Fuel economy data from fueleconomy.gov (EPA / U.S. Dept. of Energy). Annual cost based on 15,000 mi/yr at 55% city driving and current fuel prices. MPG is U.S. gallons; L/100km converted. Ranges reflect the 4 tested variants for this model year.
Complaints for the 2017 Genesis G90 are spread across a relatively small set of reports, with engine and powertrain issues making up the bulk of what owners describe. On the engine side, owners report recurring check engine light illumination, with some tracing it to crankshaft position sensor replacements and valve cover gasket work, in at least one case the problem returned after the initial repair. A separate report describes an oil pressure sensor behaving erratically, causing the oil warning light to cycle on and off at varying speeds. Misfire complaints also appear, with owners noting the condition persisting even after spark plug replacement. A handful of owners describe difficulty switching between drive modes smoothly. One isolated report mentions the steering wheel failing to self-center after turns, requiring manual correction to return to a straight position.

By System
The 2017 Genesis G90 has 5 recalls, all centered on engine compartment fire risk: oil leaking from turbocharger supply pipes onto hot exhaust components, and a starter solenoid that can short-circuit and catch fire.
On the turbocharged 3.3-liter engine, the oil feed pipes and hose assemblies that supply the turbochargers can develop leaks, allowing oil to drip onto the exhaust manifold. Because the manifold runs extremely hot, that contact can ignite a fire in the engine bay. Earlier repair attempts under a prior recall did not fully resolve the issue for all affected vehicles, and some owners who had that earlier work done will need a second repair. Separately from the turbocharger oil lines, water can work its way into the starter solenoid and cause an electrical short. Unlike the turbocharger issue, which is limited to 3.3-liter turbocharged models, the starter solenoid defect affects a broader range of Genesis vehicles and can start a fire whether the car is running or parked with the engine off.
