general problems of the 2021 Tesla Model Y - part 2

I was accelerating out of a parking lot and was up to 30 mph when the vehicle suddenly shut down and the rear end began shaking. The control screen went completely black/off. I could not accelerate at all. A semi truck was coming from behind and the vehicle came to a sudden stop within a few seconds. I could not coast and pull into a parking lot. It felt like an emergency brake was turned on or the back wheels locked up. I had to turn into the center turn lane. Vehicle doors would not open and hazard lights would not turn on. Opened manual door handle and forced my way out. Shut door as I ran to safety and the window cracked. I could have been severely injured if that semi hit me from behind and especially if this would have happened on the freeway. Very scary that a car can suddenly shut off like that while driving. After repair I was informed that the 12v battery had failed. They said it’s very rare and they have not seen that happen while the car was driving.

Dear Tesla customer support, I hope this email finds you well. I am writing to express my extreme concern and disappointment regarding a serious malfunction I experienced with my Tesla vehicle, Model Y, on 08/01/2023. The incident has left me deeply troubled and has raised significant questions about the safety and reliability of your vehicles. On the aforementioned date, while I was driving my Model Y, I noticed an unusual burning smell coming from the vehicle. Shortly after, the cruise control system began to malfunction erratically, leading to a loss of control over the vehicle's speed. In a matter of seconds, the display and all lights on the dashboard went dark, leaving me unable to monitor crucial information such as speed, battery level, and vehicle warnings. Worse yet, the electronic power steering suddenly failed, causing an immediate stiffening of the steering wheel and making it incredibly difficult to control the vehicle. As a result, my car veered into a curb, causing damage to the wheels and suspension and fire. I cannot stress enough how distressing this situation was. Not only did it put my safety and the safety of others at risk, but it also raises questions about the reliability and effectiveness of the various systems within the vehicle. I have always trusted Tesla's commitment to innovation and cutting-edge technology, but this incident has shattered my confidence in the vehicle's reliability. I am writing to urge you to take immediate action to investigate this malfunction thoroughly and provide a comprehensive explanation for what transpired. I request a detailed analysis of the root cause of the issue and assurance that appropriate measures will be taken to prevent such incidents from occurring in the future. I have been a loyal Tesla customer for 2 years and until this incident, I have been delighted with the exceptional performance and features of your vehicles. However, this incident has left me deeply concerned, and I sincerely hope.

The 12v in the Tesla died without any warning. I put my 2 year old child in his car seat directly behind the driver's seat. I closed his door and went directly to the drivers door and could not get it to open. I tried the app multiple times including refreshing the app and restarting my phone. I also tried using the keycard to unlock the doors. I tried using my spouse's app which also didn't work. Nothing worked and my son was trapped in the car in 100+ degree weather for over 15 minutes. My husband had to pry the front passenger door open so that we can could get him out and in doing so caused the window to crack. When contacting Tesla, they sent out a tow truck to get it to the service center. They fixed the problem and told us there was a manual latch for the front and rear seats, but there was no way our two year old would have been able to pull the latch, let alone reach it. There is also no manual latch on the exterior of the car that we could have used.

Battery is not able to charge . The message shows need services bring the car to Tesla service center , they told us the battery need to be replaced. They did not tell us what caused the battery to die. The car has about 30000 miles on it . Daily driving to work. Don’t understand why the battery dies so fast . Does anyone report the same problem on 2021 Tesla Model Y ?.

