2021 HONDA CIVIC Fuelpropulsion System Problems

Our battery died in April 2025. We've had this car since October 2021 with only 8 miles on it. We've replaced: The PCV valve The PCV valve tube The MAF sensor The sparks plugs 3 times which was $90 each time Replaced our battery 2 times since April 2025 3 oil changes And finally replacing our entire fuel injector system with the hard fuel line. And replacing the battery the first time is what revealed all these issues because we kept getting codes on our obd-ii scanner of P0172, U0038 and U0100. Honda told us once the fuel injectors were replaced then our car would be fixed but that is not the case. The car can't travel further then 5 minutes before the spark plus burn. We replaced the spark plugs on Sunday morning and we went to the store and they were charred after that drive same day.

The 2021 Honda Civic experienced an emission system failure at 70,000 MPH and detected fault code p0340, possibly an injector failure

I was notified of a Safety Recall by American Honda regarding the fuel pump module. I contacted to dealership and they are stating they will not have a remedy within a reasonable time period (60 days), rather they will have the parts available for a remedy in the fall of 2024, which is over six months away. Per the recall information provided on this website, they are supposed to have a way to fix this issue within 60 days from the date I contact them, but they won't even offer an inspection to see if the defect exists on my car.
