Subaru Legacy: EyeSight Stereo Camera Misalignment After Windscreen Replacement

The EyeSight driver-assist system on BS-generation Legacy (2015–2020) uses two stereo cameras mounted at the top of the windscreen. Any windscreen replacement — including insurance-covered glass — requires a Subaru-dealer recalibration of the stereo camera baseline. If the recalibration is not performed or is performed incorrectly by a non-Subaru workshop, the system issues phantom collision warnings, fails to detect vehicles at correct distances, or disables itself entirely. This is a known and documented issue widely reported in markets where windscreen replacements are common (stone chips, etc.).

• EyeSight warning light on dashboard (orange steady or flashing)
• Phantom or false pre-collision warnings with no obstacle present
• Adaptive cruise control disengaging unexpectedly
• Lane departure warnings firing on straight, clearly marked roads
• System fully disabled with 'EyeSight Disabled' message on multi-information display

1. 1

   Check EyeSight indicator light on dashboard — a steady orange or flashing indicator signals a calibration fault.

2. 2

   Test the pre-collision braking and lane-keep functions on a road with clear lane markings.

3. 3

   Ask whether the windscreen has ever been replaced and whether Subaru dealer recalibration was performed and documented.

$350 to $900 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

• “Has the windscreen ever been replaced, and was EyeSight recalibration carried out by a Subaru dealer with documentation?”
• “Is the EyeSight system currently active and functioning — can I see it operational during the test drive?”
• “Has the EyeSight warning light ever appeared on the dashboard?”

The failure described above is documented in published sources — owner forums, technical service bulletins, recall notices and workshop write-ups — held in our fault database. The inspection instructions and the cost estimate are KickTyres’ own interpretation of them, and it is a starting point for an inspection rather than a manufacturer statement.
