Two problems related to seats have been reported for the 2012 BMW 535. The most recently reported issues are listed below.
Based on research it appears BMW has a long history of issues and even a recall on select years around the passenger seat sensor detector becoming faulty and impacting the ability of the air bags to deploy in a collision. This seems to a critical issue since it could result in serious injury to the passenger in the event of a collision.
The seat mat sensor (airbag) has failed on my vehicle. The item is a known problem and has been recalled on several other years, however it has not been recalled on the 2012 yet. I have contacted BMW and they refused to acknowledge the existing problem. They want me to pay $1200 to fix the item they know has failed on numerous years. This is a safety issue and they are not resolving it. They told me my case was closed and it would not be investigated any further then my phone call.
