My crossfire has an intermediate seatbelt alarm that goes on when everyone has a seat belt on. It's just happens we I can drive off and in 5 minutes it starts on then off then on .....
Anyone else experience this issue?

 

How long has it been going on? I would say that the passenger seat belt sensor switch or wiring has a problem. You can fix it or disable it.

 

How do you disable? Driving me nuts!

 

Here’s a nice list of things to do to go with the seat belt chime disable.
