Driver Assist & Collision Avoidance across every Tesla Model 3 year
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. The power train system kept throwing alerts. The tire pressure sensors stopped working and will not retrain now. They keep stopping the software updates now and have an IT admin portal device management program on the system and have complete control of the car’s system. Recently they were checking into enrolling in to fleet developer API to interact with the vehicle at code level. I have tried everything to get them off the account and they live at my apartment building. They are using illegal hacking tools and devices to gain access spyware and malware on all my devices.Tesla has done little to nothing to fix this problem and reports have been made. This is a major safety concern.

BACK OVER PREVENTION: WARNINGS
Im using full self driving (fsd) and it scans the lot and chose to pull into an empty spot half way in and reverse almost smacking a car in the rear. It didnt appear it was gonna stop even though the car was showing on the screen. I do have the dash cam from where i had to step on the break for it to disengage.

I was driving with plenty of distance between me and the car in front of me. The car in front of me had stopped and the Automatic Emergency Braking System on my car went on. Thankfully, there was no car behind me, otherwise, I would have been hit. The sudden stopping has caused me significant lower back pain.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
On XXX at around 3:30 PM EST, I was driving my 2023 Tesla Model 3 on [XXX] about 10 miles outside of [XXX]. I had the adaptive cruise control set at 75 mph. I was driving in the right lane of the two available lanes of travel in that direction. I noticed an unattended car on the right shoulder about a 1/4 mile up the road and continued my drive as normal. The car was at least 5' to 6' off the highway. As i got about 30 yards from the car, my car suddenly slammed on the brakes automatically, which forced me to react in a corrective manner. Thankfully there was nobody behind me or the severity of the braking would have likely caused a rear end collision. To my understanding, this phantom braking is a known issue with Teslas, so I wanted to document my experience to add to the record.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
On 8/24/2026 at approximately 12:02pm, my 2023 Model 3 was parked in my assigned space in a covered apartment carport, with a concrete support pillar approximately one to two feet from the passenger side. I entered a destination and activated FSD (Supervised) from Park, a Tesla-designed feature. Vehicle telemetry recorded in the dashcam clips shows FSD shifted into Drive, activated the right turn signal, turned the steering wheel to near full right lock, and accelerated to 3 mph, contacting the pillar with the passenger mirror and front door approximately 1.5 seconds after first movement. No accelerator or brake input was recorded from me before the collision. I applied the brake within one second of the impact beginning, and FSD disengaged. The pillar was within view of the vehicle's side cameras throughout. No warning was given. Damage to the passenger door; no injuries. Dashcam video with telemetry overlay and photos available.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Two separate incidents occurred on July 10th and July 12th 2026 involving adaptive cruise control. While adaptive cruise control was engaged my car slammed on the brakes for no reason. There was nothing in the roadway to cause abrupt braking. The second time it occurred my car was close to being rear ended by a vehicle driving behind me. I took the car which is still under warranty to Tesla who confirmed there is a known firmware issue. No time frame was provided as to when the issue will be fixed.

Roscoe, IL
FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Whilst driving on highways which feature multiple speed limits - eg. 70 cars, 65 Trucks, 60 Buses. If full self driving more or when in adaptive cruise control - the car systems fail to recognize the restriction linked to the lower speed limits. As a result, you can be driving on Full Self Drive at 75mpm, the car sees a 65 followed by a 60 speed limit (neither applicable to cars), but the car brakes hard dropping the speed from 75 to 62 almost instantly and, on more than one occasion, a closely following car has almost collided with me. Until such time as the Tesla system can recognize the 'sub text' on a speed limit - the FSD and Adaptive cruise should not be certified. I also drive a BMW i4 and this reads all signs correctly, only applying those applicable to a car to the vehicle.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
My 2023 Tesla Model 3 (VIN [XXX]) has a recurring safety defect in its driver-assistance system involving two unsafe behaviors. First, “phantom braking”: while driving with Autopilot/FSD engaged, the vehicle decelerates suddenly and without warning when there is no obstacle or threat in its path, creating a rear-end collision risk. This was first reported within the vehicle’s warranty period and has recurred. Second, on the most recent occurrence, with a Tesla service technician riding along to witness the issue, Full Self Driving (Supervised) failed to proceed safely through the intersection of [XXX] and [XXX]. The vehicle stopped mid-turn while another vehicle approached from the opposite direction. I had to take manual control to complete the turn and avoid a hazard. The Tesla technician witnessed this directly, and the service summary states FSD “did not proceed through the intersection properly.” The vehicle has been to a Tesla service center twice for this defect. It has not been resolved. The behavior occurs without warning and is unpredictable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FORWARD COLLISION AVOIDANCE: WARNINGS
I was driving today in California, to TopGolf. I had to cross a railway crossing around [XXX] I think, or [XXX] - one of those 2, between [XXX] and [XXX] pm.. I was using Tesla's FSD driving to go on a local road. I was not distracted or occupied - the vehicle was going at a fairly high speed like maybe 35 or so, and in a couple of seconds, it broke the red and white safety gate at a railway crossing, inspite of it being down and the train being on the tracks - I WAS IN SHOCK. The car completely missed the red and white gate, and just blew past it, damaging my windshield completely to smithereens and throwing glass all over the car. I was in such SHOCK and TRAUMA that I literaly wanted to exit the car and sit down somewhere, but i gathered my composure and drove quickly to the nearest safest place I could stop, and got into some office parking garage. I then called the cops and reported it. This was such a shock, and thank the Almighty God that I wasnt hurt and that the train didn't just hit me. This HAS to be recalled, and there is no way this should be allowed on the roads. I used FSD a Lot and i will never use it again.

