EyeSight disabled warning on 2020 Crosstrek - what gives?

Vehicle: 2020 Subaru Crosstrek Limited

Hey everyone,

I've got a 2020 Subaru Crosstrek Limited with about 45,000 miles, and lately, I've been getting an intermittent 'EyeSight Disabled' warning on my dashboard. It usually happens when it's raining heavily, or sometimes when the sun is directly hitting the windshield, but it's also popped up on clear days for no apparent reason.

The warning usually clears itself after a while, but it's concerning, especially since I rely on those safety features. Is this a common glitch with the EyeSight system, or could it be a sign of a more serious problem? I haven't had any windshield replacements.

Any thoughts or similar experiences?

The 'EyeSight Disabled' warning on your 2020 Subaru Crosstrek is a common concern for owners, and while it can sometimes indicate a temporary condition, it's important to understand the potential causes and when to seek professional help.

Subaru's EyeSight system relies on two stereo cameras mounted at the top of your windshield to function. Anything that obstructs their view or affects their calibration can trigger this warning.

Here are the most common reasons for the EyeSight system to disable itself:

  1. Environmental Factors:
    • Cause: Heavy rain, snow, fog, direct sunlight, or even extreme heat/cold can temporarily impair the cameras' ability to 'see' clearly. Dirt, ice, or condensation on the windshield in front of the cameras is also a frequent culprit.
    • Action: Ensure your windshield is clean, especially the area in front of the EyeSight cameras. Use your defroster to clear any condensation.
  2. Windshield Damage or Replacement:
    • Cause: Even a small crack or chip in the windshield within the camera's field of view can cause issues. If the windshield has been replaced, improper installation or failure to recalibrate the EyeSight system afterward will almost certainly lead to malfunctions.
    • Action: Inspect your windshield carefully for any damage. If you've had a replacement, ensure it was done by a Subaru-certified facility that performed the necessary EyeSight recalibration.
  3. Electrical or Sensor Issues:
    • Cause: Less commonly, there could be an underlying electrical issue, a faulty sensor, or a problem with the EyeSight control unit itself.
    • Action: While less likely for intermittent issues, persistent warnings without obvious environmental causes point to this.
  4. Diagnostic Codes:
    • Action: A dealership can connect to your vehicle's diagnostic system and check for specific EyeSight-related trouble codes, such as C1431 (EyeSight Camera Malfunction) or C1432 (EyeSight Control Module Malfunction), which can pinpoint the exact problem.
  5. When to See a Shop:
    • Immediately: If the warning is constant, appears even in ideal driving conditions, or if you notice any other warning lights accompanying it.
    • Soon: If the issue persists after ensuring your windshield is clean and clear, or if you have any doubts about the system's integrity. A Subaru dealership has the specialized equipment to diagnose and recalibrate the EyeSight system properly. Do not attempt to repair or adjust the cameras yourself.
