I called my dealer when that happened to me and they said that it is covered. I think it wasn't technically a recall... but I think they had quite a few others with similar problems so they just took care of it. So you may just want to call your dealership and explain it and ask if there would be any cost to you. (I pretty sure someone on mamasource told me to do that about a year ago and at that time my minivan was about 4 yrs. old.)
Just a thought... it can't hurt to ask.
