Hyundai Genesis 3.8 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.

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.

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.

My car seems to shudder or hesitate from time to time, mostly at higher speeds. Dealer checked transmission and throttle computer settings and found nothing wrong. Feels like brakes are engaging for a split second and then releasing.

Hyundai Genesis 3.8 Recalls

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.

The Smart Cruise is a very nice feature. The Lexicon stereo is the B...
