Emergency braking applied when no other vehicles were in sight. Braking was hard enough to spill coffee. Seems to occur when adaptive cruise control is on. Happened about 10 times on recent road trip. Lucky no one was behind us! Felt very unsafe.
2023 Tesla Model 3 driver assistance complaints

The vehicle applied sudden and strong braking in clear road for no reason. It has done it on many occasions in the 2000 miles we have had the vehicle.
My vehicle constantly slows down and occasionally even slams on the brakes to slow down for nonexistent obstacles. I believe this is a serious safety concern if there is a vehicle behind mine, as the driver of that vehicle would not expect mine to rapidly slow down. The root cause seems to be that the camera vision system frequently mistakes certain signs and dark cars reflected in mirages as pedestrians.
I was stopped before turning left into a parking space. I was driving slowly. The car stopped but I did not engage the brake as a Tesla will stop once the foot is removed from the accelerator. At that point the car leaped forward at full speed hitting parts of a building and a fence. I did NOT step on the accelerator. No one was injured. The airbags did not deploy even though there was $17,000 damage to the front of the car. There were no warning signals. The person inside the building was waiting for me and saw the car come to a stop.
The ADAS regularly brakes suddenly for no apparent reason. There does not seem to be a consistent reason. Yesterday, during a 90 mile drive EB on the interstate in the afternoon it braked (scaring us) suddenly so often that it made cruise control more of a hazard than a help. This morning between 9-11 am, westbound on the same interstate it braked suddenly 20-30 times. This sudden braking is dangerous as unexpected behavior could cause an accident with any vehicle behind us.
The car has a tendency when I’m on rural highways to suddenly emergency brake when I have the auto pilot on
On Adaptive cruise control mode about a set speed of 70-75mph on I-5 , the car was suddenly decelerating or braking on Freeway for no reason. I.e. No vehicle or obstacles was there which required braking during approx 3 occurrences happened on a same day of 200+ miles drive. It was deadly dangerous and increases risk for a nasty rear-end crash.
Since purchasing this vehicle in May 2023 I have had four (4) instances of the vehicle automatically braking (phantom braking) while traveling at a higher speed on the interstate using cruise control (Autopilot). This has occurred during both daylight and nighttime driving. At the time it occurred, only once was there a vehicle in front of me, but far enough away that the auto braking should not have activated.
While I was driving along a freeway using autopilot cruise control, the car suddenly slammed its brakes even if there was no cars in front of us. I thought it was just a fluke but it happened at least twice if not thrice during that trip. There was at least an approximate of 3 miles gap between us and the car in front, so practically no cars in front. Had there any vehicles behind us, it would for sure rear ended us.
The contact owns a 2023 Tesla Model 3. The contact stated while driving 70 MPH, the vehicle stopped suddenly without warning. The vehicle was not diagnosed or repaired. The dealer was not contacted. The manufacturer was not contacted. The failure mileage was 5,000.
While driving, both while using Adaptive Cruise Control and while using "Autopilot" (automatic lane centering), the car has severely emergency braked with no input from me. The conditions were bright sunlight, with mirages on the roadway in front of the car. I believe the car cannot tell the difference between these mirages and actual obstacles. The emergency braking is severe enough to potentially cause an accident, with speed rapidly dropping from 70 mph to 45mph. This is a serious defect that needs addressed ASAP.
I have had this car for 6 months. Three times within the past month sudden braking (phantom braking) occurred while driving on the high way with cruise control engaged. The car slowed from 70miles/hour to 35-40 miles/hour without warning on a clear day on a clear road. Then the car picked up speed. The cars in the front and the rear were far away to cause any incident. This happens in a random fashion and cannot be reproduced.
My Tesla Model 3 has had 3 phantom braking episodes since I bought the car new in June 2023. All 3 episodes were when the cruise control was on. Without any warning, the car will violently slow from 70mph to about 25mph in a very short time. My guess, less than 2 seconds. The tires loose grip on the road surface and the car will come to a stop. In all 3 instances, I needed to apply the accelerator to get the car moving again. During all 3 phantom braking episodes, there were no vehicles behind me that could of rear ended me. If so, the vehicle(s) behind me would have no doubt rear ended me. All 3 instances occurred on clear warm days close to Yermo CA on Interstate 15. I reported this phantom brake issue with the local Tesla location and they reviewed my cars software and said nothing was wrong. The system is working as intended. Once my Tesla Model 3 phantom breaking started, I have researched the issue online and noted a tremendous amount of complaints and reports to your agency. This phantom braking needs to be fixed and until then disclosed when a customer buys a Model 3.
