2010 Hyundai Genesis Coupe 3.8 ProblemsUnwanted transmission downshifts
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.
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.
2010 Hyundai Genesis Coupe 3.8 RecallsPassenger Air Bag Only Partially Deploys In An Accident
The wiring connector to the occupant classification system (OCS) may become dislodged when the passenger seat is moved, resulting in the air bag system to default to only a single stage deployment of the passenger frontal air bag. Additionally, the air bag will not turn off as designed when there is a child in the front seat. Dealers will secure the OCS connector to prevent it from disconnecting free of charge to resolve the concern.
The affected vehicles are being recalled because the brake light switch can fail prematurely, resulting in the loss of brake light operation. Other systems that may be affected include: cruise control, push-button start, gear shifter, and Electronic Stability Control (ESC) system. Dealers will replace the brake light switch to correct this concern.
