Flooding - sunroof drain problems
My '06 BMW 530xi experienced electronic failure twice ('08 & '09) while my wife was driving to work at night while it was raining. The lights went out and the windshield wipers stopped working. The dealer did not inform us that there was a TSB related to this problem and labeled it a failure due to environmental influences. The total cost for repairs were approximately $7000( none of which was covered by our extended warranty). The panoramic sunroof drain was the problem each time and no maintenance was ever performed to prevent recurrence. No solution is forthcoming from BMW North America. Clearly this is a safety issue that is not being advertised or solved. Any interest in a class action suit about this recurring problem?
