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.

When traveling on a gravel road or driving on some paved roads, the steering wheel of my truck pulls back and forth in my hand and grabs on bumps. This summer the problem was so severe I got under the truck to see what may be causing the movement. I found out there was no steering stabilizer shock installed on the truck. The brackets to house the stabilizer shock are there, but the steering stabilizer shock itself is not there. I took the truck to the dealer and was told by dealer that the truck doesn't come with a steering stabilizer shock. He didn't seem to know why the trucks don't come with the stabilizer shock, but there is an after-market part that the customer can order and they will install for about $200. I contacted General Motors to ask for an explanation as to why such an important steering component was not provided in the truck. Ramon from customer service called me to explain that the truck was "designed" without the steering stabilizer shock. There were brackets to house the shock included from the factory and indeed there is an after-market shock I could buy and have installed at my own expense. I argued that this was a safety issue and felt that this was a defective factory issue. The truck should come with the shock and it is not safe to drive under certain conditions without it. I don't believe people who are buying the new trucks are even aware that the steering stabilizer shock is missing. It will be just a matter of time before there is an accident caused by stable steering failure. I would like it put on record that if any injuries or accidents are caused by this "design" flaw, there should be recourse put directly upon the shoulders of General Motors who delivered the trucks without this important part, who refuses to put the part on when the customer finds out, and does not even tell the customer that the part is not there.

New vehicle front end suspension began to randomly violently shake at different speeds (once @ 55 mph & once @ 70 mph). The shaking was so bad that the driver could barley hold the wheel straight to avoid losing control & crashing. While this was happening the vehicle 4 wd light was blinking despite the fact that the vehicle was in 2 wd. Once driver was able to pull over he inspected the outside of the vehicle to find no mechanical issues (no flat tires, things in the wheels, etc...). driver then began driving again & the vehicle was fine as if nothing happened. Driver called onstar & they stated there were no fault codes in the system. Several days later the same thing happened while driving at 70 mph. This time the driver nearly got into a roll over accident. He was able to get the vehicle to the side of the road. Upon inspection there were again no mechanical issues. Owner drove to dealer & was told to bring back the next day. Owner inquired if vehicle was safe to drive & was told "I hope so" by the service technician. GM customer care was called & stated they were not aware of any issues with the 2011 hd vehicles. Owner took vehicle to dealer next morning & several hours later was called & told it was mud in wheels (not possible since the first time it happened there was no mud). Owners son then looked on internet to see many people having the same issue in this model year vehicle. The son then found that a tsb was issued by GM to all dealers for a sticky break pedal that when stuck (even though it appears visually to not be stuck) will at random times cause the ABS to activate violently. Tsb# pit5037B. Dealer was then told by owner about the tsb & dealer was not aware of tsb. Repair was performed & the vehicle has not shook since. Owner was suppose to be pulling a 30 ft 5th wheel with a 15 ft trailer attached to it (45 ft. Total). If they had been they likely would have been in major accident with possible loss of life due to the sway it causes when it occurs.
