 Rear four wheel drive suspension making loud clunking noise when coming to stop from backing up or going forward. Dealer replaced both lower arms twice, swapped shocks and coil packs with no change in noise. District Toyota rep when  for ride with me and heard the noise as well. Stated that its the normal characteristic of this car and if enough people complain maybe Toyota will come up with a fix. This is unacceptable when you pay $45,000.00 for an SUV. Also the front drives seat is very uncomfortable as your left arm rests to low on the door hand rest. If they don't come up with a fix soon I will trade in for a Honda Pilot. I will never buy a Toyota again after this experience. Its been in the shop at least 8 times with no resolve. Just traded in for Honda Pilot because dealer and Toyota could not fix problem and said they do not have a fix. I will never buy a toyota again.
