Hear from Our Customers
When your semi’s down, you’re losing $400-800 per day in revenue. That’s why we respond within minutes, not hours. Our mobile units roll directly to your location with the parts and expertise to get you moving again.
No more waiting for a tow truck. No more sitting in some shop’s queue for days. You call, we roll, you’re back to making money. It’s that simple.
Our ASE-certified master mechanics handle everything from diesel engine diagnostics to brake repairs right on-site. We stock the parts you need 99% of the time, so there’s no “we’ll have to order that” nonsense when you’re already behind schedule.
We’ve been the go-to emergency repair service in the Detroit metro area for over four decades. We’re not some fly-by-night operation—we’re the family-owned company that Rockwood truckers call when they need real expertise, fast.
Led by Dr. Phillip Marin, who holds three Ph.D.s in Diesel Engineering, Drivetrains, and Metal Alloys, our team understands these machines inside and out. We’ve seen every breakdown scenario you can imagine, and we’ve got the tools and knowledge to handle whatever’s keeping your truck off the road.
We serve the entire I-75 corridor through Rockwood and surrounding Wayne County areas. When other shops are closed, we’re still answering the phone. When other services say “we’ll get there when we can,” we’re already on our way.
First, you call our dispatch at 313-999-3088 and tell us where you are and what’s wrong. We’re answering 24/7, so you’ll reach a real person, not some voicemail system.
Next, we dispatch the closest mobile unit to your location. Our trucks are strategically positioned throughout Wayne County, so we can typically reach you within minutes, not hours. You’ll get a call with our estimated arrival time.
When our technician arrives, we’ll diagnose the problem using state-of-the-art computer diagnostics. Most issues can be identified quickly—we’re not guessing or throwing parts at problems. If it’s something we can fix on-site, we get to work immediately.
Finally, we complete the repair using quality parts from our mobile inventory. You’re back on the road the same day in most cases, with a repair that’s built to last. We accept all major credit cards, so payment is quick and easy.

We handle everything that can go wrong with your semi, from simple battery replacements to complex engine rebuilds. Our mobile units carry diagnostic equipment for all major brands—Freightliner, Peterbilt, Kenworth, Volvo, International, Mack, and more.
Rockwood’s location along the I-75 corridor means heavy traffic and hard stops, which is tough on brake systems. We specialize in air brake repairs, ABS diagnostics, and complete brake overhauls. Our technicians can rebuild brake chambers, replace air lines, and fix those annoying brake warning lights right on the spot.
Engine problems don’t wait for convenient times. Whether it’s a blown turbo, failed injectors, or cooling system issues, we’ve got the expertise and parts to get you running again. We even handle complex emission system repairs and forced regens that leave other shops scratching their heads.
For refrigerated loads, we service Thermo-King and Carrier reefer units. A failed reefer means spoiled cargo and angry customers—we understand the urgency and respond accordingly.
We typically respond within minutes to emergency calls in the Rockwood area. Our mobile units are strategically positioned throughout Wayne County and along the I-75 corridor to ensure fast response times.
Unlike other services that might take hours to reach you, we understand that every minute your truck is down costs you money. Our dispatch system immediately identifies the closest available technician to your location. In most cases, you’ll see our mobile unit arriving within 15-30 minutes of your call, even during peak traffic hours.
We maintain this quick response capability 24/7, 365 days a year. Whether you break down at 2 PM on a Tuesday or 2 AM on a Sunday, our response time commitment remains the same.
Our mobile units are equipped to handle the vast majority of semi truck repairs right where you’re stranded. We perform diesel engine diagnostics, brake system repairs, electrical troubleshooting, air system fixes, starter and alternator replacement, battery service, and cooling system repairs.
We also handle transmission issues, hydraulic problems, tire changes, and even welding repairs. Our technicians carry advanced diagnostic computers that work with all major truck brands—Freightliner, Peterbilt, Kenworth, Volvo, International, Mack, Cummins, Caterpillar, and others.
The only repairs we can’t complete roadside are major overhauls that require lifting the truck or extensive disassembly. For those situations, we’ll tow you to our shop facility where we can complete any repair needed.
Yes, we service all major semi truck and trailer brands. Our diagnostic equipment and parts inventory cover Freightliner, Peterbilt, Kenworth, Volvo, International, Western Star, Mack, Detroit Diesel, Cummins, Caterpillar, Paccar, Navistar, and Ford.
Our lead technician, Dr. Phillip Marin, holds three Ph.D.s in Diesel Engineering, Drivetrains, and Metal Alloys, giving us deep technical knowledge across all manufacturers. We stay current with the latest technology and emission systems, so we can properly diagnose and repair even the newest trucks.
We also service all types of trailers, including dry vans, flatbeds, refrigerated units (reefers), and specialized equipment. Our parts inventory includes components for Thermo-King and Carrier refrigeration units, as well as trailer brake systems, electrical components, and structural repairs.
Our rates remain consistent regardless of when you need service—no premium charges for nights, weekends, or holidays. We believe emergency repairs shouldn’t come with price gouging, especially when you’re already dealing with the stress and cost of unexpected downtime.
We provide upfront pricing before starting any work, so you know exactly what you’re paying. Our diagnostic fee is applied toward the repair cost if you proceed with our service. We accept all major credit cards, cash, checks, and wire transfers for your convenience.
Most roadside repairs cost significantly less than towing to a shop plus repair fees, especially when you factor in the reduced downtime. We’ll give you a clear breakdown of costs and explain your options before proceeding with any work.
Absolutely. We specialize in refrigerated trailer repairs for both Thermo-King and Carrier units. When your reefer goes down with a load of perishables, every minute counts—we understand the urgency and respond accordingly.
Our technicians can diagnose and repair compressor issues, electrical problems, refrigerant leaks, and control system failures. We carry common refrigeration parts and refrigerant in our mobile units, so many reefer problems can be fixed on the spot without requiring a trip to a specialized shop.
We also handle trailer electrical issues, door problems, and structural repairs that might affect the refrigeration unit’s performance. If the repair requires specialized equipment we don’t carry, we can arrange temporary refrigeration solutions to protect your cargo while we complete the permanent fix.
Yes, we work with fleets of all sizes throughout the Rockwood and Wayne County area. We understand that fleet managers need reliable partners who can minimize downtime and control maintenance costs across multiple vehicles.
We offer scheduled mobile maintenance services, emergency repair response, and preventive maintenance programs tailored to your fleet’s needs. Our technicians can perform DOT inspections, oil changes, brake adjustments, and other routine maintenance at your facility or wherever your trucks are located.
Fleet customers receive priority response and special pricing arrangements. We can also provide detailed maintenance records and reporting to help you track vehicle performance and plan future maintenance needs. Our goal is to keep your entire fleet running efficiently while reducing your total cost of ownership.
