1. What is Tesla’s Cabin Radar?

   Tesla’s Cabin Radar is a cutting-edge 4D imaging sensor in the 2025 Model Y (Juniper) and Cybertruck. Located near the front-row dome lights, it detects human presence, including subtle movements like heartbeats and respiration, even through car seats or blankets.

   This technology aims to prevent tragedies like child heatstroke deaths in vehicles. By 2025, all 2022+ Model Ys will receive Cabin Radar functionality via OTA Update 2025.2.6.

2. How Does Cabin Radar Work?

   The radar uses millimeter-wave signals to create a 3D map of the cabin. Unlike cameras or motion sensors, it:

  • Operates in low-power mode (minimal battery drain).
  • Detects through organic, non-metallic materials (e.g., car seats).
  • Monitors micro-movements (breathing, heartbeat).

   If a child is left behind, the system triggers alerts via the Tesla app and activates safety protocols like climate control or hazard lights.

3. Why Cabin Radar Matters: The Heatstroke Crisis

NHTSA reports 37 child deaths annually from vehicular heatstroke. Key insights:

  • 52% occur when a child is forgotten in a car.
  • 55% of victims are under 2 years old.
  • Heatstroke can happen even in 70°F weather (car interiors reach 115°F+).

Tesla’s Cabin Radar directly addresses these risks with real-time detection.

4. Key Features & Benefits
Feature Benefit
4D Imaging Detects even stationary occupants (e.g., sleeping infants).
Low Power Use Doesn’t drain the EV battery.
OTA Updates Future-proof tech for older Model Ys (2022+).
Multi-Function Use Supports seat occupancy detection, auto parking brake, and driver monitoring.

Bonus: Child Presence Detection will soon roll out to all Tesla vehicles.

5. How Tesla’s Radar Compares to Other Systems

   Most carmakers use weight sensors or door alarms, which fail if a child:

  • Moves out of the sensor zone.
  • Is covered by a blanket.

Tesla’s Cabin Radar outperforms with: 

  • ✅ Non-visual detection (works in darkness or obstructions). 
  • ✅ Medical-grade accuracy (detects breathing/heartbeats). 
  • ✅ No false alarms from inanimate objects (e.g., groceries).

6. FAQs About Cabin Radar

Q: Is Cabin Radar always active? 

A: Yes, but it uses minimal power to avoid battery drain.

Q: Does it work for pets? 

A: Tesla hasn’t confirmed pet detection, but the radar can sense movement from animals.

Q: What about privacy concerns? 

A: The radar doesn’t record video or audio—only detects presence.

Q: Will older Teslas get Cabin Radar? 

A: Yes! 2022+ Model Ys will receive it via OTA updates.

Final Thoughts 

   Tesla’s Cabin Radar is a game-changer for child safety, blending advanced sensor tech with real-world problem-solving. By tackling heatstroke risks head-on, Tesla sets a new standard for automotive safety innovation.
