2018 HONDA FIT Forward Collision Avoidance Warnings Problems

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.

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 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.
