> That was one vehicle.
From the Consumer Reports article[1]:
Because we saw some inconsistency in the braking performance, we got a second Model 3 (a privately owned vehicle that was loaned to CR) to verify our results. CR has tested second samples in previous situations to double-check our findings.
...
CR’s experience with the Model 3’s braking is not unique. Car and Driver, in its published test of a Model 3, said it noticed “a bizarre amount of variation” in its test, including one stop from 70 mph that took “an interminable 196 feet.”
“I’ve been testing cars for 11 years,” Car and Driver Testing Director K.C. Colwell said in an interview with CR, “and in 11 years, no car has stood out with inconsistent braking like this. Some trucks have. . . . It was just weird.”

- sunstone 8y agoWell it looks like brake issue can be solved with a software update [1] in a few days. Which is not too surprising since brakes are a known technology.

- justin66 8y agoIt's because they're a "known technology" that it's rather surprising that Tesla managed to screw up their ABS system in such a dangerous way. If there has been an analogous failure with either traditional Bosch ABS systems or the Toyota systems that integrate with hybrid and electric powertrains - both systems have been around for decades - I'm not aware of it. Not that Toyota hasn't had other sorts of firmware problems...
- sunstone 8y agoTrue, it is surprising that Tesla seems to have a bug in such a known technology. But also because it is such a known technology it would be equally surprising if there wasn't an easy fix for the problem and it turns out there is. A tempest in a tea pot.
- justin66 8y ago> But also because it is such a known technology it would be equally surprising if there wasn't an easy fix for the problem There is no logic to this belief of yours whatsoever. It was an easy fix because it's online-updateable firmware, not because it's "known technology."
