I ask them to change the steering motor but mechanic said they know better than me. I picked up my car and same problem is there. Locking steering on highway is very dangerous. Please help
My lift gate would open by itself when I put the car in park. It would also open overnight while parked in the garage. When I discovered it open, the battery had ran down. Opening while in park happened about 6 times.
I purchased a 2023 Cadillac XT6 .the issue is when I SHIFT into reverse at night the back up camera get very dim and it is very hard to see anything thru the rear display. Cadillac say's it is working as designed. .They are correct. I tried this on other Cadillac XT6 car and same issue. There is a safety issue it is VERY dim. I tried a Buick,, and Chevy and they both worked great I could see at night in a dim Garage .All ALL they say is "it is working as designed". This answer does not fix a safety issue that is required to work in ALL cars. It is very hard to see what is behind me. The dealer has seen it and admits there is a design issue. However they can only tell Cadillac that "it is working as designed
I have a Cadillac 2023 XT6 When I put the car in reverse in the daytime the Back up camera display works fine. If it is at night,Raining, or during any hours of the day like in a garage the display dims .It is hard to see a person behind you or any poles. When shifting into Reverse, it is bright then it goes dim. I brought it in to the dealer and they gave me a Chevy loaner and that works great and my last car worked great. The dealer checked everything, Ans I was told "it is working to spec" although they see an issue that they can't fix.
During a drive at about 40 MPH down a straight, dry two-lane, something went wrong and it decided to encourage me to drive into the ditch, steering me directly off the road. It was consistent, and when I found a stretch with a wide shoulder to see what would happen, it took me unerringly to the right, onto the dirt. For me, it was unnerving and distracting, but I could only imagine what would have happened to an elderly driver with a loose grip on the wheel.
