NHTSA Complaint #11630971 — 2015 HONDA PILOT

We were on our way out of town in May 2022 when the car suddenly idled and wouldn't go past 35 mph. The spark plugs would constantly need replacement and we bought a connector which seemed to make them last longer, but eventually still burn out sooner than they should've. We've had diagnostics through friend mechanics and family and cylinder 2 was the main culprit. We took the car to honda recently and there is valve repairs that need to be done, to include all necessary gaskets, water pump and tensioner. There's also need to replace power steering pump, bushings and vtec spool valve. There were no prior indicators, the engine light suddenly came on when the car idled and riding on the highway at 35-40 mph was not very fun or safe. We've left the vehicle in the garage since the malfunction as is since we had other vehicles until we saved funds for the fix. We just didnt think it'd be this high of a cost and granted the car is only 98,800 miles in, i just dont understand how this all could be when my honda accord is 255k and still in good shape with no major fixes... Any insight would be greatly appreciated.
