Vehicle Speed Control Problems of Tesla Model Y - part 2

While using adaptive cruise control the vehicle regularly decelerates for no reason and without warning "phantom braking". I experience this about once a week, but experienced it multiple times on a longer drive this weekend. The unexplained abrupt braking could result in being rear-ended by another vehicle.

On [xxx], traveling westbound from [xxx] on [xxx] using adaptive cruise control. Pick-up truck rapidly pulled up behind and cruise control shut off, stated "unavailable" and Tesla started to brake. . . Manually overrode. Travelled another 1/4 mile and reengaged cruise control after pulling away from following pickup. Pickup caught up and cruise control shut off again. At 4-way stop on [xxx] , rechecked system and then headed for [xxx] on adaptive cruise control. Pickup came up again and cruise control shut off. At next intersection I turned right and pickup turned left. . . Had "electronics" sign on side of truck. Not able to get full name. Question: is there electronic systems "out there" that can take control of Tesla adaptive cruise controls? I tried to pass this on to Tesla, but wouldn't or couldn't take the above message.

The contact owns a 2024 Tesla Model Y. The contact stated that while driving approximately 15 mph the vehicle suddenly experienced unintended acceleration causing the driver to loose control of the steering and crash into a second vehicle. During the crash the frontend of the vehicle was severely damaged but the air bag did not deploy. The contact sustained a right hand injury that did not require medical treatment. Three occupants from the second vehicle sustained undisclosed injuries and were transported to the hospital. A police report was taken at the scene and the vehicle was towed away. The cause of the failure was not yet determined. The manufacturer and local dealer were notified of the failure. The failure mileage was 7,608.

2023 Tesla Model Y has frequent phantom braking issues when using cruise control. Let me clarify I am not using any sort of auto-pilot or self driving options. I am simply using cruise control. The incidents that cause many braking issues are unjustified to the point I have no idea what the Tesla may have recognized to make it slam on brakes. Very dangerous.

I was parking the Tesla Model Y at very low speed, when there was a sudden unintended acceleration. The car banged against the wall of a building and was severely damaged. My family - wife and two children were in the car.

I have reported this same issue twice before. When on cruise control, the car brakes unexpectedly. My 2nd and most recent report was on June 2, 2024: ". . . I had already disabled "apply brakes when regenerative braking is limited" under dynamics on the screen. (see photo) he showed on the screen, under autopilot, that I could disable automatic emergency braking, which I did. I was concerned that this warning pops "the vehicle will not automatically apply the brakes even when a collision is detected" (see photo) but he suggested I try it to see if it would solve the cruise-control braking. I was hopeful, and disabled it, knowing that it might take a while to know if that solved the problem. I drove the 30 miles home on the frontage road instead of the interstate, and when there were no other cars around, I set cruise control at 50 mph, the speed limit. I came to a series of small hills in the road, and was reminded of the first time the automatic braking happened, on a 60 mph road with longer amplitude hills of greater height. Amazingly, it happened again! pretty significant braking and slowed me to 25. This time I waited it out to see if it would resume the cruise control at 50. It did not. I have since restored the automatic emergency braking as that seems important for a crash situation. I have restored the "apply brakes when regenerative braking is limited" since that obviously was not the problem either. " I did not use cruise control again until August 23, when I happened to be returning home from silver city to las cruces and was on the same highway, 180, where the problem first occurred. It is a 2-lane road and often there is no traffic, so I felt safe trying cruise control again. I set it at 55, the speed limit, and after only a few miles the car braked again. I do not use cruise control anymore, and was dismayed to find that Tesla is again offering a free trial of autodrive! this is a huge safety issue!.

Multiple, random occurrences of hard braking at highway speeds when there was no object or obstruction ahead. In the 2-1/2 years we’ve owned the car this has happened on two lane and multiple lane highways, generally at speeds over 50 mph. Also, the windshield wipers randomly deploy even when turned completely off. They generally work when it’s raining but the delay function is also randomly not in sync with the settings or actual rainfall.

