NHTSA Complaint #11666805 — 2015 HONDA ACCORD

I own a 2015 Honda Accord EX-L V6 3.5L that I purchased brand new from the dealership with zero miles. I’ve taken excellent care of the vehicle, and because I typically drive short distances, it only has 93,000 miles as of June 2025. Despite the low mileage and proper maintenance, the intake manifold plenum (part #17160-5G0-A00) now needs to be replaced due to significant deterioration. The material used for this part is poorly made, it corrodes and breaks down over time, causing vacuum leaks. This is a well-documented, widespread issue in Honda vehicles globally. In my case, the deterioration has caused performance and safety concerns and has rendered my car undrivable. To make matters worse, this part is on national backorder with no estimated delivery date. I’ve contacted numerous dealerships and suppliers with no success, leaving me without a working vehicle or timeline for repair. I rely on this car for transportation, work, and daily responsibilities. It is extremely frustrating that a critical engine component is both defective and unavailable, especially when so many other Honda owners are facing the same problem. I am filing this complaint to raise awareness and request a timely investigation and resolution.