Yesterday morning I opened the car and put my dogs in the back seat. I closed the door. I then tried to open the driver’s door but the car became unresponsive. I tried to release the charging cable connected to my home charger. The car did not respond via bluetooth or mobile or access card key. The car was completely dead with my dogs inside. I live in palm springs. It was 90 degrees and sunny outside. I called Tesla roadside. Towing was dispatched. Eventually the passenger doors opened and I got the dogs out. My car was towed away. Dead. Nobody at Tesla seems to see how dangerous this situation was. It could have been a baby locked inside the car. Tesla has no culture or attitude of taking this seriously or seeing this as a potentially life threatening issue. It’s shocking to me how everyone I spoke with at Tesla saw this as just another glitch or customer trouble ticket. The severity of this issue was completely lost on every Tesla employee I encountered. Tesla must be held accountable. According to the tow truck driver this happens frequently. People are often stranded in extreme heat due to this 12v battery failure. This issue must be investigated and Tesla should be forced to respond.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? after closing the passenger side door, the 12v battery that controls the Tesla cabin died without any prior warning or car notification that it needed to be replaced, as a result the car instantly powered down , disabling the a/c, windows and door locks and we were unable to open the doors to access the car. 2. How was your safety or the safety of others put at risk? at the time of the event no, just our personal belongings were trapped inside the car but as a parent of a small child I usually put my child in her car seat first and close the door then get in my seat, if this had occurred with my child being in the car , my only option would be to smash in the window to get her out as the car has no back up system to open the car doors if the 12v battery dies. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? yes , the Tesla had to be towed to the service center we’re they had to run system test and replace the 12v battery. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? yes by Tesla , they ran test and determined that the 12v battery was the issue. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? no warnings or notifications were given prior , Teslas are suppose to receive a notification to alert the owner the battery needs to be replaced as their cars have a lot of 12v battery drain.

The contact owns a 2021 Tesla Model Y. The contact stated that while driving at 45 mph, the vehicle hydroplaned shortly after he merged into another lane. The contact stated that he left his foot off the throttle in an effort to not lose control of the vehicle; however, the vehicle's automated regenerative braking feature engaged and the vehicle drifted at a 90 degree angle. In an attempt to avoid hitting another vehicle, the contact hit a concrete barrier. The air bags deployed upon impact. The contact suffered neck pain and a gash to his right arm but did not seek medical attention. A police report was filed. The vehicle was towed to an independent mechanic where it remained in their possession. The manufacturer was notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 40,000.

The contact owns a 2021 Tesla Model Y. The contact stated that while the vehicle was in autonomous self-driving mode driving 30 mph, the vehicle failed to stop as another vehicle was approaching, causing the other vehicle to swerve. The contact stated that the vehicle responded insufficiently after the speed was set to 30 mph. The contact then stated that a week later she received notification of NHTSA campaign number: 23v085000 (steering, electrical system). The manufacturer was notified of the failure and the contact was able to perform an ota software update; however, the failure recurred. The vehicle was not repaired. The failure mileage was approximately 20.

The car started to malfunction its ability for regenerative braking (regen. ) upon release of the accelerator. The car felt as if the regen feature was slipping - so instead of a constant brake and deceleration, the car could be felt moving forward as if accelerating. Then while driving on freeway at 65-70 mph, car lost its ability to brake when I pressed on the brake twice, instead of slowing it felt as if the car just continued at its current speed. Then the car cut its power and flashed an alert "power reduced - exiting and re-entering vehicle may restore operation" it then flashed an alert "pull over immediately - unable to drive". According to Tesla, they said it was the "lh body harness. Found that the harness was not creating an efficient connection" but they never directly addressed why it felt as if the car was accelerating when I pressed on the brake. Safety was critically comprised for myself and others who I could have hit in a vehicle collision since the brakes did not respond accordingly and felt as if it accelerated or continue to maintain its speed. The problem was confirmed by Tesla but they only addressed the car going into what they refer to as "limp mode". Car was inspected by Tesla and diagnosed the problem to a faulty/bad body harness that caused an improper signal. No warning lights or messages prior to the failure. Symptoms started the morning of the incident with the noted regen not fully engaged/working correctly. I did not have any feature setting which would have caused or replicated the lack of regen. I can provide the dealer invoice if needed.

Defective battery, wont charge past 30%.

On February 20, 2023, my infotainment system console and screen completely failed as I was backing up to a supercharger. This started with the typical lag I have filed service complaints for before, the camera occlusions, and then nearly caused an accident with the barrier pole in front of the supercharger. This is the eighth near miss in over a year of ownership and the 27th occurrence of issues related to the infotainment system console and screen. Often, it is burning hot, other times it is woefully underpowered to accomplish anything in a timely manner (if at all) when these incidents occur. I have been to the Tesla service center twice about this very issue. Each time, I was told software update would be issued that would fix the problem(s). That has never been the case. With everything so reliant upon that center-mount display and its associated computer in this model of vehicle, it has to be considered a must-not-fail component to the extent humanly possible. I am taking this vehicle in for a third time for this and multiple other issues that seem to some degrees associated with the issue. After badgering the Tesla helpdesk personnel with demands to replace or fix the issue, they have told me on February 23, 2023 that they will be replacing the computer next week (whether this is to evaluate the device for issues or to hide evidence to their culpability in an incompetent design flaw, I cannot be sure).

