2024 Genesis G90 Service and Repair Manual

This factory service and repair manual for the 2024 Genesis G90 addresses a four-door sedan built in two forms, Base and E-Supercharger, powered by a turbocharged 3.5L DOHC V6 or a turbocharged 3.5L DOHC V6 mild hybrid, both on gasoline. Since the two share displacement and layout, much of the engine mechanical work overlaps, and the manual is careful to mark where it does not — the added hybrid hardware, its own torque values and specifications, and the diagnostic routines that apply to it alone.

Known issues on the 2024 G90. Four recalls are listed for this year. Seat belt anchors that can detach leave an occupant without restraint in a crash. The driver assistance radar can register a vehicle that is not there and brake the car hard without warning. A software fault can blank the instrument panel display and its warning lamps, and fuel can leak where the fuel pipe meets the fuel rail. Three complaints are on record, one on the electrical system and one on forward collision avoidance — restraint, radar calibration and fuel line work all documented here.
