My new 2008 LS600 has interesting quirk. Sometimes at start up the windshield wiper engages for one cycle. The car is garaged so no condensation on the windshield. Is my car trying to tell me something?

 

I doubt it, my car does this also when it's completely dry. Just one wipe and it's done.

 

Does it do this every time?

 

Mine does not do it every time but often enough.

 

 

Mine will wipe when there isnt anything on the windshield once in a blue moon, but its not common at all.

 

Like the OP mine just does it at start up sometimes and not again during the drive.

 

Since nobody has mentioned it yet, do you all have the wipers in AUTO position when this happens?
I always turn it off when I park the car, since I still remember the time a bird had pooped on glass, and upon startup my car happily smeared it all over the windshield.

 

Yes it stays in the AUTO position.

 

Thanks, but wipers are not in auto. Its just weird. Can it be temp related?

 

If the wipers aren’t in auto, then something is wrong. Could be a low battery.

 

Great Point. I replaced my 12V about a month ago and haven't noticed it since.
