Transfer case failure, leakage, discovered after warranty expired. Took vehicle in describing seeming loss of AWD and tech informed me it was “normal” I Later discovered, during an oil change, a leak From the transmission or transfer case that covered the lower skid plate, which looking up, was directly related to a known failure of the Type S’s transfer case/Transmission causing a loss of traction to the rear wheels.

The transfer case splines sheared off in the transmission. The car is safe to drive but went from AWD to FWD as there is now no power being transmitted through the transfer case to the rear wheels. The dealership confirmed the issue was the transfer case by lifting the car and seeing if the rear wheels were getting power. They then tore down the transmission and found the splines were all gone from the transfer case. The component was not inspected by the manufacturer, police, insurance, or anyone else. There were no warnings or symptoms to the problem before the failure.

We have a 2022 Acura TLX Type S and it has started to show an errors - Adaptive Damper System Problem. From what I can gather from reviewing articles on the Internet is that this problem is caused because of poor wiring design by Honda / Acura, which is causing speed sensors electronics to erode. There are also articles that Honda /Acura is aware of this problem and is currently gathering data. Our concern is that in Michigan, if you have these problems, specially during winter when the roads are icy - if your drive type is stuck in the wrong mode - That can be a safety hazard. Example -The adaptive damper system can cause the automobile to be stuck in sports mode on an icy road, making it dangerous to drive............ Further, consumers are aware that this is a fault of the manufacturer, in the way the wiring harness is routed within the automobiles chassis. This poor design exposes the electronics to unwanted elements from road, snow, salt, dirt etc. It is also reported that this wiring harness is an expensive item to fix, hence Acura is reluctant in taking the necessary effort in resolving this very known issue. Consumers pay a lot for these vehicles for their quality - If this is a known issue , Acura should take care of it and not force the consumers to drive acuras with potential safety issues.

Accelerated and heard a loud noise and felt like I had driven through wood and one got stocked to the whelle. There was a lot of traffic so I was driving slow. The noice I heard was like something was stuck inside the wheel, like it was grinding. Dealer diagnosed a bad transfer case and transmission and they replaced both under warranty.

Was changing the oil on my car and noticed grease running out from between the transfer case and transmission and also fluid build up on the transfer case higher up a little below the driveshaft. The car has 41k miles on it, there should be no leaks. My concern is the transfer case/transmission spline failure issue.
