Power Steering Pump Problems of GMC Sierra 3500

I was traveling on a busy roadway at 40 mph when fuel filter warning light came on suddenly and vehicle lost all power - including the loss of power steering and power braking. Thankfully I had not yet entered the highway and was able to slow vehicle down but with great difficulty and not injure anyone around and that day was not towing a load. Vehicle would not restart. I had it towed to nearest dealership who then informed me that the "bosch cp4 fuel pump" had exploded sending metal shrapnel throughout the entire engines fuel system. The only fix was the entire replacement of the fuel system at a cost of over $11k. I had just purchased the truck 3 months prior. Upon hearing this, I see this has been a frequent safety problem affecting a whole line of 2011 - current gm, Ford, Dodge, and Jeep diesel vehicles equipped with the cp4 pumps. There are numerous lawsuits underway for this failure including one of a major accident while towing (what these trucks are made for) because of loss of power steering and braking upon engine stall after fuel pump explosion. The gm technical service bulletin for reference is #16-na-102. In addition, the NHTSA has received two manufacturer technical service bulletins on this very safety issue. This is very much a recall worthy safety issue. Losing engine power and loss to all power steering and power braking in these vehicles is beyond dangerous. In addition, when it is happening to vehicles designed to tow weights in excess of 30k pounds trailer load behind the affected vehicle the danger is amplified that much greater. Please issue a recall immediately. People's lives are very much at stake for gm's failure to remedy a known safety issue. Gm lists it as only a "hard start or no start". They do not recognize in writing the danger of full power loss at highway speeds which is most often how it presents itself.

Power steering and/or braking may become inoperative or drasticly reduced performance when used at same time because power steering pump is also power brake pump and system does not have enough pressure or flow capacity to supply both steering and braking together. This could result in loss of control of vechicle.
