Saying About Us
See why our customers consider 509 Roadside their go-to repair shop in Moses Lake, WA and the surrounding areas!
509 Roadside is amazing. I was driving my truck and was in the area with an airbag broken on my trailer. I called 7 different shops within 100 miles of Moses lake around 1pm on a Thursday 3/13/25 and 509 was the only one to answer. Not only did they answer but they took the time to find the correct airbag and get me safely back on the road at a very reasonable price! It was a great experience and I will definitely be using their services again if I’m ever in need.
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!
Had my starter go out they had a new on hand and I was back on the road right at 2 hours, great job 509.
Joseph and the 509 Roadside crew have been an invaluable part of keeping our fleet of delivery trucks running reliably here at Culligan, and it has been great having such a fantastic, local mechanic. He is consistent, thorough and always goes the extra mile to ensure our vehicles are in excellent condition. His attention to detail and commitment to quality work are evident in every job he takes on. Knowing we can count on him for fast, dependable service makes all the difference in keeping our operations on schedule. Very highly recommended for all your fleet needs!
Had issue with semi shutting down due to coolant level issue, contacted 509 to assist and they were earlier then expected, very friendly and got me back on the road quickly and went beyond duty and even checked other things to prevent any other issues. Would call them first if I ever have a problem down road.
The customer service is excellent. They follow up and get the job done in a timely manner. I would recommend them for any type of mechanic work.
Came in for an issue, fixed extremely quick. The most honest mechanics ive seen in a long time. Will definitely be coming back for any future issues!
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.
