| Date | Component | Summary | Severity | Mileage |
|---|---|---|---|---|
| Jan 2024 | FORWARD COLLISION AVOIDANCE | While using adaptive cruise control, at highway speeds, there was aggressive, automatic braking when there was no vehicle in front of me. It happened about half a dozen times on a three-day trip from Indiana to Florida. Luckily, in each case there was no vehicle directly behind me. | Crash: No Fire: No | Unknown |
| Jan 2024 | UNKNOWN OR OTHER,VISIBILITY/WIPER | Heating failed in -10 temperature for approx 40 miles. Window became ice covered and would not clear. Interior of car was 33 degrees and heat came back on when plugged into charger. | Crash: No Fire: No | Unknown |
| Jan 2024 | UNKNOWN OR OTHER | Heat failed a second time in a few days. There was no heat in -7 temperature for 60 miles until I could get it to a supercharger. The car was at 60% charge when heat failed. | Crash: No Fire: No | Unknown |
| Jan 2024 | SEATS,UNKNOWN OR OTHER | The rear seat doesn’t detect kids under 50lbs. Putting the seat in car seat mode only disables the seatbelt alert and doesn’t keep the rear fans on. You can turn them on manually, but the car forgets that they should stay on if you precondition the cabin from the mobile app. Meaning that my child cooks in the back seat due to lack of rear cabin conditioning unless I remember to turn it back on in a buried menu every time. | Crash: No Fire: No | Unknown |
| Jan 2024 | UNKNOWN OR OTHER | Back up camera not functioning. | Crash: No Fire: No | Unknown |
| Jan 2024 | WHEELS,BACK OVER PREVENTION | Ever since Tesla pushed a software update to my vehicle on or around 12/20/23, the vehicle screen crashes and reboots every time I enter enter my vehicle. The software version is 2023.44.30.5.1. The vehicles systems; backup cameras, parking sensors, etc. are in operable for approximately 2 minutes during the reboot process rendering the vehicle unsafe to operate. I have reported this issue to Tesla on multiple occasions with no resolution offered other than a note that this is “considered” normal with the current software version. I was pushed software update 2023.44.30.8 on 1/8/24 and the issue persists. I have scheduled a service center appointment for 1/29/24. | Crash: No Fire: No | Unknown |
| Jan 2024 | FORWARD COLLISION AVOIDANCE | FSD Computer module (AP3 module) when starting to fail causes all active safety systems to top functioning, including but not limited to Lane Assistance, Automatic Emergency Breaking, Adaptive Cruise Control, Lane Departure Warning, Lane Keeping Assistance, Blind Spot Warning, Pre-collision systems, etc. This is due to the ECU that processes the video feeds from the cameras needed for these function begins to fail, and is not surprising. What is surprising is there are absolutely zero customer or service facing alerts for this issue. Customers simply are unable to manually activate some features, vehicle display has difficulty recognizing objects and lane markings, and the service menu (meant for vehicle service/repair) shows part of the ECU as critical in diagnostics, but does not provide an alert. I can only guess that as previously only half of the module was used at a time, with the second half being for redundancy incase of a failure on one part of the unit, still allowing for full functionality. However, in newer versions of the vehicles software both halfs of the module are used simultaneously to increase processing power, thus eliminating redundancy. It is possible that due to the past redundancy that a failure of one half of the unit was not considered a cause for alarm (though I would have hoped a failing component would have caused an alert, unless the companies hope was that one half would work long enough on its own until it no longer needed to be covered under warranty). However, given both processors and now being actively used there should definitely be alerts and warnings. In addition to losing the convenience of several of these systems there is also a negative safety aspect of systems such as accident avoidance, pre-collision seatbelt tensioning, and others may not work in a pending collision (not that I have seen these systems function properly in past collisions when the module was fully working). | Crash: No Fire: No | Unknown |
| Jan 2024 | UNKNOWN OR OTHER,FORWARD COLLISION AVOIDANCE | When autopilot is engaged, car unexpectedly brakes with no obstacle in front of car. Some called it “phantom braking”. | Crash: No Fire: No | Unknown |
