| Aug 2023 | AIR BAGS,SEAT BELTS,SEATS | Front passenger safety restraint system fault intermittently appears and disappears. Might be defect of manufacture of harness squezed. Lots of users are complaining about said and manufacture wants $500 to repair what seems to be a recall. https://teslamotorsclub.com/tmc/threads/front-passenger-safety-restraint-system-fault.161485/page-5#post-7714894 | Crash: No Fire: No | Unknown |
| Aug 2023 | STEERING | On July 19th around 6:45pm, I was driving on the left most lane of I-95S in VA towards NC near Exit 41 at 70mph. The care suddenly steered hard left towards the median. I tried to steer it back but the steering wheel was locked and would not let me steer back. The brakes would also not work and the car drove into the guardrail and spun180 degree and hit the guardrail again and spun180 and did that one more time and stopped facing the oncoming traffic. The impact tore the entire front left-wheel assembly off my Tesla, sending it more than 250 yards forward. Damaging the left side of the car front to back but the airbags did not deploy neither did the seatbelts locked. Fortunately, the entire cabin was intact and I walked away without any external injuries. | Crash: Yes Fire: No Injuries: 1 Towed Medical attention | Unknown |
| Aug 2023 | STEERING,ELECTRICAL SYSTEM,FORWARD COLLISION AVOIDANCE | 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 | Crash: No Fire: Yes | Unknown |
| Aug 2023 | ELECTRICAL SYSTEM | 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. | Crash: No Fire: No | Unknown |
| Aug 2023 | STEERING | The steering wheel locked up for 3 seconds. I returned the vehicle to Tesla and they said they replaced the control arms. I suspect the bearings in the steering control arms seized. I suspect the steering control arms are not robust enough to handle the weight of vehicle. | Crash: No Fire: No | Unknown |
| Aug 2023 | VEHICLE SPEED CONTROL,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | Phantom Braking. When there are refractions on the road seen in my lane in bright sunshine. Also in a 2-lane highway with oncoming vehicles that have lots of chrome also in bright sunshine. Never happens at night or when cruise control not enabled. | Crash: No Fire: No | Unknown |
| Aug 2023 | UNKNOWN OR OTHER | My mother was involved in a fatal crash on August 30, 2022. We believe there was something unusual that occurred with the Tesla Model Y as it was on a quiet residential street and the car seems to have accelerated suddenly and she hit a pole. We are still waiting on the California Highway Patrol report. | Crash: Yes Fire: No Fatalities: 1 Towed | Unknown |
| Aug 2023 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE | I was on the highway with cruise set to 80. With no vehicles anywhere near in front of me, the car brakes hard and the cruise was set to 50. I was able to gain control by hitting the accelerator but slowed down quickly from the phantom breaking. | Crash: No Fire: No | Unknown |
| Aug 2023 | STEERING | I encountered the issue where my car would lose all power steering and the following warning would present itself in 3 different errors "power steering reduced". The typical fix I came up with to resolve the issue was to put the car in park, exit the vehicle and then open a.nd initiate the vehicle with the physical key. The problem was first noticed in April of 2023 and an initial review of the vehicle by Tesla was done on May 9th after the vehicle encountered this issue while I was at a traffic stop. Issue was not resolved as it returned 2 weeks later which prompted me to send it back to Tesla on June 11th. Vehicle was kept for 14 days. As of August 1, 2023 the issue has not returned | Crash: No Fire: No | Unknown |
| Jul 2023 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | Approximately 11:26 am on Thursday July 27, and approximately 110 miles east of Gallup, New Mexico, I experienced when driving a 2021 Tesla Model Y, a series of extreme phantom braking events. One phantom braking event resulted in an extreme braking and the car gave a loud alarm signal. This happened while passing two rather closely spaced semi-trailer trucks that were in the right lane of the interstate highway 40 roadway going westbound. Both trucks were traveling without making any unusual movements. They were steadily traveling between 70 and 80 mph. There was a large SUV following our vehicle. This event resulted in an extremely hazardous condition. A high-speed rear-end collision was imminent. I, as the driver of the Model Y, immediately accelerated and steered over to the left-lane shoulder. No collision occurred and I was able to pass the two trucks and return to the right lane. Clearly, this behavior of the Model Y is extremely hazardous and must be corrected. It is my recollection that I had disengaged the auto steer mode prior to passing the two trucks and then reengaged the auto steer after passing the two trucks and moving to the right lane. I have experienced this behavior before as I have been driving the vehicle for the past two years of my three-year lease. Strangely it always occurs, it seems when driving on rural interstate, such as this case. Fortunately, these experiences helped me to instantly respond by accelerating and moving onto the left lane shoulder to avoid a disastrous accident. It is appalling that this has been happening. The Tesla gives absolutely no indication of the cause of the urgent breaking either before or after the event. Also there has been no notifications from Tesla on this dangerous phantom breaking. I am sending this report to Tesla and the NHTSA. | Crash: No Fire: No | Unknown |

