Example complaints
Air bags: “Porsche has a fault with their 911 and boxster automobiles that causes an airbag fault light to illuminate on the instrument cluster. The cause of this is well known by Porsche and has been addressed with a Porsche TSB 911 (996) 1/04 6924 airbag warning light comes on: fault codes 45, 46, 48 and 49. This TSB outlines the problem and gives the procedure for correcting it. I believe this to be a safety issue that relates to the seat belt system and therefore should be covered by an extended warranty. The details of my situation are below. …”

Has there been a recall issued for this problem?”
