Proximity Sensors False Alarms when backing out, no warning when pulling in for front curb

[JC2900106]

My 2015 5.0 has been false alarming when backing out- left rear all the time. Sometimes others. Cross warning backing out has recently stopped working. No warning when getting close to curb front. Emergency stop alert for vehicles ahead is working fine. Help

Make sure the sensors are clean and dry. If they are, it might be a good time to visit your local dealership or car repair shop for diagnosis. However, there may be people here who've gone through the same thing - so let's see if you get any feedback like that...

I've got a similar thing going on - my driver's side front is out & "cures" itself if the temp is below 60 degrees. It's probably bad - rears function fine, however. My cross traffic detection in rear functions normally as well.

That's strange about the temperature. I wonder why that is. Let us know if/when you get it resolved...

I wonder as well.... Must be an expansion / contraction thing of some sort going on. When warmer something expands/moves and loses connection. Pretty weird. It's also consistently repeatable....

Ghost in the Machine, I guess.
