Diagnostics & Engine Repair
Check Engine Light On? We'll Find the Real Problem.
That dashboard light doesn't have to ruin your day. A lot of shops will scan the code, Google it, and start swapping parts until something works. We don't do that. At University Auto Service, we use professional-grade diagnostic tools to read the codes, then actually test the components to confirm what's wrong. You'll get a clear explanation in plain English, not mechanic jargon, and a written estimate before any work begins.

Randy has been doing great work on my 2008 Lexus for about 4 years now and has always been able to help out when I'm in a pinch. He repaired my rear differential, brake pads and rotors in October 2020 and they have held up well ever since.

These guys are absolutely the best!!! Was on a road trip and my AC stop working (what luck!). I brought it in to their shop, within an hour my AC was fixed at a good price! The owner is super kind and friendly. The other workers are as well.

I cannot even begin to say how fabulous this shop is!! I called them because my truck started misfiring while I was towing my horse to Kentucky. Being far from home with a horse in the trailer I was in full panic mode. Randy was not only calm and helpful, but he helped me trouble shoot where to go..
