The rear bumper of my recently purchased vehicle is physically misaligned and structurally deformed. Dealership service personnel initially acknowledged the defect and ordered repair parts, but later refused to fix it, claiming it is 'within factory specification.' This structural misalignment directly impacts the orientation of the vehicle's rear safety sensors, blind-spot monitors, and cross-traffic radar systems. A misaligned bumper housing can cause these driver-assistance systems to miscalculate distances, fail to detect hazards, or trigger false emergency braking, creating an immediate collision and safety hazard.
