Just received my copy of a safety recall for the Honda FiT.
For your information, the problem is described as follows:
"Splices in the floor wire harness may not be sufficiently sealed. In areas where road salt is used, the driver may get in the vehicle with a mixture of snow and salt on their feet. The water and salt that soaks through the carpet may enter these splices. Over an extended period of time, the wire splices may corrode, causing a faulty connection in the SRS occupant detection system (ODS). If this connection fails and the vehicle is in a collision, the ODS may not operate properly. As a result, the side airbag may deploy even if a person is leaning toward the outside of the front passenger seat, or the front passenger's airbag may deploy even if the front passenger weighs less than about 30 kilograms."
What should you do?
Contact your Honda dealer to schedule an appointment to have your vehicle's wire harness splices sealed at a convenient time for you. This will also allow your dealer to give you an ideas how long they will require your vehicle - usually less than a day - to perform the repair. the dealer will perform the necessary repairs on your vehicle, free of charge.
Hope this helps all you FiT owners out there.

Driver safely.
