Denver Diesel & Automotive

I’m simply going to lay out the facts and you can decide whether you want to do business with this company or not. Little background so this timeline makes sense: Zimmerman (upfit manufacturer) and Denver diesel need to work together to get the job done. June 2024 –I called Evan (Denver Diesel). I spoke with him about a potential head gasket repair on my Mercedes engine MBE4000, and he sounded confident that the job could be done for $6,000.00. The point of me planning this early is so the repairs can be done efficiently and quickly during the winter months. As repairs in my busy time are beyond costly. Denver diesel had the truck on their schedule since mid-summer 2024 to go in the first week of December. December 3rd the truck arrives to Zimmerman first. Zimmerman reviews the truck to get his list together. Denver requests the truck be brought over to them right away as they were signaling to get on it right away. So, Zimmerman did so. December 6th Denver diesel communicates to Zimmerman that they want the truck and only need it for a week. ** NOTHING IS DONE TO THE TRUCK – NEVER MADE IT INTO Denver Diesels SHOP ****** December 23rd – Zimmerman reaches out to Denver Diesel to see what going on. They say there behind and with holidays going to get it in after 1st of year. ***** AGAIN, NOTHING HAPPENS TO THE TRUCK ******** ALMOST 2 months later! January 30TH – Zimmerman talks to Denver Diesel, and they just got truck in there shop yesterday. I’d assume if you’re reading this and have a truck you probably know that a Mercedes engine is impossible to get parts for. I knew that and I assumed a professional mechanic knew that. They tore the entire engine apart and then decide to look for parts. You cannot get parts needed to do this job quickly AND there is no place in the country that can guarantee a timeframe they would come in. This was going to ruin my spring – EXACTLY what I was trying to avoid. I research and realize that the problem could be solved with a new engine. Denver Diesel says new engine can be installed for 50K. I essentially bail them out of the situation by telling them to just install a new engine. January 30rd – March 31st - There is multiple stages of “check in’s” with Denver Diesel. I don’t have enough Review space to give much more details. Basically, Denver Diesel just continually tells me “it will be done next week or in the next couple days”. This goes on and on and on. Then, they can’t get it programmed. I specifically tell Denver Diesel the High idle switch need to be programmed on 2 or 3 occasions. High idle does not work when picked up and had to go back. **ALMOST 4 MONTHS LATER *** March 31st we get the truck back I was budgeted to spend 50K for a new motor install. There was some other Incidentals budgeted at 10K. So, I figured 60K total WITHOUT ONE COMMUNICATION about price THE ENTRIE TIME I GET A BILL FOR $80,000.00 Now there is issue with the work: - Oil is leaking – still trying to track this down - Power steering box is leaking – this was completely replaced and re-built - A bunch of coolant lines blow off on our first delivery. None of hose clamps were tightened. LEAVES US STRANDED ON SIDE OF ROAD - Faulty hose clamp on the oil dipstick – lost oil - Blower fan was to be fixed with new resistor – not working *I spend $24K+ to buy concrete from other people to keep my business running *He charges me for the tear down of the old motor *Charges tax on labor *I had multiple mechanics look at bill and no one can figure out why he had so many hours into this. Feeling very ripped off. * I couldn’t sell the old motor because it was in pieces So, what led me to this review - I could get the truck fixed for approximately $2,000.00 locally. He refused and I'm sure he's going to respond on here that he was willing to fix the truck and stand behind his work. He would only do that by inconveniencing me. If this is still up - He is unwilling to pay $2K to resolve

Highly recommend. Stopped in with no appointment and was in and out fast and without breaking my bank. Jimmy went above and beyond to get my car running right again. Upfront, honest, and a damn good mechanic.
