Saying About Us
See why our customers consider 509 Roadside their go-to repair shop in Moses Lake, WA and the surrounding areas!
I am a hostler driver in our yard and anytime I need repairs, I call on 509 roadside, they haven't disappointed me at all. Very professional and courteous, I strongly recommend them.
Totally helped me out of a jam. Last Wednesday 2/26/25 late in the day, my 2011 Isuzu Blue Bumper Box truck had a red check engine light go off. You guys were my angels. Thanks so much for clearing the code and getting my truck back on the road. It made it all the way to Spokane and back to Seattle.
I can’t speak highly enough of the service I received from 509 Roadside. My F150 was throwing multiple error codes and knocking, and eventually stranded me off I90 on a Sunday afternoon. Joseph with 509 was extremely patient and attentive, and helped walk me through problem solving over the phone, and I was able to get back on the road. (For a bit, but that’s the truck’s fault and not theirs!) Five stars, and I’d give more if I could.
Joseph did a great job replacing a small engine for us. He searched, bought and replaced it for us while keeping us informed every step of the way. With great pricing and service, we will continue to utilize him in the future for our needs.
My window wasn’t working for the past 2 years and I was looking for a good mechanic for a while but they were too pricey. But 509 roadside did not disappoint! They were able to fix my window at a great price! Definitely recommend!! I can finally go through the drive through!
I started using 509 Roadside in 2023 and I can’t say enough good things about Joe and his team. They provide prompt and professional repair services for my equipment at very reasonable rates. Since my office is based outside of the region where 509 Roadside is located, they are a strategic resource for my equipment service needs.
These guys got me in to their shop on short notice and found my electrical problem quickly. Can’t thank them enough! I will call them again if I need help in the area!!
509 Roadside put in a left foot pedal, brand new brakes, and rotors and rear drums on my car. Also checked all fluids and cleaned engine bay. They were fast, friendly, and went way above and beyond for me. I would give these guys 20 stars if I could!