Time of day independent. | Crash: No Fire: No | Unknown |
| Jul 2023 | STEERING,SERVICE BRAKES,ENGINE | On, June 24th and July 15th my vehicle experienced multiple errors while driving. Indicator lights stated the following: stability control disabled, dash cam disabled, traction control disabled, regenerative braking disabled, emergency braking disabled. On July 15th the front motor was disabled, causing the vehicle to not have enough power to continue up the mountain. The vehicle stopped in the middle of the highway, and started rolling backwards. After I was able to turn the vehicle around, the brakes were grinding, and did not stop the vehicle. There as a smell of burnt rubber, and the brake pedal started “ popping” and moving back and forth on its’ own. The engine failure has occurred twice, and all of other errors have occurred 4 times since June 2023. I made an appointment with the Tesla service center and they cancelled my appointment, for no reason. After the July 15th incident, I took the vehicle into the service center myself. These issues are intermittent, which is very dangerous. The car will experience these errors, and then operate as normal. Tesla told me that they thought this entire thing was “ strange” and that they have never heard of this issue. All logs on the vehicle show these errors, and I have a witness. Tesla has not updated me with the status of my repair, or even a diagnosis. I am terrified to drive this vehicle. | Crash: No Fire: No | Unknown |
| Jul 2023 | SEAT BELTS,SEATS | On 7/18/2023 - my car reported the following: Replace Occupant Classification System (OCS) of Front Passenger Seat. In essence the seat sensor on the car malfunctioned and needed to be replaced. Tesla charged me $466.29 to replace this and said that this was not under warranty, even though this was a safety issue on their part. | Crash: No Fire: No | Unknown |
| Jul 2023 | FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | My family and I were driving from San Diego to Arizona on Interstate 8. I was utilizing autopilot (adaptive cruise control with lane keeping assistance) and 4 different times the car slammed on the brakes from approximately 75 mph to 60 mph. We were driving on a bright, sunny, extremely hot day (116 degrees). Luckily there were no cars behind us or we could have been rear-ended. It's also noteworthy, there were no cars/vehicles in front of us or objects in the road when the phantom braking occurred. I now no longer feel safe using autopilot on our Model Y. No warning messages appeared and no additional information was provided by the car. We have used autopilot on several other road trips and never experienced this issue. | Crash: No Fire: No | Unknown |
| Jul 2023 | SERVICE BRAKES, HYDRAULIC,VEHICLE SPEED CONTROL | The contact owns a 2021 Tesla Model Y. The contact stated while driving 65 MPH, the vehicle independently accelerated at high speed. There was no warning light illuminated. The contact desperately depressed the brake pedal, and the vehicle came to a to stop. The dealer was contact, but the vehicle was not diagnosed or repaired.

| Jul 2023 | ELECTRICAL SYSTEM | 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. | Crash: No Fire: No | Unknown |
| Jul 2023 | ELECTRICAL SYSTEM,UNKNOWN OR OTHER | 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. | Crash: No Fire: No | Unknown |
| Jul 2023 | STRUCTURE,VISIBILITY/WIPER | When driving at highway speeds (55 MPH and above), the driver's side rearview mirror vibrates, making it difficult to see and identify back automobiles. This is a safety hazard when exiting the highway or merging the lines when the outside weather is raining/dark/snowing. | Crash: No Fire: No | Unknown |
| Jul 2023 | FORWARD COLLISION AVOIDANCE | I was driving the speed limit with the adaptive cruise control engaged on I-95 in Maine with no one in front of to the sides of me. All of a sudden without warning my car brakes on the middle of the highway. I regained control right after and did not use the adaptive cruise control for the rest of the drive. | Crash: No Fire: No | Unknown |
| Jun 2023 | SERVICE BRAKES,FORWARD COLLISION AVOIDANCE | Phantom braking in autopilot. Traveling at 75mph with traffic behind, fortunately the car behind was not following closely.

| Jun 2023 | ELECTRICAL SYSTEM,EQUIPMENT ADAPTIVE/MOBILITY | 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. | Crash: Yes Fire: No Injuries: 1 Towed | 40,000 |
| Jun 2023 | FUEL/PROPULSION SYSTEM | I was driving my car when suddenly it started losing power while I was driving 70 - 80mph, and I noticed two messages on the screen: "power limited, schedule service" and "power reduced” and then my car would no longer drive above 50 - 55mph and the heat in the car was reduced . Concerned about the issue, I promptly contacted Tesla to have my vehicle serviced. However, to my surprise, after performing a diagnosis, they insisted that there was nothing wrong with the car. The component I believe failed is the heating pump, which is still installed in the vehicle. My safety was put at risk because I was on a highway with the speed limit was 75mph, and if other people were not paying attention they may have crashed into me due to me suddenly slowing down and also things could of turned fatal if someone were to be stranded in the middle of nowhere without a working heater when it is 0° outside. The issue was confirmed by the manufacturer as a “ engineering issue” that would be addressed with a software update. | Crash: No Fire: No | Unknown |
