 We purchased a new highlander in August of 2017. We have 6k in miles and we brought up it in for maintenance and it is leaking oil. Toyota service can’t figure out why and Toyota engineers don’t know so they said flush it and drive it and see what happens.  We do not want the vehicle and have left it there. I have 2 young children and am not driving a car with engine issues. We have a Toyota case manager and they won’t do anything.  My whole family is Toyota owners right now we have 6 and have been loyal. I’ve lost all faith that Toyota will do the right thing and my mission will be to make sure all customers know how poor an experience I’ve had unless this is remedy. The only remedy that works is a replacement. Im a business owner and when you screw up you make it right.
