Loud beep then a warning that collision warning had been disabled and the side mirrorsno longer indicated someone was beside me. . First time it's done this and I was on the way to the dealer for service. I mentioned to him and he said it was probably the light rain we had and it had blocked the camera. On the way home it did the same thing and now it was sunny, clear and they had just washed my car. So back to the dealer to have them actually check the sensor.
I was driving on the highway and there was no one around me and the forward collision warning went off. The car then braked on my behalf going 70 mph on the highway. THis has happened twice so far.
