Hello, I have had a problem with my front passenger seat sensor buzzing when I am driviving without a passenger in the seat. The first time I mentioned this to the dealer they found a defect in the sensor. It has since happened again-one time when I had 1/2 gallon of milk on the seat. The dealership is telling me that I cannot place anything on the front seat or else I will activate the sensor. Has anyone had this problem or has anyone seen what the weight restriction is for placing items on the seats and activating the device. Thank You. undefined
