Pre-Installation Checks on Telluride Back Glass Part FB28160YP
When unboxing the replacement tailgate glass for your Telluride—cataloged under NAGS part FB28160 or FB28160YP—I verify several structural attributes before taking apart your liftgate. Kia transitioned its factory part number from 87110-S9000 on the 2020–2022 models to 87110-S9200 for the 2023–2025 refresh, but the physical glass perimeter across all trims, from the base LX and S up to the SX Prestige, X-Line, and X-Pro, shares the exact same single-piece stationary footprint.
Because this vehicle uses a roof-mounted shark fin for satellite and radio reception, the back glass contains zero integrated antenna lines. Instead, the inspection focuses strictly on the defroster elements and manufacturing integrity:
- Defroster Solder Tabs: I inspect both electrical terminal contacts on the left and right borders of the glass. These tabs connect directly to the liftgate wiring harness to power the defogger lines, and they must be solidly bonded to prevent open circuits under high electrical load.
- Factory Privacy Tint: Unlike the windshield and front side doors which utilize acoustic laminates, the back window is a solid, single-pane tempered safety glass with dark embedded privacy shading. I inspect the panel against a light board to ensure the dark dye is uniform without cloudy fade zones or pinhole light leaks.
- Lower Setting Spacer Points: I inspect the bottom edge where OEM spacers (part 87112S1000) support the glass to make sure the edge profile will sit evenly between the liftgate shell and the bottom exterior latch molding.
Alignment Around Telluride Spoilers, Appliques, and Trim Mouldings
Replacing the back glass on this SUV requires close attention to the perimeter components that surround the liftgate frame. Once you reach out and book, I can usually be at your vehicle in about an hour to assess the broken panel and manage the trim clearances. The top of the rear window tucks directly beneath the aerodynamic roof spoiler housing the high-mount stop light. If the glass is set even two millimeters too high, the upper edge will rub against the painted spoiler flange, creating vibration stress that can compromise tempered glass over rough pavement.
The sides of the rear window are bordered by vertical gloss or matte black applique garnish moldings. For 2023–2025 Telluride models, Kia issued recalls concerning exterior window and door belt mouldings detaching at highway speeds. During a back glass job, I inspect these lateral appliques and their plastic retainers to confirm they seat flush against the glass borders without loose clip tension.
Post-Installation Clearance and Defroster Circuit Inspection
After the rear window is in position, I run checks on the exterior reveal and internal trim fitment:
- Defroster Grid Continuity: Before snapping the interior upper and side tailgate garnish panels back into place, I plug the harness into the solder tabs and test the heating lines with a multimeter. A proper electrical draw confirms the grid will clear frost evenly without hot spots.
- Interior Garnish Concealment: The snap-in tailgate plastic panels must fully cover the perimeter edge. I check that the side garnish pieces click cleanly into their retainers without pressing directly into the glass surface.
- Tailgate Closure Gaps: I check the exterior gap between the lower edge of the new glass and the rear latch release trim finish molding. The space must remain uniform from corner to corner so water sheds correctly into the liftgate runoff channels.
Why did the original back window shatter without an impact?
The Telluride uses tempered rear safety glass that exists under high internal tensile stress. Spontaneous failure often tracks back to thermal shock, such as activating the rear defroster grid on sub-zero mornings, or microscopic manufacturing impurities in the glass batch that expand and contract unevenly during sudden temperature swings.
Is the rear glass different on the rugged X-Line or X-Pro trims?
No. While the X-Line and X-Pro editions feature distinct suspension heights, roof rails, and exterior bumper trim styling, the liftgate stamping and the rear window itself are identical across all trims. The FB28160YP glass unit fits any 2020–2025 Telluride trim level.
Can the heating grid be repaired if a defroster line fails?
Individual line breaks caused by scratches to the interior ceramic grid can sometimes be bridged with conductive silver paint, but broken solder tabs at the glass boundary harness cannot be reliably resoldered without cracking the tempered glass. If the power terminal separates from the glass edge, replacing the rear window is the only permanent repair.
