The so-called phantom break problem is well known. But Tesla is transferring responsibility to drivers.
Markus I. has been an enthusiastic Tesla driver for years. A few months ago he bought a new model. But this time he doesn’t really like driving. The reason: The sedan unexpectedly repeatedly brakes in autopilot mode, causing so-called phantom braking. “It’s not a good feeling,” says Markus I. “You know it will happen at some point, but you don’t know when.” The Tesla driver fears these unexpected braking maneuvers will one day lead to a rear-end collision. Especially when the car brakes violently, as it happens over and over again.
The idiosyncratic autopilot with its amazing braking ruined Markus I.’s joy of driving a Tesla.

“Kassensturz” conducts a test drive with Markus I. Activates the autopilot on the highway. It is essentially a cruise control that also automatically maintains distance and lane. Markus I. only intervenes with the pedals when driving. Your hands are on the wheel, as the law says. It happens after a 30-minute drive – the Tesla brakes without the driver having to do anything.
All Tesla models are affected
Markus I’s Tesla is not an isolated case. There are many videos on YouTube that show exactly this problem. The Teslas stop in the middle of the trip, for no apparent reason. Beat Jau from Forum Tesla Switzerland is also familiar with the phenomenon: “Unfortunately, a ghost breakdown is not a ghost, it is an event that occurs on all Tesla models.”
Roland Siegwart is researching autopilots at ETH Zurich. Learn about unwanted braking from other automakers. The robotics professor is not surprised that the problem also occurs with Tesla’s autopilot: “The Tesla has multiple cameras and a radar installed, but no lasers. Only the laser can measure depth information in high resolution. “Siegwart is convinced that this technology is indispensable for safe travel and that it will be used more and more in the coming years.
Tesla holds customers accountable
Is Tesla accelerating too fast on its autopilot? Roland Siegwart suspects exactly that: “Tesla has already come out with the customer, while other manufacturers are still on the road with test pilots. And it must do so before launching this system into road traffic. “
According to Swiss laws and regulations, the driver is always responsible for driving responsibly, even when using driver assistants.
“Kassensturz” confronts Tesla with these accusations. The company only responds in writing and holds the customer responsible: “According to Swiss laws and regulations, the driver is always responsible for driving responsibly, even when driving assistants are used. Active cruise control can be easily interrupted and overridden, for example using the pedals or the steering wheel. “
For Tesla owner Markus I., a joke: “If the car stops by itself, from 123 to 80 in 1.1 seconds, nobody can react, you are at the mercy.” This phantom braking is too dangerous for him, he wants to return his car. But that’s not so easy: Tesla was hard to reach. They discouraged him over the phone and the company did not respond to certified letters. Therefore, Markus I. has hired a lawyer in the meantime.
