NHTSA Complaint #11395505 — 2015 GMC SIERRA 2500

2015 GMC SIERRA 2500 DURAMAX DRIVING EAST WITH THE FLOW OF TRAFFIC ON 80 REACHING THE SUMMIT TOWARDS TAHOE. WE SUDDENLY EXPERIENCE AT "CHANGE FUEL FILTER" WARNING WHICH ONLY LASTED APPROXIMATELY 20 SECONDS BEFORE THE MESSAGE THEN READ "DERATING". UPON THIS SECOND NOTIFICATION WE IMMEDIATELY LOST POWER TO THE ENGINE WHICH RESULTED IN REDUCED BRAKING CAPABILITY AND STEERING AT LITERALLY THE TOP OF THE MOUNTAIN. WE WERE TRAVELING IN SNOWY CONDITIONS WITH MANY SEMI TRUCKS AROUND US. WE TRIED TO SAFELY DRIFT TO THE SHOULDER TO THE SAFEST POSSIBLE PLACE. THE SUDDEN LACK OF POWER LEFT MY FAMILY, INCLUDING 3 CHILDREN, IN A VERY DANGEROUS POSITION. WE ENDED UP BEING STRANDED WITH TOW TRUCKS BEING VERY SCARCE AND CHALLENGING TO FIND. THE NEAREST RENTAL CAR TOOK 2 HOURS TO GET TO, AND WE HAD TO SHUFFLE KIDS ALL OVER. ONE CHILD WAS CRYING AND SCARED TO DEATH AT ALL THE CARS ZOOMING BY AND OUR INABILITY TO MOVE. IT APPEARS THAT THE CP4 FUEL PUMP MAY HAVE FAILED LEAVING US ALMOST INSTANTANEOUSLY IN AN UNSAFE SITUATION.
