Hear from Our Customers
Every minute your truck sits broken down costs you money. At $450-760 per day in lost revenue, you can’t afford to wait for help that might not come for hours.
That’s where we step in. Our mobile repair units reach you faster than traditional towing services, often fixing problems right where you broke down. No expensive tow bills. No waiting at unfamiliar shops. Just expert diagnostics and repairs that get you moving again.
When your diesel engine throws codes at 2 AM on I-75, or your brakes start acting up near the La Salle exit, you need someone who understands what’s at stake. Your delivery schedule. Your customer relationships. Your bottom line.
We’ve been the go-to emergency service for truckers navigating the I-75 corridor since 1999. We’re not just another repair shop – we’re the family-owned business that understands what it means when your livelihood depends on keeping those wheels turning.
Dr. Phillip Marin leads our team with three Ph.D. degrees in Diesel Engineering, Drivetrains, and Metal Alloys. That level of expertise doesn’t just sound impressive – it translates to faster, more accurate diagnoses when you’re stranded.
South Rockwood sits right in the heart of Michigan’s freight corridor, where thousands of trucks pass through daily carrying everything from auto parts to agricultural products. We’ve built our reputation one emergency call at a time, serving everyone from independent owner-operators to major fleet managers who know they can count on us when things go wrong.
When you call us with a breakdown, our dispatch immediately sends the nearest mobile unit to your location. We’re not making you wait while we “see who’s available” – we know every minute counts.
Our technician arrives with a fully-equipped service truck containing diagnostic equipment, common parts, and tools needed for most roadside repairs. First, we run a complete diagnostic to identify exactly what’s wrong. No guessing. No unnecessary work.
If it’s something we can fix on-site – and most problems are – we handle it right there. Engine codes, brake issues, electrical problems, cooling system failures, and tire emergencies typically get resolved without needing a tow truck. For major repairs requiring shop work, we coordinate the tow and can often recommend trusted facilities along your route.
You get a clear explanation of what happened, what we fixed, and what to watch for going forward. Our goal isn’t just getting you moving again – it’s making sure you understand your truck well enough to prevent similar problems.

Our mobile semi truck repair covers everything from diagnostic troubleshooting to emergency welding. Diesel engine problems, transmission issues, brake system failures, electrical shorts, cooling system leaks, and hydraulic repairs – we handle what breaks down most often on trucks working the I-75 corridor.
South Rockwood’s location puts us within quick reach of major freight routes where trucks face unique challenges. The constant stop-and-go traffic near Detroit puts extra stress on brake systems. Temperature extremes affect cooling systems and battery performance. Heavy loads strain transmissions and differentials.
We stock our mobile units based on the most common problems we see in this area. ABS sensors, air brake components, cooling system parts, belts, hoses, and electrical components that frequently fail on trucks running these routes. That means faster repairs and less downtime waiting for parts to arrive.
For reefer units hauling temperature-sensitive cargo, we understand the urgency. When your refrigeration system fails, every hour counts before your load gets compromised. Our technicians have specific training on major reefer brands and carry common components for quick fixes.
Our average response time to the South Rockwood area is typically 30-45 minutes, depending on your exact location and current traffic conditions on I-75. We maintain mobile units strategically positioned to serve the major freight corridors, so we’re not starting from scratch when you call.
During peak traffic hours or severe weather, response times may extend slightly, but we always dispatch the nearest available technician immediately. Our dispatch system tracks all units in real-time, so we can give you an accurate arrival estimate when you call.
For locations right off I-75 near the La Salle exit or Telegraph Road, we can often arrive even faster since these are high-traffic areas we serve regularly.
About 70% of the breakdowns we respond to get resolved right at your location. This includes diagnostic trouble code clearing, brake adjustments and component replacement, electrical system repairs, cooling system leak repairs, belt and hose replacement, battery and alternator issues, and most tire-related problems.
Our mobile units carry extensive parts inventory for common failures we see on trucks running I-75. We can handle fuel system problems, air brake issues, basic transmission repairs, and emergency welding for structural problems.
Major engine rebuilds, transmission overhauls, differential work, and complex electrical rewiring typically require shop facilities. In those cases, we coordinate with trusted repair facilities and can often recommend shops along your planned route to minimize disruption to your schedule.
Yes, our technicians are trained to work on all major truck manufacturers including Freightliner, Peterbilt, Kenworth, Volvo, Mack, International, and others. Dr. Marin’s advanced engineering background gives our team deep understanding of different engine platforms, transmission systems, and electrical architectures across manufacturers.
We also service all types of trailers including dry vans, flatbeds, reefer units, and specialized equipment. Our diagnostic equipment works with most modern truck computer systems, and we maintain updated software for the latest model years.
For older trucks, we have the experience and reference materials needed to troubleshoot systems that might not have computerized diagnostics. Many owner-operators run older equipment, and we understand these trucks often require different approaches than newer models.
Our service call fee covers the technician dispatch, initial diagnostics, and first hour of labor. Additional labor is charged in 15-minute increments at our standard rate. Parts are billed at cost plus a reasonable markup – we’re not trying to make our profit on emergency parts pricing.
We accept most major fleet fuel cards including Comdata, EFS, and T-Chek, which makes billing easier for company drivers and fleet operators. Cash, credit cards, and direct billing arrangements are also available.
Before starting any work beyond basic diagnostics, we provide a clear estimate of expected costs. If the repair exceeds our initial estimate, we contact you before proceeding. No surprise bills or hidden charges – you’ll know what you’re paying before we do the work.
Absolutely. When your truck gets pulled into a DOT inspection and violations are found, we can often perform the necessary repairs on-site to get you back in compliance quickly. Common inspection failures we handle include brake adjustments, lighting repairs, tire issues, and minor mechanical problems.
Our technicians understand DOT requirements and can advise you on whether a repair will satisfy inspection standards. We carry DOT-compliant parts and know the specifications inspectors look for.
If you’re dealing with an out-of-service order, we can coordinate with the inspection station to verify repairs meet requirements for getting your truck released. Time is critical in these situations, and we work efficiently to minimize the impact on your schedule and avoid additional penalties.
Yes, reefer repair is one of our specialties because we understand how critical temperature control is for your cargo. When a refrigeration unit fails, you’re often racing against time before your load gets compromised and you face major financial losses.
We service all major reefer brands including Carrier, Thermo King, and others. Common problems we handle include compressor issues, electrical faults, refrigerant leaks, and control system failures. Our mobile units carry common reefer parts and refrigerant for on-site repairs.
For complex reefer problems requiring specialized parts or major component replacement, we work with certified reefer shops and can coordinate emergency service to minimize temperature exposure time. We understand the urgency of these situations and prioritize reefer calls accordingly.
