367-horsepower 6.0L V8 4-speed automatic 4WD w/low range

29760 mi Truck runs out with DIC showing 68 km DTE, and fuel guage shows 1/8 tank left. Dealer replaced fuel sensor in tank. Now truck runs out of fuel when DTE says 105 KM DTE. Problem is worse now, Fuel gauage over 1/8 tank left, low fuel light does not come on. 
32240 mi Engine oil cooler lines leaking at crimp Hose-tube near radiator. Dealer says not leaking bad enough. I am going to call GM and complain. Vehicle runs out of fuel above 1/8 tank on gauge and 76L used on DIC. Worse now than before fuel level sensor was changed. Dealer says Diagnostics shows 60% and fuel gauge says 60% so must be ok. I will take truck to them when about to run out.
