Owner reports
Selected complaints filed with NHTSA by 2015 Honda Fit owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2015 Honda Fit. The contact stated that while driving 45-50 MPH, several unknown warning lights illuminated, with the gear shift indicator light in neutral(N), and the vehicle stalled. The vehicle was towed to an independent mechanic, where it was diagnosed with ignition software failure. The mechanic replaced the ignition switch. Additionally, the contact stated that while driving 35-45 MPH, approximately four to five days later, the warning lights illuminated, the gear shift indicator light was in reverse(R), and the vehicle suddenly stalled in the middle of the roadway. The vehicle was pushed into the driveway of the contact's son. The contact stated that the incident was significantly frightening because the contact was a disabled heart patient, and there were two plates in the contact's neck due to a previous accident. …
The contact owns a 2015 Honda Fit. The contact stated that while driving at an undisclosed speed, the "Check Charging System" warning light illuminated. Additionally, the engine start button intermittently failed to start the vehicle. The vehicle was taken to an independent mechanic and was initially diagnosed with battery failure. However, the failure persisted after the battery was replaced. A diagnostic scan retrieved 6 Diagnostic Trouble Codes stored in the computer. Upon further diagnostic test, the independent mechanic identified Technical Service Bulletin: 20-098 (Warranty Extension: 2015-17 Fit Keyless Start System Error with DTC B12C5). The vehicle could not be repaired under the TSB because the vehicle was outside of the warranty period. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 42,000.
The contact owns a 2015 Honda Fit. The contact stated that the instrument cluster warning lights were illuminated. The vehicle was taken to an independent mechanic who informed the contact about the start system error regarding the engine START/STOP feature. The vehicle was taken to the local dealer where it was diagnosed that the switch assembly needed to be replaced. The vehicle was repaired however, the failure recurred. The contact mentioned receiving a product advisory for the keyless start. The manufacturer was notified of the failure however, no further assistance was provided. The approximate failure mileage was 109,000.
Before I parked, all was fine and the car felt safe, two hours later, I start the car and it has four warning lights on. Now I don't have Hill Start Assist and the car feels like it might 'go out' on me, I think something will keep it from running soon. About two weeks prior, even with keys in the car and with a full battery in both the keys and car, the car doesn't start with the first push of the 'engine start' button (maybe there is a connection here). O'Reilly helped me check the codes, and it states that I should replace the Ignition Coil, as well as the Throttle Body and it is giving the code, P0303: Cylinder 3 Misfire Detected. After some research online, it seems like the Fuel Injectors might need to be replaced as the ones that come with Honda tend to malfunction. Perhaps the TSBs (www.truedelta.com/Honda-Fit-tsbs-99,2015) should be put into consideration. …
My Honda Fit was purchased new in Portland, Oregon. I am the original owner. I began having issues that are documented after moving to Florida, and took the car to Honda in Palm Bay. The issues were grinding noise at the first start of the day, or after sitting for several hours and then restarted. The noise is noticed upon start in am or 1st start and is a grinding noise from the motor area. It sounds like a knock/grinding, like the motor is starting and has no oil in it. But the oil level is okay and it is not out of oil. This continues today, after being at the same dealer several times. The service department stated that they needed me to leave the car overnight to try to diagnose the issue after the car sat all night because the noise only comes after sitting all night or long periods. I left the car more than once at the dealership. …
Many other Honda Fit owners and I have had the same problem of the odometer and fuel gauge not displaying correctly. The soldering pins crack or come loose over time. This leads to failure to tell if you have enough gas in the car. This also leads to failure to show an accurate odometer reading. The odometer and fuel gauge display is digital and the screen often will glitch out and display a jumble of letters and numbers. Sometimes the odometer and fuel gauge display nothing at all. In these cases, you simply have to hope you have enough gas to get to where you need to go. This is a critical safety issue as someone could run out of gas in the middle of fast highway traffic without knowing. This is also an odometer issue because the odometer can sometimes show the wrong number for the total amount of miles driven on the car.
Driving down the highway yesterday at 75 mph. Car said check starter system. Started blinking. All dash lights and system turned off then on then off again. Power steering went off. Car died while going 75 mph. Abs system went down with it too. Had to hard steer and shift down. Parked on side of highway on shoulder. Towed to mechanic who said it's the alternator. Fit has about 125000 miles on it. The start switch was replaced 3 times recall then faulty by Honda dealership. Then the starter needed to be replaced by Honda dealership. Then the battery twice by O'Reilly. Now the alternator by my mechanic. This is not usual for Hondas to have to replace all of those. Seems as though this is a faulty starter system manufacturing. I could've died, had I not been trained by the military on what to do if vehicle lost power.
The digital gauge on the Genuine Honda Fit Instrument Cluster (factory-installed) flickers or goes blank intermittently. It is a well-documented and known defect in this model. The gauge is currently being replaced and I have asked for the defective part for evidence. The gauge includes the odometer, trip computer, digital fuel gauge, and engine oil information. It is a safety issue because you can run out of fuel, cannot track trip mileage (important when navigating in more remote areas), and can't see overall mileage (don't know when to service vehicle, etc.). The dealership has reproduced and identified the problem. No warning messages appeared before failure. The problem first appeared about 3 months ago, but seemed to be an isolated incident. Then one week ago, the problem became persistent.
The vehicle experienced transmission drive issues accompanied by a Check Engine Light. An independent repair facility scanned the vehicle and confirmed diagnostic trouble code P0717 for a transmission speed sensor open circuit. The failure causes unexpected loss of acceleration and erratic power delivery while driving, redlining at 45 mph, malfunctioning of the gear selection display, and creating a safety hazard in active traffic. These symptoms line up with the CVT drive pulley shaft defect addressed in NHTSA Recall 15V574. When I contacted an authorized Honda dealership to address the issue, they stated this specific VIN is not included in the recall campaign. The vehicle and its diagnostic records are available for inspection upon request.
Main display that shows mileage, gas levels, maintenance needs, etc malfunctions - sometimes it goes wonky, sometimes it disappears altogether. It is obviously not safe to not see your maintenance lights or mileage to know when to predict the maintenance. The dealer I take the car to said unless they could replicate the issue, they couldn't do anything. The issue occurs intermittently, often in the middle of a drive, but not currently constant. There are many many other people tho on Honda forums who have this problem also, and theirs is constant, so it's just a matter of time for mine to be constant as well. The issue started earlier this year. There is no error code associated with it so there is no diagnosis for the dealer to give it.