When driving in highway using autopilot, the car suddenly slammed on the brakes. This made no sense at all as there were no cars in front of it.
Phantom braking occurred 3 times over the span of several minutes while driving at highway speeds. The first two incidents occurred while utilizing Autosteer. The third time occurred while only using cruise control.
Scenario 1: Driving mid day in hot weather in desert highway with rolling hills and cruise control activated. Upon cresting a ridge with mirages the car slams on the brakes until the mirage dissipates. Also as another car approaches and its reflection is bounced back from the mirage in the road surface the car slams on the brake until the reflection shifts or the mirage dissipates. Scenario two: Driving on freeway mid day in warm weather and brightly illuminated freeway and approaching dark shadows under an overpass. The car slams on the brakes until closer to the overpass. 20-40 mph deceleration noted. The specific freeway section had a slight descending roadway leading into the shadow and then ascended on the other side so that a continuing road surface was not immediately visible beyond the shadow.
We have experienced several episodes of the car suddenly breaking for no reason when using cruise control. The speed is very quickly reduced a good 15 mph without warning.this is not only very alarming as drivers/passengers but it is incredibly dangerous. If there was a car following closely behind us, they would have hit us.
On July 6th, at 6:42pm, while driving 70 MPH on California Highway 152, on a clear day (88 degrees F), with no traffic around our car, the car slammed on the brakes, taking the speed from 70 MPH to 46 MPH in a period of 5 seconds (with most braking in the first couple seconds). I was using the cars' built-in Autopilot system. The car did the same thing about 2 minutes earlier, so we happened to have been recording a video of the cars operation when it happened this second time. The car did the same exact behavior on June 29th at 10:30am, on the same highway but different location. It was also a sunny day, and there were (thank goodness) no cars near us when it happened. That time, it braked so hard it triggered the ABS system.
I was driving on a divided highway in the right hand lane out of two lanes. To the right was a grassy berm. To the left of the road was a grassy median. I was driving with the adaptive cruise control enabled and set to about 70MPH. Full self driving was not enabled. There were no vehicles or other obstacles visible ahead or to the sides, no vehicles following. Without any reason I could perceive, the vehicle abruptly decelerated rapidly. I pressed my foot on the accelerator pedal and the car stopped decelerating and resumed normal operation at roughly 40MPH. If another vehicle had been following me, the unexpected rapid deceleration could have resulted in a collision. This vehicle is a rental car owned by Hertz, and I have not had the vehicle inspected or diagnosed by any dealer, service center, the manufacturer, police, or insurance representatives. The Alert log in the vehicle computer showed at 6:16pm, code EPBL_a180: Emergency brake applied (see attachment).
Tesla has serious safety issues automatic emergency, braking Blindspot warning, Lane, departure warning, and other basic safety features which are very common in the cars these days. I purchased Tesla for my teenage child. In past three months we have encountered multiple instances where Tesla was not able to perform as promised this morning I was driving tesla loaner Vehicle when I was heading to pick up my car and someone drifted into my lane without warning and Tesla did not apply emergency brakes or generated any warning signals. I have notified Tesla service about the incident and past incidents to tesla service representative. Tesla representative at Costa Mesa office opened the service request to get the software diagnosis completed so that they can get to the bottom of it, but [XXX] from Irvine office called me and he is in denial that it is a car issue and blame it on me that it is between the car and the car owners manual, I have requested an escalation from Tesla service Center. In the meantime, I am filing this complaint so that the federal safety agency can start their investigation before. It is too late and some life is lost because of irresponsible behavior by Tesla and send in selling the features which do not work I have Lexus RX 350, 2017 model and all these features work seamlessly in the car , I am shocked Tesla is falsifying and and selling inaccurate features to the consumers which cannot be discovered until it is too late. Please start investigation investigation ASAP. Thank you. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
Multiple times the car while on cruise control has slammed on brakes due to seemingly nothing. It's without warning our alert and it is extremely violent. It happens at least once every week.
While in cruise control vehicle will brake hard as if it detects something in front but there’s really a clear road.
