2019 Honda Fit ENGINE,FUEL/PROPULSION SYSTEM

All warning lights cycle through on vehicle dashboard after turning on vehicle. Vehicle was taken to Honda Auto Service Center, where issue is diagnosed as Carbon Buildup, causing misfires. Error Diagnostic Code is one of P0300 - P0304. After maintenance, error clears out. However, there is a Honda Service Bulletin 23-042 which provides a warranty extension for Honda Fits of the same year, make, and model with the same issue, which my vehicle's VIN was not included as eligible. Issue of carbon buildup causing misfires may apply to other VIN ranges than in that bulletin, as accounted by NHTSA ID #11462041, #11490506, #11549767, and #11593466

Four dashboard warning signs (Check Engine Light, Tire Pressure Monitoring System, Vehicle Stability Assist System, Electric Power Steering) appeared all at once suddenly. I had the vehicle towed to my local Honda dealership. They gave me a diagnostic code of P0304 and insisted that the repair did not fall under my car's active warranty. I searched the web and found it is a common problem in Honda Fits. Some 2019 Honda Fits have an extended warranty for fuel injection replacement, but it is not applicable to my car for an unknown reason. Relevant service bulletins: 23-042 and 21-007.

Fuel injector is going bad on my car at 80,000 miles causing catalytic converter to go bad based on two check engine codes. Recall done on 2015-2016 models so hoping this could be extended to 2019 as it seems they haven’t fixed the issue

While driving the emission system problem warning came up on my dash with the check engine light. After this happened it became incredibly hard to accelerate the engine. I was driving on the freeway and attempting to merge putting my life and my families at risk because the engine was trying to accelerate but sputtering and stopping for a moment instead. It hasn’t been inspected by police, but went to dealer and got code P219A and was told this was a faulty fuel injector. This was the first time this had happened and no other warning lights came on before the emission system problem that popped up on the dash.

Fuel Injector failure in under 35,000... There is a misfire from one of the fuel injectors leading to a replacement of the entire system.

Engine light came on and it was brought to the dealership and I was told all fuel injectors need to be replaced and it wouldn't be under warranty. The car has 65,000 miles on which is just over warranty, but I should still not have had to replace these yet. There have been other problems with the fuel system with the fuel pump recall and they have extended the warranty on fuel injectors in other Honda vehicles, which leads me to believe this is a greater problem than just my car and it should still be covered by Honda.
