A period of automotiv electronics, they tried to do cheaper than the cheapest without taking acount of thoses stresses. Bad things happens, and now the automotive certification is a way for part manufacturers to sell to a higher price. That doesn't mean all stuff that aren't automotive aren't reliable ...
Actually that's not true, automotive qualification does require both ASIL qualification and validation of passing thermal stress tests. It's not just rebranded hardware.

In either case, it doesn't matter. If you part isn't automotive qualified it won't go into any vehicle made by a large OEM. I can't speak for Tesla (who doesn't seem to even know what a FMEA is), but the liability of not using automotive qualified parts is too high. Whenever there's a standard established, not adhering to it drives up the cost of lawsuits significantly.
