Front Air Bag Sensor Control problems of the 1999 Buick Lesabre

I was sitting at a red light when my air bag from the steering column deployed in my face. I did not hit anything. It was on or about 1/25/18. About a week prior to this event my horn began to steadily blow inexplicably. I did not have any reason to suspect anything other than a malfunctioning horn so I disconnected the wires to the horn. When the air bag deployed about a week later I concluded the air bag was inflating inside the steering wheel applying pressure to the horn sensor. I took it to the dealer who, after weeks of investigation, concluded they could not do anything to repair it and suggested I call general motors customer assist center. After reviewing pictures, (no one actually physically looked at it) gm decided corrosion to the sensing module caused the problem. I contend they have a defective valve which overtime began leaking gas into the air bag, hence the issue with the blowing horn.

The contact owns a 1999 Buick Lesabre. The contact stated that the air bag deployed independently while the vehicle was parked. The contact took the vehicle to a certified mechanic who diagnosed that the air bag and air bag sensor needed to be replaced. The manufacturer was made aware of the failure and opened a case on the contact's behalf. The approximate failure mileage was 58,000.
