Power take off unit on the TLX TYPE-Ss are stripping at the splines where the drive shaft and PTU meet. This disables the cars AWD system without triggering any codes, giving drivers false confidence to drive in low traction environments which may lead to accidents. The car retains FWD function but struggles to gain grip on the road at all speeds because it is an AWD designed platform. The dealership of Spreen Acura diagnosed my car and confirmed that the PTU fluid was previously leaking and had metal shavings. They also confirmed that the car was now FWD and struggled with getting traction with acceleration. This is a problem as it ds not show any indication during failure, there could be many people with failed PTUs who are unaware and driving daily. With rainy season coming up, this could pose a big risk as drivers with these cars will think their TYPE-S is AWD and my end up getting into accidents when driving unaware.
