My 2009 Toyota RAV4 V6 auto has a whine in the transmission final drive that is evident between 40 and 100km/h, but loudest at lower speeds and under light load. Two auto trans specialists, a Toyota dealer Master Technician and three independent automotive technicians have diagnosed it and all consider it unacceptable. A Toyota Australia representative who drove the vehicle stated that the whine was a normal operational noise; even though other qualified people recommended that the source of the noise should be rectified. Toyota stands behind it representative and will not do anything. Do you have any suggestions?
Get all of the people who say it should be rectified to give you their views in writing and request a meeting with Toyota through the dealer and submit your claim directly. It would seem on the surface that you have a good claim. Should that fail to achieve a satisfactory outcome your only course of action would be to seek a solution through consumer affairs.
