2018 Honda Fit Problems

What owners report

Owners of the 2018 Honda Fit most often report fuel injector trouble that starts as a misfire or rough idle, sets warning lights, and is sometimes linked by dealers to carbon buildup on the intake valves. A separate and very common theme is the right-side instrument cluster display (fuel gauge, odometer, mileage readouts) going blank or showing scrambled characters, usually in cold weather. Paint peeling and water leaks into the footwells also come up repeatedly.

   Fuel injector failure / misfire with carbon buildup

   • 29 complaints (25%)
   • median 35,737 mi at 3.5 yrs old (8 state mileage, few)
   • owner-quoted repair $1,475 (median of 6 quotes)
   • filed 2019–2026

   Owners describe the check engine light or a cluster of warning lights coming on, often with rough idling, hesitation, shaking, or a misfire code (P0300-P0304). Several say the dealer diagnosed carbon buildup on the intake valves or failed fuel injectors, first cleaning the injectors and updating software, then recommending injector replacement at roughly $2,000-$2,600. Some report the symptom returning after repair, and a few were told the problem was due to bad fuel. Reported from as little as a few thousand miles up to around 115,000, with many cases between about 20,000 and 65,000 miles.

   6 related service bulletins

   What to check: Ask whether the intake-valve carbon cleaning and PGM-FI software update described in Honda's service bulletins were performed, and request any injector replacement records. On a test drive, watch for rough idle, hesitation, and a stored or pending misfire code.

   “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. …”

   NHTSA complaint #11366294, filed 2020-10, 25,043 miles

   “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. …”

   Instrument cluster display blank or scrambled

   • 17 complaints (15%)
   • median 31,425 mi at 2.8 yrs old (4 state mileage, few)
   • filed 2020–2026

   The right-hand gauge display that shows fuel level, odometer, and mileage sometimes blanks out or shows unreadable characters, so owners cannot tell how much fuel remains or how far they have driven. Many say it happens on cold starts or in cold weather and sometimes returns once the car warms up, and some report it eventually stays blank. Dealers have confirmed the faulty cluster and quoted roughly $500-$1,200 or more to repair or replace it, with some owners reporting no repair. Appears from very low mileage (under 2,000 miles) through 40,000 miles and beyond, most often in cold weather or on cold starts.

   What to check: Start the car cold and watch the fuel/odometer display for blanking or scrambled characters, and ask whether the cluster has been replaced or repaired. Note the fuel level before driving so a dead display does not leave you guessing.

   “2018 Honda FIT lx, 1,700 miles. After about a 10 mile urban drive in around 40f weather, I stopped at a light and the odometer/gas display flickered and the numbers were scrambled. It glitched one more time, and then disappeared after about a minute. This is a common safety issue for 2015+ and should be recalled. As far as my research I did not find another case of this happening with such low mileage, only that it is more likely to happen in cold weather. …”

   NHTSA complaint #11310525, filed 2020-02, 1,750 miles

   “Last week the mileage/gas screen on my Honda FIT glitched a couple of time while I was driving down the road. It then went back to normal. A couple of days later I went out to start the car and the screen was blank. After about 10 seconds the screen came on an performed normally for the rest of the day. Today, I went out to start the car and the screen was blank, a few seconds later the screen displayed what looked like every light it could and the screen had all kinds of gibberish on it. …”

   Fuel pump recall parts unavailable / stalling and hesitation

   • 13 complaints (11%)
   • median 60,000 mi at 6.5 yrs old (3 state mileage, few)
   • 4 mention a crash, fire or injury
   • filed 2023–2025

   Owners describe hesitation, poor acceleration, stalling, rough running, or a fuel odor, and several connect this to the fuel pump recall covering this model year. Many complaints concern the recall itself: notification arrived, but dealers said the replacement part was not yet available, and some owners waited months. A few report that the recall work or related diagnosis did not resolve their symptoms. Reported across a wide mileage range, from around 12,000 to about 113,000 miles, and frequently in complaints filed while the recall remedy was pending.

   Recall 23V858000

   What to check: Ask whether recall 23V858000 (fuel pump) has been completed and get documentation, since parts availability has delayed repairs. During a test drive, listen for hesitation or stumble under acceleration and note any fuel smell.

   “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.”

   NHTSA complaint #11575871, filed 2024-03

   “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. …”

Buying note. Have a pre-purchase inspection focus on the fuel system and instrument cluster: pull stored codes, confirm whether the carbon-cleaning and software bulletins were applied, and test the gauge display on a cold start. Also confirm in writing whether recall 23V858000 has been completed, and check carpets and paint for water damage and peeling.
