Quick Answer

The most common complaints about International Trucks include a host of electrical and wiring failures, high-pressure oil lines and pumps leaking and failing, transmission issues, camshaft failure and poor service records.

International Trucks produces trucks as small as a 4500 series chassis truck up to a full-sized tractor for pulling a 53-foot trailer. Most of the common repair complaints are prevalent in trucks of all sizes from International, which includes commercial vehicles, such as tow trucks, delivery trucks, roll trucks and refrigerated trucks. After 2004 these vehicles typically had the 6.0 liter diesel engine as the factory engine as well as the MaxxPro Star engine in larger trucks.

Electrical and wiring failures typically occur in the emissions, fuel and cab control systems, at times rendering the trucks completely inoperable until repaired. High-pressure oil systems in International Trucks commonly spring leaks or have injector failures, leading to other engine related problems. The routinely poor service records of International dealers compound all of these issues, leading to prolonged vehicle downtime and complicated repair processes.
