general problems of the 2023 Tesla Model Y - part 2

Traveling on an interstate highway when the car suddenly decelerated. Cruise control was on at the time. Sudden deceleration with cars following made it quite dangerous. We could have been struck from behind. This happened two times on the same trip.

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 eastbound on interstate 8 with adaptive cruise control engaged and my Tesla suddenly stoppeg in the freeway. No one was behind me but it was frightening. 0930 hours.

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!!!.

During our road trip from northern virginia to norman, oklahoma, between 18-29 November 2023, the issue called "phantom braking" -- in which the Tesla Model Y suddenly and inexplicably engages the brake during a highway driving -- occurred to us four times.

The contact owns a 2023 Tesla Model Y. The contact stated that while his grand-son was driving 40 mph with his friend in the front passenger's seat, he depressed the brake pedal as he was approaching a stopped occupied vehicle. A light indicating that the brakes were engaged illuminated, but the vehicle failed to respond. Additionally, the automatic emergency braking system failed to engage, and the vehicle crashed into the rear of the vehicle in front of him. The air bags deployed. The contact's grand-son and his friend were able to exit the vehicle. The vehicle then turned off and locked, which rendered the vehicle unnoticeable by oncoming drivers. Another driver who noticed the incident parked behind the vehicle and activated the hazards lights to prevent other drivers from crashing into the vehicle. The contact's grand-son sustained a burn on the right hand from the driver's side airbag deployment. The friend and the other driver did not sustain any injuries. A police report was filed. The contact's grand-son received first aid assistance from the ambulance. The vehicle was towed to a Tesla collision center, who denied assistance. The vehicle was then towed to a collision center that was certified to work on Tesla vehicles. The manufacturer was not notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 8,000.

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.

Tesla Model Y delivered six weeks ago, I engaged the "auto pilot" for the first time on my morning commute and it worked well for a few moments. Suddenly and without warning the vehicle applied full braking force from highway speed, so hard that it glazed the rotors. This happened on eb I-10 jwo I-15, an extremely busy interchange. With possibly divine intervention I was able to retake control of the vehicle, shut down the auto pilot and I swiftly returned the vehicle to speed, needing only a restroom on an emergency basis. Relevant factors could include low incident angle of the sun at dawn and being in a construction zone with lane markers not thoroughly scrubbed off.

I was driving my 2023 Tesla Model Y on I-680 south on Nov 8 2023. The car was on adaptive cruise control. I was driving within the speed limit. The truck infront of me abruptly stopped as there was another collision in the lane I was on. I applied brakes but the car did not stop on time, and I rear ended the truck. I have received the vehicle data report from Tesla. Attached the report for you reference. I believe the adaptive cruise control did not slow down as it should have and when I manually applied break, the vehicle did not stop.

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.

I was driving my 2023 Tesla Model Y northbound on interstate 69 in indiana near the 219 mile marker. The time was around 9:30 p. M. My speed was approximately 70 mph. I was using what Tesla calls "traffic-aware cruise control". All of a sudden and with warning, my vehicle braked extremely hard, slowing me down very fast. Luckily no one was behind me. I had no idea what was happening and looked all around for danger. After a few seconds, I accelerated and continued on. This phantom braking is very concerning to me. Had someone been behind me a horrible crash would have occurred.

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.

The process of the car losing control around 10:50am to 11:55am: we were driving on woodgate road and were making a u-turn. The car lost control just after the u-turn. The steering wheel spun and failed. The car sped up and the brakes did not work. The car hit the curb and the left tire burst. It went straight over. It was about 3 meters from the sidewalk to the hillside covered with weeds, and it was impossible to stop because the hillside was too steep.

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.

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. ”.

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.

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.

While driving with autopilot/cruise control, the car started braking heavily with no obvious obstruction on the road. This happened 5 times over 2 days of long distance driving.

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.

Tesla Model Y emergency braking applied on a freeway while driving with enhanced auto pilot putting me and my family at high risk when there was no emergency whatsoever. My lane and the lanes either side of me were free and there was no traffic.

Phantom braking happening regularly when auto driving cruise enabled on highways w no oncoming traffic.

