    Transmission switched to low gear and stayed there - so you can only travel at about 15-20 mph. Mercedes dealership says that the electronics force it into a "safe mode" when this happens so one can not damage the transmission. Despite it being covered fully by warranty, it makes me uneasy in a car with 11k miles!!!
