What Our customers say

"The thing that really sets these guys apart is that they actually drove the truck for a fair amount after all service was done to insure that there was nothing that was overlooked and that the problem had been repaired. I can’t count how many times I’ve taken a vehicle in for service elsewhere only to drive away and find out something wasn’t tightened down or the issue is still present. I’d highly recommend Priority Diesel Performance to anyone looking for a solid shop to work on your diesels."

What Our customers say

"We highly recommend Priority Diesel Performance in Prineville as they have work done work on our Dodge 2500 Cummings Diesel truck for both maintenance and custom work. They were great. We trust them 100% and highly recommend them to anyone seeking honest mechanics.  We appreciate the expertise of the entire staff who helped us. They went out of their way to help on rather short notice and aced it!!!  Professional, quality work and friendly."

What Our customers say

"The guys at Priority are top notch!  From quoting to scheduling and the completed repair, they were awesome to work with.  They got my wife’s expedition finished on time when we were on a tight schedule and they even charged me less than quoted!  I can’t recommend them enough!  Make Priority Diesel your top choice for any automotive repair.  And no, my wife’s expedition isn’t a diesel!  They will work on SUVs too!"
