I have had this happen two times now in the past month, and have a service visit set for 20-Jan. I don't know if it is a braking failure, or AEB kicking in.
In both instances, Autopilot is not engaged, I have been coming up to a redlight where the car in front of me is slowing. I let off the accelerator pedal to start slowing normally (one-pedal driving). I notice the car in front starts braking harder, the red-alert bell sounds letting me know of the upcoming collection. So I move my foot to the brake, press it normally to slow down faster (I am in complete control of the car). My car starts slowing and suddenly the brake pedal goes to the floor, the car makes a lot of noise (I think from sliding tires or ABS) and it comes to a sudden and very abrupt halt, completely scaring the sh*t out of me and disorienting me in the process. After it stops and the car in front of me moves, I can drive normally.
The first time it happened I thought it was a fluke or maybe I hit some sand in the road or something. Then it happened again yesterday and I thought there must be something broken. So I opened a service request and am set to go to the service center on the 20th. I did some reading on this forum and see people talking about the Auto Emergency Braking system, and wonder if that is what is happening. I don't get any type of alert stating that AEB was initiated or anything like that, but the car is definitely taking over and slamming itself to a sudden halt.
Thanks...
