Adaptive Cruise Control problems of the 2018 Honda FIT

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.

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.

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.
