Takata recall. My car is experiencing the passenger occupancy sensor mat failure. BMW is not honoring extended warranties and denied my claim because my car is a 2007. It was built in december of 2006. Both the airbag warning light and the passenger airbag not working light are illuminated.
On 8/19/2015 while leaving my neighbor hood going around 25 MPH my passenger side air bag randomly deployed. The car is a 2007 BMW z4 with only 32000 miles. I didn't hit a pot hole or anything that might have set it off.
