What Is Preventive Maintenance?

Preventive maintenance helps catch problems before they become breakdowns. We perform oil changes, fluid services, inspections, and filter replacements to keep your truck running longer and avoid unexpected repairs.

What They're
Saying About Us

See why our customers consider 509 Roadside their go-to repair shop in Moses Lake, WA and the surrounding areas!

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.

Devon M

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!

Rocio Mendoza

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.

B.W.

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!

Erin Walkup

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.

Matthew Cummings

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!

Cheryl Hall

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.

Mickey Burk

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.
