Hear from Our Customers
Your truck breaks down on I-75 at 2 AM. Most shops make you wait until morning, then charge you for an expensive tow on top of the repair bill. That’s hours of lost revenue you’ll never get back.
We come to you. Our mobile repair units are equipped to handle everything from diesel engine diagnostics to brake repairs right where you’re stranded. You get back to hauling freight instead of sitting in a shop waiting room watching your daily earnings disappear.
When you’re an owner-operator or fleet manager, every hour of downtime hits your bottom line hard. We understand that, because we’ve been keeping Michigan truckers moving for over 40 years.
We’ve been serving Michigan’s trucking industry since the 1980s. We’re not some fly-by-night operation that learned diesel repair from YouTube videos.
Dr. Phillip Marin leads our team with three Ph.D. degrees in Diesel Engineering, Drivetrains, and Metal Alloys. That level of technical expertise means we diagnose problems correctly the first time and fix them right, so you’re not dealing with the same issue again next month.
We’re positioned right in the heart of Michigan’s busiest freight corridor. I-75 carries over 15,000 trucks daily through this area, and we know every common breakdown that happens on this route. When other shops are guessing, we already know what’s wrong and how to fix it.
Call us when your truck goes down. We dispatch immediately with a fully equipped mobile unit that can handle most repairs on the spot. No waiting for a tow truck, no sitting in a shop for days.
Our technician arrives with professional diagnostic equipment and a truck full of common parts. We run a complete diagnosis to identify the root problem, not just the symptoms. Then we explain exactly what needs to be fixed and give you a straight price before we start any work.
Most roadside repairs are completed within a few hours. For complex issues that require shop work, we can often get you mobile enough to reach our facility under your own power, saving you hundreds in towing fees. We handle all the paperwork and can work directly with your fleet management if needed.

We handle everything from simple tire changes to complex engine rebuilds. Diesel engine diagnostics, brake system repairs, electrical troubleshooting, hydraulic issues, air system leaks, transmission problems, and reefer unit service.
Michigan’s harsh winters and heavy freight loads put extra stress on trucks running the I-75 corridor. We see a lot of brake issues from the constant stopping and starting in Detroit traffic, air system problems from temperature swings, and electrical gremlins from road salt corrosion.
Our mobile units carry parts for the most common repairs on Freightliner, Peterbilt, Kenworth, Volvo, and Mack trucks. For specialized components, we have relationships with parts suppliers throughout southeast Michigan and can usually get what we need within hours, not days.
Mobile repair typically costs about the same as shop labor rates, but you save significantly on towing and downtime expenses. Most towing for a semi runs $300-$1,500 depending on distance and complexity.
The real savings come from avoiding downtime. Every day your truck sits in a shop costs you $1,000-$2,000 in lost revenue. Mobile repair gets you back on the road the same day for most common problems, which more than makes up for any difference in hourly rates.
We’re transparent about pricing upfront. You’ll know exactly what the repair will cost before we start work, with no surprise charges or hidden fees.
Our mobile units can handle about 85% of roadside breakdowns without needing to tow your truck. This includes diesel engine diagnostics, brake adjustments and repairs, electrical system troubleshooting, air system leaks, hydraulic problems, starter and alternator replacement, and most transmission issues.
We carry diagnostic computers that can read fault codes on all major truck brands. Our trucks are stocked with common wear items like belts, hoses, filters, fuses, and basic electrical components. For tire issues, we can handle everything from simple repairs to complete tire and wheel replacement.
The only repairs we can’t do on-site are major engine rebuilds, transmission overhauls, or work requiring specialized shop equipment like frame straightening. Even then, we can often get your truck mobile enough to reach our shop under its own power.
Yes, we provide true 24/7 emergency service, 365 days a year. Freight doesn’t stop for weekends or holidays, and neither do we. When you call our emergency line, you reach a real person who can dispatch a technician immediately.
Response times depend on your location and our current call volume, but we typically reach breakdowns on major highways like I-75 within 45-90 minutes. For urgent situations involving safety hazards or blocking traffic, we prioritize those calls and can often respond faster.
Our emergency service covers all of southeast Michigan, including the I-75 corridor from Toledo to Flint, I-94 from Kalamazoo to Detroit, and all connecting highways. We know this area’s truck routes and can find you quickly even if you’re not sure exactly where you are.
We service all major semi truck brands including Freightliner, Peterbilt, Kenworth, Volvo, Mack, International, and Western Star. Dr. Marin’s advanced engineering background means we understand the technical differences between manufacturers and can adapt our diagnostic approach accordingly.
Our diagnostic equipment is updated regularly to handle the latest electronic systems on newer trucks, but we also have the experience to work on older mechanical systems. Whether you’re running a 2024 Cascadia or a 1995 Classic XL, we have the knowledge and tools to get it fixed.
For specialized equipment like reefer units, we work on Carrier, Thermo King, and other major brands. We keep up with training on new technologies as we introduce them, so we’re always current on the latest systems.
For breakdowns on I-75 between Toledo and Flint, we typically respond within 45-90 minutes depending on traffic and our current call volume. This corridor is our primary service area, and we know every mile marker and exit.
During peak traffic hours or severe weather, response times may extend to 2 hours, but we keep you updated on our estimated arrival time. We also coordinate with Michigan State Police when necessary for safe positioning of our service vehicles on busy highways.
If you’re broken down in a dangerous location, we work with law enforcement to get traffic control in place before our technician arrives. Safety is our top priority, both for our crew and for other drivers sharing the road.
Yes, we provide comprehensive fleet maintenance programs for trucking companies operating in southeast Michigan. These contracts include scheduled preventive maintenance, priority emergency response, and discounted labor rates for your drivers.
Fleet contracts help you budget maintenance costs more predictably and reduce unexpected breakdowns through regular inspections and service. We can customize programs based on your fleet size, typical routes, and specific equipment needs.
Our fleet customers get priority dispatch for emergency calls and direct billing arrangements to simplify paperwork. We also provide detailed maintenance records and reporting to help you track costs per vehicle and identify trucks that may need replacement due to excessive repair expenses.
