Defect investigations
All wheel drive allegation
The Office of Defects Investigation (ODI) has completed its review of a Petition dated January 9, 2026, requesting an investigation into the loss of the optional all-wheel drive capability in model year (MY) 2021-2023 Acura TLX and MY 2022-2023 Acura MDX vehicles. The Petition alleges failures in the interfacing splines between the front wheel drive transaxle and the rear wheel drive power take off unit. Failure of these splines prevents the transfer of drive power to the rear axle, making the vehicle front wheel drive only. The Petition further alleges that this failure reduces vehicle directional control. Most traditional AWD systems utilize mechanical and passive measures. These systems have the tendency to distribute torque along the path of least resistance, such as a wheel that has lost contact with the ground or is on a low friction surface such as ice. To compensate for this, many manufacturers use the brake system to redirect torque to the wheels with more traction. However, in this style of AWD system, a failed drive shaft or similar disconnection prior to the brakes often results in drive power being lost to the disconnected component. The consequence of this loss is the inability to maintain speed with surrounding traffic which increases the risks of collisions and injuries to the vehicle occupants. The Subject Vehicles are built upon a platform that was designed primarily as Front Wheel Drive (FWD). The SH-AWD system functions more as a performance enhancement feature rather than a stability feature. Even if the SH-AWD is nonoperational, the vehicles retain full mobility via FWD. In addition, the Vehicle Stability Assist (VSA) remains functional, ensuring directional stability through traditional engine and brake-based traction control. Although the condition raised by the Petitioner may degrade the vehicleâs performance characteristics, there is insufficient information to indicate a potential unreasonable safety risk. ODI reviewed 62 Vehicle Owner Questionnaires (VOQs) and several EWR Field Reports alleging the loss of SH-AWD and its impact on the driving dynamics of the subject vehicles. During its analysis, ODI determined that the failure is localized to the mechanical interface between the FWD transaxle and the PTU. Specifically, the failure is the shearing or stripping of the interfacing splined shafts between the FWD transaxle and the PTU, resulting in a permanent loss of torque transfer to the rear of the vehicle. Upon reviewing the technical details of SH-AWD, ODI has found that this failure does not result in any loss of motive power or lead to a loss of vehicle control. Several complaints indicated that the operators were unaware of the mechanical fault until encountering a low friction surface or the condition was identified by a technician during routine maintenance. The SH-AWD system lacks any form of direct feedback for monitoring real time torque transfer to the rear wheels. Therefore, the system will continue to display information indicating power is being supplied to the rear wheels even when power is actually only supplied to the front wheels. ODIâs review did not identify sufficient evidence to indicate that the misinformation has presented a safety issue in the field. ODI did not identify any reports of loss of motive power or vehicle control that could be attributed to the loss of SH-AWD. ODI is not aware of any crashes involving the Subject Vehicles that resulted from the loss of SH-AWD. After thoroughly assessing the material submitted by the Petitioner, consumer complaint information in the federal safety agencyâs databases, and other relevant information already in possession of the Agency, the federal safety agency has not found sufficient evidence to indicate that the loss of AWD as alleged by the Petitioner is likely to present a safety related defect that would warrant a formal investigation. After full consideration of the available information, and in view of the federal safety agencyâs enforcement priorities, the Petition is denied. A denial report will be posted in the Federal Register. The closing of the petition does not constitute a finding by the federal safety agency that a safety related defect does not exist, and the agency reserves the right to take additional action if warranted by future circumstances. The Petition can be viewed at under ODI Number 11712885.

What 2022 Acura MDX Type S owners say
Most recent owner complaints, unedited.
Reporting an additional case in support of ongoing defect petition investigation DP26001. 2022 Acura MDX Type S SH-AWD, currently at 63,700 miles. While driving and making a turn, I heard a grinding noise with no warning lights illuminated. I stopped immediately and shut off the engine but noticed no abnormality. I restarted the vehicle and drove with no further issues or noises. Later, during a scheduled oil change, I discovered that the area between the transmission and PTU was covered in oil. The Acura dealership diagnosed a bad PTU seal and replaced the PTU under powertrain warranty, but completely disregarded my concern regarding investigation DP26001 and the known issue with stripped splines. The leak was repaired, but several weeks later while driving in the rain, the vehicle felt very unstable during acceleration on wet pavement. I raised the vehicle on a lift and engaged drive to inspect AWD function. The rear wheels were not spinning while the front wheels were, and the driveshaft was also stationary. When I brought this to the dealership’s attention, they stated this is normal SH-AWD behavior — however, I have personally observed all four wheels spinning under identical conditions in another Acura of the same model and configuration. I am confident the transmission-to-PTU splines are stripped and am escalating this to Acura corporate for further investigation.
Under medium acceleration vehicle shuddered a lot. Currently it’s only driven by the front wheels and it will torque steer a lot. I’m assuming my splines are stripped to transfer case. Thankfully, I am under warranty and I’m going to get this repaired.
