Read an article about EV battery fraud. Some people are changing out good batteries for weak ones, then selling the car to unsuspecting buyers. They take the good batteries and sell for vehicles needing a battery. Twofer
This is no different than someone stealing your wallet or your car. These people should be prosecuted to the full extent of the law (which, unfortunately, doesn't appear to be much these days..).

Even my phone has on board battery diagnostics. Surely an EV will as well? Can those be manipulated to show a good battery when in fact it's weak?
And most people would have a pre-purchase inspection (PPI) done by a dealer or reputable mechanic one should hope. Of course, there are always some really dumb ones out there, ripe for the taking. It's like Darwin in action.
