What are the disadvantages of a car sunroof?

Disadvantages of car sunroof: expensive, reduced body rigidity safety coefficient, sunroof prone to dust accumulation. Here is relevant information: Expensive: Whether choosing a car with a sunroof or installing one separately, it requires additional expenditure. Reduced body rigidity safety coefficient: In the event of an accident, when the vehicle side is impacted or the vehicle rolls over, the B-pillar is the part that most tests the body's rigidity. The B-pillar runs circularly through the central area of the body, where the sunroof is located. Some sunroofs, in pursuit of larger area and aesthetics, minimize the roof longitudinal beams of the B-pillar. When a side impact occurs or the vehicle rolls over, the body is more likely to be compressed and deformed.
I've always thought that while car sunroofs may look premium, they actually come with quite a few hassles in practical use. Safety is a major concern—in rollover accidents, the roof's structural integrity is compromised, making it more prone to collapse and endangering passengers. Maintenance is even more of a headache: the sealing rubber deteriorates quickly, often leading to leaks within about five years, and during heavy rainstorms, water damage to the interior is common. The added weight increases fuel consumption; I've noticeably spent more on gas driving in the city. Noise is another issue—at highway speeds, wind noise drowns out music or navigation. I hardly use it—my sunroof gets opened fewer than a handful of times a year—and it eats into headroom, making tall drivers like me feel cramped. Repair costs are steep, with seal replacements or motor repairs running hundreds, making sunroof-free models a smarter choice.
