2018 BMW 540I Air Bagssensoroccupant Classification Problems

The vehicle throws a “passenger restraint system malfunction” every 5 minutes while driving. Based on discussions on bmw forums, this is a common issue among several models of BMW. The issue seems to be caused by loose wires/sensors beneath a he passenger seat.

- Passenger Airbag and passenger restrain system malfunction. - Malfunction of passenger airbag not deploying during accident even passenger seat is occupied with recommend weight. - Issues has been reported to Dealer. In turn dealer responds to as "External Factors" with issue could be presence of moisture in the seat. - Passenger Airbag light illuminates - Warning was never consistent. After reporting to dealership warning stays permanent and advised to replace seat mat sensor. - This has been a know issue over a decade and 2017-2018 manufactured BMW 5 series (G30). - This is clearly a poor material and workmanship costing people life's.

Vehicle reports "Passenger restraint system malfunction" upon startup, even when passenger is not in seat. Passenger airbag light turns on. In this state the vehicle defaults to deploying the passenger airbag no matter what, even if passenger weighs less than 45 lbs. BMW of North Scottsdale inspected and recommends replacing the passenger seat sensor mat for $3600, not covered outside of factory warranty.

Passenger seat indicator light keeps going off intermittently. Dealer says its a seat pad issue. We identified it in 2018 but dealer was not able to fix it and it continually keeps happening and didn't do anything because dealer did not fix it at that time. Now dealer is re-diagonising it saying it is a different diagnostic code but we have seen the same issue since we got the car. After reasearching this, there was a recall in 2017 with similar issues. It is related to the sensor and if not properly working, the airbags may not deploy when needed. This appears to be a safety feature of the car so should be recalled like previous. Please investigate.
