I've only owned my GT for a few months and know the detailer at the dealership where I bought my Pontiac. He swears he didn't use any type of cleaner that would cause this problem, however the surface on the top of the steering column is sticky as if caused by a chemical reaction. Nothing will clean it, so I was thinking of maybe sealing the surface? I seen this happen on mid to late 2000's Lexus sedan dashboards. No repairing this, the entire dashboard has to be replaced. This isn't so much a function problem but it looks bad with cloth threads and shop towel pieces stuck to it. Anyone else notice this or maybe it was the detailer's fault after all. Thanks for sharing
