| Vehicle Speed Control problems |
I was driving my 2019 Model S Tesla on autopilot down the freeway at freeway speed when suddenly it started braking and the alarms went off as if reacting to an impending collision. Only, there was nothing in front of me to react to. The guy behind me rear ended me and spun across traffic lanes. Thankfully, everyone walked away from this with what we think is just whiplash at this time - it could have been so much worse!.
The consumer owns a 2019 Tesla Model S. The consumer stated that whilethey were pulling into the driveway unknown, the vehicle accelerated and crashed into the garage door and wall. The air bags did not deploy, and the steering wheel and brakes seized. There were no injuries. The vehicle was not taken to a dealer or an independent mechanic for diagnostic testing. The manufacturer was not made aware of the failure. The approximate failure mileage was 76. 2.

Repeated unexpected emergency braking incidents, similar to those described in the recent washington post article. The first one happened on the day that I bought the car, and has never improved. One scenario is the same as described in the article - oncoming car/truck on a two-lane road. But it also happens on freeways. If cruise control is on, it's likely that there will be at least one event during a 30 minute or longer session. As others have mentioned, these are often in congested traffic. When a car is following closely, they have to react very quickly. In several cases they have gotten angry because they think I'm slamming on the brakes to discourage them from tailgating. The very first incident, on the day I bought the car, was hair-raising. The car slammed on the brakes in the middle of an interchange where a semi was close behind and there was dense traffic all around both of us. Fortunately the driver was very alert and avoided me without endangering anybody else. But things could have gone the other way. I've mentioned it to local Tesla service people who (at the beginning) said that the car was in the learning period, calibrating the sensors. The user documentation mentions this and suggests that the training interval could be as much as 100 miles. It gets worse and better as Tesla fiddles with the software. It did indeed get quite a bit worse with the release of the full self driving beta -- which I have qualified for but never actually used because. . . Heck, if they can't get cruise control right, I sure don't want them to take on any more responsibilities.
