Sometimes, yes you see the speed limit sign on the display change briefly. Car obv shouldn't do this anyway as it's not seeing a road sign. Logic also dictates that if you're on a freeway driving at speed in a straight line, then it's 100% certain that you didn't just turn onto a cross road with a speed limit 40% lower.
I've driven on roads where it crosses through a town and the speed limit is dropped from 55 down to 35 in that section (then gots back up). There are also situations like highway dead ends where it exits at the end immediately to a local road. So I don't think a sanity check code that excludes that necessarily is valid.
Service confirmed it’s a sw bug and told me to report it using in-car voice report (which I’ve done many times).I finally caught a phantom braking event on camera. Note how the Max speed setting changes all on it's own...
It drops to 60 without me doing anything and the car brakes pretty sharply. Then goes back up to 65
Sorry to hear about your issue man. As someone who experienced the same problem over a dozen times (minus the car shutting down part) I understand at least some of what you've been through. It's extremely dangerous and scary when it happens.
I don't think it was phantom braking so much as an issue with the car. The cameras on your car probably would not have been calibrated yet, so you wouldn't have been able to use TACC or EAP. You don't say whether you were using it or not, so I am assuming you were not.
What you describe is not phantom braking, you simply have a defective car. If it auto braked and you weren't in AP, that might have been the AEB system. But even that system does not disable the vehicle, so obviously something else is wrong with your vehicle.
Um no. "Phantom Braking" as talked about all over TMC refers to Autopilot rapidly slowing the car down because of a variety of reasons. I have never seen it referred to what appears to be the emergency braking system bringing the car to a complete stop in the middle of the road with the car inoperable. This is clearly not what we all refer to as Phantom Braking. Something else is broken here other than Autopilot.
Typically when people refer to PB incidents it is when using Autopilot or FSD, not 'just driving around' manually. That was my point, more of a semantics thing. Your incident seems to have been caused by a fault with the car unrelated to AP/FSD usage, that's all. Sorry for the confusion. Hope the car is fixed soon.
Except that is not what happened to that person, theirs went from 45-0mph in seconds (not gradual slow down) and the car disabled completely. That sounds like AEB activation and some other defect in the car that disabled the vehicle (phantom braking does not).
