NHTSA Complaint #11635997 — 2016 HONDA PILOT

We have always taken great care of our Pilot, regular oil changes, tire rotations, checking the fluid levels. Just before we went on vacation, our Pilot's check engine light came on and started blinking under normal driving conditions. When we hooked up the code reader, it was for a misfire in the second cylinder. Having changed the spark plugs about 30-40k before this incident, we tested the plugs and assumed it was the coil. We changed the coil. After returning from vacation, we drove the car minimally yet after about 40-50 miles, the code returned with knocking sound. We had the car towed to our residence...to find the same code. We inspected the plug and coil, no issues were present and the code was cleared. The next day, the code came back on and the engine was knocking very loud and had definite performance issues. I checked the Honda recall page and our car had no open recalls. I noticed that other Pilots with the V6 engine in our model year range were included an investigation by the NHTSA. Our mechanic drove our pilot for 30 feet and immediately called me to tell me that he would not suggest even spending money on diagnosing the problem....as he believes the engine is a total loss. It seems unfair that Honda would not address this issue as it seems a wide spread problem after a simple google search.
