Winter stress cracks and lower frit failures on the RVR
Canadian winter forums for the RVR and Outlander Sport regularly fill up with photos of a crack running straight across the bottom black frit line after a sudden drop in temperature. The acoustic dampening interlayer on the 6102B676 windshield assembly flexes differently from the outer ply when the defroster blasts hot air against frozen glass, causing stone impacts sitting just above the wiper park line to run horizontally within minutes. Because these models on the GS platform position the glass low behind the engine bay hood line, gravel thrown by highway traffic hits hard along that bottom perimeter where stress is highest.
The windshield carries a wide dot-matrix third-visor frit surrounding the mirror base, factory-bonded to take the standard MR306799 rearview mirror wedge mount. If your trim includes the Forward Collision Mitigation and Lane Departure Warning bracket, the replacement glass must house the exact trapezoidal camera window and internal bracket geometry. When I set a replacement, your glass comes covered against material defects for a full year, while the installation workmanship itself is backed for as long as you own the vehicle.
Rain-sensing wiper pads and side pillar retainer clips
The most common post-replacement complaint on Outlander Sport owner threads is erratic automatic wiper behavior. The combination sensor bonded near the rearview mirror handles both dusk-sensing automatic headlamps and infrared rain detection. If the round optical gel pad between the sensor face and the inner glass surface develops even microscopic air bubbles during transfer, the wipers cycle frantically on dry days or fail to trigger in light drizzle. A fresh, bubble-free optical coupler must mate cleanly against the factory-etched glass bracket.
Another area where problems show up is along the exterior A-pillars. Mitsubishi flanks the windshield with rigid side trim mouldings locked into place with single-use plastic snap-fit clips. If someone tries to reuse cracked clips or pulls the moulding upward without releasing the mechanical tabs, the pillar mouldings lift at highway speeds, flutter, or whistle in crosswinds. The upper reveal moulding strip along the roofline must also lay completely flat against the vehicle body to prevent wind buffeting above 80 km/h.
Post-replacement inspection checklist for Outlander Sport and RVR owners
- Inspect both rigid exterior A-pillar trim strips to verify they sit flush against the sheet metal from roofline to fender without loose play or broken retention clips.
- Examine the rain sensor bracket through the outside of the glass above the rearview mirror; look closely for any trapped air pockets, cloudiness, or voids in the round clear gel pad.
- Check the two-piece plastic cowl louver beneath the tandem wiper arms to ensure both halves interlock correctly and seat tightly beneath the bottom glass edge.
- Test your automatic wiper settings with a water spray bottle to confirm the wipers sweep consistently without phantom dry wipes.
- Verify that the camera optical window in the black ceramic frit is crystal clear, centered, and free of smudges or adhesive residue in front of the lens.
