If you own a diesel anywhere near Berea, KY, save yourself the trouble and call Preston Jones at PJ Diesel. I brought him my 2021 Silverado Duramax (L5P) and the whole experience was as good as it gets. Preston is honest and upfront with you from the first conversation. He got back to me fast every time I reached out, and the turnaround on my truck was quick. He knows these trucks inside and out, and his pricing is fair. He came in less expensive than a lot of other shops, and the work is excellent. What really sets him apart is how he treats his customers after the job is done. Any time I've wanted to pick his brain about my truck since then, he's been glad to share what he knows. My truck is running better than it ever has. I'm in Richmond, and I would've driven a lot farther than that for work this good. A reliable diesel mechanic you can trust is hard to find, and I couldn't ask for anything better. I'd recommend PJ Diesel to anyone in Madison County or beyond.

FREQUENTLY ASKED QUESTIONS
Have your truck's year, make, model and engine size on hand. If you're getting a check-engine light or you've heard a new sound, describe it. If you know your current mileage, that helps too. We'll ask a few questions to understand the problem before you drive in.
We're open 24 hours, 7 days a week, but it's always a good idea to call first. That way we can talk through the issue and make sure we have what we need to get your truck running right when you arrive.
We plug into your truck's computer, read all the fault codes, and run tests to isolate the real problem. We'll also inspect the engine, fuel system and turbo by hand. Then we explain what we found and what it costs to fix it before we do any work.
Diesel engines are different from gas engines. The fuel system, the turbo, the injectors, the fuel pressure all run different. We work on all brands, including equipment and semis, so we find problems other shops miss and get your diesel running strong.
We offer service for all brands, not just Duramax, including equipment and semis. Call and tell us what you're running.
