How hard is it to get VW tu honor there 12 years rust warranty ?
I guess it depends on where the rust is and how it started. I just went through this with a recently purchased '06 Jetta. The seller had already submitted a corrosion warranty claim on the car prior to me buying it. It was just approved a week ago and they tell me they're replacing both front fenders, both left and right rocker panels, repairing both quarter panels, and replacing the trunk lid. It looks like I'll have to pay for the two door panels that need to be replaced.
What I find odd is that the doors were rejected for warranty by the VW dealer as the rust was determined to be from regular "wear and tear". If I understand it correctly, when the dealer inspects the car there are certain items they can reject on the spot and not even submit to VW Corporate for warranty. Had I been there and owned the car at the time, I would have argued that part of the claim, at least a little bit.
It's not a big deal to me, and I'm not complaining as they are replacing much of the original steel anyway. I just have to wonder if the door replacements might have been covered under warranty had they been submitted in the first place.
It seems to me, in my limited experience, that VW is pretty good about it.
A good friend of mine just had something like $4800 worth of bodywork done on his '05 Jetta wagon, all under the corrosion warranty. I think they replaced all four doors and the hatch, but rejected the rust on the quarter panels.
