I am with your dad on this. Heck, it makes me mad as he__ and I have never even met you. You brought it in for an airbag recall - they did something to it - it deployed while you were still at the dealership. They are lying to you big time. It is definitely their fault. How are you supposed to clean dust out from behind an air bag module? It’s a freakin’ Jeep!
I hope you are ok. I look at wrecked cars for a living for a major insurance company. Small folks, like yourself, who have to pull their seats up close to the wheel to reach the pedals are a lot closer to the bag when it deploys at about 200 mph. I hope you don’t end up with a black eye, or two. That is usually what I see when people catch an air bag directly to the face.
I am not one to suggest a lawyer, but this is one of those cases that the dealership needs to be held accountable. They are dead wrong and to make it worse, they are handing you this line of bull! I hate that you had this happen to you. Grrrrrrrrr.
