Diesel Service Reviews

“Super friendly and quick. Spence helped me to get the plastic unwrapped from my tire and was fast to diagnose my check engine light. Even though they were super busy he was able to get me in and on the schedule. I’m new to NOCO and will def be bringing my vehicles here.” – Rachel J.

“I brought my husbands truck in for emissions and learned they were also a full service repair shop. They were friendly and we ended up bringing his work truck back for a head gasket repair and were treated well. The repair was made correctly and we haven't had any issues with the truck since. We're happy with the service and repairs, we will return and definitely recommend this shop if you need you diesel worked on.” – Jessica C.

“This place........this place is absolutely the BEST place to go!! The whole team is just simply amazing! Best Experience a person could have! A HUGE SHOUTOUT to MONDO!!! He is the most understanding, helpful person we have ever dealt with! He worked with us on everything and called to discuss problems BEFORE fixing them so we weren't shocked at the end. We will never go to a different shop and we will make sure everyone knows to take their business to Rocky Mountain Diesel and Auto!! Mondo, we cant thank you enough for everything! Your the Best!” – Amanda W.

“They saved me a ton of money I was told I needed new injectors and they took a look at it and just repaired Instead of charging me for something I didn't really need” – Adam J.

“2014 ram 2500 6.7 , they got my new turbo actuator installed and calibrated also fixed some leaks , from drop off to pick up they diagnosed and fixed in a short period of time and the truck is now running great. Also was fair on price, I will definitely take it back for future work.” – Bryan C.

“Best run garage I’ve been to. Was stuck with low fuel pressure light and had to leave the pickup for repair. Left package in back seat but they delivered them to my door. Great customer service and caring for their client. Everyone is knowledgeable and quick to get me back on the road. Wish there was a shop like them in every city along my travels.” – Jerry A.

“Had electrical gremlin and while it took some time to figure out, they were persistent at helping me solve my problem. Thanks to Mando, Tyson, & Spencer for being diligent and patient. Services provided were; Oil change, replaced def pump & heater, cleaned out def tank, replaced faulty cam shaft position sensor, & solved intermittent electrical issue.” – Aundrea P.

 “Mando was very professional. Took their time to figure out the problem with my truck when I was at ends to finding the problem. His staff took their time and located the issue when other shops had no idea. I was patient and the results were good. I would highly recommend them to anyone, as they have been very helping with myself and my families diesels.“ - Tim T.
