Auto start/stop system - yes, it is available for inspection. The vehicle turned off at a buy intersection and it was a couple of minutes before it would restart. The vehicle will be inspected my a dealer on Monday. No manufacturer, police, insurance representative has inspected the vehicle. There was a message when the vehicle turned off but I can't recall what it said as other drivers were blowing horns and I was focused on my safety at the time.

My vehicle stopped handling as it usually had and I at a significant decrease in traction and slid off the road and slammed into a road sign. No injuries but significant damage to the vehicle. It seemed as though the all-wheel drive was not working. No warning lamps and computer system indicated that all four wheels were getting power. Took it to dealer and they confirmed that the all-wheel drive system has failed. Splines in the transfer case stripped and transmission needs to be replaced

The contact owns a 2025 Acura MDX. The contact stated that while driving approximately 30 MPH, the vehicle bucked for approximately 3-seconds before the vehicle stalled. The hazards were activated, the vehicle was turned off, and the contact waited before restarting the vehicle. While restarting the vehicle, several warning lights quickly flashed, and the vehicle failed to exceed 4 MPH while driving to the nearest parking lot. The vehicle was towed to the dealer, but was not diagnosed. The vehicle was not repaired. The contact became aware of NHTSA Campaign Number: 25V031000 (Fuel System, Gasoline, Electrical System); however, the VIN was not included. The manufacturer was not made aware of the failure. The failure mileage was approximately 24,000. The VIN was not available.

SUSPENSION, UNKNOWN OR OTHER, ELECTRICAL SYSTEM
I am filing a complaint regarding my 2022 Acura MDX Type S with approximately 70,700 miles. The vehicle developed a suspension system warning, and upon inspection by an Acura dealership, I was informed that the suspension stroke sensor and floor wiring harness are corroded and require replacement. I was quoted approximately $12,000 for the repair. This failure is extremely concerning because the vehicle is only a few years old and this type of corrosion affecting a major wiring harness should not occur under normal operating conditions. The affected components are part of the suspension system, which directly impacts vehicle handling and safety. Due to the failure, the suspension system may not function properly, potentially affecting ride height, stability, and overall control of the vehicle. This raises safety concerns, especially at highway speeds or during emergency maneuvers. There was no prior warning of water intrusion or external damage that would reasonably explain this level of corrosion. This appears to be a premature failure of a critical electrical component. Acura has only offered minimal goodwill assistance, leaving the majority of this extremely costly repair as the responsibility of the owner. I am concerned that this may be a broader issue affecting other vehicles and that it could pose a safety risk if not addressed. I am requesting that this issue be investigated. Thank you.

SUSPENSION
A little over one year after purchase, I began receiving dashboard warnings related to the air suspension and braking systems. I scheduled service with the selling dealer (located over two hours from my home). By the time of my appointment, the rear of the vehicle was visibly unstable and bouncing during operation. Upon arrival at the dealership, while the technician was driving the vehicle into the service bay, the rear air suspension bag exploded. Once the vehicle was raised on the lift, the opposite rear suspension bag also exploded. I was informed by dealership personnel that had this occurred while I was driving – regardless of speed – it could likely have resulted in a crash. The stated cause of failure was severely corroded rear stroke sensors. Including that incident, I have had a total of 5 corroded stroke sensors replaced within an approximately one-year time frame. This appears to be a recurring and systemic defect rather than isolated component failure. The repeated corrosion of critical suspension components in a nearly new vehicle raises serious concerns about moisture intrusion, improper sealing, or design defect affecting safety-critical systems. This issue creates a significant risk of sudden suspension failure, loss of vehicle control, and potential crash. I am concerned that other owners may experience similar dangerous failures without warning.The vehicle has been serviced only at an authorized Acura dealership, and all repairs are documented. Exact dates of each repair: 4/10/25 – Both rear stroke sensors (mileage: 13,632), 9/24/25 – Left rear, 2/6/26 – Right front, 3/20/26 – Left rear, Current mileage: 25,160

SUSPENSION, UNKNOWN OR OTHER
MDX Type S with 63k miles. After performing diagnostic check there were several fault codes related to the vehicle's suspension system. Upon inspection, they identified issues with the ride height (stroke) sensors and wiring. The right rear, left rear, and right front sensors are affected. The right rear sensor has a broken pin, and part of that pin is stuck in the wiring connector. The left rear sensor also has a pin that is corroded. Additionally, the main wiring harness along the floor is corroded. This is due to poor location of wire harness in the Type S, and corrosion was due to salt exposure from icy roads. Dealership confirmed this was a known issue and had about a dozen of these replacements in the last few months.

