My car has suffered a well known issue in the 21-25 Acura TLX community. At 71,000 miles my transfer case splines stripped also with the transmission splines. Resulting in me having to pay out of pocket to replace both the transmission and transfer case. I’m really hoping Acura does a recall for this issue. I really like this car and don’t want to have to replace them again. Like I mentioned before. I’m in a Facebook tlx group and people are constantly posting about theirs blowing.

Adaptive Damper System error on dashboard. Took the car to the dealer and they confirmed two issues. Codes C1646-14 and C1647-14 indicating the stroke sensor has lower limit abnormality. Dealer recommended replacing both rear shocks due to over extension. Once shocks were replaced, codes returned. During further investigation, corrosion was found in the stroke sensor wiring harness. Harness is the root cause of the issue. Car is available at the dealer for inspection if necessary. From a safety

This 2021 Acura TLX Type-S has experienced a complete failure of the transfer case after approximately 40,000 miles of use. This unfortunately is a known issue on the online forums for this vehicle in model years 2021-2023. I have a video inspection performed by the local dealership proving this. The only warning is a one-time loud boom when accelerating and a leaking from the transfer case of fluid thereafter. There is no safety issue best I can tell, however the car only performs in front dri

While driving my 2021 Acura TLX Type S, I began losing traction frequently during normal daily driving, especially when turning corners or accelerating from a stop sign or stop light. At first, I believed the issue was related to my tires, so I replaced them, but the same problem continued. After researching online, I discovered that transfer case failures are a known issue on these vehicles, affecting both new and used models. Currently, my vehicle is at the dealership, but they were unaware of

- The transfer case failed causing the AWD system to stop working -It is a safety concern because you may lose control since no power is going to rear wheels, especially in inclement weather that we receive in the northeast. -Yes the problem has been confirmed by dealership by putting car on lift and seeing that no power is being sent to the rear wheels. -There are no warning lights or any signs, you just hear a loud bang while driving and lost of traction while accelerating

While performing a right turn, under normal acceleration a loud "pop/clunk" occurred. I immediately pulled into a parking lot as the vehicle was still able to drive. The vehicle runs as normal, no leaks of any kind present. Nothing visibly broken. Afterwards, I was able to determine with the vehicle suspended off of the ground, I am getting power only to the front wheels. Utilizing google, it's easy to see that this has become a MASSIVE issue on this particular model TLX Type S. The vehicle w

The wipers come on by themselves and do not turn off. The engine may or may not start with the key fob nearby. All the dash warning lights come on with warnings about the brake system, the transmission, the steering, the adaptive cruise control all reporting a problem. The vehicle goes to limp mode and throttle response is severely reduced. There is some sort of water leak which is shorting out or causing the BCM or body control module to act erratically due to water from rain getting into the
