Kristi Diesel Services 3106 South 2750 East, St. George, UT 84790

"Left my truck worst than I brought it in started to over rev before it gave out on me I mentioned the issue they said it was normal as the engine was cleaning itself. Spent over a month in the shop and after a couple weeks I went in to check only to find out no work was done on it that is when I started to rush them after about over a month i got it back and I believe it was left bad intentionally since I rushed them as another defect diesel was burning up twice as fast by they re assured me it was fine I should’ve trusted my gut and gotten a second opinion . When it broke down I brought it in and they only bothered to turn it on and give a diagnosis without looking into the engine they quoted me over 15k for a new engine for a cylinder which they’re not sure if that’s the main issue . Terrible shop will never work with them again"

"Best shop in southern Utah hands down. I took my truck into another shop knowing I needed only a water pump done but the shop told me it needed over 2500 in work done including a new oil cooler. Decided to take it over to John at kristi diesel he looked over it and told me what needed to be done. Saved me over 1500 and the work he did was amazing."

"My wife and I were traveling through Utah, on our way through to Nevada, when our truck broke down. We were towing a toy hauler, which made the experience even more fun. When we found Kristi Diesel and saw the reviews, we knew this was the place to reach out to. Very understanding and accommodating! They were very friendly and quick to repair our truck to get us back on the road. I only WISH we had high-quality diesel mechanics where I live. If they were local, they would be my absolute go-to for all things, diesel. Thank you again for such a positive experience, in a somewhat stressful situation!"

"I was traveling though and broke down just outside of St George, the local AZ trooper recommended Kristi Diesel to me. They were able to get my truck in, diagnosed, and fixed quickly. John was honest, and very knowledgeable, thank you for fixing our truck so we could get home!"

"I own a tow company with with Half a dozen trucks. If they need to go to the shop for any reason, I need a place that can do it in a timely manner, and do it right the first time. Wouldn't take my trucks anywhere else."
