   My vehicle activates the emergency braking system while driving. It has happened several times now, almost causing a collision. I took it to the dealership, they held it for a week and gave it back to me telling me they could not find anything wrong with it. They did not fix anything at all. It has since done it once more.

They said they couldn’t get the same reaction I reported, but reset the cruise control. On my way back home on, again on the interstate, and with the cruise control…

   It is not just this vehicle; it is ALL vehicles with adaptive cruise control and automatic emergency braking. When sensors get snow or debris on them, they shut the vehicles down without warning.

Had they not applied their brakes, they would have rear ended me at highway speeds. I also recall that there were no vehicles either in front or to the right ahead of me when it…
