The adaptive cruise control system routinely applies the brakes when there is no lead traffic on a completely open highway. I’ve had multiple instances where the car decelerated from 75 to 45 mph before I could react and press the accelerator to correct the state. During these events, the car does not indicate any type of emergency warning (no forward collision warning, no emergency braking warning). This poses enough of a safety risk to cars behind me that I will no longer use Tesla’s adaptive cruise control feature.
2023 Tesla Model Y driver assistance complaints
Page 18 of 19: complaints 491 to 520 of 549, newest first, as owners wrote them.
The adaptive cruise control slammed the brake when driving over a highway overpass. Tesla slammed the brake from 75 mph to 50 mph. Luckily there was no car behind. Clear sky around noon time.
While driving South on I75 near Tampa Florida using Autopilot the car suddenly decelrated to 10mph. There were no cars next to me and we were passing through a 6 lane area where the road splits. No distinguishing features, no cars on either side and we were heading slightly up hill. It seems like the cameras could only see the sky. Fortunately there was no car directly behind me. Very scary.
The contact owns a 2023 Tesla Model Y. The contact stated that while driving approximately 62 MPH with the autopilot mode activated, the vehicle experienced phantom braking. There were no warning lights illuminated. The manufacturer was not made aware of the failure. The vehicle was not diagnosed nor repaired. The approximate failure mileage was 3,000.
Tesla model y 2023 phantom braked on the intestate. The emergency braking system and adaptive cruise are not correct. I almost got hit because my tesla auto pilot braked on the interstate for no reason.
Took 1st long trip with the Tesla. I had "phantom braking" happen 5 times while on the trip. Once on the way to the destination. Then, it happened 4 times on the return trip home in a span of 2 hours. This was in the first autopilot mode (Traffic-Aware Cruise Control), not the Autosteer version. Each time it happened on an open road in a rural area at a speed of around 70mph. This puts my vehicle and others at risk where someone that is close behind me would be surprised with a sudden decrease in speed and cause an incident. It also is nerve-wracking to the driver and passengers of the vehicle. This problem is known within the Tesla community and was reported to Tesla. The vehicle was "inspected" by looking at incidents in the cars software log. The Customer Service agent could not confirm any incidents and asked that I file a "bug report" through the car immediately after it happens again. There are no symptoms or warning of the problem - it happens at random.
New car with less than 1800 miles. Multiple times where The car will frequently and unexpectedly slam on the brakes while in autopilot on the highway. Almost caused an accident twice and I was terrified. Did not know about this problem but this can cause an accident.
I got the delivery of the car VIN [XXX] on March 10 7 PM and got the car out and drive to home from Kennesaw tesla delivery center. On my way home the car stopped right after crossing the light signal at the intersection of Medlock bridge rd. and parson rd. And it does not move, I had to turn on the emergency lights to save myself from accident and the cop had come after some time. We were lucky to save ourselves without an accident as the car stopped all of the sudden and there was no car behind. I think this is a problem with the car and needs to be inspected and nobody should be in this situation in the future. I want to raise this as a safety concern please for Model Y in the very first hour after the delivery of the car.

Car was purchased December 30, 2022. The first time I engaged auto pilot, an oncoming semi was in its lane and my car slammed the brakes on while on auto pilot. It happened the next time I used auto pilot with zero perceived “threat”. I was extremely hesitant to use it, henceforth. I tried auto pilot over and over with my foot, poised and ready to take over the throttle, and my hand poised to disengage auto pilot. 12 times it slammed the brakes on-every time I used the feature it randomly braked, there was absolutely nothing around. These incidences were on two lane highways, no oncoming traffic, nothing in the road. Phantom braking. I do not feel safe using this feature on my brand new car because if someone is traveling behind me, it will cause an accident. I took my car in for minor service (for adjustment and stern issue) shortly after purchasing and mentioned this to the Tesla service Center representative. She said to me, “oh yeah, it does that sometimes. You have to be ready to take over.” Even being poised and ready to take over, I fear my reflexes will not be fast enough if there were someone traveling behind me at 60 mph. and it certainly isn’t how cruise control should work. I have a second service appointment, and actually noted the phantom braking (I subsequently learned this is what it’s called after googling, “random, braking with no threat Tesla model Y 2023”) on my service request to ensure that it has been documented because it’s a problem. A dangerous, unacceptable problem that needs to be fixed. My service appointment is 3/28/2023. Thank you.
The contact owns a 2023 Tesla Model Y. The contact stated while driving 40 MPH with the Autonomous Self Driving feature activated, the vehicle abruptly stopped without warning. The contact was then able to accelerate, and the vehicle started operating normally. The vehicle was not diagnosed. The dealer was contacted, and the dealer stated that should the failure recur, the vehicle needed to be diagnosed. The manufacturer was contacted, and the manufacturer stated that the vehicle needed to be diagnosed. The failure mileage was 1,250.
