general problems of the 2023 Tesla Model Y - part 2

The cruise control has been braking for no apparent reason, putting myself and the people behind me at risk. It also tried to stop at multiple green lights rather than continue driving. The his also outs me, my passengers and people behind me at risk. There were no warnings about this behavior. I have the latest update and will also contact Tesla about the issue.

Car slams the brakes while on autopilot with no obstacles on the highway. Car speed reduced at least 20 miles for no reason. Weather was clear.

While driving at hwy speeds in the #2 lane the #1 lane to my left was closed with construction cones. I was in the lane with cruise control activated and driving at approx 70 mph with flow of traffic. I had been in this lane for a few miles when all of a sudden the car rapidly decelerated approx 10-15 mph in a very short distance. I took control of the acceleration by quickly taping my brakes. Luckily there was no one behind me, as it could have created an accident risk. My only guess is the car interpreted the line of cones as a hazard even though they were not in my lane.

I was driving on a 2 lane road with cruise control engaged (not full auto pilot). As I approached an intersection with an oncoming semi-truck, the vehicle slammed on the emergency braking system slowing from 60 mph to 45 mph in about 30 feet. I think it is called phantom braking. I was driving into the sun at 2:45pm.

During highway driving, on two separate occasions that were two days apart, while using cruise control set to ~72mph the vehicle suddenly tried to stop. It quickly decelerated by ~25mph before I intervened by pressing the accelerator. There were no obstacles in the road and on the second instance there weren't any other vehicles in site (was in remote northern nh/vt). Had someone been driving behind me we very well could have been rear ended. I was driving with by wife and three kids and did not feel safe.

I am writing to express my dissatisfaction with my new Tesla Model Y rwd, which I received on December 3, 2023. I have encountered two major issues with the vehicle and the customer service. First, I was promised by Tesla representatives that I would receive six months of free supercharging after delivery, as part of a referral program. However, this offer has not been activated yet. When I contacted Tesla, one of the supervisors told me that I was not eligible for this offer, because I placed my order on September 23, before the program started. This is unacceptable, as I was assured multiple times by Tesla agents that they would honor the offer and match it before delivery. I also offered to take back my self-driving capability which is available to me for free for the first 3 months. Second, I have experienced serious problems with the auto-pilot feature of the vehicle. I have used it four times briefly in the last month, and every time the car slowed down significantly when it was supposed to cruise at 50 mph. Twice, I had to avoid rear collisions by pressing the accelerator or the brakes. I reported these incidents to Tesla through the app, but I have not received any response or explanation. The most alarming event occurred on December 26, when I was with my family on a return trip from ikea in woodbridge, va. The weather was bad and the Tesla suddenly stopped on the road. I suspect that the front camera falsely detected an obstacle and caused the car to brake abruptly. These issues are not only frustrating, but also dangerous and potentially life-threatening. I am very disappointed with the quality and performance of the Tesla Model Y, as well as the lack of customer support and accountability. I request that Tesla either provide me with a satisfactory solution or compensate me for the inconvenience and risk that I have endured. I have a legal background and I am aware of my rights and remedies under the lemon law and other consumer protection laws.

What component or system failed or malfunctioned, and is it available for inspection upon request? slowed down entering a driveway when car sped up on its own , forward collision warning/emergency automatic breaking did not warn or do any breaking. No sound or warning on the computer screen. I brake but the car still hit the post. I do not know what speed it accelerated to. I am not sure if autopilot kicked in but the car accelerated when I have already released the accelerator. How was your safety or the safety of others put at risk? yes - injuries sustained. Has the problem been reproduced or confirmed by a dealer or independent service center? when calling Tesla on Dec 23, 2023 - was told by the rep that ticket has to be filed but I was disconnected and I was not able to get through the lines. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? yes - car was totalled. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? I never saw any warning lamps come on as I always driven with distance. The camera was worked was worked on due to the wiper going on even when not raining on October 24 but the fix did not work. Once at the emergency room, trying to call Tesla or texting the no that responds when buying the car no longer accepting my text. The promise that when we get car accident, Tesla will call - no phone calls. All I received was text alert car suffered failure and was deactivated. I was in pain and not able to follow up and try to do report and look at pictures. . Today I just received a letter dated 2/8/2024 about recall no 23v-838 in the mail. But the car is gone. . . The software version it had is 2023. 27. 7. The tech guy came here to the house on oct 25, 2023 and checked everything.

