Interesting that I stumbled upon this thread today. Mine did this yesterday. Nothing out-of-the ordinary during my commute home, other than passing a couple of slow-asses in the left lane, but that's normal. STRONG smell of burning clutch as I put it in the garage. Lord I hope mine's not developing problems after 1700 miles of nearly perfect operation.
I'm not going to bother taking it in unless it persists. If I take it in smelling normally, they're not going to do anything anyway....and I don't want to go through a flash and re-learn if it's not necessary.
