2021 Acura TLX Type S: complete transmission failure

Filed Dec 2, 2025 · Engine · FL

My 2021 TLX Type S front wheels started to spin upon acceleration at 44K miles. I immediately scheduled an appt for the dealership. Was informed I needed a new Transfer Case Unit, as the splines were shredded. With this, I also had to replace the transmission. All replaced and picked up today 12/2/2025

While driving normal, I heard a pop sound coming from the bottom of the car which resulted in my AWD not working. On acceleration the car would spin the front wheels and the traction light would light up. Took to dealer and they confirmed the transfer case and transmission failed and had to be replaced. The splines between both components had stripped.

The all-wheel-drive stops working and the car becomes front wheel drive only. There are no warning lights on. The only way you could tell is to jack the car up with all four wheels off the ground and put it in drive to see if all four wheels are spinning. Also the driveshaft should be turning out of the transfer case. The the roads are wet or with snow the front wheels brake free very easy and the traction light comes on, which is also sign. I took it to the dealer and they verified the issue. They said it needs a new transmission and transfer case because the splines on the output shift of the transmission strip out and also damage the splines on input shaft of the transfer case.

I would like to report a serious safety issue with the 2021 Acura TLX Type s. Recently in April 2024, while driving, I heard a loud pop from the vehicle, and it turned out that the transfer case had burst into the transmission. This failure has rendered the rear-wheel drive non-functional, resulting in severe oversteer. This oversteer is especially dangerous because the vehicle is now operating as front-wheel drive, which creates an unpredictable and hazardous driving experience. This issue could lead to a catastrophic transmission failure, particularly at highway speeds, posing a severe safety risk to me and other drivers. I have contacted the dealer about the problem, but they have refused to take any corrective action. I’ve also found that multiple other owners have reported similar issues with this model, highlighting a potential widespread problem with the transfer case and transmission interface. Given the safety risks associated with this failure, I urge the federal safety agency to investigate this defect and take appropriate action to ensure public safety.
