I was wondering if anyone had their rear defogger repaired under warranty. I recently noticed that one of my defogger grids stopped working. I must have cleaned the back window a couple of weeks ago, but I was always careful when doing that. I would always clean and wipe the glass horizontally to avoid breaking the grids. I don't know if the dealer would say it would not be covered because they assumed people damaged the grids while cleaning them. Has anyone had that problem when getting it repaired? If they would not cover it, I would just repair it myself with one of those kits. I have repaired them in the past but if I could get them to do it I would since i got the extended warranty on the car.
