I keep hearing how "Tesla paint is soft" but nobody ever has any evidence to demonstrate why. I think this is one of those things that just gets said enough that people assume it to be true. I also think some of the PPF vendors continue such dialog, for obvious reasons. That aside, I drove my wife's BMW X5 off the lot a few years ago and before I got home a rock kicked up, cracked the windshield and chipped the paint. It absolutely sucked. I was pissed. Not even 2 miles in and I had a cracked windshield AND needed paint repair.
My point is, s*** happens. I think the stone chips on the front of a Tesla are more a product of the grill-less design than a paint defect. I feel your pain with the paint chip, but I'd be stunned if Tesla did anything beyond offer a free touch up paint bottle. Hopefully I'm wrong!
