Had my local mechanic replace rear brakes. Still getting noise from rear wheels, took it to Buick dealership to investigate. They adjusted brakes and they failed within a week. I was then charged $1000 plus a $400 rental car bill while they "fixed the brakes." After getting my car back it was still "whirring", turns out the problem was a hub bearing failure on all four tires.

(1)loud road noise from right front wheel, wheel bearing failure, dealer repair-very expensive! (2)ac no longer worked - ac condenser failure. Dealer repair also very expensive!! (3) gas gauge quit working, misc electrical problems- at dealer right now probably expensive!!!

My wife had a flat tire and destroyed the tire on the highway. We were sold the tire monitor system with the cxl. It is also circled in our brochure from the salesman. The vehicle does not have the system and GM is blowing us off! this is false advertising. Also, this year, both rear axle hubs have gone bad as well as problems with the rear drive module.
