Owners have filed 209 complaints
about the 2022 Acura MDX with NHTSA between 2021 and 2026.
The largest single group is the transmission & drivetrain.
Across this model's run it ranks 15 of 24 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 54
Against the median year of the Acura MDX. 50 means typical for this
model; 100 means roughly double.
Severity — 54
10.5% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 36
21% of failures with a mileage on record happened under
36,000 miles, against a national rate of
29%.
NHTSA files every complaint against a named sub-assembly, not just a
system. This is the difference between knowing it was "the engine" and
knowing which part of it — the list to hand a mechanic.

Recalls on the 2022 Acura MDX
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.
Canada — Transport Canada
Canada runs its own recall programme, and its campaigns do not
always mirror the American ones.
Recall 202625112,371 units in Canada
Seats And Restraints
Issue: On certain vehicles, the weight sensor for the front passenger seat may not have been manufactured properly. As a result, the passenger-front airbag and knee airbag could deploy in a crash that doesn't require them to. Note: This recall is an expansion of Transport Canada recall no. 2024-059. If the weight sensor fails, the SRS warning light would turn on in the instrument panel. Safety Risk: An airbag system that doesn't work properly could increase the risk of injury in a crash. Corrective Actions: The company will notify owners by mail and advise you to take your vehicle to a dealership to replace the passenger-front seat weight sensor.
Recall 202531815,574 units in Canada
Brakes
Issue: On certain vehicles, the brake pedal assembly may not have been manufactured properly. As a result, the brake pedal could move and cause you not to be able to apply the brakes properly, or to apply the brakes unexpectedly. This could also cause the brake lights to turn on without pressing the brake pedal. Safety Risk: Reduced braking and/or braking unexpectedly could increase the risk of a crash. Additionally, brake lights that turn on without the brake pedal being pressed could cause others not to recognize when the vehicle is braking or not braking and increase the risk of a crash. Corrective Actions: The company will notify owners by mail and advise you to take your vehicle to a dealership to inspect and, if necessary, replace the brake pedal assembly.
Recall 202502916,977 units in Canada
Fuel System
Issue: On certain vehicles, a software problem in the fuel injection electronic control unit could cause the engine to stall while driving. Safety Risk: A sudden loss of power to the wheels could increase the risk of a crash. Corrective Actions: Honda will notify owners by mail and advise you to take your vehicle to a dealership to update the fuel injection electronic control unit software.
Recall 202405966,846 units in Canada
Airbag
Issue: On certain vehicles, the weight sensor for the front passenger seat may not have been manufactured properly. As a result, the passenger-front airbag and knee airbag could deploy in a crash that doesn't require them to. Note: If the weight sensor fails, the SRS warning light would turn on in the instrument panel. Safety Risk: An airbag system that doesn't work properly could increase the risk of injury in a crash. Corrective Actions: Honda will notify owners by mail and advise you to take your vehicle to a dealership for an inspection if the SRS warning light is on. If the SRS warning light is on due to a faulty weight sensor, the weight sensor will be replaced. When repair parts are available, Honda will send you a second letter.

VEHICLE SPEED CONTROL
On April 17 2026 while driving my 2022 Acura MDX at very low speed in a parking lot, the vehicle suddenly accelerated forward without warning and surged into bushes before I could stop it. I did not mistake the gas for the brake pedal. This felt like a sudden unintended acceleration event. I was preparing to park in a stall and the vehicle lunged forward unexpectedly. I applied the brake, but the braking did not immediately stop the forward surge. Earlier, I experienced another unusual event in which the vehicle abruptly auto-braked, jerked, and made a warning sound while I was slowing for a red light. I noticed the car felt as if it was surging a bit on residential streets and was about to mention it during the next service. This incident has caused me to lose confidence in the safety of the vehicle. I contacted Niello Acura who has been very cooperative. I was told the issue would need to be duplicated or that they could only inspect it if a code had been stored once the car is repaired. The car is currently being repaired with close to 7,000 in front end damage. I am reporting this because a sudden unintended acceleration presents a serious safety risk and could easily have caused a more severe crash or injury. I did research on this issue and have found various reports of unintended accelerations in the Acura MDX forums from various years but was unable to find any recalls or outcomes with these reports My concern is this will be dismissed as "operator error" or a phantom incident that cannot be reproduced.

