Tesla is expanding the rollout of its Child Left Alone Detection feature, with some Model Y owners in the UK now seeing the safety tool enabled through software update 2025.32.6 (via Not a Tesla App).
Originally introduced in update 2025.14.12 back in May, Child Left Alone Detection uses Tesla’s Cabin Radar technology to spot subtle movements such as breathing — even through blankets or car seats. If the system detects an unattended child, the vehicle will flash its exterior lights, play an alert tone, and send a notification to the Tesla mobile app. These warnings repeat at regular intervals until someone returns to the car. Importantly, cabin data is processed locally and never transmitted to Tesla.
According to Not a Tesla App, the feature is now rolling out to “legacy” Model Ys. It has already been confirmed to be live on some UK vehicles. The feature comes enabled by default, though owners can disable it by navigating to Controls > Safety > Child Left Alone Detection in the car’s settings.
The in-cabin radar technology that powers Child Left Alone Detection is available in the following Tesla vehicles:
This expansion follows a recent run of updates in Tesla’s 2025.32 software branch. Last week’s 2025.32.3.1 release fixed a long-standing Bluetooth audio lag issue on AMD-based infotainment units and resolved a compatibility problem between Start FSD from Park and the “PIN to Drive” security setting.
With the Child Left Alone Detection feature now reaching more vehicles, Tesla is doubling down on its efforts to reduce child heatstroke fatalities in parked cars — a tragedy that still claims dozens of young lives in North America every year.
