Tesla Will Fix the Model 3's Wonky Brakes with a Firmware Update

A new approach to fixing a car's braking abilities.

After denying it at first, Tesla CEO Elon Musk has admitted flaws in the
Tesla Model 3's emergency braking. Musk has promised a firmware update to
the car in coming days to fix the situation.

The issues with braking in the Model 3 emerged when the magazine Consumer
Reports declined to give the car a full-throated recommendation. "The
Tesla’s stopping distance of 152 feet from 60 mph was far worse than any
contemporary car we’ve tested and about 7 feet longer than the stopping
distance of a Ford F-150 full-sized pickup," the magazine said in its

Stopping distance is a crucial safety factor for any vehicle on the road.
Without a proper understanding of the distance needed to stop once the
brakes are applied, a crash becomes much more likely.

Tesla disputed Consumer Reports' numbers, telling the magazine that their
own measurements showed a stopping distance from 60 to 0 mph was an average
of 133 feet. While that wouldn't put the Model 3 in the top 20 best stopping
distances of all time, it would certainly be a much more respectable number.
The company suggested that Consumer Reports' testing might have been
affected by weather conditions on the road.

Other testers have found the Model 3's braking abilities to be odd. While
Car and Driver declared the Model 3 to be the overall winner in a stopping
distance competition, that magazine noted a "bizarre amount of variation in
our test, which involves six consecutive panic stops—the third of these
stops took an interminable 196 feet."

Musk has now admitted that something is indeed amiss with the Model 3's
braking abilities and vows to fix it.

Fixing braking issues through remote firmware updates is something
relatively new. In 2014, for example, when GM discovered defective parking
brakes in various models, over 220,000 vehicles had to be recalled. When the
Nissan Leaf's electronic brake booster was found to freeze in cold weather,
it too had to be physically recalled.

Of course, there are more Leafs on the road then there are Model 3s. Tesla's
first attempt at a mass-market car, the waiting list for the car has crept
near half a million eager buyers. Named Popular Mechanics' 2018 Car of The
Year, only a fraction of the car's pre-orders have been filled so far as the
company has struggled with what Musk deemed "production hell."

Musk's claim that a firmware update will fix the car within "a few days"
highlights the level of control Tesla maintains in its cars even after they
are purchased. Another such example could be found in Florida last year when
the company was able to remotely expand cars battery power as drivers were
fleeing a hurricane.
