Safety Issue: Defective interior cabin camera causes Tesla Full Self-Driving (FSD) to disengage abruptly and without adequate warning at freeway speeds. I am a [XXX] driver. I purchased FSD capability with this vehicle in December 2018. In October 2025, I had the FSD hardware upgrade (HW2.5 to HW3) installed at Tesla's Encinitas, CA service center (B.A.R. License [XXX] ). Within days, FSD would became completely unusable due to a recurring "Cabin camera unavailable — schedule service" alert that instantly disengages the system. The disengagement occurs on the freeway at highway speed, without meaningful advance warning. As a [XXX] driver, the sudden loud alarm and loss of assisted driving is genuinely alarming — it is not immediately clear in the moment whether the vehicle has lost power or experienced a critical failure. This is exactly the kind of dangerous situation driver assistance systems should prevent, not cause. Tesla's own diagnostic confirmed the defect (Diagnostic Invoice No. XXX, November 27, 2025, Encinitas service center): "Cabin camera unavailable" alert verified Intermittent stream exit faults detected in the selfie/cabin camera Low-voltage circuit and wiring checks were normal — ruling out wiring Conclusion: fault is within the camera module itself; technician recommended replacement The defect is FSD-specific. The cabin camera works correctly for Sentry Mode, live security viewing, and all normal driving. It fails exclusively when FSD is engaged and demands sustained driver monitoring. The camera housing also becomes extremely hot to the touch during FSD use, consistent with reports from other 2018 Model 3 owners describing identical symptoms after their HW3 retrofits.

When using FSD in "chill" mode the car attempted to cross over into oncoming lane on a two lane highway. There were no oncoming cars and I overrode the car almost immediately. The car has not been inspected by anybody. No warning light, messages or other symptoms. I have a video of the incident for a Viofo dashcam installed in the car.

I am submitting this report to the National Highway Traffic Safety Administration regarding a recurring safety issue with my 2018 Tesla Model 3 involving unintended “phantom braking.” On multiple occasions, my vehicle has abruptly decelerated without any apparent obstacle or hazard present. These incidents have primarily occurred while using driver assistance features such as Autopilot and Traffic-Aware Cruise Control on highways and well-marked roads under normal driving conditions (clear weather, dry pavement, consistent traffic flow). The braking events are sudden and significant, creating a serious safety risk—particularly when other vehicles are following closely. In several instances, the deceleration was forceful enough that I believed a rear-end collision was likely. There were no visible triggers such as overpasses, shadows, vehicles merging, or roadside objects that would reasonably justify the system’s response. Below are details to assist your investigation: •Driver Assistance Features Active: Just cruise control, not auto pilot on these occasions •Weather/Road Conditions: Clear and dry •Frequency of Occurrence: This is an ongoing problem that has occurred dozens of times in the past few years. The March 30th incidents were only the most recent ones. •Any Warning Messages or Alerts: No This behavior appears unpredictable and difficult to anticipate or mitigate, increasing the risk of a crash. Given the potential safety implications, I respectfully request that NHTSA review this issue to determine whether it reflects a broader defect affecting other vehicles. Thank you for your attention to this matter.

I was driving with Full Self Driving active on Sunday morning and my car came to a complete stop at a red light. Once the traffic cleared the car drove right through the red light and I was given a traffic citation by a police officer. The car did wait until there were no other cars present so I don't believe I was in any real danger but the fact that the car went through a red light while on full self driving violates the rules of the road which as we know is illegal. I have a video from my dash cam but this form doesn't appear to allow for video uploads.

There is no checkbox for Full Self Driving (Supervised): 3 times in the last 4 weeks, my Tesla has become impatient at long red lights and lurches out into the intersection. I am very concerned because one of those times (first time) it did not creep forward, but just took off thru the red light. I had to accelerate thru to get ahead of those cars that still had the green light. Fortunately, nothing untoward happened, except scaring me! The other two times, I recognized what was happening and put on the brakes and removed from FSD mode. I have complained to Tesla and am asking for them to verify my FSD is up to date and this issue will be fixed. Needless to say, I have stopped using the FSD (Supervised) until this is all addressed.

