| Nov 2024 | UNKNOWN OR OTHER | The rear doors in this vehicle have no manual open option in case of a power outage such as a fire or submersion. This is a huge safety risk for back seat passengers, who are more likely than average to be children who could not figure out what to do in the case of an emergency | Crash: No Fire: No | Unknown |
| Nov 2024 | SEAT BELTS | The contact owns a 2021 Tesla Model 3. The contact stated that while a family member was attempting to use the rear middle seat belt, the seat belt failed to extend and was unusable. The vehicle was taken to a Tesla Service Center, where the seat belt was replaced. The vehicle was repaired as an out-of-pocket expense. The manufacturer was notified of the failure. The failure mileage was approximately 65,000. | Crash: No Fire: No | 65,000 |
| Nov 2024 | STRUCTURE | Tesla doors are opened from the inside of the vehicle by pressing a button. In the event of a power failure, the buttons will not open the doors. The front doors have an additional manual release to open the door. However, the rear doors do not. In a power failure mode, rear seat passengers will be unable to open their doors to exit the vehicle. Newer model Teslas contain the manual release for the rear doors. However, I have contacted Tesla and they have no plans to address my vehicle. I consider this a life threatening issue. Tesla should be required to retrofit any of their vehicles that have no way to manually open the rear doors. | Crash: No Fire: No | Unknown |
| Oct 2024 | VEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE,LANE DEPARTURE | My Tesla was operating in Full-Self-Driving Beta when it experienced a sudden uncontrolled accelration event. I was driving on [XXX] at approximatley [XXX] this morning. The road speed limit was 40 mph. The car display was correctly showing that the road speed limit was 40mph. The speed offset in the cars setting was limited to 5 mph max above the speed limit. While the car was driving it suddenly accelerated very hard from approximately 40 mph to over 60mph before I was able to stab the brake pedal and kick the car out of full self driving mode. There were no errors, warnings, or signs that anything was wrong with the car. I have also notified Tesla via the service request function in the Tesla App under the section for "software performance".

| Oct 2024 | STEERING,SUSPENSION,WHEELS | While driving, I started to hear a creaking sound while backing up and turning the wheel left. The sound became worse over the course of a few weeks. The steering also felt a little loose. I reached out to the manufacturer for a service appointment, and could only be scheduled about a month out. After a few weeks, while trying to parallel park, the car felt like a tire was stuck, or had a flat. I stopped the car to look at all of the tires and they looked fine. When I returned home, I tried to recreate the issue with my wife moving the car slowly from the driver seat while I looked at the wheels. As she turned and backed up, the creaking sound was very loud, but the tires looked fine. When she put the car in drive and began to pull back into the driveway, I could see the front passenger tire was turned abnormally far to the left, looked like it was leaning, and it was locked (not rolling). Once we had the car in a safe position, I jacked up the car and looked at the passenger control arm to see a bolt completely missing from the front suspension lateral link. The other bolt was 1/2 of the way out and barely holding on. If this had come apart at highway speeds, I am afraid it could have killed or seriously injured my family. | Crash: No Fire: No | Unknown |

