I have parking assistant monitors on my 2019 NX F Sport and every time, and I do mean every time it rains the warning comes on and says that Parking Assist Unavailable, Clean Parking Assist Sensor. Is anybody else having this issue? When it's dry, works like it's supposed to.

Not when it’s raining. Occasionally in heavy snow. I think you adjust the sensitivity.

Perhaps sensors got wet and short the circuit (not suppose to happen)? Check with service. Mine does it with snow/ice builds up on sensors.

I had this happen one time in my RC during a really heavy rain. Then it never happened again. If it’s a 2019, you should be under warranty so I’d just bring it in if it keeps up.

I traded the car today. Not because of the sensors, but because I was never happy with it. So it's another dealer's problem now.

I had this problem after freeway driving in a severe snowstorm. I had a dealer look for the problem, and he found a very tiny pinhole in the right front sensor. He supposed this could be a rock chip from following another vehicle on sanded roads, and said it would not be covered under warranty. He quoted $650 to replace it, and I declined. I went home and put a very small dab of vaseline on that pinhole (after the car was fully dry). This solved the problem for a week, so then I put a small dab of Chapstick on the pinhole and it has been working now for several weeks. I might eventually get the sensor replaced, but for 5 seconds of chapstick treatment every few weeks, I can live without a $650 repair. I also considered buying the sensor, which can run around $220 for "genuine Lexus" or far less for a knockoff or used sensor on eBay. I have not satisfied myself that I can successfully pull the bumper to replace it myself, but that's a decision for the future.