The car was behaving like in “rolling” mode even though it was set to “hold” mode. The modes refer to the stopping modes. I have reported the incident to Tesla and it’s been in the shop for over 1 week.

I have had multiple phantom breaking on the highway in when use autopilot in my 2023 telsa Model Y. I scared of using the autopilot now cause of an accident on the highway.

I was driving north on I-5 in northern California when the car braked twice for no apparent reason. I was using the traffic aware cruise control. The first time the car was on a slight curve to the left and there was traffic in the right lane. About two hours later I was on a straightaway with no nearby traffic.

Phantom braking occurred while traveling eastbound from austin to houston on us 290. Vehicle was traveling 76mph and slowed to quickly to 55 mph for no reason. There was a highway overpass about 75 yards away which may have triggered it, but no vehicles around us. Scared my wife and kids!!!.

Respected authorities, we bought Tesla Model Y in may of 2023 with our hard earned money, and next day or so we noticed a big paint mark on this brand new car. . Upon following up few times, Tesla agreed to repair this but they damaged further and after repeated visits, they agreed to replace the seat cover. . However, while replacing the cover, they damaged the side door coverings. Again after lot of follow up they agreed to replace that part as well. So, we thought we are happy but later we had to face very scary situations with this faulty car. The steering car completed locked while driving and had to face very dangerous situation. We are fortunate that the traffic was low in the street road, and if it was in highways, then it could have been fatal. Earlier, when we are reversing the vehicle in the garage the vehicle didn't turn well enough and the driver side mirror was hit the garage siding, and earlier to that when we are turning the car to the neighborhood the tire got touched to side walkway and threading was damaged. We strongly believe these could be the result of the steering wheel on and off locking in second which we are not sure at that time. As Model Y is new to us, we are not sure how that drives but now understand the issues clearly. We humbly reported all the above to Tesla service, and they wanted to do steering wheel issue only and charge the other two. . . The important thing here is we were saved earlier due to the steering wheel issue but not sure if I we feel safe driving this car again. Kindly help us get some justice, and it would be appreciated if they take their car back and return our money in full. Thanks sridevi ghatta .

I experienced a sudden unintended acceleration while parking the car in my home garage, something I have done thousands of times with no difficulty. I had this brand new car for a 12 days before it smashed through my garage wall. My garage is a fairly tight fit, so as I always do, I partially entered the garage and stopped to make sure that the side mirrors were going to clear the garage entrance. Then, I lifted my foot off the brake in order to start moving forwards again, at which time the car suddenly accelerated like crazy through the remaining 12 ft of space, smashing the cabinetry through the rear wall of the garage. The car, my garage, and laundry room were severely damaged. I complained to Tesla about this vehicle problem, but they just say there are no problems with the car, and it must be the driver’s fault. They are implying that I floored the accelerator, which is nonsense. I have been driving for more than 40 years, and I do not floor the accelerator while parking in my home garage. This type of sudden unintended acceleration is a danger to public safety, and this matter has to be thoroughly investigated, and a solution has to be found to fix the problem.