The driver side window doesn’t roll all the way up when trying to close it automatically with one button push. It goes partially up the side and then will automatically roll down.

The car stopped suddenly in the middle of the street. By the grace of g-d, this happened on a quiet street because we decided to take a detour and could have instead been on the freeway! we were with our 3 young children (all in carseats). We could not restart the car after it stopped, and there was no warning it was going to stop. We were not using autopilot.

Vehicle has been inspected by the manufacturer and they have advised it has been completed/fixed but it's been in more than four times within the last 12 months.

Tesla y unintended acceleration! driving my Tesla I got a phone call that did not show up on screen then 1-3 seconds later my car took control of itself and rapidly accelerated. I had no control with no steering or brakes. Powerless inside an accelerating vehicle! the car then crashed up on the median through a private community light post and into a tree. The car did not stop until the battery was severed and destroyed by the tree. All airbags went off and all glass shattered. There was no prior warning at all. Insurance adjuster deemed the car a complete total; not worth repair.

The contact owns a 2021 Tesla Model Y. The contact stated that while driving at slow speeds, while making a turn beside the driveway, the vehicle crashed into the curb, roll down the hill, and crashed into a tree. The contact stated that the brake pedal was depressed, however, the vehicle continued to roll. No air bags were deployed, and no injuries were sustained. The vehicle was taken to the repair shop where the headlight assembly, the hood, and the full front assembly of the vehicle were replaced. The manufacturer was made aware of the issue. The failure mileage was approximately 400.

The contact owns a 2021 Tesla Model Y. The contact stated that the vehicle had received a software update through the WI-fi from Tesla. The contact stated that the camera for the autonomous self-drive feature had become excessively sensitive sounding the alarm for the occupant detection and lane assist at the slightest movement. The contact stated that the issue caused multiple distractions while driving. The contact had not taken the vehicle to the dealer. The contact had informed the manufacturer of the failure. The manufacturer referred the contact to the dealer. The approximate failure mileage was 36,314.

The rear hatch can be opened while the car is in drive or reverse from a remote input from the app. On several occasion my hatch has opened from a remote input while in traffic while stopped at red lights. Tesla says this is normal behavior. So what is possible is someone can open the hatch from a remote input from anywhere without being able to see the car. My concern is when this has happened item could have fallen from my trunk into traffic resulting in damage or vehicles behind me. To close the hatch you must place the car in park first. Having a vehicle in park in traffic could result in a collision. You can not move the vehicle while the hatch is closing or it stops closing it takes several seconds to open or close the hatch and additional time to realize you must place the vehicle in park to close it. Remote input to operate the hatch should be disabled while the vehicle is in drive or reverse. The event has occurred on 4 occasions while driving the vehicle over the last year.

On 6/25/22 our 2021 Tesla Model Y with 16,163 miles had a sudden unintended acceleration, it didn't responded to the breaks and within seconds hit a parked car and finally stopped when it crashed to a large tree. It was a "total lost" by the insurance. Around 1pm on a clear sky day, driving out of a small gated residential community, before exiting I pulled over the side of the road for a few minutes, when I resumed the car suddenly accelerated to what felt like full speed. While I stopped by the side of the road the car remained in "d" mode, when I resumed I forgot that it was already on "d" and pushed the shift level down; we think the car went to cruise control to the last used speed which was probably a highway speed. The breaks didn't stopped the car and didn't cancel the accelaration. It traveled out of control less than 150 feet before it crashed to a large tree. For some "unknown" reason, the footage of the 4 cameras got erased from my usb memory stick. The only video left was the front camera and that video was cut a couple of seconds before the first crash. Tesla took almost a year on their "investigation" and the result was a long technical bs indicating that they didn't found anything abnormal. Driver airbag deployed.

