My husband and I were driving from Cincinnati Ohio to Harrisburg, PA on Monday, Oct 16, 2023 on the highway (turnpike). At least four times the car tried to kill us by starting to slam to a stop ON THE HIGHWAY when using cruise control. Fortunately each time there were no cars immediately behind us or we would have had a major accident. We stopped and called Tesla in Mechanicsburg who consulted with someone on another line. We had both hands on the steering wheel and were doing everything correctly. They concluded that it was either the car sensing we were driving near mountains, or around curves. it happened once with a mild curve but the other times the road was straight. There was a small drizzle of rain (they said it could be rain) or they also said it could be sun. At this point I said "this is ridiculous as how can we drive this car to Florida (in the sun) if this might happen. Their conclusion: Take it off cruise control. We did and continued home but it is ridiculous that we cannot use the cruise control for fear of it happening again! And they said risks include mountains, rain, sun and curves in road. These conditions are the conditions almost everyday for most people in Pennsylvania! If there had been a truck behind us or a car, we would be dead.
When on autopilot mode with traffic aware cruise control (TACC), the Tesla model Y car gets unexpected unpredictable random sudden slowing down with braking causing panic, inability to react, unsafe for the following car the rear. Appears to have unexpected unnecessary phantom braking unsafe for driver, passengers and the rear following car.
Car was on TACC. It was early evening so the sun was making a lot of shadows on the road from trees. Car kept repeatedly slamming on the brakes approaching each tree shadow. The road was absolutely clear of any real hazard. Almost caused car behind me to collide into the back of me, and then they passed me while honking and very angry. I can't blame them.
Two times in one week with two different drivers driving the same vehicle the vehicle experienced sudden unintended acceleration while parking. In the first incident this resulted in damage to the bumper into a wired fence which the vehicle did not alert but rather accelerated instead of applied regenerative breaking. Four days later the same incident happened with sudden unintended acceleration occurring while parking the car. When sending the car to Tesla for service due to the safety concern and damage this resulted in they said this was a user error which can’t be the case as this incident happened with two different drivers driving the same vehicle. When reading about this there have been numerous complaints which have shown that there is an electrical “ They show that the sudden unintended acceleration of Tesla cars may have been caused by negative voltage spikes that are logged as a fully depressed pedal, fooling both Tesla and the federal safety agency investigators that there has been no hardware or software defect.”
I received this new car 11 days ago - it has none of its safety assist driving features and Tesla is not responding to my requests for assistance. I can't get a response to my requests for help. The clearly is absent of multiple points of functionality. Thank you
While driving on the highway, I had set the cruise control to max 65 mph. After some time it suddenly set the cruise control to max 35 mph and suddenly reduces the speed even though all front vehicles were running around 65 mph. It was incredibly dangerous and the vehicle behind me was about to hit.
I was driving at a very slow speed of 1 mile per hr as I entered into the Kohls complex in Pleasanton ca. Then as I was pulling the car to a parking spot, all of a sudden I felt the car accelerated on me. My foot was always on the break and I pressed the break but the car still accelerated at a speed I had no control and it went over the parking bump and hit 2 cars that was parked opposite. I felt out of control and scary because the car was not doing as intended, to stop when pressed the break. I then pressed the park button. Then I also reversed because the car was not stopping. There was totally 4 cars damaged including my car. 2 opposite and 1 parked side of me. I could feel the sudden acceleration in the car and out of control feeling. Luckily there were no people in other car so no one was hurt. I was also not hurt. - Not sure what malfunction happened , but the break in that instant of time was not acting as it should for few seconds. Yes, the car is available for inspection - My safety was at risk as the car was no behaving the way it should and I got scared as to what would happened next. Since there were no people in the other car, there was no risk. but if there were they probably would have got hurt. - I reported the issue to Tesla center. They said they will look but never heard back anything from them . - None of them has inspected the vehicle yet. - No warning signs were there. after it hit i could hear the beep
My wife pulled into our driveway at 5 mph. Suddenly our Tesla Y. Auto accelerated,before my wife could realize it ramped into our garage through the door and collided on the wall of our Laundry room and kitchen damaging Foundation of the laundry room.My wife was also injured badly. This incident has shaken my wife. We complained to Tesla and filed the complaint but they are not even following up. Please investigate this issue
I bought a brand new tesla, only to find out that it was not emitting any sound slowly driving forward, but only when in reverse. I read through the cars manual and there it says the car should make a sound moving forward under 19mph, to warn pedestrians of the oncoming tesla (my car). If the car does not do that, then to immediately contact Tesla service. I did that and Actually so was there at my Tesla service station in Burbank CA in person and they said to me, I should not worry what their own manual for the car says. The car is not to make a pedestrian warning sound forward, but only when in reverse. To be honest, that seems wrong to me. Please advise. Thank you for your time and consideration. Kind regards, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Abrupt, rapid, unannounced deceleration with no apparent cause. Has happened multiple times.
