Tesla Model Y: Limitations and Inaccuracies

Collision Avoidance features cannot always detect all objects, vehicles, bikes, or pedestrians, and you may experience unnecessary, inaccurate, invalid, or missed warnings for many reasons, particularly if:

  • The road has sharp curves.
  • Visibility is poor (due to heavy rain, snow, fog, etc.).
  • Bright light (such as from oncoming headlights or direct sunlight) is interfering with the view of the camera(s).
  • A camera or sensor is obstructed (dirty, covered, fogged over, covered by a sticker, etc.).
  • One or more of the ultrasonic sensors is damaged, dirty, or obstructed (such as by mud, ice, or snow, or by a vehicle bra, excessive paint, or adhesive products such as wraps, stickers, rubber coating, etc.).
  • Weather conditions (heavy rain, snow, fog, or extremely hot or cold temperatures) are interfering with sensor operation.
  • The sensors are affected by other electrical equipment or devices that generate ultrasonic waves.

WARNING: The limitations previously described do not represent an exhaustive list of situations that may interfere with proper operation of Collision Avoidance Assist features. These features may fail to provide their intended function for many other reasons. It is the driver's responsibility to avoid collisions by staying alert, paying attention, and taking corrective action as early as possible.

CAUTION: If a fault occurs with a Collision Avoidance Assist feature, Model Y displays an alert. Contact Tesla Service.
