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 fire risk: oil leaking from turbocharger feed pipes onto hot exhaust components, and a starter solenoid that can short-circuit and catch fire while the car is parked or in motion.
All five recalls affect fire-related defects across two systems. On the engine side, the left turbocharger oil feed pipe and its connections can deteriorate or develop a loose seal, allowing oil to drip onto the hot exhaust manifold and ignite. Prior repair attempts under an earlier campaign did not fully resolve this issue, and vehicles repaired under that earlier recall also require the current fix. These turbocharger oil leak recalls only affect vehicles equipped with the 3.3-liter turbocharged engine. Separately, water can enter the starter solenoid and cause an electrical short that starts a fire in the engine compartment, whether the vehicle is running or sitting parked.