POWER TRAIN
In January of 2026, when driving under normal conditions, the 2022 Acura MDX made a loud clunking noise and power was temporarily disrupted. The vehicle had to be stopped on the side of the road as the clunking noise persisted. This occurred on a major highway and put the driver and passengers at risk as we had to quickly get to the shoulder. After inspecting the vehicle for any visible signs of damage we continued home without issues. Now, March of 2026, we took the car for routine service and was contacted by the dealership and informed the transfer case and transmission needed to be replaced. The dealership indicating they were in contact with Honda USA to see what they could do for us. A quick search of the Internet revealed NHTSA DP26001, so we now know this issue has occurred on many Acura MDX's of the same year. No warning lamps illuminated. We were unaware that the vehicle was running in 2erWD instead of 4WD. There were no warnings leading up to the event.

Please add me to the compliant pool. My transfer case/transmission went out - 2022, 80,000 miles. March 6, 2026 NHTSA CAMPAIGN NUMBER: DP26001 OPEN INVESTIGATION All wheel drive allegation NHTSA Action Number: DP26001 Components: POWER TRAIN Opened From: March 6, 2026 – Present Summary The Office of Defects Investigation (ODI) received 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 contends that the interfacing splines between the transmission and the rear wheel drive power take off unit are failing. 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 results in a reduction of vehicle directional control. The Petitioner cites 48 complaints received by ODI alleging the same failure. ODI will evaluate these complaints to determine if they are related to the failure cited in the Petition and will conduct a technical review under 49 CFR Part 552. This Defect Petition is being opened to evaluate whether to grant or deny the Petition. The Petition can be viewed at NHTSA.gov under NHTSA Number 11712885.

The car threw several warning lights on the dash. The main indicator was that there was a problem with the air suspension: "Adaptative air suspension problem. Please see your dealer." The left airbag on the suspension then popped, rendering the car undriveable as the compressor would constantly blow air to try to inflate the airbag. The car was repaired at an independent facility at the cost of $2900.00 to replace the suspension airbag and the height sensor, as well as recalibrating ADAS. The car had 66k miles at the time of the incident.

2022 Acura MDX Transfer Case and Transmission Failure – Spline Shearing Description of Incident: I am reporting a catastrophic drivetrain failure on my 2022 Acura MDX. This failure occurred at approximately 50,000 miles. The vehicle initially exhibited a leak at the front differential/transfer case gasket. Upon inspection by the dealership, it was confirmed that both the transfer case and the transmission require complete replacement. This failure matches the technical details in the recently opened NHTSA Action Number DP26001. The interfacing splines between the transmission and the power take-off unit (transfer case) have failed, which is a known defect currently under investigation. Safety Concern: This defect causes a sudden and unexpected loss of all-wheel-drive capability. This results in a significant reduction in vehicle directional control and traction, particularly in wet or slippery conditions, posing an unreasonable safety risk to myself and my family. This occurred well within the expected lifespan of a modern powertrain. Resolution: The vehicle is currently undergoing a full transmission and transfer case replacement at the dealership under warranty.

ENGINE, ELECTRICAL SYSTEM
On several occasions, when the vehicle has been driving and comes to a stop in traffic. the auto start stop kills the engine when the brake is fully depressed. When we take our foot off the brake the engine will not start and a notification is shown on the dash. to start the engine push brake and ignition button. When we follow those directions the it does not start the engine. It usually requires us to release brake several times and continue to push start button. This issue has almost caused two accidents because we are stuck and the traffic behind does not see brake lights, because we have to release the brake. This occurred on the interstate in heavy traffic, and was almost struck from behind by a vehicle traveling at interstate speed, because all vehicles went around us and the upcoming vehicle did to see brake lights.
