NHTSA Complaint #11685908 — 2017 ACURA MDX

On [XXX], while driving at approximately 50 mph on [XXX], the vehicle experienced a sudden and complete loss of power accompanied by severe shuddering. Multiple warning lights illuminated on the dashboard, including the check engine light. The vehicle would momentarily regain power before failing again. This created a significant safety hazard, as I was unable to maintain speed or accelerate safely in traffic. The vehicle was immediately taken to Team Gillman & then transferred to Sterling McCall Acura located at Houston, TX. The dealership diagnosed a catastrophic internal engine failure, originating from the bottom end, requiring a full engine replacement. The vehicle's mileage at the time of failure was approximately 142,250 miles. This critical failure occurred without any prior warning. I am aware of NHTSA Investigation Number ODI PE25008 regarding faulty connecting rods in certain Acura and Honda vehicles, which can lead to sudden engine failure. While my vehicle's VIN was not included in the initial recall population, its symptoms and failure mode are identical to those described in the investigation. I requested that Acura address this known defect through a goodwill repair, given the clear correlation to an ongoing federal safety investigation. This request was formally denied June 2025. Given that the NHTSA has expanded its investigation to include additional vehicles and model years, including that of my MDX, I am filing this complaint to ensure my vehicle and its specific failure data are included in the official NHTSA record. Urge the agency to compel American Honda Motor Co. to expand any subsequent recall to include my vehicle and others with identical failure patterns. The sudden nature of this engine failure presents an unacceptable safety risk to the driver, passengers, and the public. Thank you for your attention to this matter.