| Jan 2024 | FORWARD COLLISION AVOIDANCE | The latest software update version: 2023.44.30.5.1 08a3a7856854 Is too stringent with having to keep eyes on the road that looking in the mirror causes it to beep. Also having to touch the steering wheel constantly is dangerous because if you move with slightly too much force, it disengages autopilot. I only use the autopilot feature on the freeway and I have never had an issue until this update, which I believe was made to make the system safer. In my view it is now much less safe since I’m not able to check my mirrors and ultimately I think it makes the autopilot feature useless. (I will not be using it) this is also less safe, in my view. Because before I would watch the road as the car steered, ready to take over, so it was like having redundant safety (human + machine). Now I’m back to just human safety. | Crash: No Fire: No | Unknown |
| Jan 2024 | UNKNOWN OR OTHER,LANE DEPARTURE | Autopilot feature is now unstable as I get constant nags if I look away for a few seconds to check my surroundings or check my navigation.i have been locked out of the feature multiple times over the past week forcing me to make navigation changes while manually driving. | Crash: No Fire: No | Unknown |
| Jan 2024 | FORWARD COLLISION AVOIDANCE | Driver assisst function for cruise control/autosteer failed/malfunctioned. Applied Emergency braking systems while autosteer/driver control active. Multiple times on freeway. OTA software Updates require additional data downloading and are not required to install. Never received update and safety issues resolved via OTA are already being exposed and they are not allowed to do anything to prevent any damage or loss to the vehicle. Wifi at all government EV charging stations is a basic requirement. | Crash: No Fire: No Injuries: 1 Medical attention | Unknown |
| Dec 2023 | FORWARD COLLISION AVOIDANCE | After the latest update the Tesla autopilot feature is very unsafe to use. The screen constantly pings and nags the driver to pay attention drawing my attention away from the road. The system has become so sensitive that adjusting the AC down a degree causes the warning to pop up which distracts the driver and in my opinion is significantly less safe than the older version. The warnings are too sensitive and the noise/warnings flashing are significantly more distracting | Crash: No Fire: No | Unknown |
| Dec 2023 | UNKNOWN OR OTHER | concerns about the latest software update for the Tesla Model 3’s autopilot system, which, in my view, significantly compromises safety. As a Model 3 owner for over two years, I have generally found the vehicle and its features to be reliable and safe. However, the recent update has introduced an overly stringent hands-on-wheel detection mechanism that is not only inconvenient but also potentially hazardous. The new update requires frequent and often forceful interaction with the steering wheel to assure the system of driver presence. This change is drastically different from my previous experience, where I received only one hands-on-wheel violation in two years. The current sensitivity of the system disrupts the smooth operation of the autopilot, leading to frequent and abrupt disengagements. I have found myself struggling to maintain the system’s activation, inadvertently causing the vehicle to exit autopilot mode multiple times. This issue goes beyond mere inconvenience; it actively detracts from driving safety. The need for constant and sometimes aggressive adjustments to satisfy the system’s requirements is distracting and can lead to erratic vehicle behavior. The irony is stark: a system designed to enhance driving safety and ease is now a source of potential danger and stress. The unpredictability and over-sensitivity of the updated system could lead to dangerous situations, especially on highways or in heavy traffic, where sudden disengagement of the autopilot can be particularly risky. As a driver, I now find myself more focused on keeping the autopilot engaged than on the actual driving conditions and surroundings, which is surely contrary to the feature’s intended purpose. I urge the NHTSA to investigate this issue as a matter of urgency. The balance between ensuring driver engagement and maintaining the operational safety and rel | Crash: No Fire: No | Unknown |
| Dec 2023 | VEHICLE SPEED CONTROL | The contact owned a 2021 Tesla Model 3. The contact stated that after reversing out of a parking space, then shifting to the drive position and lightly pressing the accelerator pedal the vehicle suddenly experienced unintended acceleration and drove forward at a very high rate of speed. The vehicle drove across a street and crashed into a building. During the crash, the driver sustained an upper torso and neck injury and was transported to the hospital. One person inside the building was also injured during the incident. No further information was available. The vehicle was destroyed and towed away. A police report was taken at the scene. The manufacturer was notified of the incident. The failure mileage was 12,400. | Crash: Yes Fire: No Injuries: 2 Towed Medical attention | 12,400 |
