When I picked up my new Limited about a month ago I noticed an odd pattern on the windshield. I figured the detailers missed cleaning it and thought no biggie I'll do it later. It looks like there was some type of residue left from the protective contact paper. It’s odd because it is only noticeable in the morning when there is dew on the windshield, or when the wipers are running.

Well I tried cleaning it later at home and didn’t have much luck. I contacted the dealer and they had me bring it in. I was going to wait until my first service until I drove in the rain for the first time. It was scary. At night it is extremely difficult to see through the windshield with the wipers running.

I brought it in and let the dealer try to polish the glass. It helped a little but its still pretty bad. I want to say whatever it is it appears to be etched in to the windshield. The dealer is going to arrange to have a glass specialist come in and try to polish it out. Has anyone else experienced this?

My RAV had a very similar situation. The problem was that the dealer hadn't prepped the thoroughly - apparently from the assembly point in Ontario the glass has some sort exterior coating which should be removed before the vehicle is delivered to the customer. I used Soft Scrub to remove the coating. Other owners have used other sorts of cleaners. The important bit is to make certain that the cleaner won't scratch the glass but is good enough to remove the coating.

Try using a clay bar with soapy car soap/water as the lubricant. It won't scratch the glass and it just may take off any coating that may be present. Is your rear window the same as the front windshield?

That's a good idea, thanks. The dealer acknowledge that they are going to take care of it but I will definitely recommend this. I have a feeling thats what their glass guy is going to do.

The rear window is fine but the side windows have some of this but not as bad. Thats why I'm confused on whether its residue left from some protective covering or its some kind of spray / contaminant from something else. On the windshield its a very even, consistent pattern. On the side windows its very spotty. For those of us that drive in the snow belt you know how road salt gets on the side windows? Thats the best example I can think of.

The clay bar is a good idea, but first try Invisible Glass. It might save you a lot of time.
It is awesome stuff. I just hate dirty windows.
I agree. That is what I use. I even let it soak for a minute on the glass to try and get it to work but no go.

Just a small update, after several trips to the dealership I'm getting a new windshield today. Wish me luck.

Good resolution. Will the installer be using OEM Toyota glass? In my experience it's more resistant to chipping than are some replacement brands.

Yes they are I told them I will not accept the vehicle with an aftermarket windshield.

Unfortunately I learned shortly after I posted this replacing the window requires a recalibration of the radar/safety system. Supposedly the one certified tech is on vacation until Monday. I guess I'll have to take their word on that one. Anyway I have a service loaner through the weekend. :-(

My windshield is the same way, awful in the rain, I'm going to try to rainex the windshield sometime soon hopefully today time permitted. I hope it will clear up because driving on highways with pouring rain and can't see is scary

Wow. Radar re-calibration over a windshield change? I wonder what happens when the windshield is dirty, bug splatter or fog or rain out? Seems like those conditions would mess with radar more then a simple glass change difference would?

Interesting - replacing an OEM windshield with another OEM windshield requires recalibration of the radar/safety system. Is that because the first windshield was visually compromised?
