2026 Tesla Model 3 Driver assistance Problems

When using Tesla's Full Self Driving (supervised) speed control is erratic and not subject to the driver's control, such as it would be when using adaptive cruise control. As a result, the available speed modes (sloth, chill, standard, hurry and Mad Max) can cause the vehicle to dangerously exceed speed limits and at times to drive well below the posted speed limit, causing confusion and frustration to following drivers. There is no reason why the software cannot be changed to a safer method that would permit the driver to select the speed at which the car will travel, i.e. the speed limit, similar to adaptive cruise control found in most modern vehicles. When the operator of a vehicle is not in charge of the vehicle's speed, this is inherently dangerous.

My Tesla was operating under FSD at 9pm on a dark country road. I was traveling at 45mph and vehicle randomly applied hard emergency braking and I had to take over. It appeared that the vehicle may have been responding to a dark oil stain or possibly a mailbox. Had another vehicle been closely behind me, there would’ve been a collision.

On August 26, 2026, at approximately 8:56 AM, I entered a public parking garage in Washington, DC. Full Self-Driving (Supervised) was engaged and controlling the vehicle during a reversing maneuver. I remained attentive to the vehicle's surroundings, including pedestrians and surrounding traffic. While reversing under FSD (Supervised), the vehicle's right rear corner collided with the corner of a stationary structural pillar in the parking garage. I did not command the vehicle to steer into the pillar. Upon becoming aware of the impact, I immediately applied the brake. There were no injuries. The collision resulted in damage to the right rear area of the vehicle. After the incident, I photographed and recorded the scene and vehicle damage and saved the available Tesla Dashcam footage. I also requested the vehicle data from Tesla. I am reporting this incident because the vehicle collided with a stationary structure while FSD (Supervised) was engaged and controlling the reversing maneuver. I do not know the specific technical cause of the incident. The vehicle and available recorded data can be made available for inspection upon request.

The vehicle is experiencing severe, unpredictable software and hardware regressions related to the Full Self-Driving (Supervised) system (v14.3.7, Software build 2026.21.5) that create an immediate, active traffic hazard and a high risk of rear-end collisions. Primary Safety Issues: 1. TRAFFIC STALLS UPON DISENGAGEMENT: When Full Self-Driving (FSD) is engaged, auxiliary sensors malfunction, causing the headlights to cycle on/off and windshield wipers to run at full speed in clear, dry, midday daylight. When attempting to manually disengage FSD to correct these malfunctioning systems, the vehicle fails to smoothly transition control. Instead, it triggers critical red flashing alert lights, sounds severe warning chimes, and initiates an immediate, aggressive brake application—stopping the vehicle dead in active, live traffic. 2. PHANTOM BRAKING: The vehicle routinely experiences sudden, severe, and unprovoked phantom braking events while driving at speed, without any forward obstacles or environmental hazards present. 3. STEERING INSTABILITY: When navigating parking lot entrances, the vehicle exhibits extreme "indecisive behavior," resulting in violent, rapid shaking of the steering wheel before completing the maneuver. Tesla customer service was formally notified of these dangerous system behaviors on August 14, 2026. A formal remote engineering log review has been requested from the manufacturer, as these sudden braking actions in active traffic pose an immediate threat to public safety.

After a recent Tesla software update, a mandatory Full Self-Driving disengagement feedback window appears every time I disengage FSD while the vehicle is still moving. The feedback window covers a large portion of the display with a black overlay, noticeable enough something popped up. There is no setting to disable it, dismiss it immediately, or postpone the response until the vehicle is stopped. I am required to select a disengagement reason before I can access the controls and information behind the overlay. While this window is displayed, I cannot properly view or control functions such as music and other touchscreen features behind the area. This is especially dangerous because it appears immediately after I take manual control from FSD—a moment when my full attention should be on the road and the vehicle. The system effectively requires me to look away from the road and interact with the touchscreen before I can make another needed adjustment. This occurs every time I disengage FSD and is consistently reproducible. This behavior began after software version FSD v14.3.3. My vehicle is a 2026 Model 3. The problem occurred everytime while traveling at any speed. I believe this mandatory, non-dismissible overlay creates a serious driver-distraction hazard by obstructing the center display and requiring touchscreen interaction while the vehicle is in motion. Tesla should allow the feedback request to be dismissed, delayed until the vehicle is parked, or disabled entirely.

