Problem Description and Possible Solution
The fuel gauge may be slow to register, fail to read full when the gas tank is actually full, or read inaccurately. Our technicians tell us there is a redesigned fuel tank sender unit to remedy this problem.
Average mileage: 96,713 (11,800–180,000)

We fill up the 2005 QX56 and would only show 3/4 full for about 10 minutes and then finally would show full. Thought this was odd and now realize there is a recall for this issue. We have had so many electrical issue with this vehicle. Surprised they are still certified to be allowed on our roads lol. The brake issues are horrible.
We purchased this vehicle from a family member. It was four years old and had 99,000 miles on it. Since we have had it the gas tank has never registered as "full". It will only hold a maximum of 19 gallons when it is completely empty . I'm wondering if it doesn't if it reads empty when it's really still has 1/4 of a tank. ( i've never been brave enough to test the theory :). Anyways not a complete dealbreaker...it's just very annoying when traveling when you have to fill up every 250 miles considering the gas mileage is NOT awesome so that 19 gallons of gas goes quickly!
Gauge would read half full even though we would fill to full, we have 2year warranty , we told the dealership and they replaced the whole panel. Due to some faulty wiring or something along those lines
