For the Chevy Bolt they've had a similar software update to reduce the risk of burning your house down, which seems better than the alternative of not having that update.

But they've also been agreeing to buy people's cars back if it's an issue, since selling someone a car with a particular range capacity and then reducing it afterward is obviously problematic.

The Bolt's battery reduction is supposed to be temporary while the final recall fix was worked out. I don't have one so I haven't been following the current news on whether that's been sorted.

In Tesla's case here it sounds worse, because this might be a permanent change where they just said "lol your car is permanently worse now, have fun."
