 First the windows sound that looks like a air leak. The engine and transmission sound awful for a new car. You can hear all the noise as the vehicle change gears. My dashboard lights go intermittent from time to time. The breaks cry noisy . When you are in cruise control the vehicle calculates the front vehicle speed and slow you down. If the front vehicle change line the Toyota accelerates suddenly but if the front vehicle was close to another the speed safety control delay too much to kick in again making the vehicle unsafe. The 4cyl are a lot different from the 6 cyl. They looks the same but they are not.I can reflect more problems but at this point i feel sorry for myself to buy this peace of bran new jub k..
