While making a left turn into a parking lot my car exhibited a loud bang noise. It felt as if the car had been hit from the rear. While applying the gas the car jerked and popped in the rear. I had the car towed to a dealership where I was informed the transfer case had " Destroyed itself". The gears broke apart internally. I was also informed that the transmission power take off was destroyed.The car only has 87000 miles on it and has been serviced at recommended intervals. The dealership quoted $19000 dollars to repair. The car was out of Acura"s powertrain warranty. I had a third party warranty that I used to repair the car. I was 5 hours away from home when this occurred. I was without a car for 4 weeks. I believe that this is a manufacture problem and is dangerous. There were no warning lights before or after the event. The car has been repaired. I have a video of the dealerships diagnosis of the transfer case and transmission failure.

I hear a high-pitched whistle when I the speed reaches around 57-63MPH. I've taken it to the dealer a couple of times, and they said it's normal. I am really disappointed that Acura didn't fix it...

The automatic transmission on the vehicle failed without warning. Vehicle was driven on the highway without issues; exited highway to a city street, stopped at a stop light, and turned onto another street. Upon turn onto another street, transmission did not upshift as it should; it was noticed the engine was revving high, but transmission did not shift. Tried to manually shift, with no luck. There were no warning lights or messages present at any time. Vehicle was stopped in a safe area and turned off, restarted, and tried again. Transmission still would not shift correctly; when it tried to shift, it would clunk, and it sounded like something dragging under the vehicle. Drove vehicle home and parked it. Later when transmission was shifted into gear, it did not move, and made a terrible clunking noise, then a squealing sound. Called dealer and had vehicle towed in for inspection. After inspection, manufacturer replaced failed transmission under warranty. Per dealer rep, transmission failed, and registered two internal codes, one for incorrect gear ratio, and other for torque converter issue. While the codes registered internal, unfortunately there were no warnings issued to driver. Safety was put at risk because if the failure happened while on the highway three miles earlier, there was no warning to driver who was driving in heavy traffic, and they may have been involved in an accident. The only reason the driver was aware of the issue was because they could hear the engine revving high, and they pulled over to inspect. A less experienced driver may not notice the same issues. Additionally, it's concerning that transmission codes were stored internally but did not trip any transmission issues or loss of power warning; this could prevent drivers from noticing issues prior to failure. Lastly, the vehicle health report we received from Acura on 12/31 (and states as of 12/12, day after failure), stated there are no transmission issues present.
