Two problems related to air bag have been reported for the 2012 BMW 135. The most recently reported issues are listed below.
Takata recall I received a letter from BMW USA dated September 2017 telling me that parts were available to satisfy this recall and to make an appointment right away to have the airbag replaced. I made an appointment and it was cancelled because the dealership "didn't have the parts and didn't know when they would get them". BMW cannot tell me when they will have the part, despite sending me a letter stating that they "have the necessary parts to complete this recall".
Takata recall - received a recall notice last year, but part remains unavailable, placing me at risk, particularly in hot south florida.
