Fastback Architecture and the Wrap-Around C-Pillar Moulding
The aggressive fastback profile on this sedan creates the visual illusion of a rear sportback liftgate, but the rear window is completely stationary and bonded over a conventional trunk opening. Encircling the entire perimeter of that glass is a signature exterior decorative trim that sweeps from the roofline, down both C-pillars, and spans across the bottom edge of the glass just above the trunk lid. Handling this exterior surround demands particular caution because Kia issued Safety Recall SC346 (NHTSA 25V-510) for model years 2023 through 2025 specifically addressing delaminating adhesive on these exact C-pillar garnishes. If the trim pieces are pried incorrectly during back glass servicing, the underlying lamination separates permanently from the mouldings, preventing them from re-adhering cleanly without flying off at speed.
Whenever a shattered rear window leaves a car exposed to the weather, I typically reach your location within an hour of your call to clean out the cabin and fit a replacement pane before moisture enters the exposed electrical harnesses beneath the rear deck. The glass sits tightly recessed against either a painted steel roof panel or the trailing transition trim of the optional panoramic glass roof assembly, meaning panel gaps must be matched precisely around the perimeter garnish to prevent high-speed buffeting.
Antenna Configurations and Printed Grid Hardware
Every replacement rear window for this model utilizes green solar-tinted tempered safety glass complete with a factory-printed defroster heating grid. What differentiates specific glass variants is the embedded audio and navigation antenna layout printed directly onto the glass surface alongside the horizontal heating traces. Depending on whether your trim level (such as the LXS, GT-Line, EX, or GT) relies on a standalone glass antenna layout or a dual-diversity receiver network, the connector lead count changes.
| Dealer Assembly Part | Glass Hardware Characteristics | Roofline Interface |
|---|---|---|
| 87110-L3000 / 87110-L3001 | Standard defroster grid, single on-glass printed antenna circuit | Standard painted steel roof transition |
| 87110-L3100 / 87110-L3101 | Defroster grid, dual antenna trace layout for audio/navigation | Matches steel or panoramic glass roofline |
Because the AM/FM radio frequency grids are exposed ceramic-printed conductive lines on the inside surface of the tempered glass, they share space with the timer-managed defogger elements. Unlike vehicles that employ rear wiper hardware or externally mounted sensor brackets, this pane remains entirely slick on its exterior face, lacking through-glass holes or integrated camera brackets.
Interior Access at the Package Tray and Pillar Trims
Replacing this rear window requires unlatching the interior trim pillars and freeing the rear parcel shelf. The defroster spade terminals and antenna lead junctions are tucked deep behind the interior C-pillar plastic trim panels. Forcing the wiring out from underneath the plastic without unseating the sail panels bends the factory terminal clips, which ruins the continuity to the defroster relay.
The interior packaging also integrates the center high-mount stop lamp (CHMSL) down on the rear parcel shelf, aimed directly through the lower rake of the back glass. The shelf must be pulled back to clear the light housing from the lower ceramic frit line, ensuring the high-mount brake light beam projects cleanly through the clear patch of the solar glass without rattling against the lower inner edge.
