Data refreshed
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems. Every record below is an owner-reported complaint about the 2018 Honda Fit submitted to NHTSA — not a confirmed defect, not a recall and not a manufacturer bulletin. 12 reports on file name it.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Failure of the, Multipurpose Camera (Honda Sensing), causing adaptive cruise control, collision mitigation, and lane-keep assist to stop working. Failed in 2023 and was replaced by honda costing me 1,600 dollars. Now, 3 years later the camara failed again and it will be another 1,700 to replace.
Multipurpose camera stopped working in normal conditions. Dealership says the camera is faulty. Several safety functions such as lane keep assist, collision mitigation, adaptive cruise control no longer work.
Component/System Involved: The multi-purpose camera system on my 2018 Honda Fit has malfunctioned, disabling critical safety features such as Adaptive Cruise Control (ACC), Lane Keep Assist System (LKAS), and Collision Braking Warning System (CBWS). Safety Risk: The failure of these systems creates significant safety risks. Without ACC, the vehicle cannot maintain a safe distance from other vehicles. The LKAS no longer provides steering assistance to help stay in the lane, and the CBWS cannot detect or warn of potential collisions. These malfunctions increase the likelihood of accidents, especially during highway driving or in heavy traffic. Problem Reproduction and Confirmation: The issue has been reproduced and confirmed by Norm Reeves Honda Cerritos during an inspection on 8/13/25. Inspection Details: The vehicle has been inspected by a dealer/service center, which diagnosed the problem. However, the manufacturer has not offered a resolution, nor has the vehicle been inspected by police, insurance representatives, or other parties. Warning Indicators: Before the failure, warning messages appeared on the dashboard, including alerts for ACC, LKAS, and CBWS system malfunctions. These warnings initially appeared on 8/12/25 and became more frequent over time. I believe this issue may be a design or manufacturing defect affecting other vehicles of the same make and model. I urge the NHTSA to investigate this matter to determine if it represents a broader safety concern.
Multiple systems failure simultaneously. Lane Keep assist system, adaptive cruise control, braking system failure and automatic emergency braking as well as forward collision warning. This appears to be due to some fault within the system that multiple owners experience — many mentions of this issue in online forums. When taken to Honda they cannot even determine why but just start suggesting replacement of various systems to include the camera/radar but cannot guarantee this will fix. This is a safety issue and happens through no fault of the vehicle owner it just pops on one day and remains intermittent.
The contact owns a 2018 Honda Fit. The contact received notification of NHTSA Campaign Number: 23V858000 (Fuel System, Gasoline) however, the part to do the recall repair was not yet available. The dealer was made aware of the issue and confirmed that parts were not yet available. The contact stated that since receiving the recall notification, on four occasions the vehicle independently accelerated while idling, without warning. The contact had the vehicle towed to the dealer for an inspection; however, the dealer could not duplicate the failure. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue and confirmed that parts were not yet available. The failure mileage was approximately 12,800. Parts distribution disconnect.
I have had my Honda fit for almost 7 years now and every winter I have an issue with the ADAS system. The car will throw a warning saying the sensor is obstructed and to clean off the windshield. Every time I check to make sure there's nothing obstructing the sensors. If I had to guess, the plastic covering is trapping heat from warming up the car and fogging the glass but I can't do anything about it since the plastic is not removable. It seems like a flaw in the design that operating the car with the heat on in winter can cause issues with the ADAS.
The contact owns a 2018 Honda Fit. The contact stated that upon starting the vehicle, the infotainment screen failed to illuminate. The contact stated that the failure occurred intermittently. The vehicle was taken to the dealer, where the failure could not be duplicated; however, the failure recurred. The vehicle was taken to the dealer to be repaired under NHTSA Campaign Number: 23V046000 (Back Over Prevention) however, the failure persisted. The vehicle was not diagnosed nor repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 89,075.
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.
all vehicle warning lights came on specifically the check engine light for an emissions system problem. At the time the car had around 100,000 miles so it was suspected that the issue had to be with the battery, o2 sensors, or spark plug and ignition coil, so those parts were replaced. The vehicle still shows all the warning lights and reads codes for misfires in the first and second cylinder. If the issue with the fuel injectors was recalled and fixed for the 2015-2016 model Honda Fit, then it cant possibly be that the 2017-2020 honda fits also have a fuel injector problem, unless they also do and the issue has been neglected.
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.
The automated braking system deployed at maximum braking without warning 3 times in 60 miles of highway driving (this was the first time I had driven this car on a highway). The road in front was completely clear of both cars and debris for several miles, it was sunny without glare, and the road was dry. The one common factor was that all 3 times occurred while passing a semi truck, as I pulled level with the cab. I was thrown forward against the seatbelt while the car slammed on its brakes while beeping and flashing the orange 'BRAKE' warning, dropping from highway speeds by about 25 mph before I was able to intervene. Thankfully there was also no traffic behind me, so I was able to recover control of the vehicle, but otherwise this would have absolutely caused a collision. Prior to this incident, there were no warning signs or indications of a problem. I had purchased the vehicle as a Certified Pre-Owned vehicle less than a week before, at which point it had been thoroughly inspected by the dealership and certified as free from issues. I have reported the issue to the dealership, but from cursory searching online it appears this is a known, unremediated issue - a quote from Wilde East Towne Honda (not my dealer): "You may find that CMBS is giving you notifications and even feedback when no threat is detected. That is normal on occasions...CMBS picks up 'optical illusions' occasionally"
REGULARLY WHEN SHIFTING INTO DRIVE FROM PARK OR SHIFTING INTO DRIVE FROM REVERSE, THE CAR WILL FAIL TO ACCELERATE AT ALL FOR SEVERAL SECOND DESPITE GAS PEDAL ACTUATION AT FULL, OR PEDAL ON THE FLOOR. UNPREDICTABLE ACCELERATION WHEN SHIFTING INTO DRIVE DISALLOWS DRIVER FROM DRIVING CAUTIOUSLY AS THE UNKNOWN VARIABLE IS DISTRACTING AND DANGEROUS IF IN A SITUATION WHERE THE CAR NEEDS TO MOVE ON COMMAND. VEHICLE WAS STATIONARY.
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
