Have you had problems with these bulbs burning out? This may only apply to the quadcoupe but I don't know if the sedan uses the same bulb. My new quadcoupe.......week and a half old with 800 miles on it........had the front right dtr/turn signal/running light bulb go out this weekend. I took it over to the dealer today where they replaced it under warranty no problem then the service guy mentions they've replaced quite a few and don't know why they're going. My guess is hopefully the factory just got a bad batch of bulbs and it's not something like an engineering flaw where they used an inferior bulb design. So I'm wondering how many others may have had this happen and what kind of mileage? Charles
