Strong exhaust and or raw fuel smells inside cab and around outside of vehicle engine bay. Especially noticeable when vehicle is regenerating. Smoke billowing out from under right side of hood. A clear liquid and a black liquid running down exhaust pipe from turbocharger exhaust exit. Noticeable leakage on floor under vehicle. This is a fire hazard that is not being diagnosed, repaired or tested correctly. This vehicle has been to GM dealers three times to address these problems.

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.
