So i've noticed that probably 1 in 3 times my passenger seatbelt warning sound will start going off when i'm driving with no one sitting in the seat, sometimes I have my phone and a small bag on the seat but that shouldn't be enough to turn the air bag on and start giving the seatbelt warning alarm to go off. I know with my luck ill tell the dealer about it and they wont be able to replicate the problem, just wondering if anyone else has experienced this?
