NHTSA Complaint #11430269 — 2018 HONDA FIT

I purchased a new Honda Fit in 2018. 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 and the same thing happened all over again. 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. This is a problem with Direct Injection engines. 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. I have documentation to back all of this up.
