2023 Acura TLX Type S Transmission and drivetrain Problems

“Lost power to rear wheels. AWD system failure. I was denied repair at my local dealership as they insisted the car was fine. I told them I had no awd they didn’t believe me. I was then forced to trade my car into them for a massive $$ loss becuase i feared for my safety driving a fwd car in the winter. I don’t know who owns the car now. I actually have a video of it happening. I can send you it if you work with me. Thanks.”

“1. Transfer Case-SH-AWD failure-> No, it was recently replaced at the dealership at no cost. 2. Failure with the AWD system would cause me to be in FWD, only causing failure in steering input, especially in turns. 3. The car was put onto the lift and attempted to spin all 4 wheels, only the front 2 spun. Also, they noticed a seal failure/leak from the Transfercase/Transmission. 4. Acura Technicians recommended the replacement after spotting my concern and pointing out the exact issue 5. …”

“While making a right turn from a stop the car made a bang sound followed by grinding upon acceleration. I took my 23 TLX type S to a local Dunn Tire and asked them to put it on the lift.

The car is driving without error lights but feels different while corning. It's very concerning that the car has 41k miles on it and is well taken care of. …”

“Short Description Transmission-to-PTU splines, causing AWD loss and requiring full transfer case and transmission replacement. Summary This drivetrain failure poses an unreasonable safety risk due to the sudden loss of AWD capability, lack of alerts, and resulting instability. My experience is consistent with dozens of documented cases and matches the mechanical fault pattern already under federal review. Given the potential for severe loss of vehicle control, a full investigation and corrective action (including a recall) is necessary. …”

“Transfer case documented as leaking on 3-22-2025/ 35,846 Miles while doing regular oil change in my driveway. Brought to the dealership and they confirmed the transfer case needed to be replaced. If the transfer case went during operation, it could have lead to a dangerous situation with loss of power and control to the rear wheels. Problem was confirmed after dealership performed visual inspection. Component was not inspected by police, insurance, or others. No warning lamps, just accumulating liquid on the under-body panels and seeping from the gasket. …”