Bought 2023 Tesla Model Y on 29-Dec-2022. Noticed that when I am backing up the car, even when there is another car right behind, or any pedestrian crossing there was no warning. At first I thought some settings is turned off. Later, when I was changing lanes in freeway, no lane departure alert. Also no blind spot chime came on even though that option was turned on in settings. Almost I was about to crash into another car which was in my blind spot. I started googling and learnt that Tesla has removed ultrasonic sensors from Oct2022 onwards and they are working on Tesla Vision which is a camera based system. But Tesla vision is not ready as of 08-Mar-2023 when I am writing this. How is the 2023 Model Y manufactured without ultrasonic sensors and no Tesla vision passed basic safety test? I feel threatened every moment I drive the car without these basic safety features like rear object detection while backing up, lane departure alert, curb sensor alert, blind spot warning. I feel like I am driving a 2000 model old car which doesn't have any of these features. How does the federal safety agency deem Tesla cars manufactured after Oct22 safe on roads? I will be at financial burden and stress and risk of death without these basic features in a 70k+ car. Why is Tesla even allowed to make such low standard cars without any of the basic safety features? Attached screenshots of my chat with Tesla service also attaching the link Tesla support gave me as ref - https://www.tesla.com/en_eu/support/transitioning-tesla-vision Please investigate this issue and stop Tesla from making and selling unsafe cars for huge price and making profits but doesn't have the basic ethics to care about customer safety. Thanks
The USS Park Assist safety feature was eliminated from the vehicle without providing an alternative method or feature to monitor the front of the parked car in case an object or child was placed in front of the car after it was parked. The original USS Park Assist feature would detect this but the current Vision feature would not if the object or child is closer than 3 feet. It is irresponsible for a car manufacturer to eliminate a safety feature without providing a similar function as a substitute immediately. Just promising that this will come in the future should not be acceptable to the federal safety agency. No problems have been recorded to date but this is just an accident waiting to happen. I'm asking the federal safety agency to contact Tesla to require an immediate resolution.
We had 2 phantom breaking occurrences while in Autopilot traveling at 75 MPH within 10 minutes. The first time we were passing a pickup with trailer on the right and the in the second a pickup was passing us on the left. in both cases there were no other vehicles or objects on the road in front of us. If there was a vehicle following close behind us there could have been an accident. We did not come to a complete stop but I am not sure if that was because of Autopilot or my reaction. There were no other warnings.
Vehicle brakes suddenly while driving even when there are no cars or obstacles of any kind in front or even in the distance. This has led to several events where I was almost rear-ended because of how strongly and violently the car was breaking on the highway. Last example was on March 5th 2023 at 1:19 p.m. while driving on interstate 90 in Ohio going westbound, there were no cars in front or in the distance in the lane. The car suddenly applied the brakes in a very strong fashion in the middle of the highway. There were at least five examples just like this one which happened prior.
I was driving on East on I-8 and was East of Yuma, AZ. I was using the enhanced auto pilot feature. I was traveling 70 miles per hour (5 below the speed limit) There were no autos in front of me and nothing on the shoulder. There was a semi truck behind me (I am not sure how far back.). My car suddenly put on the brakes and rapidly slowed down. (I am not what speed) The de-acceleration was so severe that my coffee cup too flew onto the floor. The semi truck was able to move to the right lane but blew his horn loudly. It was extremely scary and dangerous for both of us. I have done some research and this seems to be a problem that many Tesla owners are experiencing. This issue needs to be fixed immediately.
The Tesla Model Y Blind Spot warning system does not accurately detect the position of cars in the lanes next to the car. The display shows the car as behind the vehicle while it is actually at the rear quarter panel. There is only an audio warning if the turn signal is activated. The car is in the blind spot yet the system does not warn the driver. I took the car in for an adjustment to cameras and Tesla said they are functioning as designed. Tesla removed the radar sensors that aid in parking at low speeds. This was intended to be replaced with Tesla Vision. Tesla Vision functionality is not yet available. Although a low-speed collision with an object may not result in injury to a person, it is a safety feature that has been removed. The windshield wiper's speed cannot be adjusted or even started on the stock. To change speed or turn on the wipers you must look away from the road, locate the control panel and then select the desired speed. This clearly is a safety hazzard.
On February, Friday 17th, 2023 around 10:15pm on 287 exit ramp towards rte 78 west , a truck with a flatbed suddenly went from right to left but the car failed to detect that and we almost collide into the back of it. Collision was avoided only by driver reaction. All collision warning systems failed to detect the situation. Still this is the same behavior we have seen since we bought the car. There is no awareness of close proximity objects. Tesla is acknowledging that critical ultrasound sensors were removed from the car.
When using the cruise control function (not hands free) we have experienced multiple disconnects from the cruise control which puts the car into a sudden breaking condition slowing the car until the cruise control reconnects automatically. On a recent road trip we narrowly avoided a serious accident when this happened and we had a big rig truck behind us. We reported this to Tesla and their emailed reply said the cause was "map data, speed limit data, GPS position inaccuracies or predictive position inaccuracies." We drove over 2,500, mostly interstate highways, and in our opinion, none of their reasons for this condition apply to what happened to us. We set up an appointment with Tesla to look at the car but their email response seemed to indicate that as we drive the car more, the system will correct itself. In our opinion, this apparent software glitch is serious and can have fatal consequences. We have spoken with other Tesla owners and they are also aware of this chronic problem. We are reporting this matter in hopes that it will be investigated and promptly correctly before lives are lost.
