What's your point? I've had a gazillion windshield replacements over 50+ years and had only one that was a problem ... and that was in the 1970's.

My 2014 Sienna, purchased new, is on its 3rd windshield and all of them have been fine until the previous two were cracked by rocks..

 

SORRY, LONG WINDED POST

All cars in the USA the VIN number must be visible through a window in the left front bottom, since the windshield has a baked on black area on the bottom so it hides the glue and body parts. By NHTSA windshield manufacturer has to provide a window to be able to show the VIN through the window. during manufacturing assembly apparently there is a computer that mounts the windshield where it deems what the right place. Apparently my Sienna windshield was mounted too low. that was determined by measuring the gap where the windshield ends on top and the distance to the body.
I've been to Automotive Assembly Plants mostly GM and I know the procedure to mount the windshield in the assembly line. Only time human hands touch it to make sure the the windshield is mounted correctly and they have about 1/8 of an inch to nudge the windshield in position. As the car rolls down the assembly line every step that requires a particular position like the door gaps, trunk gaps, etc So the assembly worker has a set of plastic gauges to measure the distances. Toyota Corollas had a big problem with that about 3 years ago, where you can see by eye the gaps in trunk where not equal between the left and the right.
It's a manufacturing defect. The workers are not checking the gaps at mounting at the end of the assembly.
The robot can and must be programed to put it on the right place. it has laser points that read the edges of the body and that gives them the position to mount the part.

The VIN is on your title and your registration. Guess I am confused by your post.

 

About the only way to locate the glass perfectly is to build a jig, while dry fitting, then give the urethane a couple hours to firm up before removing the jig and installing trim. That's what I did when replacing my own but most people don't want to wait. Professionally installed glass is usually close enough, as long as it doesn't leak or touch metal. I only did it to save money.

 

So back to fundamentals: I think the OP's issue is that he would like to have the VIN on the vehicle clearly visible for the purpose of future vehicle sale/transfer, insurance company physical inspections, etc. And I'm sure he'd like to know why his is not. Just a bad factory original build, or is there something more sinister afloat on his used car purchase?

To fix it likely requires removal of the upper dash pad, or removal of the windshield. Bonded windshields might not come free without breakage, and that opens up a whole new can of worms.... So, what to do?

 

Thank you for this post! I’m at a CA DMV trying to register my vehicle from out of state and get CA plates and the vehicle inspection officer is making a big deal out of not being able to read my VIN through the windshield - you can only see the bottom half!
