Owner's description
The contact owns a 2026 Tesla Model Y. The contact stated that while driving at various speeds in Autopilot Mode, the vehicle misread nearby road signs. The contact stated that a road sign in Illinois marked 83 and 60 was misread by the software (V12 2025.22.6E575ED98D527), while in Autopilot, with 60 being the Speed Limit, and the vehicle unintendedly accelerated or decelerated to 60 MPH. While driving on a road with a slight ramp with the Speed Limit of 40 MPH or 45 MPH, once the vehicle was on the ramp, the vehicle unintendedly accelerated to approximately 50 - 55 MPH. There were no warning lights illuminated during the failures. The contact stated that the vehicle failed to exceed 40 - 45 MPH while driving on other roadways. The vehicle failed to maintain the desired speed during each failure without a warning light being illuminated. The dealer was contacted, and the vehicle was taken to the dealer, but the vehicle was not yet diagnosed or repaired. The manufacturer was informed of the failure.