Every two weeks or so, the screen goes blank. When parked, you can do a vehicle reset and after 2 or 3 tries the screen with turn back on and the car is able to be driven. Sometimes, the screen will go blank while driving. This will require the driver to pull aside, power down the vehicle, and try to reset it. This is a huge safety issue when the screen goes blank when driving. Tesla says there's nothing wrong, or try a reset, or the next update will solve it. When there is a bug like this on an ev it is a huge safety issue.

On June 28th 11:50pm with 174 mile range, my Tesla Model Y lr died while driving on fwy 5 with my 10 year old. I barely had time to exit, it gave me warning “pull over safely” “vehicle shutting down”. I barely made it to off-ramp, my car completely shutdown at the end of off ramp. Could not put it to neutral, me and my 10 years old had to exit the car immediately, called tow truck via Tesla app. Tow truck showed up in 20 mins, can was not drivable. This could have been much worst, if I was not able to exit and my car stuck on middle of the freeway at night. This is a huge safety concern.

The back windows go up and down when trying to roll them up.

We are experiencing two issues with our Tesla y, one of which I have come to learn is common. That issue is the cruise control will suddenly "disengage" forcing the brakes on, either actively or just through the regenerative components. This has happened in several conditions from high speeds on interstates (>55 mph) and on smaller state highways (<55mph). The primary concern is being rear ended by cars following; effectively the Tesla is "brake checking". I am not aware of Tesla pushing updates or addressing this issue in any typeof inspection. There are no warnings, and I have noticed no pattern as to why it happens (and it happens frequently). I have notified Tesla of the issue. The second issue is that the control/infotainment screen has frozen and gone blank on at least four occasions. This as well has happened in various conditions, most recently on both legs of a long roadtrip on the highway. It effectively leaves all control of the car other than steering and velocity out of our control. It is scary. There are no warnings and I am not aware of Tesla doing anything to address the issue though I am aware that it is happening to other vehicles.

Cameras did not work with turn signals. Wipers stopped working. Then the screen went blank. I don’t know if the hazard lights worked initially when pressed. This occurred in a rainstorm going over 60mph. We almost were in a wreck due to not being able to see and needing to exit highway immediately. Stopped car. Rebooted. Difficultly opening charging dock 15 minutes later. Have called Tesla in columbus, ohio and left message.

Going 40 mph on CA 210w in left lane. Full self driving available on vehicle but no autopilot/lane assist activated at time of incident. Steering wheel locked up completely; I was unable to turn the wheel at all so I ended up drifting across 4 lanes of highway (miraculously didn’t hit anyone) and ended up under a semi. Car airbags did not deploy and system did not detect a collision. Contacted Tesla to ask about the cause of the accident multiple times; never got an answer. They had us pull the usb in glovebox and see if anything is on there but there wasn’t even though dash cam was activated. They “escalated” the ticket to a supervisor and have been ghosted ever since asking for an answer. We scheduled a service appointment to have them check out the vehicle and they canceled it. It is a miracle that I did not die; I have severe ptsd from the incident which has affected my career negatively. I would like Tesla to take accountability for things like this; it’s scary that they don’t and threaten legal action instead.

The contact owns a 2021 Tesla Model Y. The contact stated that the display screen would intermittently fail to operate as needed, without warning. The contact also stated that the power windows failed to operate as needed. The contact had taken the vehicle to the service center on multiple occasions for various updates; however, the power window failure persisted after each update. The contact recently received notification of NHTSA campaign number: 22v702000 (visibility). The contact stated that the back-up camera was displaying a distorted image while the vehicle was in reverse(r). The vehicle was not repaired. The failure mileage was approximately 9,400.

The main instrument cluster / screen turns off without notice while the car is in motion. This results in the loss of all displays and controls, such as 1. Speedometer 2. Defrost control 3. Turn signal noise 4. Windshield wiper setting 5. Battery capacity gauge and many more.