Driving north on [xxx] just north of red ond oregon on a 2 lane section at sunrise with traffic aware cruise control set the Tesla braked aggressively when a semi approached in the oncoming lane. Neither vehicle crossed the center line but the crash alarm blared and the car braked almost causing a rear ending accident. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

While driving straight on a 2 lane divided highway, the traffic assisted cruise control decided it needed to slow itself down significantly to 15 mph under the speed limit (posted speed limit was 65 mph). There were no vehicles in front, behind, or beside my vehicle. The breaking occurred when it came across a line break where cars from the opposite side of track could turn left onto a service highway but no one was in that divide nor in the turn lane. There was no warning or any obvious indication that the vehicle should harshly slow down for any safety reason, where in fact is there was a vehicle behind me, it could cause a crash. I made a request for Tesla to repair the vehicle, but in my attached photos, you can see that they admit to the issue being software related and insisting that it is an unrepairable problem until a software update can be issued.

The vehicle was under full self-driving mode and approaching a shopping center. There was a crossroad with signs on the corner. The vehicle was supposed to turn left but kept slowly approaching the signs on the corner. I was ready to step on the brake to stop the full self-driving mode while expecting the vehicle to turn left or step on the brake. Instead, the vehicle accelerated toward the signs, so I had to steer the wheel to the left and apply the brake immediately. The vehicle jumped a bit as it ran over the corner of the crossroad and stopped after about 10 feet. I was fortunate because I took action immediately, avoiding hitting other people or property. However, human reactions seem not to be quick enough to prevent some accidents as in this case. During this incident, the right corner of the front bumper of the vehicle hit the signs, and the top right corner of the vehicle (right above the front window) was also slightly damaged.

I was on [xxx] heading towards chicago and following the traffic. I started changing the line to pass the vehicle in front of me and suddenly my Tesla completely lost control and started drifting to the sides. I released the accelerator right away but it made it even worse. It seems that acceleration continues to happen that’s what made car to drift. Eventually car slowed down and I was able to make it to my line. I don’t understand why line assistance didn’t work to keep the vehicle stable, why after releasing accelerator the vehicle continued to gain the speed. It was sunny day and dry road. No foreign objects on the highway. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

When driving home and try to make a left turn, the steering doesn't work and car suddenly speed up even though try to brake, the whole car is out of control, and the car hit my neighbor, and it's extremely dangerous! thank god that no one is hurt. Police came and did a report but didn't say anything about Tesla. After that, I checked the alert history, nothing special, the only alert is remind me that window cleaner is running low. I tried to contact Tesla but failed, no one answer the phone call, no where to report. Everything is too bad.

The contact owns a 2023 Tesla Model Y. The contact stated while driving 35 mph, the vehicle misread the route 10 road sign for the speed limit sign and the vehicle decelerated to 10 mph. There were no warning lights illuminated. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 9,000.

We were about the park in the marked parking lane and the vehicle unintedly accellerated, the brakes did not work and we saw message "automatic emergency brake not available" and air bags not available. We tried to control the vehicle to avaoid crashing into the porch of the infront apartment and steared the speeding vehicle and the vehicle hit the pillar of the aparement and finally came to halt few meters away in the parking lot as the front right wheel broke. 1. The adas automatic emergency breaking seems failed 2. Forward collission warning seems not working 3. The safety of the driver and the passenger were at risk while the collission happened 4. I am not sure if the similar incidents happened or can be reproduced by the dealer/manufacturer. 5. Vehicle components inspected by the Tesla collission center but no software logs inspected and they said that they cannot get the device crash/event logs. 6. At the incident/while the incident was underway we saw few message that displayed "automatic emergency brake is not avaiilable" and "air bags are not available".

The contact owned a 2023 Tesla Model Y. The contact stated that while driving at 30mph, the vehicle independently sped up and took over the contact was unable to control the vehicle. The vehicle struck 2 parked cars, and 2 street signs. No warning lights were illuminated. No injuries were sustained. A police report was filed. The vehicle was towed. The insurance company deemed the vehicle totaled. The manufacturer was made aware of the failure, and a case was opened. The failure mileage was approximately 12,000.

We were trying to park the car in our garage when the car suddenly sped up. And hit our the fence . I released the pedal but it kept driving until I hit the brake. Air bag did not deploy. The car?s front was smashed. Our fence is also badly damaged. I have asked Tesla to investigate if it was because of the autopilot taking over but have not received a response from them yet after more than a week.

