Side/window Air Bag problems of the 2015 Chevrolet Tahoe

I live in a fairly arid climate, where rain doesn't occur frequently. A couple of months ago, after my Tahoe had been sitting in the rain, I noticed water dripping from the inside door pillar when I opened the door. I just assumed it was water than came in from the outside when I opened the door. Then about nine days ago, while driving in the rain, water began dripping from the top center console area, in a steady stream. When I took it into the Chevrolet dealer they said that the seal on the hi-frequency antennae (shark fin antennae), over the driver's side was faulty, and that water was leaking in through it. Since there was not a recall for my VIN, and since rain was predicted to continue for several days, I had no choice but to pay $452. 32 to have a new antennae installed. The service department did what they could to dry the area out in between the roof and the ceiling and left the cover off the side driver's airbag so it would dry, telling me to return in a week so they could replace the cover on the airbag. In addition to being out a lot of money, I am concerned about the side airbag possibly malfunctioning after being wet over a period of time.

A-pillar water leak - vehicle is not designed to have water in the a-pillar. Water may have damaged side air curtain.
