I brought my car in here for a transmission issue, and I had them do a couple of test drives with the car on separate occasions. The final verdict from their team of crackerjack experts: I needed a new transmission for $2300.
This I found very hard to believe, since the transmission only had about 15,000 (of mostly highway) miles on it. So I took the car somewhere else, and a quick and simple test revealed that all I needed was a new sensor. Problem solved, and the car is still running with the same transmission 159,000 miles later.
Needless to say, I have not been back to this location since. I know people can make diagnostic mistakes, but this was a rather glaring one, and involved multiple people.
