While driving on the freeway, exiting to an off-ramp, truck lost power steering and brakes simultaneously, without any prior indications of mechanical trouble. Chevrolet currently shows no recall on this vehicle. Fortunately traffic was light and a collision was avoided. Why would one critical system's pump--power steering--be used to drive a second critical system's pump--hydrobooster?

I have a 2011 Chevy Silverado with a fuel gauge problem. While driving downhill, my fuel gauge light just comes on and the fuel gauge goes down to empty. The vehicle then stalls losing all power and control of the vehicle (brakes, steering). As I reach the bottom of the hill, I have to place the vehicle in park and it starts right back up but the fuel gauge stays at empty. I had the vehicle serviced at a GM dealership and it was stated by the tech that vehicle is working as designed. This was also confirmed by GM engineering department. If I recall, the fuel pump is placed more toward the back of truck and while driving downhill gas moves towards front of tank giving the fuel sensor a false reading. I'm no engineer but I had a 2009 Silverado and never came across this problem. This is a big vehicle and I believe this poses a great safety risk to myself and family as well as the public. Many times when the truck has lost all power steering and braking capability, myself or my family members who are driving have narrowly avoided accidents. GM tech and GM corporate said remedy is to keep more gas in vehicle. This is a continuous problem as at times in travel I may not keep my tank as full as required by GM.
