Tesla Update 2026.32 Adds Automatic Seat Heater Timeout

Tesla’s 2026.32 software introduces an automatic timeout for individual seat heaters to help preserve components and limit energy use during extended trips.

The behavior is documented in Tesla’s updated Model Y owner’s manual and coincides with the rollout of software update 2026.32. Build 2026.32.3 began reaching customer vehicles last week, adding the change despite it not being called out in release notes.

In the manual’s Front and Rear Seats section, Tesla notes:

“To protect vehicle components, an individual seat heater may automatically turn off after approximately 30 minutes of continuous use. This is normal behavior and does not indicate a problem with your vehicle. If a seat heater turns off unexpectedly, you can turn it back on by adjusting the seat heater setting on the touchscreen.”

If a seat cools during a longer drive, you can tap the seat-heating icon on the touchscreen’s bottom climate bar to reactivate it. You can also enable seat heating from the Tesla app.

Protecting Heating Elements and Battery Reserves

The automatic shutoff aims to reduce wear on the resistive heating pads beneath the seats. Seat heaters draw continuous 12-volt power and produce focused heat, which can degrade heating wire insulation or dry seat materials if left on for multi-hour trips.

The addition aligns seat heaters with other timed thermal and electrical loads in the vehicle. Rear window defrosters—which also activate heated side mirrors—turn off automatically after 15 minutes. Wiper blade defrost heaters shut down after 30 minutes, and interior dome lights switch off after about 60 minutes if left on. A roughly 30-minute timer for seat heaters brings them in line with these protections.

Quiet Polishing Ahead of the Holidays

The timeout is part of a series of smaller refinements rolling out with the 2026.32 branch. This update also introduces a redesigned wheel and tire configuration menu and adds Apple Music library search. In addition, update 2026.32 includes a built-in ad blocker for the native web browser.

Late-summer and fall software updates from Tesla typically emphasize minor features and bug fixes, with larger additions often reserved for the annual holiday update later in the year.
