The common sense in the back of the argument is sound. However the numbers aren’t but proving it true, in step with Shopper Studies.

CR comes via its information another way than maximum reliability research.

The mag doesn’t take a look at each automobile available on the market.

A lot of these new options can continuously imply new issues.”

Some Extra Dependable Than Others

Kia EV6 house owners reported fewer issues than house owners of some other EV, CR says. The Tesla Fashion 3 got here in 2d, regardless that the mag is cautious to notice that it didn’t fee the reliability of Tesla’s motive force help methods. The Nissan Leaf took the bronze spot at the podium.