Description of the Defect: While driving with Full Self-Driving (FSD) engaged, the vehicle's primary computer shuts down and reboots, causing a sudden loss of all safety features, including Blind Spot Monitoring, Lane Departure Warning, Forward Collision Warning, and the driving visualization. The cameras go black while the vehicle is in motion. The Trigger: The failure is triggered by high electrical load. If the Cabin Heater (HVAC) and Seat Heaters are active while FSD is fully computing, the 12V power supply to the computer drops below critical voltage, causing a "Turbo A" processor lockup and system crash. Evidence of Defect: Service Center diagnostics confirmed the specific error code APS_w169_TurboA_SCS_LKUP (Computer Crash) occurred at the exact same timestamp as VCLEFT_a302_blowerGeneralFault (HVAC Blower Failure). This proves a common-mode voltage drop affecting multiple critical systems simultaneously. Manufacturer Response: The manufacturer (Tesla) acknowledged the logs but refused to inspect the wiring harness or ground connections, instead recommending a replacement of the computer unit. However, the failure can be mitigated by unplugging external cameras to reduce load, proving the root cause is an insufficient power delivery design (Wiring/Grounding) rather than a component failure. The computer is running at full load with the newest FSD software and it can no longer keep up with additional loads. Safety Risk: This defect causes a sudden, uncommanded loss of driver assistance and situational awareness tools (cameras/visualization) while the vehicle is maneuvering in traffic. The vehicle’s power distribution system appears insufficient to support the electrical load of the software (FSD) and the hardware (HVAC) simultaneously.

I am reporting a major safety defect that began immediately after Tesla installed the Full Self-Driving (FSD) hardware upgrade on my vehicle. After paying $2,000 for FSD and receiving the hardware retrofit, the car now instantly veers left toward oncoming traffic whenever FSD is engaged. This began immediately after Tesla’s installation. Before this service, my vehicle operated safely. I have contacted Tesla Cherry Hill Service Center in New Jersey multiple times. The advisors there repeatedly told me to “just recalibrate the cameras from the touchscreen.” I’ve done this numerous times, following every instruction carefully, but the issue persists. When I called the Service Center, I was told that “everything looks fine remotely,” even though the problem continues and is clearly dangerous. I was also told they could take it for a test drive, but that if they couldn’t find anything, I would have to “wait for a future update” to make FSD usable. This is unacceptable and unsafe. Tesla delivered this car to me in a dangerous condition that could easily cause a serious crash. A car that steers itself into oncoming traffic under FSD control should never have been returned to a customer — especially one new to using FSD. I should not be responsible for any repairs, recalibrations, or diagnostics related to a defect introduced by Tesla. This issue appears to be the direct result of improper installation, misalignment, or faulty calibration following the FSD hardware upgrade performed by Tesla Cherry Hill. This poses a severe risk of collision and injury, and Tesla’s refusal to take responsibility or correct it under warranty demonstrates clear negligence and disregard for safety. Tesla Cherry Hill is also known for poor customer service and repeated dismissal of safety complaints from other owners, which further concerns me.

Repeatedly and randomly, with cruise control (not FSD) engaged, the car would brake, sometimes aggressively. The last time, it braked so hard the tires or brakes squealed and the car swerved slightly before I was able to regain control. This was on the freeway (in Colorado, if I remember correctly) while I was cruising at 70 or 75 MPH. I decided that that was the last time I would use cruise control; it was just not safe. I had an appointment on October 22 to take the car in for service. But then a friend told me this was called "phantom braking" and that there was no fix. A friend suggested that I contact the NHTSA.

Main incident: Time: 2025-08-28 ~12:41 PM PST What happened: After searching for a parking space, the driver was preparing to reverse into the spot, the driver pressed up the stalk to shift the gear into reverse, a sound was heard and something showed up on the screen, the vehicle once again started accelerating and running forward suddenly and sharply (3 mph to 28 mph in 3 secs), driver tried to steer the vehicle away from cars and buildings to minimize danger, the car rushed onto a concrete curb, hit one blue Tesla, then hit the side of a concrete utility pole, and ran over a plant and last crashed into the chain-link french before it finally stops Injuries: * Spine pain for one passenger Damages: ** All tires blown out, tire falls off ** Severe damages throughout the vehicle body * One Tesla parked on the parking lot was severely damaged * The utility pole's base box was scraped and deformed * One plant was knocked down Similar case 3 few mins ago: Time: 2025-08-28 ~12:38 PM PST What happened: The driver entered a oneway parking lot, but found no available spot and was trying to back up, the vehicle suddenly accelerated on its own. The driver performed an emergency brake and stopped the vehicle. At the time the vehicle stopped, it was only about 20 inches away from two cars in front of it Injuries and damages: None What component or system failed or malfunctioned, and is it available for inspection upon request? Malfunctioning of the electronic control or braking system leading to abnormal acceleration Conflicting gear shifting and autopilot engagement design The right stalk is used to both shift gears and engage autopilot features, this design makes it very easy for the system to confuse the two actions Autopilot feature safety issues Autopilot features (whether its FSD or cruise control) should not be allowed to initiate abrupt acceleration to a dangerous speed in a low speed area (for example parking lot) Insurance claim filed, number: 25-647243342