| Sep 2024 | AIR BAGS | Front passenger safety restraint system fault alert popping up every few minutes while driving. It is the most irritating thing and there is no way for me to fix it without spending over $500 dollars. This is seemingly a common problem for this make and model through reddit posts and car forums. I was also told by a employee at the tesla service center that they see this very often. It is shocking that Tesla hasn’t taken responsibility in fixing this, when there is nothing any of us could’ve done to have this happen. I’ve seen people get quoted anywhere from $500-2,000 for this exact problem. It is so beyond distracting while driving. | Crash: No Fire: No | Unknown |
| Sep 2024 | UNKNOWN OR OTHER | Front passenger safety restraint system fault in sensor, sensors won’t stop going off and giving me warnings while driving. | Crash: No Fire: No | Unknown |
| Sep 2024 | FORWARD COLLISION AVOIDANCE: WARNINGS | I started receiving messages that the cameras were occluded and that there was an error and ALL of my system safety features were disabled. No front forward collision warnings, no emergency braking available, nothing available and the system computer that showed all of the traffic and everything completely disappeared from the screen, the car has literally gone blind. All of this started happening on with the camera issues in May, but I thought that it was a software issue and would be addressed in the next update, although the critical disengagements were supposed to be sent to Tesla. I took the car to the service center on 9/4/24 at 9am, and they stated that the did a system test and saw that the triple camera was showing a fault and so they replaced the camera and gave it back to me the same day. Everything worked for the rest of that day for a service that took at least 3hours to figure out. Today after I get off of work at 1pm and I go to initiate FSD and I get 3miles from my residence( I live <8mi from my job) and the system disengages again asking me to take over and all of my critical systems have yet again been disabled. My whole safety is compromised at this point yet again. I immediately bring the car back and they tell me that it's going to take them an additional 30-45 mins to "diagnose" the issue although it's the same thing that's been happening that was supposedly fixed yesterday. After that wait time the service consultant comes back and tell me that the car is throwing all kinds of codes and that, "It's still safe to drive." When I told that it cannot be safe to drive if all of the critical systems were disabled he suggested that I take it and they can do a remote log pull so they can look more into the issue or I can leave it as the part that's needed needs to be ordered anyway. I don't know how they can order a part if they're claiming to not know what's wrong with it. Something else is going on that they don't want to take accountability for! | Crash: No Fire: No | Unknown |

| Aug 2024 | ELECTRICAL SYSTEM | I am writing to file a formal safety complaint regarding a critical malfunction that occurred with my Tesla Model 3 on [XXX], in West Palm Beach, Florida. This incident raises significant concerns about the safety and reliability of Tesla vehicles, particularly following software updates. Incident Overview: On [XXX], around 5:00 PM, I placed my French Bulldog in the back seat of my Tesla Model 3 and closed the passenger side rear door. As I walked around to the driver’s side, all the doors locked automatically, and I was unable to open any of them. Despite multiple attempts to unlock the car using both my iPhone and key fob, the vehicle remained locked. My dog was trapped inside the car, and I became increasingly panicked, especially considering the extreme summer heat in Florida. I immediately contacted Tesla customer service, but after a 15-minute conversation, they were unable to unlock the car remotely. I was forced to call 911, and the fire department had to break the passenger side window to retrieve my dog. Even after the window was broken, the doors still wouldn’t unlock, and I had to pull my dog out through the shattered glass. Additional Details: The car was charged to 80% just a couple of days before this incident. After this incident, the car is completely dead. It is non-functional, and I cannot power it on or access any of its systems. The day before this incident, I completed a software update on my Model 3, which I believe may have caused or contributed to the malfunction. There is CCTV evidence of the entire incident, which I can provide upon request. My dog was severely traumatized by this experience and is now fearful of being in the car, even when it is parked in the garage. I was also extremely distressed during the incident, and the situation could have resulted in a much worse outcome. Please advise on the next steps for an investigation, and let me know if you require any further information or evidence.

