ENGINE
2004 MDX had digital screen problems where the screen remained black upon starting, which was hazardous as I couldn’t tell how fast I was going. After 3 visits to the dealership they identified the problem and fixed it Also, in a separate instance, car stalled after trying to start up after stop signs or while waiting in traffic several times. Could have been rear ended or worse. Dealer replaced the starter at 30k miles. Still had the same issue after this and they say the car is fine.

ENGINE, FUEL/PROPULSION SYSTEM
While driving my 2020 Acura MDX A-Spec at approximately 63,744 miles, the vehicle suddenly lost all engine power without warning while passing through a busy multi-lane intersection. The loss of propulsion prevented acceleration and forced us to coast across traffic lanes to reach the shoulder, creating a significant safety hazard. The engine would not restart. The vehicle was inspected on 3/17/2026 by Lyle Pearson Acura (Boise, ID). The dealership diagnosed catastrophic internal engine failure with the following findings: spun rod bearing in cylinder #6, excessive metal debris in the oil pan, and bearing seizure to the crankshaft. The technician stated the failure pattern is consistent with the rod-bearing defect described in Acura Safety Recall / Service Bulletin 24-001. Although my VIN is NOT currently included in the recall population, the confirmed failure mode matches the known defect. This suggests the issue may extend beyond currently identified vehicles that are included in Acura Service Bulletin 24-001 and NHTSA recall 23V-751. The vehicle has a salvage title from prior cosmetic damage only; no engine, drivetrain, or structural components were affected. The vehicle has been properly maintained with documented service history. This failure represents a serious safety risk due to sudden loss of power in active traffic conditions, increasing the risk of collision or injury. I request NHTSA review this incident to determine whether additional vehicles should be included in the recall and to assess the broader safety risk.

AIR BAGS
While driving at 25 miles an hour on a smooth curving road out of a housing area my wife who was driving and my grand daughter in the front passenger seat heard a loud boom that sounded like somthing hit the roof. My grand daughter looked into the back passenger area and said she saw a large buldge in the headliner near the back window on the drivers side. My wife continued driving saftly to the nearest parking lot and parked the vehicle, she got out and inspected the roof and found no dammage of any kind. she opened the back window tail gate and saw a large fist size buldge in the headliner near the open area on the drivers side. She had no idea what happened. There were no waring lights or indicators that indicated a problem and she drove home and showed it to me. When I saw it I thought it was a rear window or curtian air bag that tried to deploy but did not break through the headlinner. I have called the dealer and scheduled an appointment to check it out on thur March 26 at 09:00 2026. I verified that there are no indicators or warning lights that indicate a problem. The service department said it should be safe to drive until then.

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.

AIR BAGS, UNKNOWN OR OTHER, ELECTRICAL SYSTEM
On 11.25.25, my MDX was involved in a multi-car hit and run on highway 101 SB at the Laurel Drive off ramp. The vehicle sustained two points of impact: (1) substantial front/driver side impact (2) rear-passenger side impact. Despite the severity, location of impact and speed of travel at the time of the collision, all airbags deployed except for the driver side curtain airbag. Importantly, at the time of the crash, the Lane Keeping Assist System (LKAS) and associated AcuraWatch driver assist systems were activated. The vehicle’s safety assistance technology was engaged and functioning immediately prior to impact. Considering the above mentioned facts, driver side airbag failing to deploy, raises serious concerns regarding Possible software or signal-processing malfunction or electronic communication between radar/camera systems and the SRS module. The nature and severity of the impact clearly met deployment criteria for the driver side airbag. This failure raises concern that there may be a defect in the SRS system, including but not limited to: Airbag inflator component or propellant issue. Supplemental Restraint System (SRS) crash sensor calibration. SRS control module deployment logic. Crash signal sensors. Event-trigger logic or interconnnect failure. Wiring harness or inflator defect. Whether the system registered steering correction or impact prediction, the failure to deploy increased my risk and resulting injury, as well as compromised the fundamental safety system designed to protect drivers in front-impact crashes.

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.

SUSPENSION
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.

ELECTRICAL SYSTEM, EXTERIOR LIGHTING, SERVICE BRAKES
Hello, My 2018 Acura MDX has moisture and water inside the inner tailgate (trunk) tail light assembly, which caused the light to stop working. I understand there is a recall affecting some 2014–2020 Acura MDX vehicles related to moisture entering the tailgate light assembly, and my vehicle appears to have the same issue. Recall link: [XXX] Last week I visited the Acura dealership(Acura Columbus) in Dublin, OH for a fuel pump recall service. During that visit, the technician also noticed the water inside the inner tail light but quoted about $750 for the repair. Although my VIN does not show this recall, my vehicle is experiencing the same problem described. Could you please review and advise if this may qualify for recall coverage or goodwill assistance? Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

EXTERIOR LIGHTING
The rear lighting on the left side of the tailgate was accumulating water. Even though it was part of a recall campaign, the period had expired. I had to replace it at my own expense. This could be a broader issue since similar cases may occur for others.
