Google has begun rolling out Android Auto 16.0, but for a slice of users the update period is being overshadowed by a separate — and stubborn — messaging problem that prevents in-car replies.
The new 16.0 build doesn't appear to deliver any visible changes for most drivers. Instead, it's the timing that's notable: this minor update is arriving while reports continue to pour in from people who use Google Workspace accounts as their primary sign-in for Android Auto and who suddenly cannot reply to messages from their car displays.
What the update does (and doesn't)
If you were expecting dramatic UI tweaks or a shiny new light mode, you'll be disappointed. Android Auto 15.9 is still the widely available release, and 16.0 so far looks like a quiet rollout — no major user-facing features have been identified and teardowns haven't uncovered anything obvious beneath the hood. That doesn't mean 16.0 won't be useful; routine releases often carry server-side toggles or bug fixes that aren't immediately obvious.
The messaging bug: who sees it and what it says
The problem surfaced in late December and has persisted into January. Drivers trying to tap Reply on a message notification sometimes see an error telling them they must "ask your Google Workspace administrator for permission" to reply. That phrasing is important: the behavior appears limited to people signed into Android Auto with Google Workspace (G Suite) accounts rather than @gmail.com consumer accounts.
Multiple outlets and users who reported the issue suggest the cause is server-side rather than an app-level regression — essentially, Android Auto is being told by a backend check that the signed-in Workspace account lacks permission to perform the action. Google has acknowledged the reports but hasn't published a timeline for a fix.
Why this matters: hands-free replies are one of Android Auto's core safety features. When they break, drivers either have to fumble with their phones or ignore messages entirely — neither option is ideal. The problem is niche (Workspace logins are less common for driving devices than consumer accounts), but for affected users it removes a convenience that also reduces distraction.
What you can try right now
- If you use a Workspace account as your primary sign-in, try switching to a secondary consumer (@gmail.com) account in Android Auto to confirm whether the issue disappears. For many, that temporarily restores replies.
- Check with your organization's Workspace admin to see if any new messaging or security restrictions were applied recently. Even though the bug looks server-side on Google's side, it's sensible to verify policy changes from the admin console.
- Keep Android Auto updated via the Play Store and watch official Google channels for an acknowledgement and patch notes.
This glitch also highlights how tightly Google is integrating productivity tools with consumer features. As the company pursues deeper AI hooks into its apps — for example, the growing reach of Gemini into Gmail and Drive — the line between corporate policies and everyday features can blur in unexpected ways.

Likewise, ambitions to bring conversational assistants to navigation hint at how Android Auto could evolve beyond simple messaging here.
For now, Android Auto 16.0 is rolling out quietly and may not change much on your dash. But if you're on a Workspace account and find the Reply button returning that admin-permission message, you're not alone — Google knows about it, and a fix should follow once the company pins down whether the issue lives in its backend logic or in how Workspace account permissions are being interpreted by car interfaces.
