The guys in the shop did a diagnostic on the system, called same day an said what was going on, they had the parts in stock and was able to fix same day and return my Acadia to me.

"Jose at the front counter provided the best customer service and was absolutely very cordial and professional. The interaction I had with the techs was also very genial. I was given a checklist of issues that I was already aware of and I will definitely return to O.C. Automotive and Diagnostics to remedy these minor concerns."

"Anthony and his team are the best! I mainly communicated with Jose who was so helpful, kind, and communicative. When my car’s diagnostic was ready, Anthony took the time to explain the results and walk me through my options and his recommendations. I so appreciate the time and effort from the whole team. I’ve been coming here for years and cannot recommend them enough!"

"Amazing customer service from the start to the finish. For years I was having an electrical problem with my RV. I took it to O.C. Automotive Diagnostics and they replaced the battery and the alternator. 2-weeks later, My coach would not start and it was parked at my house. I called Gabriel and he was able to send Anthony and one of his mechanics to my house to check out the problem. with in 1/2 an hour, they found the problem and fixed it. Amazing communication and customer service. I highly recommend them!"
