Description
About the Genesis G90 Tailgate Window Regulator
CRITICAL DOUBLE MISMATCH: (1) Genesis G90 is a full-size luxury flagship SEDAN with TRUNK lid, NOT tailgate. (2) Sedan rear glass (back windshield) is FIXED body glass with NO regulator. Window regulators are for DOOR windows that move up and down.
Customer most likely needs DOOR window regulator. G90 has 4 door windows with 4 regulators: Driver Front, Passenger Front, Driver Rear, Passenger Rear. Specify which door.
G90 is full-size luxury flagship sedan, BMW 7-Series competitor. Successor to Hyundai Equus 2011-2016. Three generations: 1st 2017-2019 (EQ900/G90), 2020-2022 refresh, 3rd gen 2023+ all-new with ‘two-line’ lighting theme. Genesis brand = Hyundai luxury separate brand 2017+.

- Issue 2: Sedan rear glass is FIXED, has no regulator
- Regulators are for door windows: Up-and-down movement
- G90 has 4 door windows: 4 regulators (specify which)

Calogero Frangipane-Volpacchio –
Came searching for ‘tailgate window regulator’ for my 2018 Genesis G90 5.0 Ultimate after my driver front window stopped going up.
