We bought a 2018 Buick Regal TourX two months ago. It had 16,000 miles on it. Nice car, kinda like a station wagon. All wheel drive. Anyways, after a recent snow storm, the car started shaking at 50+ MPH. Probably snow and ice in the wheels. So I went to the carwash twice and did a good cleaning job. Still shook. The dealer let us keep the car in their heated garage overnight to melt the ice. Next day, it still shook over 45 MPH. The dealer kept the car and told my wife yesterday that they were replacing two tires that were "out of spec and couldn't be balanced." OK, great. But, what would make two tires go "out of spec" and need to be replaced? The tires were covered this time but they won't be the next time it happens (if it does).
I have the feeling the dealer isn't telling us the whole story.
Alignment problems, suspension problems? Any ideas?
It's a Certified Pre-owned with a lot of the factory warranty left on it.
