GM Investigating Google Assistant Voice Command Issue Across Some Newer Vehicles
General Motors has issued preliminary service information for a Google Assistant voice command issue affecting certain Buick, Cadillac, Chevrolet, and GMC vehicles. This is not a recall, and based on the bulletin, engineering is still investigating the cause.
The issue involves Google Assistant voice commands not opening vehicle applications. For example, an owner may say something like, “Hey Google, open the camera app,” and the system may respond that it does not understand the command.
What GM Says Is Happening
According to GM Preliminary Information bulletin PIT6519, some customers may report that Google Assistant voice commands will not open any applications. The bulletin lists the cause as still under engineering investigation.
In other words, GM appears to be aware of the issue, but there is not yet a final repair procedure or confirmed root cause.
Vehicles Potentially Covered By The Bulletin
The bulletin applies to North America and includes vehicles equipped with certain infotainment-related RPO codes, specifically IVD, IVE, and IOK.
| Brand | Model Years Listed | Models |
|---|---|---|
| Buick | 2025 to 2026 | All passenger cars and light duty trucks |
| Cadillac | 2023 to 2026 | All passenger cars and light duty trucks |
| Chevrolet | 2022 to 2027 | All passenger cars and light duty trucks |
| GMC | 2022 to 2026 | All passenger cars and light duty trucks |
What Owners May Notice
The main symptom is fairly specific. Google Assistant may still respond, but it may not properly launch apps through voice command.
For owners of newer GM vehicles with Google built-in, this could be frustrating because voice control is supposed to reduce distraction and make certain functions easier to access while driving.
GM’s Current Guidance To Dealers
The important part of this bulletin is that GM is telling dealers not to replace any parts for this condition at this time.
That usually means GM does not believe this is a confirmed hardware failure, or at least has not yet determined that replacing a component is the right repair. The bulletin says engineering is currently investigating and that the preliminary information will either be updated or replaced with a full technical service bulletin once GM reaches a determination.
Can You Keep Driving The Vehicle?
Yes. The bulletin specifically says customers may continue driving the vehicle while GM investigates the issue.
This appears to be a software, infotainment, or voice-command functionality concern, not a drivability or safety-related warning based on the information currently available.
What Should Owners Do?
If you are experiencing this issue, the best move is to document it and mention it to your GM dealer, especially if your vehicle is still under bumper-to-bumper warranty coverage.
- Write down the exact command you used.
- Note the response from Google Assistant.
- Record whether the issue happens every time or only occasionally.
- Check whether the problem affects one app or multiple apps.
- Ask your dealer to check whether this bulletin applies to your vehicle.
Since GM is still investigating, this may eventually be handled through a software update or a future service bulletin.
Why This Matters
GM has been moving deeper into Google built-in infotainment systems across its newer vehicle lineup, especially in EVs and newer connected vehicles. Voice control, navigation, app access, and vehicle software are becoming a larger part of the ownership experience.
That makes small software issues more noticeable to owners. Even when the vehicle itself drives normally, problems with the infotainment system can make the experience feel less polished.
EV Outdoors Take
Right now, there does not appear to be any action owners need to take. GM is aware of the issue, and engineers are actively working to identify the cause and develop a solution.
Since this appears to involve Google Assistant and app-launching behavior inside the infotainment system, this will likely be addressed through a future software update rather than a hardware repair. For now, stay tuned, and if you are experiencing the issue, it is still worth mentioning it to your GM dealer so it can be documented.
