I have 2k miles, mainly garage kept, was just left outside a few times....i now have condensation and water marks on both headlight lenses. Thought was a fluke, but has done it repeatedly. I also have concern that my rear window now keeps filling with condensation and is now dripping on my back deck could only imagine what damage it will do in the long run. (Meaning damage to speakers, mold, etc) Shouldn't even be accumulating any moisture on the inside of the rear window?
There are know wet or moisture accumulating objects in the car, all windows have been quadruple checked to be sure they are up, but has happened more then once.
