2020 Encore Infotainment Screen Goes Black Intermittently

Vehicle: 2020 Buick Encore Preferred

Hi all,

I'm having a frustrating issue with my 2020 Buick Encore Preferred. The infotainment screen, which controls everything from radio to navigation, has started going completely black intermittently. Sometimes it comes back on its own after a few minutes, other times it stays off until I restart the car. When it's black, it's also unresponsive to touch.

It seems to happen randomly, not tied to bumps or specific actions. I've tried restarting the car, but that's not a consistent fix. It's really annoying, especially when I'm trying to use the backup camera or navigation. Has anyone else experienced this with their Encore or a similar Buick model?

Are there any known software glitches or common connection issues I should be looking into? I haven't seen any warning lights on the dash when this happens, and no specific OBD codes seem to be triggered.

ClearTheCode admin answer:

Intermittent black screens and unresponsiveness in the infotainment system of your 2020 Buick Encore Preferred can be a common and annoying problem. While there isn't usually a specific OBD code for this, it often points to a few key areas.

Here are the most common causes and troubleshooting steps:

  1. Software Glitch/Freeze:

    • Solution: Try a 'soft reset' of the infotainment system. This usually involves holding down the power button on the radio for 10-15 seconds until the system reboots. Check your owner's manual for the exact procedure for your model. Sometimes, a simple reboot can clear temporary software issues.

  2. Loose Connections:

    • Cause: The wiring harness connecting the screen to the head unit or the main vehicle network can become loose over time, especially with vibrations. This is less common but possible.
    • Solution: This typically requires professional intervention to access and inspect the connections behind the dashboard.

  3. Blown Fuse:

    • Cause: A dedicated fuse for the infotainment system might be blown, leading to power loss. However, since it's intermittent, a loose fuse connection is more likely than a fully blown fuse.
    • Solution: Check your owner's manual for the location of the infotainment/radio fuse in your fuse box (usually under the hood or inside the cabin). Inspect it for damage and ensure it's seated firmly.

  4. Hardware Failure:

    • Cause: The infotainment head unit or the screen itself could be failing. This is a more serious issue.
    • Solution: If other troubleshooting steps fail, this would require replacement of the faulty component.

  5. When to See a Shop:

    • If a soft reset and fuse check don't resolve the issue, or if the problem becomes more frequent and persistent, it's time to visit a Buick dealership or a reputable automotive electronics specialist. They can perform diagnostic tests, check for any underlying communication codes (U-codes) that might not trigger a dash light, and determine if a hardware repair or software update is needed. Since your vehicle is a 2020 model, it might still be under warranty, so check with your dealer.
