I am unsure of when it first occurred, but before it finally stopped notifying me of a possible front end collision, I had noticed that it would begin to randomly notify me of a collision warning from the front end when there was nothing in front of me or near me. Then one day it just stopped notifying me all together. I checked all fuses and they are all working properly. That I can remember, it has now been more than 4 months now. Once it completely stopped, everytime I start my car, I get a notification on my dashboard stating collision forward collisiin warning not working.
