Don't buy a Cadillac! Read the forum, how many problems and what a terrible customer support. Buy Toyota or Lexus!
All brands have their dogs. I guess you can buy a Toyota or Lexus if you don't care that you'll be driving some of the ugliest cars with the worst infotainment interfaces around.
And in terms of reliability of the XT5 particularly there's this.
2022 Cadillac XT5 Among Most Reliable Midsize SUVs: Study (gmauthority.com)
Sure I don't love Consumer Reports, but keep in mind they have a history of loving to bash GM. So if they say something from GM is good, the data must be pretty irrefutable.
My two XT5's have been very comfortable, reliable vehicles.
I agree with those who have posted above saying go with 2020 and above. My 2021 is much better with the tweaks that have been made than my 2018 was. No more rattling noises, better CUE software, better infotainment physical controls, start-stop OFF button.
As far as mileage, I'd consider the vehicle as a whole, not just the mileage. I've seen vehicles two years old all highway driven with a ton of mileage but the car is like new. And I've seen others with low mileage but the car looks like it's been through the ringer. I guess my advice would be to look for a CPO XT5 that has some MFG warranty left on it so you have some peace of mind. Good luck!
My car from Wisconsin. And I see traces of winter chemicals on my car. Chrome has traces of corrosion. Му car is 2 years old.
Ummmmm..... The chrome on the outside of the XT5 is chrome plated PLASTIC. That doesn't rust or corrode. Sorry.
I live in Northern Ontario, we know road salt. Trust me, I've had many cars 10 years old claimed by road salt corrosion. But guess what, the chrome plastic bits don't corrode.
Do you get rock chips causing pitting on them, sure. Maybe if it's a bad chrome job it might even peel (never seen that on any of the 8 Cadillacs I've owned over the years). But it doesn't corrode. I have a 65 Mustang with steel bumpers, now that chrome will corrode. But not what's on the outside of an XT5. Doesn't happen.
