I have a 2006 ford Explorer 4.0L. That the airbag light came on for about 2 minutes.Then the light went off . This occured while sitting in a drive thru. Is this normal or am I about to have issues with the air bag. The car has 45,000 miles on it and i have already had to replace radiator and then a bypass hose ruptured above the water pump. I am starting to think this model is junk!
