Tesla owners have been reporting cracks showing up on their cars. Whether you live in an area where the temperature changes drastically or you play your music loudly or drive on bumpy roads, take a close look at your glasses.
Luckily, That will result in replacement. My glass developed a stress crack like that in the same position about 3 days after delivery.
Wish Tesla would stress test their cars. They really rushed their cars out without adequate QA. Either that or their QA team needs a re-haul.
