Open the full vehicle complaint log (all categories)It was noted there is fogging, spiderweb type cracks, and discoloration on the inside of each headlight lens. It was discovered through conversations at the dealership and online research that a chemical reaction between the factory lens coating and the gas emitted by the headlight bulbs was the likely cause. Lumen output has gradually decreased as the issue grows worse and both lenses become more opaque in appearance. The car is available for inspection. We are asking NHTSA to investigate this issue for the following reasons: 1) This is a growing safety issue as lumen output is steadily decreasing 2) This is unrelated to regular service/maintenance or any culpability on behalf of the owners 3) Absent replacement, this issue cannot be corrected by the owners 4) It has been reported to be a growing issue among numerous Porsche Macan owners. I asked Porsche if it was covered under the warranty, they stated it was not. They did examine the car. No warning messages.
THE CAR WAS PARKED IN THE GARAGE AND THE PANORAMIC ROOF WAS SUDDENLY SHATTERED WHILE I START TO DRIVE THE CAR ABOUT HALF MILE. AT FIRST, I THOUGH IT LOOKS LIKE IT WAS FROZE BUT THE GLASSES START TO FALL APART. THE CAR IS NEW, I JUST BOUGHT IT FOR 3 WEEKS WITH 700 MILES ON IT. NO STONES OR ROCKS EVER HIT THE SUNROOF.
