Semi trucks are built to handle long distances and heavy loads, but even these workhorses can face mechanical issues on the road. With complex systems and constant wear, semi trucks are especially prone to certain types of breakdowns that can be inconvenient, costly, and even hazardous. At Billy Bob’s Repair & Tire, we provide 24/7 roadside semi truck repair in the greater San Antonio area. Here are five of the most common reasons that semi trucks break down.

Tire Problems

Tire issues are one of the most common causes of breakdowns for semi trucks. With the heavy loads they carry and the long distances they travel, tires are subjected to extensive wear and tear. Underinflated or overinflated tires, worn tread, and failure to regularly rotate tires can all lead to blowouts.

Brake System Failures

Brakes endure tremendous stress in semi trucks due to the vehicle’s size and frequent stops. Brake system components can wear down quickly if not maintained. Regular brake inspections and addressing any signs of wear—like squealing, grinding, or reduced responsiveness—can prevent more severe brake failures that could result in dangerous situations on the road.

Electrical System Malfunctions

The electrical system in a semi truck powers essential components like lights, batteries, and the alternator. Electrical problems—such as dead batteries or alternator issues—can lead to a truck that won’t fire up. Ensuring the battery is in good condition and inspecting wiring connections regularly can help avoid unexpected electrical issues that leave trucks stranded.

Engine Problems

Semi truck engines are built for durability, but that doesn’t mean they’re immune to issues. Cooling system problems, oil leaks, or issues with fuel injectors are all common causes of engine trouble. Regularly checking coolant levels, monitoring oil levels, and ensuring fuel injectors are clean are important practices to keep the engine running smoothly.

Transmission Failures

The transmission is responsible for shifting gears and handling the immense power output of the semi truck engine. Transmission issues—such as grinding gears, delayed shifting, or fluid leaks—can lead to costly repairs if not addressed early. Checking transmission fluid levels regularly and promptly addressing any shifting problems can go a long way in preventing transmission breakdowns.
