Break-Ins and Rear Cargo Vulnerabilities on the Soul
Smash-and-grab thefts frequently target the rear quarter window of this crossover because thieves use the opening to reach down and release the rear seat latch or bypass the cargo cover. When that small rear side glass is shattered, it leaves tempered glass pebbles scattered throughout the cargo area and down inside the rear wheel arch interior trim. For replacement, the driver side rear quarter uses NAGS part number FQ28181YP, corresponding to the original equipment reference 87810-K0120, which superseded the earlier 87810-K0020. The passenger side glass is cataloged as FQ28180YP, matching the factory number 87820-K0120 that replaced 87820-K0020.
Unlike roll-down windows mounted on mechanical regulators, this quarter panel is a fixed glass assembly that forms the visual bridge between the rear door line and the vertical taillights. While factory glass comes through the Kia parts network, I use quality aftermarket replacements manufactured by brands like Pilkington, PGW, FYG, or XYG, which mirror the exact factory privacy tint and match the surrounding tempered side glass. These aftermarket panels include the standard dark perimeter frit band, which serves as a ceramic shield against ultraviolet light degradation for the bonding line underneath.
Encapsulated Trim and Alignment with the Floating Roof Appliqué
The third-generation Soul is recognized for its floating roof design, where the rear pillar features a large gloss-black garnish bearing the embossed Soul model name script. The exterior edge of the quarter glass sits flush against this C-pillar appliqué trim panel, which falls under the 87860-K0000 series part numbers. If an installer attempts to pry near that pillar garnish or fails to account for its interlocking perimeter, the plastic trim can bend, crack, or lose its painted finish, creating wind whistles at highway speeds.
Proper fitment also relies on integrated hardware studs manufactured directly into the encapsulated glass border. These studs pass through dedicated holes in the body's stamped steel pillar, secured from the inside by factory retaining nuts under part number 92415-3M000. These fasteners are not meant to clamp the glass tight against raw sheet metal without adhesive; rather, their mechanical role is strictly to keep the glass assembly perfectly indexed against the rear garnish and roofline while the adhesive sets. Because this glass is entirely passive, it lacks embedded defroster grids, integrated antennas, or wiring harnesses, meaning proper alignment with the exterior garnish is the primary technical detail to get right.
