Took my 17 in last week. They replaced the sending unit in the tank, they said the part was on backorder but had some in stock. ran two tanks of fuel so far and it is working as it should now.
Hello, just wondering if anyone has an update on this problem. I have a 2017 Silverado that only reads 3/4 full when I fill it up then it slowly moves to full. It does this intermittently and sometimes does not go to full tank. Thanks for any updates. I will be taking it to the dealer soon.
