2022 Genesis G90 Problems: 12 Known Issues

On the 2017-2022 Genesis G90, first-generation G90s use an electronically controlled air suspension that is a recurring high-cost failure point. Owners report pinhole leaks in the air struts/bags, failed leveling (height) sensors, exploded air dryers and burnt-out compressors, producing a saggy or uneven stance, knocking noises over bumps and a harsh ride. Repeated compressor/strut failures can run into the thousands of dollars. Genesis abandoned this air-suspension design on the redesigned G90.

On the 2022-2023 Genesis G90, per NHTSA Recall 24V282000 / Genesis 022G, low-pressure fuel pump assemblies in ~1,364 G90 sedans (2022-2023 MY, built Jun 2, 2021 - Sep 14, 2022) may contain impellers that deform under high ambient/underhood temperatures, causing mechanical interference with the pump housing and shutdown. Affects both 1st-gen (3.3T Lambda / 5.0L V8) 2022 G90s and 2nd-gen (3.5T Smartstream) 2023 G90s — two distinct pump part numbers in the recall (31110-D2000 Theta-family applicator and 31110-T1050 Lambda-family applicator across the campaign).

On the 2017-2022 Genesis G90 3.3L Twin-Turbo V6 (Lambda II), on G90s equipped with the 3.3L twin-turbo V6, the original left-hand turbocharger oil feed pipe and hose assembly was manufactured from a material that becomes brittle after prolonged heat exposure and repeated heat/cool cycling. The pipe cracks and leaks pressurized engine oil directly onto the hot exhaust manifold, dramatically increasing the risk of an under-hood fire. This drove NHTSA Recall 24V191 (Hyundai/Genesis campaign 019G), which expanded and replaced earlier campaign 19V-538. Owners are warned it can ignite whether parked or driving.

On the 2017-2022 Genesis G90, first-generation (DH) G90 sedans with the large panoramic glass roof commonly develop creaks, rattles and squeaks from the roof/headliner area, plus wind-noise vibration over the glass. Root causes owners and dealers have found include sunroof frame/track attachment bolts that back off or were under-torqued from the factory (one documented case found 32 loose bolts), plus metal-on-metal contact in the frame. Genesis addresses the noise complaints with TSB 23-BD-014G. Note: some owners also report spontaneous panoramic-glass shattering (a known Hyundai/Kia glass-roof failure mode), but that is less well documented specifically on the G90 and coverage is often disputed absent proven breakage.

On the 2017-2022 Genesis G90, the G90's power soft-close doors use a motorized cinching latch that pulls a door held at the first detent fully shut. On first-generation cars this system fails one door at a time: the cinch motor stops running, so the door sits visibly proud and the ajar warning stays lit until the door is slammed manually, or in the worse version the latch actuator sticks and the door will not open at all from inside or out. Owners on the Genesis forums report it appearing intermittently on a front passenger door, being fixed under warranty, then reappearing on a different door - which points to a component-level failure of the latch/actuator assembly rather than a one-off. A dead cinch motor is an annoyance, but a latch that will not release is a genuine egress problem for a rear passenger.

On the 2017-2022 Genesis G90, owners of the power-operated trunk on the first-generation G90 report intermittent failures where the decklid will not fully close and latch when lowered, or will not release and rise when commanded (some report a stick roughly every few openings). The trunk uses a power latch (cinch) module and a power drive (raise/lower) module, either of which can fail or fall out of calibration. Owner and dealer reports indicate lid misalignment is a frequent root cause - striker, rubber stopper and trim adjustment often resolves it - and that simply replacing the latch and drive motor does not always help. Low 12V battery voltage can also cause the symptom. This is a body/closure electromechanical issue distinct from the general parasitic battery-drain complaint.

On the 2017-2022 Genesis G90, distinct from the panoramic sunroof rattle, first-generation G90 owners report a whistle or roar entering the cabin at the front driver's door - typically from the lower or forward edge of the door glass and the A-pillar area - that becomes obvious above roughly 60 mph. It is glaring on this car precisely because the rest of the cabin is so quiet. The causes documented by owners are the frameless-feel door glass sitting slightly proud in its run channel so it does not fully compress the seal at speed, and door weatherstrip and A-pillar molding that seals inconsistently from the factory. In one documented case a Genesis field representative measured the A-pillar as 10-20 decibels louder than the rest of the car and the company replaced every seal on the vehicle plus an exterior mirror.

On the 2017-2022 Genesis G90, coolant weeping/leaks are frequently reported and seen by technicians on first-gen G90s — commonly from the water pump and thermostat housing on the 3.3T, plus O-ring/gasket seepage on the 5.0. Left unaddressed, slow coolant loss risks overheating and cylinder-head damage on the Lambda/Tau V6/V8 family.

On the 2017-2022 Genesis G90, g90 owners report a pronounced pedal and steering-wheel pulsation under braking from highway speed, appearing at mileages where a luxury sedan's rotors should still be flat. Owners on the G90-specific forum document rotors replaced repeatedly - one reports four sets since 2018 on very low mileage - with the symptom returning each time. Two mechanisms are argued in the community and both are real: uneven friction-material transfer from the soft, comfort-biased OEM pad compound laying down patchy deposits that read as disc thickness variation, and rotors that do not seat flush on a corroded or debris-contaminated hub face, which forces measurable runout the moment the wheel is torqued. The car's mass and the low-dust, quiet pad choice make it unusually prone to the deposit version. The defining owner frustration is warranty: retailers routinely classify rotors and pads as wear items and refuse coverage even at very low mileage.

On the 2017-2023 Genesis G90, owners across model years report the 12V battery going flat after the car sits a few days. A common documented culprit is the radio/head unit continuing to draw current after shutdown, along with other parasitic draws that exceed the normal <50 mA key-off current. Leaving the key fob near the car can compound it. Frequent deep discharges shorten battery life and can leave the car unable to start.

On the 2019-2024 Genesis G90, on rear-seat-package G90s - the Ultimate and Prestige rear entertainment/executive rear seat configurations, and the second-generation 2023-plus cars - the rear-console touchscreen and the rear seat adjustment controls stop responding together. Because the rear display, the rear climate and audio controls and the rear seat motors share the console harness and control module in the center tunnel, one failure takes all of them out at once, which is the diagnostic tell that separates this from a front-infotainment software freeze. A 2023 owner reported the rear LED screen failing and the repair taking three weeks because the technicians had to remove both rear seats, the tunnel and the rear console to reach the harness and module. It is not a safety defect, but it disables the feature set that most justifies the trim's price.

On the 2017-2023 Genesis G90, water vapor accumulates inside the sealed headlamp assemblies and condenses on the inside of the lens, most often on one side only and worst after rain or a car wash. On the G90 and its Genesis siblings this is more than a cosmetic fog: because the units are full LED with sealed projector and DRL modules, standing moisture attacks the reflector coating over time, producing permanent pitting and discoloration that dims the beam, and in some reported cases water reaches the LED driver and kills a function outright, showing up as a dead low beam or a hyper-flashing turn signal. Owners across the Genesis forums report the same behavior on multiple models, and dealers frequently deflect it as normal venting behavior until it is documented as persistent.