NHTSA complaint #11746850 — an unverified report by a vehicle owner.
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 am also requesting review and preservation of all available vehicle data, including Event Data Recorder (EDR) information, vehicle telemetry, driver assistance system status, warning notifications, braking data, steering data, and any other information recorded before and during the crash. At this time, I do not know whether a vehicle defect or system malfunction occurred. My concern is whether the vehicle’s safety systems and occupant protection systems functioned as intended and whether additional vehicle data may help determine if any safety-related issues contributed to the severity of the crash.
NHTSA complaint #11746034 — an unverified report by a vehicle owner.
The vehicle was purchased pre-owned directly from Tesla. On the day of pickup and five days later, while operating on Full Self-Driving (FSD), the vehicle phantom-braked abruptly and then dangerously accelerated through a solid red light into cross-traffic intersections. The driver had to forcefully override the vehicle to prevent a crash. Tesla Service Center was notified but dismissed the issue, performing only a camera recalibration and charging a fee. Following the service appointment, the red-light running behavior stopped, but the vehicle continues to suffer from aggressive, sudden phantom braking multiple times on every single trip, creating a severe and continuous risk of a rear-end collision on public highways.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
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. In this case, the vehicle went over a curb/sidewalk area and sustained significant damage. The safety concern I am reporting is whether FSD Supervised should better limit, warn, or manage strong accelerator override during low-speed turning maneuvers, especially where the vehicle may leave the roadway, cross a curb, or enter a sidewalk area. I believe this involved driver error as a mistake pedal acceleration, but the system design may have allowed that error to create a more dangerous outcome.

NHTSA complaint #11738836 — an unverified report by a vehicle owner.
While driving at highway speed under normal operating conditions with the accelerator engaged and no braking input, the vehicle suddenly experienced a sustained 6-minute-12-second ADAS/EDR degradation cascade. This included OVERHEAT_PROTECT_FANONLY activation, repeated AEB_CAN_STATE_UNAVAILABLE toggling, FAULT 14.0 brake-signal mismatch, impossible negative brake pressures, and 27+ ABS/EBD/ESP fault-lamp cycles. No warning lamps, messages, or alerts appeared prior to the cascade. The degradation resulted in loss of braking assist and stability control functions, causing two collision events (right-side T-bone impact followed by curb strike) despite no driver error or input. This failure mode matches the exact ADAS/EDR degradation pattern under active NHTSA Engineering Analysis EA26002. Full technical details, timestamps, fault logs, sampling gaps, and EDR data are provided in the attached narrative PDF and supporting CSV files.

South Bend, IN
FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
The Full Self Driving (Supervised) system (FSD(S)) failed by running a red light. Video is available for inspection upon request. My safety was not at risk - this time - because the system waited until there was no cross traffic to resume motion, even though the light was still red. I have not tried to reproduce the problem for a dealer since it happens infrequently. (This is the third time in perhaps 6 months of subscription to TESLA's FSD(S). TESLA has not informed me of any inspections they have performed, even though they have been notified through the channel they provide. There was no indication from the car that it perceived any failure. It stopped only when I applied the brake. Prior symptoms include two previous incidents of stopping for a red traffic light, waiting until there was no cross traffic, then resuming motion while the traffic light was red. This is the first time I thought to save dash cam video.
NHTSA complaint #11726564 — an unverified report by a vehicle owner.
An incident that occurred while Full Self-Driving (FSD) was engaged. During the drive, the vehicle unexpectedly steered toward the curb while making a right turn. I was actively monitoring the vehicle and immediately took control of the steering, but the vehicle still made contact with the curb. After the incident, the vehicle developed steering misalignment, vibration while driving, and abnormal noise, which suggests possible suspension or wheel damage. Since FSD was engaged at the time, I would appreciate it if Tesla could review the vehicle logs and investigate whether there was any system malfunction or unexpected behavior from the FSD system.

On August 7th, 2025 at around 8 AM in the morning, my vehicles mobile phone car key was in-operable and I was unable to get in the car which led me to trouble shoot how to fix this issue with the car. Upon researching I was directed by Tesla to directly complete a soft reset of the vehicle holding down both buttons on the vehicle once I was inside, and pushing on the brake pedal. Upon completion, my vehicle booted up and I realized that all camera systems were down, my navigation systems were down, my safety features were down, my auto pilot, lane keeping assist and auto brake were down, sensors were down and I was no longer able to pre heat my battery to charge my vehicle due to issues with the navigation. I then took the vehicle to Tesla Service Center Irvine where a service advisor quoted me 2900 for a new ECU and Bolts and told me that I needed to replace my whole unit and that I was to cover the cost of the repair even though my vehicle is only 2 years of age and this failure is due to the quality control and software of the vehicle. I have been driving around a vehicle with absolutely no safety features whatsoever such as no cameras, sensors, auto braking, or full self driving due to this ECU failure and I fear for my safety and well being while driving this car.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
While driving my Tesla equipped with Autopilot/Traffic-Aware Cruise Control, I experienced an unexpected and abrupt braking event. A vehicle had entered the center turn lane and had already cleared my lane, posing no obstruction to my path. Despite this, my Tesla suddenly applied the brakes without warning, causing a rapid deceleration that could have led to a rear-end collision had another vehicle been following closely. There were no visible hazards, warning messages, or alerts prior to the braking. The incident occurred in clear daylight conditions on a dry road, and the vehicle in the center turn lane was stationary or turning away from my lane. This appears to be a case of phantom braking, possibly due to misclassification of the adjacent vehicle or overcautious object detection by the vehicle’s Advanced Driver Assistance Systems (ADAS). This issue has occurred more than once in similar scenarios, and I believe it poses a serious safety risk. I have not yet had the issue inspected by Tesla or a service center, but I am submitting this report to raise awareness and request investigation into the reliability of Tesla’s braking logic in these situations.
