2009 Hyundai Genesis 3.8 Problems

Rough idle or hard start when cold

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.

Whine type noise from power steering

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.

Idle Fluctuation Concern

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.

Brake Lights

Due to an electrical circuit failure the brake lights may not work, increasing the risk of a crash. Dealers will repair the brake light switch circuit to correct this concern.

Reduced Braking Ability

The Hydraulic Electronic Control Unit (HECU) is part of the Anti-Lock braking system. The vehicles being recalled may have been assembled with brake fluid that does not protect the HECU from corrosion. If the module were to corrode, braking effectiveness could be reduced, increasing the risk of a crash. For vehicles manufactured prior to June 01, 2010, dealers will change the brake fluid and inspect the HECU, repairing it as necessary. For vehicles manufactured after June 01, 2010 dealers will flush the HECU assembly and brake system and change the brake fluid.
