Why on Earth would warranty cover a broken windshield? That makes zero sense.
I just looked at a warranty booklet which does specify that glass is not covered (it's hidden alongside convertible top so I didn't notice it at a first glance). I also checked and insurance does tend to cover glass, so I was wrong that it would tend to lean the other way. I just disagree that it makes
zero sense since generally when something breaks on a unit that is under warranty, it is covered.
"Warranty: a written guarantee given to the purchaser of a new appliance, automobile, or other item by the manufacturer or dealer, usually specifying that the manufacturer will make any repairs or replace defective parts free of charge for a stated period of time." -dictionary.com
If a windshield is poorly made then a tiny pebble will obliterate it whereas a normal windshield would be unaffected. Therefore, it is ambiguous whether or not the windshield was defective, thus it is not valid to say it was 100% not a defective unit and therefore not covered. This can be compared to the metalwork being dented in a collision, where it is undeniable that the cause of the damage was another car/object and not simply a defect in the parts. The reason why you are right that glass is definitely not covered is because:
a) warranties seem to specify this directly
b) it's generally known that certain parts of a car that tend to undergo wear and tear will not be covered by warranties.
Since I've never had a warranty before I was slightly hazy on the specifics. I conclude it is undeniably true that glass is not covered upon a close inspection of warranties, but is also undeniably not 100% nonsensical (which is implied by your claim that what I said made 0 sense.
Yes that was fun. I occasionally enjoy being a bad lawyer for practice.