Phantom braking occurred when the adaptive cruise was engaged when a truck entered the road from the right side. The car abruptly slowed when the truck crossed my lane although there was no eminent danger. The car behind us nearly collided with us due to the sudden braking incident. This is the third sudden braking incident; however, the others were related to a bridge or overpass.

Was traveling along the I-5 south about 5 miles north of the 99 interchange. Vehicle was in traffic awareness cruise control when it suddenly applied the brakes. Vehicle did not sound any warnings. Vehicle did not display any warnings. Vehicle made no attempt to warn driver of a braking event. Vehicle traffic awareness cruise control was set to 79 or 78 mph in a 70 mile per hour zone. I was able to push the accelerator pedal to regain speed but had already dropped to about 65 mph. Vehicle did not pass under a shaded section ( I. E. No bridge or trees or big rigs) there was change in color of the road top. My foot was resting just in front of the accelerator pedal. Fortunately for us, there was no vehicles directly behind us. This incident is the 3 of this kind in this vehicle. This has me spooked to use any of the convenance software. I already do not like using the autopilot feature because of it erratic behavior. It feels very unsafe and unpredictable. We are unable to predict when this car will act on its own and feel it will cause us harm one day with actions like this. We are glad that no one was following us closely because they might have hit us. We are also upset that the vehicle never stated why it braked suddenly.

Tesla removed the ability to use only cruise control, with adaptive following distance, and have forced the only option to now use full self driving instead (with a recent soft-ware update). I do not feel safe using full self driving (even supervised) and believe Tesla is being unsafe forcing full self driving use. We used to be able to just use cruise control-with adaptive following distance-a driving option in all other recent cars!!! , but cannot do that now in Tesla? why would a company take away what I consider to be a safer option?? this is not an improvement (but a forced help-Tesla-improve-it’s-unsafe-full self-driving-software!).

The main screen on my Tesla Model Y flickers while driving, as well as charging. I have a video of it happening, if you slow the video down it completely shuts the screen down for a millisecond and then turns back on. I have sent this video to Tesla, as well as Tesla technicians has confirmed the issue happening when they had the vehicle. I have had the vehicle into Tesla 3 separate times for service, they don't know how to fix the issue and keep telling me to wait. I have been dealing with this issue since January 2024 and am tired of waiting and putting my safety at risk. I feel that I have been more than patient with them and now I feel that they are now blowing me off. They don't feel that it is a safety concern even considering that the display screen went out while driving 70 mph, for 13 miles and I couldn't get it to turn back on.  aditionally the side cameras on the vehicle intermittently go out. There is no warnings or symptoms prior to it happening it just happens. I have 29 times documented of it happening to me. I have requested a buyback which was denied as well as a loaner from Tesla until they can fix the issue, yet they denied that as well. It seems that Tesla does not care about the safety of me and I want this issue to be investigated. I have the video of the screen flickering reach out to me to get it since I cant post it in the place below.

I was driving down the highway with my wife and baby at about 65 mph. I was using regular cruise control with no one in front of me when all of a sudden, the car braked extremely hard. Luckily, the car behind me was far enough back to switch lanes and pass me. If it was closer, this could have resulted in a highway accident. The car stopped braking maybe around 30 or 40 mph. I may have it recorded in the Tesla camera system since I pressed the save button approx 4 min after it happened. I also scheduled a service call with Tesla that will hopefully happen on may 7th.

My wife and I purchased a Model Y 2024 just a few weeks ago. We have had multiple experiences when using cruise control where the car inexplicably slows down rapidly when there are no vehicles in front of us decelerating.

I am reaching out on behalf of my wife who met with accident on 3/24/2024. She was driving Tesla y model and this accident occurred due to system failure of vehicle , brakes and steering wheel get locked and she was not able to do anything and car hit the couple of trees on other side of parking lot . She was not using autopilot feature and it vehicle didn't stop after applying the brake instead of stopping , its get accelerated and steering was also locked.

