    Ive took 4 or 5 different diesel trucks to them with 100% satisfaction. They have the knowledge and technology to diagnose your vehicle without all the guessing that other shops would do. There isnt a diesel shop in 100 miles that has the knowledge or experience they do. Customer service goes above and beyond. Highly recommend

    Forwarding for someone else. Apparently this is not an isolated experience: Experienced the worst customer service ever at Diesel Powerhouse by one of the owners named Jeff! If he tells you repairs to fix your vehicle are going to be $4000 he expects you to just pay it and don’t ask any questions because he will get really nasty with you if you do. Needless to say lost all future business and will drive our truck over an hour away for repairs.

    **Machine shop review** Jeff was very professional in the two cases I reached out for assistance. 1) I needed a repair on a part that had a broken bolt in it. Instead of charging me for an hour of labor to remove the bolt, Jeff looked up the part number that was lesser than his hourly rate and directed me that way instead. Thanks for this advice and being honest! 2) Another broken bolt - odd angle on the turbo for my duramax. Jeff was able to knock out the bolt and repair the threads as requested. Thanks!

    Beware! Do not take your truck here. The shop manager is unreasonable. I was completely stranded when my truck broke down 2 weeks ago and I live 85 miles away. Here is the short version of the FACTS. It took them 3 days to diagnose (I called early morning day 1 to explain to them what I thought the problem was-lifter cover gasket on Cummins 5.9 24V-which is what it was). They quoted me ancillary work and 8 hours of labor total, that didn't need to be done such as oil filter and fuel filter. Additionally, I Over the phone we negotiated to not do the extra work and that my truck has an air dog system which relocates the lift pump and hoses out of the way=even less labor. The truck took them until Monday of the next week (5 full business days). They would not adjust the labor even though they agreed to not do the extra work. The shop manager was emotional when I tried to discuss this with him, and would not compromise for even .5 reduction in labor. This business is not BBB accredited for good reason!
