Parking Sensors Problem

[Wholeo]

Just had the ECM replaced under recall on Monday so I'm not sure if this part of the issue. While driving today (Wednesday) the front parking sensor started chirping and dash was throwing out warnings that I was about to hit something that wasn't there. Then the sensor would shut itself on and off displaying WIPE, there was nothing to wipe other then a fine mist that froze on the sensors. At one point a message popped up saying front sensors and auto wipers not available so I took it to the dealer and no codes were triggered. I don't have collision avoidance so I'm wondering why the truck moving at 30 mph would activate the parking sensors?Any info would be appreciated, I hope I don't have to deal with this on my truck with 1200 miles on it.
And of course couldn't duplicate problem with the service writer.

I'm surprised this is the first time you've had to deal with it. I've dealt with that on the last 6 vehicles I've owned that had parking sensors (4 of which were/are Ram or Dodge). Any time there is enough snow or ice or mud or anything that even slightly coats the sensors I know it is time for me to turn them off so I can avoid the false alarms.

Just dropped my 21 BH off at the dealer for the tailgate recall, battery check and also to look at the front park sense. Mine will go off with a spotless truck, nothing on the sensors. It always seems to be the passenger front and has intermittently since new.

First vehicle with the sensors, sounds like a pain in the azz. Truck won't let me shut them off, they go on/off on their own with a prompt to wipe. Just trying to figure out why a parking sensor would be blaring and flashing at me when I'm traveling at speeds that would not indicate I was trying to park. The info about the sensors being so sensitive is good information to know. If the problem persists maybe I will see if the dealer can disable them totally.

You have button to turn them off under the radio…

I know I have a toggle switch under the radio. I turned it off and the parking sense has a mind of its own and comes back on, don't know how to describe it other then this parking sense crap has a mind of its own in my truck. As LateToTheParty & whitexc stated it don't take much to set them off and the 15 minutes the truck sat in the dealers heated bay before they scanned it melted the nano layer of frozen mist on the sensors which puts the puzzle pieces together for me now. Thanks guys! The big question now is why warnings for a parking sensor goes off at 20/30 mph?

To follow up on this…dealer found nothing wrong with my park sense. Front passenger side alarms constantly even on a clean dry truck. I don’t have time to play the dealer game so I turn it off when it sqawks at me.

Another techie BS feature that is unnecessary and problematic.

Unless you like not hitting objects that you can’t see, or perhaps need to park as close as possible to a wall?

Go back to your Model T.

I don't have the front sensors and i have no issues with either of those tasks…. Lol

Let's not let this thread go sideways please.

I had to have the the trucks ECM flashed again after the initial recall replacement flash. Truck starting throwing codes, even had the dreaded 150 to 5 DEF stored message that would not go away after the dealer could not find any issues. They did the reflash to erase the DEF stored message and the parking sensors are not acting up anymore so maybe the first flash was corrupt.

That’s constructive, we should just produce model t’s. Society did fine without a backup camera but definitely more convenient since you can SEE with your eyes. Don’t need a beeper that’s not even that accurate in addition- waste of money and tech. Now a front camera would be better since these sensors are absolutely stupid but hey- you look forward so you don’t need either unless your (stupid or lazy) - you fill in the blank.
