We have had a Highlander Hybrid 17 months. It gets around 33 MPG average. Sometimes less if it's mostly highway driving.
Washington charges us an extra $225 per year for license because it supposedly doesn't use as much fuel. But it's really because the state can charge what the want.
They say you can carry 7 people but they don't tell you 3 of those people better be small kids and it would be best if 5 of them were kids. The back seats are small. The center seats do not fold flat so you lose rear cargo space.
My cousin bought a Vensa hybrid and she gets better mileage, around 40 MPG.
Toyotas have an App that will connect your phone to your car. You can not unlock the doors with a remote, you have to use your phone. It also has navigation assistance, and navigation real time update. All free for the first year. Then if you want to remotely unlock the doors you have to pay $4 per month, navigation assistance is $8 a month and real time navigation updates are another $8 a month.
The voice command button to make calls or program the navigation work well unless you have a USB thumb drive installed then it does NOT work. I had to figure that out myself because the dealer couldn't. I took it in 5 times for them to try to correct the problem.
Also the rear seat shakes and makes a noise and the dealer told my wife "yea they do that some times". $50,000 and they do that sometimes is Not acceptable but they still have not fixed that.
The lane control and corner centering drove me nuts till I figured out how to turn them off. Plus they don't work all that well so I keep them turned off.
All that said I would not buy another one. It's a nice looking vehicle and drives well but the aggravation with the small things and the gas mileage would make me look elsewhere.
