I just had this happen but had some others things happen at the same time. I heard a static sound coming form the car while driving. When I came to a stop the car turned off. I was able to start again and the sound come back a little then went away. I noticed the econ button was on even with heat and it wouldn't turn off. I saw a little coming from the front and a smell I have never smelled before. THink it is the same thing?
