I have a 2018 Honda Fit. I am meticulous about maintenance. In November 2019, at 31,000 miles several indicator lights came on. The check engine, TPMS, Vehicle Stability assist, Electric Power System. The car was running smoothly but I was told by a Honda dealer there was excessive carbon build up. The cost to clean it out would be $500. They claimed that because this was caused by an outside element and a part had not failed that the warranty would not cover this. I fought it and they did a one-time courtesy repair at no charge.

June 2021, 51,000 miles several indicator lights came on. The check engine, TPMS, Vehicle Stability assist, Electric Power System. Car running smoothly, no hesitation, no misfires. Different Honda dealer told me it was excessive carbon build up on manifold and this time it would be $604 plus tax I asked if there was a maintenance service that would prevent this from happening and I was told no. That the fuel system service offered does not reach the areas of the engine where the carbon builds up. The dealer claimed the problem stems from chemicals in the gas.

Clearly there is a flaw in the direct injection engine design that Honda has known about for years and does not want to take responsibility for. This is unacceptable and Honda is committing consumer fraud by knowingly selling a flawed product that jeopardizes the safety of their customers.

I do not feel safe driving this car with these failures in the engine, not knowing when this problem is going to happen again and facing an expensive repair bill every time it does happen. Not to mention the inconvenience of being without a car for several days while it is being repaired.

Honda has lost a customer forever.

I started noticing a misfire transmitted through my seat and foot pedals. I contacted Honda and they said they could get me in in about 2 weeks. The very next night, just after I started the engine, I got 4 lights on my dash. The check engine, EAPS, TPMS and TCS lights.I took the car in the next morning. The dealer was very good about the whole thing. They put in a new set of injectors, est the valve lash, checked all of the wiring, coils and plugs. Nothing was working. They put in a tech assist case and Honda told them to replace the cylinder head. We will see how that goes.
