 This is my 4th RAV 4 and Loved them so much until the 2016 model drastically let me down along with Toyota Motor Corporation.  I was in joy as I left the dealer lot with my shiny new RAV and loved everything about it , driving it around for a week or so and the clock around 500 miles I noticed this horrible ear piercing whine coming from the Transmission ? I immediately took her back to the dealer and gave them all the specifics of what I was hearing and concerned a catastrophic failure was to come ! They had the vehicle all day test driving and confirming the whine was present at all the specific areas I pointed out - a high pitch whine right before shifting to 2nd and 3rd as well as a horrible drone type whine between 40 and 50 mph and again on deceleration from 65 to 60 mph ??? They also confirmed it on another new 2017 on their lot that they took for a test drive ? I was happy the dealership took the time to look into this and confirmed this horrible noise but as of now it is an open case with Toyota Motor Corp. and doesn't seem to be going anywhere as they pretty much are telling me to live with it. I own this vehicle less than a month and hate it with a passion as I feel like I'm driving a city bus whining my way down the road ! I am disgusted with Toyota's QC and how I read of so many others with the same issue.......my 2013 and 2015 have the same engine and tranny and are so smooth and quiet, so how can they say this can be normal ? This will be my last Toyota if I can get rid of it without taking too much of a beating. Also keep in mind a tranny replacement for this vehicle requires the entire engine to be dropped out from the bottom which also means tearing apart the entire front suspension system.  So think twice if thinking of purchasing a 2016 or 2017 RAV4 and take it for a long long test drive before handing over a dime.
