I did not read through the thread to see if this had been mentioned but knew I had come across it recently.
but there you have it, even Subaru acknowledges this issue AND blames it on high heat and humidity.
ALSO, when I bought my car and called Subaru they confirmed that this warranty had already been done on my car. I live in a high head area (for part of the year) and it is not too sticky. however, my door panels are on the top.
