i recently started getting a "collision sensor blocked warning" took it to the dealer and of coarse they said nothing was wrong. The problem has not gone away and seems to happen in the same spot on the tollway. Not sure if there is something about the toll tag sensors that set it off or what. get a similar message when using adaptive cruise also. Anyone else had this problem?

 

Whats the manual state?

 

check to see if it's blocked by debris, which it is not

 

Sounds like the toll tag interrogator interferes with the radar. Especially if the toys are operational once you clear the area.

 

I have a '19 Lariat with Pre-Collision and AEB. It hasn't been working since the day I got the truck. Been to the dealer who couldn't have been more helpful, but still didn't sort it.




Today I removed my 407 toll transponder and guess what?




Pre-collision and AEB both working perfectly.
