Rear Tailight internal stress cracks causing condensation moisture and dust buildup. Dealer says this is normal, vehicle is only 2 years old, 20k miles and under warranty. Seems like there is a seal issue with the moisture and dust due to the internal cracks of the taillights. I've read on Rennlist and seen on YouTube that this is occurring for others as well that own 992 911's. The taillights were inspected by two dealers, one said it was normal but did not mention cracks, another dealer confirmed it was due to "stress cracks" inside the taillights but that this is normal. The manufacturer (Porsche North America) was contacted and responded that since 2 dealers could not find an issue a replacement was not warranted. I've had numerous other faults with the vehicle in 2 years of ownership, also having to replace the front windshield due to delamination of the windshield seals but I was not included in the recall that affected other owners with the same issue.