The car was going at the speed limit or maybe 5-9 miles over speed limit when brakes were pumped to stop car as there was stop and go traffic on a bridge in bay area (CA). The car had quite a distance from the car in front of it. Despite brakes being applied, the car seemed to accelerate and brakes had to be applied hard. However, the car did not stop until it hit the honda in front of it. As the driver of the Telsa at the time of the accident, it seems as though car was accelerating despite brakes being applied. A huge sound was heard by me the driver and then the driver eat belt became malfunctioned and the car would not restart. After a few minutes, the car restarted but now the dash board states service needed and I could no longer fasten the seat belt. The front of the car appeared to have minimal bumper damage but the seat has not worked since the accident.
I was pulling up to a ticket machine in a parking garage. I had my foot on the accelerator and was using regenerative braking and was essentially stopped. I was short a few inches from the button to get the ticket so applied almost no pressure to the accelerator – more like a tap so I could go forward a few inches. The car went into full acceleration mode, broke through the ticket machine barrier and kept accelerating. As soon as I sensed going forward too fast, I took my foot off the accelerator and put it onto the brake. I did not feel any response from the brake. With my foot. I managed to steer away from a wall in front of the car but hit a parked car. The impact pushed that car into a second car and then that car pushed into a third car and the third car pushed into a fourth car. My car was totaled as well as three others. Fortunately, the impacted vehicles were unoccupied and there were no pedestrians. No warning beeps or emergency braking occurred. One of my passengers had minor injuries (3 fractured ribs). A police report was filed. Previously (3 or 4 weeks prior to crash) I had an incident in an above ground parking lot. I had pulled into a parking space, backed up to straighten out then was pulling forward towards the curb. I took my foot off the accelerator, but the car kept going very slowly instead of regeneratively braking as it had done before. I put my foot on the brake. It was unresponsive. I kept pressing and finally it engaged, and I was able to stop the car about five feet over the curb and into the grass.
I bought Tesla in May 2023. My Tesla Model Y has suddenly accelerated in my garage on 08/29 @8.25pm EST and damaged my garage front door/drywall and broken my stair case in pieces. It was phantom acceleration. I have video from my ring security system camera video which shows clearly that I was parking in my garage extremely carefully, however the Tesla Model Y suddenly accelerated beyond my control (I was not accelerating) and put me under risk and damaged my property. I have auto insurance to cover my Tesla car damage. However, my biggest fear is how can I use this Tesla Model Y when we see this life threatening behavior. This unintended acceleration can put my life and others life into danger. I would like help from the federal safety agency to ensure my Tesla Model Y is defect free. I just bought couple of months ago. I would like to request the federal safety agency to help me get this product replaced from Tesla motors. I am afraid to drive this vehicle now. I am currently going through a big shock, trauma and fear that I may have severely injured people on the road or my family members in garage if this unintended sudden acceleration would have happened around them. The damaged vehicle is outside my garage. It is not drivable. Vehicle front bumper is completely damaged and fluid has been leaking. I have filed insurance claim. I don't know what should I do right now. I would like to seek advice from legal sources on my options. My car is covered under my insurance, however I don't know if my car is fixed - I can drive this vehicle with confidence due to this strange unintended acceleration issues. Please help me at the earliest.
