Parking Sensor Random Alerts

[samnt650]

I have Roo Bar / Safari Guard, and OEM winch on the front. My front parking sensor randomly goes off. It appears the two center sensors were causing the problem. Dealer replaced the sensors not solving the issue. Anyone encountered similar problem? How do you have this resolved?

Shutting down the sensor by the button is NOT a fix. Just a work around...

Have you sprayed WD40 onto them?

That may sound strange but senors are notorious for getting water in them and then they stay on or play up. Spraying WD40 on them clears the water out. I had to do that on one of mine a couple of days ago after the heavy rain.

No I have not and they were new sensors (dealer replaced them and didn't solve the false alarm problem

I’m having the same issue with the front sensor. Had it “fixed” at the dealer but the problem is back.

How did the dealer "Fix" the problem? Which sensor(s) causing you the false alarm? Mine were the center two. Dealer replaced them and called it the fix...

Any updates or resolutions? Im 650 miles into my Grenadier and one of the front right parking sensors is giving false alerts. Pretty much every time I come to a stop it will start chiming even though there is nothing in front of the vehicle. I have had to resort to disabling the parking sensors, (along with ADAS and auto start/stop) now every time I drive!

I checked the sensors there is no water, or debris blocking them...

My front right sensor has played up since Oct 2023 (delivery). I turn them off anyway getting into the car but its on the 30K fix up list for the dealer (service by others).

Might be worth getting the dealer to change them. Had mine changed a few months back and completely resolved the issue. Apparently slight corrosion on the contacts on the wiring at the back.

Both of my outer rears stuck on over the weekend. WD40 into both and the issue went away (until the next big puddle or heavy rain).

No issues with mine yet, one tip I have is that you can change the sensor volume to 0 in settings. It remembers your selection....

I have this exact same issue. I turned volume to zero but still hear a faint sound. Do you have any solutions get?

Same here front right is always going off..... I live in AZ so no rain or water yet on it really so dunno but I do have my first service coming up soon so I'll ask them to take a look.

No solutions. Going to bring it up when it goes to the dealer for its 10k mile service probably not until some point next year.

I was hopeful the issue had resolved itself as the sensor didnt glitch on my for a couple hundred miles and then this afternoon on my drive home from work it started beeping again (for no reason when stopped at a light) always the same inner right forward sensor.

Had the same issue (right front sensor). When I took it in for 1st year service, they “adjusted” it. Has been perfect ever since.
Think it had to do with the alignment of the grommet the sensor sits in. Dealer ( Red Noland) had fixed several and seems to have the solution dialed in

I'll have to do the same soon too.

My rear sensor always goes full beep as soon as I put it in reverse, no matter what is behind me. Happens about 50% of the time, no idea what causes it but it’s annoying for sure.

One of my rear sensors goes off occasionally but not enough to annoy me.

Fairly common issue (as issues go). If it cant be fixed with WD40 then get it in for a new sensor.
