I HAVE A 2009 GMC SEIRRA AND IT SHUTS OFF FOR NO REASON AT ALL WHILE YOU ARE DRIVING.AND I FEEL THIS IS VERY DANGEROUS.THERE ARE SEVERAL COMPLAINTS ABOUT THIS AND THERE SHOULD BE A RECALL ON THIS.MY VEHICLE HAS LESS THAN 50,000 THOUSAND MILES ON IT.AND OF COURSE IT STARTED HAPPENING 2-MONTHS AFTER THE WARRANTY WAS UP. *TR
