Sometimes if I put my purse in the passenger seat, it triggers the seat belt alarm. Weight is about 2-3 lbs. The alarm will not turn off even if I move my purse to the floor. Must turn off the car, put purse in floor and then turn it back on. Dealer says that it is caused by my cell phone in my purse and that there is a bulletin out about this problem. The fix is to never put my purse in the passenger seat.
