Saying About Us
See why our customers consider 509 Roadside their go-to repair shop in Moses Lake, WA and the surrounding areas!
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!!
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.
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.
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!
509 Roadside saved my day. I locked my keys in my trunk and called insurance to have them help connect me with someone to get into my car. I was waiting for the maintenance truck to come, 2.5 hours after my call. 509 Roadside was just driving by and helped. Super nice guy!
Joseph helped me out when my car couldn’t shift gears coming from Spokane, going back to Western WA. It was 99 degrees out and he came from his house to help me. He was calm, knowledgeable, communicated well, and honest. He even called me when I got back home to make sure I made it and gave me some car tips. There aren’t too many people out there like him. I believe in karma, and Joseph deserves all the best karma his way.
They did excellent work on getting my 1995 Tacoma running with multiple vacuum and other issues. Good diagnosis and repair on old projects is hard to find now days. I would recommend these folks to anyone.
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.
