What common issue can occur with improper panel alignment?

Improper panel alignment can lead to increased wear on suspension and steering components because misaligned panels can contribute to irregular stress distribution across the vehicle's structure. When panels do not fit together as designed, it can result in components that are subject to uneven forces during driving, especially when navigating turns or irregular road surfaces. This misalignment may ultimately affect how the vehicle's weight is distributed and how road shocks are absorbed, thereby leading to accelerated degradation of suspension and steering components over time.

In contrast, the other choices do not directly relate to the mechanical implications of panel alignment. Reduced fuel efficiency is typically associated with aerodynamic issues or mechanical problems rather than panel alignment alone. Changes in vehicle color typically pertain to surface treatment or paint issues, which are not influenced by the structural alignment of panels. Easier cleaning of surfaces would not be a general consequence of alignment issues, making it an irrelevant consideration in this context.
