Experienced dangerous situation while using Speed Control, aka: Cruise Control, with NO vehicles ahead of mine, a totally empty road in New Mexico on I-25, the Tesla Model Y with 2,000 miles on it suddenly braked, dropping the speed over 15mph, then suddenly accelerated, I read this is a known problem and is known as Phantom Braking. It happened several times during the trip, once with a vehicle behind me creating a VERY dangerous situation. I have stopped using this feature until Tesla offers a proven fix for the issue.
2023 Tesla Model Y acceleration complaints
Page 6 of 7: complaints 131 to 160 of 168, newest first, as owners wrote them.
Approximately 5 times while using Adaptive Cruise Control my 2023 Tesla Y will abruptly brake and slow down approximately 10-15 mph even through there are not roadway dangers. It is a startling event every time.
Repetitive phantom braking. Happens quite often. Three time today on the intestate. I had cruise control set at 71mph and without any vehicle or obstacles in the area the car hard breaked from 71 down to 40. I have it on video.
We have had our car for under 3 months and have had repeated episodes (easily 2 to 3 dozen) of extremely rapid braking when the car is in cruise control on the open interstate road when there are no cars ahead of us or any other obstacles that might have triggered the camera sensor. Tried turning off the forward collision avoidance option and the events still happen. Have kept the windshield over the front camera areas clean. It has happened typically during sunny days as we have not usually used the cruise control in the rain. When these events happen there is typical rapid slowing of the vehicle by 20-30 mph within a few seconds. If a car was following close behind us, there would be a high chance of collision. There have been no warning messages or any signs that the vehicle is otherwise malfunctioning. When we contacted Tesla technical assistance, they emailed us a copy of the part of the car manual that says the feature might not function in bad weather, if the camera is not clean, in construction zones, etc. none of which describe the circumstances of when this malfunction happens in the car in broad daylight. They also said whenever it happens to send a bug report which the technicians will look at. They also said it might be fixed with the next update, which of course, it wasn't. Finally, in the same batch of emails, they sent email that said we could report our issue to the federal safety agency which without any other resolution method to the problem, is why I am reporting it here. It seems as if there are many Tesla owners who are reporting this problem online. It may have been less of a problem before Tesla removed the radar feature in the last year and depended solely on their front cameras to make automatic braking decisions for the car. Whatever is happening, it isn't working and makes driving with cruise control scary and dangerous. Thank you for listening. Please help.
I have owned my new Tesla for about a month and it has had a recent software update. Today, I had the cruise control set to 75mph on the freeway and the car very suddenly reset the speed to 50 mph for no apparent reason, making the car rapidly and suddenly slow down. I figured this was just a fluke and later tried to use the cruise control again. This time the cruise control was set to 75 mph on the freeway and the car very suddenly reset the speed to 30 mph for no apparent reason, the car very suddenly hard braked on the freeway. I had to swerve in the other lane so the car behind me did not rear end me. Luckily I did not get into an accident but it was close. This is very dangerous and unacceptable to car safety. I have never experienced anything like this in my life. I have scheduled an appointment to have my new Tesla looked at but I want to notify the government about a serious safety issue with the Model Y 2023 Tesla.
While driving on a relatively straight, 2-lane highway with cruise control set and no autopilot, the car started to brake suddenly and aggressively. This caused the car behind me to almost rear end my car. Luckily I was quick enough to press the accelerator to avoid the accident. This same sudden braking happened a total of 4 times within a 200 mile trip, one of which almost caused an accident.
Car was in autopilot multiple times and sharply applied brakes with nothing in front or obstacles. This is dangerous and almost caused an accident.
A two-month old Tesla model Y encountered phantom braking at least 12 times in 5 days while Autopilot was activated. All incidents happened in a 4000 miles round trip on I-5 in California, I-10 in Arizona, and I-10 in Texas. The vehicle underwent automatic braking without any prior prediction. As a result of these incidents, there was a potential risk of the rear vehicle colliding with my own vehicle, or the potential risk of neck injury. These incidents happened on 05/08/2023, 05/09/2023, 05/19/2023, 05/20/2023, and 05/21/2023.
Driving at 80mph with cruise control on in daylight, car suddenly for no reason braked hard, this occured 2 times hard and several other times enough to alert us while driving and take Cruise Control off by touching brake pedal Car went immidiately from 80mph to 60mph throwing us forward in our seats.
While driving down the freeway on 4/29/2023 my Tesla Model Y slammed the brakes on for seemingly no reason without warning. This incident occurred with auto pilot and auto steering engaged. The day was clear and road was clear.
Phantom breaking when adaptive cruise control is on. Manufacturer refuses to help and promises a software fix is on the way. No way to use cruise control without adaptive cruise control, so no way to use cruise control safely. I was pulled over today after the car decided to brake check a sheriff deputy. Lane departure warning activates for no apparent reason. Does not go away when the feature is disabled. Actively corrects for the non existent lane departure; came inches from crashing several times in 8,000mi. Tesla suggests I use an alternate route because this one is "too rough". It's an interstate. Forward collision warning activates for no apparent reason despite being set to off. Does not actively brake but it does make a startling chime.
While driving down the road in traffic, several errors started appearing on the Tesla screen, and the vehicle lost power brakes and steering, rendering it impossible to drive safely. The complete set of car systems that were disabled all at once was: stability control disabled traction control disabled automatic vehicle hold disabled lane departure avoidance unavailable ABS disabled steering assist reduced (no power steering) regenerative braking features temporarily limited automatic emergency braking disabled The car is only weeks old. We had the car towed to a Tesla repair center, and they said due to a wiring issue, the wheel weight on the right rear wheel was rubbing against the wire connecting the wheel speed sensor, which led to this cascading series of errors. I'm concerned this is a systemic issue with newer Model Ys. There's a QA or manufacturing defect, and Tesla, along with the federal safety agency, needs to investigate this dangerous safety issue.
