Has anyone with a 2001 LS 430 Ultra had problems with their automatic windshield wipers going on when it's hot and no rain?

 

This is a known issue. Contact your dealer regarding a replacement sensor which will take care of the problem.

 

It may be a known issue, but Lexus will not replace the sensor free of charge. If you have exceeded the warranty period, this is your problem. Its not a RECALL part or replacement campaign. Pony up the cash if you want it replaced.

 

It's even documented in the manual, btw.

 

Well that just sucks..

 

It never hurts to try... You might just show up and talk to a service advisor about the issue. I think Lexus always has room to do little things "on the side". If you ask for this freebie, tell us the outcome.

 

I took my 2001 LS430 to Lexus of Sacramento and they said that the automatic wipers are functioning normally. They referred me to page 29 of the owner's manual where it states that if the temperature on the sensor is over 176 degrees or less than 14 degrees the wipers may go on even though there is no moisture present on the windshield. They said the solution was to remove the wipers from the automatic mode.
