On-Site Truck Repair That Keeps Your Load Moving

Every hour a truck sits on the shoulder costs money: a missed appointment, an unhappy broker, a driver burning hours of service. A heavy-duty tow can run hundreds of dollars and hours of waiting before anyone even looks at the problem.

Steelcore Truck Repair skips all of that. Our mobile truck repair service comes to wherever your truck is — the shoulder of I-85, a truck stop, a customer’s dock or your own yard. We diagnose the problem with a professional scan tool, fix it on the spot and get you rolling again.

We handle semi truck repair for tractors, day cabs and heavy-duty diesel trucks across Charlotte and up to 200 miles out in North and South Carolina. Owner-operator, dispatcher or fleet manager — it works the same way: one call, and a mobile diesel mechanic is on the way.

Mobile Truck Repair Services

Most breakdowns that stop a truck can be fixed right where it’s parked. Here’s what we handle on-site:

Engine Diagnostics & Repair

Check engine light, no-start or loss of power? We read fault codes with a professional scan tool, find the real cause and handle minor engine and fuel system repairs on the spot.

  • Computer diagnostics
  • Fault code scanning
  • No-start diagnostics
  • Minor engine repairs
  • Diesel fuel system diagnostics

DPF, DEF & Aftertreatment

Truck in derate? We diagnose DPF and DEF faults and run a forced regen on-site when the system allows it. If the filter needs more than a regen, we'll tell you straight.

  • DPF diagnostics
  • Forced DPF regeneration
  • DEF system diagnostics
  • Aftertreatment troubleshooting

Electrical & Batteries

Dead batteries, a bad starter or lights out right before an inspection — we track down the fault and fix it.

Put out of service at a roadside inspection? We can often fix common out-of-service items — lights, air leaks, brake adjustment — right where you’re parked.

Trailer acting up too? We also handle mobile trailer repair — one call for both.

Planning ahead? Keep your trucks on schedule with mobile truck maintenance and PM at your yard.

How It Works

  1. Call or Text

    Tell us where the truck is — exit, mile marker or address — plus the unit number and what's going on. A photo of the dash lights or the problem helps.

  2. We Roll Out

    A mobile truck mechanic heads your way with the tools and parts for the job. You get a real ETA on the phone, not a guess.

  3. Fixed and Rolling

    We find the cause, explain what the truck needs and what it will cost, make the repair and get you back on the road.
