While making a left turn from an on-ramp, I heard a loud crunch from the drivetrain and experienced a momentary loss of power. Immediately afterward, the front tires began spinning under acceleration. I realized the vehicle was no longer sending power to the rear wheels and had effectively lost its all-wheel-drive capability.  The instrument display continued to indicate that power was being sent to the rear wheels even though the rear wheels were not receiving power. This gave an inaccurate indication of the vehicleâs operating condition.  The vehicle was inspected by an authorized Acura dealer. The dealer confirmed that the splines between the transmission and the front power takeoff unit had stripped. The transmission/front differential assembly and power takeoff unit were replaced under warranty at approximately 52,280 miles.  The dealer stated that this is a problem they have been seeing on the MDX Type S and also commented on the number of revisions that have been made to the power takeoff unit. The replacement unit installed was part number 29000-61E-070.  The failure created a safety concern because it caused a momentary loss of propulsion while turning into traffic, followed by unexpected front-wheel spin and loss of all-wheel drive. There were no warning lights or advance warning before the loud crunch and loss of power. The failed components were replaced by the dealer; whether they remain available for inspection is unknown.

ACURA MDX TYPE S 2023 POWER TRAIN

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 19000.00 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.

Transfer case became defective and fluids started mixing in with it and in the result of all of that I needed a new transmission as well
