The car had several warnings lights come on and immediately stalled out and stoped right in the middle of the road. The engine would turn over but would sputter like it was out of gas and would die after a few seconds. It stoped in the middle of a busy state highway in a curve. Luckily no one got hurt. I towed it to an auto service center. The 2020 Acura MDX suffered an in-tank fuel pump failure causing a low fuel pressure code (P0087). This model year is under a massive 2.6-million vehicle safety recall, but my specific VIN was omitted. It likely should be included before someone gets hurt.

On [XXX], while traveling at highway speeds on [XXX], the vehicle suffered a sudden, complete loss of engine propulsion. The vehicle rapidly decelerated, refused to respond to accelerator input, and forced itself into a dangerous "Limp Mode" in live traffic, creating an immediate highway safety hazard. Multiple warning messages illuminated on the dashboard. The vehicle was towed to Mile High Acura under Repair Order #[XXX]. Diagnostic testing pulled stored Code P0087 for Low Fuel Pressure at the Fuel Rail. An inline fuel pressure gauge confirmed that the low-side fuel pressure was rapidly fluctuating between 55 and 64 PSI at idle. The dealership escalated the data to the Acura Corporate Tech Line (Ref #[XXX]), which reviewed the vehicle's onboard snapshot data and officially determined a terminal defect in the low-pressure fuel pump assembly, mandating the replacement of the low-side pump and both fuel relays. Dealership service records confirm that this vehicle previously had a low-pressure fuel pump recall performed in 2021 under the federal safety agency Campaign Number 21V‑215 (Acura Code CAI). The sudden failure of this replacement component matches the exact failure conditions detailed in the subsequent the federal safety agency Campaign Number 23V‑858 (Acura Codes KGC/KGD). In that expanded campaign, American Honda Motor Co. openly admitted to federal regulators that the early replacement "service parts" distributed and installed during the 21V‑215 window were manufactured with the exact same defective, swelling density impellers prone to subsequent deformation and complete failure. Despite their own corporate Tech Line explicitly confirming that the root cause of this dangerous highway power loss was the low-pressure fuel pump—the exact component of the 21V‑215 and 23V‑858 safety recall campaigns—Acura Client Relations denied 100% safety remedy coverage. Acura refused to provide the technical basis for their denial in writing. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When accelerating into traffic (usually merging onto highway or changing lanes on the highway) my car will loose all power and fail to accelerate. This is extremely dangerous and has happened on several occasions. I have taken this into Acura as well as other automotive dealers and no one can seem to diagnose or recreate the problem. The only support I received from Acura has been a “software update & idle relearn”, which has never fixed the problem. I saw an the federal safety agency ID#23V85800 recall alert for Fuel Pump Failure, which perfectly describes the issues I’m having. Unfortunately, my VIN is not included in this recall. I respectfully request that you add my VIN to this recall so I can get my fuel pump replaced and hopefully resolve this very dangerous issue.

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)

Hi, Vehicle experienced sudden loss of power and inability to accelerate while driving. Engine entered limp mode and would not rev beyond approximately 2,000 RPM. Vehicle became unsafe to operate in traffic due to lack of acceleration. Dealer diagnosed fault code P0087 (fuel rail/system pressure too low) and confirmed failure of the high-pressure fuel pump. Vehicle had hard starting, delayed throttle response, and multiple warning lights related to engine, emissions, and drivetrain systems. This appears to be a fuel system failure affecting vehicle safety. Acura previously issued fuel-system-related recall(s) for similar vehicles, and this failure occurred despite prior recall-related service. Repair cost is approximately $2,400. Failure resulted in loss of engine power and posed a safety risk, especially when attempting to merge or accelerate in traffic. Vehicle mileage is approximately 160,000 miles.

I had a recall done by local Acura dealer, Miami Doral Acura, where they replaced parts that connected the engine to the car, they are like rods. I recently took the car to a mechanic because I needed to change the timing belt components and he advised me that one of the rods that were replaced failed. This means that the engine was attached by only one rod, the other rod was cut, not connected. I called Acura today reporting the issue with the recall, they gave me a case number 16125924, advising me that some one would get back to me. The same mechanic also advised me that the high pressure fuel pump was not working properly and that my car could stall while driving it and he advised that it would be dangerous to drive it without replacing it. The part he quoted me was around $700. I looked for recalls for this car with this fuel pump issue and found that Acura only recalled some VIN numbers and my car is not one of the VIN numbers recalled. I believe Acura has not recalled all cars involved with the pressure pump. I find it hard to believe that they are not aware of this issue affecting more of the 2018 MDX model. The recall with the rods failed just a year after they replaced them. I had the rod recall done in 1/25. I cannot drive the car until I have the mechanic replace the high pressure fuel pump and fix the problem with the engine rod recall. Acura needs to be heal accountable and compensate owners that are dealing with the same issue I am.