The incident occurred after a rainstorm and there was some debris laid out across the road. We were travelling in the morning before sunrise at 20 mph and we felt a small branch or object hit the underside of our car. We took it out to drive again at noon time and it warned us that the coolant was low and that car may not start up once shut down. We towed it to Tesla service center in paramus NJ and they informed us of the condition. They informed us that the coolant pipe was punctured and the coolant spread onto the battery. They explained to us that the branch hit an area and caused the coolant to leak inside the battery and there is no plate to protect it at the underside of the car. They also informed us that there could have been a fire accident if we put it on charge after the underside collision. They also informed us that the coolant pipe was plastic. Despite this flaw in their design, they insist that they will not cover it since it was an external issue and have asked us to pay close to $16,000. Please help.

Multiple phantom braking incidents using cruise control on 2 lane roads when there is no hazard.

Car rapidly brakes when in cruise control and auto pilot. Will also rapidly brake when a car passes by. It will always be random and sudden. Also, occasionally the screen will turn off and I will lose the screen completely and not know my speed.

My wife and I were driving south on interstate-93 in nh on superbowl Sunday. Traffic was heavy and we were traveling about 65 mph when our 2021 Model Y Tesla started beeping and the following message came on the screen - “pull over safely, vehicle shutting down”. My wife was driving and had just enough time to cross over three lanes to get into the breakdown lane before the car came to a sudden stop. The car did not want to restart. We called the Tesla service center and they were about to order a tow truck but we asked if there was a ‘ctrl/alt/del’ type option. She had us select safety>power off. When our Tesla came back on everything was seemingly normal so the service center said ‘this is very rare’ and that it should be okay to drive. We drove another few miles down 93 and luckily took an early exit ramp because the car shut down again at the bottom of the ramp. My wife and I restarted the car again and managed to limp home in some sort of “power reduced” mode (I. E. Painfully little acceleration). This was potentially a very dangerous situation! luckily we were able to safely get into the breakdown lane but there wasn’t much time to spare.

The Tesla Model Y had a software update at 12:05 am on Feb 13, 2022, which was complete. I drove the car to local ymca at around 8:15 am on Sunday Feb 13, 2022, for my swim exercise and drove it home at around 9:30 am. I planned to park it by backing up to my driveway so that I can charge it. I positioned my car, with the front facing my neighbor's house. My foot was on brake and my right hand was moving the drive stalk towards r for reverse. The car all of the sudden flew forward on its own! it was only stopped after it hit my neighbor's house, making a big hole into her house, and causing severe damages to it outside and inside (smashed furniture and falling glassware), as well as to her landscaping. When this happened, my foot was still on the brake but pushing brake did stop the car. Additionally, hitting a tree also did not stop the car. Only the house and its strong frame stopped the car. The front of the car was totally damaged, including pieces falling out of the car and a big piece under the car falling down. Please come by immediately to take photos and examine damage. I called 911 immediately. The police and emergency trucks came. Since no one seemed to be visibly hurt (I had a whiplash and headache due to impact but was more was scared and shocked), the emergency medical crew left. The police said they are not making a report because the accident happened in private driveway and no crime was involved. I called liberty mutual to file a claim and was directed to file it online. I never bought the Tesla autopilot package but the new software update showed autopilot is an included package. This is a problem. I called Tesla customer service and reported this serious software malfunction. Thinking back, software problem caused another safety concern that started on Feb 6, 2022. Not only the right passenger door cannot be opened from outside, it also cannot be opened from inside. Someone could be trapped inside. This is a safety alert!.

The heat pump that supplies all heated air to the cabin stopped working completely. Safety was impacted because my windshield fogged up, making it impossible to see clearly out of my windshield or other windows. It was 11°f outside with no heating. I am not sure if a service center has been able to reproduce the issue, but I have images of the fogging and the error message. Nobody has inspected the issue yet. I received an error message "vcfront_a447" and "cabin climate control system requires service" I have received this error message in two separate occasions now, both when it was lower than 15°f outside.

Heat pump failed when driving in minus 7f weather. Windows fogged up and car was dangerously cold. Only heat seater and steering wheel to stay warm.

The heater of the vehicle just stop working, due to mn cold weather and since there is no heat and just cold air blowing. It freezes the windshield and frost would build up with out any way to melt it since there’s no heat. It also fogs up the interior in the car since you can’t open the windows due mn minus windchill weathers. It’s hard to see and keep warm in a cold climate state. Tesla doesn’t see this is an emergency and it’s very concerning.
