Hear from Our Customers
Your delivery schedule doesn’t stop for breakdowns. Neither do we. Our mobile repair trucks carry the parts and diagnostic equipment to fix most issues right where you’re stranded.
You’re not paying for a tow plus shop time plus markup. You’re getting the repair done on-site, at a fair price, so you can get back to making money instead of losing it on the shoulder.
When we’re done, you drive away. No waiting for tow trucks, no sitting in some shop’s queue, no wondering if they actually know diesel engines. Just professional repair work that gets you moving.
J&J Truck & Trailer Repair has been handling roadside emergencies in Michigan since the early 1980s. We’re the family-owned company that Detroit-area truckers call when they need someone who actually shows up.
Dr. Phillip Marin leads our team with three Ph.D. degrees in Diesel Engineering, Drivetrains, and Metal Alloys. That’s not just impressive credentials – it’s the kind of deep knowledge that means we diagnose problems correctly the first time.
Our ASE certified mechanics know the difference between a quick fix and a lasting repair. We’ve seen every breakdown scenario on Michigan roads, from I-75 to the back roads around Erie.
You call us with your location and problem. We dispatch immediately – usually within minutes, not hours. Our mobile unit arrives with diagnostic equipment and a comprehensive parts inventory.
We run diagnostics to identify the exact issue, not just symptoms. Then we give you a clear estimate before starting any work. No surprise charges, no “while we’re at it” upsells.
Most repairs happen on-site. If we need specialized equipment or parts we don’t carry, we’ll get you safely towed to our shop or another facility. Either way, you know exactly what’s happening and what it costs.

We handle everything from emergency brake repairs to complete engine diagnostics. Our mobile units carry parts for the most common failures – alternators, belts, hoses, brake components, and electrical issues.
Erie sits right on major trucking routes, which means breakdowns happen at all hours. We provide 24/7 service because a Tuesday afternoon breakdown costs just as much as a Saturday night emergency.
Our service area covers I-75, US-24, and the surrounding Monroe County roads. Whether you’re hauling through Erie or making local deliveries, we know these routes and can reach you quickly.
We typically respond within 45-60 minutes for the Erie area, often faster depending on our current location and traffic conditions. Our dispatch system tracks our mobile units in real-time, so we send the closest available truck to your location.
Unlike some services that give you a 2-4 hour window, we provide specific arrival times and keep you updated if anything changes. When you’re losing money sitting on the shoulder, every minute counts.
We maintain our fast response times by keeping mobile units strategically positioned throughout Southeast Michigan and by operating 24/7 – no reduced hours or weekend delays.
Our mobile units handle most common roadside repairs including brake adjustments, ABS sensor replacement, alternator and battery service, belt and hose repairs, and basic engine diagnostics. We also provide tire changes, jump starts, and emergency fuel delivery.
For more complex issues like transmission problems or major engine work, we’ll diagnose the problem on-site and arrange safe transport to an appropriate repair facility. We carry diagnostic equipment that can read fault codes and identify issues that other roadside services might miss.
Each mobile unit stocks parts for the most frequent breakdown scenarios, so there’s a good chance we can complete your repair without a trip to the shop.
Yes, we service all major semi truck brands including Freightliner, Peterbilt, Kenworth, International, Volvo, Mack, and Western Star. Our diagnostic equipment works with Detroit Diesel, Cummins, Caterpillar, and other engine manufacturers.
Dr. Marin’s specialized education in diesel engineering means we understand the systems across different manufacturers, not just one brand. This is especially important for owner-operators who might have older trucks or mixed fleets.
We also handle trailer repairs including reefer units (Thermo-King and Carrier), electrical systems, and brake components for all standard trailer types.
Our rates are the same whether you call at 2 PM or 2 AM – no premium charges for nights, weekends, or holidays. We provide upfront estimates before starting work, so you know exactly what the repair will cost.
Most emergency service calls include a diagnostic fee that covers our response time and initial assessment. If you approve the repair, this fee is applied to your total bill. We accept cash, credit cards, and most fleet payment methods.
We believe emergency situations are stressful enough without worrying about inflated pricing. Our goal is fair, transparent pricing that lets you make informed decisions about your repair.
Absolutely. We perform DOT inspections and handle the repairs needed to get you back in compliance. Common issues include brake adjustments, lighting problems, and minor safety violations that can be fixed on-site.
If you’ve been placed out of service during a roadside inspection, we can often get you legal to drive again without a trip to the shop. We understand DOT regulations and know which repairs are required versus recommended.
Our mobile units carry the most common DOT-related parts including lights, reflectors, and basic brake components. We can also arrange towing if major repairs are needed to pass inspection.
Yes, we work with both individual owner-operators and fleet customers throughout the Detroit metro area. Fleet customers appreciate our consistent response times and transparent pricing – no surprises on the invoice.
We can set up fleet accounts with preferred payment terms and provide regular service reports. For larger fleets, we can also arrange preventive maintenance visits to reduce roadside breakdowns.
Our experience with fleet operations means we understand the importance of keeping trucks moving and minimizing downtime. We work with your dispatch and maintenance teams to coordinate service efficiently.
