2021 TESLA MODEL 3 Complaints

Driving on an open 2 lane highway between Lecanto and Gainesville, car slammed on the brakes while in autopilot. There were no obstructions or other reason to stop.

Similar to the reporting of others, I wanted to confirm that we had a problem with our Tesla 3 auto-pilot feature erroneously triggering emergency braking by misinterpreting oncoming traffic. This happened twice in a similar situation. While driving on a single-lane highway in auto-pilot, the car abruptly braked when a semi-truck passed in the opposite lane. This sudden deceleration could have lead to a rear-end collision but fortunately the driver behind had left enough breaking space. The same thing occurred again on the same road - also with a semi-truck in the opposing lane. This time, vigilant that the auto-pilot might be malfunctioning, the sudden breaking was quickly overcome by pressing the accelerator. There is no doubt on our end that the current version of the auto-pilot will trigger emergency braking mistakenly based on misinterpreting opposing traffic.

The car was on FSD jerked right toward a semi truck then jerked left toward the posts in the median as it was accelerating and FSD would not turn off. Was trying to control the car but it kept pushing and accelerating causing us to crash in to the median posts. Normally FSD would turn off if it was unsure but this day it would not. Plus other times it would phantom brake if we were on 2 lane road and met on oncoming large truck. We also had other times of phantom braking going over a hill. We have reported this to Tesla but no response yet. We owned this car 11 days when our wreck happened.

While driving on the highway without any cars in front of ours, three times the vehicle slammed on the emergency braking system and attempted to stop the car causing cars behind us to slam on their brakes to avoid hitting ours.

My 2021 Tesla model 3 has a issue of what is called Phantom Braking. On 2 lane undivided highways and on all types of roads the car will randomly slam on the brakes to what I assume is to prevent hitting a obstacle that doesn’t exist. The car will apply the brakes extremely fast and drop roughly 20 MPH or more in just a few seconds. I am unable to use cruise control on 2 lane highways because it slams on the brakes it seems like anytime it sees a dip in the road or a mailbox on the side of the road it triggers the emergency braking system. I feel lucky that no one has been behind me while these events have happened. It happens almost every time I drive the car. I have contacted Tesla about this issue and they say everything is fine and they would rather have a lot of false positives than to miss a actual event. I feel like it is a very unsafe feature and needs to be addressed because other manufacturers have this down with hardly any issues. This has been happening on the car since it was new and has not improved the car has 7500 miles on it.

When in Autopilot mode, the car will sporadically brake without any obstacles in front of it. This has occurred to me about half a dozen times. Always on the highway. Initially it would happen in the daytime near overpasses or when entering shade from a sunny area. Twice it occurred to me at night, on a well lit interstate in an urban area. This is often referred to as Phantom Breaking.

I was driving my car and had it on autopilot. The road was empty and all of a sudden the car decided to apply brakes when nothing was infront of it. I was able to take control instantly to prevent a sudden stop however I was lucky there were no cars behind me

With the Autopilot engaged on the freeway I have had several of these phantom braking experiences but last night I was lucky to avoid a accident with the car following me.. This happened at 74 miles per hour with the autopilot engaged the brakes slow me down to 60 miles per hour before I could disengage the autopilot.

When the vehicle is in autopilot at high speed, it breaks suddenly without any visible obstacles. This happens at Kraft once every 200 miles of highway driving with autopilot on. The speed drops suddenly from 75 mph to 40 mph.

The car has twice gone into emergency braking mode on the interstate for no good reason. One incident was as the car was approaching a dark shadow area under an overpass, and the other was in a construction zone and I have no idea what triggered it. In both cases if someone had been following closely I may have been in trouble.
