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 a 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. …
The contact owns a 2018 Honda Fit. The contact stated that at start-up, the fuel and mileage gauge failed to display or displayed unintelligible information preventing the contact from knowing how many miles to empty. No warning light was illuminated. The vehicle was taken to the dealer but was not repaired due to cost. The manufacturer was not made aware of the failure. The failure mileage was approximately 40,000.
The fuel gauge and odometer digital display shorts out. It will either completely go blank or have digital distortion where the characters are unreadable. I do not know how many miles I have left in my gas tank. I can't get a reading for oil life or how many miles I have traveled. I can't even get a reading on the odometer when I take my car in for service. Occasionally the display will return to normal after the vehicle is running for some time. Other times, it never returns. It seemed worse in colder weather, but the summer temps of 90-100, it is still not reliable and it is functions on occasion. I have not taken it in to be serviced because of potential cost, but can see that others have the same problem from my internet searches. My 2018 Fit has about 45,000 miles on it. This has been happening for the past year. …

We have a recurring hazardous issue with our iPhoneX plugged into the USB port on our 2018 Fit EX-L Hondalink radio system. Typically after 20 seconds to hours after starting the car with the iPhone connected, an iTunes song from the phone will start playing spontaneously. And it also almost always occurs soon after using Siri on my iPhone via the Hondalink system. But sometimes it can happen just driving much later for no reason at all. This is hazardous because on occasions when it suddenly played the music the volume was so loud it scared the driver. So this is a safety issue! I found postings about similar issues online that suggested various iPhone settings changes which I tried without success. One posting though simply replaced the Honda radio with a Sony aftermarket radio and that did resolve the issue. …
My fuel gauge display malfunctions whenever the weather is too cold outside, causing the screen to go blank. It remains blank or glitches gibberish words until the screen returns to normal or stays frozen with gibberish language. I've noticed that the fuel gauge display works fine if I'm driving before 8 am during cold mornings, but it starts to malfunction or flicker until the display is frozen or blank once it's past 8 am. This problem has made it difficult for me to know when I'm low on gas as I commute a long distance for work. It's especially difficult during the cold winter months when my fuel gauge display is blank or malfunctioning 95% of the time. I've been experiencing this issue for about 3-4 years now whenever the colder seasons approach. …
The instrument cluster display malfunctioned. The odometer and MPG (fuel economy) display are affected. The component is available for inspection upon request. If the fuel gauge becomes affected by this malfunction, the driver would be unable to monitor fuel levels, risking unexpected engine stalling on highways without warning. The problem has not yet been confirmed by a dealer or service center. The issue is intermittent and currently in early stages. The vehicle was taken to a Honda dealership for a recall repair (NHTSA #23V-858) approximately three week ago, but the instrument cluster issue was not discussed at that time. No warning lamps appeared. The odometer display goes blank for approximately 1 minute after engine start. This began recently and appears temperature-related, improving in hot weather. The MPG display also fluctuates erratically and shows unreliable readings.
