Hey guys, i have a 2014 IS350 fsport and recently, i realize that my wiper in the intermittent mode get stuck in the middle randomly. I would need to wait 10-15 seconds before it works again or i will have to toggle the wipers to get it unstuck.

It happens intermittently and i cannot always reproduce it, but i manage to capture it on video. Please see the attached video.

Any advice is appreciated. Car is still under warranty.

 

Sounds like a warranty issue.
I think there may be an issue with a relay but the dealer will be able to diagnose and fix it without charge.
Get them to fix it ASAP since it can be a safety issue.

 

I had the same issue. I would end up fighting with the switch while driving to keep the wiper blades from getting stuck. Dealer replaced the wipe relay switch and that solved the issue.

 

Nice video!

What dash cam do you have?

I would email your dealer to schedule a service appointment and attach video so you don't have to explain what is wrong.

 

Definitely a warranty item..

 

I have the same frickin problem! And I live in Seattle so imagine how much it sucks for me lol I'll definitely be taking my car to Lexus soon

 

Same here. My 2014 is250 awd. Was doing the same. Now when I spray the wiper fluid it won't even start wiping automatically. Also when the wipers are in use and I want to turn them off I have to time it just right or they stop in the middle if the windshield.

my car is currently at the dealership to see if I had the rear bumper rust issue or whatever. I'll let you know what they say.

 

Thanks everyone for the responses.

As for my dash cam, i use this-
I wired it up and hid all the wiring from the cam to the fuse box under the driver side.

 

Wiper relay is bad.

 

Update. The dealership asked Lexus if they would fix tee he wiper issue as my vehicle was so close to 50k(54k).

Lexus agreed and fixed the issue with no charge.

Problem was a bad relay in tbe steering wheel.
