📌 UPDATE — April 20, 2026
Tesla's Spring Update (2026.14.1) has expanded to a new wave, now prioritizing Hardware 3 (HW3) and earlier vehicles in the US and other markets. Additionally, AI4 vehicles in countries without FSD access are also receiving the update in this wave, signaling a broader global distribution push. Both Teslascope and Whole Mars Catalog confirmed the expanded rollout on April 20. If you're on HW3 in the US, now is a good time to check your Tesla app for a pending update.
📌 UPDATE — April 19, 2026
Tesla's 2026.14.1 rollout has now reached its 5th batch, hitting approximately 5% of the fleet. Crucially, this wave officially confirms the inclusion of "Hey Grok" — xAI's Grok assistant integrated directly into Tesla vehicles via voice command. The update also bundles the new Self-Driving App [AI4], which lets drivers subscribe with a single tap, learn activation steps, and track ongoing FSD stats in one place.

📌 UPDATE — April 19, 2026 🔍
An undocumented UI change has been spotted in Tesla's 2026 Spring Update (v2026.14.1): a source icon has been added directly adjacent to the volume slider. This minor but notable visual tweak was not mentioned anywhere in Tesla's official release notes, making it one of the hidden changes in this rollout wave. If you've already received the update, check your audio controls — you should see the new icon appearing next to the volume slider in the media UI.

FSD Beta 14.3.1: What's Happening With the Rollout
Alongside the 2026.14.1 UI update, FSD Beta 14.3.1 (firmware version 2026.2.9) is also in active rollout — but it's moving at a different pace than the main software wave. Right now, 14.3.1 is confirmed on Cybertruck, while some Model 3 owners are still sitting on FSD 14.3.
One notable nuance flagged by @wholemars: the Cybertruck does not have an Adaptive Suspension System (ASS), which means certain 14.3.1 behaviors may differ once it lands on Model 3 — a vehicle that does support adaptive suspension. This is worth watching for Model 3 owners who use FSD regularly, as suspension-aware driving adjustments could be part of what 14.3.1 brings to that platform. For more on the FSD side of this update, see our FSD coverage.
🚦 Owner's Action Plan
Verdict: RECOMMENDED — Several features here are genuinely useful and require manual activation.
Step 1 — Check for the update now.
Go to Controls > Software on your touchscreen. If 2026.14.1 is available, schedule it. Wave 2 is live, so expect delivery within the next 24–48 hours if you haven't seen it yet.
Step 2 — Enable Automatic Software Updates.
Once updated, go to Controls > Software > Automatically Install Updates and turn it on. This is a new toggle in 2026.14.1 — your car will now update overnight without you having to think about it.
Step 3 — Set up "Hey Grok."
Go to Grok > Settings and enable the wake word. Try setting a location-based reminder immediately — it's the standout new feature of this update. Say "goodbye" to dismiss Grok when done.
Step 4 — Enable Blind Spot Warning Accent Lights.
This is on by default, but confirm it's active at Controls > Lights > Blind Spot Warning Accent Lights. It's a genuine safety upgrade — interior lights flash red when your blind spot is occupied and you signal.
Step 5 — Check your Dashcam settings.
Go to App Launcher > Dashcam Viewer. Your Recent footage window has expanded to 24 hours. If you want clips on your phone, enable Controls > Safety > View Camera via Mobile App. You'll need the Tesla app at version 4.55.6 or later and Premium Connectivity.
Step 6 — Activate the Supercharger Pricing Filter.
Go to Controls > Navigation > Trip Planner settings and enable the pricing filter. If you have Free Supercharging credits, this prevents the system from routing you to stations where Tesla doesn't control pricing — protecting your credits.
Step 7 — Explore Trips in the Energy App.
Open App Launcher > Energy > Trips. You can now create named trips and track energy across multiple routes. Useful for commuters or anyone doing range testing.
Step 8 — Model 3 owners with FSD: hold tight on 14.3.1.
If you're on FSD 14.3 and haven't received 14.3.1 yet, that appears to be intentional — Tesla is staging the FSD rollout separately from the main UI update. Check all software updates for rollout progress as it develops.
📰 Deep Dive
The Spring Update 2026 is Tesla's clearest signal yet that the xAI partnership is moving from experiment to infrastructure. "Hey Grok" isn't just a novelty — hands-free AI invocation with location awareness puts Grok on par with the best in-car assistants on the market, and the integration is native rather than bolted on. Location-based reminders in particular are the kind of friction-reducing feature that owners will use daily without thinking about it.
The Dashcam expansion from 1-hour to 24-hour retention is quietly one of the most practical changes in this update. For anyone who's ever had an incident and discovered the footage had already been overwritten, this change is long overdue. The addition of speed and steering angle data to downloaded clips also makes the footage significantly more useful for insurance and legal purposes.
On the FSD side, the split rollout between 14.3.1 on Cybertruck and 14.3 still on some Model 3 units is a reminder that Tesla's software distribution is increasingly model-specific. The Adaptive Suspension System variable is a real one — if 14.3.1 includes suspension-aware driving behavior, the Cybertruck deployment is essentially a partial test. Model 3 owners with adaptive suspension may see meaningfully different behavior once 14.3.1 reaches their vehicles. That's worth monitoring closely in the days ahead.
The Autopilot naming change — Navigate on Autopilot becoming Navigate on Autosteer, FSD Computer becoming AI Computer — is cosmetic but legally significant. It aligns Tesla's in-car terminology more precisely with what these systems actually do, which has been a point of regulatory and public scrutiny. Don't expect any behavioral change, but do expect the updated labels to appear across your UI immediately after the update.
