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.

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.

Terry Robinson

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

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!

Brine Hyperbole

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.

Dan N.

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.

Dan Stout

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.

Noah Dunn

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.

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!!
