Transmission and transfer case failure. Causing the loss of power to the rear wheels. Reducing the traction and stability of the vehicle.
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. They raised all tires off the ground, started the car, and accelerated. Only the front wheels spun. This is the exact scenario lots of consumers have reported with this model when the transfer case splines break off the shaft. 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. I drive it in winter so AWD is a huge reason I choose it. I have an appointment with my local Acura dealership but its over a week away. I asked to have a tech contact me back to ensure driving it more won't case future issues but they never followed up.
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.
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. Symptoms Sudden AWD loss Loud bang or grinding Only front wheels receiving power No warning lights Safety risks Loss of directional stability Wheel spin under acceleration Hazard in inclement weather Cost & extent of repairs Many cases require complete drivetrain replacement costing $13k–$19k. Prevalence 137k+ vehicles, NHTSA DP26‑001 currently open.
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. No lights or warning since the failure happened I had no idea of how bad the issue was until an Acura Technician brought it up. 5(c). I did notice a difference in driving feel i.e jerking in low gear and a leak on the floor, but thought it was just excess oil from oil changes. Confirmed by the tech, it was not when I asked them.
Transfer case
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. The transfer case was replaced on 11APR2025 with the same part number: 29000-5YK-060. I asked if this would happen again since there was no revision to the part number, the dealership was unable to reply.
New car three months old. Did not include spare tire. Tried ordering one and told it was backordered. Told Acura considers spares accessories. I don’t. Now have new car with no spare , no tools to change flat tire, no Jack. No help from Acura other than they’ll let me know when the spare kit is available. I consider this a potentially serious safety problem.
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.
