I bought my '09 135i a week ago. Yesterday was the first truely sunny, warm day. When went out to the car at lunch, there were several bubbles on the dashboard, just behind the windshield.
One was 2" by 1" and maybe 1/2" high. Clearly something in the foam underneath had outgassed and pushed up the covering.
Is this a known defect?
The only upside is it is warranty work. I bought the car from CarMax and the service guy I worked with said there is both their 30 day warranty (which covers everything) and still two months of BMW warranty on the car. So, one way or another, it will be covered by warranty.
