What problem can cause tracking issues while driving?

Incorrect alignment angles can significantly affect a vehicle's tracking, which is the ability of a vehicle to travel straight without requiring constant steering corrections. When alignment angles are off, it can lead to uneven tire wear, pulling to one side, and difficulties maintaining a straight path on the road. Misalignment causes the wheels to point in different directions relative to each other and the vehicle's body, which directly disrupts smooth tracking.

The other options, while they can contribute to vehicle handling and comfort, do not specifically address the directional aspect of tracking in the same way that alignment does. Unbalanced tires can cause vibrations but may not directly influence how straight the car travels. Worn suspension components can impact ride quality and handling but do not solely affect tracking unless they severely affect alignment. Under-inflated tires can lead to excessive tire wear and could affect stability, but alignment issues more directly disrupt how the vehicle tracks down the road. Therefore, incorrect alignment angles are the primary cause of tracking problems while driving.
