I have heard that sometimes you can tell the dealer that you heard there is a silent recall on the issue that you are having. Alot of them are not up to speed on these recalls. What happens is that they are to try all other remedies before considering the silent recall. If you do a search on the internet you can find some information on silent recalls. there might actually be one for these issues. I'll look myself too and see if I can't find something.
I recently had one dtrl out but it was just the bulb.