I bought Tesla and Tesla insurance which monitors driving of driver to provide safety score to driver. The safety score enables monthly premiums of Tesla insurance. My complaint is related to safety score which provides financial incentives to drivers to not apply break. As part of safety score provided to drivers in Tesla app(screen shot attached), one of the factors used is hard breaking to penalize drivers when break is applied, forcing the driver to use regenerative breaking instead of applying break. I have observed, even when I mildly apply break the safety score is impacted. The second factor in safety score that seems unreasonable is driving after 10pm. My daughter worked late shift and would return home after 10pm. Why is this even allowed as most of the emergency workers and many others work late hours. I have also observed safety score change from 99 to 98 when the car is parked overnight, even when I am not driving.

I was driving November 6, 2023 at about 10:30 in the morning at approximately 25 to 30 mph on a neighborhood road when my car accelerated on me without me applying extra pressure. I was caught off guard and thought it must’ve been an anomaly. We have owned the car since August. But then on my way home, about 1 o’clock, I was again on the neighborhood street doing 25 to 30 mph and the car obviously accelerated on me so that I applied the brakes. My husband was in the car with me and really noticed it surging the second time. At the time, it concerned me so I looked on the internet and saw that other people have been complaining of a similar issue. I want this on record because I know I did not apply pressure to that pedal. We have scheduled a service with Tesla Friday.

I was driving on the freeway at approximately 67 mph using the advanced cruise control. There was no car immediately in front of me or directly beside me. All of a sudden, the car decelerated quickly, as if it slammed on the brakes. I was able to react quickly and override the deceleration, but had there been a car directly behind me, I very likely would have been rear-ended. It all happened so fast that I didn't stop to get all of the detail, but I'm guessing I dropped down to about 50 mph before being able to respond and override the breaking. It was terrifying, as I didn't know if I could override it at first. I later read other complaints about "phantom breaking" and realized there is a pervasive problem with the Tesla.

While traveling on an open highway with no obstructions, the vehicle applied the brakes very hard causing all passengers to slide forward in their seats activating the seat belt locks. All cargo became airborne and flew forward. Had a car been following, it is highly likely that we would have been rear ended.

Unintended acceleration in a Tesla.

On October 24, between 8:45 and 9:05 am, I was traveling on the highway with cruise control on and the car suddenly braked going from 75 to 30 rapidly. It was only me pressing the accelerator that kept it from coming to a complete stop. Fortunately, there was no one close behind. There wasn’t any traffic around me. I was passing an exit. I reported this to Tesla and they remotely investigated but said that the related cruise software and hardware was operating normally. This is extremely dangerous! I’ve checked Tesla forums and this is a known problem that they don’t seem willing to address.

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.

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.

While using cruise control on a recent road trip, the car braked suddenly for no apparent reason. This happened 7 times over a time frame of 11 days of driving. Each time it occured while traveling on a freeway (2 lanes each direction), large median, very light to no traffic, during the day, the car slammed on the brakes, without warning while traveling the speed limit (up to 75 mph). The first time it occured, I almost came to a stop before recovering and accelerating to normal speed. This happened on oct 15. The second time it happened, was on oct 16. After the 2nd time, I would not use cruise control unless there was no other traffic. There were four times of phantom braking on oct 30 alone. I have not yet submitted a service request to the manufacturer.

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 NHTSA 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.

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.

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 read this news today and something very similar has happened to me on autopilot. . Read more...

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.

On September 23rd our vehicles cruise control stopped working. We submitted a service request to Tesla and they scheduled a service appt for October 16th. They later cancelled this appt saying that it is a known firmware issue that would be corrected in a future, undetermined, firmware update. On November 16th we took the car to a Tesla service center and they confirmed it is a firmware issue, but could not correct it. We have now been without the adaptive cruise control function on our car for over 2 months with no idea when or if this problem will be fixed.

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.

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, sidney beitz.

Abrupt, rapid, unannounced deceleration with no apparent cause. Has happened multiple times.

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 NHTSA to ensure my Tesla Model Y is defect free. I just bought couple of months ago. I would like to request NHTSA 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 NHTSA. 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 NHTSA 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 NHTSA to investigate this issue swiftly. Given the popularity of this model, many drivers could be at risk.
