What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2009 Audi A4 Cabriolet, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.
From owner reports, verbatim
TAKATA RECALL -- SINCE OCTOBER 2018, I HAVE BEEN RECEIVING MESSAGES FROM AUDI THAT THE REPAIR IS AVAILABLE AND THAT I SHOULD SCHEDULE AN APPOINTMENT IMMEDIATELY FOR MY SAFETY AND THE SAFETY OF MY FAMILY. SINCE THEN, I HAVE MADE SEVERAL APPOINTMENTS WITH MY LOCAL DEALER ONLY TO HAVE EACH OF THEM CANCELED DUE TO THE AIRBAG BEING ON BACKORDER OR OTHERWISE UNAVAILABLE. ON JANUARY 24, I CALLED BOTH MY LOCAL DEALER, AUDI EATONTOWN, AND AUDI CUSTOMER EXPERIENCE. THE FORMER TOLD ME THAT THERE ISN'T A SINGLE REPLACEMENT AIRBAG IN NJ WHILE THE LATTER THEN EXTENDED THE LACK OF AIRBAG REPLACEMENTS TO THE ENTIRE US.
TAKATA RECALL. I HAVE CONTACTED CLASSIC AUDI DEALER IN EASTCHESTER, NY SEVERAL TIMES BY PHONE, EMAIL, AND CHAT. THEY HAVE BEEN UNRESPONSIVE. TO DATE I HAVE NOT BEEN OFFERED AN APPOINTMENT TO REPLACE BOTH AIRBAGS. I CALLED THE AUDI ADVOCATE IN MICHIGAN, AND SHE PROMISED TO HELP BY CONTACTING CLASSIC AUDI AND PROVIDE ME WITH INFORMATION ABOUT WHEN CLASSIC AUDI WILL SCHEDULE AN APPOINTMENT. THIS IS TAKING TOO LONG.
Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
