@Sibhusky, I am 100% positive that it's the minority. I have friends who own a total of NINE VW dealerships. Five different people. I asked all of hem if I could speak to the men {or in two cases ladies} who ran their service departments, as we did not to want this to be an issue. She parks outside. I also wanted to know as we're thinking about one, and we live right on the ocean in a wet environment. I clean the sun roof drains on our cars twice a year, for example.
One of these service folks was pretty non committal. As in we have very few that we have had to fix. The other four ranged from two who advised that they were still watching to see how it played out to two who said point blank that they would NOT recommend an SE or SEL. They knew that they were to be honest with me as a favor.
Like I said, my daughter would prefer to have an SEL, and a dry one. However, no way in hell could she deal with having a brand nw car out of service for there separate months in a year. What I learned was that most seem to require more than one fix. And there are many more repurchases underway than VW would like public.
In my opinion, by no means does it mean that a panoroof will leak, or that even a majority do. Maybe it's 10%? It's enough to be an issue. I have bought cars with the "sunroof deleted", to make them lighter, and stiffer. My brother drives an S4 Avant with it deleted. Have never bought one to avoid leaks.
It's a weird one. One way to absolutely avoid ANY potential, is to have no pano roof. So that was our daughter's choice. I had suggested that she might never have an issue. She didn't want to even think about it.
I'm pretty sure than every car we have had during her 29 year life has had a moon/sun/pano roof }or was a convertible. She's doing fine without one!
I don't believe that any of the Tiguan roofs have been leaking, and they are huge. Odd stuff.
Fingers crossed that more remain dry!
