The air bag on the 2008 Ford Mustang is to close to the front of the seat,I purchased one for my wife, she sits up right in the passenger seat with her back against the back of the seat ,the air bag was turn off when she was a passenger in the car,Ford is aware that this happened and said that they could not do anything about it,we had the car less than one month and it was in the shop 3 times during this time,we had it returned under the lemon law,but this is a safety problem if you have to sit so close to the front of the seat in order for the air bag to be turned on. We have a 04 f-150,a 04 gran marquis and drove an explorer,and a taurus while her car was in the shop and never had the air bag light to come on. Ford said that they could not find fault with the light, just the placement of the sensor being to far to the front of the seat. A simple move closer to the rear of the seat would solve this problem.
