The transmission and transaxle malfunctioned. Evidence was a leak from the transaxle. The dealer confirmed that the vehicle was operating in 2WD mode even though it did not detect any issues from its onboard sensors, and the car thought it was still sending power to all 4 wheels. There were no warning lights that the vehicle was no longer driving in 4wd mode, so the driving dynamics would've been unexpected in conditions that 4wd would normally help, like rain and snow. Unexpectedly experienced tire spin in the rain, for example. The dealer confirmed that both the transmission and transaxle need to be replaced, under the powertrain warranty. The spline between the transaxle and transmission were worn, causing the transaxle to not spin the rear wheels.

The transfer case spline stripped preventing power to be sent to the rear wheels
Upon normal highway driving a couple of months ago, began to notice shifting that was not smooth and rpm "surges" on hills despite constant throttle. Upon taking car to dealer, inspection revealed an internal spline failure between transmission and transfer case. Lead mechanic explained it was not the first he had seen of this model and that it was clearly internal and caused by a manufacturing and/or assembly defect. I caught the problem early enough to not have a complete car failure; however, left untreated, it would lead to a transmission failure. The remedy was a full transmission and transfer case replacement, with repair costs exceeding $13,000. Given car had 84,000 miles, it was not covered by 70,000 Power Train Warranty from Acura. Pictures of parts below.
Many attempts in the last 5k miles made to diagnose unsafe uncomfortable front vibrations. Vehicle erratically shaking above 50mph. Returned vehicle to CarMax (where vehicle purchased), and 3 separate individual Acura dealers made attempts. Rotated and rebalanced tires several times with a scan tool connected as a technician drove vehicle with no results Finally Acura dealer an hour away from my home diagnosed faulty front transfer case pending anything further. Conveyed the shaft splines into transfer case and other end to transmission may be faulty, rounded out, and will report findings. After inspected, transmission output splines for shaft going to front transfer case have been found rounded out as well. Dealer reported this again under warranty and ordering transmission. Coming up on 30 days front transfer case, transmission, and possibility of further repairs. Compiling written documentation. Vehicle repair attempts at Carmax Newport News, VA, Southern Acura Newport News, VA, Hall Acura Virginia Beach, VA, and Crown Acura Richmond, VA.
driving on highway car suddenly lost power check engine light came on. was able to coast off to an exit on the highway. car eventually unable to move. the car was towed to the dealer. the transmission and power take off unit was replaced.
My transfer case went out at an unknown mileage with no indication on my dash that there was a failure. It converted the vehicle to front wheel drive while indicating it was still having the back wheel spinning on the all-wheel drive indicator on the dash. During a recent snowstorm, there were multiple instances when I pulled out from an intersection thinking I had good traction I'm pulled out and then my wheels started spinning almost causing an accident. I thought that was weird so I brought it to my local Acura dealer and explained what happened and they tested it and found that the transfer case splines were bad along with the splines that attached to the transmission. They replaced both the transmission and transfer case under warranty. No police or insurance representatives were involved as there were no accidents.
Front driver wheel has started to spin when power applied from a stop or from a slow roll. Tires are in great condition, further research indicates that this is a typical issue between the transfer case and differential. Splines get stripped and the car essentially becomes 2 wheel drive.

The All Wheel Drive of my 2022 MDX has been going out in the rear, and only the front wheels are powered. This happens nearly every time I drive the vehicle for the last 2 months, at least. My safety is at risk because I live in Montana and the roads have been getting icy with current weather conditions. When the AWD drive gives out, I lose all power briefly as the front tried to regain power. Going up mountains with this issue is very dangerous. It also goes out in "snow" mode. I have sent the Acura warranty department numerous photos, via email, of the error message as well as videos of the message popping up. I also started a log of the error as of 11/09/23. I live over 400 miles from the closest Acura dealership. I asked if the local Honda dealership can look at it and after over a week of waiting to hear back, was told I needed to take it to Acura. I refuse to drive it over 400 miles in winter conditions. I asked for it to be towed to Acura last Monday, 11/20/23, and have yet to hear back. The warning message reads, "All Wheel Drive system problem. Only front wheels may be powered, see your dealer." Additional, snall rocks from snow protection keep getting stuck between the break rotors and the back plate. It causes a loud screeching sound until the rocks are dislodged. The rear brakes now sweak.
I am writing to report a significant issue concerning a leak in the transfer case of my 2022 Acura MDX Type S, VIN: [XXX] . This malfunction poses a potential safety risk to myself and other road users. 1.Component Malfunction: •The malfunction occurred in the transfer case of the vehicle. Yes, the transfer case is available for inspection upon request. 2.Safety Risks: •The leak could potentially lead to inadequate lubrication within the drivetrain, causing it to malfunction while driving, which might result in loss of control or an accident. 3.Problem Confirmation: •The problem has been confirmed by an authorized Acura dealer, who identified the leak and proposed either a seal replacement or a complete transfer case replacement as potential solutions. 4.Inspections: •The vehicle has been inspected by the dealer and is scheduled for a follow-up inspection to ascertain whether the seal replacement resolves the issue. As of now, no inspections have been conducted by the manufacturer, police, or insurance representatives. 5.Warning Signs: •There were no warning lamps or messages indicating a problem. However, I was advised of the leak when the car was on the lift for a tire change, which prompted a further investigation. This issue raises concerns about the potential safety risks not only to myself but to other drivers on the road. I am worried that others with the same vehicle model might experience similar problems, which could lead to dangerous situations if not addressed promptly.

Vehicle experienced reduced power and many alarm messages came up. I pulled to the side of the road to get out of traffic. I turned off the engine and attempted to restart, the engine would run for 5 seconds and then shutdown. I learned later that the turbo outlet hose had become detached from the hose fitting. It was under the motor and only accessible when the vehicle was on a hoist. The real reason for my complaint is that with the engine unable to stay running, the transmission could not be shifted to neutral and there is no shift lock feature to manually put the transmission in neutral either. So, if I had been stuck in traffic when the engine lost power, there would have been no way to push or tow the vehicle to a safe place. This seems like a function that would be important to have on a vehicle.
