5/5 Overall
NHTSA 5-Star Safety Rating
Electrical system complaints dominate owner reports for the 2015 Genesis, with exterior lighting following as the second most-reported area. On the electrical side, owners describe a range of issues including unexpected battery failures, warning lights illuminating without clear cause, and intermittent failures of the headlight and wiper switches when set to automatic modes. Several owners report the engine shutting off unexpectedly while stopped or in drive, requiring a shift to park and a manual restart to get moving again. Exterior lighting complaints center on headlight behavior and related switch faults. Engine complaints are less numerous but include overheating and emissions-related fault codes appearing after repairs. A smaller number of owners separately describe the panoramic sunroof shattering outward while driving at highway speeds.

By System
The 2015 Hyundai Genesis has 15 recalls, the most serious being multiple fire risks: the ABS module can short circuit and ignite an engine compartment fire, and water entering the starter solenoid can cause a similar electrical fire, both possible even while the vehicle is parked.
The factory-installed Hankook Ventus S1 Noble 2 tires can crack or rupture at the sidewall, causing rapid air loss and loss of vehicle control. Water leaking into the rear combination lamp assemblies can corrupt the gear position signal, causing the instrument panel to show the wrong gear or delay engagement when shifting out of Park, potentially sending the car in an unexpected direction. On Genesis Coupe models with manual transmissions, the rear differential mounting bolts can loosen and allow the driveshaft to disconnect, cutting drive power entirely.
The front passenger seat sensor connector can pull loose when the seat is adjusted, causing the passenger airbag to deploy at the wrong force level in a crash. The instrument cluster on certain vehicles can display incorrect speed or show wrong warning light states. The parking brake warning light can fail to illuminate when the brake is applied due to a corroded switch, and some vehicles with the optional 7-inch LCD cluster can experience communication errors between the navigation head unit and the display.