The incident occurred because the car in front of me made a sudden stop (there was a 3-car accident ahead of the car in front of me). In response to the sudden stop I hit the brakes hard on my car but my car failed to completely; it kept moving forward until I hit the car in front of me. I was not tailgating the car in front of me and had plenty of room to stop as I braked. Video recording from the Tesla showed the sufficient distance between my car and the car in front of me. I re-recorded using my phone, I can upload it for your review but the size is about 30mb and in . Mov format.

Our Tesla seems to be experiencing regular phantom braking events. We just had an event today while traveling on the freeway. Our Tesla unexpectedly applied the brakes without warning as if it was trying to avoid a collision. No objects were in sight. Our cruise control was active and we don’t have autopilot.

I was driving from austin to houston on 5-Sep-2023 when the car stop from 70mph to zero w/no reason and nothing in front of us; this phantom stop event is real - my daughter and wife were very scared and made me not use the adaptative cruise control for the rest of the trip. I don't have paid for fsd, I was very upset because was the start of the trip and I did not use the car for 2+ hours trip since.

On August 28, 2023, driving back from golf at tijeras creek, the vehicle noted several faults: cruise control disabled, autopilot disabled, parking brake disabled, and others. We parked in newport beach and the vehicle failed to move—appears the parking brake locked up. The vehicle was taken to Tesla for repair; the vehicle had 4,423 miles on the odometer when it was taken to Tesla for repair. The technician states that they identified the brake fault, removed and replaced the right brake caliper. Its disabled the vehicle from safe operation. September 21, 2023, the vehicle was driven locally 23 miles and the condition returned. This time the vehicle was in a shopping mall and the parking brake would not release, disabling the vehicle. Screen shots of the fault codes were taken to preserve the evidence. Eventually, the operator was able to shimmy the vehicle forward and return to the house. On October 4, 2023, only 90 miles after repair by Tesla, the exact same condition—parking brake function degraded. The vehicle, again, refused to disengage the parking brake. The vehicle suffered again the problem that rendered the vehicle in operable. The vehicle was again towed. On October 13, 2023, the vehicle was picked up from Tesla service for repair of the third defective and dangerous condition; the vehicle was driven locally and, on the freeway, to determine if Tesla had actually corrected the dangerous and defective condition. After about two hours in varying conditions and 90 miles, the vehicle was parked in the garage overnight. In the morning, the vehicle was loaded for an outing, and again the dangerous and defective condition occurred. This time, the vehicle could not be backed out of the garage; the tow truck was called.

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.

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.

On August 12, 2023, I went to the plano TX Tesla delivery center to pick up my new Teslay model as scheduled at about 11 am. Cst . The vehicle had 3 miles on it. After taking a couple of rounds around the delivery center and becoming comfortable with the default settings, I started driving back home which was 9 miles away. While on the drive, I noticed that the screen was showing “calibration in progress”. When I reached home at around 11:40 am. Cst, Tesla showed a total of 12 miles on it, and as the garage door opened, the screen showed stop as it said the calibration finished. As instructed, I stopped moving the vehicle on seeing hold/stop while entering the garage from the driveway. Suddenly, the car jerked forward forcefully, as if a magnet had attracted it inside with the pedal going down. The car went into the garage and hit the garage wall, damaging the common garage wall and the other side being the master bathroom (by damaging the cabinets, big wall mirror(s), counter top etc), and also damaged the front bumper of the car. I was shocked and terrified for a while. So immediately rushed to the center again and reported the incident at plano service center, who created a ticket on the same day. They said that this case would be sent to the engineering team for review. On Sep 10th, I got a reply from service saying they have reviewed the engineering study for the vehicle and the results displayed show that the vehicle operated as intended due to the use of the accelerator pedal at the time of the incident. Also reported to auto insurance who came and assessed the damage to the bumper which also rattles or squeaks. The service for collision is scheduled for Dec 7th 2023 by Tesla collision dallas center. What if the same happened on the main road or in the streets where I live where there are a lot of kids playing on the streets? when I think of it, I get scared and panicked and thank god that it occurred at my residence without any outside incident.

