I needed quite a lot of repairs recently on my truck, which is a 2014 ram tradesmen. The folks at the shop were absolutely beyond helpful. I had a very tall list of things I needed fixed and they did all that and more for a fair price. I basically needed a new truck when I walked in there and left With exactly that. Marcus treated me with patients and they finished my truck in incredible time. I would highly recommend coming here to get your diesel running the best it ever could. read more

Friendly, competent and professional. Got me right in and fixed the issue. Family run business.

Without a doubt, the people that work here are all very nice and professional. It's very much a family business. I do believe they do good work, I chased an oil leak for almost 2 years and they seemed to be able to fix it... I've only had the van back a few days so I can't save for certain it's 100% fixed, but so far so good! Yeah, they are expensive, but so far they seem to do high quality work, which to me, is worth the price. read more

An unbelievable experience with Dierks Diesel! The truck is a 1995 Dodge Ram 2500 diesel, the problem, mega smoke when starting the truck first thing in the morning, every day without fail. Also, there is a small leak from under the front end of the truck. Dierks Diesel is where I dropped the truck off to get fixed, you know the rest, we'll look at the truck, blah blah blah. The point of the experience, receive a text that the truck was ready and come take care of the invoice. 3100.00 and change. Fair enough, upon leaving his last words to me were, "The truck hasn't been started all day, no smoke" Started the truck, no smoke, got this warm feeling, no smoke, YIPPIE!!! Brought the truck home, parked for the night, ready for tomorrow. Have to do a dump run, looks like 3 loads!! Good Morning, looks like a great day to get the garbage to the dump. Let's get the truck started and loaded, busy garbage day for me!! What the hell, smoke, smoke, smoke and more smoke and now leaks in four places. Oh dear, this is not fixed, no really, you can tell!!! ok, what to do? Well, walk away! Sent a text saying "the truck still smokes and smokes and smokes, unbelievable!" Had to chill a bit so off to cut the grass, really helps me think. Back from cutting the grass, a missed call, it is him, simply sent a text saying "I will take care of it, thanks!", then blocked the number. I think to myself (what a wonderful world of course) but I feel like I just got robbed. Anyways, the phone number is blocked. Not sure what the response would be, maybe bring the truck back, who knows, who cares. Why would I return the truck for repair repair after the first repair was incomplete, honestly you can tell! Just does not seem like a place for my truck to continue getting work done! So, I walk away into the sunset, wondering if anyone is out there that knows how to work on diesel trucks, again, I find myself on a quest for knowledge, the Dodge will get fixed. It is just that Dierks Diesel does not work for me. read more

Had my 2006 F350 Diesel with less than 100,000 miles on it towed to this place. We are the original owners and this truck is stock except we changed it over to a flatbed. This garage came back to tell me that they had no idea what was wrong, suspected the typical issues with this engine to be the cause, would repair to better than OEM and or good as new. The mechanic who was super nice told me to go read blogs about the typical issues for this engine so I would have a better understanding about what he was talking about. I repeat, no concrete diagnosis, could be this and that...and here is the kicker...$11,000 for a top half of engine fix. Everyone I knew told me to get it out of there, but first I called around and chatted with other reputable diesel shop (from great reviews) and they all told me that they would absolutely be able to diagnose the issues before commencing any work. I had it towed away to a top diesel shop and they have diagnosis and it's less than half of quote that Dierk's shop gave to me. Adding insult to injury, they charged me $500+ to diagnose without a diagnosis, stating that they spent 3 hours going over the engine. I WOULD NOT take another diesel truck there ever again. Of course after I got my truck out of there and told a few people about my experience and what they charged me I found out how many other people have had bad experiences when they took their trucks to this place. Sucks for me, save yourself and take your diesels to a reputable Spokane diesel shop. read more
