2018 Honda Fit: check engine light

Filed Jun 25, 2026 · Engine, Fuel system · OH

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. See the following: Honda Service Bulletins 21-007, 22-002, 23-042. 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.

My vehicle has been inoperable since 2023. The dealership refuses to repair the fuel pump and all other issues, per the manufacturers recall. Steve Allain at Honda of Covington reported to me that the vehicle would not re-start if turned off. The leadership at the dealership (Kyle Mitchell) and Courtney Gullien communicated to me that the car was operable and the fuel pump was repaired, but will not provide service records that document this information. Tim in the parts department has communicated to me multiple times that no one from the dealership has ordered any parts related to the fuel pump recall for my vehicle. The manufacturer refuses assist with this matter and send someone from corporate to inspect the vehicle after multiple requests. The check engine light provided warning, along with a loud burning smell from the vehicle. The insurance company also refused to send a representative to inspect the vehicle. The issues with the stalling of the vehicle, not starting upon turning the key, and foul smell has been an ongoing issue since purchase. The previous dealerships claimed that they repaired the vehicle. The fuel pump is the component that has been failing. The vehicle has been inoperable and at the dealership since April 2023.

Check engine light with Code P219A. Honda dealer performed a cylinder A/F Imbalance test and recommended that the Fuel injectors be replaced. This appears to be a common problem with Honda Fits. The injectors are just as bad the recalled 30520-5R0-013 injectors. Honda claims the 2018 vehicles do not have those injectors. I beleive this vehicle has the same defective 30520-5R0-013 injectors.

Misfire codes that indicate a bad fuel injection system, including issues with previous models for the same issue. My car was running very roughly and stuttering at high speeds. An independent garage confirmed that the car had bad fuel injectors at only 80,000 miles and it cost $950 to fix. I had 6 check engine lights appear from this issue. Honda refuses to acknowledge or do anything about it.

Car is not running properly. Idling very poorly. Check engine light is on. Check engine light code is P0300, P0301, P0304. Honda has issued extended warranty for the same make/model(2018 Honda fit). My car's VIN is not included. Spoke with Honda corporate. No explanation for this.

VSA, power steering, engine light, and tire sensor light all came on at once. The car was not steering properly. I took the car in May 16, 2024, and they determined that a carbon buildup in the engine was the cause, and said the cylinder also had a misfire. They also said that the car needed a software update. I asked about the recall, because the recall letter I got in the mail states that if the engine light comes on, then it is eligible for repair. But they refused to repair it, claiming that the issue was only due to the carbon buildup, and said they have no parts available. However on my invoice when picking up the car, they listed the recall as if it were part of the repairs. I asked, just to verify, if they repaired it and they said no. I called the Honda number on my recall letter, and they spoke with the main manager at the dealership and told me that they determined the issue with my car wasn't due to the fuel pump recall. So do I have to drive my car until I have issues/until the engine is damaged by this safety issue? That doesn't make sense.

Recently, our check engine light came on. We had the code tested and it came up with cylinder misfiring(P0300). Upon doing some digging I noticed that Honda has issued an extended warranty of 10 years 150,000 miles for 2018 Honda Fits experiencing the same code but for some reason mine's not included. I'm happy to bring it to a dealership to confirm the codes but if it is that same issue I would like to know that it will be treated like all these other 2018 Honda Fits. I've tried to get this resolution from Honda but have gotten no help.

At 74k miles my check engine light came on randomly. Took the car to a mechanic, who turned the light off and advised me to tighten the gas cap. A few weeks later the check engine light came back on. Auto zone said a spark plug needed replacement. About a week later the check engine light, along with many other lights came on. After a lot of research I learned that there is a recurring issue with Hondas (plural) and their fueling system due to direct injection. Leading to misdiagnosis, replacing unnecessary parts, only to be left with a check engine light. Luckily, I received a letter from honda informing me of the warranty extension for certain Fits due to carbon buildup and misfires. I took my fit to the dealer and shared my concerns with the service advisor. I took it to the experts in hopes that if it was a misfire with a DTC of P0300-P0304, they would surely get it right the first time. A few hours later I was informed they found DTC P0420, meaning the catalytic converted needed to be changed. Ignition coils were also faulty, therefore affecting the catalytic converter. CC was covered under the emissions warranty but coils were not. They could not/would not replace the CC unless I agreed to replace the coils. Despite me sharing my concerns the advisor failed to mention the DTC for the coils, which turned out to be P0304. I replaced the coils and CC, paid $885. When I read the invoice and saw DTC P0304, I got upset and asked a different advisor why the carbon cleaning wasn’t performed instead of changing the coils. I was told there wasn’t enough carbon buildup to be the root of the problem and that the technician had years of experience and I could rest assured there was no other way. Fine. I take the car, less than 48 hours later, my check engine light comes on again. I take the car back. This time I am told the car is showing DTC P2198 and they recommend replacing the fuel injectors and fuel pipe! No DTC misfire, so unable to perform carbon cleanup.
