Rapid Diesel Repair Reviews

Brought in my 2019 ram 3500 because it had an EGR code. The dealership wasn’t able to touch it for almost a week. These guys got my truck in fixed plus also did additional diagnostics which showed additional issues. They got it all in and out in a super fast time frame so my family and I could enjoy a vacation. Highly recommend.

After having a mobile diesel company come to my house which ended with 2 techs come out and charge me for over an hour of basically guessing what the problem was. I got a flyer from a diesel repair shop Rapid Diesel repair in Rancho Cucamonga towed my truck there they found one of the issues where my truck wouldn't communicate with a scanner which was caused by the techs that came to the house broken ground wire from the battery to the ECM from there Rapid diesel was able to find injector in cylinder #5 was bad and needed to be replaced . They recommend to replace all 6 injectors and at 231,296 miles and definitely agreed and here it is Friday and im picking my truck up . The guys here at Rapid Diesel Repair are very friendly professional and the first thing they did when I got there was give a great welcome got a tour of the shop ( I've never seen a shop this clean and organized with quite a few trucks being diagnosed worked on etc. These gentlemen told what was going to happen and thats exactly what they did so a BIG THANK YOU to Rapid Diesel Repair for a quality and professional costumer experience and a scale of 1to 10 I'd give them and 11 !!!!!!!

I’ve brought my trucks to Rapid Diesel Shop a couple of times now and have had a great experience each time. Robert is great—very knowledgeable, honest, and always willing to help and answer any questions we have. They’ve replaced both a radiator and a driveshaft for us, and we haven’t had any issues with the work. One thing I really appreciate is their communication. They kept in constant contact with us throughout the repairs and provided updates along the way, so we always knew what was going on with the truck. Their service has been fast, reliable, and professional, which is especially important when you depend on your trucks for work and need to get them back on the road as quickly as possible. Definitely recommend Rapid Diesel Shop if you’re looking for knowledgeable mechanics, good communication, and quality work. We’ll continue bringing our trucks here whenever we need repairs!

These guys are great! Brought my 2016 Ram EcoDiesel here and they did amazing work. Thorough and detailed work recorded and extremely friendly. Robert was great and did a fantastic job making me feel comfortable and when I arrived to pick the truck up they had it washed and he took me on a walkthrough of all the work done. 10/10🔥
