2012 Hyundai Genesis Service and Repair Manual
Hyundai wrote different specifications for the Genesis sedan across its production run, which is why this factory service and repair manual is tied to the 2012 model year specifically: every clearance, torque value and service sequence in it is the one Hyundai published for your exact year, engine and trim, not a figure carried over from an earlier or later Genesis.

Known issues on the 2012 Genesis. Two recalls are on federal record for this model year. The first covers the hydraulic brake fluid and reaches certain model year 2009-2012 Genesis vehicles; if the module corrodes, reduced brake effectiveness may result, increasing the risk of a crash. The second covers the windshield wiper motor on certain 2012 Genesis vehicles manufactured August 1, 2011, to April 30, 2012, where inoperative wipers during inclement weather can decrease driver visibility. Owners have filed 362 complaints for the year and Hyundai has issued 96 technical service bulletins.
From a brake-hydraulic service to a wiper-motor diagnosis or a scheduled service on either V8 or the 3.8 V6, it keeps you on Hyundai's own procedure and the correct specification for your specific 2012 Genesis.
Hyundai Motor America (Hyundai) is recalling certain model year 2012 Genesis vehicles manufactured August 1, 2011, to April 30, 2012, and 2011-2013 Equus vehicles manufactured July 10, 2011, to June 12, 2012. The windshield wiper motor cover seal on the affected vehicles may degrade allowing corrosion on the wiper motor's circuit board. The corrosion can cause intermittent or total loss of wiper function.
Inoperative wipers during inclement weather can decrease driver visibility, increasing the risk of a crash.
Hyundai will notify owners, and dealers will replace the wiper motor cover and seal, free of charge. The recall began on April 22, 2016. Owners may contact Hyundai customer service at 1-800-633-5151. Hyundai's number for this recall is 140.
Hyundai is recalling certain model year 2009-2012 Genesis vehicles manufactured April 30, 2008, through March 28, 2012. The vehicles may contain brake fluid which does not protect against corrosion of the Hydraulic Electronic Control Unit (HECU).
If the module corrodes, reduced brake effectiveness may result, increasing the risk of a crash.
Hyundai will notify owners and instruct them to bring their vehicle to a dealer for service. Hyundai will inspect the HECU module for proper operation, and will replace the modules as necessary. Hyundai will replace the factory brake fluid in those vehicles that have not previously had the factory brake fluid replaced. These repairs will be done free of charge. The recall began on December 24, 2013. Owners may contact Hyundai at 1-800-633-5151 or by email at consumeraffairs@hmausa.com. Hyun
