Purchased great condition used 2019 Fit EX on XXX from local non-Honda dealership. Nearly 10 months later, on XXX the following errors appeared on the dash: tire pressure monitor system, emissions, hill start assist, lane deviation warning, power steering, and vehicle stability assist errors on the screen, and the check engine, tire pressure monitoring system, vehicle stability assist system, and electric power steering lights were also on. I took it to a local Honda service shop (Performance Kings Honda at [XXX]), and it was diagnosed as needing fuel injectors replaced (running too rich). I approved the repair for a total cost of $1,629.32, including the diagnostic fee, parts, labor, and taxes, on XXX. This was an identical issue to a used 2018 Honda Fit EX that I had purchased on XXX which had the same symptoms and was diagnosed as the same problem (fuel injectors) in XXX, and for which I submitted a separate the federal safety agency complaint. This is an issue for the federal safety agency because it is a known issue on this make and model of car by owners and Honda. See the following: Honda Service Bulletins 21-007, 22-002, 23-042. Additionally, it's an issue I have had to deal with twice, on two separate vehicles, both of the same make and model, meaning it is likely an extremely prevalent issue for owners. Fuel injectors are an expensive repair, and they're known to be faulty on these vehicles by the manufacturer. Without correction, other major systems in the vehicle will fail, with issues such as engine misfire, overheating, catalytic converter failure, and catastrophic damage to the engine. Honda already knows this is an issue on the 2016 and 2017 models. The warranty extension they already issued for these years must be expanded or replicated to cover this issue, which has persisted in the 2018-2020 models. This should be expanded to cover additional years as well. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Purchased great condition used 2018 Fit EX on [XXX] from local non-Honda dealership. The next day, on [XXX], the following errors appeared on the dash: tire pressure monitor system, emissions, hill start assist, lane deviation warning, power steering, and vehicle stability assist errors on the screen, and the check engine, tire pressure monitoring system, vehicle stability assist system, and electric power steering lights were also on. Returned to the used dealership that same day. They replaced the spark plugs and battery, still not solved. Took it to local Honda service shop (Performance Kings Honda at 9131 Fields Ertel Rd, Cincinnati, OH 45249), diagnosed as needing fuel injectors replaced (running too rich), and got the fuel injector repair. Got the car back within a week, problem now solved. This is an issue for the federal safety agency because it is a known issue on this make and model of car by owners and Honda.

On June 10th 2026, my 2020 Honda Fit EX-L with approximately 20,000 miles began misfiring while idle at a light. Error codes started appearing on my dash, no check engine light. Honda of Short Pump diagnosed a cylinder 2 misfire (DTC P0302) caused by a carbon buildup on the intake valves and quoted ~$1200 for valve cleaning. This is the identical failure mode described in Honda Service Bulletin 21-007, whose affected vehicles list includes 2015-2020 Honda Fits, and which Honda covers under warranty extension bulletin 23-042 for 10 years/150,000 miles - but only for 2018-2019 model years. My 2020 vehicle is excluded by VIN range despite an identical defect at far lower mileage. An engine that misfires and loses power in traffic is a safety hazard. American Honda case #16419709 is open. See related complaints 11462041, 11490506, 11549767, and 11593466 from other owners outside the covered VIN range.

Multiple warning lights lit up after starting car and driving for a short distance (less than 5 feet). Honda mechanic diagnosed it as a misfire in cylinder likely due to carbon buildup or other unknown reason. Similar incidents have happened with other 2019 Honda Fit and an extension of warranty was issued for some vehicles but not all (SB 23-042). Unfortunately, mine was apparently not covered despite the same exact issue as other reported incidents.

Before getting the recall completed on this 2018 Honda Fit I was experiencing the engine misfiring and engine stalling while driving as well as many warning light illuminating on the dashboard. When taking the vehicle to the dealership they found out that I needed a recall completed for the fuel pump so this may have been what was causing the engine misfiring, stalling, and illuminated warning lights on the dashboard. But, because I was experiencing a misfire they went ahead and charged me for a diagnosis so they can make sure there are no other issues going on. So after performing the recall on the fuel pump replacement the dealer technician says there in an active engine code and says its P0301 for engine misfire and with further checking says I need to replace a four fuel injectors with only 85,000 miles on the vehicle. Since this was the initial cause of the issue I thought this would be a recall as well but the dealer said it was not and wanted to charge me for replacement of all four fuel injectors. I believe since this is the same issue in regards to safety that they should be covering this under warranty or forced/voluntary recall. I would like there to be an investigation into this issue since this seems like a design flaw from the manufacturer which when reading the fuel pump recall says "the fuel pump failure can cause an engine stall while driving, increasing the risk of a crash" which describes the ongoing issue I have with my vehicle after the safety recall was completed.
