Tesla's Spring 2026 Update: Hey Grok, a Real FSD App, and 24-Hour Dashcam
5 min read read
Tesla pushed its Spring 2026 software update on April 13, and it's the largest user-facing release since Hardware 4 launched. Five features actually change how owners use the car day-to-day, and they're worth understanding before you accept the install.
Hey Grok — Hands-Free Wake Word
You can now launch xAI's Grok assistant by saying "Hey Grok" — no screen tap, no voice button. Say "goodbye" to dismiss it. Tesla rolled the wake word out to every region that already supported Grok: North America, Australia, New Zealand, and parts of Europe.
Grok also gained location-based reminders. The example Tesla used in its release notes: "remind me to pick up milk when I'm near home." This is the first time the in-car AI has held state across drives in a way that's actually useful.
A Redesigned Self-Driving App
HW4 (AI4) vehicles get a new Full Self-Driving app that finally puts subscription, statistics, and feature controls in one place. Subscribing to FSD (Supervised) is now one tap at $99.99/month — no separate web checkout. The app also includes a dedicated stats dashboard so owners can see disengagement rates and miles driven autonomously without third-party tools.
| Feature | Where It Lives | Tap Count to Reach It |
|---|---|---|
| FSD subscription | FSD App | 1 (was 4–5 via web) |
| FSD stats | FSD App | 2 (was unavailable) |
| FSD profile presets | FSD App | 2 |
| Disengagement log | FSD App | 2 |
Pet Mode Got Three Animal Animations
Pet Mode — the feature that keeps the cabin climate-controlled when you leave a pet inside — now displays one of three animated characters on the touchscreen so passersby know the situation is intentional. The choices: dog, cat, or hedgehog. The hedgehog is real. The Tesla community has already nicknamed it "Cyberhog."
The feature isn't cosmetic. The animation includes a clear "the climate is on, the owner is coming back" message visible from outside the car, which is the actual function — reducing the small but real risk of a window-smashing intervention from a well-meaning bystander.
Automatic Overnight OTA Installs
Tesla cars can now automatically install downloaded software updates overnight while parked. You no longer have to remember to approve each one before bed. This sounds minor; it's not. The owner-cohort that lagged a full release behind because they kept tapping "later" is about to vanish from the install metrics.
Dashcam Now Holds 24 Hours of Footage
The dashcam buffer expanded to a rolling 24 hours of footage — a major upgrade from the previous one-hour limit. Any clip can be permanently saved through the Dashcam Viewer app. For owners who wanted dashcam footage from a hit-and-run noticed the next morning, this is the difference between "got it" and "lost it."
"The Spring 2026 update is one of the most significant releases in recent memory." — Tesla Oracle
The Bottom Line
Hey Grok is the headline feature, but the workflow improvements (FSD App, automatic installs, 24h dashcam) are what owners will actually feel within the first week. If you're still waiting on the install, your queue is normal — Tesla typically ramps to fleet-wide over four to eight weeks.
