Tasked with the transportation of goods, semi-trucks help keep the economy running. That’s why it’s important to know what might cause them to break down and require towing. Since they’re heavier and built differently from other vehicles, semi-trucks usually have their own reasons for failing. To stay safe and keep interruptions to a minimum, it’s important to know the most frequent causes. 

5 Common Reasons Semi-Trucks Break Down 

1. Brake Failure 

Considering the heavyweight and frequent use of semi-trucks, the brakes are liable to overheat or corrode if a mechanic does not consistently maintain them. They can also leak brake fluid or even freeze in the winter. If you’re having trouble braking, stop driving and contact a towing service right away to have the problem fixed. 

2. Refrigeration Trouble 

Many semi-trucks carry goods that need to stay cool, so they pull refrigerated trailers. They can malfunction due to poor sensor calibration, faulty condensers, or fluid or air leaks. Have the trailer inspected by a mechanic before each haul and pull over as soon as possible if you receive an in-cab alert that the trailer’s temperature is off. Get a towing service and professional repairs immediately to prevent the goods from spoiling. 

3. Electrical Issue 

Like other vehicles, semi-trucks rely on a complex system consisting of an engine, battery, starter motor, and alternator to run. As long as you change the battery every three to five years and take your truck to a mechanic for regular maintenance on every other component of the system, you should avoid breaking down and needing heavy-duty towing. 

4. Low Fluid Levels 

The engine oil should be changed in a semi-truck every 25,000 miles if you want to avoid engine failure in the middle of the road. While checking the oil, review the coolant and brake fluid levels, too, so that you can prevent problems caused by overheating. Also, monitor the fuel tank level on your dash and stop to refill at a gas station when necessary. 

5. Bad Tires 

Before driving, examine the inflation and tread depth of your tires, and check that the axles haven’t moved out of position. As long as they’re in good condition, they should be fine while you drive, but a towing or roadside service can help if something happens to them anyway.
