The transfer case blew, whenever I accelerated fast when starting from slow speeds i would experience slippage with the wheels of my car as it was now a front wheel car instead of all wheel drive. I took it to Acura on September 14 and they did reproduce the problem, they changed the transmission and transfer case, and no there were no warning lights or check engine lights and the cars 4 wheel drive system on the dash told me all of my tires were working when they were not.

- The engine system failed and it is available for inspection -While driving on the highway at normal traffic speed, my vehicle suddenly developed a loud knocking noise and the check engine light lit up. Within moments, the engine lost power and became inoperable, leaving me unable to continue driving while being 300 miles away from home. This incident occurred at about 5-6AM, having to maneuver through traffic before the sunrise. This created a serious safety risk because surrounding vehicles were traveling at full speed increasing the risk of collision. There were no warning signs of this failure and I was unfortunately stranded on the highway in an unfamiliar town for hours with minors in the vehicle. -Yes, the vehicle was towed to a local dealeriship, Hahira Automotive Services, where the engine failure occurred and they confirmed that they were unable to start the car and the knocking sound was indicative of engine failure. I towed the car to an Acura dealership local to my home and they confirmed the same vehicle condition and that a takedown is required to fully inspect the engine. -The engine has not been inspected by anyone only the vehicle condition -There were no warning signs of engine failure prior to the incident

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 the federal safety agency 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.

While driving in humid, rainy conditions for over five hours, I experienced a sudden and dangerous loss of acceleration. Moisture appears to have built up, resulting in a misfire and a flashing MIL/Check Engine light. This occurred while I was overtaking another vehicle just before entering a restricted-width construction zone, making the situation extremely hazardous. The complete loss of acceleration lasted for about a minute. Afterward, I was only able to maintain minimal speed by flooring the accelerator. I continued in this limited-power mode until I could safely exit the highway. After shutting off the vehicle for 10 minutes, I restarted it, and it operated normally. After researching this issue, I found active recalls and service bulletins describing this exact behavior, including: the federal safety agency Recall Number: 25V‑031 Acura Campaign Number: EL1 Service Bulletin Number: 25-010 Additionally, an earlier bulletin describes identical symptoms: Service Bulletin Number: 20-053 (Version 4, dated March 12, 2024) Despite these matches, my VIN does not show any active recalls or bulletins. When I brought the car into the dealership to address this issue under the bulletin, they informed me they could not perform any service since my VIN was not listed. Given the severity of what occurred, I am requesting urgent assistance in updating or reviewing the recall eligibility for my vehicle. I would like to prevent this issue from recurring, especially in dangerous conditions. Thank you for your attention, and I look forward to your prompt response.
