Saying About Us
See why our customers consider 509 Roadside their go-to repair shop in Moses Lake, WA and the surrounding areas!
Our resident transport bus broke down on the way back from Wenatchee. 509 Roadside made arrangements to get the vehicle towed to the shop and had it fixed the very next day. Great service!
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!
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.
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.
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!
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 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!
