151000 680 Brakes felt weaker and started screeching. New rotors and pads installed. Window regulator went out, the window would roll all the way down, but roll only halfway up. It was the driver's window regulator. 
175000 150 Air was not blowing cold since summer of 2011. Decided to get it fixed. Not sure if there is a slow leak or not. The service rep said that there was no noticeable leak, but they did put in some dye just in case.
