Hear from Our Customers
When your semi breaks down, every minute costs money. You’re not just dealing with repair bills – you’re watching delivery deadlines slip away and customers get frustrated. That’s why we built our entire operation around getting to you fast and getting the job done right the first time.
Our mobile repair trucks arrive equipped with everything needed for most repairs. We diagnose the problem quickly, give you an honest assessment, and get to work immediately. No waiting for tow trucks, no sitting in shop queues for days, no wondering when you’ll be back on the road.
Most repairs get completed on-site within hours, not days. When we can’t fix it roadside, we have the shop capacity and parts inventory to handle the bigger jobs without the typical delays you’ve experienced elsewhere.
We operate as J&J Truck & Trailer Repair, and we’ve been the go-to solution for truckers in the Detroit metro area for over four decades. This is a family-owned operation that understands what it means when your livelihood depends on keeping that truck moving.
Dr. Phillip Marin leads our team with three PhD degrees in Diesel Engineering, Drivetrains, and Metal Alloys. That level of expertise means we don’t just fix what’s broken – we understand why it broke and how to prevent it from happening again. Our ASE certified master mechanics bring that same depth of knowledge to every call.
Operating out of Detroit, we know the unique challenges that come with running trucks through Michigan’s harsh winters and heavy traffic corridors like I-75, I-94, and I-96. We’ve seen every type of breakdown scenario and have the experience to handle whatever situation you’re facing.
When you call, our dispatch immediately sends the nearest mobile repair unit to your location. Response times are typically within minutes in the Grosse Pointe area, and we maintain the same fast response whether it’s 2 PM or 2 AM.
The technician arrives with a fully equipped service truck – diagnostic equipment, welders, compressors, and an inventory of the most commonly needed parts. We perform a thorough diagnostic assessment and explain exactly what’s wrong, what it will cost, and how long it will take.
Most repairs happen right there on the spot. If it’s something that requires shop facilities, we have the equipment to safely transport your truck and the shop capacity to prioritize your repair. Throughout the process, you get regular updates so you can plan accordingly and keep your customers informed.

Our service range covers everything from emergency roadside fixes to complex engine overhauls. Brake system repairs, electrical diagnostics, transmission work, and air system problems – we handle the full spectrum of semi truck issues that keep drivers sidelined.
For reefer units, we’re certified on both Thermo-King and Carrier systems, which is crucial for drivers hauling temperature-sensitive cargo through the Detroit area’s busy freight corridors. We also stock drive shafts, transmissions, engines, tires, and rims to minimize parts delays.
Our Grosse Pointe location puts us in the heart of one of Michigan’s busiest transportation zones. We’re strategically positioned to serve the I-94 corridor that connects Detroit to Chicago, as well as the I-75 route that handles massive freight volumes between Canada and the southern United States. This location advantage means faster response times when you’re broken down on these critical routes.
Response times are typically within minutes for the Grosse Pointe area. We maintain mobile repair units strategically positioned throughout the Detroit metro region, so there’s usually a technician relatively close to your location.
The exact response time depends on your specific location and current traffic conditions, but our dispatch system is designed to get help to you as quickly as possible. We understand that every minute your truck sits idle costs you money, so speed is built into our entire operation.
Unlike national services that might take hours to reach you, we’re a local operation that knows the area and maintains the resources needed for truly rapid response.
Our mobile units handle most common breakdowns right at your location – brake repairs, electrical problems, air system leaks, battery replacements, alternator issues, and many engine diagnostics and repairs. Each truck carries welding equipment, diagnostic computers, and an inventory of frequently needed parts.
More complex work like major engine overhauls, transmission rebuilds, or extensive bodywork typically requires shop facilities. However, we have a full-service shop in Detroit with the capacity to handle these larger jobs without the typical delays you’d experience at other facilities.
Our technician will assess your situation and let you know immediately whether it’s something we can fix on-site or if it needs to come to the shop. Either way, we have the resources and expertise to get you back on the road efficiently.
No. Our rates remain the same regardless of when you call – nights, weekends, holidays, it doesn’t matter. This is unusual in the industry, where many services tack on significant surcharges for off-hours calls.
We believe that truck emergencies don’t follow business hours, and drivers shouldn’t be penalized with higher costs just because their breakdown happened at an inconvenient time. You get the same competitive rates and quality service whether you call at noon on Tuesday or midnight on Saturday.
This consistent pricing policy is part of our commitment to treating drivers fairly during what’s already a stressful and expensive situation.
Dr. Phillip Marin’s three PhD degrees in Diesel Engineering, Drivetrains, and Metal Alloys bring an unusual level of technical expertise to our diagnostic process. This isn’t just about reading codes – it’s about understanding the underlying engineering principles that explain why problems occur.
Our mobile units carry state-of-the-art computer diagnostic equipment that can interface with all major truck and engine manufacturers’ systems. We can perform forced regens, diagnose ABS issues, and troubleshoot complex electrical problems right at your location.
The combination of advanced equipment and deep technical knowledge means we often identify root causes that other services miss. This leads to more permanent fixes and fewer repeat problems, which saves you money and downtime in the long run.
Yes, we’re certified to work on both Thermo-King and Carrier refrigeration systems, which covers the vast majority of reefer units on the road. This is critical capability for drivers hauling food, pharmaceuticals, or other temperature-sensitive cargo through the Detroit area.
Reefer breakdowns are particularly urgent because your load can be compromised within hours if the temperature control fails. Our technicians understand this urgency and prioritize these calls accordingly. We stock common reefer parts and have the diagnostic equipment needed to troubleshoot these complex systems.
Whether it’s a compressor issue, electrical problem, or refrigerant leak, we have the expertise and equipment to get your reefer unit back to proper operating temperature quickly, protecting your cargo and your customer relationships.
We provide mobile repair services throughout the entire Detroit metro area, including all of Wayne County and surrounding regions. This covers the major freight corridors like I-94, I-75, I-96, I-275, and I-696, as well as US-24 and Telegraph Road.
Our service area extends well beyond just Grosse Pointe to include Detroit, Warren, Sterling Heights, Dearborn, and the broader southeastern Michigan region. Basically, if you’re broken down anywhere in the Detroit metro area’s trucking corridors, we can reach you.
The key advantage of our local focus is that we know these routes intimately – the traffic patterns, the common breakdown spots, and the fastest ways to reach stranded drivers. This local knowledge translates into faster response times and more efficient service than you’d get from national chains.