I was performing a 3-point turn on a residential street. While reversing during the turn the automatic emergency braking enabled and slammed on the brakes, bringing the car to a complete halt instantly. This caused my head to hit the headrest with enough force that I have headaches and brain fog the next day, indicating a concussion. I was 10 feet from the nearest parked vehicle when reversing; the aeb kicked in erroneously. This is not the first time that Tesla's aeb has erroneously and dangerously engaged while I was driving.

Car was being driven into a car wash. Driver went to put car into neutral and car lurched forward and crashed into car in front of it without gas pedal being engaged. Vehicle has not been inspected by manufacturer or others. No warning lamps or other messages. May have been related to recently installed full self driving software that was automatically installed but was not requested by vehicle owner. Vehicle owner did not intend to engage any sort of self driving or automatic acceleration systems.

While driving to work, using fsd, the autopilot steered me into the path of an overtaking vehicle moving at about 20 mph faster than my vehicle. By quickly taking over steering and speed control, I was able to avoid a collision. A couple miles further down the road, the car could not decide on which exit lane to use, and weaved between two possibilities, probably alarming and angering drivers behind me. Again, I had to take over control. Taking over speed and steering control was necessary two more times in my 25 minute trip, most of it on well-marked multi-lane highways. Of the four incidents, only one would have resulted in a serious high speed collision, had I not taken over very quickly. Having coached robotics competitions, and piloted aircraft with autopilot, it is my opinion that the fsd (supervised) software is at alpha stage in development (not yet up to beta stage, at which it could be safely released only to select skilled drivers, with suitable disclaimers and warnings) . At delivery, no introduction to the car's controls is provided, so customers are on their own regarding finding out, by trial and error and the occasional potentially lethal collision, how to safely drive the vehicle with fsd engaged. The manufacturer should be required to instruct all customers on the very high level of vigilance required to operate with fsd engaged.

Tesla has failed to provide a software update to address both recalls, and has made it impossible for me to get support to have this rectified. They cancelled a service appointment I made and are no longer responding to my inquiries.

While using autopilot or beta self-driving - when a minimum speed limit sign is detected on I-75 in georgia, the system usually reduces to the speed of the vehicle to posted minimum speed (40 miles an hour) instead of maintaining current speed limit.

Car warned that drivability - acceleration and top speed reduced/performance may be restored on next drive but gave no opportunity for me to pull over safely. Felt like someone pulled the e-brake during regular driving speeds and prevented me from safely slowing down, steering or maneuvering the vehicle into a safe spot. This occurred during a rainy night with my wife and 3 daughters in the vehicle who were terrified and still afraid to drive in the vehicle. Tesla replaced the front drive inverter and about a month later the same issue happened again on a busy road around 1pm in the middle of traffic and this time the rear drive inverter had to be replaced. Myself nor my family have felt safe in the vehicle but feel stuck with it.

During a 2,300 miles recent trip in texas, the vast majority of the speed limit signs were not seen by my 2023 Tesla Model Y autosteer/autopilot (not fsd). This created issues with the autopilot/autosteer as it was not usable in several instances and can create safety issues like distractions, etc. . . I had the latest software revision. The key point is that this is not happening at all in colorado where I live. Tesla support responded that I needed my cameras recalibrated which is a totally illogical response as it is not happening in CO.

You have no doubt heard the news that Tesla has deployed full self driving to all its vehicles as a "free trial. " my Tesla received this update in the past few days. Last night I was driving on an expressway and engaged what has up until now been traffic-aware cruise control by pressing down one time on the right stalk. I expected regular cruise control but the car started steering for me. Tesla has changed the default behavior of the cruise control activation (one single downward press on the stalk) to instead activate autopilot. My attempt to regain control caused me to jerk the wheel side to side in a way that could have led to an accident had I been in heavier traffic. This was unexpected behavior from the vehicle and I find it unacceptable that Tesla has changed a default function in this manner. I had to hunt around on the screen to find the setting to change the behavior back to regular traffic aware cruise control from one downward press. Furthermore, on the same 20 mile trip I had three phantom braking incidents while the car was on traffic aware cruise control mode. This is more than typical and these events can be dangerous if they happen in traffic. Tesla should not be allowed to deploy changes, especially without notice, that modify basic functionality of a car in motion from what the driver has become accustomed to.

