What experiences are you basing this on?
Anyways, I have dealt with Fender a few times on repair issues and they were great to deal with. Not Sadowsky or Roscoe great, but great for such a large company.
The issue IMO is that the retailers you are dealing with are morons. Get Fender to recommend a reliable retailer (even a GC would likely be better) and take/ship it to them.
Fender IME always stands behind their products while under warranty but remember than they don't generally do warranty work direct. They can only do so much to ensure their network of mom and pop music stores have a clue about their products.
