For over the past 18 months, Tesla FSD software deliberately removed the driver’s ability to control following distance, instead replacing it with fuzzy descriptions of “mad max, hurry, standard, chill, and sloth.” As a result the car cannot maintain a safe highway following distance as determined by the driver. When in Hurry and or Standard mode, the car will routinely reach speeds of 75 to 80 mph and decrease following distance to about 3 car lengths, with no car for more than 20 car lengths behind. When a sudden slowdown occurs, the tesla reacts slowly, often decreasing the following distance to 1 car length, as the car behind closes and misjudges the deceleration of the Tesla, resulting in a potential 3 car collision. Adjusting from hurry to standard, or even down to chill or sloth mode does not bring the following distance back to the driver’s education rule of thumb - 1 car length per 10 mph. About 3-10 seconds after the mode change, the software forces an unexpected lane change into a slower lane. The only solution is to disable all driver assistance measures, coast to the necessary following distance and then re-engage. The cycle then repeats. Sometimes when there are nearby cars blocking lane changes, the car remains at 1 car length following distance (for up to 7 seconds after changing from hurry to sloth mode), with the car behind at 3 car lengths while remaining at 70 to 75 mph. Software versions include the latest: 2026.21.6, with the HW4 autopilot computer. This is completely a vendor chosen software defect which could easily be addressed by new defaults, or with simple software changes. The elegant solution is to use the autopilot control scroll wheel. Presently, it takes 2 “detents” to change between modes, if turning one detent downwards would allow driver to increase following distance, that would be sufficient. Alternatively within the Byzantine onscreen menus, an option could be added, but that would be unsafe to adjust while driving.

In April 13th, 2026 while driving from the house through community, I suddenly stopped at the cross roads due to unexpected conditions. During this event, a coffee mug placed in the cup holder tipped over and spilled liquid onto the center console area—near the phone charging pad and critical control panel used for gear selection and essential driving functions. In about 15 minutes after the spill, when I reached the highway at about 70 mph, the vehicle experienced a rapid and severe system-wide failure. The dashboard displayed multiple warnings and errors, including: * “Steering assist reduced – Steering may require increased effort” * “Center console buttons to select gears unavailable – Use touchscreen to select gears – Schedule service” * Repeated alerts indicating braking and system limitations * Conflicting and inaccurate readings, including the speedometer displaying “0 mph” while the vehicle was still moving at highway speed At the same time: * Braking response was severely compromised despite full pedal application * Hazard lights and turn signals were non-functional * Gear selection controls became unavailable or unreliable * Driver assistance and safety systems were disabled * The system issued instructions to “press and hold brake” while braking performance was inconsistent This resulted in a complete loss of situational awareness and control while I was in the car with my older parents and my child. l. I was unable to signal to surrounding vehicles while attempting to maneuver into a narrow emergency lane at highway speed. My family and I had fear for our lives. Critically, the vehicle instructed to exit immediately while we were still in a dangerous roadside position without functioning hazard lights. We were exposed to active highway traffic without any ability to alert others. was eventually able to maneuver the vehicle into the emergency lane under extremely dangerous conditions. The vehicle was towed, and the issue was reported immediately.

In January my parents Tesla in self driving mode drove them straight through a building. The breaks didn't deploy, the airbags didn't deploy and the steering wheel was shaking and unresponsive. Thankfully no one was seriously injured. That said, there was a lot of physical damage to the restaurant/building and the car was completely totaled. We are certain that there were catastrophic failures with the car that caused the accident however the mechanic has informed us that due to her NDA she cannot provide any details about her findings after examining the car. She sent her findings to Tesla who was supposed to issue a report to us and the insurance company, but several months later we still have not received anything. They are well past the 30 days time limit. We cannot get anyone from Tesla to respond to us. There was a police report and the cops, firemen, and mechanics where all absolutely floored that the airbags didn't deploy given the damage to the vehicle. Self driving failed. Breaks failed. Steering failed. Airbags failed. and Tesla has failed to respond.

On April 1st 2026, our brand-new 2026 Tesla Model X, 6-seat configuration, experienced a dangerous third-row seat incident. Our dog slipped into a blind spot beneath/behind the third-row seat while the seat was folded down. After the dog became trapped, the powered third-row seat would not respond, and there was no usable manual release or mechanical way for us to raise the seat and free him. The dog was trapped under the seat and in immediate danger. We drove directly to Tesla Service for an emergency rescue. Tesla personnel informed us that the only way to free the trapped animal was to dismantle and destroy/remove the rear seat assembly. That is what they did. The dog was then taken for emergency veterinary treatment and remains traumatized, with possible physical injury. This vehicle had been delivered only 4 days earlier. In my view, this presents a serious safety/design issue involving the third-row power seat system and the lack of an accessible emergency release when a living occupant or animal is trapped under the seat. The fact that destructive disassembly was allegedly the only way to free the trapped animal raises a serious safety concern. I am requesting that NHTSA review this incident as a potential safety defect involving the third-row seat mechanism, emergency release/access, and occupant/animal entrapment risk. I have photos, veterinary records, and related documentation.
