Subaru Outback: Windscreen cracks spontaneously or from minor stone chips

Windscreen cracks spontaneously or from minor stone chips is a very common body & rust fault on the Subaru Outback on the 2021 onward cars, and we rate it major. Putting it right costs $800 to $2,600 at New Zealand independent workshop rates. Below is what goes wrong, the symptoms to notice on a test drive, where to look, and what to ask the seller before you hand over any money. It is one of 34 documented faults on the Subaru Outback.

All Subaru Outback faults34 documented faults on this model

What you are looking at

No photograph available

We do not hold a verified photograph for this fault yet. We would rather show none than show a picture of something else.

What goes wrong

The 6th-generation (BT) Outback's acoustic-laminated windscreen is widely reported to crack from very minor impacts or seemingly on its own, with cracks spreading rapidly across the full width of the glass. Complaints span the 2020-2022 model years and continue the pattern seen on earlier Subarus, prompting a consolidated class-action lawsuit that Subaru settled for affected Legacy and Outback owners. Because the windscreen carries the forward EyeSight stereo camera, every replacement also requires an EyeSight recalibration, sharply increasing the cost versus an ordinary car. Buyers should treat a cracked or already-replaced windscreen as expected rather than exceptional on this generation.

What you would notice

  • Crack appears after a small stone chip and spreads across the glass within days
  • Crack forms with no recalled impact, often from the bottom edge upward
  • EyeSight/lane-keep warning lights after glass replacement if not recalibrated

How to check it

Where to look. Front windscreen (acoustic laminated glass) and the EyeSight stereo camera behind the rear-view mirror

Inspect the full windscreen in raking light for chips, star breaks and creeping cracks, especially along the lower edge near the heated wiper-park zone; check for a replacement-glass logo or fresh urethane bead indicating a prior swap, and confirm EyeSight has been recalibrated (no ADAS warning lights on the dash).

What it costs to put right

$800 to $2,600 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.

Ask the seller

  • “Has the windscreen been replaced, and if so was EyeSight recalibrated by a Subaru dealer or approved calibrator?”
  • “Are there any current chips or cracks, and is the car within any Subaru windscreen goodwill/warranty extension?”
  • “Do any driver-assist or lane-keep warning lights appear on start-up?”

Now check the Subaru Outback you are actually looking at

Everything above is true of the model, and it is free. What it does not tell you is whether THIS car has been looked after: its odometer history and whether the reading has ever gone backwards, whether there is still money owing on it, whether it has been reported stolen, how many owners it has had and what it is really worth today. That comes from the official records for that plate. Enter the plate for the free details, or get the full history and a market valuation from $13.49.

Subaru Outback buyer questions

Is windscreen cracks spontaneously or from minor stone chips serious on a Subaru Outback?

We rate it major and very common on the Subaru Outback. The 6th-generation (BT) Outback's acoustic-laminated windscreen is widely reported to crack from very minor impacts or seemingly on its own, with cracks spreading rapidly across the full width of the glass. Complaints span the 2020-2022 model years and continue the pattern seen on earlier Subarus, prompting a consolidated class-action lawsuit that Subaru settled for affected Legacy and Outback owners. Because the windscreen carries the forward EyeSight stereo camera, every replacement also requires an EyeSight recalibration, sharply increasing the cost versus an ordinary car. Buyers should treat a cracked or already-replaced windscreen as expected rather than exceptional on this generation.

How much does it cost to fix on a Subaru Outback?

$800 to $2,600 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.

Which Subaru Outback years are affected?

Our research records this fault on the 2021 onward Subaru Outback. Build dates move around, especially on imported cars, so treat the range as the years to look hardest at rather than a guarantee either way. The official records tell you the exact build and first registration date for the car in front of you.

How do I check for it before I buy?

Inspect the full windscreen in raking light for chips, star breaks and creeping cracks, especially along the lower edge near the heated wiper-park zone; check for a replacement-glass logo or fresh urethane bead indicating a prior swap, and confirm EyeSight has been recalibrated (no ADAS warning lights on the dash).
