I rented this vehicle for 12 days in San Diego over the holidays. In spite of reading the manual twice and calling Onstar (they were no help), I could not figure out even the most basic commands like getting the seat memories to stick or getting the trip meter to appear on the display. Even more infuriating: most of the time when exiting the car, the driver's seat would move back and the outside mirrors would point towards the ground. While I appreciate the car's attempt to ease egress and spot puddles, the problem is the seat and mirrors would not return to their previous position when getting back in the car! It's really aggravating having to reset these items every time you go somewhere. My opinion is CUE is a disaster. It was easy pairing my phone, however. Additionally, the XTS now has rubberband 19 tires that ride like crap! I could feel every little imperfection on San Diego's crappy side streets. On the plus side, the car's handling was quite good. The XTS is a blast to throw around corners, although I miss the sound of a V8 and the car could definitely use 50 more lbs. feet of torque. Overall, I dropped this car off thinking Cadillac doesn't know what the cars mission is and who their customers are. I do know I could never spend $55K on a car who's controls can't be figured out, with a ride that my Ram 1500 puts to shame!
