Did you just buy it recently? That's what happened to me. I purchased it used from a BMW dealer and only had a 30 day warranty on it. Took it back in 45 days or so and just demanded they do it as it is a fire hazard. Made up some BS story about it burning my wife, yada yada yada. And they replaced it.
