Mobile Service · Rock Hill, SC & the Carolinas
When your commercial truck breaks down on the road or at a job site, the last thing you need is a long wait for a tow truck. Interstate Fleet Services dispatches experienced diesel technicians directly to your location — on the highway, at a distribution dock, on a job site, or wherever you're stuck. We come to you, assess the problem on-site, and fix it there if at all possible. Our goal is to get you back rolling without ever needing a tow.
DEF system faults, sensor failures, clogged injectors, and SCR system errors that put your truck into limp mode. We carry DEF components and can often restore full power roadside without a tow to a dealership.
Leaking air lines, failed brake chambers, bad glad hands, cracked airline fittings, air dryer failures, and air system pressure problems. We diagnose and repair air brake systems on-site with proper equipment.
Fuel filter blockages, fuel pump failures, fuel line leaks, and injector problems. If your engine is losing power, running rough, or won't start, we diagnose the fuel system on-site.
Alternator failures, battery issues, wiring harness problems, trailer lighting faults, ABS sensor failures, ECM communication errors, and more. We bring scan tools for all major platforms.
Thermostat failures, radiator hose blowouts, water pump failures, coolant leaks, and overheating issues. We carry common cooling system components for many truck makes and models.
Commercial truck tire changes, flat repairs, valve stem replacements, and tire mounting. We carry tire inventory for road service calls and can handle most commercial tire emergencies.
Dead battery? We provide heavy-duty commercial truck jump starts and can replace batteries on-site for most truck makes. One call and we come to you.
Blown hydraulic hoses on dump trucks, construction equipment, and hydraulic systems. We fabricate and replace hoses on-site — no need to transport your equipment.
Tow Bill
If we can fix it on-site, you avoid a costly tow. We fix most breakdown issues roadside.

Experience
26 years of diesel experience means our techs diagnose fast and fix it right the first time.
Every hour your truck sits idle costs you money — in lost revenue, in late deliveries, in frustrated customers. Mobile diesel repair minimizes that downtime by bringing the solution directly to the problem. Our technicians arrive equipped with the diagnostic tools, parts inventory, and experience to handle the most common breakdown scenarios on-site. For the Rock Hill, SC area and all surrounding routes, Interstate Fleet Services is the fastest qualified mobile diesel repair option available.
We service all major truck brands: Peterbilt, Kenworth, Freightliner, International, Mack, Volvo, Western Star, and more. Older mechanical trucks and fully electronic modern platforms — we have the equipment for both. When we say we'll fix it, we mean it.
We handle a wide range of on-site repairs: DEF system repairs, air brake system work, electrical diagnostics and repairs, fuel system issues, tire changes, jump starts, hydraulic hose replacement, cooling system repairs, and minor engine work. If it's safe to perform on-site, we'll do it there.
We dispatch throughout York County, Chester County, Lancaster County, Mecklenburg County, and the surrounding areas. We cover I-77 from Rock Hill to Charlotte, I-85 near Kings Mountain, US-521, and all surrounding routes. Call us and we'll confirm coverage for your location.
There's typically a travel/dispatch charge for mobile calls, but you often save money because you avoid the tow bill and the labor costs are the same as in-shop. For many breakdowns, mobile repair is the faster and cheaper option overall.
We'll tell you straight on the phone or when we arrive. If the job requires shop equipment, we'll help you arrange transport and get your truck to our shop at 3033 N Cherry Rd in Rock Hill.
