    Attention to detail!! All exposed wires were reloomed!!

    George is the man! Super helpful, super knowledgeable, and works super fast to get your truck running flawlessly ! My 07 LBZ Dmax went in for a head gasket job and i got it back running better then ever. If you're looking for a good, reliable, and affordable shop look no further. They are super detail oriented and go above and beyond to make sure the job is done right and you're satisfied. Thanks again George!

    10 out of 10 service Diesel tune is number one in my book Every time I go in there, they knock it out of the park and go above and beyond. I'm just very thankful this is a shop that you can trust. I would highly recommend this shop. All my friends and family come here.

    On my way back from a trip up north, a check engine came up on the dash. A friend from work recommended this spot. I dropped off my car for 2 hours to have it diagnosed and they told me there was a loose connection in the fuel injector system. They fixed it and brought my baby back to life. The final cost was also very good considering the fact that a dealership would charge you 3x extra and misdiagnose you. If you need something done, get it done with Diesel Tune. Speak with George or Freddy, they know what's up.

    See all

    George was great, he informed me about everything they were doing and checked with me before doing anything.

I want to thank Jay who helped people the day I went. The facility was clean and organized, so I felt very comfortable about coming here. They are next to car wash and a gas station. Also, Stonewood Mall is across the way too. The had coffee and snacks, I loved that they had Kirkland coffee pods, oh heck yea. The waiting area is not huge but enough. Jay was very knowledgeable and helpful; I overheard him helping people out. As far as value, I felt I got a good value, as I was shopping around. I was given a time estimate, and a time estimate if I wanted additional service and they were very good about meeting that. I got a free car wash at the was station next door, full service, and they did a great wash. I am already planning my next visit with them. I will update review in the future.

When I pointed out the banner at their shop that says "Free Brake Inspection" and their website which states Free Brake Inspection, he retorted that their website also states they do free smog checks, but he states they do not even do smog. (When relooking at their website, they do not mention free smog anyways.) Lorenzo stated the brake inspections were not free and the website got it wrong. When I asked him for the person in charge he stated Erika and Ezekiel were in the parts dept. It is a shame Lorenzo was the only advisor handling a long line at check in. He stated Corporate was aware of the brake inspection charge discrepancy. If they are aware and he is aware, why try to charge a customer for a "Free" brake inspection? After leaving our car here, we heard the next day of a list of repairs needed. Lorenzo stated they believed our brake caliper was seized but could not confirm it. He attempted to charge us an additional $289.47 for the brake caliper service and $152.10 for the brake fluid service in addition to the brakes and rotor replacement service charge we were expecting. The issue is that when we asked Lorenzo if he could confirm if the brake caliper was truly needed to be replaced, he could just say he highly suggests replacing it. From the beginning, this place was trying to scam. I reached out to Alex's Auto Repair in Cypress, who confirmed they could verify if the brake caliper would be needed. Alex's Auto Repair stated there would be no need to waste extra money if he could confirm the issue. Alex's Auto Repair serviced us, and simply lubricated our caliper without us needing to pay over $800 for the whole brake service like Downey Care Care was quoting us. Alex's Auto Repair took the time to verify the issue, charging us less than half of what Downey Care Care center wanted to charge. My issue with this location is they would have happily overcharged us for a service that was not needed. Take your car to Alex's Auto Repair, save your time and money. While Downey Care Care Center was busy playing around, we had to spend extra time and money booking a rental car. (Photo on the left is from Alex's Auto Repair who took the time to verify the concern and lubricate our caliper. The photo on the right includes one page of many pages of services recommended by Downey Care Center including replacing the brake caliper and fluid exchange had we chosen to go that route.) Makes me question if the remaining suggested repairs (not all pictured below) by Downey Care Care Center were even necessary.
