has any of you experience lkas fasilure? When we took the car home from the dealership on its first day, it was working. Fast forward 3 months, it is sometimes working, sometimes not. Brought it to the desalership to hasve it looked at and answered that the windsheiled has to be clean all the time for the camera to see, also said it depends on the road markings and it has to be clean and clear to be seen by the camera. I dont really get it because the car has been driven to the same road when we first took it home and everything is working. And I dont get it that you always have to really clean the windshield to make it work. any insights guys? TIA.
