Anyone have their pre collision alert go off when no one is in front of you or back of you or behind you?I had this happen today entering the freeway from a on ramp.It only happened the one time today and everything seems fine.

 

Likely the sun reflecting off something like a sign.

 

I deactivated mine, it went off over a guy in the bike lane it activated the brakes, then there was the whole blocking roads events last year.

 

Yes, I adjusted the sensitivity down.. 600mmph, and approached a steep hill. Startled the snot out of me, didn't know what happened at first.

 

About to deactivate mine!! Mine also goes off for no obvious reason, I think it is more distracting than just paying attention to the road and watching the vehicles around you…just my $.02.

 

I keep it turned off.

 

Its annoying but it works very well When it needs to. Its stopped me from hitting a girl who stopped at a green light. But I have had it slam the brakes due to a tree shadow on the road, almost got me rear ended. randomly when you go to pass it will alert you as well.

 

I have found that if it detects you coming up on an obsticle too fast with no foot on the brake, it will activate regardless if you actually stop fast or not.

 

I have this turned on on my 19 platinum and have yet to have it alert or stop the truck. I was on the highway and some slowing down so I let my truck get close and saw the red on the dash where the adaptive cruise control is but no alert or stopping. And the other vehicle I've had with this feature without giving me tons alerts by this time

 

Driving 600m mph is simply irresponsible.