| Aug 2024 | SUSPENSION | While getting a routine tire change, my mechanic alerted me to the fact that nuts were missing from the rear suspension on both sides. On one of them, the bolt had nearly slid out as a result, and could have been very dangerous as it did so. The tires had been rotated at this shop prior to this, and they had not noticed it. So the nuts must have loosened enough to fall out between 21,496 miles on 2/15/2023 and 26,278 miles on 6/16/2023. We never noticed anything out of the ordinary with regards to noise, vibration, or handling. | Crash: No Fire: No | Unknown |
| Aug 2024 | SUSPENSION | Without any warning from feel unstable, wobbly, or noisy, my car began pulling hard to the right as I was going straight on a small street. I was going about 10 m-15 miles an hour. My steering wheel did not respond to my efforts to straighten the vehicle and my brakes did not slow the car’s path. I was only stopped by two parked cars on the side of the road that I bounced off of. When I got out, bystanders pointed to the sheared tie rod on the front passenger side. The witnesses stated it was clear from their view that if I had been going faster on a wider street there would have been severe injury Instead of only three cars being damaged. My car was three years old and had passed its annual inspection one week before. The police were called twice but did not come within three hours so the car was towed without a police report. | Crash: Yes Fire: No Towed | Unknown |
| Aug 2024 | SEAT BELTS | Rear left seatbelt randomly stopped latching properly. Seat belt buckle goes into the latch but doesn't stick inside and just slides right out. | Crash: No Fire: No | Unknown |
| Aug 2024 | UNKNOWN OR OTHER,FORWARD COLLISION AVOIDANCE | Location: 35.084609,-92.414194 While driving through the roundabout north to south on Amity road, the car has twice now applied automatic emergency braking while exiting the roundabout. There is a billboard 200ft from the road with an image of a person on it. The car is confusing that as a person in the road. This has caused my dog to be thrown (thankfully buckled in) and us to almost be rear-ended both times. This is extremely dangerous issue. | Crash: No Fire: No | Unknown |
| Aug 2024 | AIR BAGS | I am writing to report a serious safety concern regarding the non-deployment of airbags during a recent traffic accident. The incident involved a collision where I was struck on the driver’s side front. Despite the severity of the impact, the airbags did not deploy, which raises significant concerns about the effectiveness and reliability of the airbag system in such scenarios. Incident Overview •Accident Type: Collision with impact on the driver’s side front •Airbag Response: No airbag deployment Safety Concerns The non-deployment of the airbags during this incident is alarming, as airbags are a critical safety feature designed to protect occupants during a collision. In this case, the failure of the airbags to activate could have resulted in serious injury or even death, depending on the circumstances. The lack of deployment suggests a potential defect in the airbag system that may compromise the safety of other vehicles of the same make or model. | Crash: Yes Fire: No Towed | Unknown |
| Aug 2024 | SUSPENSION | The contact owns a 2021 Tesla Model 3. The contact stated while driving at an undisclosed speed the contact noticed a knocking sound coming from the suspension with no warning lights illuminated. The vehicle was taken to the dealer where the vehicle was diagnosed as the front suspension lateral link separated. The contact was informed that the front suspension lateral link needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 51,543. | Crash: No Fire: No | 51,543 |
| Jul 2024 | FORWARD COLLISION AVOIDANCE | The contact owns a 2021 Tesla Model 3. The contact stated while driving approximately 35 MPH, the vehicle experienced phantom braking, causing the contact to lose control of the vehicle. The contact was driving in a rainstorm during the failure and stated that the vehicle had not hydroplaned nor had the accelerator pedal been released. The contact stated there was no warning light illuminated. The contact stated that the failure occurred another time during a rainstorm. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 74,000. | Crash: No Fire: No | 74,000 |
| Jul 2024 | UNKNOWN OR OTHER | Horn does not work. Seems to be a regular occurrence in this model. SAFETY ISSUE! | Crash: No Fire: No | Unknown |
| Jul 2024 | AIR BAGS | Passenger SRS system fault. Initial error is due to a fault with the occupancy sensor. Presumably disabling or degrading seatbelt pre accident tensioning and proper airbag deployment. Also causes repeated & distracting beeps throughout drive. | Crash: No Fire: No | Unknown |
| Jun 2024 | FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL | Ever since Tesla rolled out an update for everyone to beta test FSD, the adaptive cruise control has been changing speeds when near interstate type exits and entrances. I've had it change from 75 down to 40 mph which is dangerous in traffic. This change in speed some times is just a drop to the next 5mph increment, such as from 73 to 70. Sometimes it is more from 73 to 65 at the same place/exit. It is not consistent. The only thing consistent is it's near exits even when not in an exit lane or nearest lane to the exit. This "Feature" needs to be removed as it is unpredictable which makes it dangerous.

| Jun 2024 | POWER TRAIN,ELECTRICAL SYSTEM,VEHICLE SPEED CONTROL | The vehicle, a 2021 Tesla Model 3, had an episode of sudden unintended acceleration. I was almost stationary waiting to make a left when the car accelerated by itself, left the road, crossed a grass field at high speed and crashed into bushes. The vehicle was not on auto pilot, it resulted in damage of almost $ 20.000 as estimated by insurance. The vehicle is available for inspection, it will be checked by Tesla service after the damage is fixed. There were no previous warnings, this is the first incident of this kind. It is not clear what component malfunctioned, probably some electric/electronic device in charge of acceleration. It was obviously a very dangerous event that could have jeopardized my safety and/or some others. | Crash: Yes Fire: No | Unknown |
