Purchased a 2010 rav4 v6 5 speed auto transmission, at 8000 miles it developed a transaxle whine at 40 mph. Took it back to the dealer, was told nothing was wrong with it. I was. told I hear it because I have a hearing aid. I called Toyota customer service, was told "take back to the dealer".Was never told of any memos on this problem. Took it back to the dealer and had the Transmission man take it for a ride with me. He heard the whine abd went back to the dealership. Pluged a laptop into the computer and said see nothing wrong with it, a computer will not show a whine if trany is shifting collectly. Called Toyota again, was told the same thing"TAKE IT BACK TO THE DEALER".Was never told yet of any memo to the dealer. Iwas discussed with the rav4 because of this whine which had gotten worse. Finally traded it off. While on vacation this summer I stopped at a Toyota dealer up north and asked if they ever had any problems with awhine in the rav4.Showed me memo # T-SB-0192-10 that showed about a whine in the transmissions of 2006-2010 rav4s, dated July 15 2010.I was angry because I got rid of a good vehicle that should have been fixed, but they lied to me about it. The transmission man should be fired for his lyies. Spoke with the owner of Phillips Toyota, He said he would look into it and call me. Haven't heard from him since. Called Toyota and advised I was lied to by the dealer and why I was not told there was a memo to the dealers to fix the whine. I was told by some idiot there"WE DIDN'T TELL YOU TO GET RID OF IT".Don't go to this dealer with a problem, you to may be lied too!
