Need your help guys. I just bought the latest RAV4 Standard 4x2. A day or two after I got the car I noticed some unusual vibration on the car whenever it shifted from 2nd gear and up. It usually gets out when you press on the gas pedal lightly and accelerate slow. It vibrates like as if the car is running through those small road white painted strips but the vibration is not as elaborate. I already made a complaint and the car was serviced by Toyota for 2 days. According to the SA, they just made some tightening on the car and they made a road test and it's all good. Got the car today and still the vibrations are there. I made a complaint again and they told me to bring it back again. Is this grounds for replacement? According to the Sales Agent they don't replace brand new units but fix it. I told them I can''t have a brand new car going in and out of repair. Any inputs on what to do will be highly appreciated. Thank you.
