I've been living with this since that huge Christmas storm blasted KY & OH back on 22-23 Dec. I was idling motionless in the middle of the night with hundreds of other vehicles on an interstate just east of Louisville KY for over 3 hours, in absolute blizzard conditions. Finally wiggled my way out, then backtracked to an exit. Then to a hotel for the night while the storm raged until daylight. Blowing snow & -10F temperatures almost completely covered the car in ice/snow, including most of the front and rear sensors. Ever since then my parking aids have been out. No pop-up proximity display, no audible warnings.
It behaves like that system is turned off, which it isn't. I've turned that system on & off in the settings a half-dozen times now, hoping it would miracle itself back to life. I've cleaned the sensors with a soft cloth... Adaptive Cruise, Emergency Braking and Blind Spot monitoring all function properly. I was going to start checking fuses when I got home, but I happened across this forum this morning & commenced to searching. Didn't see anyone who had the same issue, a couple were close, but didn't offer anything I have not already tried. Other than this issue the Maxima was a champ in the storm.
This is my second Maxima, my Coulis Red 2017 SL was totaled 22 months ago. I've included a couple photos' because it's a gorgeous car! lol.
Has your car been able to spend any time inside a garage or other heated venue, where it might dry out a little bit underneath the front bumper?
Good afternoon and thanks for the reply,
It lives in an unheated two car garage so everything on the body melted away maybe 3 days later? It was absolutely filthy, so I hand washed it in 60 F temps a week ago. I used my leaf blower to dry the car, then on a lower fan speed directly on the fascia side of the sensors themselves. Those are pretty tightly installed in the bumper as you know, so not sure if much air could get in the seams and behind the sensors.
I did see a YT video where the channel owner sprayed WD40 on the seams around his sensors, to force the water out. That seems counterintuitive to me. You're just trading one type of moisture for another, and the latter does not evaporate very quickly. So I have not tried that.

It sounds like you've done all the right things and taking good care of it. Have you tried a battery disconnect and reconnect? Sometimes that gets rid of gremlins.
