Key Fobs weren't working even after changing their batteries plus my Tire Pressure Gauge sensor wasn't functioning. The problem would come and go. OAC diagnosed the problem in a couple hours (my car battery was defective apparently and almost dead and the sensor thing needed re-calibration from a certain device) and completed the fixes needed in a couple more. They were even able to download outstanding software updates for my car's body and engine systems. The service was fast, the people were professional and knowledgeable, and it was an all around great experience. I will definitely be going back the next time I need a car problem fixed.
