I took my 2024 Ram 2500 in for service due to an issue with the map sensor. Jonathan and his crew went above and beyond. They were able to fix my issue quick and while they had it I had them add some upgrades. The truck runs better than it ever has and the work they did was very professional. Definitely recommend

I brought my 2008 F-150 by to have a problem diagnosed and was impressed with the honesty and transparency. He explained the issue clearly and didn’t try to sell me anything I didn’t need. It’s hard to find a mechanic you can trust nowadays but this is definitely one of them that you can trust. I highly recommended Red’s diesel and auto repair.
