Engine problems, transmission failures, and DOT issues can ground a truck for weeks. Get independent verification before you buy.
Semi trucks rack up hundreds of thousands of miles hauling heavy loads across the country. That mileage destroys engines, transmissions, and drivetrain components. A truck that looks road-ready might be hiding major repairs — or DOT violations that will keep it parked.
Worn injectors, turbo problems, EGR/DPF issues, and internal wear on high-mileage engines. Major repairs run $8,000–$30,000.
Worn clutches, damaged gears, and shifting issues in manual or automated transmissions. Rebuilds cost $5,000–$15,000.
DPF, DEF, and SCR system problems cause derates and downtime. Repairs range $3,000–$12,000.
Worn brakes, air leaks, and compressor failures. Repairs cost $1,500–$6,000 and can cause DOT violations.
Faulty sensors, wiring issues, and ECM problems cause no-starts and warning lights. Diagnostics and repairs run $500–$5,000.
Cracked frames, worn bushings, and damaged suspension components from overloading or accidents. Repairs cost $2,000–$15,000.
This is what repairs cost when issues go undetected. Our inspection is just $800.

Semi Truck Inspection FAQs
Most semi truck inspections take 2-3 hours. Trucks with sleepers or additional equipment may take longer to fully evaluate.
We inspect all major brands including Freightliner, Kenworth, Peterbilt, Volvo, International, Mack, and Western Star. Day cabs and sleeper cabs of all configurations.
Yes. We perform a diagnostic scan to pull active and stored fault codes from the engine, transmission, ABS, and aftertreatment systems. This reveals problems that may not be obvious during a visual inspection.
No. Our inspection covers many DOT compliance items, but we are not a certified DOT inspection station. However, we identify issues that would likely cause a truck to fail DOT inspection.
Yes. We evaluate the diesel particulate filter, DEF system, and SCR catalyst. These systems are expensive to repair and a major source of problems on newer trucks.
Yes. We road test the truck to evaluate acceleration, shifting, braking, and steering under real driving conditions. This reveals problems that won't show up sitting still.
If the truck has a sleeper, we inspect the interior condition, HVAC, electrical outlets, and any appliances. We document the overall condition with photos.
Yes. We inspect semi trucks at dealers, truck stops, terminals, and private locations across the country. We coordinate timing to minimize disruption.
The IronCheck Difference
We work for you, not the seller or dealer. Our only goal is giving you the truth about the truck's condition and DOT readiness.
Our inspectors understand Class 8 trucks — engines, transmissions, aftertreatment systems, and the problems that keep trucks off the road.
We inspect semi trucks across all 50 states. Dealers, truck stops, terminals — wherever the truck is, we can get there.
Most inspections scheduled within 24-48 hours. Report delivered same day or next business day.
A semi truck is a major investment. Don't let a bad engine, worn transmission, or DOT violations turn your purchase into a nightmare. Get the facts first.
