2021 ACURA TLX Suspension Problems

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 perspective, if I continued to drive the car I could have experienced a malfunction in the braking system which could have led to brake failure, failure of safety features, or a car stall.

While using the Air Conditioner in Comfort Mode Suspension settings on my Advanced SHAWD model, the front suspension intermittently squeaks and creaks. It is very audible in the colder months or after it rains.

The contact owns a 2021 Acura TLX. The contact stated that while driving over a bump in the roadway, there was a squeaky metallic sound coming from the front passenger’s side suspension. The cause of the failure was not yet determined, and the vehicle was not yet repaired. The manufacturer and local dealer were notified of the failure and advised the contact to have the vehicle diagnosed. The failure mileage was 91,000.

The transfer case blows up and which causes the all-wheel-drive system of the car to go away and the car becomes from wheel drive which changes the way the car drives and makes it very dangerous. The car has a lot of oversteer and this is very dangerous to highway roads.

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...
