Assist problems of the 2023 Tesla Model X

The primary issues are: the vehicle consistently chooses the wrong lane and drifts across yellow lines. The fsd visualization fails to correctly distinguish road markings, lanes, and turning arrows, causing them to move erratically on the display. The car attempts to merge into lanes that appear in the visualization but do not exist on the road. The vehicle attempts to merge into lanes that are ending, without recognizing the lane-ending markers. My service history for this single, unresolved issue is as follows: June 12, 2025 (invoice #3000s0013397552): I brought the vehicle in because autopilot was incorrectly detecting lanes. The service team diagnosed "severe hazing over forward facing cameras," cleaned them, and returned the car to me. The problem was not fixed. July 1, 2025 (invoice #3000s0013588350): I returned for the same issue, stating that the fsd was driving over yellow lines and not recognizing traffic patterns. The diagnosis was changed to a bad alignment; service notes indicate "multiple angles out of specification". A four-wheel alignment was performed, and I was assured the issue was resolved. July 10, 2025 (invoice #3000s0013675264): on my third visit for this issue, the service team verified that the autopilot visualization showed "random turn lane markings". However, I was told this behavior was "considered normal at this time" and would improve with future firmware updates. The "correction" was listed as "remote - education". July 28, 2025 (invoice #3000s0013834479): I returned for a fourth time, explaining that the problems persisted and were a safety concern. I noted that the car had recently tried to merge past a solid yellow line into the shoulder. The service team acknowledged the issue but concluded it is an "issue with v13 due its design" and that "no repairs are recommended for this concern". The assertion that this is a "known characteristic" is unacceptable. The fsd and autopilot features are now unusable and unpredictable.

Autopilot full self driving is making dangerous mistakes and being disabled when you still have your hands on wheel and or looking at road it’s a safety system I paid for and it’s illegal for Tesla to disable it and not fix it.

Unintended acceleration while driving at a slower speed. The car suddenly sped up which was very alarming. I had to hit the brake to cause it to slow down. It happened once during a 4 mile trip. My spouse had reported a similar experience earlier in the evening. Also many functions like park assist, traction control etc seemed to be automatically disengaging.

Full self driving suddenly speeds up while waiting at red lights.
