My 05 Sequoia only gets 12 MPG in the city and it has been like this for the 12K miles that I have owned it since it was brand new. I knew it would not get good mileage but like someone else said technology should have this thing getting better mileage than 12.
I love everthing else about the truck ; well except for the fact the back window stopped working and I have to bring it in to get fixed.
