Air Bag Light On problems of the 2007 Ford Expedition

I was taking my daughter to a dr appointment and the airbag light came on. It has gone off and on since not at a specific time but it always occurs when the vehicle heats up.

Air bag light keeps coming on and off while driving. Dealer can only check if it is on at time brought in no luck yet but why is it faulty. Ford will not cover to look at so frustrated laws need to change on airbags and warranties. Im told it is only covered in the first 36000 miles anyway.

The first occurrence was the transmission slipping on acceleration and stopping or going up hill. Its been to our Ford dealer where we purchased it and at first they felt it and said they fixed it but now everytime I take it in for that or the ac blower going off and on they say they don't feel or see anything it gotten ridiculous. In the freeway I-10 me and my son were trying to accelerate on and almost got hit by a semi truck the vehicle would not go fast enough. I wont bother with the dealership here in town they don't care. It has happened many times and now the air bag light goes off and on in temperature change it seems like. Our dealer fixed the door handle but now any rain the inside of our door fills with water and they say its not there fault and wont fix that either. Very disappointed with Ford. Spoke to them about the air bag and they also say they wont fix. We have had nothing but problems with this 40000 SUV very dangerous to drive and its suppose to be a family vehicle. . . . Right we get no update or recalls info and our dealership is the worst I've ever dealt with.
