Amazing service everyone there was awesome fixed my truck perfect have now put 50,000 miles on it and still no problems thanks everyone at under ground will for sure be coming back
I am EXTREMELY DISAPPOINTED with their service. They had my truck for ONE MONTH(exactly 4 weeks). I placed at the very least 30 calls to their shop, over the 4 week period, just to try and get updates since they had it so long. Probably only 4 or 5 of my calls were answered during the entire 4 week period, and I NEVER received a return call from them, even after having left messages. I had to get lucky and call at the right time for them to answer. The problem ended up being the fuel pump, and a fuel relay module. We discussed putting an after market upgraded Air Dog system on it which they highly recommended. So I agreed to it. The one call I did get was to come pick it up. Cost was roughly $1,000. Their website advertises $89 an hour shop rate, I was charged $95 an hour. Before I got the truck home, I could smell diesel as I was driving down the road. I stopped and opened the hood to see diesel fuel all over the engine compartment. I called them immediately and of course got no answer. When I got home I took a closer look and found that the old line that they supposedly "capped" was leaking diesel everywhere because they stuck a bolt in it with a hose clamp(didn't work guys). I'm not even sure why there would still be any pressure on that line, they told me it was bypassed. Additionally they mounted the Air Dog system on the frame where it actually hangs down below everything else. I asked about that, and said that I thought it was going to be a problem(for clearance). The response I got was, "do you go four wheeling a lot?". In my 4 wheel drive truck??? Yes I do, that's precisely why I bought a 4 wheel drive. I will find a better spot to mount it myself. I don't have another month to wait without my truck. Also, the Air Dog system they installed is so loud, I can actually hear the pump while I'm in the cab, over my Cummings diesel motor while it's running. I think everyone knows how loud a Cummings is. It's even louder and more noticeable when you're standing outside next to the truck. I realize UDP doesn't make the pumps, but they might want to consider a better location for mounting it, if it's that loud. The only good thing that did happen, is that they sent a tow truck to pick up my truck free of charge. I've had complete transmission rebuilds, and engine replacements done in a fraction of the time, with better quality of work. I had heard they do quality work at UDP, but I can't even agree with that. In my opinion they did a poor job on the Air Dog installation. I WON'T BE BACK. It was an OVERALL POOR EXPERIENCE.
Most unprofessional shop out there. Do not answer or return calls. Had vehicle for over two weeks and nothing was done
If the owner could please call me I would appreciate it we are having some issues with not getting so parts we have ordered over a year ago from you!!! Phone # is 573-243-1442
Absolute Best!! I have 2 Dodge Cummins Trucks for my company and I have been to a few shops in town, including the dealership. I have to say that I am 110% happy with the work Underground Diesel has done for me and my trucks. Great service, Professional guys, and they have a passion for the diesel industry. Its nice to roll up to a shop and see nice pickups out front, rather than a bunch of old cars and junk. Ask them to show you the shop, as they keep it very clean and organized. As a business owner that says a lot about a company. They are very fair and up-front with you. If you want the best for your truck in Las Vegas, see these guys. Thanks again Underground Diesel!
You will not be disappointed with not only the quality of work but the customer service as well! Awesome group of people in this shop!
awesome customer service, and quality work!
This is truly a top notch shop! Very confident and knowledgeable staff that takes pride in their work. Service area is clean and organized, my truck had protective fender covers on it while service was being performed to avoid any blemishes. Its hard to find quality and trustworthy shops these days, especially in the aftermarket/performance industry. Great Service, Knowledgeable Staff, Truck Hauls A**! What else can you ask for? Thanks UDP!
Overall the best diesel repair and performance shop I have ever been to. Friendly, helpful, and very knowledgeable staff. I would definitely recommend Underground Diesel Performance to anyone looking for a shop that actually knows what they're doing. Simply put they are the best!
