Temecula Diesel Truck Repair

I didn't actually get service at the shop but the gentleman that took my call was EXTREMELY helpful. I have a little diesel, 2.8l duramax, which they don't service, however, I was given information to help troubleshoot my issue. Having someone that is even willing to have a discussion is rare but not here!! Thank you so much!

I have been going to Temecula Diesel since 1991, and in that time that Ken, Bower owned it, he always ran as a 4.5 to 5 star operation. Ty , for your information I was lucky I made it to AZ.. When I called you about the steering problem, it was the steering box, but after they repaired it they noticed another oil leak which was coming from the middle of the motor area. When they found it, it was coming from the turbo base. When they removed the turbo base they discovered that you did not replace the gaskets, instead you used liquid gasket material, the turbo base bolt holes were cross threaded. So, instead of replacing with a new base, you used the same base with the same bolts, which is not recommended from Ford, which you should have known. Instead you used the same base, bolts, and thread coils instead. Also, you did not put new gaskets, used liquid, did not replace rubber seals in port areas in the turbo base,instead used existing seals ,in which the main one was split and smeared with gasket sealer and that is where the leak came from. Total rookie mechanics. This is the result of waiting 8 mos. to resolve and this is what I received. Ty, I do not know what's going on lately, but I'm very disappointed after all these years in how you conducted this whole situation. If you want to confront me about this situation to prove me wrong,of which I have pictures and parts,I will gladly do so, you have my number. This has cost me more time and money, in which I do not think you will ever consider helping in any of the cost. Through all of this ,I have had one week of use since I turned it in to you last Nov..

After several frustrating hours of calls trying to find someone to help us after we damaged the tailpipe on our RV, we pulled in and I threw myself at the mercy of the mechanics. Despite it being 20 minutes until closing, Eddie took care of what he saw as a minor problem. To us, his kindness was priceless and gave us peace of mind to continue our travels. It is perhaps easy to watch the news and conclude that most people in our country are cold and self-centered. Eddie is a shining example refuting that thought. Thank you many times over.

Great mechanic, fast repair time, and they did a excellent job :-) The only downside is you can't bring your own parts for them to install. That is understandable because they do warranty their work and I'm sure they don't want to be on the hook for defective parts that they did not source. However a option just to pay them to install something would be nice.

Do not waste your time or money coming here! If I could leave negative 5 stars I would. We brought our company truck in because it would not pass Smog back in FEBRUARY of 2022 and after weeks of no communication and being given the run around, I was told they were attempting to order a part that was back ordered nationwide. We are understanding and know that parts are hard to come by since COVID but that is no excuse for the extreme lack of communication. EIGHT months later we finally got our truck back only for the check engine light, check service emissions light, low coolant warning (false warning due to bad sensor) and a warning stating the max speed is capped at 55 miles per hour to come on just two weeks later. The owner Ty lacks basic customer service skills, and his guys clearly did not know what they were doing back there. I had to take it to GMC Temecula for diagnostics only to be told that what we paid Temecula Diesel to do needs to be completely replaced among varies other things that should have been addressed by Temecula Diesel. I thought to bring it back to them but after being told they “wanted to keep over night and test some other things in the morning” I just knew the best thing would be to take it to an actual dealer or run the risk of not having a our truck back for who knows how long.

I took my truck to them and weren't able to do much to it even though they had the truck for mouths and still had the nerves to not put my truck all back together.
