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!
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.
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.
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!
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.
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.
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.
