This shop is totally legit and comes equipped with knowledgeable, competent, and skilled diesel mechanics. John, the owner, oversees all operations and gets dirty himself. Jordan, his son, is his right-hand man and is involved in all aspects of the business. This place is crazy busy but John scheduled us in the same week we called. The work was performed quickly and competently. The price was not cheap but fair. For years, our CAT C7 was having recurring overheating issues. Up till now, shops have cleaned the radiator as a fix. Finally, a shop who properly diagnosed the real issue and solved the problem. We've gone 1,000 miles up and over significant grades while barely breaking a sweat. Amazing and wonderful. THANK YOU JOHN, JORDAN, and Staff!!!

Once again, this shop saved my bacon. Entire fuel lift pump system needed to be replaced, They quoted me a decent price and came in under budget. Thank you once again! Great people with great customer service skills.

Driving through AZ, I had to pull off the highway due to my steering shaking. I found Ascendant Auto, and although they didn't have time to work on my van, Jordan came out and did a cursory examination and took time to look up some information. He stated they could to the repairs, but the local Ram Dealership could probably get to it sooner. I was extremely appreciative of Jordan taking a few minutes to help me out. Great customer service!!!

Can't express the gratitude for the effort that John and his team put in to repairing our F450. It was a challenge that I'm sure would have cost me more hours and parts elsewhere. Highly recommend their shop and we will return here for all our maintenance work. Thanks again.

Very good service by professional staff. Took our motorhome to them to get a new turbo installed. It turned out to be a nasty job, but being the professionals that they are, they got the job done and I thank them very much. I highly recommend them. It is great to find people that know what they are doing and can get the job done right

My grand daughter s truck broke down late on a Saturday night with a horse trailer attached. I live 90 minutes north so I had it towed to ascendant and left it in the parking lot. I had never used them before but I didn t know what to do. I called them Monday morning. Everyone was so helpful. Even tho they are appointments only they worked on my truck and had it finished by Tuesday afternoon and the best part it was super reasonable. Jordan was professional and fast. I would recommend this location to anyone with a diesel truck!

I had them replace injectors in my Duramax. Did an awesome job. Not like a lot of the other Diesel repair shops that charge you and arm and a leg. Nice to still have a Friendly family run business. They will be doing all my repairs in future and highly recommend!!!

Blew my left rear air bag on my first trip in my brand new motorhome. John and his tech were awesome. John got the part sent to him overnight and the tech easily installed it. He made sure there was no other damage and stayed while testing the new bag to make adjustments. Great service. Honest, reliable, and fair businessman are hard to find these days John and his team are all that.Thans again John

I am grateful to have found these guys. Good mechanics, family run and no monkey business. Needed our RV diesel engine serviced and they know their stuff. My only complaint, minor frustration from lack of communication between the office staff. I think they may have more business than their software program can manage. My requests were not always passed on to the mechanics. Had to repeat my requests to multiple employees.Over all, I have lots of faith in the mechanics here and would use them again.

This is the place to go!! John was honest and upfront and didn't make any promises he didn't keep! Took my kenworth T660 in for major transmission & clutch repair & John Jordan and the rest of the folks were amazing! Nice modern clean facility with a very nice waiting lounge. They even fixed a couple"small things" and now my old work horse is running smoother and better than ever! Definitely the place you want to go for any repairs, minor to major. Thank you John Jordan & the crew!! This owner operator and his family are extremely grateful.

Jordan Moreno is a good dude, great mechanic and trustworthy!! He did a bunch of work on my 2011 Dodge dually. Everything was quoted ahead of time, the price was more than fair didn t change when I picked up my truck. I highly recommend this shop for all of your mechanical needs. It s hard to find a trustworthy shop that does quality work at a fair price. Give these these guys a chance!! There here to stay and it shows!!Thanks again Jordan for a job well done!!Joseph McCarter

The absolute best Diesel shop around anywhere. My husband took my truck in and it needed the exhaust manifold done. These guys got it done with no issues faster than expected. Thank you guys for great work in a timely manner! Got my truck back and it s perfect with even better mpg than when I took it in!

Fast, Efficient, Fair!My Freightliner's water pump failed on a Friday afternoon. John was able to get me in and back on the road by Saturday afternoon. I also had him PM Service the truck and trailer while it was in his shop. What's more, final bill was over $500 less than what I'd expected. Thank you John for a great job at a more than fair price! I'll definitely be back!

If you need your truck or trailer fixed this is the place you want to go to. John is really helpful and knowledgeable, not only did he fix our truck in the time promised and at a reasonable price. But also helped us find a tow truck and a truck to delivery a load for us as we weren t going to make the delivery because to the truck issue. Really nice guy to work with. Thanks a lot John we really appreciated it, I wish ther would be more mechanics (people) like you. Thanks again

I had a good experience taking my motor home for some engine a/c work. John was very professional and kept me informed as to the repair progress. I was very satisfied, pricing and shop charges seemed very fair and reasonable. I will go back when I need work done in the future.

Outstanding is all I can say about this shop and the crew. John helped us out with an issue with our diesel roadside less than an hour after making a call. He brought parts and fixed it right on the spot! Definately need more shops like this around. Thanks Ascendant and John!

I had a fuel problem with my diesel motor coach. Stopped and spoke with John and I was given an appointment to get the coach in the next day. I received very efficient and professional service. A part was ordered and my coach was fixed on the day the part arrived. The service I received fixed my problem. I can't thank John and his service tech enough. It was a great experience and I would recommend Ascendant Auto & Diesel to anyone needing diesel service.

John and the guys over at Ascendant Auto & Diesel will forever have my business. John was very informative and knowledgeable about the several issues I was having on my tow truck. The turn around time was absolutely amazing. My downtime was minimal a d being a small business that's key. Thanks guys and I'll be returning for all my needs.

I called in for emergency roadside assistance at 1600, at first they answered and made it clear that they were busy which is understandable since I had been calling for service and was unable to get an answer from TA or Speedco. They got all the info needed and gave me an ETA of 90 minutes.Two hours went by and they called me to ask if I still needed service to wich I said yes... they never arrived. I had to call a different service truck the next day.

I just want to say thank you to John at the Ascendant auto n diesel shop in Casa Grande Az for getting my dads truck back on the rd in a few min., my dads truck broke down on the freeway and while most shops were closed today Saturday he answered the phone and was willing to help them out and look into the issue even though he was busy with other jobs. I will most definitely bring my vehicles to his shop for all future mechanical needs. Thank you very much John!

Awesome diesel mechanics! I have a Ford 6.0 diesel and I won't take my rig anywhere else. Family owned business with top notch experienced mechanics that work on anything from semi trucks to pickup trucks, plus a little flavor working on cars.

The only place to go! Honest, hardworking Christian Father and Son Combo. Reasonable prices, quick service. They used to work at a dealership, but then started their own shop. If your a trucker passing through with truck problems this is THE shop, if your a local trucker ; you already know this:)

These folks were incredibly accommodating, and took our call two minutes before closing on a Thursday evening when we broke down pulling into Casa Grande. Not only did they take the call, they let us stay in the lot for the evening in the comfort of our Coach. Our family was up and out of the coach around 8am and John called, having fixed the issue by 11am. We are so greatful, and their attitudes toward our emergency made everything feel so calm! Thanks Ascendant!
