I have a persistant issue with the parking sensors on my MY2018 Lexus NX where by an alarm comes up on the dash stating "Parking Assist Unavailable Clean Parking Sensors" no matter how much cleaning is done the alarm will not clear but will clear spontaniously after a period time, these are smart sensors. the issue has been occuring for over a year

Lexus have made 4 attempts to resolve the issue, resucuring the front number plate and making adjustments to the software, Lexus Cardiff have stated that they have seen the issue on other cars and applied a repair that they had used before but with no resolution. Lexus GB have said that they have identified a software issue with the parking sensor ECU and reflashed the ECU again with no resolution.

The appearance of the alarm cannot be predicted and it will stay up, disabling the parking sensors between 15 minutes and several days, it does however appear to be more common in damp weather and continues for a few day after being driven in the wet even if there is no further rain. Has anyone else had a similar experiance?

I have & it's driving me nuts! It is also dangerous as you are unable to see the map (sat nav) when driving. Also flashing orange lights do nothing to help your concentration when driving at night. 

I have had problems with the Parking Assist In unavailable appearing on a regular basis mainly when it is wet weather. It is driving me nuts!!! I am taking the car back to the Tunbridge Wells dealership for the third time. It is dangerous when driving particularly at night. You are unable to see the Sat nav map if this problem occurs on the dash. I hope we can resolve as I think the car is fantastic & I'm a big fan of Lexus & the after care. They have been very understanding & helpful but the issue is  frustrating nonetheless.
