The other day, I was driving my car when someone pulled out in front of me, and instead of the precollision warning, the car gave me an error message of some sort telling me the system was unavailable. Now, I managed to avoid the accident on my own, but it still worried me that when I might have needed it, the system didn't work. I took it to the dealer but they couldn't find me any codes, instead giving it back without repair, having told me some BS about the the sensors needing to be clean and unobstructed and weather being a factor. I had told them going in it was a clear day, the car was clean, the sensor was unobstructed, and the warning was triggered when the system should have activated. The service advisor said that even light shining in the camera could trigger that, but I'm not buying it. Anyone have any problem like this?
