On the 2017-2024 Subaru Impreza, the 2017+ Impreza (5th generation) uses a thinner, more aerodynamic windshield design that is highly prone to stress cracking, particularly around the EyeSight camera housing area. Cracks often appear spontaneously without any impact, starting from the edges or around the camera mounting bracket. Temperature changes exacerbate the issue. EyeSight-equipped vehicles require dealer recalibration ($200-400) after windshield replacement, adding significant cost.

This issue also affects: Subaru Crosstrek, Subaru Outback

Common Symptoms

  • Crack appearing from windshield edge with no visible impact point
  • Crack originating near EyeSight camera housing
  • Crack spreading rapidly across windshield
  • EyeSight system disabled warning after crack develops

How to Fix

Replace windshield with OEM Subaru glass or equivalent that meets EyeSight specifications. After installation, EyeSight camera recalibration is mandatory at a Subaru dealer (requires specialized targets and procedure). Some aftermarket glass does not meet the optical clarity requirements for EyeSight and can cause system malfunctions. Check comprehensive insurance — many policies cover glass with no deductible.

Typical repair cost:$500 - $1,200
