I bought a new Cadillac XTS in 2014. It broke down and had to be towed 8 times in 18 months, before I traded it in. I’ve had several new vehicles (23 in total) and put 100-250K on many of them, with no repairs done to them. My current vehicle is a GMC w/ 5.3L and I’ve logged 124K miles on it. Never had any problems whatsoever. My best run was a Toyota Tacoma, which I logged 250K miles on and my wife wanted something newer to drive (She took it over when I thought it was too small for me). I also had an ’00 Chrysler LHS that racked up 200K miles perfectly (the dealer was amazed when I traded it in and they pulled up “no repairs”). Same with a ’95 Mercury Sable. It was rock solid. Overall, the very worst vehicle was a ’95 Hyundai Sonata. Was at the dealer 31 times in 12 months. So, there is a worse car than a Caddy...
