CR didn't say the car wasn't good, they said it wasn't reliable. The car performed very well on their tests related to the road; so it is fun to drive, safe, comfortable, etc.
The problem is that it breaks; and then you need to get it fixed. It seems Tesla is pretty good about fixing things without giving you trouble about it; so they make the negative experience into a positive/neutral one.
This leaves you with a good car, not reliable, but still with happy owners; so everything makes sense to me.
And the stock overreacts to all kinds of news, and it is true that reliability will matter as far as their future profits (if they keep everyone happy it costs a bunch; if they don't, they'll lose sales).
