Mobile Truck & Trailer Repair
Mobile Truck & Trailer Repair Across the Midwest
A truck down on the side of the road isn't a repair bill. It's a missed load, a stuck driver, and a customer who's done waiting. Heartland Fleet brings the repair shop to you — at your yard or on the shoulder — so your truck gets fixed where it sits instead of riding a tow truck across town.
We come to you. Serving the Midwest, including Kansas City, Omaha, St. Louis, & Denver.
Our mobile diesel mechanics show up with the diagnostic tools and parts to handle most breakdowns on the first visit — semi trucks, straight trucks, and trailers alike.

Truck & Trailer Services
Our trucks are rolling repair shops. We diagnose and repair every major system on commercial vehicles — most of it right there in your yard or at the breakdown, no towing required.
Diesel Engine Repair & Drivetrain Service
Engine diagnostics, no-starts, overheating, coolant and oil leaks, turbo and fuel-system issues, and drivetrain work — clutches, transmissions, driveshafts, and differentials. We service all makes and models — Freightliner, Kenworth, Peterbilt, International, Mack, Volvo, and more.
Brake Repair & ABS Service
Air brake repair, slack adjusters, chambers, lines, and leaks, plus ABS faults. Brake problems are the number-one item that sidelines a truck at a DOT stop — we fix them right and document the work.
Truck Electrical Repair & Computer Diagnostics
Charging and starting systems, alternators, batteries, lighting, sensors, and wiring faults. Our techs carry dealer-grade diagnostic scanners to read fault codes on the spot instead of guessing.
DPF, DEF & EGR Repair (Emissions & Aftertreatment)
Aftertreatment problems trigger derates and kill fuel economy. We service DPF, DEF, and EGR systems, handle forced regens, and clear the faults that put your truck in limp mode.
Suspension, Steering & Truck A/C Repair
Suspension, steering, and front-end work, wheel-end and bearing service, and cab A/C and heating repair — so your drivers stay safe and comfortable through every season.
Semi-Trailer Repair (Brakes, Lights, Doors & More)
Trailers break down as often as the trucks pulling them. We handle trailer brakes and air lines, lights and wiring, landing gear, doors and hinges, floor and structural repairs, and tandem and suspension work — on dry vans, reefers, flatbeds, and tankers.
Not sure what's wrong? Tell us the symptoms and we'll dispatch a mobile diesel mechanic who can diagnose it on site. Call (877) 453-5338.
We Come To You
Most of our repair work happens at your terminal, warehouse, or yard, on a schedule that fits your operation. But breakdowns don't wait for business hours, so neither do we.
Done Right
Anyone can patch a truck and send it down the road. We fix the cause, document the work, and feed it back into your maintenance records — so the same failure doesn't strand you again next month.
Find the cause, not just the symptom.
Every repair follows a complaint-cause-correction process: what failed, why it failed, and exactly what we did to fix it.
Documented and audit-ready.
We log repairs with industry-standard VMRS codes, so every truck has a clean service history for warranty claims, cost tracking, and DOT compliance.
One provider, one record.
Reactive repairs roll into the same system as your preventive maintenance — so one team knows the full history of every unit.
That last point is the real difference. A one-off roadside fix gets you moving today. Pairing it with a preventive maintenance program keeps you from making the call in the first place.
Trucks & Trailers We Service
We repair commercial vehicles across the medium- and heavy-duty range — Class 3 through Class 8 — plus the trailers behind them.
Medium duty (Class 3–6):
Box trucks, step/walk-in vans, city delivery trucks, and bucket/utility trucks.
Heavy duty (Class 7–8):
Semi tractors (day cabs and sleepers), dump trucks, refuse trucks, and other big rigs.
Trailers:
Trailers: dry vans, reefers, flatbeds, and tankers.
