Electrical system

34 reports1 crash
“Passenger airbag weight sensor (light next to radio goes on/off) intermittently not sensing adult passenger in passenger seat. Airbag may not work properly in case of accident and could cause severe injury or death of passenger. Indicator light inconsistently goes on and off. This is an active known recall issue. The VIN for my vehicle is not included in the recall.”

Fuel/propulsion system

30 reports1 crash
“Purchased great condition used 2018 Fit EX on [XXX] from local non-Honda dealership. The next day, on [XXX], the following errors appeared on the dash: tire pressure monitor system, emissions, hill start assist, lane deviation warning, power steering, and vehicle stability assist errors on the screen, and the check engine, tire pressure monitoring system, vehicle stability assist system, and electric power steering lights were also on. Returned to the used dealership that same day. They replaced the spark plugs and battery, still not solved. Took it to local Honda service shop (Performance Kings Honda at 9131 Fields Ertel Rd, Cincinnati, OH 45249), diagnosed as needing fuel injectors replaced (running too rich), and got the fuel injector repair. Got the car back within a week, problem now solved. This is an issue for the NHTSA because it is a known issue on this make and model of car by owners and Honda. See the following: Honda Service Bulletins 21-007, 22-002, 23-042. Fuel injectors are an expensive repair, and they're known to be faulty on these vehicles by the manufacturer. Without correction, other major systems in the vehicle will fail, with issues such…”

Engine

23 reports1 crash
“Car lost power when driving and MIL light came on. Loss of power placed myself and all those around me in a hazardous situation. Took to Honda dealer and P219A engine code came up. They completed the Carbon Buildup cleaning procedure under warranty (Bulletin 21-007). Car still had same issue after cleaning. They adjusted the valves (at my expense) still having the same issue. They updated the FI programming still had the same issue. They replaced the 4 fuel injectors then reassessed. Upon verification they found a single bad injector so replaced injector #4 for the second time. When I searched I found that Honda has reported issues with fuel injectors and it appears the 2018 Honda Fit (Sport) is experiencing the same issue with fuel injectors as other models. I called Honda America, opened a claim (Case # 15771436) regarding the issue and poor troubleshooting and the ultimate issue and they told me to deal with it requiring me to pay for fuel injectors on a car with 88K miles.”

Forward collision avoidance

9 reports
“The lane mitigation and brake system warning lights came on. The car swerved on its own off the road to the right. It put me onto the shoulder of the highway. I had to fight the steering wheel to get the car to move to the left to get back on the road. This happened twice during busy rush hour highway traffic. It also started braking periodically in the weeks leading up to this without any visible signs of being too close to an object or anything else. It was very unnerving.”
