Tesla Halloween Mode explained: Trick or Treat, the ghost car and the Fright Show, and why some Teslas miss out

Tesla has turned its cars into Halloween decorations. Software update 2026.38.3, which started reaching owners in early October, added a Halloween Mode to the Toybox, Tesla's menu for fun features. With Halloween on Saturday, October 31, here is what it does and what to watch out for.

How to turn it on

Open Toybox on the center screen and choose Halloween Mode. There are two separate switches: Ghost Costume and Trick or Treat. You can use one or both. The mode stays in the Toybox, so it is not limited to October 31.

Ghost Costume: a haunted screen

• Your car as a ghost: the car on screen gets a glowing white sheet with holes for the lights. The sheet ripples more as you drive faster.
• Parked scene: in Park, the screen shows a graveyard with a haunted house, a full moon, dead trees and pumpkins. You can tap objects, and the Cybertruck has its own scene.
• Driving view: other cars glow green, pedestrians become skeletons, traffic lights turn into stacked pumpkins and the FSD or Autopilot path turns purple.

Trick or Treat: the car scares visitors

With Trick or Treat on, a parked Tesla plays spooky sounds through its exterior speaker and flickers its lights whenever someone walks up. It switches off when you shift out of Park or the car enters Low Power Mode, and it uses extra energy while active.

The catch: Trick or Treat cannot run together with Sentry Mode. Jalopnik also notes that the alarm and walk-away lock are disabled while it is on. If you leave the car on the street on Halloween night, that is worth thinking about.

Sounds, wraps and a light show

• Owl turn signals: an owl hoot plays over the normal indicator click.
• Scary Boombox voice: when you speak through the exterior speaker, your voice comes out spooky instead of robotic. Tesla app version 4.61.6, released October 8, lets you do this from your phone too.
• Lock sound: a Halloween lock sound is available in the Boombox menu.
• Four wraps: including a pumpkin-orange finish and a black design with ghosts and bats, visible on the on-screen car.
• Fright Show: a light show you can schedule. The car flashes its lights, cycles the cabin lighting and opens and closes the trunk to music. Several Teslas together give the best effect.
• Photobooth: photos come out as Polaroid-style prints with Halloween captions and stickers.

The same app update adds a Spooky tab to the Dashcam Viewer, so clips recorded during Trick or Treat are labeled and easy to separate from real Sentry recordings.

Which Teslas get it

Halloween Mode is listed for the Model S, Model 3, Model X, Model Y and Cybertruck, but only for cars with Tesla's AMD Ryzen infotainment computer. Cars with the older Intel Atom computer received the same software version without Halloween Mode. Tesla switched from Intel to AMD in 2021 and 2022, depending on the model.

Tesla has not explained why. Not a Tesla App suspects the graphics are too heavy for the older chip, but notes that simpler extras such as the wraps, sounds and Fright Show should be possible on Intel cars. In a reader poll on that site, 86% of 80 voters said they were greatly disappointed.

Why Tesla does this

Features like this cost Tesla little and keep owners talking about their cars, much like the yearly Holiday Update does. They also show how much of a modern car's character now comes from software. Expect the next round of seasonal extras with the Holiday Update in December.