Firstly, we were driving in the center lane on I-84W (three lanes), with Full Self Driving (FSD) at 55 mph. The car veered left on it owns (under FSD) into the center median with the front driver side of the vehicle struck the metal beam guardrail causing both air bags to deploy on the driver and left rear passenger sides. The car continued to move forward in the next 4-6 seconds under FSD (approximately 10-20 feet range) and then came to a complete stop with flashing warning screen asking driver to take over the steering wheel immediately.

Incident involving my 2026 Tesla Model 3 equipped with HW4 hardware and the latest FSD (Supervised) software. During a garage reverse maneuver performed under FSD supervision, the vehicle had sufficient time to assess the surrounding environment before initiating the maneuver. There were no pedestrians or moving obstacles nearby. An adjacent parked vehicle was present next to the intended reversing path. During the maneuver, the vehicle made initial contact with the adjacent vehicle. At no point did the vehicle provide any collision warning, alert, or indication that a collision had occurred. After the initial contact, the vehicle continued moving and a second impact occurred shortly afterward, resulting in additional damage. Immediately after the second impact, the driver intervened and took control of the vehicle to stop the maneuver, before further damage is caused. My main concerns are: 1. Why did FSD fail to identify the adjacent vehicle before the maneuver? 2. Why was no collision warning provided before or after the initial contact? 3. Why did the vehicle continue the reversing maneuver after the first impact instead of stopping till driver intervention? 4. What if is pediatrician who qualify ADA, children, elder was in the position of the adjacent vehicle, this failed sensing would cause imparable result. I would appreciate a technical review of this event and a detailed explanation of Tesla’s findings.

Lane keeping assistance turns on with every drive no matter how many times I set it to off. Where I live there are many potholes and poorly paved roads, along with poorly marked roads. As I am swerving around obstacles the car will fight the steering inputs I am giving it, trying to steer me back into whatever I was avoiding. This is a safety issue, and is not a problem on our older Tesla model 3 performance, as once that vehicle is set to off, it stays off. Now, as I start every drive I am navigating through a couple screens to turn off this "safety" feature.

Incident

Jul 1, 2026

The vehicle's Full Self-Driving (FSD) system was actively controlling the vehicle while executing a reverse maneuver into a residential garage — a routine the system had successfully performed on multiple prior occasions. During this session, the FSD system misjudged the maneuver and the vehicle struck the wall of the garage, causing damage. The failed component is the FSD software/sensor system. The vehicle is available for inspection upon request. Safety was put at risk because the system was in full control of vehicle movement in a confined space. The unexpected behavior did not provide sufficient time for the supervising driver to intervene before impact. No warning lamps or messages appeared prior to the failure. The system gave no indication it would behave differently from previous successful executions of the same maneuver. The incident has not yet been confirmed by a dealer or inspected by the manufacturer, though a vehicle incident data report has been requested from Tesla.

On February 5, 2026, at 12:21 PM PST, my 2026 Tesla Model 3 (Hardware 4) collided with a 5-inch wooden pillar while using the Autopark feature. The system failed to provide any audio chimes or visual warnings prior to the impact. I officially requested the driving logs from Tesla to investigate the cause of this failure, but Tesla refused to provide any logs or data. Furthermore, Tesla Service Center technicians insisted there were no hardware defects, effectively confirming that the collision was caused by a software/algorithmic failure of the Tesla Vision system to detect a stationary vertical object. Despite Tesla’s claim that the vehicle is "operating as designed," the system's inability to recognize common infrastructure and its failure to warn the driver constitutes a severe safety risk. This defect must be investigated to ensure the safety of the Hardware 4 autonomous platform, as the lack of proximity alerts could lead to far more serious accidents involving pedestrians or other obstacles.

The vehicle's FSD system malfunctioned and initiated an unintended reverse toward a closing garage door. To prevent a total-loss event (the door crushing the glass roof and trunk), I was forced to perform an emergency manual takeover. Due to the vehicle's position caused by the malfunction, I had to maneuver through a confined space, resulting in the side-scrape. I am filing this as a malfunction claim because the damage was a direct consequence of the car's autonomous failure
