I have seen a couple posts on this subject but since we are now 25 days straight with rain in Seattle I know it is true.

The problem is that the OnStar antenna can cause problems when water slowly sneaks in there via the antenna. This happened to someone at a car wash and now again is happening to me.

So if your onStar starts to flake out and it has been wet out go to the dealership and tell them to reseal the antenna.

Better yet tell them to do it if you don't have a problem yet.

Reseal where the black wart (engineering term for antenna base) where it mounts to the roof, or the little thingy (engineering term for comm part of antenna), that screws into the base?

I'll second that. I had that problem and they had to re-seal the antenna housing.