| Dec 2023 | POWER TRAIN,ELECTRICAL SYSTEM,FUEL/PROPULSION SYSTEM | My 2021 Tesla Model 3 shuts/powers down WITHOUT warning while driving with a battery charge >0%. This unsafe event has occurred twice now! While the battery gauge displayed 10%, I was driving about 60mph when all of these warning messages appeared prompting me to pull over. As soon as these messages displayed, my car lost all propulsion and I was left stranded in the middle of the road. Both times I narrowly avoided being hit by other vehicles traveling at high speeds since my car died in the roadway. The car was towed to Tesla on both occasions, and they weren't concerned about my safety issue in the slightest. Instead, they said the battery just ran out; however my car displayed that I had about 6-10% charge remaining. So, if the battery were completely depleted (like Tesla says), then the meter should have displayed a 0% reading at the time of the breakdowns or, there is something defective with the battery/computer. Tesla service has refused to investigate the cause of the safety issue and, thus, refused to replace the EV battery (even though my car is still under the manufacturer's warranty). Electric vehicles should not die/run out of battery at 10% charge. However, my EV has done so TWICE! Tesla says that I just ran the car out of battery but has no response when I show them the pictures and video proving that the car died when there was, in fact, a decent amount of charge remaining on the vehicle (PLEASE SEE ATTACHED VIDEO AND PICTURES). If your phone died at 10%, then you would take it back to the manufacturer and demand that they fix the defective product. However, Tesla refuses to help fix my defective vehicle and just tells me that it is "operating as intended". EVs should not just lose all propulsion mid-drive. This creates an unsafe vehicle for me to drive, for my two young daughters in their car seats, and for other drivers who might hit me. I can provide other Tesla owners who have had a similar experience. Please force Tesla to take action! | Crash: No Fire: No | Unknown |
| Nov 2023 | ELECTRICAL SYSTEM | Car was charging in garage overnight when an interior dash electrical fire started. Fire burnt dash and smoke damaged the interior or car. Fire smoldered itself out, and car was considered a total loss. Collision center that picked up vehicle stated that they believed the fire started from an electrical charging fault at the harness in the dash. | Crash: No Fire: Yes | Unknown |
| Nov 2023 | VEHICLE SPEED CONTROL,SERVICE BRAKES | The contact owns a 2021 Tesla Model 3. The contact stated that while attempting to park at 5 MPH, the brake pedal was depressed however the vehicle accelerated independently. As a result, the contact crashed into the two parked vehicles on the side of the parking space she was attempting to park. No air bags were deployed. One parked vehicle had an occupant and the other was unoccupied. There were no injuries or medical attention required. A police report was filed. The manufacturer was made aware of the failure and the vehicle was taken to an unknown dealer where it was unable to be diagnosed due to no available appointment. The dealer then suggested the vehicle be towed to the contact's residence where it currently remains in the garage. Tesla informed the contact that the brake system would not be inspected until she repaired the crash cosmetic damage to the vehicle. The approximate failure mileage was 33,000. | Crash: Yes Fire: No Towed | 33,000 |
| Nov 2023 | FORWARD COLLISION AVOIDANCE | The car's autopilot suddenly causes it to slow down without any apparent reason. There are no cars in front of me, and the speed limit hasn't changed. This unexpected deceleration is dangerous because the cars behind me may try to avoid me during the slowdown, which could lead to an accident. | Crash: No Fire: No | Unknown |
| Nov 2023 | ELECTRICAL SYSTEM,FUEL/PROPULSION SYSTEM | I was driving home from work on a two-lane highway when my car suddenly (and without any warning) lost all driving power and shut down while there was still battery left on the vehicle (roughly 10%). I could no longer maneuver the vehicle due to lack of propulsion, so my car died in the middle of the road. It was towed directly to Tesla service center where diagnostics were supposedly run. Their conclusion was the car died due to insufficient charge (even though there was about 10% battery left at the time of the incident). About a week later, the same EXACT thing happened! The car lost all power and shut down mid-drive without any warning with about 7% remaining. Both times, I had