Hear from Our Customers
You’re not just getting your truck fixed—you’re getting your schedule back. Our mobile semi truck repair means no waiting for tow trucks or shop availability. We come to you on I-75, Telegraph Road, or wherever you’re stranded with everything needed to diagnose and repair on the spot.
Most breakdowns that leave you calling for help get resolved right there on the roadside. Engine won’t start, brake issues, tire problems—we handle it where you sit. When you can’t afford to lose a day of revenue waiting in some shop’s queue, that’s the difference that matters.
No surprises on pricing either. You get an estimate upfront, and that’s what you pay. Fair rates whether it’s 2 PM or 2 AM, weekday or weekend.
We’ve been Detroit’s go-to semi repair since 1999. What sets us apart isn’t just the decades of experience—it’s Dr. Phillip Marin’s three Ph.D. degrees in Diesel Engineering, Drivetrains, and Metal Alloys. You’re not getting some general mechanic guessing at your problem.
Our ASE-certified technicians know the I-75 corridor inside and out. We’ve pulled trucks out of trouble from Gibraltar Road to West Road, and everywhere in between. Flat Rock drivers know they can count on us because we’ve been here through every kind of breakdown, every weather condition, every emergency you can imagine.
When you’re hauling freight through Michigan’s busiest highway system, you need people who understand what’s at stake. That’s what 40+ years in this business teaches you.
Call 313-999-3088 and you’ll reach our dispatch immediately—24/7, no answering service runaround. We get your exact location, what’s happening with your truck, and dispatch the closest mobile unit. Most of the time, that means help arrives in minutes, not hours.
Our technician shows up with a fully equipped service truck. We’re talking diagnostic equipment, common parts inventory, welding capability, air tools—whatever it takes to get the job done on-site. First step is always a thorough diagnosis so you know exactly what you’re dealing with and what it’s going to cost.
If we can fix it roadside, we fix it roadside. If it needs shop work or major parts, we’ll get you safely towed to where the repair can happen properly. Either way, you’re not sitting around wondering what’s next. You get straight answers and a clear path forward.

We handle everything that can go wrong with a semi truck on Michigan roads. Diesel engine diagnostics and repairs, including injector problems, turbo issues, and computer codes. Brake service covers everything from standard maintenance to ABS sensor repairs and air brake system fixes. Transmission and drivetrain work when you’re losing power or hearing grinding noises.
Flat Rock’s location on the I-75 freight corridor means we see every kind of breakdown scenario. Reefer trailer repairs for temperature-controlled loads that can’t wait. On-site tire replacement when you’ve got a blowout and need to keep rolling. Mobile welding for cracked frames or broken brackets that happen from road conditions and heavy loads.
Our service area covers all the major truck routes—I-75, I-94, Telegraph Road, and the industrial areas where trucks load and unload. We stock parts for the most common repairs because waiting days for parts isn’t an option when you’re trying to make a living hauling freight.
We typically arrive within minutes of your call, especially along the I-75 corridor where most breakdowns happen. Our mobile units are strategically positioned to cover the high-traffic areas around Flat Rock, Telegraph Road, and the major truck stops.
Response time depends on your exact location and current traffic conditions, but we’ve built our reputation on being the fastest reliable service in the Detroit area. When you call 313-999-3088, our dispatcher immediately locates the nearest available technician and gives you an accurate arrival time. No vague “we’ll be there when we can” promises.
No extra charges for nights, weekends, or holidays. Our rates stay the same whether you call at 2 PM on Tuesday or 2 AM on Sunday. Too many companies hit you with “emergency fees” when you’re already dealing with an expensive breakdown.
We quote you a price upfront based on the actual work needed, not when you happen to need it done. Truck breakdowns don’t follow a 9-to-5 schedule, and neither do we. Fair pricing around the clock is just part of doing business right.
Most common breakdowns get fixed right where your truck sits. Engine diagnostics and many engine repairs, brake adjustments and air system fixes, electrical problems, alternator and battery replacement, tire changes, and mobile welding for structural repairs.
Our service trucks carry diagnostic computers, air tools, welding equipment, and an inventory of the most common parts. We can handle injector problems, turbo issues, brake chamber replacements, ABS sensor repairs, and pretty much anything that doesn’t require major disassembly. If it needs shop work, we’ll tell you upfront and arrange proper towing.
Our team is ASE-certified and led by Dr. Phillip Marin, who holds Ph.D. degrees in Diesel Engineering, Drivetrains, and Metal Alloys. We work on all major brands—Freightliner, Peterbilt, Kenworth, International, Volvo, Mack, and others.
The diagnostic equipment we carry works with all the major engine manufacturers: Cummins, Detroit Diesel, Caterpillar, Paccar, and Mercedes. Whether you’re running a newer truck with complex computer systems or an older model that needs old-school mechanical know-how, we’ve got the experience and tools to handle it properly.
We cover the entire I-75 corridor from Detroit down to the Ohio border, plus all the connecting highways like I-94, I-275, I-696, and Telegraph Road. Flat Rock is right in the center of our primary service area, so we’re never far away.
Our coverage includes all of Wayne County and extends into the surrounding areas where trucks commonly travel. Industrial areas, truck stops, weigh stations, and anywhere freight moves through southeastern Michigan. If you’re hauling loads through this region, you’re in our service territory.
Yes, we service both Thermo-King and Carrier refrigeration units. Reefer breakdowns are especially critical when you’re hauling temperature-sensitive freight that can spoil or be damaged if the cooling system fails.
We understand that reefer problems often can’t wait for regular business hours. Whether it’s a compressor issue, electrical problem, or refrigerant leak, we have the equipment and expertise to diagnose and repair refrigeration systems on-site when possible. For major component replacements, we’ll get your trailer to our shop or coordinate with a facility that can handle the repair quickly.