When about to make a left turn since oncoming traffic on to highway I hit the gas quickly after stopping and heard a loud bang. Drove till I got off the highway at a red light I hit the gas and noticed the front wheels was spinning and realized it wasn't a awd. Took it the dealer and they realzied the driveshaft was spinning by hand.
The component that malfunctioned was the transfer case, the vehicle was already repaired so an inspection isn't possible anymore. The vehicle behaved as normal until the accelerator was pressed enough to make the front wheels lose traction, in which the vehicle couldn't send power to the rear, because the transfer case was shredded up. When needing to accelerate quickly in traffic, the vehicle would completely spin up the front tires, not being able to put the power down. The dealer reproduced the problem, but initially stated that it was most likely due to the salt on the road (it was winter). As spring arrived, the problem still persisted, in which the dealer checked the transfer case and found it was shredded. They replaced the transmission and transfer case under warranty. There were no warning lights, but accelerating quickly would cause the car to spin up the front tires uncontrollably. In corners, this meant severe understeer that could be dangerous in the wrong circumstances.
Catastrophic Power Take-Off Unit (PTU) and Transmission spline failure on a 2022 Acura MDX Type-S vehicle. Had dangerous loss of traction and unexpected handling characteristics with rough shifting, RPM Surges, Sensor problem LOSS OF Power, Delayed shifting with Jerky ride, and a smell of burning oil or rubber, also would move into reverse and the Drive Letter "D" was blinking. The problem was confirmed by Independent service center and it was inspected by the manufacturer. Messages indicating engine/transmission issues appeared on Jan 4, 2026; *Transmission system problem. Paddle shifters not available. See your dealer. *Emissions system problem. Power may be reduced. See your dealer. * Transmission system problem. Avoid heavy acceleration and High speed. See your dealer. * AWD All Wheel Drive system problem. Only the Front wheels may be powered. See your dealer. Notes: (A.) Transmission system errors and infotainment warnings appeared upon concluding a round-trip 3,000+ miles from Southern California to East Texas and back home to Yuma AZ. (B.) After Honda Motor Co gave a 75% Goodwill Offer to replace control box and valves, they indicated that the transmission also need to be replaced. Furthermore, they rescinded the 75% Goodwill coverage which appears to be based solely on the incorrect assumption that third-party transmission repairs were performed and that the transmission was overfilled.
I own a 2022 MDX Type-S. I recently read about complaints about TLX and MDX models losing their AWD system and only resulting to FWD. I was a victim of this in Montana and it was a long fight with Acura / Honda to look at the problem. It was also very dangerous as I worked up in Big Sky and would rely on the AWD system in snowy conditions. This system would always fail. After a long fight, they finally towed my vehicle back to Salt Lake City, where it was purchased from, and replaced a "sensor."
Starting hearing issues late 24 of MDX and TLX losing all-wheel-drive due to splines stripping between the transmission and transfer case. Had car thoroughly inspected and fluid samples taken in December of 24. In February on 25 with a frame rattling bang as I was pulling out onto a street, rear wheel drive went out at 64k. No warning lights and no indicators, dash showed all 4 tires pulling. Dealership verified system was stripped as rear tires were not turning. Also discovered connection between the two units failed allowing water to get in and wash all grease out around the spines. New transmission is two parts number newer than original and transfer case is one parts number newer than original. Also noted transmission and transfer case take less fluids than original. Car feels a lot tighter and smoother on shifting with new units.
The vehicle is experiencing a catastrophic mechanical failure of the transfer case/transmission splines, resulting in a 'Loss of Motive Power.' On two occasions while merging into high-speed highway traffic, the engine revved to high RPMs, but the vehicle failed to accelerate for approximately 5 seconds (Mechanical Neutral Drop). These incidents resulted in near-collisions. The vehicle also exhibits violent torque steer and unpredictable handling. The issue was initially reported to an authorized dealer at 70,320 miles but was misdiagnosed as 'no codes were present.' Subsequent inspection by a second dealer confirmed a mechanical failure of the drive splines. This is a purely mechanical failure that does not trigger dashboard warning lights or Diagnostic Trouble Codes (DTCs), leaving the driver unaware of the impending drivetrain failure until power is lost. First signs of a problem: Late August 2025 First loss of motive power incident: Early October 2025 Second loss of motive power incident: [XXX] Initial Dealer Report: October 28, 2025 (MetroWest Acura) Confirmation video from Acura of Boston: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Vehicle is 3 years old with 60K miles. Transfer case became defective under normal driving and with regular recommended maintenance. We did not know this occurred until a recent dealership visit for another issue. We do not know how long this has been an issue. When the transfer case malfunctioned, there were no warning lights and vehicle has been only functioning in front-wheel drive (designed to be AWD) which is extremely dangerous during the midwestern winters as the weight of the rear of the vehicle leads to sway. Issue was detected by the dealership who states the fix is to replace the entire transmission and transfer case.
