Buick has always meant quality, I guess not anymore. We bought it used and they had just put it on the lot from trade in. We test drove it and it was making a very slight noise in the right rear. Said they had rotated tires and cleaned the car, so I thought maybe its just the tires and it will settle in. Nope it just got worse. I have always done auto repairs and engine rebuilds and know my way around a car. I thought there is no way the hub bearing was bad already from my past experience with cars. Never ever scene on go bad before 100,000 miles ever. Was ready to just get tires on it, but decided to take it in to dealer to have it checked out before I put tires on it. They said it was the wheel bearing and under warranty and fixed it. Great all fixed, but WTF does this mean I had to do wheel hub bearings every 30 -40k miles. Completely unacceptable.
