2017 GMC Sierra just ran out of warranty in Oct. Right around Thanksgiving I notice that the fuel fill flap was staying open after putting fuel in period it now gapes open and the whole mechanism needs to be replaced. Estimate I just got less than 10 minutes ago was $530. What!?!?! For a flap dohickey!?!?! I have also had the issue where the fuel pump shuts off while filling. About a 1/2 gallon will be dispensed and then it will click off and I have to go start the pump again. I saw both of these complaints already listed so it’s not just me. But I wanna know where to get the $338 estimate for this flapper thing because I’d really like to save 200 bucks.

Capless fuel fill is now a much more common feature than in years past, when it was a rarity. According to research performed by
GM Authority, GM currently offers capless fuel fill on 26 vehicles, including the new Blazer, third-generation Equinox, Corvette, Camaro, Silverado, and Sierra, as well as most Buick, Cadillac, and GMC models.
As the capless fueling technology becomes more commonplace and is used more and more by customers, some have begun voicing disapproval of the convenience feature. Stories of various complications can be found on the web, including frozen winter woes, where the flaps are frozen shut.
