Tesla Delivers 2025.32.6 Software to 34% of Cars

Tesla started pushing the 2025.32.6 update to cars on September 15, 2025, reaching about 2 percent of its global fleet at first. As of the fourth wave, the update is on 34 percent of Tesla vehicles, with installation seen on over 2,400 cars across 14 countries.

The rollout began with a small group, widened with each batch, and climbed fast after feedback and data collection confirmed stability. Tesla’s staged approach helps catch issues early and keeps cars on the road, not in service.

New Features in This Release

Child Detection Feature Goes Wider

Tesla’s child left alone detection has been updated and is now on more vehicles, including older Model Y versions and cars in Europe. The system uses sensors inside the cabin to spot movement, including small signs like breathing, even under covers.
If the feature finds a child inside with no adults, the car flashes exterior lights, beeps inside, and sends a warning to the Tesla app. Alerts repeat until someone comes back to the car. None of this data leaves the car; it processes everything locally for privacy. This safety tool is active by default but can be switched off in Controls > Safety > Child Left Alone Detection.

Security Patches

Tesla added new security fixes in this update, but details are not public. Engineers continue to make the system harder to hack or abuse.

Bundled Improvements from Earlier Releases

Low Power Mode

This mode saves battery power when cars are parked a long time. It does this by turning off features like Sentry Mode, Summon Standby, Cabin Overheat Protection, and more. Drivers might see up to 20 percent less battery use in a week of parking.

Better Airbag Control

Cars with AMD Ryzen chips received upgrades to their airbag system. By tying together camera input from Tesla Vision and standard sensors, airbags can start inflating a split-second before impact if the system predicts a crash.

“Rave Cave” Light Sync Tweaks

Ambient lights in the car now remember a driver’s last setting and can turn on when shifting into park. To access it, go to App Launcher > Toybox > Light Sync

What Cars Can Use These Features

Child Left Alone Detection:

Model Y (2022+)
Model 3 (2024+)
Cybertruck
Model S and X (2021+)

Improved frontal airbags:

Only cars with AMD Ryzen processors

With rollouts touching vehicles in 14 countries, Tesla is answering safety concerns, especially in Europe where more cars now get child cabin alerts. Each year about 37 children die globally from being left in cars, often from heatstroke.

The 2025.32.6 release is one of Tesla’s largest for safety and security, both in feature set and in how many cars get it fast. Tech like camera-driven airbag deployment and cabin radar put Tesla ahead in predictive safety.

This update will reach more cars as each batch goes out, cementing Tesla’s place as a leader in delivering new safety tech by over-the-air delivery.

Extra Features Added in This Update

You can now set Dog Mode to a minimum cabin temperature of 64°F (18°C).
There are prompts to enable FSD (Supervised) if drowsiness or lane departure is detected (undocumented but observed in updates).
Improved FSD (Full Self Driving) visualizations now show enhanced graphics when changing to reverse on vehicles with Intel hardware (undocumented).
