My Tesla Model 3 was delivered on 14 December 2022. I first drove it on 16 December 2022 and that day I had an accident. I was about to park my car and I was already on the designated parking slot when the car made a sudden Un- commanded acceleration. I first hit the handicap sign, but the car did not stop and apparently the collision avoidance safety feature did not work. The continue to accelerate and I hit a restaurant establishment. The police came and I reported the incident to my insurance (Geico). The police (Mr. McClure) gave me the case number 2238293. Geico is taking care of the repair which would cost over $10K and the property damage, which added up to 10K. I went to the Tesla service center in Carlsbad and Mr. Hyuma said that I can request for the log. I guess it is the EDR. …
On Jan. 1, 2024 at around 2:19-2:20PM, the vehicle in front of me made a sudden brake causing my vehicle to trigger the Automatic Emergency Brake. My foot was on the brake pedal as well, I even floored the pedal to make my car stop right away but it continued anyway, the pedal felt so loose/soft. My car almost made a full stop but when the vehicle in front of me started moving, the car started to somehow accelerate, I was confused as to why the car was moving when my foot was firmly pushing the brake. This unexpected move caused me to rear-end the vehicle in front when they abruptly stopped for the second time. My thought is since the car in front moved, the Tesla thought the vehicle in front was no longer a threat and stopped applying the brake to make a full stop. I watched a lot of AEB videos online. 1. …
On [redacted] around [redacted], my daughter drove her Tesla Model 3 on [redacted] from school. Two strange/scary accidents happened to two different Tesla cars (Model 3 and Y). It was raining with low/medium visibility. One of the cars was driven by my daughter, and luckily, both drivers were safe with very minor injuries. The cars had significant damage but were drivable, and there were no airbags out. These two accidents occurred within 3 to 5 minutes at the "SAME LOCATION." When I asked them what happened, my daughter and other Model Y drivers described a sudden loss of control, with their cars spinning and becoming unresponsive to steering and braking. They then hit the guardrail on the center line. I checked the video recordings of our car multiple times; no vehicle-to-vehicle collision was involved. …
I am reporting a safety concern involving a Tesla operating with Full Self-Driving Supervised active. On June 5, 2026, at approximately 7:50-7:55 AM Pacific Time, the vehicle was being driven with FSD Supervised engaged. The vehicle was in a turning maneuver when the driver mistakenly applied the accelerator. Vehicle data provided by Tesla appears to show ACTIVE_FSD shortly before the incident, a turning/steering angle, accelerator-pedal input/override, FSD becoming unavailable, and then crash-related/braking/tire-pressure signals shortly afterward. I am not claiming the vehicle accelerated on its own. The data appears to show driver accelerator input. My concern is that while FSD Supervised was active and the vehicle was already turning, the system allowed a strong accelerator override that rapidly worsened the situation. …
A fatal crash occurred involving a 2023 Tesla Model 3. The vehicle departed the roadway, impacted a guardrail, struck a utility pole on the driver's side, rolled down an embankment, and came to rest upright. The crash resulted in catastrophic intrusion into the driver's compartment and a fatal injury to the driver. I am requesting that NHTSA investigate the crashworthiness and occupant protection performance of this vehicle, including the structural integrity of the occupant compartment, airbag deployment and effectiveness, and the performance of any advanced driver assistance systems, including collision warnings and automatic emergency braking. …
I have a group of individuals that are hacking all of my accounts and trying to steal my car. They first hacked my emails then my Tesla account and now they are actually on the Teslas computer system and have been in the vehicle accessing the screen. After they hacked the system and stopped updates the car started having a bunch of safety concerns and alerts.The breaks were not working and the vehicle would freely roll when full pressure was applied. The collision system in the car was not working properly. Thinking it was possibly going to be hit by another car it would avoid nothing and jerk me out of the lane and nothing was around at all potentially causing an accident. Then the collision system stopped working all together. The steering system would not communicate properly with the system and kept requesting to be reconfigured with the system. …
