Tesla update 2026.32's hidden changes: a browser ad blocker, a 20-minute seat heater timeout and a Powershare check

Software ·

Tesla's release notes never tell the whole story. Update 2026.32 quietly adds an ad blocker to the car's browser, switches seat heaters off after 20 minutes and lets you see whether your Model 3 or Model Y supports Powershare.

Every Tesla software update comes with release notes, but they rarely list everything. Update 2026.32 is a good example. Beyond the features Tesla announced, owners and the tracking site Not a Tesla App have found several changes that Tesla did not mention. Some are small conveniences, one might surprise you on a cold morning.

An ad blocker in the car's browser

The built-in web browser now has an ad blocker. It cuts out adverts on web pages, which should make browsing faster and use less data. The difference is likely biggest on older cars with the Intel Atom infotainment computer, where heavy web pages can feel sluggish. The blocker can be switched on or off with an icon at the top of the browser.

Seat heaters now switch off after 20 minutes

This is the change most owners will notice. Seat heaters may now turn themselves off automatically after 20 minutes. Tesla's apparent aims are to protect the heating elements and to catch seat heaters that were left on by accident, for example on an empty passenger seat. If you want more warmth, you simply turn the heater back on.

The timeout applies to the Model S, Model 3, Model X, Model Y and Cybertruck, worldwide. With winter coming in Europe and North America, expect some owners to wonder why their seat went cold halfway through a long drive.

Check whether your car supports Powershare

Tesla recently brought Powershare home backup to the new Model 3 and Model Y, letting the car power a house during an outage, as the Cybertruck already could. Tesla only guarantees support on cars built in October 2026 or later, but some owners of cars built in recent months have found theirs work too.

Update 2026.32 adds a way to check. Go to Controls, Software, then Additional Vehicle Information, and look for the line "Powershare support" near the bottom.

The other changes

  • Grok in six more countries: Israel, the United Arab Emirates, Saudi Arabia, Qatar, Morocco and Jordan. Features include general questions, navigation, music, location-based reminders, vehicle commands and the "Hey Grok" wake word, though they can vary by country. Grok only works on cars with the AMD infotainment computer.
  • Cybercab in Supercharger site maps: a charging Cybercab now shows up as itself in the live site maps, in gold, instead of as a Model 3.
  • New Service Mode tools: a diagnostic panel for the centre and rear displays on the Model 3 and Model Y, an audio network panel for the Cybertruck, preset signal views for technicians, and a guided headlight aiming panel for the Model 3 and Model Y in the US and Canada.

Among the documented features, Tesla limited Apple Music search to your own library and playlists, and added an option to show the car on screen without aero wheel covers.

Why it matters

Undocumented changes are part of how Tesla works: small tweaks ride along with bigger updates, and owners discover them on the road. Most are harmless, but a seat heater that switches itself off is the kind of change people prefer to know about in advance. The Powershare check, on the other hand, answers a real question for owners deciding whether to buy a backup gateway.

What to watch next

Update 2026.38 is already reaching a large part of the fleet and brings Tesla's first Halloween Mode and the Emergency Drive Away feature for Superchargers. Watch whether the seat heater timeout stays as it is, or whether Tesla adds a setting after owner feedback in the cold months.
