Is It Safe to Drive With a Bad EGR System?
Not for long. A faulty EGR system can reduce engine performance, increase emissions, and eventually cause damage to other components. It’s best to have it inspected and serviced immediately.

A clogged DPF can cause slow acceleration, poor fuel economy, excessive regens, or dashboard warning lights. If ignored, it can trigger limp mode or complete derate. Cleaning or replacing it is essential.

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