 I own this SUV since Feb 2017. I had own 2010 highlander and decided to go for new. Worst decision. The performance is extremely poor on 8 speed gear box. The vehicle is hesitant to start or accelerate from a stop signal, people will overtake you and look you like what the f*** you are doing. RPM goes all the way to 5000 still the car doesn't move. I heard about a new software released from Toyota for this issue and updated it, slight improvement but I hate it. Vehicle is stalling at lower gear and too quick gear change. I was really surprised Toyota is releasing a car with such worst transmission. I like everything else about this car, but whats the use when the heart of the vehicle is a failure. I am thinking of selling this car. I definitely think, the transmission issue would be really slow down highlander sales. Please be aware before you purchase.....
