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!!
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.
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.
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!
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.
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.
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!