STEERING
While driving at approximately 35 mph on a surface street with my wife and five-year-old son in the vehicle, the electric power steering system failed and steering assist was reduced. The instrument panel simultaneously displayed and cycled through multiple warnings including "Electric Power Steering System Problem — Steering Assist Reduced," "Brake System — Brake Hold System Problem," Vehicle Stability Assist, and Hill Start Assist. There were no warning lamps, messages, or symptoms of any kind prior to this failure; the first indication was the failure itself while the vehicle was in motion. On the two engine starts following the incident, the same dashboard warnings reappeared, although power steering and vehicle operation seemed normal. On the two starts after that, the vehicle started with no warnings and no indication of any problem. So the steering effort increased during the initial failure and I was unable to rely on power assist while moving in traffic, which created a risk of loss of directional control and a crash for my occupants and other road users. On Aug 11,2026, the vehicle was taken to an authorized Acura dealer, which confirmed a stored diagnostic trouble code and diagnosed a failure of the VSA (Vehicle Stability Assist) modulator-control unit, recommending replacement. The vehicle has not been inspected by the manufacturer, police, or an insurance representative. No repairs have been performed to date and the vehicle and component remain available for inspection upon request. Mileage at the time of failure was 40,090. I have video of the instrument panel recorded during the event and it is available upon request. I have reviewed complaints filed with NHTSA describing what appears to be the same simultaneous multi-system failure on 2022 and 2023 Acura MDX vehicles.

Vehicle exhibited a fluid leak at the rear of the engine near the transmission/transfer case junction. An independent shop is currently evaluating; suspected power take-off unit failure. This matches the failure pattern described in NHTSA Defect Petition DP26001 covering 2022-2023 Acura MDX and 2021-2023 Acura TLX for interfacing spline failure between the transmission and the rear-wheel-drive power take-off unit. Separately, while pulling out into traffic, the vehicle hesitated and failed to accelerate as commanded, chugging briefly before delivering power. This nearly resulted in a collision. No warning lamps or messages appeared at any time. Whether this drivability event and the fluid leak share a cause is UNKNOWN, but I am reporting both given the open defect petition on this component. Vehicle at approximately 75,000 miles, outside powertrain warranty by roughly 5,000 miles. Manufacturer declined assistance when contacted. Component is available for inspection upon request. Sudden loss of all-wheel drive without warning is a safety concern in Michigan winter driving conditions Repair has been quoted at approximately $3,600 for the transfer unit alone, plus labor, with no manufacturer assistance offered.

The splines to the transmission and front transfer case are worn and stripped and that is causing a bad transmission fluid leak.

Acura is not cooperating and the cost to repair is $14,000. I noticed a transmission fluid leak, so I took the vehicle into the Acura dealership.

Began to notice a knocking noise from lower engine compartment in late May 2026. No warning lamps, messages, or other symptoms. Dealer (Zimbrick Acura, Middleton WI) confirmed on 06/30/26 that noise was coming from transmission assembly. Dealer identified that the transmission was leaking fluid from the output shaft seal, and upon disassembly identified that the interfacing splines between the transmission and the rear wheel drive power take off unit (PTU) were failing. Dealer ultimately replaced transmission and PTU. This is the same issue as described in a previous petition (no. 11712885) but was identified prior to complete loss of all-wheel drive.

The car made a clunk sound while driving and wouldn't accelerate. After coming to a stop and trying to take off, the car still had difficulty accelerating. After turning the car off and back on everything appeared fine. The loss of acceleration was unexpected and there were no warning lights or indication of an issue. The lack of ability to accelerate along with the clunk sound caused unnecessary safety risks by not allowing the car to maneuver out of danger and disrupting the flow of traffic unexpectedly. The car then began leaking oil. The Acura dealership noted that the oil was transmission and power transfer unit oil and the car no longer has all wheel drive but only front wheel drive. The loss of all wheel drive without any indication or warning is a serious safety issue because it affects all aspects of drivability (handling, acceleration, traction). They said over time the splines of the power transfer unit input shaft rust and then sheer off which causes metal to damage the transmission seal and power transfer unit seal. The service manager said this was a known issue due to bad engineering and there is no way to prevent it. The vehicle is unchanged since the incident and can be inspected.

The malfunction was both rear drains from the sunroof were clogged and possibly kinked. The dealership might still have the components but did not give us access to them. The clog caused the water to enter the vehicle and accumulate. In addition to wet carpeting, an electrical component shorted and failed damaging the Infotainment system. If this had happened during vehicle operation with water moving around, electrical systems could suddenly fail while driving. The vehicle was inspected by the insurance adjustor but was deemed a maintenance issue even though there exist no maintenance instructions or dealership directives for maintenance or inspections. Owner maintenance would not be possible as special tools would be needed without which damage to the drain lines might occur. There was no warning, messaging, or instructions that maintenance was necessary for this item or that it could fail. The first sign was the sound of sloshing water in the vehicle during driving and the failure of the infotainment system. As a remedy, the dealership insisted on replacing the drain lines rather than cleaning them out, which implies that either the dealership was creating extra work for themselves or the drain line could not easily be cleaned.

My 2022 Acura AWD MDX with 95795 miles lost the power to the rear wheels. The spline between the transmission and the transfer case stripped. The transmission and transfer case had to be replaced for $14,442.37. I had Assurant for extended warranty, and they reluctantly paid most of the repair.
