Other Fuel System Tank Filling/charging problems of the 2021 Toyota Highlander

I reported my gas tank not filling past 12. 9 gallons of gasoline on numerous fill ups on my new 2021 Highlander hybrid platinum to Toyota service department. The Highlander on invoice says it's a 17 gallon tank capacity. Toyota service depart refilled my empty tank to12. 6 gallons verifying my complaint. The service advisor informed me they notified Toyota and Toyota responded in saying they are aware of the issue and there's nothing todo. The Toyota service advisor inform me until there is enough complaints then Toyota would issue a recall ## #vpic# 1 - check digit (9th position) does not calculate properly; 4 - VIN corrected, error in one position only (indicated by ! in suggested VIN), multiple matches found; 14 - unable to provide information for some of the characters in the VIN, based on the manufacturer submission. #vpic#.

This is not a safety issue per se but one of false advertising. Toyota advertises the range of my hybrid Highlander as 600 miles on 17. 1 gal tank at 35 mpg. I do get 35 mpg (which is quite commendable for a vehicle this size) but I cannot fill the fuel tank more than 12-13 gal even when nearly bone-dry empty. In turn I cannot drive any further than 450 miles without filling up. Something is wrong with either the design of fuel tank such that not all the fuel can be accessed or the design of the fuel filler hose such that one cannot fill the tank completely. Another option is perhaps the fuel tank is not truly 17. 1 gallons as documented. Toyota should not advertise a range of 600 miles when this is not realistic even when achieving 35 mpg.
