International Common Problems

Common International Truck Breakdowns 

Braking issues on a commercial truck

Brake-related problems can lead to costly repairs at best or more importantly cause safety concerns and vehicular accidents. A truck’s disc and drum brakes are exposed to consistent heat, pressure and friction, which means they wear down without the right maintenance. Brake issues are usually related to things like external corrosion and wear, minor leaks and internal water contamination that causes airline freezing during the colder months.

Tire repairs and challenges on a heavy duty truck or trailer

When it comes to physical issues with your truck, tires are typically considered to be the most important components of any vehicle. A simple flat really isn’t that simple and can sideline a truck for hours. Tires are the leading cause of truck problems for drivers, making up around 1/2 of all roadside failures. These failures are related to under inflation, low tread depth or misaligned axles. Always make sure to have each of your tires inspected thoroughly before you hit the road and look for those issues.

Electrical problems in a commercial truck

Electrical systems in a heavy Duty Truck are made up primarily of the starter motor, alternator and battery. If one or more of these mechanical parts fails to function properly, your truck can’t continue on. Signs that your problems relate to your electrical are things like flickering lifts or lowering or dimming lights, dead batteries, unusual burning or weird plastic smells and clicking sounds when the engine starts up.

*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. These issues are especially pronounced on trucks with International's 6.0 liter diesel engine, introduced in 2004. This engine was the subject of several class-action lawsuits for the chronic failure and poor service record of trucks produced with the 6.0 liter diesel engine.

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.
