The laziest mechanic I have ever seen. He asks you what to do. He doesn't have a shop, works on the road . Waste of time and waste of money. I recommend anyone not to call this Mexican. You will regret.

I took my Isuzu NPR Service Utility Truck in for electrical problems in the Rear Box. One Month and $1700 later, it is worse than when I brought it in. They replaced the inverter with a new one and it overloads and trips out when the overhead rear A/C is on. There is a continue draw on the 4 batteries and they discharge overnight. Oscar is never at the shop, and most of the time it is closed. Oscar never returns messages. I think that most of the positive reviews of this business are shams. I would avoid this place at all costs.

Called Extreme HD Repair on a Friday. He told me he can get to it Saturday morning, never showed up. Called again on Sunday to request the repair another time. Left a message, no answer. Called Monday morning, he tells me to text him my info. I text him. 1 hr later I call and he did not receive my texts due to "idk some bad connection". Told me he will come out. A few hours later, gives me a 1 hr ETA. 1 HR later, texts me a 25 min eta. 1 hour later, shows up. In terms of repairs, he did a good job, and helped us out with getting a part that was out of stock. Unfortunately the miscommunication caused me too much trouble to not leave this review.

I found Oscar on Google looking for help with regen he said I could come over he did a force regen while that was happening I looked at his website saw he did many other things. I had electrical outage in my truck without hesitation he went and got the parts and came back and fixed it. After all that my truck died he came right over and got the truck running. The prices we fair I FOUND A NEW MECHANIC IN AURORA CO. I WOULD RECOMMEND HIM IF you need repairs on your Semi Truck give Ocar a call.

We had to get a clutch replacement and were in a time crunch because of a load we needed to drop off. The service was excellent and got the job done in the same day. Very friendly staff and they even went out of there way to pick up parts for us. I highly recommend this shop. We will be back in the future to get the same reliable and affordable work again. Thank you!

Called and spoke to Omar about making an appointment for the next morning (Thursday) at 9 am. I arrived at 8:30 am and waited and waited. So it’s 10 am at this point and still no one. So I called Omar, he said sorry he would be at the shop in an hour. So I waited a little longer, still no one at the shop and it’s now noon. I tried calling that one more time and he did not pick up. So I don’t recommend this place at all. Omar doesn’t show up for the appointments he makes.

Oscar is one of best mechanic 🧰 in the area. I got a Hub Seal leak, I went to Loves store they couldn’t open the seal nut, even the Kenworth dealer couldn’t find the right Socket . I come to Oscar he tried his best and some how he did open and replace the Seal. What a professional, Honest and very skillful mechanic. I recommend every driver who to see Oscar if you need any kind of repair.

Knowledge about the job and fair $ for Denver area. I will use Extreme Heavy Duty again. 5 🌟 Edit \/ I had lost of power Monday. My turbo actuater wasn't working at all. Anywhere I called I was told 3 days to 2 week just to get me in. Extreme Heavy Duty Oscar came to my rescue and fix me up. start working on my Friday around noon I was ready Friday night. Truck was never better my MPH & POWER improved tremendously. The number of CALLS he gets is crazy. He can't get to everyone he is two men strong but he can only be at one place any given time and that is common in the area Thanks Oscar

I definitely recommend Extreme Heavy Duty repairs for all your repair needs. Oscar, the owner/mechanic is very knowledgeable and professional in his work. He made sure I was 100% satisfied before billing me out. I received great service at this shop for a very fair price. Very nice people and definitely will return for any future repairs.

This place is so freaking awesome. Oscar is the best semi truck mechanic in Denver Colorado and probably America. I've been to plenty mechanics all over America cause I run all 48 connected states. Hes the best I've found. He's fast good honest smart and respectful. I come to Denver alot so this will be my main mechanic from now on. Thank you Oscar!!

Our AC blower thingy broke down and was turning on and off randomly (mostly off) Called Oscar and he told us to dropby to have him take a look. Strangely he no longer works at that shop and he did not update his address on Google, but he works nearby and he came over to help us out. Long story short, he had it fixed in about 1h30mins. Very helpful and nice guy, we were melting in 100 degrees of heat and would've overpaid so much more for the same service he provided compared to all the trucking services nearby. Oscar was a godsent for sure. Would recommend him if anyone needs reasonable trucking services done.

Called Oscar explained to him my semi won’t start, we agreed to meet at 2:00pm. At 3:00 I call him he said he’s at Home Depot. It’s 4:00pm and I’ve been waiting 2 hours for him and silence… I was relying on you, you gave me your word, you wasted my time and didn’t hold your word. If this is how you run your business, it’s not going to do well. Update: Oscar called me the next day and offered to meet at my truck to take a look at it. He’s a pretty nice guy Update: we agreed to meet again and he didn’t show up again. I hope this place closes down , worst service I’ve experienced in my life. Lie to you face

Twice now I've had an appointment with Oscar and when the time came he didn't answer his phone or text me back. The address listed is for a transmission shop that he doesn't even work at, but supposedly meets his customers there. He didn't come to meet me. Good luck!

This man was extremely helpful... I went to loves then TA both shops sent me away to the international dealer they didn't even acted like they wanted to help.... So looking online I came across Oscar... He ask if I could drive to him to see what's going on... After looking he explained what needed to be done then DID IT... The next morning leaving me time to still make my delivery thank you very much!!! If your in the area don't be afraid to give him a chance am sure glad I did...

My father in law was looking for a place to have his semi truck repaired. He needed injectors, and his fifth wheel replaced. Oscar was very honest and open with him about pricing, he even let my father in law bring in his own parts. Even though he mentioned he was very busy and booked up, he managed to deliver and finish my father in laws truck within reasonable time.
