Parking Sensors Sound While Driving!

[SteveAvery]

My Lexus SC430 parking sensor alarm sounds intermittently while I am driving. (No, I do not tailgate the car in front.)

It has happened several times, all but once when it was raining. On that one occasion, the sun was shining. It happened again today while it was raining, and continued to sound after the rain had stopped, but the road was still wet.

What could be causing this to happen, and how can it be prevented, please?

I have decided to fit an ON-OFF switch, if the problem cannot be solved conventionally.

I had same problem sounded like a machine gun. What i did when it occured again, i got out and tapped the front ones and it stopped.

It has only occured once since, and as you say in the rain. I am going to spray mine with electrical cleaner not wd.

Aha! It seems that wetness may have a bearing on this problem, then.

I also shall try electrical cleaner.

Please tell us if it recurs after the spray.

Yes took ages to sort the noise source, not had a problem for a couple of weeks now. Famous last words but i am still going to treat them all the same.