Tesla abruptly reduced speed by as much as 30 mph while using cruise control in various scenerios. @ lanes highway with oncoming traffic, divided highways with no traffic or obstacles nearby. It happened at least 6 different times while on a 1400 mile trip. There were no warnings issued in any of the occurances. I discontinued using cruise control because of this issue. I have an appointment to take the Tesla in on May 5, 2023 to correct the problem, but after researching this issue, I now know this is an ongoing problem At 2 of the supercharger stations we stopped at, 2 other Tesla drivers asked me if I had this issue, because they were experiencing it also.
This is the problem know in Tesla world as "phantom braking." This happens to me frequently. I am driving on a clear road, no obstacles, and the car will brake hard for no clear reason. At best this is annoying. But there are times when it is extremely dangerous. This happens on highways and interstates at highway speeds. Drivers behind me are forced to brake hard to avoid a rear-end collision.
Automatic emergency braking occurs without cause at high speeds on flat divided Hwy. Happened on multiple trips 5 or more times in a 3 hour drive on 3 different highways in NM. Tesla service has addressed the issue twice. said everything is working properly. Happens when Cruse control + auto steering are active.
every time while driving at highway speed with cruise control enabled the car will decelerate or brake hard without anything in our path of travel for as far as the eye can see. this is a safety issue as the cars behind us may not be able to react fast enough to avoid hitting as our car brakes without cause.
New Tesla Model Y brake failed and accelerated resulted in a serious crash within 2 hrs of taking delivery. I believe it is acceleration functioning and brake due to auto pilot feature. Vehicle will be available for inspection after 4 weeks. After taking delivery of new Tesla Y, we drove to temple. While parking car accelerated and lost control of the vehicle as brakes were not working. It hit the temple wall and when we tried to backup to get the car out of the crashed wall, it got even worse. It reversed in lightning speed and hit another car, run over the bushes and huge palm tree across the street and finally stopped. This terrifying experience caused huge mental trauma, multiple property damage, and financial hardship that we are dealing with right now. Fortunately, there were no injuries. We lost all the trust and confidence in Tesla. We are NOT confident of driving due to huge safety concern. It is a very important safety issue considering the customers at large. Tesla service has not worked on the diagnosis. We tried reaching out Tesla service to investigate the failure. There is no response from them and they keep cancelling the service appointment. On top of it, there is no appointment available in body shop for a month. This incident was reported to police. One observation was made during the incident where Auto pilot beta was displaying on the dash board monitor without invoking any self driving options.
Around 3:54 PM EST, I was traveling on US 1 Route 1 North Bound, and I tried to turn right into Target Complex (4196 US-1, Monmouth Junction, NJ 08852) from Route 1. I slowed down to turn into the complex, and my vehicle had Sudden Unintended Acceleration while I am turning into a parking location. It jumped over the curbs and hit a tree. Airbags got deployed, and the car was damaged badly. Insurance deemed it a total loss. I saved videos from the crash from the USB. I can forward or upload them.
On a multi day drive across the country I had multiple episodes of automatic breaking while on autopilot and using Traffic aware cruise control. In all instances there were no vehicles in either lane ahead of my vehicle. Braking episodes did not result in an accident but made the features essentially unusable.
At highway speed, using the autopilot feature for speed control only, the car applies severe braking when there is nothing obstructing the road or requiring brakes. This has happened dozens of times over the first several thousand miles we have owned the new car. We filed a report with Tesla and they said this is not a problem and is expected behavior. We are concerned this will occur with a vehicle behind us resulting in being rear ended.
on 30th MAR 2023, when my wife drove on to our drive way with gentle speed, car rammed into closed garage door and broke the door and rammed into living room wall with breaking room entry door . there is neither emergency breaking /stop nor collision warning . it damaged wall , garage door and more living room property damage with addition to damage to the car. i am really worried about the safety of the car..
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.
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.
While driving acceleration pedal got loose and fell on the floor or 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 that while at a stop with the brake pedal depressed, the vehicle unintendedly accelerated. The contact stated that no warning lights were illuminated. The contact stated that she rear-ended the vehicle in front as she turned the steering wheel to the left and landed in a ditch. No air bags deployed. The contact stated that she and her front-seat passenger sustained no injuries however the other vehicle driver was seen by the EMTs on the scene. A police report was filed. The vehicle was towed to an authorized Tesla Center and was awaiting diagnosis. The manufacturer was notified of the failure and a case was opened. The contact stated that she was informed by the manufacturer that a diagnosis team was working on the diagnosis. The approximate failure mileage was 473.
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.
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.
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.
I was driving on the George Bush Turnpike on with cruise control set at 80mph. There were few cars on the road an no cars in front of mine. All of a sudden the car went from 80 down to 60 mph and I had to recover manually by pressing the acceleration pedal. The only interesting point is that there were 2 cars accelerating at a higher speed in the next two right lanes that were passing me and didn't cross into my lane. There were no cars within 10-15 car lengths in front of me. Thankfully there were also no cars behind me so I was not rear ended due to the sudden deceleration. I cannot get in to even discuss the issue as Tesla has failed to service the car after moving 5 scheduled appointments in the last month. They now tell me my next appointment is Feb 24. To be fair they are not aware of this specific issue...the appointment was originally for several other issues unrelated to safety.
