Side/window Air Bag problems of the 2008 Kia Motor RIO

(2008 kia Rio) - passenger side air bag fails to stay on. . . . It comes on maybe every 1 of 5 times. . . . I have tried every thing to get it to work. . . . When stopped a stop sign I turn the car of and back on (nothing). . . It needs a key to turn it on and off . I have even put weights on the seat but nothing . . . . . Will not turn on . . . . . . Then some days it turns on just fine . . . . . But!!!!!. . . . It also turns off while driving ( after a lot of research I found multi able complaints on the passenger side air bag this needs a recall (a on of key) and to be looked at on all cars like this . . . . . . The kia lot will look at it soon hope its not on one of its I want to work days so I can show them what I mean. . . . . . Also . . . The sensor part cost around $400 and several people said they had to replace them 2 or more times . . . .

The passenger side air bag does not come on with my wife setting in the front seat. She weights 110# and the dealership stated that she was to light to turn the airbag on. It seems to me that a person 110# should turn the airbag system on. We feel that there is a problem with the design of the system. There was no accident yet but if it did occur there would be no airbag protection for the passenger. Please take action as this is a real safety issue.