my home address in the car GPS (so it knew the exact distance I was traveling) and it never indicated once that I needed to stop and charge the battery. Again, I had the car towed to the service center where they reached the same "conclusion" that the car died due to simply running out of battery. When I showed them proof (pictures and videos) that the car died with charge left on the battery, they did not investigate the issue further. They simply stuck to their original conclusion and no longer wanted to help remedy my defective battery. I have video and pictures proving that my car dies without warning (on multiple occasions) while there is still charge left on the battery, but Tesla refuses to fix/warranty my car (let alone try to investigate or replicate the issue). They tell me that my car is "operating as intended" and is safe to drive, all the while knowing it is definitely not safe to drive. I'm especially concerned due to the fact that I drive my two daughters in my car. They both are very young and use car seats. What happens in the event that I am driving on the interstate with them in the backseat and my car randomly dies without warning? There would be no way to safely remove them from the vehicle (let along myself) before being involved in a serious high-speed accident. | Crash: No Fire: No | Unknown |

| Oct 2023 | POWER TRAIN | While drive after dark on a four-lane city road with no breakdown lane my vehicle alerted me of a problem and I should slow down. About five second later the car came to a stop and placed itself in park in the right-hand lane with traffic coming up behind me at 50 MPH. I was unable to locate the emergency flasher so I turned on the turn signal (I later found out the emergency flasher was located on the ceiling with white marking which were not visible in the dark). With the right turn blinker on I attempted to exit the vehicle but when I did, the turn signal turned off. This left me with a choice to leave a dark vehicle in the right-hand lane with moderate traffic or sit inside keeping the lights and signals on. No accident resulted but this was a very dangerous situation. The failure was a power converter which led to the disabling of both the front and rear drive motors. I was also unable to put the car in neutral and move it as far right as possible. I would have expected this type of failure to at least turn on the emergency flashers and give the driver the option of placing the car in neutral so it could be moved off the road. When i bought the car I specifically ordered the one with front an rear drive motors so failure of one would not completely shut down the vehicle. Seem like this power converter is a single point failure which leave the operator and other vehicles in a very dangerous situation. | Crash: No Fire: No | Unknown |
| Oct 2023 | ELECTRICAL SYSTEM,ENGINE | I was driving to work that all of sudden heard warning sound and the monitor displayed the "Shutdown" sign as well. The car lost its power and came to complete stop in the middle of the street. Luckily there was no car near me. I was not able to drive the car and had to tow it to the dealership. According to mechanic “the rear drive unit has failed internally”. This was extremely scary and dangerous and may have caused a fatal accident. The problem has been fixed. | Crash: No Fire: No | Unknown |

| Sep 2023 | SEAT BELTS | The rear middle seatbelt has permanently locked and is unusable. It occurred after having the rear seats folded down and was observed when replacing the seat-backs to their normal position. Tesla has refused to repair due to vehicle being out of warranty despite the vehicle not having been involved in any collision. | Crash: No Fire: No | Unknown |
| Sep 2023 | STEERING,ELECTRICAL SYSTEM | The contact owns a 2021 Tesla Model 3. The contact stated while driving out of a parking space, the steering wheel seized. The message "Front Motor Disabled. Continue Driving" was displayed. The manufacturer was contacted and provided remote assistance, but the failure persisted. The contact stated that the vehicle regained power steering functionality after an hour. The contact stated that the failure recurred while driving out of a parking space on another occasion. The vehicle was towed to a Tesla Service Center however, the failure could not be duplicated; however, the circuit board was replaced. The contact stated that the failure recurred while pulling out of a parking space on a third occasion. The vehicle was towed to a second Tesla service center, Tesla Sales (750 E El Camino Real, Sunnyvale, CA 94087) who informed the contact that an unknown software update was needed. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 17,000. | Crash: No Fire: No Towed | 17,000 |
