NHTSA 5-Star Safety Rating
Electrical system complaints make up the largest share of owner reports for the 2018 Genesis G80, followed by steering and wheel-related issues. On the electrical side, owners describe headlight malfunctions, particularly the lights going completely dark or failing to dim when the manual dimmer is used while auto-dim mode is active, along with warning lights cycling on and off unexpectedly. Steering complaints include a range of handling and feel issues that owners noticed during normal driving. A smaller cluster of wheel-related reports rounds out the pattern. A handful of owners also describe airbag deployment concerns following collisions, including instances where airbags reportedly did not deploy as expected, and at least one owner flags conflicting vehicle identification data appearing across Genesis's own systems.

With Injuries
By System
The 2018 Genesis G80 has 6 recalls, with the most serious being multiple fire risks: oil leaking from turbocharger supply lines onto hot engine components, and both the ABS module and starter solenoid capable of short-circuiting and igniting a fire while parked or driving.
The turbocharger oil leak issues affect vehicles with the 3.3-liter V6 turbocharged engine, where oil can escape from deteriorating or loosely sealed supply pipes and reach hot exhaust components. The ABS module and starter solenoid fire risks are separate electrical faults, with water intrusion being the trigger for the solenoid issue. On the structural side, the windshield and rear window may have been bonded with incorrect primer, weakening their attachment over time and allowing either pane to detach while driving. There is also a passenger seat sensor concern: the occupant classification system can misread an empty front passenger seat as occupied by an adult, which means the airbag may deploy in a crash even when a child or infant is seated there, rather than staying suppressed as it should.

What can fail
The system that detects whether someone is sitting in the front passenger seat may incorrectly think an adult is there when the seat is empty. In a crash, if a child is actually in that seat, the air bag may deploy when it should stay off.
