Know the Warning Signs

Top 5 Reasons Trucks Break Down on the Road

Know the warning signs — and call us before a small issue becomes a big one.

1

Dead Battery

The most common reason for a no-start situation. Check the charge and condition of the battery.

2

Alternator Problems

The alternator may not be charging the battery — the electronics and systems may shut down.

3

Brake System Failure

Worn pads, leaks or low air pressure can lead to brake failure — a serious safety risk.

4

Engine Overheating

Low coolant level, faulty thermostat or radiator can cause the engine to overheat.

5

Worn Hoses & Belts

Cracks, wear and tear can cause hoses or belts to break, leading to serious damage.
