I think I got a bad one
 I loved the car when I first got it on 1/31/2012. It did perfect at first, did the "clunk" at 25 - 30 mph and was told it was normal for the car.But it wasnt long before I started to notice little things and some big that were going wrong and I babied this car.About 5 months into ownership the window regulator failed and had to be replaced. A month or so later I started to notice a lot of clunking when I would back up, not cv joint type noise, but more like a series of little clunks. The driver side door and hood seemed to be poorly aligned as the door scraped the paint off the running board and the hood had a major gap on one side. The last straw was the failure of the A/C. I traded it.
