This sounds dangerous enough that I'd reconsider even driving the vehicle. I have a 2019 model 3 and I've experienced phantom braking twice. Both times I was on the highway with autopilot enabled and was passing a truck that cast a shadow over my lane. After the first experience I refused to even use autopilot for months afterwards.

Just recently I was driving in the right lane of a suburban road (with no assisted driving features enabled) and some trees on the curb cast a shadow over my lane and the car absolutely freaked out with collision warnings. Thankfully I was accelerating so it didn't force me to stop, but at this point I'm seriously considering going with another vehicle. Having the car scream at you as you're driving down the road is nerve wracking.

It boggles my mind that people would continue to use a car that randomly breaks without their input.
Most cars have this starting in 2016. Later this year every single car will be mandated to have automatic emergency braking. At least Tesla will have millions of miles of practice. https://www.consumerreports.org/car-safety/most-new-cars-hav...
Most (all?) other cars have radars for this. They do not seem to experience as many problems as Teslas, which is especially telling considering how much more other cars are on the road.
I mean, plenty of people drive dangerously anyway. I'd rather most people brake abruptly than drive 20mph above or below the flow of traffic, weave dangerously, pass on the shoulder, run red lights, fall asleep, drive drunk, etc. If they get in a car that's merely "too cautious", that's a pretty big net win for society.
I have a 2019 and I've used autopilot extensively and i've never had it break when it shouldn't. I've had it beep at me erroneously maybe twice, so I think this is something in the settings that is causing the issue.
I have a 2022 and it phantom brakes all the time. We haven’t touched any settings and if it were a settings issue, I’m sure someone in the Tesla community would have figured it out (there are a lot of Tesla’s out there and yours seems to be the only one that isn’t affected). Moreover, a phantom braking setting would be pretty insane—I have a hard time believing they prioritized a phantom braking feature over, say, more media app integrations.
The "settings" might be about where you're driving. Certain locations might be more prone to make AP see things.
Do yourself a favor and sell that car before it’s worthless. You won’t be doing a favor to the person buying it though.
Lol I can sell my Tesla for $20K more than I paid for it when it was new because Tesla can’t make new cars fast enough. The sky is absolutely not falling any time soon.
