2020 Forester Sport Infotainment Screen Freezing and Blacking Out

Vehicle: 2020 Subaru Forester Sport

My 2020 Subaru Forester Sport has been having major issues with the infotainment system lately. The screen frequently freezes, becomes unresponsive to touch, and sometimes just goes completely black for several minutes before restarting itself. It's really annoying, especially when I'm trying to use navigation or Apple CarPlay.

I've tried doing a soft reset by holding down the power button, but the problem keeps coming back. Is this a known issue with these models? Could it be a software glitch, or is the hardware itself failing? Any advice on what I can do before taking it to the dealership?

ClearTheCode admin answer:

Infotainment system issues like freezing, unresponsiveness, and black screens are not uncommon across various vehicle manufacturers, including the 2020 Subaru Forester Sport. These problems can stem from several sources:

  1. Software Glitches:

    • Outdated Firmware: Ensure your infotainment system's software is up to date. Subaru often releases updates that address bugs and improve stability. You can usually check for updates via the system settings or by visiting a Subaru dealership.
    • Corrupted Data: Sometimes, a corrupted file or setting can cause instability. A factory reset (if available in your system settings) might help, but be aware this will erase personal settings and paired devices.

  2. Hardware Issues:

    • Loose Connections: The head unit itself might have loose wiring connections behind the dash. This is less common for intermittent issues but possible.
    • Overheating: Prolonged use or high ambient temperatures can sometimes cause electronic components to overheat and malfunction temporarily.
    • Failing Components: Internal components within the head unit (e.g., processor, memory) could be failing. This often manifests as increasingly frequent or severe issues.

  3. External Device Interference:

    • USB Devices: Try disconnecting any USB devices (phones, flash drives) to see if they are causing interference or drawing too much power.
    • Apple CarPlay/Android Auto: If the issue primarily occurs when using these features, try testing the system without them to isolate the problem.

What You Can Do:

  • Hard Reset: Disconnect the negative battery terminal for 10-15 minutes. This can sometimes clear persistent electronic glitches by fully cycling power to all modules. Reconnect and test.
  • Check for TSBs: Research if Subaru has issued any Technical Service Bulletins (TSBs) for infotainment issues on your specific model year. These often outline known problems and their solutions.

When to See a Shop: If software updates, resets, and external device checks don't resolve the problem, it's time to visit a Subaru dealership. They have specialized diagnostic tools to communicate directly with the infotainment module, check for internal fault codes (which may not trigger a Check Engine Light), and determine if the head unit needs replacement. A failing head unit is typically covered under warranty if your vehicle is still within the warranty period.
