NHTSA Complaint #11662240 — 2016 ACURA MDX

***THIS IS A RESUBMIT WITH CORRECTED INFORMATION*** I purchased a used 2016 Acura MDX from a family member, and shortly afterward began experiencing a rhythmic metallic knocking noise under load, particularly at low RPMs (e.g., accelerating in low gears or when the engine is bogged). The noise is not present at idle or during coasting, and it closely matches the symptoms described in recall 23V-751, which addresses premature connecting rod bearing wear that may lead to engine failure in certain Honda and Acura vehicles. However, my vehicle’s VIN is not included in the existing recall. The knocking has persisted across several thousand miles and multiple oil changes. I recently inspected the drained oil and found metallic sparkles/particles, which may indicate active bearing wear. There has been no Check Engine Light, and the vehicle has received on-time oil changes using high-quality synthetic oil, with immediate mechanical inspection when the noise first appeared. I know for certain the previous owner maintained the vehicle properly, as he is a family member and I occasionally helped with maintenance myself. Based on the symptom pattern, operating conditions, and consistency with the failure mode described in 23V-751, I believe this vehicle may be affected by the same underlying defect, but is excluded due to an overly narrow recall scope. I am submitting this complaint in support of Recall Query RQ24-013, which is currently under review to determine whether Honda failed to include all affected vehicles. I am concerned this poses a long-term safety and reliability risk, and that vehicles like mine are being improperly excluded from coverage. It is available for inspection. I am deeply concerned for my significant other to drive my vehicle in any capacity, and myself as well. I have videos as well. Please reach out if you need them because the bearing has not spun out yet.
