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.

It depends on usage and mileage, but most trucks benefit from service every 10,000 to 25,000 miles. We’ll help set a custom schedule based on your truck or fleet’s 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.
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.
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!
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!
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.
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.
