2008 BMW X5 Seats Problems

I HAVE BEEN EXPERIENCING SEAT BELT PROBLEMS FOR YEARS. THERE'S A RECALL ON THE BMW X5 BUT I'M NOT SURE WHY MY VEHICLE IS NOT ON THE RECALL LIST. THERE ARE 3 OTHERS THAT HAVE THE SAME SEAT BELT ISSUES. *TR

WATER LEAKAGE ON DRIVER SIDE REAR- AS WELL AS ACCUMULATING IN SPARE TIRE WELL SUBMERGING BATTERY IN 3 INCHES OF WATER. HI-FI AMPLIFIER - BLUETOOTH- NAVIGATION- RADIO- SOS DAMAGED FROM THIS. ALL WINDOWS SHUT AND VEHICLE FILLED WITH WATER.

WHEN A PEOPLE SEAT ON THE PASSENGER SEAT, THE LIGHT "AIRBAG OF THE PASSENGER SEAT IS OFF" IS ON. AND THE LED PANEL SHOWS "RESTRAIN SYSTEM MALFUNCTION". I GET MY CAR CHECKED AT THE DEALERSHIP, THEY SAID THIS IS DUE TO THE FAULT OF THE SENSOR IN THE SEAT AND WILL MAKE THE AIRBAG NOT DEPLOY IN AN ACCIDENT. ACTUALLY, THIS PROBLEM HAS BEEN THERE FOR A WHILE BUT ONLY HAPPEN OCCASIONALLY (ONE TIME A MONTH), AND CAN BE SOLVED BY CHANGE SITTING POSITION A LITTLE BIT. WHEN I CHECKED IN THE SERVICE, NOTHING WRONG WAS FOUND. HE SAID THE SAME PROBLEM EXISTS IN OLDER MODELS (E.G. 2005, 2006), WHICH ARE IN THE RECALL LIST OF BMW. BUT MINE IS NOT IN AND I NEED TO PAY $1400 TO GET IT REPAIRED. I THINK THIS IS A REALLY IMPORTANT ISSUE SINCE IT DISABLES THE AIRBAG, WHICH IS THE MOST IMPORTANT...
