Any opinions / info on the Platinum Shield Protection corrosion control module for my new Terrain? Any information on this would be appreciated.

Thanks!

Groups like consumer reports say that these are not necessary any more, mostly because factory paint and rust protection is so good now. These are just a big profit center for dealerships.

The basic modules are just little batteries that get attached to the frame of the vehicle; the current prevent the cathodic reaction that causes rust -- it's chemistry 101. If you're really hot for it, 90% of the time you can get it much cheaper after-market.
