Deer Valley Diesel Repair 19443 North 39th Avenue, Glendale, AZ 85308

"Deer Valley Diesel is our "Go To" shop when we're in Phoenix for repairs or maintenance on our beloved 45ft 2008 Monaco Signature and our 43ft 2006 Fleetwood Revolution. Rick Cortez and his crew of diesel mechanics are the top of the line when it comes to repairs and maintenance of anything diesel. You will not be disappointed!"

"Ripped my door at Walmart in Phoenix on Saturday...Daniel came to me and repaired my door in 3 hrs..Great Job.."

"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."

"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."

"I was charged diagnostic twice for the same problem and I was told that my Turbo needs to be replaced. I received a quote which we agreed that I will bring in the vehicle after my vacation. I had to find out that the company did not honor their own quote, but gave me another diagnostic and a higher rate. They claimed that it is also the alternator. The repair suppose to be with the diagnostic about $3000 plus the alternator and whatever else would come with it. I decided to bring it to a different shop. The Turbo was not broken and neither was the alternator. It was a relay and and some small connection parts. I paid a lot less and I'm glad that I took my vehicle out of this shop before they took it apart. Be careful!!! They try to screw you. If you are not a pro than they will give you high bills and count on that you are not finding out the truth. The owner Rick is the worst. He charged me for a diagnostic which was never done. Otherwise he could have told me what the real problem is, since it was not the Turbo itself and neither the alternator."
