Emergency Mobile Semi Truck Service

No Towing. No Waiting. No Excuses.

You’re not making money sitting on the shoulder of I-75. That’s why we bring the shop to you, whether you’re dealing with a blown tire, brake failure, or engine trouble.

Most breakdowns that strand drivers for hours get resolved on-site in a fraction of the time. Our mobile units carry the diagnostic equipment and common parts needed for immediate repairs. When we can’t fix it roadside, we’ll get you to our shop or arrange proper towing – but that’s the exception, not the rule.

The difference is having technicians who understand that your truck is your livelihood, not just another repair job.

Trenton Semi Truck Repair Experts

40 Years Fixing What Breaks Down

We’ve been handling roadside emergencies in the Detroit metro area since 1999, building on over four decades of diesel repair experience.

Dr. Phillip Marin leads our team with three Ph.D. degrees in Diesel Engineering, Drivetrains, and Metal Alloys. That level of technical knowledge matters when you’re diagnosing complex engine codes or troubleshooting electrical systems that leave other shops guessing.

We know the I-75 corridor, the truck stops, and the routes that keep Southeast Michigan’s freight moving. When you call us, you’re getting locals who understand both the technical and practical sides of keeping trucks running in this area.

Mobile Truck Repair Process

From Breakdown to Back on Road

Call us and we dispatch immediately. Our technician arrives with diagnostic equipment to identify the problem quickly – no guesswork, no trial and error.

Most repairs happen on-site. We carry common parts like brake components, belts, hoses, and electrical components. For tire issues, we handle everything from repairs to full replacements right where you’re stranded.

If the repair requires shop work, we’ll either tow you to our facility or arrange transport to a location that makes sense for your route. Throughout the process, we keep you informed about timing, costs, and options so you can make decisions about your schedule and cargo.
