2018 HONDA FIT Fuel/propulsion System Problems

There was a warranty extension for carbon buildup on the fuel injectors and I have taken my car to Honda twice to get the carbon removed and the software updated to fix the problem of multiple codes coming up. I took the car on Friday September 19, 2025 and I picked up the car at 3:30pm in September 20th. The person assisting me said they removed the buildup and fixed the software but at 11pm on the 20th, all the light came back on, indicating the problem was not fixed. I drove about 75 miles after getting my car back when the problem happened again. This has been incredibly unsafe for multiple reason. 1. When all the car dash indicators turn on, you can’t tell what the tire pressure is and if there are any problems. I have been having to manually check the tire pressure every few weeks because this is an ongoing problem and it causes the tire pressure gauge to not work 2. Because this is ongoing, you cannot reset the oil change maintenance indicator, so it is much harder to track when an oil change was last done. This has caused me to miss vital maintenance required to keep the car running well. 3. It is incredibly inconvenient to have to take the car to be fixed for the same problems multiple times. It costs consumers vital time, and potentially money without seeing any actual improvements. Although the diagnostics fee has been waived, having to potentially pay up to $200 in diagnostic fees makes consumers like me not want to take it for fear that may be very costly to even have them take a look at the car, thus making it less likely people will take the car in for necessary and important safety fixes. If you would like to see any records or inspection the vehicle, please feel free to reach out. The only fix I have been offered is to replace the fuel injectors for $1600, without any guarantee that it would fix the problem. I also took this matter up with Honda corporate, without any real solutions and there are multiple reports online of repeat problems.

Earlier today I paid $2,605 to have 4 fuel injectors replaced on a 2018 (75,000 miles) Honda Fit at Davis Honda in Burlington New Jersey. I see that earlier Honda Fits have a service bulletin/extended warranty on the fuel injectors that would have covered me [XXX] ). I also see that many of their other 2018 cars have service bulletins for similar fuel injector issues [XXX] ). It appears that this is a widespread issue that Honda should be addressing. Is there someone I could speak to about this? This is not Honda quality. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Honda is not replacing the fuel pump on these vehicles. They are stating that the fuel pump has to fail before they replace it. If the fuel pump fails while someone is driving on the highway, there is a strong likelihood that they could crash. Honda has sent out recall flyers to take your vehicle to any local dealer and they will replace it for free. I have called every dealership within 50 miles of the D.C. area and none will replace the recalled fuel pump until the car breaks down.

Fuel injector failed and sluggish drive

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.

I took in my car for the fuel pump recall on October 4th at Clawson Honda Fresno. I took it home the same day and the next day my car was stalling and shut off on me. I took my car back to Clawson Honda on October 8th and they scanned it and said the fuel pressure was low. They cleared the codes that they claimed were unrelated to the recall and wanted to charge me 390 for diagnostics. I refused. My car is still stalling in the road and many of the dash lights come on. The car wont let me accelerate. I took it back to Clawson Honda October 30th because this issue was not present prior to the recall. We just received a call that the fuel pump that was replaced is making the other components work harder which is causing it to stall. This is all clearly caused by the recall but they want me to pay 1500 out of pocket to have it fixed. Which is unfair. I submitted a complaint to Honda corporate but they still say we have to pay dealership fees. My car was working fine before the recall and Im frustrated that it was returned to me in worse condition. This was all because of the recall fuel pump and the issues are all connected so I shouldnt have to pay.

Honda placed a recall for the fuel pump on my vehicle and did not notify me. I was notified by my insurance. I have had many issues caused by or related to this recall that they have refused to fix or remedy. They want me to pay out of pocket and they have completely delayed fixing my recall. They tell me the part is unavailable and they will call when available and then tell me they still don’t have it after 90+ days. They are refusing to replace the catalytic converter even though that’s the error code coming up and I am under the federal warranty for it. They are trying to charge me to fix my fuel injectors for the second time in less than a year and won’t cover the cost even though it could be a direct connection to a faulty fuel pump.

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.

Multiple warning lights came on at the same time. OBD reader showed code 0302 (cylinder 2 misfire). Dealer performed warranty extension program to media blast the inlet valves. This was unsuccessful and the dealer now suggests that all 4 fuel injectors need replacing. The car has recorded 45k miles since new in 2018.

I received notification of a recall regarding the fuel pump on my 2018 Honda FIT. Now, six months later, I contacted my local dealership to get other work done and asked, again, for the recall work to be done. Honda refuses to do the work or even tell me when it will be able to do the work on my car to correct the problem. I use my car every day for my work, and I am increasingly concerned that my car will fail, leaving me unable to work without the added expense of getting a rental car. Six months should be plenty of time to, at the very least, figure out when they will be able to do the work.

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.

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.

I have called several times to the Howdy Honda dealership where i purchased my Honda fit . the response is the same each time that they have not released the Fuel Pump. I have been having issues with my car that is hesitating when i drive and takes a long time to get going up a hill or just even a flat road.

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.

