I am submitting this complaint regarding my 2022 Acura MDX Advance, currently with 71,007 miles. After completing the standard transmission fluid service around the 60,000-mile maintenance interval, I began noticing abnormal drivetrain/transmission behavior that was not present before. At times, the vehicle feels as if the transmission is slipping, hesitating, or failing to transfer power smoothly. Acceleration can feel delayed, uneven, or weaker than normal, and on some occasions the vehicle seems to surge or accelerate slightly in a way that does not feel consistent with normal pedal input. This is a safety concern because the vehicle may not respond predictably when accelerating from a stop, merging, passing, or driving at highway speeds. A delay, slip, surge, or loss of expected acceleration could increase the risk of a crash, especially in traffic. The symptoms appear to involve the transmission, drivetrain, torque converter, transfer case, software calibration, or related components, but I am requesting a proper investigation to determine the actual cause. My concern is that this issue could worsen or affect other 2022 Acura MDX vehicles if it reflects a broader defect. I am requesting that the federal safety agency document this complaint and review whether 2022 Acura MDX models may have a safety-related issue that can cause slipping, hesitation, surging, delayed acceleration, or loss of expected power after normal maintenance. Acura should evaluate whether owners need inspection, repair, software updates, or other corrective action.

What owners say
I own a 2022 Acura MDX SH-AWD with approximately 85,000 miles. The issue began suddenly while driving around 5 mph when two loud bangs were heard from the rear drivetrain/transfer case area. After the initial incident, the vehicle was driven home, and the problem became consistently noticeable during any acceleration from a stop or low speed. The drivetrain would clunk/slip during acceleration and exhibited abnormal engagement behavior. Due to concern about causing further drivetrain damage or a potential safety issue, the vehicle was subsequently towed to an Acura dealer for diagnosis. The Acura dealer confirmed that both the transfer case and transmission require replacement due to “worn teeth on splines.” The repair estimate specifically states: “REPLACE TRANSFER CASE AND TRANSMISSION DUE TO WORN TEETH ON SPLINES.” Estimated repair cost is approximately $11,400. I have photographs and repair documentation related to the failure. This failure created a potential safety concern because the drivetrain was no longer operating normally and produced loud clunking/slipping during acceleration from stops and low speeds. A drivetrain or power transfer failure could increase the risk of loss of propulsion or inability to accelerate normally into traffic. The issue was reproduced and confirmed by the Acura dealer. The vehicle has been regularly maintained, including drivetrain fluid services, through Acura/Honda service facilities. There were no warning lights, dashboard messages, or electronic indications before or after the failure event. The only indication was the loud banging noise from the drivetrain/transfer case area and the resulting abnormal drivetrain behavior during acceleration. The service manager also indicated they had seen several similar cases involving this issue.
While driving in snow and in light rain noticed the MDX pulling and slipping. I realized that only the front tires were trying to drive the vehicle which was causing the car to pull sideways and slip all over the road. I made an appointment with the ACURA dealership and they found the transmission splines stripped out that drive the rear wheels. There was no warning lamps or indication that anything was broke other than very hard to drive in any kind of snow or rain. Talking with the dealer and looking online this seems to be happening to other MDX s also. My car was fixed under the manufacturer warranty and the transmission and transfer case were replaced.
At only 44,318 miles, my 2019 Acura MDX began showing clear transmission problems in the lower gears — including delayed acceleration, gear slipping, and jerky movement when starting or turning at low speed. These symptoms posed an immediate safety risk, especially when merging into traffic or making turns across oncoming vehicles. I first brought the car to Oakland Acura, which incorrectly diagnosed it as a transfer case issue. Their misdiagnosis delayed the repair process and added unnecessary cost and time. I then had the vehicle evaluated at Acura Concord, where it was correctly diagnosed as transmission failure in the lower gears. An independent, certified mechanic also confirmed the same diagnosis. Despite multiple confirmations of premature transmission failure — and a full maintenance history — American Honda offered only a $900 discount on a $9,600 repair, citing the vehicle being just outside the time warranty (but with low mileage well under 50K). I believe this is a manufacturer defect, not a wear-and-tear issue. Safety Concern: This transmission failure is not just inconvenient — it is dangerous. The vehicle hesitates when accelerating from stops or low speeds, which can lead to accidents at intersections, highway merges, or left turns. The misdiagnosis further delayed identifying and addressing this issue. I am filing this complaint to urge the federal safety agency to investigate whether this is part of a broader pattern with Acura MDX transmissions, and to help prevent similar risks for other drivers and families.
SO my car had a torque converter recall at some point i was not notified of it to get it fixed. as such i drove it across the us and ended up making the transmission slip so bad that it would not go into gear anymore. since this i have taken it a dealership where the recall was performed after the fat and now they want me to buy a new transmission.
The contact owns a 2020 Acura MDX. The contact stated while coming to a stop, the contact noticed that the vehicle inadvertently slipped into neutral. There was no warning light illuminated. The contact restarted the vehicle several times to shift back into drive. The contact also noticed that the steering wheel had seized, making the steering wheel difficult to turn. The vehicle was taken to the dealer but was not diagnosed or repaired. The manufacturer was not mad aware of the failure. The approximate failure mileage was 26,000.
Transmission slips and make chirp sound, and failed completely during driving at 86000
The front bumper of the car is becoming unattached. There is a space underneath the headlights. The panel gap between the fender and front bumper has grown at the top, indicating the bumper is slipping from the top down. The problem appears to be getting worse. The plastic underneath the bumper is now becoming detached. I fear some of the clamps behind the bumper have failed. I also fear this may begin impacting critical systems and sensors behind the bumper. The Acura dealer denies any issue exists.

Transmission issues with my 2016 Acura MDX slipping into neutral and staying there while driving at high speeds on interstates. This could've caused injury to myself, my passengers, and other drivers on the road due to the high speeds. Without being to able to accelerate when needed, it could've resulted in harm. Transmission Service Problem and Blind Spot Malfunction lights appeared. I took the vehicle to Acura for service 3 weeks before the last incident and Acura said there was no problem and to bring it back if it happened again. 3 weeks later, it happened again. I had reported slippages in the transmission for several service checks with no issues found by Acura. After the most recent incident, Acura recommended to either keep driving and bring it back or replace the transmission. Diagnostics were run and error codes cleared. The CSR at Acura mentioned he saw this on at least 5 Acura 2016 MDXs this year already. The warning lights did not appear until the last issue. Several other incidents occurred with no warnings. All transmission maintenance activities have been performed.
