NHTSA Looking Into Tesla Vehicles Over 'Phantom Braking'
The National Highway Traffic Safety Administration (NHTSA) has announced it is investigating 416,000 Tesla vehicles after receiving 354 individual complaints of unexpected braking.
America’s largest purveyor of all-electric vehicles was forced to cancel its push of version 10.3 of its Full Self-Driving (FSD) beta software last fall after receiving reports that it was creating problems for some users. Drivers were complaining that the update had created instances of phantom braking after the vehicle issued false collision warnings. However, things only seemed to get worse as complaints to the NHTSA grew more frequent after bumping FSD back to an earlier version.
It’s not clear if the deluge of reports that occurred between November and today were the result of Tesla mucking up the software fix or if attention from the media simply encouraged people to file more complaints with the agency.
I’ll be the first person to say that FSD (and most other advanced driving aids) are kind of a scam. Tesla may be the worst offender due to its legitimately irresponsible marketing language, especially the part about “Full Self Driving.” But I’ve been in Chevrolet Equinoxes where the car suddenly decides it needs to stomp on the brakes to avoid colliding with an obstacle that’s still 40 yards ahead. Vehicles manufactured by other brands have offered similar difficulties, especially when inclement weather some into play. So, whatever your thoughts and feelings happen to be about advanced driving aids, the bar for excellence remains low.
The NHTSA also seems to have developed a fixation with Tesla which leaves me kind of torn. On the one hand, I feel like the regulator favors legacy manufacturers with longer — let’s say — working relationships with relevant government personalities. Over the last few months, the automaker has been subjected to recalls and investigations pertaining to faulty defrosters, bad trunk latches, custom horn tones, rolling stops, and smacking into parked emergency vehicles. But Tesla is also beta testing on customers that paid extra for a feature that has habitually failed to live up to its name and just keeps getting more expensive — making sympathetic feelings harder to drum up.
Documentation shows that the NHTSA will be examining 2021-2022 MY Tesla Model 3 and Model Y vehicles. The agency summarized the complaints by saying issues typically take place while drivers are utilizing advanced driving aids, including adaptive cruise control, when the vehicle “unexpectedly applies its brakes while driving at highway speeds.”
“Complainants report that the rapid deceleration can occur without warning, at random, and often repeatedly in a single drive cycle,” the agency explained.
While this is not a recall, the preliminary investigation is the first step the NHTSA takes before issuing one. This usually hinges on the number of reports, whether or not the regulator can replicate the issue, and the level of risk it presents. For now, there don’t appear to be any injuries or even crashes associated with the apparent defect.
There’s been a lot of speculation as to what’s causing phantom braking. But the most popular theory is linked to the company’s decision to remove radar from newer models. While presumably a cost-cutting measure, Tesla CEO Elon Musk insisted that its vehicles could perform just as well without them by leaning on the exterior camera array.

- Sgeffe Why on Earth can’t you just get the torque specs and do it yourself if you’re so-inclined?!
- Sgeffe As was stated in another comment, the FAA nominee went down in flames. But the NTSB chairwoman certainly didn’t, and she’s certainly not qualified either!Lots of this kind of stuff going on both sides of the aisle—Ben Carson would have arguably made a better Surgeon General than HUD Secretary under Trump, for example.
- Art Vandelay Interesting, the Polestar 2 I had as a rental utilized Android Automotive which is what GM said it is going to exclusively, yet it still offers Apple CarPlay according to this. Wonder if GM will do the same.
- Stuart de Baker EVs just aren't ready for prime time for those with a single car and who take road trips. Being able to charge as soon as you arrive at a charging station, and even the chargers working on your car is a crapshoot. In the former case, you could have to wait for nearly an hour while someone else is charging.I also don't find EVs particularly fun to drive (I've driven a Tesla Model S and an Ionic 5.) I LOVE driving my '08 Civic (stick). I love the handling, the feel and responsiveness of the engine, the precise steering (the Michelin Pilot Ultra Sport tires help, but even with the snows on, the car is a joy). I have 152k on the clock, and hopefully another 25 years or so of driving (I was born early in the Eisenhower Administration and I have exceptionally healthy habits), and I'm going to try to keep the Civic for the duration.My Civic causes a less global warming emissions than some of these humongous battery operated trucks.
- FreedMike They should throw in a Lordstown pickup with every purchase. Make it the “vapor twofer.”

I wonder why Tesla is being singled out here? My wife's Acura occasionally behaves oddly when in ACC mode, presumably because the Mobileye cameras detect a threat or pattern that makes it hesitate. A bit irritating. NHTSA has declared war on Tesla for political reasons, this will show up as another issue two months from now.
