Three instances of engine misfiring, causing the car to immediately go into a speed limiting mode during driving. This is a major safety hazard and can happen in the middle of high speed driving. The first instance was a 52K miles, second at 69K miles, and third at 130K miles. The most recent instance resulted in the spark plug ejecting from the cylinder head, melting into the coil pack, and stripping out the cylinder head thread. This resulted in a costly repair.

Driving down the highway the spark plug was blown out of the engine head and the car lost power immediately. The car has approximately 12,000 miles and all OEM parts from the manufacture. Maintenance was kept up on the car. This is extremely dangerous since this highway is usually busy with cars and tractor trailers. My son was in the left lane and was almost hit by a tractor trailer due to the violent explosion of the spark plug being blown out of the engine. In addition, was unable to get over to the shoulder of the road and had to stop in the left-hand lane on route 80 in NJ which is very dangerous. Both of my sons were in the car when this occurred. The car was towed to my licensed mechanic who confirmed that the spark plug was blown out of the engine which caused the loud noise and loss of power. There was no warning, symptoms or messages before this occurred which is why I am extremely concerned for the safety of others who own this type of vehicle.

A spark plug on the third cylinder blew out and stripped the threads on the cylinder. The blow out caused an electrode to break off and damaged one of the valves. I made honda america aware of the problem and asked them to honor a "goodwill" warranty since, despite being two years outside of the warranty, my car only has 44,000 miles on it and this is a known issue with this make/model of car. Honda refused. The total cost of repairs will likely be $4,000.

Driving on highway at 60 MPH when I heard a loud "pop" and it sounded like my engine had blown a hole in it. I had it towed to a honda dealer who told me the spark plug blew out from the cylinder head - stripping threads completely. This is a known problem being talked about by many people on honda fit forums. This is the second time this has happened to my car. The first time it happened the plugs just came loose and burned up one coil pack, but it did not blow out the spark plug. The gen 2 honda fits have a problem with their spark plugs coming lose. I was told by the honda dealer I needed a new cylinder head, coil, spark plugs, and head gaskets. Honda is denying many fit owners coverage under warranty due to this problem. I have less than 80,000 miles on my car and it was purchased in 2013 as a certified honda with a 100,000 power train warranty. This needs to be covered in full as a warranty claim through honda USA. I have attached a picture that was taken to show the burned up coil pack.

I brought my honda fit 2012 to my mechanic with issues of a misfire in cylinders 1 and 2. He thought it was a simple replacement of the spark plugs (only 51,000 miles on the car) and maybe a coil pack replacement. Once he removed the spark plugs from cylinders 1 and 2, he saw the tip of one of the spark plugs ground had broken off into the cylinder head and the coil packs and spark plugs were worn and covered in a blackish soot. He informed me that this meant that the spark plugs has wiggled loose over time and extreme pressure had caused this issue. And since no one has ever touched my engine, beyond a honda dealership for an oil change, that this was a manufactures defect when installing the plugs in the first place. All the movement caused the threads to wear away on cylinder 2, so I took to my local dealership thinking it would be covered by honda, but they less than helpful. They stated my mechanic had no idea what he was doing, and did the damage. They said there are no current recalls or campaigns, but it took me 10 secs on the internet to find tsb's issued by honda, nothing the exact same issue I am having! This has put me in a fight with honda of america to cover this very costly repair.
