I started my car in the morning, per my usual routine. After a few seconds, I heard a very loud bang and the car stalled. A few seconds later, there was a large amount of smoke coming from under the hood. I opened the hood to see a large fire had started. My son, who heard the loud bang, came outside and saw the flames from under the hood. He ran into the house, grabbed a fire extinguisher, and attempted to put out the fire. He got the fire out but it was difficult. I had the car looked at by a mechanic and told me that the intake manifold had literally exploded. He has stated that he has never seen anything like this. It appears that the exploding manifold ruptured a fuel line. He told me there was a recall on this vehicle relating to a rupturing manifold and leaking fuel but that my vehicle had already had the recall performed. He thought that the new parts may be defective which is why I am reporting this incident.

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.
