2021 TESLA MODEL Y Complaints

phantom braking, my car have driven 13.6K miles in the last 1 years. It happened once on the city street (early morning with no cars on the road and twice on the freeway, both time I was next to a big trailer truck, and no cars behind me, lucky.

Automatic Emergency Braking. Known also as "phantom braking." Tesla is aware of the problem. Regardless of whether or not I'm using the standard cruise control or the more advanced full self driving feature, the car routinely hits the brakes even when there is no obvious obstruction in front of it. If the car suddenly brakes on the highway with another car behind it, it risks a rear end collision. No other warnings appear. The car simply brakes for no reason. This automatic emergency braking system should be removed for standard cruise control. It's more of a hazard than a benefit.

When using cruise control. My car will phantom brake. Most of the time it is when oncoming traffic is present… but a few times there are no cars around me… a few weeks ago, the car phantom brakes on an ice patch almost causing a wreck.

I drive on the highway from Dallas to Austin to Houston every week. Every trip I have about 2-4 phantom braking incidents at full speed. It seems to occur at similar points every time. It is incredibly alarming and I have to slam on the accelerator to not cause an accident. This needs to be repaired.

In short: Phantom Braking While driving on single lane highways with Autopilot enabled my car slams on the brakes and alerts whenever a semi is safely approaching. What component or system failed or malfunctioned, and is it available for inspection upon request? - I assume the Tesla Vision System + Autopilot are what fail in this scenario. How was your safety or the safety of others put at risk? Immediately this puts us in risk of a rear end collision. Alert fatigue from false alarms creates a long term risk as drivers are trained to ignore / cancel alerts. Has the problem been reproduced or confirmed by a dealer or independent service center? Not explicitly. We have mentioned it to a dealer and said it was a common complaint. Also it is a well known (under addressed) issue amongst Tesla owners. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, given the lack of property or personal injury it doesn't seem right to alert those institutions. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, all systems appear to be functioning correctly. That is a large part of the problem - if the Tesla Autopilot is unable to function reliably on one lane highways it should at least warn drivers.

(1) My car dangerously and aggressively applies the brake dropping the speed of the car between 3 to 30 mph within a second or two (phantom breaking) EVERY SINGLE TIME I drive the car in adaptive cruise control or auto steer. This happens on 2 lane roads, on divided highway, driving on straight and curvy roads, when there are shadows, frequently when a truck or car is coming toward me, and even on overcast days when driving on a freeway when there are no shadows and no traffic in either direction. The car seems to be sensing an object that is going to cause a collision and applies the brake even when no object, threat, or shadow is anywhere in view in any direction. I frequently have to immediately step on the accelerator to keep from getting rear-ended in what could be a severe or fatal accident. (2) On a 225 mile drive to the Tesla Service Center to correct the phantom braking problem, my car inappropriately applied the brake 40 times, including aggressively dropping the car's speed from 63 mph to 35 mph in a second or two. (3) My car dangerously and aggressively applies the brake whenever a car is turning in front of me that is sufficiently far enough away that there is no absolutely no threat whatsoever of a collision. I then have to quickly step on the accelerator to keep from being rear-ended. (4) I have taken the car into the Tesla Service Center twice to correct this problem. I even gave them a list of dozens of times/dates I experienced phantom braking and the # of mph the car slowed (I recorded this on paper and as "bug reports" on the car's computer). On one visit the technician spent 12 hours reviewing my bug reports and the car’s operation. In both of my Service Center visits the bug reports were sent to a Tesla engineer for review. After both visits to the Service Center I was told the technician and the engineer could find nothing wrong with the car and “it was working as designed.” (5) In conclusion, my Model Y has a SEVERE safety defect.

The contact owns 2021 Tesla Model Y. The contact stated that while driving approximately 55 MPH with the vehicle on auto pilot, a large commercial truck in the opposite lane passed the vehicle, which then applied the brakes and slowed from 55 to 35 MPH. The contact stated that this should not have happened and was an instance of "phantom braking". The contact reported that once the commercial truck passed the vehicle went back up to speed within seconds. The contact stated that he did not notice if a warning light was illuminated, but the contact stated that he heard the vehicle sound an audible beep. The contact did not take the vehicle to a local dealer to be diagnosed. The vehicle was not repaired. The manufacturer was not informed of the failure; however, the contact went to the dealer to report the failure. The failure mileage was approximately 1,000.

Unexpectedly slamming on my brakes in response to imagined hazards, such as oncoming traffic on two-lane roads. This happens often and I have to shut off this feature to avoid a spin out on icy roads. Very hazardous. overly sensitive to trucks in the opposite lane. Car lurched from 50 mph to a near-stop in response to a large truck. Is this phantom braking?

While using cruise control, aka “Autopilot,” the brakes automatically engage, even with no reason to. It’s happened so many times at high speed, and while passing, that I am now scared to use “autopilot.” While using autopilot, I have to be ready to mash the accelerator peddle at any moment, due to unwanted breaking and it feels very dangerous. It can also be traumatic for passengers when the vehicle suddenly brakes hard at high speed. I’m worried it could also cause an accident if someone were right behind me and also traveling at a high rate of speed.

Driving a 4 lane road with not other vehicles in site the car suddenly braked to the point of locking up the seat belts and throwing items around the cabin. I reported this to the manufacturer and they were able to review logs and confirm that the car mistakenly saw something and applied the brakes. I would have been hot from behind if a car was following. I was told not to use this feature on certain roads. But I asked how to disable it I was told there is no way. This needs to be addressed before there is an accident. I was not using full self driving. I only had cruise control on.
