My 2017 had them, my 2019 doesn’t. They never went completely away but I suggest glass polish or Rain-X.
Front windshield "hickeys"??
I bought a new 2018 Volt in Sept. Has about 10,700 or so miles on it. Is it just me - or does everyone have 2 hickeys on the front windshield?
These would be from the suction cup grabbers the assembly robot uses when picking and placing the windshield onto the car. Looks like Target store circles.
I thought these marks could be washed off -- but -- I cannot remove them.
Any hints?
I will post pictures if / when I get my car back from the dealer - it has a problem with the DIC - it's in another post.

My 2019 Volt has them as well; although they are mostly viewable only from certain angles. My husband's 2019 Silverado has them, too. Like the OP, I figured they were related to the suction cups used to place the windshield during assembly, but I also have been unable to clean them off.
They're from the rubber suction cups used to hold and transport the windshield to the car on the final assembly line. Since rubber leaves an oil based residue behind use a glass cleaner designed to clean up oil.
In stubborn cases I would try an abrasive glass polish. You can get this from auto glass stores (were I did) and polish with a low speed polisher (beg borrow or steal ). This is meant to polish out shallow marks left by dirty/worn wiper marks (used by collector car crowd on old hard to get windshields). It's a messy job but does wash off. More practically a commercial detailer should be able to handle it.
Thanks all for the replies. Glad to know this is -- um -- normal - and clean-able!
Perhaps 0000 (four) steel wool if all else false.

I would be careful with polishing. With an abrasive such as cerium oxide you can polish out small marks that aren't too deep. If they are deep you need to remove much more glass around them. This causes visible distortions in the glass. You won't like the results. Find a cleaner that can cut the oil mark. I would even try a Magic Eraser. Like most methods, always test is a non important spot first. I have also used a product called Miracle Scrub to remove road film which is basically oil residue.
chocolate or toothpaste is a good light and easy to get polish.
do NOT try Hydrofluoric acid

My 2017 still has them 2 years later after multiple washings and attempts to get rid of them. I can only guess they are actually lightly scratched into the surface of the glass.
The rule of thumb is if you can feel the mark with your finger nail, it's too deep.I would be careful with polishing.