Backup camera recall was not fixed properly or the new parts have same issue. As a result the backup camera was not functioning. When the camera is not functioning the autopilot system drives aggressively, speeding up to the max set speed when it is not safe to do so with current traffic conditions. Had to disengage autopilot otherwise it would have crashed. Also I received an alert that the emergency breaking system was not functional. When reversing could not use backup camera.

Front suspension creaking & rattling going over bumps Tesla took days & days & never called me w/ problem I kept calling in!! Finally decide it is a KNOWN recall problem w/ Suspension bolts & sub frame! They told me they torqued them & would test drive for noise & I never heard from them! I had to call in. Suddenly I had a $4200 estimate for repairs including $322 1.24 hours of diagnosis??? A known problem other 2018 Tesla’s have been recalled for ??? Very suspicious?? How do I know they didn’t torque it too far & strip bolt themselves??

October 12, 2024. I was using the Tesla on autopilot. I was in the far right lane and the freeway was curving to the left. The car was following in the lanes, but then all of a sudden it stopped following the freeway and drove into the right guardrail. There were no alerts by the car. It did not warn to take over the vehicle or attempt to avoid the collision. The car drove directly into the guardrail without warning and was totalled.

Tesla 3 was self parking backwards and failed to stop when the car in the adjacent parking spot started moving. The result was a small scratch, but this is definitely a bug in Tesla self-parking software: it had to stop when another car moves into the stop Tesal selected for self-parking.

I was at a stoplight behind a Toyota Tacoma. I must have stopped around 8 feet behind it. I was not using FSD and I was not one-pedal driving. My foot was on the brake. I must have been at a complete stop for approximately 10 seconds when my Model 3 suddenly accelerated full throttle on its own and rear ended the Tacoma, directly hitting its trailer hitch, causing my car's driver-side airbags to deploy. When it happened, the light was still red and my foot was still on the brake. I never touched the accelerator. Luckily I was driving alone. After the inital contact, my car sort of bounced off of his hitch then slowly lurched forward before it stopped. After that, it was immobile, leaving me stuck in traffic until it was towed away.

On December 24, 2024 I was driving on Freeway 5 South and all of the sudden my vehicle came to an abrupt breaking without any reason. The traffic ahead of me was of normal traffic. This abrupt breaking happened twice within 5 minutes of time span. I have notified Tesla Service Center and the service center gave me a quote of $137.50 for diagnostic and to schedule the service. I felt that this issues should be taken care of by Tesla with no charge to me. This is a safety issue. I have experienced the abrupt breaking issues with my vehicle on many occasions since I own the vehicle in 2018. Each time I was told there's no problem with the vehicle when I notified Tesla Service Center.

I’m not exactly sure what’s wrong, the screen keeps failing on my car. It’s been taken to Tesla to service this issue 4 times. With the most expensive repair costing $2,200. Its poses a safety hazard because when the screen fails. You can’t see anything, speed, gear. You can’t adjust windshield wipers, seat or mirror positions.

Two incidents while testing the most recent version of Tesla's "Full Self-Driving": 1. While driving at less than 25mph in a residential neighborhood, using the "Full Self-Driving" mode, the car was entirely unable to detect either heavy steel plates in the road (being used to cover road work) or significant potholes in the area near the plates. 2. While driving on H1 (a federal "interstate" highway) on Oahu, at approximately 55mph, using the Tesla's "Full Self-Driving", the car inexplicably slammed on the brakes. There was absolutely nothing visibly in front of the car for at least 200 yards. The car behind me had to swerve to avoid rear-ending my vehicle.