Driving on highway with cruise control activated. No traffic around. Experienced phantom braking taking me from about 80mph to 65mph before I was able to react. Had this happened in traffic there is a good chance i would have been rear ended. No notifications or emergency lights appeared on my dash.
This 2023 model Y has no collision warning. This was not what I expected when I purchased.
Twice while driving in early afternoon on very bright days in the direction of the sun I've received forward collision alerts for no apparent reason. Due to adrenaline I don't remember if I slammed on my brakes or not, but I hope I did. Given that there was nothing in front of me for a substantial distance sudden braking for the alert would have been like a brake check had another vehicle been tailgating me. Date is for most recent occurrence, first occurrence was a few weeks ago.
This “phantom braking” issue MUST be resolved! This happens 2-4 times during a 700 mile trip. THIS IS A KNOWN ISSUE. At highway speeds or less with only the cruise control on the car will abruptly slow down as if there was something in front of me but nothing is there. A member of my family no longer wants to drive the car because of this. It’s scary. When it happens, she screams! Fortunately, no one has been behind me close enough to cause an accident. Once we had AEB automatic emergency, braking turned off and it STILL happened! It happens day and night, dusk, and dawn and 40 mph or 80 mph. If you were using cruise control, it can happen at any time.
In auto pilot mode , my Tesla suddenly applied emergency brake and brought my model y from 65 to 10 min in 287 Highway. Luckily they was no car or truck behind me. No car in front of me also.
Car did phantom breaking when I was driving with my wife, 2 kids and Niece from NJ to Pittsburgh, PA. I was driving on autopilot and There was no car in front or on side and yet it suddenly applied break and car went doen to appx 40 mph. Luckily the car behind was at distance and they managed their breaking well. I see it as a big risk to me and my family while being on long rides on autopilot.
While in Traffic Aware Cruise Control (adaptive cruise control), the vehicle will brake hard suddenly with no objects anywhere near it. This has happened primarily on the freeway and luckily no cars were following close enough behind to cause a collision. This is very concerning as it is occurs in inconsistent situations and is completely unpredictable.
On Saturday, February 11, 2023, my wife and I were driving on the highway. I was the driver and I was utilizing the adaptive cruise control set at approximately 75 mph, which is the speed limit. There were no vehicles or objects in the roadway in front of us when all of a sudden, the vehicle automatically braked hard. My wife and I were startled and thrust forward in our seats. I quickly pressed the accelerator and looked in my rear view mirror. I saw a red truck that had been behind me had to veer off into the shoulder of the road to avoid hitting me. Another vehicle was next to him in the passing lane and was also braking. This was very shocking and disturbing that we narrowly avoided a major crash. We had previously experienced this "phantom braking" during a roadtrip a few weeks ago. At that time, we reported the problem to our Tesla dealer and they sent a technician to our house on Feb 3, 2023. The technician told us that we were experiencing this phantom braking and all of the newer Tesla's had this problem. He assured me that the "engineers" were working on it and would have a solution soon. He further told me that there have been no reports of any accidents, injuries or deaths as a result of this phantom braking problem. That was reassuring at the time. With this latest incident, I find it hard to believe there have been no accidents. The only reason we did not have a bad wreck is because of the skill and attention of the driver behind us. We reported this latest incident to our Tesla dealer and were given the following reply: "As mentioned in the previous messages, unwanted slows do happen and are expected. As we develop the system and the firmware, this will get better over time. At this time, we do not have an immediate resolution for you." I have never experienced a safety issue with a vehicle to the caliber of this magnitude. I am shocked this is allowed and acceptable. I am truly worried for our safety.
Was using the adaptive cruise control in addition to lane keeping assist, collectively known as Autopilot. Was in the left most lane with no cars in front or beside and a car about 5 car lengths behind when max auto regen occurred aka "phantom braking". There were no indications of obstacles in front based on the screen rendering.
I was driving highway on 2/13/2023 around 11:12am. Traffic was clear, weather was good, I was using autopilot with Tesla model Y. The car decided to break at highway speeds for no reason. The breaking was very aggressive and I was very scared. There was no accident but something is not right with autopilot of Tesla. The car is new and using latest available software update.
The contact owns a 2023 Tesla Model Y. The contact stated while driving 75 MPH, the vehicle abruptly stopped independently. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 1,300.
When autopilot is engaged the car slows down without warning and there isn't anything in front of the car. We had close calls with cars behind us when the car applies the brakes for no reason. The wipers would come on for no reason and as long as the autopilot was on it couldn't be turn off. So we had to disengage the autopilot and turn off the wipers and drive another 300 miles without autopilot for our safety.
