Other Fuel System Tank Mounting problems of the 2018 Chevrolet Equinox

Vehicle fuel gauge does not accurately register the amount of fuel in fuel tank. Will not register "full" even when fuel is flowing out of filler tube. When gauge begins to register "empty" and distance remaining approaches "0", it take less than 10 gallons to fill the 15 gallon tank. This creates the situation where the driver potentially drives the vehicle on remaining fuel and then runs out because driver is unable to determine actual quantity of fuel remaining. This has potential to create a hazardous situation if it occurs on a congested freeway/interstate, or a dire situation if it occurs in an unpopulated area removed from available gas stations. It creates an uncertain situation here in west texas where there are large stretches of highway between communities. Chevrolet/gm has been aware of the problem since July 2017 and has stated that the fuel tank must be dropped and fuel sensor reseated or replaced, yet they are doing nothing to act upon that corrective action. I have opened two customer cases with Chevrolet in an attempt to resolve, and each time the cases are closed with comment that ". . . Engineers are working. . . . ".
