THE FORTH TIME WAS JUST THIS PAST WEEK WHEN DRIVING THE CAR ON A VERY BUSY ROAD AND IT HAPPENED AGAIN, THIS TIME SOMEONE HAD TO PUSH US OFF THE MAIN ROAD SO THAT WE DO NOT GET HIT. I TOOK THE CAR TO THE DEALERSHIP AGAIN AND THEY HAVE THE CAR RIGHT NOW AND I AM DRIVING A LOANER CAR. I CALL HYUNDAI AND STARTED A CASE AND THEY TOLD ME THAT IT IS UP TO THE DEALERSHIP TO DECIDE WHAT TO DO ABOUT MY CAR IF THEY CAN NOT FIND THE PROBLEM. I AM REFUSING TO DRIVE THE CAR BECAUSE I DO NOT KNOW WHEN THIS IS GOING TO HAPPEN AGAIN AND I AM AFRAID. WE HAVE BEEN VERY LUCKY UP TO NOW THAT WE HAVE NOT HAD AN ACCIDENT OR EVEN WORSE.

216V117000 · Visibility:windshield Wiper/washer:motor
Feb 29, 2016
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.
Consequence & remedy
Consequence: Inoperative wipers during inclement weather can decrease driver visibility, increasing the risk of a crash.
Remedy: 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.
13V489000 · Service Brakes, Hydraulic:fluid
Oct 29, 2013
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).
Consequence & remedy
Consequence: If the module corrodes, reduced brake effectiveness may result, increasing the risk of a crash.
Remedy: 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. Hyundai's recall number is 114.

Status: closed (inferred from source dates) · Service Brakes, Hydraulic; Service Brakes, Hydraulic:antilock/traction Control/electronic Limited Slip; Service Brakes, Hydraulic:antilock/traction Control/electronic Limited Slip:control Unit/module
On October 28, 2013, Hyundai Motor Company (Hyundai) submitted a Defect Information Report (DIR) to NHTSA describing a safety defect in the braking system of approximately 43,500 model year (MY) 2009 through 2012 Hyundai Genesis sedans (NHTSA Recall No. 13V-489).The Hyundai report indicates that the recalled vehicles may contain brake fluid that does not sufficiently inhibit corrosion on the zinc plating of control valve armatures in the Hydraulic Electronic Control Unit (HECU) module. The DIR indicated that, over time, the build-up of corrosion products may affect operation of HECU control valves, resulting in a low/soft brake pedal with reduced brake effectiveness, which may increase the risk of a crash.In October 2011, the HECU supplier notified Hyundai that the brake fluid used in production plants was causing corrosion of valve armatures in the control module.The supplier changed the coating of the valve armatures in late March 2012 to correct the problem in production vehicles.Hyundai's recall includes Genesis vehicles produced prior to the implementation of the HECU change.In March 2013, Hyundai initiated a Service Campaign (TL6) to replace brake fluid in the subject vehicles with brake fluid with better corrosion resistance properties.According to Hyundai's DIR letter, after PE13-033 was opened, the company noted that some of the vehicles serviced in the TL6 campaign subsequently required HECU replacement.This was an indication that internal corrosion had progressed enough to affect valve operation and brake performance, prompting Hyundai to conduct a safety recall.Hyundai's repair procedures for 13V-489 require brake system flushing and replacement in all recalled vehicles with a new fluid containing the necessary corrosion inhibitor.In addition, for vehicles produced prior to June 1, 2010, dealers will perform an inspection procedure to verify that the HECU is functioning properly and replace units that do not meet the test requirements.Hyundai indicated that, based on analysis of claim data, only vehicles produced prior to June 1, 2010 have been in service long enough to require the additional inspection/replacement of the HECU. Analysis of failure data reported to NHTSA and provided by Hyundai in response to ODI's information request letter for PE13-033 identified 756 complaints and 1,683 warranty claims for 30,114 subject vehicles produced prior to June 1, 2010, resulting in a complaint rate of 25.1 incidents per thousand vehicles (IPTV) and a claim rate of 5.6 percent.The MY 2009 vehicles, with the longest exposure times, experienced the highest complaint (33.5 IPTV) and warranty (7.0 percent) rates.For the 45,639 subject vehicles produced after June 1, 2010, ODI identified 13 complaints and 34 warranty claims, resulting in a complaint rate of 0.3 IPTV and a warranty claim rate of 0.1 percent, indicating that the brake fluid corrosion concern had not progressed far enough to result in significant rates of brake system performance symptoms in those vehicles.This investigation is closed.ODI will continue to monitor complaints to evaluate the effectiveness of Hyundai's recall.The VOQs noted in the Failure Report are: 10569231, 10560898, 10560495, 10559360, 10558279, 10558264, 10556964, 10556631, 10556577, 10556322, 10554988, 10554802, 10554122, 10552958, 10551817, 10551157, 10551110, 10551092, 10550791, 10550773, 10550431, 10549750, 10549634, 10549629, 10549567, 10549402, 10549376, 10549270, 10549228, 10549186, 10549021, 10548903, 10548823, 10548791, 10548737, 10548722, 10548716, 10548705, 10546565, 10544803, 10543663, 10542962, 10541959, 10541741, 10538208, 10537934, 10536652, 105354
