The tie rod is a part of your car's suspension system that connects the steering wheel to the wheels. When the tie rod breaks, it can cause the wheels to become misaligned, which can make it difficult or impossible to steer the car. In addition, a broken tie rod can cause premature wear and tear on your car's tires. If you suspect that your tie rod may be broken, it is important to have it inspected and repaired by a qualified mechanic as soon as possible.
