Other Fuel System Tank Assembly problems of the 2014 Chevrolet Silverado 1500

I've had to get a new paint job because clear coat was coming off. Egnition switch locked up. Check engine light has come on multiple times I take it to the dealership and they say nothing is wrong with it. But tell me I can't let it get below a half tank of gas. Back axles lock up. And seat belts lock when going about 50 miles per hour. And the air condenser cought on fire. Now when I take it to the dealership they say they can not diagnose the problem. I have spent around $6000 in repairs.

When fueling vehicle, the pump stops continuously, as the handle shuts off as fuel will not flow into tank. Fuel is unable to flow into tank, so handle shuts off. You have to fuel at only a trickle. You spend twenty minutes to try and fill the vehicle. If the system is for vapor control it has failed because of poor design. You spend seven times more time,, standing around playing with the fueling handle to get some fuel into the system, than a similar vehicle next to you.
