Known Problems

A rough idle or hard starting condition may develop, most noticeable when the engine is cold, with fault code P161B stored in the powertrain control module (PCM). Our technicians tell us that a PCM software upgrade is available to correct this concern.

Hyundai Genesis 3.8 models 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.

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.

An idle fluctuation may be noted, the Check Engine Light may or may not illuminate. Replacing the throttle position sensor and updating the powertrain control module (PCM) software will commonly correct this concern.

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.