This car does not have full self driving, and I do not use auto steer. I experience multiple phantom braking events every time I use the "traffic aware cruise control. " sometimes I can see that the cruise control set speed has been reduced from the speed I set, and I have to cancel and reset it to resume the original speed. Sometimes the cruise control set speed is unchanged, and pushing the accelerator will cause the car to resume the set speed. Yesterday I drove 320 miles and had about 6 of these events. I'm concerned about these events causing an accident from the sudden speed reduction, or getting into a road rage situation because the person behind me thinks I am brake-checking them. Internet research indicates that these complaints are very common during the past few years. If Tesla can't - or doesn't want to - solve the problem, they should at least allow us to choose basic cruise control to avoid this problem. Adaptive cruise control would be more reliable with radar, but Tesla is doing everything it can to make the cars cheaper, and radar was eliminated. Personally, I think trying to do everything with cameras is a fatally flawed approach - especially considering cars travel at night and in varied weather and lighting conditions.

I want to report what I think is a very dangerous issue with my Tesla Model Y. We have experienced numerous times that the car brakes without warning. I have talked to Tesla about this "phantom braking", and they say it is "normal". The traffic-aware cruise control cannot be disabled to create a normal manual cruise control. I gave them a hypothetical situation where this could be life-threatening, but they dismissed it. Two weeks later, that very scenario happened, thankfully not ending in tragedy. I was driving at 65 mph on a wide, two lane paved highway (near dove creek, CO). A car going in the opposite direction was stopped on the shoulder on the other side of the highway. A large semi truck, also going in the opposite direction, pulled into my lane to pass the parked car on the side of the road. I saw what was happening, let off the accelerator, and steered over onto the paved shoulder (wide shoulder) to avoid the oncoming truck. My car's traffic-aware cruise control, using the car's cameras, interpreted the situation as an apparent collision danger and automatically braked hard. In this situation there was a large pickup doing what most pickup drivers do. . . . Tailgating close behind me to get me to drive faster. Neither the driver of the pickup, nor me, were expecting my car to brake hard, as we had all assessed the situation correctly as not being dangerous. I responded as quickly as I could by pushing on the accelerator to cancel the cruise control, but the pickup almost rear ended me. At that speed, it could easily have turned into a fatal accident. Tesla says I can't disable the cameras, so I just don't use the cruise control now. I was told you can disable the "traffic-aware" part of cruise control on older model Teslas, but not 2023 and newer. Often the phantom braking occurs with no apparent reason (although the car's cameras and computer would probably disagree). Do many people have to be killed to take a safety hazard seriously?.

Vehicle: Tesla Model Y blue purchased in oct’ 23 Tesla setting: regenerative braking (single pedal driving) issue: brake pedal/acceleration pedal malfunction I was pulling my car out from the parking lot to pick up my mom, from the hospital entrance. I just turned right and had to take an immediate left to leave out of the parking lot. The Tesla was driving at approximately 5 miles an hour at that point. I lifted my foot from the gas pedal for the car to stop with its regenerative braking. However, instead of coming to a stop, the Tesla started rapidly accelerating, with my foot not even on the pedal. When I slammed the brakes, the car was unresponsive and continued accelerating. I started honking madly to warn people that I had no control over the car I was driving. The vehicle continued accelerating over 100-150 meters in 4-5 seconds and banged a parked car (Lexus SUV) at the end of the parking lot. It continued accelerating while pushing Lexus over the curb, destroying road sign poles and landscaping shrubs; crossing the street, and the middle curb. At the end of the street was a tree and a ditch. Lexus couldn’t move any further and Tesla stopped. All airbags deployed. One of the emergency response detection systems called 911 immediately. The first thing the police asked me was if I pressed the emergency brake. I said the car doesn’t have one. I can’t even turn off the vehicle while it is moving. The parking button takes care of it. I used to love my Tesla but I can’t trust it anymore. What I want from them at this time investigate all the incidents thoroughly instead of blaming these as a user error. A) think about adding the redundancy system. Something mechanical where the driver reacts within a couple of seconds. Software bugs are hard and sometimes it is impossible to find the root cause. Logs may not contain everything that you need to debug the problem. Consider it as a p0 issue. B) compensate for the damage and property loss.
