John’s Diesel & Auto Repair

In Sept. 2015 my wife and I were passing through Nevada pulling a 5^th wheel trailer when our truck started overheating. We exited the freeway and went to John’s Diesel Repair since our truck is a diesel. We had some parts replaced and had to stay overnight at a trailer park. A fan belt had frayed and caused a leak to the power steering and damaged wiring to the clutch fan. These were repaired and replaced at a cost of over $ 700. We were assured it was fixed and sent on our way the next day. A few miles out of town the truck started overheating again. We limped into St. George Utah as the truck was going to the red on the heat gauge. Very lucky the engine was not ruined. We found Pro Auto Care where the mechanic diagnosed the problem and said it was the clutch fuse that had caused the overheating. He replaced the fuse and charged a total of only $ 40. I highly recommend Pro Auto Care. Great service and very honest. As for John’s Diesel repair, they highly overcharged us for the parts and work they did and then did not fix the problem. Our truck was almost destroyed and we could have been left stranded on the freeway in the desert heat. In is inexcusable that they did not check the clutch fuse which is about a 25 cent item. Instead they replaced the clutch fan at a cost of over $ 400. I do not know if this was dishonesty or incompetence but either is inexcusable.

Awful service! Very rude and dishonest. He did not talk to me even when I tried telling him what was wrong or when I would ask him questions. He looked at it for a little and then just declared he couldn’t fix it. he said he would buy the car off me for parts. I sent him the title later and have never heard back from him and ignores my calls. This guy scammed me. Dont trust these people.

I took my car in and asked if they could diagnose what was wrong with my car. The guy hooked it up, shut off the check engine light and told me I was good to go, when I asked what the code was so we can get it fixed. He said you have a lot of codes but your good to go. An hour later as I was driving into Saint George my car stalled on the freeway on ramp, and I was rear ended. And sure enough there was my check engine light I asked him to look at. I ended up taking my car to autozone and they diagnosed it for free for me that I had miss fire in bank 1, that was causing my fuel to be either to rich or too lean, and it caused me to stall.
So now I have to fix a bumper, trunk, and the misfire. Thank you Johns diesel for not only risking mylife, but my two young boys. I will not be going back to you, and I surely won’t recommend anyone else ever go back to you either.

This place was a lifesaver tonight when I needed help with my car. Someone was available to help me after hours, he met with me quickly and did exactly what I needed. I highly recommend them.

There customer service is horrible. The guy answer the phone is very disrespectful. They defiantly need someone more professional answering the phone and working the office.

I highly recommend this repair shop! My husband and I owned a repair shop for 10 years! Back in the70’s and 80’s. We broke down and could not get the RV going! Called and John’s Auto responded ASAP after 5:00 pm there closing time. Told us what they thought the problem ways we said should we have it towed to your shop? The response was no they could get the 36foot RV back to there shop and they did!!!
It was a Friday night John drove us back to the hotel and said it would take 5 hours to remove the fuel tank and replace the new fuel pump!! At 9:30 am we get a call the RV is ready to go !! Boy was it ever we went 270 miles made it home and had already gone 1200 miles in it running brand new! Not to mention they picked us up at our hotel and took us back to there shop! My husband and I feel this auto shop was well worth A plus plus! Thank You John’s Diesel!!! For making a nightmare into a true adventure!!!

Called them for a tow and their tow truck broke down on the way to pick me up. Charged a higher per mile than I expected. They wanted to let them give an estimate to fix my truck, i said go ahead and look at it. They charged me $ 85 for them to tell me it didn’t have any coolant. Stay away from these guys, they are out to get your money with little service.
