Deer Valley Diesel

To any prospective customers please read this companies reviews and know that I have tried to work with this company on a few repairs. Each repair the cost was higher than quoted and in the most recent event I will never refer anyone to this facility. The owner and manager lied and when confronted acted like they could never be wrong. THE SHOP left the radiator cap off this truck after a repair that was $750 higher than quoted. This is not a professional shop but is a bait and switch. ONCE AGAIN THEY LEFT THE RADIATOR CAP OFF THE TRUCK.

Notice that the five star reviews say nothing while the one star reviews tell the stories of how Rick ripped them off. STAY AWAY FROM THIS CROOK!! Mechanics at this shop needed three chances to make repairs and ran an unauthorized transaction on my credit card. After first repair and $1400 my truck did not make it 1/2 mile down the road. Truck was back in Rick's shop that night. After paying another $1300 and leaving his shop Rick had the nerve to call me about 30 minutes later asking for authorization to run another $700 on my CC. I sent him an e-mail telling him he did not have permission to run any more charges. Three days later he did. I am working on reclaiming the first and third charges with my bank and am filing a criminal complaint with the AZ Attorney General. BELIEVE THE OTHER REVIEWS AND STAY AS FAR AWAY FROM THIS SHOP AS POSSIBLE!!! These people literally belong in prison.

Wouldn't even give them one star but I had to to write a review. The service is terrible, the owner Rick is very unfriendly, the mechanics and Rick are all very dishonest. I paid your Valley diesel approximately $7000 to fix several issues in my truck and during 4 visits. Each time my truck came out a shop it had the same problem accompanied by a 5 to $900 bill. The 3rd time my truck was in the shop for the same issue they diagnose the transmission and charge me $500 just for diagnostic alone. I then paid $5000 for a new transmission to be put in the vehicle at closing time they called me and told me the vehicle was done and running great. Wasn't more than one mile from their shop when the vehicle began to miss fire and the same problem that I took it in therefore was still present. As I turned around to go back to the shop of course they were closed I had to wait another week to bring my vehicle back this time. Prior to the week ending I had a strong vibration each time the transmission shifted and still had a motor that was not running properly. I did not want to bring my vehicle back to Deer Valley diesel due to them not being able to fix it correctly however the transmission was under warranty and they were the ones who put it in. When I drop my vehicle back off with them I was informed that the fan clutch was bad and to U joints were bad. I authorize the repair at approximately $900. I was also informed by Dale the mechanic that there was an oil leak and that a Turbo boot would fix the problem. I authorize that repairs well and on a Friday just at closing time I was told my vehicle was available to be picked up. I pick my vehicle up from Deer Valley diesel and drove to Flagstaff to assist my brother in moving some furniture back to Phoenix on the way home the following day on the freeway my vehicle quit running. I pulled over to the side of the road and as I did the front end of the vehicle burst into flames. My brother and I jumped out of the truck and I noticed a waterfall of oil pouring out of the engine. By this time the fire department arrived the front end of my truck was completely engulfed in flames. On Tuesday morning when the shop opened I return to the shop to speak with Rick the owner about what had happened. Rickon for me the Deer Valley diesel did no work on the oil and a Turbo boot they replaced was in the front of the motor which went to the after coolers. I was not having an issue with Turbo boots or after coolers and I was told that that fix my oil leak. I was brushed off by Rick telling me to report the incident to my own insurance that they were not going to cover anything. I was already unhappy with your Valley diesel the service I received the dishonest mechanics and almost $7000 in repair bills I now have no truck and in currently waiting for insurance to cover it so that I can get a vehicle. My truck was a lifted 2002 Ford F250 diesel with a lot of custom work done on it. I will never return a Deer Valley diesel and I recommend nobody else ever use their service.

These boys were able to repair a complicated computer problem on a H2 Alison tranny conversion. Done real good.

They Over charged me, 600 dollars for a trans service. Never again will I bring a truck here. Its hard to find good people, that are fair, Dear valley diesel is a rip-off, I should have read the reviews first. They quoted me 380, charged me 580.
