I and others have noticed that once UNsubscribed from FSD, lane departure alerts and automatic corrections occur much more often than when subscribed to FSD, even if car is being driven by user. The alerts and corrections happen on almost every drive despite being within normal lane spacing. It feels like this is intentional to push users to subscribe back to FSD. Driving other makes of vehicles does not result in nearly this amount of warnings and corrections. Various online forum post corroborate this behavior. Even if there is an explained reason for it, Tesla does not notify the user of such changes that will happen once unsubscribing from FSD.

I am reporting an issue with Supervised FSD regarding school zones in Ohio. In my area, active school zones are indicated by flashing lights. The FSD system successfully recognizes these lights and reduces the vehicle's speed to the legal limit of 20 mph. However, if there is a traffic light within the school zone, the vehicle loses track of the school zone speed limit after stopping or cycling through the intersection (red/green transitions). Once the traffic light turns green, the car quickly accelerates back to the normal speed limit (e.g., 35 mph) while still inside the active school zone. I have posted this issue to @Tesla and @Tesla_AI on X, but have not received a response.

I am reporting a safety‑critical issue with the automatic windshield wiper system on my 2024 Tesla Model Y. The vehicle uses a camera‑based “Auto Wiper” system, and it consistently fails to activate fast enough during heavy rain, spray from passing trucks, or sudden visibility loss. During moderate to heavy rain, the Auto wipers often stay on a slow or intermittent setting even when the windshield becomes fully covered with water. The system does not increase wiping speed quickly enough to maintain visibility. This results in several seconds where I cannot clearly see the road ahead. This problem is made worse because the Model Y makes it difficult to quickly switch to manual wiper control while driving on the freeway. The driver must look down at the touchscreen and navigate menus to adjust wiper speed, which is unsafe at highway speeds. The delay between losing visibility and being able to manually increase the wiper speed creates a dangerous situation. This behavior has occurred multiple times at highway speeds. When passing large trucks or encountering sudden water spray, the wipers do not react, and the windshield becomes momentarily opaque. This creates a serious risk of losing lane position or failing to see vehicles in front of me. This is a safety hazard because: 1.The Auto wipers do not clear the windshield when visibility is urgently needed. 2.Manual override requires taking eyes off the road to use the touchscreen. 3.The delay in response can lead to loss of visibility for several seconds. I am requesting that NHTSA investigate this issue, as it affects visibility and could lead to collisions, especially at highway speeds or during sudden heavy rain.

Component or system that failed: The GPS navigation system and cellular connectivity module in my 2024 Tesla Model Y (VIN: [XXX] ) have intermittently lost signal and become completely nonfunctional multiple times over the past month. Tesla's service documentation indicates this affects the vehicle's connectivity hardware or managing software. The vehicle is available for inspection upon request. Safety risk: Loss of GPS navigation while driving creates a safety hazard when traveling unfamiliar routes, in low-visibility conditions, or during emergencies. Loss of cellular connectivity simultaneously disables Tesla's roadside assistance and the vehicle's calling capability. The vehicle acknowledges this risk by displaying a yellow caution alert reading "Poor GPS location accuracy — Additional attention may be required" on the primary touchscreen while in motion, with no advance warning before the failure occurs. Reproduced or confirmed by a dealer or service center: Yes. On May 22, 2026, Tesla Service Columbia-Two Notch Rd, 6301 Two Notch Road, Columbia, SC 29223, confirmed this as a known issue. The service advisor stated Tesla is aware of the defect but has no repair available and instructed me to submit in-car bug reports each time it occurs. Inspected by manufacturer or others: Yes, by Tesla's service center on May 22, 2026. No independent, police, or insurance inspection has been performed. Warning lamps or prior symptoms: A yellow triangle caution icon with the message "Poor GPS location accuracy — Additional attention may be required" appears on the primary touchscreen during each failure, but only after GPS has already degraded — no advance warning is given. This has occurred four times since April 2026, with each event lasting between 15 seconds and over one minute. UNKNOWN as to specific trigger conditions. Photographic documentation has been retained.

I am reporting a software-induced driver distraction defect in Tesla’s Full Self-Driving (Supervised) system, specifically the post-disengagement “Why did you intervene?” dialog introduced in software 2026.2.9.8 and modified in 2026.2.9.9 and 2026.2.9.10, running FSD v14.3.2. Every time the driver disengages FSD via steering, brake, or accelerator input, a modal dialog appears on the center touchscreen asking the driver to categorize the intervention. It presents four options (Navigation, Preference, Discomfort, Critical) plus a voice memo prompt. The dialog cannot be dismissed or deferred. It remains on screen indefinitely until the driver reads the prompt and taps a selection. This creates a serious safety hazard: The dialog appears the moment the driver has resumed manual control, often in response to an unsafe FSD action requiring immediate attention to the road. Forcing the driver to read text and make a multi-choice touchscreen selection during this high-cognitive-load transition directly conflicts with NHTSA’s Driver Distraction Guidelines for in-vehicle devices. The dialog occupies a large portion of the center display and obscures the navigation map and surrounding-vehicle visualization, removing situational awareness at the moment it is most needed. Because it cannot be dismissed, drivers are coerced into touchscreen interaction while driving, including in active traffic, intersections, merges, and lane changes. The forced-choice design also incentivizes drivers to tap any option to clear the screen, defeating the stated data-collection purpose and increasing eyes-off-road time. Tesla provides no setting to disable this dialog. I request NHTSA investigate this as a driver distraction defect and require Tesla to provide a dismiss option, defer the prompt until Park, or remove the forced-interaction requirement. I am the vehicle owner and experience this on every FSD disengagement.
