2019 Genesis G90

The 2020 G90's electronically controlled air suspension system is the most commonly reported problem area. The air suspension compressor can overheat and fail from excessive cycling caused by slow air leaks in the struts. Owners report the vehicle sagging overnight, a suspension malfunction warning on startup, and the compressor running loudly for extended periods trying to restore ride height.

Have the dealer perform a leak-down test on each air strut to identify which corner is losing pressure. Replace the leaking air strut(s) and inspect the compressor for overheating damage. If the compressor relay or motor has burned out from overwork, replace the entire compressor assembly. The air suspension is covered under the Genesis 5-year/60,000-mile warranty.

The 12.3-inch infotainment touchscreen can exhibit noticeable input lag, occasional screen blackouts, and graphical glitches where elements render incorrectly or overlap. Apple CarPlay connections are unstable, with frequent disconnections and failure to reconnect after starting the vehicle. The rear-seat entertainment screens may also experience synchronization issues.

Genesis released infotainment software updates to improve system responsiveness and connectivity stability. Have the dealer update the navigation and multimedia firmware to the latest version. For persistent CarPlay issues, ensure you are using an Apple-certified cable and try resetting the CarPlay connection by deleting the vehicle from your iPhone's CarPlay settings and re-pairing.

The G90's extensive array of luxury electronics creates a significant parasitic draw when the vehicle is parked. Owners report dead batteries after 3-5 days of non-use. The Advanced Driver Assistance System (ADAS) radar modules, the remote smart parking assist system, and the premium audio amplifier are common culprits for failing to enter proper sleep mode.

Have the dealer perform a parasitic draw test to identify which module is preventing the vehicle from entering deep sleep. Genesis released software updates for several control modules to reduce standby power consumption. If the battery has been deeply discharged multiple times, replace it with the correct AGM specification battery. Enabling 'Battery Saver' mode in the vehicle settings can help.

The heated, ventilated, and power-adjustable seats with massage function can experience various malfunctions. Common issues include the seat ventilation fans failing (particularly in the rear seats), the massage function motors burning out, and the seat memory function losing its saved positions. The driver seat may also develop a persistent squeak from the power seat track.

Have the dealer diagnose the seat control module for fault codes. The ventilation fan motor under the seat cushion can be replaced individually. For massage motor failures, the seat back cover needs to be removed to access the massage bladder motors. Lubricate the power seat track rails with the Genesis-specified lubricant to eliminate squeaking.

Despite the G90's luxury positioning, some owners report higher-than-expected road noise and NVH (Noise, Vibration, Harshness) intrusion at highway speeds, particularly from the rear wheel wells and A-pillar area. Wind noise around the frameless door windows and tire noise from the standard 19-inch or optional 20-inch wheels are the primary contributors.

Have the dealer inspect the door weatherstripping seals for proper seating and replace any that are not making full contact. Adding aftermarket sound-deadening material to the rear wheel wells can significantly reduce tire noise. Switching to a premium touring tire with a lower noise rating (look for tires with foam inserts like Continental ContiSilent or Pirelli Noise Cancelling System) can make a noticeable improvement.
