Makes We Service

Awesome help, got me in asap and worked with my schedule. Will definitely be back to use these guys again. Very informative and explained exactly what I needed to hear.

I’m from Massachusetts and I was looking at a truck for sale at a dealership in Tuscon Arizona. It was a 6.0 diesel which I saw based on other reviews that this place specializes in. I called and spoke to a Josh Brown about possibly going over and doing an inspection of the truck for me. He did and he followed me up with a very detailed report about the good and the bad with the truck. I’m very happy I had a trusted set of eyes more than halfway across the country from me to tell me all the

Great people to work with especially Josh! Thank you

Great service great prices very honest. Highly recommended. From now on this is my diesel repair place to go.

Great Experience. You’re not just a faceless number waiting in line at this shop. Very friendly and willing to advise you on your different options regarding price vs time vs quality of parts. I flew in to purchase a used Diesel Pusher with a 1999 8.3 Cummins. They got it ready to go and even found the cracked exhaust manifold and replaced it. They never complained about my coach taking up space in the yard or anything. Nice to find a small town like shop in Tucson.

I was having a hard time finding mechanics in town that could work on my 84 ford E350 motorhome, Jake and his team know what they are doing, and we’re able to help me out no problem, prices are very fair for the exceptional work they did. Would recommend them to friend and family for future work.

The guys here at Tucson Auto Diesel were really nice they took us in immediately explained everything very well. I would definitely recommend any diesel owner to go to them !!!

Excellent service. Honest (which is rare nowadays) straightforward diagnostic, and very professional!! I Highly recommend

This business is a 5+. Josh and Jake went above and beyond fixing my 38 ft diesel pusher motorhome. The service they provided was outstanding. 24 hrs it took them to finish the engine problem. Thanks Jake and Josh for all your help ☺️

Josh and his crew are awsome and the communication he gave me on the progress of the work was excellent I had a diesel van that was leaking oil really bad. No one else could fix it and these guys were able to identify the problem and get it fix. I appreciate all the hard work u guys did, I know how difficult these diesel vans are to work on. And I very much appreciate the excellent service and follow up you gave me. I highly recommend josh and his crew and will be bringing them all my w

If you’re looking for an honest to goodness shop without the highly inflated prices other shops charge. Josh is the guy to see! Josh got my Jaguar up and running. Replaced the MAP sensor and fixed the coolant leak. Josh did an awesome job.

I recomend you make this place your one stop shop, weather you need work done on your automobile, truck, commercial vehicle or your motorhome, they do it all.

We have a Nissan Titan XD diesel that had a specific code show up with engine hesitation. We took it to the local Nissan dealer (having to schedule online because they don’t answer the phones and don’t return calls) and were given an estimate for repairs that was over $2k. We had them clear the codes because that seemed unreasonable. When the truck started to act up again, we brought it here based on Internet reviews. The same codes came up but Josh determined that they indicated turbo issues, N

Visiting from Wisconsin and my RV was losing coolant. Josh spent a considerable amount of time trouble shooting my rig. He did a block test, filled my rig with oil and coolant and helped me on my way. Talking with him through my issue I could tell this man knows his diesels, intelligent, experienced and conservative, Josh has all the qualities of the best mechanics. When we were finished he refused to take any money from me because he said he didn’t do anything, of course he was completely wrong
