Well, my Mazda 6 just had it's first problem tonight.
This same thing happened with the 626, and it's obnoxious.
The seatbelt light came on, even while I was wearing the seatbelt, and stayed on while I was driving.
It also let off this equally obnoxious warning beep telling me I needed to put my seatbelt on.
Any ideas on how to resolve it, without taking it to the dealership (like I did with the 626)?
