Power Train · reported May 31, 2026
While accelerating from a stop, I heard a loud bang from the drivetrain area and initially believed another vehicle had struck the rear of my car. After checking my surroundings, I realized there had been no collision. Immediately after the incident, the vehicle lost power delivery to the rear wheels. The vehicle is designed as an all-wheel-drive performance sedan, and the sudden loss of rear-wheel power significantly changed the way the vehicle handled. The vehicle became effectively front-wheel drive without warning, causing all engine power to be directed through the front wheels. This…

The All Wheel Drive (AWD) system of the vehicle became partially inoperable after hearing a loud bang under normal vehicle acceleration some time in early 2025. The vehicle did not trigger or display any warnings stored in the onboard computer or on the dash display that the AWD system had any faults or issues. Had this system failed during an emergency situation involving hazardous or dangerous driving conditions like snow, ice, heavy rain, it could have caused me to not have improved capable vehicle handling. The vehicle's ability to distribute power evenly to all 4 wheels was hindered and…

The transfer case in my Acura TLX Type S failed due to the internal splines stripping at approximately 57,600 miles. I heard a loud bang while attempting to maneuver out of a parking spot that was covered in snow. When this occurred, the transfer case was no longer able to transfer power to the rear wheels, causing the all-wheel-drive system to stop functioning. As a result, the vehicle effectively operated as front-wheel drive only. The most concerning part of this failure is that the vehicle provided no warning whatsoever to the driver. There were no dashboard alerts, drivetrain warnings…

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 drive mode once the transfer case quits working. The issue is due to weak splines within the transfer…
Engine · reported Dec 2, 2025
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
