2018 Honda Fit

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.

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?

AFTER PARKING AND RETURNING TO VEHICLE, ON START UP, MULTIPLE CHECK ENGINE LIGHTS WENT OFF. CODE WAS READ AS P0303 ENGINE CYLINDER 3 MISFIRE. CAR ~8000 MILES, ON TAKING TO DEALERSHIP WAS TOLD EXTREME CARBON BUILDUP HAD CAUSED MISFIRES. CAR WAS RETURNED, FUNCTIONED FOR A MONTH. ISSUE REOCCURRED, FUEL INJECTORS, FUEL JOINT PIPE SET, AND FUEL PUMP WERE REPLACED. CAR IS CURRENTLY FUNCTIONAL BUT IT IS CONCERNING THAT FUEL INJECTORS HAVE FAILED ON A NEW VEHICLE AFTER UNDER 10,000 MILES.
