Wipers that squeal are usually dried out, they get hard from sitting in the sun.

What a dealer will do is clean the windshield then use Rainx on it, then if the wipers still make noise they replace the blades.

I took a truck I had one day back to the dealer with the same problem, after wasting an hour of my time trying to make them work right, they replaced the blades like I requested.

These new windshields feel rough to the touch they are not smooth like normal glass, after a little use of the blades you can feel the difference, its smoothing the glass as they wipe.

I have 3 kids that sit perfectly fine in back seat. About 5'3" is the tallest. No issues. I sit in front at 6' and have no problems.
