Model Y Collision avoidance malfunctions

 Based on the latest 2025–2026 data, including the recent Hardware 4 (AI4) failures and phantom braking investigations, here are 5 labels for Model Y Collision Avoidance Malfunctions:

Phantom Braking (Tesla Vision),

  • Cause: Relying purely on cameras (no radar), the system can be "tricked" by shadows, bridge reflections, or bright glare, causing the car to brake abruptly at highway speeds.

  • Solution: Tesla releases continuous Over-the-Air (OTA) neural network updates to improve object "depth" perception. Owners are advised to hover their foot over the accelerator in high-glare areas to override sudden deceleration.

AI4 Computer Short-Circuit,

  • Cause: A 2024–2025 hardware defect where the "AI4" (Hardware 4) computer can short-circuit during camera calibration, causing a total loss of safety systems, GPS, and rearview cameras.

  • Solution: Tesla replaces the entire onboard computer for affected vehicles. If the failure occurs within the first few hundred miles, it is typically covered under a high-priority service replacement.

AEB Unavailable / Sensor Blocked,

  • Cause: Automatic Emergency Braking (AEB) often disables due to "vision" obstructions like heavy rain, condensation inside the camera housing, or a failing wheel speed sensor.

  • Solution: Clean the top-center windshield area. If the error persists across drives, a service technician must recalibrate the cameras or replace the specific faulty wheel speed sensor.

Inoperable Reverse Lamps (Recall),

  • Cause: A 2026 Model Y recall was issued because faulty wiring harnesses or housing defects can cause one or both reverse lamps to fail, increasing collision risk during backing.

  • Solution: Tesla inspects and replaces the reverse fascia harness or the lamp housing at no cost to the owner.

Forward Collision Warning Latency,

  • Cause: Software lag in the "Highland" and "Juniper" interface can sometimes delay the visual/audible alert during high-speed approaches.

  • Solution: Adjust the warning sensitivity to "Early" in the Autopilot settings menu. This forces the system to trigger the alert at a further distance to compensate for processing time.

Would you like me to check the specific production dates for the 2026 Model Y reverse lamp recall?
