NHTSA Complaint #11589623 — 2016 ACURA MDX

I am writing to bring to your immediate attention a critical safety issue with my 2016 Acura MDX, and the subsequent exclusion of my vehicle from a known recall that directly addresses the problems we are experiencing. Without any prior warning, we began hearing a fluttering sound coming from the engine whenever we accelerated. This noise progressively worsened and evolved into a pronounced knocking noise.Concurrently, the vehicle became increasingly sluggish and heavy, resulting in significant difficulty when accelerating. Despite these alarming symptoms, the vehicle's temperature gauge showed no changes, there was no smoke or unusual smells, and the check engine light did not activate. Gravely concerned for our safety, we promptly took the vehicle to our local mechanic for a thorough inspection.The diagnosis revealed significant engine damage, specifically to the connecting rod bearings and the crankshaft. Given the severity of the issue, we then brought the vehicle to the closest Acura dealership, Pohanka Acura. The service advisor informed us of a recall affecting the engine and rod bearings in the 2016 Acura MDX model. They also confirmed that our vehicle's engine was indeed damaged due to the same rod bearings and crankshaft issue described in the recall. However, despite this clear evidence, we were informed that our vehicle's VIN was excluded from the recall repair. The technician who performed the diagnostic on our vehicle recommended a new short engine block, which is was concerning especially since it mirrors the known recall issue. I am requesting that the NHTSA urgently investigate this matter. I hope the NHTSA treats this issue with the utmost urgency and seriousness it warrants. The safety of Acura MDX owners is at stake, and immediate action is essential to prevent further incidents and ensure our safety. Thank you for your prompt attention to this critical matter. I await your swift response and resolution. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA),
