First stopped in to have a battery replaced under warranty. They were quick, polite, and got us out in time to get to work without being late.

However, when my wife went back alone to get an oil change she was told she needed a serpentine belt replaced as hers was "showing a lot of cracking and going to fail." They provided her an estimate for over $150; $23 for the belt, $60 to install the belt, and an additional fuel system clean for &79.99. Problem 1: her vehicle does not have a serpentine belt, it has 3 desperate belts to run the AC, Alternator, & Power Steering pump. Problem 2: none of the belts are showing any cracking.

Seems to me that the person she dealt with either got her vehicle confused with another one or was just trying to sell her some work that wasn't needed hoping that she'd agree because she didn't know better.

3 stars because the first interaction with the battery was very good (4 or 5 stars) but the second for the oil change was very bad (1 star)
Output:
3 stars
