Saying About Us
See why our customers consider 509 Roadside their go-to repair shop in Moses Lake, WA and the surrounding areas!
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.
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.
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!
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.
My car broke down and Joe found me stranded. He called a tow truck immediately and waited with me, I told him I thought my alternator burned out and he confirmed that was the case as soon as he walked up. He had the car fixed first thing in the morning and his rate was very reasonable. Joseph is a great person and an amazing mechanic. I highly recommend his services.
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!
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.
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.
