Vehicle was on 1/8 of a tank,I tried to fill, it would only take on 5 gallons of fuel, gas gauge read full. Reported to dealer, there is a �bulletin� on the vehicle, fuel tank was replaced. After successfully filling tank 3 times, it happened again, returned vehicle to dealer, they could not replicate, brought vehicle home, dealer was able to fill tank with approx 13 gallons, I ran it to 1/8 of a tank tried to fill and it continues to only fill with 2-6 gallons, and record on the gauge a full tank. Very difficult to tell how much fuel is on board. Meeting with GMC district rep 11/19/2020. They suggested I drive it till it runs out of fuel as to see what the gauge reads! really? help please! I have photos of the pumps and dashboard to record and time stamp. I need help please! the first occurrence was September 28, 2020 , second occurrence October 16,2020 and third was November 15,2020. The vehicle was returned to the dealer on October 16, they tried to replicate with no luck, vehicle was returned to me November 11,2020! 26 days later. Help!.