This is a report of a RECURRING problem commonly known as "phantom braking." When I take long trips in this vehicle at legal freeway speeds and with the Adaptive Cruise Control and Auto Steer (lane keeping) functions engaged, the vehicle will occasionally reduce speed suddenly and violently (emergency braking) even if there are no vehicles ahead and no visible hazards whatsoever. This occurs without warning and for no reason when cruising on open, straight interstate highways. In a typical 5-8 hour driving day on long trips, this will occur 1-2 times daily. If other vehicles were to be following closely behind, this would certainly cause a serious rear end collision or pile up. The vehicle gives no advance warning and no alarms sound. The car just brakes suddenly and violently scaring the bejesus out of my spouse. I have learned to step hard on the accelerator the moment this occurs which will partially offset the severe braking action so that any vehicles behind do not need to brake suddenly. I do wonder what the heck any drivers behind think when they see the Tesla suddenly brake hard then accelerate immediately back to speed. I worries me too that some aggressive driver behind might think I am doing this intentionally and get into a road rage incident with me. People have been shot and killed for less. I don't understand why this has not yet been addressed seriously by Tesla or the federal safety agency. This is a SERIOUS and dangerous defect! Thank you.
Concern: The "Autopilot" system in my 2023 Tesla Model Y AWD LR has shown diminished performance, particularly in adaptive cruise control, compared to the 2018 Model 3 RWD Long Range. Account: I aim to notify the federal safety agency about a concerning "Autopilot" behavior in my 2023 Model Y AWD LR. I am comparing this to the performance of my previous 2018 Model 3 RWD Long Range, driven under similar conditions. Incidents: Near Accidents: During commutes, my Model Y AWD LR frequently doesn't slow timely. In some cases, I've had to override Autopilot and brake abruptly to avoid collisions by risking letting the car either fail to brake fully or slam on the brakes so hard. The car's sudden deceleration at the last moment is concerning as it is not only a dangerous scenario for myself and my occupants, but also other drivers behind me, who might also crash. Conditions: These instances took place during daylight with a spotless vehicle, ensuring no camera obstructions. Settings: I set the distance threshold between levels 4 and 5 and ensured the speed was no more than 10 mph above the speed limit. Lane Keeping: The lane-keeping function is efficient. However, adaptive cruise control's reliability is questionable. Sensor Absence: The 2023 Model Y lacks radar and USS (ultrasonic sensors). This could be affecting the performance drop I've noticed. Accidents: Due to these issues, I've narrowly missed three accidents just this week alone, endangering my safety and others. Conclusion & Request: While Autopilot should enhance safety, my experience with the 2023 Model Y AWD LR suggests otherwise. This unexpected performance dip, especially with supposed hardware upgrades, is alarming. I urge the federal safety agency to investigate this issue swiftly. Given the popularity of this model, many drivers could be at risk.
I was trying to make right turn from Mcdonald's but suddenly, unintended acceleration, Tesla went into the intersection and hit the other side of car. - The emergency brake did not work and as a result of the accident , there was a severe damages in the front of the Tesla.
The contact owns a 2023 Tesla Model Y. The contact stated that while attempting to park the vehicle, the vehicle accelerated unintendedly. As a result, the vehicle jumped the curb and crashed into a barrier wall. The air bags did not deploy. No warning lights were illuminated. A Police report was not filed. There was no injury sustained. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 1,800.
On 2 occasions, my 2023 Tesla Model Y, accelerated more than expected with the slightest pressure to the accelerator pedal. No one was injured and no damage done, however, damage and injury COULD have resulted if this happened at a different place and time. At this time, I have not contacted the dealer as recent Google searches revealed other such complaints having been reported. The outcome was determined to be driver error each time. This, because the vehicle has no way of recording speed at time of accelerator depression. The acceleration was NOT in proportion to the surprise result, instead a "spurt of speed" rather than the slower anticipated speed required when pulling into the garage or into a parking spot. These 2 episodes occurred after a time of, what could be considered, a normal day of driving, parking, stopping and accelerating at intersections, in parking lots and regular street driving.
The car randomly brakes dangerously hard at overpasses while at highway speed for zero reason while in cruise control mode. This has occurred four times during our brief ownership. I have to imagine these events WILL lead to an accident as the braking is so hard (as if you applied brakes in an emergency) that a driver caught off guard could easily loose control of the vehicle. We have attempted to contact the manufacturer several times, but no one answers calls and their website will not accept inquiries into these highly unsafe incidents to know if there is a problem with our car or software. In fact they hide behind technology so well I do not believe thee is a way to ever talk to a real person or file a written complaint. Please help!
