Question to those in the know -- are these roof glass panels attached to the car in a similar way to windshields? I recall that when I had my windshield replaced, they told me that the glue would need a day to bond and not to slam the doors or the glass would just pop off.
I feel like this could be an expected behavior for any extremely new car if that is the case.
The slowest cheapest windshield glue you can get takes like 6hr to cure in normal temps and a couple days at near freezing temps (don't ask how I know this).
These aren't T34s that are driving off the line and to the front. It would certainly have been cured by the time the car made it to the customer. I'm betting their QA process didn't accurately catch and remediate all the cars moved down the line after the glue machine ran dry.
Speaking of windscreens, my chemistry teacher once told us that when he worked at an acid factory they would spew out enough gas to start attacking peoples cars, but to avoid the regulators they would just say "Go and talk to John [redacted]" and they bought everyone a new one no questions asked because it was cheaper than getting shut down.
I feel like this could be an expected behavior for any extremely new car if that is the case.
