Accelerated and heard a loud noise and felt like I had driven through wood and one got stocked to the whelle. There was a lot of traffic so I was driving slow. The noice I heard was like something was stuck inside the wheel, like it was grinding. Dealer diagnosed a bad transfer case and transmission and they replaced both under warranty.

Was changing the oil on my car and noticed grease running out from between the transfer case and transmission and also fluid build up on the transfer case higher up a little below the driveshaft. The car has 41k miles on it, there should be no leaks. My concern is the transfer case/transmission spline failure issue.

} I am submitting an update to my previous complaint. In my original complaint, I stated that the vehicle had not received transmission service. After reviewing my records, I confirmed that a transmission fluid service (drain and refill with inspection) was performed at an Acura dealership in July 2024. Despite this maintenance, the transmission still failed at approximately 84,000 miles. I am providing this update to ensure the complaint is accurate

I am reporting a transmission failure in my 2021 Acura TLX with approximately 84,300miles. While driving under normal conditions, after about 30 minutes on the road, I came to a stop at a red light. When I attempted to accelerate again, the vehicle would not shift out of first gear. The engine would rev, but the transmission failed to upshift. I also experienced a hard and abrupt engagement when shifting the vehicle into reverse. This issue occurred suddenly without warning and made the vehicle unsafe to operate in traffic, as I was unable to accelerate properly or maintain normal driving speed. The vehicle has been regularly serviced at an Acura dealership. At the time of the incident, the transmission fluid had not yet been replaced but had recently been recommended during a scheduled service visit. The vehicle is currently at an Acura dealership where I normally get the car serviced. The dealership has diagnosed the issue as an internal transmission failure and is recommending a transmission replacement.

POWER TRAIN
2021 Acura TLX A-Spec SH-AWD and my transmission is leaking from the seal between the transmission and the differential. Acura is not sure if they can cover it under warranty because I am slightly past the powertrain warranty even though they had my car about a week ago when it was just barely past that point and no one said anything about the leak on the transmission until I checked with a certified Acura mechanic somewhere else.This is not just some small problem because with fluid leaking and leaving it will eventually damage the transmission and the differential or even just make them completely give out. This can be gears grinding and overheating. It is not just a problem it is also a SAFETY HAZARD if this starts dripping onto the exhaust pipe or even on the road behind making traction a problem for someone behind. This needs to be under a recall not just warranty with how much I see this happening to these cars this is ridiculous we have to go through this.

The all wheel drive failed do to transfer case splines being sheered off between the transmission and transfer case. No warning lights are on to warn of the rear wheel tires not receiving power to them. I was not aware of this problem and this could have contributed to and accident, as I though the AWD was working, but it wasn't.

My vehicle was performing as expected, but there was a smell of burning oil or rubber. When I took the car into the dealership the found that the transmission was slipping and the transfer box was failing. In the video they sent of the initial inspection there is obvious brown sludge leaking from the transmission. I was told that a complete transmission and transfer case was required.

My vehicle has less then 35000 miles, I was doing a oil change when I noticed that my transfer cases has a slight oil residue from the bottom, which I suppose it’s just gonna get worse overtime, at this mileage I don’t think this is right that’s why I’m submitting this complaint.

I am submitting this complaint regarding a sudden and premature transfer case failure on my 2021 Acura TLX Type S equipped with Acura’s Super Handling All-Wheel Drive (SH-AWD) system. The failure occurred during normal driving conditions and without prior warning indicators. Based on my experience and numerous similar reports from other owners of this vehicle, this appears to be an ongoing and systemic issue that warrants formal investigation and recall consideration. While accelerating under normal road conditions, I heard a loud and distinct “pop” noise from underneath the vehicle. The sound was abrupt and mechanical in nature, as if an internal drivetrain component had failed. Immediately following the noise, the vehicle’s driving characteristics changed noticeably. Although the car continued to move forward and there were no immediate warning lights illuminated on the dashboard, the drivetrain behavior was clearly altered. After the incident, the vehicle began operating as though the majority of drivetrain load was being directed to the front wheels. The vehicle now feels significantly front-heavy during acceleration and general driving. There is a distinct change in weight transfer and torque delivery that was not present prior to the failure. The balance that is characteristic of a rear-biased SH-AWD performance system is no longer present. There were no grinding sounds, fluid leaks, or vibration at the time of failure. There were also no warning messages, check engine lights, AWD system warnings, or drivetrain alerts displayed to notify me of any malfunction. The failure occurred suddenly and without notice.I respectfully request that NHTSA open a formal investigation into premature transfer case failures on 2021–2023 Acura TLX Type S vehicles equipped with SH-AWD. This issue should be evaluated for recall eligibility or mandated corrective action to ensure driver safety. Thank you for reviewing this complaint.

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.

SUSPENSION, SERVICE BRAKES
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.
