2024 Tesla Cybertruck Lane departure Problems

“On December 23, 2025, at approximately 9:45 AM, I was operating my Tesla Cybertruck with Autopilot engaged under normal driving conditions. There was no inclement weather, the roadway was straight, and visibility was clear. While driving, the vehicle suddenly veered off the main roadway without warning and traveled off-road, ultimately colliding with a tree. The movement was abrupt and not consistent with normal lane departure. …”

“This is reporting an issue with v14.3.3 and v14.3.4 of Tesla Full Self Driving (FSD) Supervised. This month I have driven over 4,000 miles with FSD enabled, approximately 2/3rd on 14.3.3 and 1/3 on 14.3.4. FSD has regularly failed to respect speed limit changes, even though it seems to recognize / observe the speed limit signs. I am certain it’s observing the signs because it renders them on the in-car display, but it doesn’t actually adjust its speed in response to those signs. …”

“I am filing this complaint regarding Tesla's failure to include the advertised Autosteer feature in my new Cybertruck, which I believe raises serious safety concerns. At the time I ordered my vehicle, Tesla's website and the official Cybertruck Owner’s Manual (archived October 15, 2024) clearly listed Autosteer as a feature included with Autopilot. Tesla also markets Autopilot as a system that “enhances safety and convenience,” which formed a core part of my purchasing decision. …”

“While driving with Tesla's Full Self-Driving (FSD) system engaged, my vehicle struck two standard traffic cones in a clearly marked construction zone. The system failed to detect the cones or make any evasive action. I have video evidence of the incident. The situation was extremely dangerous. The cones could easily have been construction workers, pedestrians, or something more severe. I hesitated to intervene because it happened in a split second, and I was trusting the system to respond — which it completely failed to do. …”

“Approximately 10 minutes after my vehicle was serviced at a Tesla Service Center for a Full Self-Driving (FSD) concern, I entered the highway and engaged FSD. The service center had stated the system was operating correctly. While traveling approximately 75 mph through a highway curve, FSD suddenly changed to an Unavailable state. According to Tesla's own accident data, I did not disengage FSD. There was no audible warning, no effective visual warning, no takeover request, no controlled deceleration, and no safe handoff to the driver before the vehicle stopped controlling itself. …”
