Known Problems

Hyundai Genesis Coupes equipped with navigation units may suddenly stop playing audio from all speakers. This includes sound from CD players, radio, navigation, satellite radio, and telephone calls. All other features may still function properly.

This fault requires no part replacement, and is a software glitch that can be rectified by a 'hard reset'.

To perform the hard reset, simply disconnect the vehicles negative battery terminal, wait 15 minutes, and reconnect the negative battery terminal.

The theft system alarm may sound for no apparent reason. The is commonly caused by a faulty hood closed switch. A new, slightly taller switch is available to correct this concern.

A whine type noise may be noted from the power steering pump. This can be caused by a clogged reservoir which can aerate the power steering fluid. Cleaning the reservoir screen will restore proper fluid flow, reducing the noise.

A creak or tick type may be noted from the sunroof when closed. This is commonly caused by drying of the sunroof weather strip. Our technicians recommend lubing the sunroof weatherstrip with a dry silicone lube to correct this issue.

When the shift lever is in D3 and sport mode is selected the transmission may downshift unexpectedly when the throttle is depressed. Our technicians tell us there is a transmission control module (TCM) software update available to correct this concern.
