- Driving visualization: Nearby vehicles appear in spooky colors, and other elements of the visualization receive Halloween-themed treatments. These are display effects, not a change to how the car drives.

- Trick or Treat Mode: When visitors approach, the car plays spooky sounds and flickers its lights.
- More themed options: Owners can schedule a Halloween light show, select themed vehicle wraps and a lock sound, and use a Halloween-themed Photobooth.

Will it stay after Halloween?
The release-note wording—“Spread holiday fear year round”—indicates Halloween Mode is intended to be usable beyond the holiday itself. That is the best available indication that it may remain accessible afterward, not a promise that Tesla will keep every feature unchanged or available indefinitely. 1
Compatibility: what is known and what is not
The available information does not establish that every Halloween feature works on every Tesla. A software tracker lists Model 3 and Model Y vehicles with AI4 among the vehicles associated with the update, but that is not a complete compatibility list. The provided release information also does not confirm the full feature set on older Intel-equipped infotainment systems. 1
9
In short, the update’s availability on a vehicle should not be taken as proof that every Halloween effect is supported on it. Owners should check the release notes shown for their own vehicle; compatibility across other models and Intel systems remains uncertain in the available reporting. 1

Other changes in 2026.38.3
The update also includes Emergency Drive Away, which allows a driver to shift into Drive while a Supercharger cable is still connected. The release notes say to use it only in an emergency: driving away with the cable attached can damage the vehicle and charger, and activating the feature shares short camera recordings with Tesla. 1
Powershare Home Backup lets eligible newer Model 3 and Model Y vehicles paired with a Powerwall 3 supply power to a home during an outage. Tesla Energy says the feature can extend home backup by more than two days. 5

These additions are separate from Halloween Mode. The update is not described as adding a Full Self-Driving feature or changing the car’s driving operation. 11