I was driving on the freeway on cruise control. As I was manuvering a slight curve in the road, there was a car in the lane to my right. All of a sudden my Tesla just started stopping almost violently. Luckily no one was behind me. It was the third time this has happened. Scary. No warning or anything.

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.

The Tesla Model Y autoaccelerated even with me pressing the brakes. The car was on regenerative breaking and instead of stopping it accelerated lunging into the walkway and almost killing a person. The car hit another car, 2 bike racks and a tree as well as concrete slabs beofr coming to a stop. There have been reports of unintended auto acceleration from Tesla cars. The car components has not been inspected by police, manufacturer or insurance representatives. There were warninngs, especially with the car reporting that sensors were not properly calibrated. I reported this to Tesla agents and they told me not to worry about it. I am injured with a left wrist sprain as well as neck and back injuries. I need Tesla to take ownership and pay dearly!.

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.

1. Wireless charging extremely slow. , connected charging is also slow. 2. Safety issue (camera): driving side left camera and blind spot monitoring camera specially sometimes stopped working automatically during driving in the highway or city, it’s pretty dangerous specially in the highway driving. During my long drive over July 4th weekend between 3-7 July happened several times, it caused auto steer mode forced disengage 3 times. Occurrence 8/8 between 12-3 am it happened about 6 times. It happens on and off almost everyday in some part of drive. 3. Safety issue phantom braking, in auto steer, brakes are suddenly getting applied when even are no objects in the front of car for no reason. Aug 4, it happened about 4 times between 7-9 am. (around 7:30-7:40)due to this big accident in the highway could have happened with truck, as truck was in normal speed 65 mph and due to sudden brake, vehicle speed came down to 35-40 mph, took control and move car out of road avoiding accident. This happened earlier instances as well during driving in the highways. But this time, I avoided death but got injuries. I need this car fixed for good or a replacement new car (preferably)or a refund. Enough, I’m scared of driving this car afterwards, as I’m concerned about security and life risk all the time. Aug 12 braking issues happened on around 6:40 and 7:30 pst. Aug 15 braking issue happened on the highway around 7:45 and 8:15 am pst hard to get a hold of customer service. They try to avoid physical service by service center by telling I need to provide exact timestamp and other nonsense remote debug and worst experience with the servicing. I asked for refund, no customer support no way to reach to discuss. 4. Range: promised range for Model Y is 330 m, get only 150-200 max, numbers are bloated and wrong. They tells it’s based on driving pattern and this range is based on 60-65 m/hr drive on a flat surface, which was not told or advertised in website or during purchas.

On 8/1/2023, driving between mojave, California and inyokern, California on highway 14, a newly paved and striped highway being followed by a mercedes van, I was doing 70 in a 65 zone. No traffic in front of us. No road signs. No turn outs. No side roads. No bridges, overpasses or underpasses when suddenly the car braked from 70mph to 48mph before I pressed down on the accellerator to keep the mercedes from hitting us. The front end of the mercedes dipped as he hit the brakes hard and he honked his horn which is what I would have done under similar circumstances. In the next half hour we experienced the phantom braking phenomenon five more times before my wife found complaints about "phantom braking", a phenomenon we'd never heard of or had been warned about. We turned off the automatic emergency braking and experienced no more events until after stopping in lone pine for charging. When we reentered the highway we experienced one more event before turning off the automatic emergency braking system, once again. Hours before we'd been in southern California driving on highways 5, 101 and 405 cruising along at 70 with traffic close in front and behind us. If the phantom braking had occured there, we might not be here today. Calling the Tesla dealership in reno the salesman was non-plussed about our experience and informed us we should be ready to hit the accellerator at all times. This is not an acceptable response to what could easily have been a major accident.

Two phantom braking incidents on road trip from CA to ut both on cruise control - not autopilot - no road obstacles or other vehicles present in both incidents 1st incident had road go from gray, older asphalt go to black new asphalt, which triggered a strong abrupt braking , jolting passengers 2nd incident - absolutely no obstacles or vehicles - random strong abrupt braking of vehicle stopped using cruise control after those two events - no more incidents.
