I HAVE A 2019 GMC TERRIAN WITH 2500 MILES. I WAS DRIVING IT AND THE CAR FLASHED LOW FUEL, CHECK TRANSMISSION AND CHECK ENGINE WARNING AND SHUT DOWN WHILE I WAS AS A HIGHWAY SPEED. I WAS FORTUNATELY OK, HOWEVER IT STRANDED ME AT A SPOT WITH MERGING TRAFFIC, NO SHOULDER AND NO POWER TO GET THE VEHICLE OUT OF THERE. THE VEHICLE WAS ABLE TO START UP SHORTLY, THEN I HAD TO DEAL WITH GETTING GOING AGAIN IN THIS PRECARIOUS SPOT.

NEED THE OPTION TO DISABLE THE AUTO START FEATURE.
