I was having this issue on my 2019 certified used RAV4 Hybrid I bought in Feb 2021. From low indicator to the fuel pump click, I could add about 8-9 gallons. My local dealer had me bring in the RAV4 on a full tank and they checked the actual level (I guess it wasn't enough to check the vin.) They agreed that my car was included in the "support program". It took about 3 weeks for the parts to come in. They replaced the fuel suction gasket, fuel sender gauge assy and fuel tank sub-assy. Took most of a day BUT what a difference. I filled it from about 1/4 tank to pump click, it took 11.5 gallons. My DTE is 585 mi . I think my best previous DTE was 430 mi. So yea, the fix seems to have resolved the issue.
