Front Seat Head Restraint problems of the 2011 BMW 328

I am receiving a 'passenger restraint malfunction' message on my dash and the seatbelt and airbag light are stuck on. Online BMW states "the oc3 mat needs to be replaced. Check with your dealer, we extended the warranty on some models. " I checked with my dealer and this does not qualify. They will not cover this safety repair. I cannot safely have anyone ride in the passenger seat, and the seat ceases to move as well. My dealer states it costs $1350 to fix and they would need to order in the part and have my vehicle for 2 days. This is a safety issue. Safety issues should not have an 'expiration date' as to when the dealer will or will not cover it. The care is 7 years old and has 63,000 miles. This defect was covered for the 2006 and 2007 models and became a recall. I see online in forums others are experiencing this in the 2011 model. I am forced to pay a mechanic to fix this now.

Stopped after exciting freeway with traffic flow. SUV came up behind me and didn't stop and hit me from behind going 40-60 mph. Impact threw me back then headrest deployed and punched me in the back of head which I then hit searing wheel. Instantly felt pain in neck and head. Taken by ambulance to hospital. 2 c. T. Scans done,chest xrays, and 2 mris of neck and brain showing spinal stenosis of cervical region, bulge of cervical disc without myelopathy. I also sustained a concussion and whiplash which is still present as of today. Car totalled. One of doctors stated impact from headrest deploying was same as being punched in back of head from a 200 lb. Man.

Getting "passenger restraint system" error for no apparent reason at all. I'm afraid the airbags won't deploy in case of accident.
