   My 2016 Acura MDX (VIN [XXX]) is covered by Acura safety campaign 4170A8. The campaign covers rear subframe corrosion at the suspension mounting points that can cause the rear wheels to become misaligned or inadequately retained, affecting handling, stability, and braking. On XXX, I brought the vehicle to Sunnyside Acura, [XXX] (Repair Order XXX). The dealer did not perform the recall remedy and noted "cannot complete as rear toe arms are seized." They ordered replacement rear toe arms (52370-TZ5-A91 and 52375-TZ5-A91) that day. More than a month later, the recall repair has still not been completed: I filed a complaint with the dealership. They called me but did not follow through. On XXX, the dealer postponed the repair because no loaner vehicle was available. The repair was rescheduled for XXX. The dealer did not contact me. I contacted Acura Client Relations more than a week ago and have received no response. I am driving a vehicle with a known, open safety defect that Acura has acknowledged but has not repaired. I am asking NHTSA to help ensure Acura and its dealer complete the recall remedy promptly. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

   Heard a knocking noise in the engine, had it serviced at an independent mechanic (towed as to not create more damage and the knocking noise was louder). Mechanic told me that the rod bearing/engine had failed and would need to be replaced. $7000-$10000 for replacement. He also indicated that this was under recall for 2016-2020 cars. I checked my VIN and my car is not part of the recall but the car has 130000 miles and has been serviced regularly. I am requesting that it be part of the recall since this is a known/reported issue for this year/model. I called American Honda and they said because of the mileage and age, that it would not be part of the recall.

   "My 2016 Acura MDX completely seized on the highway after a loud knocking sound, which perfectly matches the connecting rod bearing failure under Recall 23V-751. Even if my specific VIN isn't showing up as open on the website, I know the NHTSA has a major open investigation into 1.4 million of these V6 engines because hundreds of vehicles are failing exactly like mine outside the original recall scope. I need Acura to open a corporate goodwill case to inspect my engine and cover this repair."

   "Vehicle experienced a sudden flashing check engine light pulled over checked oil restarted car flashing check engine light went away then started flashing again a few miles down the road (Cylinder 3 misfire) accompanied by severe engine knocking. The engine locked up/seized while hot. car was stuck on the road and was unable to shift to neutral. After cooling down, the engine restarted but produces a heavy metallic scraping and loud squealing noise from internal friction. This matches the exact failure mechanism of connecting rod bearing failure under investigation PE25008, but Honda/Acura has excluded this VIN from active recalls. I was forced to pay $389 out-of-pocket for an emergency tow."

   2016 Acura MDX. The red LED section of the inner tailgate taillight (lid light) has failed and no longer illuminates. The white backup bulb in the same assembly still works. The LED section is sealed inside the assembly and cannot be serviced, so the entire lid light must be replaced. This vehicle received safety recall M49 (NHTSA 19V-256) in 2019 for moisture intrusion into the inner taillights. The same failure has now occurred again. Honda's own Part 573 report for recall FLI (NHTSA 25V-259) states that the redesigned assemblies installed under 19V-256 do not sufficiently prevent moisture intrusion, and that moisture entered through two new pathways: between the gasket and the seal ribs of the lid light, and at the interface between the gasket and the body dust sealer. My failure appears to be exactly that condition. The NHTSA VIN lookup shows zero unrepaired recalls for this VIN. When I contacted Acura, I was told the issue was repaired in 2019. That response addresses M49, not FLI. I have not been able to get confirmation of whether FLI applies to this VIN or was ever performed. Loss of the rear position lights reduces visibility and is a citable equipment violation.

    I received a letter from Acura about a safety recall on the subframe. My car has been making a creaking noise and so I called the number on the letter. The guy gave me the number to Acura, Brookfield WI. I called and talked to someone there today, I think his name was John. I told him I wanted my car checked for the recall issue and I am worried about the noise. He said a subframe won't cause squeaking and I would have to pay $200 for them to look at it. I said I would call back in fall as the letter states but Im still wanting this issue fixed now.

18. Filed Jul 8, 2026Failure Jun 25, 2026Valley Stream, NYEngine, Steering, Suspension

    I am filing a safety and compliance complaint regarding execution of Federal Recall Campaign #26V365 by Valley Stream Acura and sales fraud by Paragon Acura. I purchased this 2016 Acura MDX from Paragon Acura on May 29, 2026. I have driven it only 550 miles, placing it strictly within the statutory New York State 60-Day Used Car Lemon Law Warranty window. A certified 6-page independent ASE forensic report documents that Valley Stream Acura bolted the federal recall brackets directly onto severely cracked rear control arms and rusted struts without disclosure. Furthermore, Paragon Acura forced a brand-new front control arm link onto a deeply pitted, scaling, and structurally compromised front steering knuckle to mask pre-sale defects, signing a false NYS highway safety certification. The vehicle was released to me with a bone-dry, empty engine cooling loop, creating an immediate fire hazard. Acura Corporate (Case #16437213) refuses to issue a corrective directive, willfully leaving a non-compliant vehicle on public roads.

    My 2016 Acura Max sha awd has 124 k on it and the other day I was driving down the road and my engine light went on than I lost power down to 20 mph and heard a knocking noise from the engine like the rod bearing broke or something I’ve noticed the recall on the engine for some Acura 2016-2025 3.5v6 engines but Acura is saying my model car was not in the recall list which I can’t understand why if it has the same engine 3.5 v6 with the same rod barring issue as the ones on the list being recalled . The issue is with all 2016-2025 Acura Mdx models that have the 3.5 v6 in it .
