Identifying Your Rio Sedan or Rio5 Hatchback Rear Glass
Working out which back glass your car requires comes down entirely to whether you drive the traditional trunk-lid notchback or the five-door Rio5. Because the rear profiles share no common dimensions or hardware mountings, the glass cannot be interchanged between styles. If you have the four-door sedan, your back window is a solid, direct-glazed unit that remains fixed in place above the rear decklid. If you drive the Rio5, your rear glass sits directly inside the swinging tailgate frame and features a factory pre-drilled pass-through hole near the bottom edge designed specifically to accommodate the rear wiper motor shaft and its protective rubber grommet.
The defroster layouts also distinguish how each glass integrates into the car. While both body variants were built with factory-tempered solar green glass and embedded horizontal electric defroster grids, the power connections interface with completely different interior trim panels. On the sedan, the defroster busbars connect under the lower parcel shelf trim panels and run alongside the interior C-pillar garnishes. In the Rio5, the wiring harness and connectors sit behind the interior plastic liftgate trim panels, feeding directly through the hatch wiring boots alongside the washer fluid tubing for the rear wiper assembly.
Factory Differences: JB Platform Glass Variants and Part Numbers
Under the second-generation JB designation, Kia assigned specific dealer part references that reflect these structural differences. The four-door sedan uses dealer part number 87110-1G010, which superseded the initial 87110-1G000 release. This sedan glass is completely smooth across its exterior surface because it lacks any wiper assembly and leaves the roof-mounted mast to handle AM and FM reception, meaning there are no embedded radio antenna lines or camera brackets bonded to the inner face.
The Rio5 hatchback rear glass corresponds to dealer references 87110-1G200 and 87110-1G220. Because the liftgate structure flexes differently than a welded sedan roof, the glass edge uses a perimeter reveal molding together with specialized factory alignment blocks, referenced under spacer part 86122-2D000, to ensure correct standoff height from the metal flange. I back every aftermarket replacement with a lifetime guarantee on my workmanship alongside a one-year warranty covering the replacement glass itself. This guarantees that your tailgate stays completely watertight around the reveal molding and that the rear heating grid operates without line breaks.
Third Brake Light and Trim Variations
You can also confirm your exact rear setup by checking the position of your centre high-mount stop lamp relative to the glass. On the Rio sedan, the third brake light assembly is mounted flat on the interior package tray, sitting just behind the lower interior glass edge and illuminating outward through an un-fritted clear viewing section of the back window. The ceramic black frit band surrounds the outer border of the glass to shield the underlying polyurethane from sun exposure, but it leaves an open window at the bottom center specifically for that parcel shelf lamp.
The Rio5 handles this lighting completely differently by housing the brake lamp above the glass inside the exterior liftgate header spoiler, eliminating any interior lamp clearance cuts on the back window. Checking whether your brake light shines through the lower window surface or shines from the sheet metal above the frame is the fastest visual confirmation before ordering your replacement glass.