Tesla's traffic aware cruise control (adaptive cruise) frequently brakes hard for no reason (aka "phantom braking"). This behavior occurs multiple times per week during my daily commute on a two lane highway. It happens at different locations, different times of the day, and with or without other vehicles around. "Autopilot" is disabled so there is no auto steering or lane centering. Unnecessary hard braking will significantly increase the chances of a collision with other vehicles, especially with higher levels of traffic. This problem is a well known issue with "vision only" Teslas with no radar and has been documented by many other owners. This issue has been occuring since the vehicle was new and is a system design issue, not a specific part failure. There are no warnings or other messages. There is currently no way to disable adaptive cruise control and use basic fixed-speed cruise control.
Vehicle automatically applies the breaks while using the cruise control. Braking occurs randomly and very suddenly at highway speeds with no warning. The car slowed rapidly to about 25 mph. This has occurred twice in the last 6 weeks in two different locations. Fortunately, there were no vehicles following at a close distance. If there had been, the sudden application of the brakes would almost certainly have resulted in a rear-end collision with the car that was following us.
The 2023 Tesla Model 3 Performance Autopilot cameras "saw" things that are not there while driving during daytime on the highway aka phantom braking. This resulted in quick automatic braking making for a very uneasy drive with fear of being rear-ended when it happens. Yes, my vehicle is available for inspection. Our safety was put at risk due to potential to be rear-ended. Also, this happened on an icy road which has potential to cause sliding. I called the Tesla sales department where I purchased the vehicle. They said there was nothing they could do and that Tesla is working on it. There are many websites discussing the problem. My vehicle has not been inspected by Tesla. They told me there is nothing we can do. I have not contacted my insurance company or police. I'm not aware of any warning signs. You are driving on a highway during the day at 80 mph, the car's cameras "see" something that is not there, and it automatically brakes hard.
I was driving from Palmdale, CA up to Mojave, CA at 7:05PM on June 16. The car was close to Rosamond, CA on the highway when it engaged FULL brakes. I started in the right lane, the autopilot was ON and set to 79MPH. The only cars visible on the highway were my car and the car in front of me. There were no other cars immediately visible to me or autopilot in front of me or behind me - other than us two. My car was traveling faster than the car in front of me, so at ~3-5 car lengths I started a left turn signal to merge into the left lane, and overtake the small car (silver Toyota?) in front of me in the left lane. When I started the left turn signal the autopilot disengaged as expected. I got in the left lane then stopped the signal, and turned ON autopilot @ 79MPH. My car started overtaking the car in the right lane, the car beside me was now in my right blind spot. Then all of a sudden my car engaged FULL brakes and went from 79 MPH to maybe 30MPH? As a reminder there were no cars in front of me or behind me. The other car was to my right. I quickly assessed the situation to confirm I wasn't going to be rear ended by the car to my right and pushed the gas peddle as hard as I could to accelerate back to 70+ MPH. I checked to see the sun was behind me so the car's cameras were definitely not blinded, I sped far enough away from the car next to me to take a photo of the area I was driving in. Please see the photo attached to see the condition of the sky and to confirm the roads were completely empty when the tesla decided to brake in its full capacity for what I believe to be no reason at all. I fully believe if there was someone behind me in the left lane even at a safe distance I would have been inadvertently rear ended as there was no reason or cause for the car to be breaking that hard. I'm sure Tesla can provide telemetry data from my car to corroborate my version of the events.
Car unexpectedly brakes while using the cruise control. This can occur multiple times on a long drive without warning and for no apparent reason.
On several occasions ( 8 or 10 times) while driving at highway speeds, with little traffic, on an extended trip, the vehicle suddenly applied the brakes for no apparent reason. I have learned that this is called "phantom braking". On one such occasion, I narrowly avoided being struck from behind by another vehicle following me by applying the accelerator. I have not yet reported this problem to Tesla, but intend to.
While driving on 15 freeway between Riverside CA to Las Vegas NV, I put the car in cruise control. While near Barstow, the car hard brakes dropping speed quickly. Luckily no other car was near. I changed lanes to pull on the side as I wasn’t sure what was happened, as it actually felt like the car had locked up. I did take the car out of cruise control and that seemed to fix the problem. I’ve used cruise control before and the adaptive braking has been manageable, this was extreme. On 4 June 2023.
When adaptive cruise control is engaged, the vehicle harshly brakes. This occurs very randomly and is abrupt. The operator needs to quickly take control and accelerate as the speed is reduced significantly. One incident, the speed was 80 mph and it reduced to less than 60.