While using adaptive cruise control on 2023 Tesla Model Y we experienced multiple instances of emergency braking (rapid deceleration w/o touching brakes, accelerator steering column, etc.) without any warning during multiple scenarios - dusk, daylight, sunny and cloudy weather. Occurred on both straight and curved sections of highway with no other vehicles in front of vehicle.
When traveling on the highway at cruising speeds of 65mph or higher while in "cruise control" the car will suddenly slam the brakes on. Luckily there has not been any one close to me to cause a rear end collision. It seems to be random but there are times when it happens more often. On a two lane highway or if a car in front of me is slowing down to make a turn. One time a car entered the highway going in my direction from the shoulder and kicked up dust and debris. That seemed to confuse the cruise control and then it finally decided to slam on the brakes.. The only way to correct it was to press the accelerator. Sometimes the braking is severe and other time mild but always unpredictable.
On 30th July 2023 while driving on interstate 8 freeway while using the FULL self driving our vehicle applied auto brake without anyone around. This air rake was so strong that it slowed the vehicle from 75 mph to less than 50 mph in seconds. It scared everybody in the car. We took off the autopilot and applied the regular autopilot and it happened again two more times. Each time there was no vehicles around us and luckily no one was behind us.
Hi, I was on cruise control (not autosteer) on highway and I just applied turn signal and my Model Y suddenly applied brakes and speed was reduced to around 50MPh from 70MPh. We might get into some serious accident if there was a car behind us. Need someone to look into issue please.
What component or system failed or malfunctioned, and is it available for inspection upon request?: I got delivery of my new Model Y and odometer was reading 3 miles, i took the delivery and drove 10 miles and it stuck the steering wheel , "rear motor got disabled alert" and vehicle went to slow speed on freeway all of sudden, i had truck behind me it would ended up very bad for me and family, i had to immediately put emergency signal and stop on road side, i tried to call tesla road safety helpline and they were totally busy and did not receive call. How was your safety or the safety of others put at risk? ; this car "rear motor disabled " twice in middle of freeway , Has the problem been reproduced or confirmed by a dealer or independent service center?: Yes they confirmed but unable to give me more details . Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? : No they kept it secret with less info. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear?: No warnings, just stopped over in middle of freeway . so scary specially to new car. I would like the federal safety agency to inspect all new model Y car which have problems reported please check online and see the percentage of people received this kind of risky issues.
While driving about 75 mph on an expressway using autopilot or just cruise control, the car decelerated to about 40mph within a few seconds. Thankfully there were no other cars behind me. They likely would have crashed into me if so. I believe Tesla calls this problem “phantom braking.” There were no other cars or objects in front of me when this happened. This happened all within 2-3 hours on a road trip in sunny and dry weather on a pristine road. The first time was on “auto pilot.” After that scary experience, I only used cruse control and it happen twice more on the same trip. Again, weather was clear, it was during daylight and there were no other cars or obstacles in front of me when the “phantom breaking” occurred. Tesla said to hit the car icon on the car’s control screen if it happens again. Frankly, I feel it is unsafe to use autopilot or cruise control to do so to try and duplicate the experience to report it for Tesla.
All of a sudden, steering wheel control was lost. Steering wheel was so hard to rotate that it was even difficult to park the car. Also, I was getting lots of pop up messages from tesla vehicle operating system.
I experienced multiple dangerous phantom braking instances on Eastbound I10 between Van Horn and Ozona, Texas when the TACC system was in use. The car is on firmware 2023.20.9. There were no obstructions in the road and no traffic in front of the vehicle when the car suddenly braked going from 80mph to 50mph in a second before I could take control and accelerate. In two instances, cars were behind me creating a dangerous situation both in terms of an unexpected slow down on a barren stretch of interstate and possible road rage if motorists believed I was brake checking. There were no warning messages on the screen and no audible warning sounds. This is a consistent problem with this vehicle and seems to happen regularly on desert interstates or other highways where there are not many trees on bright sunny days. These events seem to happen on stretches of highway in which there may be a loss of cell signal so I wonder if that is a contributing factor. Regardless, Tesla needs to fix this issue as it is unsafe.
The car will sometimes brake hard for no reason, nothing in front of it
While driving on the interstate at 85 mph on a straight flat road, with no other vehicles around, the car suddenly and violently braked. Car was in autopilot beta mode. However, this has happened before while only using cruise control. This happened twice only minutes apart. This issue is typically called phantom braking.