THIS IS MY SECOND SUBMISSION!!!!!! PLEASE HELP!!!! 2018 Honda Fit Saleena - 1:39 pm EST Submitted for the formal complaint about the harassment and discrimination related to All honda dealerships, Kyle Mitchell and Shakaia (Rep from previous call). Case Management / and Supervisor is reviewing. If the manufacturer has failed or is unable to remedy this safety recall for your vehicle in a timely manner, Please contact the NHTSA Vehicle Safety Hotline at: 1-888-327-4236 or TTY: 1-800-424-9153 or file an online complaint with NHTSA. My company vehicle has fluid leaking on the floor, the check engine light constantly coming on, the rear camera is intermittently inoperable and it smells like something has died in it (mold/mildew). Since I have owned the vehicle, I have reported these issues to Honda dealerships and they have claimed to fix the problems. I paid for an extended warranty and each time the dealership forced me to pay for repeat issues that repeatedly continued to happen. The battery died more than once right after I purchased it. The car had to be towed a few times because of the electrical battery issue. The fluid that was leaking on the floor caused my leg, lungs and mental health to suffer. I am currently under doctors care for the mechanical issues the car has caused. This is my company vehicle and it has been at Honda of Covington since April 2023. American Honda has refused to help me get to the bottom of why multiple dealerships have refused to fix the vehicle.

Similar problem experienced as the TSB issued for 2015-2016 Honda Fits. Our 2018 exhibits the same issues as the years listed in the TSB below: https://static.nhtsa.gov/odi/tsbs/2022/MC-10208198-0001.pdf Check engine lights and stumbles/misfires deeming the car unsafe to drive. The NHTSA should encourage/mandate the entire 2015-2020 Honda Fit model run to be covered by the TSB above, since the issues/symptoms are identical in model year 2018+ cars as they are in 2015-2016. Eagerly awaiting for oyu to do something about this safety issue. Thank you!

The car will randomly shut off the ACC, collision warning, and lane assist. The dealership says this is due to an error with the fuel injection system and fuel injectors need replaced. There Was a similar recall on the 2015-2916 Honda fit, but was supposedly fixed on later cars. This is still the same flaw but for some reason affects these other safety systems too.

Car is four years old and has 80,000 miles. Fuel injectors became stuck in an open position flooding the engine with fuel and frying the spark plugs. All emergency indicator lights came on and one light (the tire light) was flashing. Honda dealership confirmed fuel injectors were stuck open, but instead of admitting to failure in their parts, they blamed the problem on “bad gas.” An independent auto mechanic confirmed for me that gasoline should not be blamed on faulty fuel injectors. Unfortunately Honda charged me $2300 to replace parts that should last longer than four years.

All the dashboard lights came on in my car. I took it to the dealer and they said they needed to clean the injectors due to carbon buildup. My car has 42,000 miles on it and is 2018 Honda Fit. They charged me 613 dollars to clean the injectors. Then they updated the computer. Two days later all the lights came on again and was throwing a fourth cylinder misfire code 304. They told me they would have to replace the injectors for 2,300 dollars. The Honda only has 42,000 miles on it, and the dealer said he would not be able to cover the cost. I thought injectors were covered under the powertrain warranty, but he said it was covered under the 3 year 36,000 mile warranty. Clearly, from reading other complaints here, there is a major issue with the injectors.

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.

ALL THE WARNING LIGHTS THAT SIGNAL PROBLEMS WITH THE CAR CAME ON INCLUDING THE BRAKE SYSTEM LIGHTS (TIRE PRESSURE, EMISSIONS, CHECK ENGINE, ETC,) DEALER SAID IT WAS DUE TO A FAULTY FUEL INJECTOR DESPITE THIS IS A BRAND NEW CAR WITH NO HISTORY OF ACCIDENTS WHATSOEVER.

FAILURE OF FUEL INJECTORS AT 3 YEARS OLD AND 54K MILES. STARTED CAR IN MORNING AND GOT WARNING LIGHTS, USED OBDII TO FIND OUT THERE WERE MISFIRES, TOOK TO DEALER. WANTS MORE THAN $2000 TO REPAIR.

I BOUGHT MY 2018 HONDA FIT DURING MARCH 2018 AND ON 21ST OCTOBER 2020 WITH 25K MILES ON IT THE CHECK ENGINE LIGHT, STEERING WHEEL, VSA & TIRE PRESSURE LIGHTS CAME ON. IWAS DRIVING AT THE TIME. I YOOK IT TO THE HONDA DEALERSHIP THE VERY NEXT DAY AND THEY DIAGNOSED TO CONCLUDE THAT THE FUEL INJECTORS NEED TO BE REPLACED. THANKFULLY IT WAS STILL UNDER 3 YEAR BUMPER TO BUMPER WARRANTY AND THIS WORK WAS COVERED UNDER THE SAME. HOWEVER THE DEALERSHIP WAS NOT ABLE TO GIVE ME A ROOT CAUSE ON WHY THE INJECTORS NEEDED TO BE REPLACED AND WHAT I NEED TO DO GOING FORWARD TO PREVENT RECURRENCE OF THIS ISSUE. OVERALL THIS HAS SHAKEN MY TRUST IN THE HONDA BRAND AND I NEED SPECIFICS ON THE POSSIBLE REASONS WHY THIS COULD HAPPEN AND WHAT DO I, AS THE CAR OWNER, NEED TO DO IN ORDER TO PREVENT THIS FROM HAPPENING AGAIN. I'VE ALWAYS DONE REGULAR MAINTENENCE PER DEALERSHIP RECOMMENDATIONS & HAVE USED TOP TIER DETERGENT GASOLINE (REGULAR GRADE) FROM COSTCO. SHOULD I SWITCH TO PREMIUM GRADE? I USED TO DRIVE AROUND 300 MILES PER WEEK UNTIL MID MARCH 2020 AND DUE TO PANDEMIC INDUCED WORK FROM HOME I'VE NOT DRIVEN MUCH AT ALL. I ALSO USED NON TOP TIER REGULAR GRADE GAS FROM SAM'S THE LAST COUPLE OF TIMES WHILE THE CAR WAS NOT BEING USED MUCH. COULD THIS BE A REASON?
