I went to Mr Lube for an oil change for my girfriend's car. During the oil change they recommended that my serpentine belt be replaced. I looked at the belt myself and found no cracking or anything so I turned down the belt replacement. The next day my girlfriend tried to start the car and it wouldn't turn over. She had it towed to a garage and the mechanic told her that the battery terminal was broken inside the battery (how this could be done during a routine check I don't know). He also checked the belt and said it was fine. I called Mr Lube to complain and they said if I didn't like their service then I shouldn't come back, and then hung up on me. Since then I have been to Jiffy Lube three times and they haven't yet recommended replacing the serpentine belt. This was the Main St Vancouver location of Mr. Lube and they suck.
