general problems of the 2022 Acura MDX - part 2

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.

My vehicle has 80,000 miles. It has a popping sound when accelerating from stop. Dealership found metal chunks in the transmission and transfer case. Luckily I brought the problem to them before catastrophic failure while driving. Both are needing complete replacements.

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.

While driving a 2022 Acura Mdx advance awd in snowy conditions, I noticed reduced traction and abnormal drivability. Dealer inspection confirmed a catastrophic failure: the front differential and transmission splines were stripped, causing the vehicle to operate in front-wheel drive only. The dealer verified the failure and documented it as a defect on the repair order. The vehicle was maintained exclusively at the dealership since new, and failure occurred at approximately 76,000 miles, outside the original powertrain warranty. There were no warning lights prior to the failure, but loss of awd in snowy conditions created a significant safety risk. This is a safety-relevant defect affecting traction and stability in adverse conditions.

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.

During a winter freeze event, the vehicle was unable to climb a slight incline despite being equipped with all-wheel drive. The rear wheels did not appear to be receiving power, and the vehicle experienced significant wheel slip under light throttle input. This occurred in normal driving conditions and was unexpected given the vehicle’s awd system. There were no warning lights, diagnostic messages, or fault indicators displayed on the instrument cluster at the time of the incident. The lack of any driver notification made it difficult to identify that the awd system was not functioning properly. After experiencing the issue, the vehicle was taken to an authorized dealership for inspection. The initial assessment did not identify a problem. However, after further review and comparison with a properly functioning vehicle, the dealership confirmed a failure within the sh-awd system. The affected components were replaced under warranty. The failed components should be available for inspection upon request. The safety concern stems from the absence of warning indicators combined with the loss of intended awd functionality. In low-traction conditions, the inability of the system to properly distribute power can increase the risk of loss of control, reduced acceleration capability, or inability to safely merge or climb inclines. No prior warning lamps or alerts were presented before the incident.

There were two major failures in my vehicle within a couple of weeks. The first was a lower ball joint failure. The passenger side lower control arm was replaced. The second major failure was the transfer case seal on the transmission failed and the transmission is being replaced. The vehicle has been serviced since its new purchase at Acura dealerships.

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.

Transmission issue… grinding and not accelerating…. When it is at a stop and moving again . . Turning with accelerating. . It moves really slow.

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. ".

The vehicle makes noise while shifting from park to reverse to drive. Transmission fluid and oil fluid leaking while I had driven only 450 miles. Had reported the issue to the service department. They informed that since the engine is new it will take a while for the transmission gear to quiet it down. They can't find any leakage for the first two times when I brought the vehicle for them to inspect. Their service manager was able to identify the issue and assigned the technician to trace it down. My car is currently in their shop for the third time since I just purchased it on August 19th, 2021.

After 4 times of taking the vehicle to two dealerships for the same concerns, I am having the following problems with my vehicle at this time:: wind/whistling/whining noise heard while driving and has gone unresolved. The car consistently makes a whining/whistling noise when reaching speeds between 40-65mph and has been a known issue with this year make and model per documentation provided to me by the dealership.

A transmission error popped up on the car and the vehicle would not accelerate past a few miles per hour. The issue is happening intermittently and the dealer and Acura service claims it’s a random issue. A sign that says brake fault keeps popping up as well and it’s really scary to drive the car. Acura service said it’s normal and working as designed and there is no fix at the moment.

I purchased the new Mdx 2022 on may 27th 2021. On may 31st, while driving on the interstate 287 at 65mph, the car suddenly stop accelerating. When I pushed the gas pedal, the engine only revved up but the car continued to slow down. I pulled the car on the shoulder lane, shut the engine off and restarted. The problem continued. The dashboard had the warning sign "transmission system problem. Avoid heavy acceleration and high speed. See your dealer". It also showed the sign "emission system problem, power may be reduced. See your dealer". The problem occured on the busy interstate 287 in central jersey without any prior warning, on a brand new Mdx 2022. We were lucky since it was 11pm and we were in right lane, so could pull over the shoulder. In the online forums, I have found one more user with the similar problem. The Acura dealer has inspected the car and requested the transmission system change. The car has 1071 miles only and 4 days out of the dealer's parking lot.

Transmission failed right as I drove off the lot. The car initially started to jerk and then was revving to 7000rpms and would not speed up past 25mph. The car also stopped moving when I put it in reverse. When I tool it back to the lot within the hour, around 3 days later they told me the transmission failed ln the car. This was a brand new car and should not have happened.
