4 Common Problems that Lead to Semi Truck Breakdowns

Semi trucks are the backbone of the transportation industry, but they endure significant wear and tear due to long hours on the road. Even with regular maintenance, breakdowns can still occur, causing delays and costly repairs. At Bob’s Road Service, we provide expert semi truck towing and repair in the greater Cayuga, IN area. Here are four common causes of semi truck breakdowns.
Tire Problems
Tires are among the most frequent causes of semi truck breakdowns. The immense weight and mileage that trucks handle make their tires vulnerable to blowouts. Potholes, debris, and extreme temperatures can further accelerate tire deterioration. Regularly checking tire pressure, alignment, and tread depth is crucial to prevent unexpected failures on the road.
Electrical System Malfunctions
A semi truck’s electrical system powers everything from the starter motor to the lights. Issues such as dead batteries, faulty alternators, or damaged wiring can cause the truck to stall or fail to start altogether. Corrosion and loose connections are common culprits behind electrical failures. Keeping battery terminals clean and checking for frayed wires can help avoid unexpected electrical breakdowns.
Cooling System Problems
Overheating is a major concern for semi trucks, particularly during long hauls or hot weather conditions. A malfunctioning cooling system—which includes the radiator, coolant hoses, and water pump—can lead to engine failure if not properly maintained. Leaks and low coolant levels can cause excessive heat buildup. Regularly inspecting and flushing the cooling system helps ensure that the engine remains at a safe operating temperature.
Fuel System Issues
Fuel system problems can bring a truck to a halt without warning. Clogged fuel filters and failing fuel pumps can disrupt the flow of fuel to the engine, leading to performance issues or complete shutdowns. Using high-quality fuel and replacing filters on schedule can help prevent fuel system failures.
