Consumer Reports magazine does not recommend Tesla's Model 3, saying the mass-market electric car has big flaws in its braking system. But the magazine's director of automotive testing told Cheddar he would re-evaluate the car after Tesla makes upgrades.

In the magazine's test, it took a Model 3 going 60 miles an hour 152 feet to stop ー 20 feet longer than other cars in its class. "That's not going to help you prevent a crash if you really need to slam on the brakes," said Consumer Reports' director of automotive testing Jake Fisher. "We were very surprised when we saw the distance out of the Model 3."

Fisher said he personally spoke to Tesla's CEO, Elon Musk, on Tuesday night. Musk told him Tesla was looking to put out a fix as soon as the weekend.

Tesla has the ability to re-calibrate its braking system through its software and send updates to cars already on the road.

"If we get the update on our car we are absolutely going to retest that vehicle," said Fisher. "If it really shortens those distances this car very well can be recommended after we do that."

When asked how often Consumer Reports changes its recommendation, Fisher said the magazine is regularly testing and re-testing cars.
