Rapid loss of oil from the transfer case, Oil was everywhere. Now I have vibration, wooing sound and hard down shifts from a failing transfer case.. The dealership refuse to replace it because they cleaned the area and it did not leak oil again. Probably, because there's no more oil left in it to leak.This is unacceptable.

My Acura was not sending power to the rear wheels. The car was driving as if it was front wheel drive only. I feel that the safety of not knowing your vehicle is not acting as they all-wheel-drive vehicle when it’s supposed to an impact safety because the vehicle would not be able to handle as it was intended to. After inspection from the Mechanic shop, the failure was deemed to be the internal lines of the transmission that would connect with the transfer case were stripped. Because of that, there was no power being sensor to the transfer case that will then send power to the rear differential to the rear wheels. There were no warning lights that show that the car is not sending power to the back wheel wheels. The situation that happened at realize that this problem has occurred, was when the front of my vehicle was stuck in snow and the car was unable to get out even when the back wheels were on solid floor.

The component that failed or malfunctioned was the transmission and transfer case on my 2022 Acura TLX type S at 45K miles. I was driving the car on the street and the car was shaking and stuttering violently and at certain points it would not move requiring a tow. The problem was confirmed by the dealership to be the transmission. And inspected by the manufacturer (Acura) there were no warning, lights, messages or other symptoms prior to failure. They started appearing around 45,000 miles.

The vehicles AWD system has prematurely failed as confirmed by the car dealership Acura of Pembroke Pines that I have taken it to. The lack of traction to the rear wheels causes excessive torque steering and constant engaging of the VSA system if the road is even remotely wet and the vehicle is under anything more than mid level acceleration. There are several Acura TLX Type-S trim vehicles that are being reported to have this common issue and Acura / Honda is keeping this quiet and replacing the prematurely failing transmission and transfer cases with what I fear are the same faulty parts instead of properly developing a revised updated part that will properly correct the issue. An AWD system is meant to give the driver confidence on the road and premature failure under slippery road conditions be it rain or snow is putting peoples lives in jeopardy.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
