What is the 2017-2022 Genesis G90 Air suspension failures — leaking air struts/bags, compressor burnout and rear sag?
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 stan… Repairs typically run $800-$4,000. Severity: high.
What is the 2017-2022 Genesis G90 Left turbocharger oil feed pipe cracks and leaks oil onto exhaust manifold, causing engine-compartment fire?
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 d… Repairs typically run $0-$800. Severity: high.
What is the 2022-2023 Genesis G90 Low-pressure fuel pump impeller deforms in heat, causing stalling (NHTSA Recall 24V282000)?
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 an… Repairs typically run $0-$0. Severity: high.
What is the 2017-2022 Genesis G90 Coolant leaks from water pump and thermostat housing?
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… Repairs typically run $350-$900. Severity: medium.
What is the 2017-2022 Genesis G90 Panoramic sunroof creaking, rattling and wind noise (loose/under-torqued frame bolts)?
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 ba… Repairs typically run $300-$3,000. Severity: medium.
What is the 2017-2022 Genesis G90 Front brake rotors develop pulsation and hot spots at low mileage, and dealers decline it as wear?
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… Repairs typically run $500-$1,500. Severity: medium.
What is the 2017-2022 Genesis G90 Soft-close power door cinching latch quits, leaving the door ajar or refusing to open?
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… Repairs typically run $100-$900. Severity: medium.
What is the 2017-2023 Genesis G90 Repeated 12V battery drain / dead battery from head unit and modules drawing power when parked?
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… Repairs typically run $250-$1,500. Severity: medium.
What is the 2017-2022 Genesis G90 Power trunk fails to close/latch or release, often due to lid misalignment?
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 (c… Repairs typically run $400-$1,500. Severity: low.
What is the 2019-2024 Genesis G90 Rear-console LCD and rear seat controls go dead, requiring a teardown of the rear seats and tunnel console?
