TL* THE CONTACT OWNS A 2012 HYUNDAI GENESIS. THE CONTACT STATED THAT THE BRAKE PEDAL TRAVELED TO THE FLOORBOARD WHEN IT WAS DEPRESSED. THE FAILURE OCCURRED SEVERAL TIMES. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THERE WAS A CORROSION BUILD UP CONCERNING THE BRAKE FLUID, WHICH AFFECTED THE HYDRAULIC ELECTRONIC CONTROL UNIT. THE MECHANIC REPLACED THE BRAKE PADS AND MASTER CYLINDER, BUT THE BRAKE PEDAL CONTINUED TO TRAVEL TO THE FLOORBOARD. THE DEALER (ALLEN HYUNDAI, 624 E PASS RD, GULFPORT, MS 39507, (228) 539-5555) WAS CONTACTED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE VEHICLE WAS NOT INCLUDED IN NHTSA ACTION NUMBER: PE13033 (SERVICE BRAKES, HYDRAULIC) AND NHTSA CAMPAIGN NUMBER: 13V489000 (SERVICE BRAKES, HYDRAULIC), BUT THE FAILURES WERE SIMILAR. THE MANUFACTURER WAS NOTIFIED. THE APPROXIMATE FAILURE MILEAGE WAS 74,380.

WHEN THE HEADLIGHT SWITCH IS IN THE ON POSITION, AS OPPOSED TO AUTO, THE HEADLIGHTS MAY OCCASIONALLY FLICKER. THIS PROBLEM IS EXACERBATED BY USING THE TURN SIGNALS. SOMETIMES THE HEADLIGHTS TURN OFF COMPLETELY WHEN THE TURN SIGNAL IS ACTIVATED AND I HAVE TO MOVE THE TURN SIGNAL STALK UNTIL THE LIGHTS COME BACK ON. AGAIN, THIS DOESN'T HAPPEN WHEN THE HEADLIGHTS ARE IN AUTO. IT'S MOSTLY NOTICEABLE IN THE RAIN WHEN THE HEADLIGHTS DON'T COME ON AUTOMATICALLY AND I HAVE TO TURN THEM ON MANUALLY. I FIRST NOTICED THE ISSUE IN 2015 WHEN THE VEHICLE WAS ABOUT 3 YEARS OLD.

FOLLOWING A HARD TURN WHICH ACTIVATED MY ELECTRONIC STABILITY CONTROL (ESC), I LOST ALL PRESSURE IN MY BRAKE PEDAL AND IT SUNK TO THE FLOOR. THIS IS FOLLOWING A NEAR-ACCIDENT IN WHICH I HAD TO ENGAGE MY ABS SYSTEM BY SLAMMING ON THE BRAKES TO AVOID AN ACCIDENT. EVER SINCE THAT ABS ACTIVATION, MY BRAKE PEDAL HAS NOT FELT THE SAME. IT TAKES MORE EFFORT TO STOP NOW AND YOU HAVE TO PUSH THE PEDAL FARTHER THAN USUAL TO GET BRAKE ACTIVATION. I CAN RECREATE THE PROBLEM BY GETTING THE ESC TO ACTIVATE AGAIN IF I SPIN THE TIRES ON A HARD TURN. IMMEDIATELY AFTER DOING SO, I WILL NO LONGER HAVE ANY BRAKING POWER OR PEDAL PRESSURE. HYUNDAI REFUSES TO ACCEPT RESPONSIBILITY FOR THIS BECAUSE EVEN THOUGH MY VEHICLE IS WITHIN THE AFFECTED PRODUCTION YEARS, THEY CLAIM MY VIN DOES NOT QUALIFY FOR THE RECALL. THE RECALL WAS CAMPAIGN 114 WHICH EVENTUALLY TURNED INTO A MANDATORY RECALL. THE POTENTIALLY AFFECTED YEARS RANGE FROM 2009-MARCH 28TH 2012. MY VEHICLE WAS MADE JANUARY 10TH, 2012. THEREFORE IT SHOULD QUALIFY BUT THEY CLAIM IT WILL NOT. I AM AFRAID FOR MY SAFETY AND HYUNDAI NEEDS TO OWN UP TO THEIR MISTAKES AND FIX MY PROBLEM BEFORE I DIE FROM IT. THE 3 INSTANCES I'VE HAD THE ISSUE HAVE ALL OCCURRED WHILE MAKING A HARD RIGHT TURN WITH LOW TRACTION AND THE ESC LIGHT FLASHES MEANING THE ABS WAS INDIRECTLY ACTIVATED. AFTER THIS TURN AND ESC ACTIVATION, THERE WILL BE NO PRESSURE IN THE BRAKES UNTIL IT GETS PUMPED SEVERAL TIMES. SOMETIMES I WILL HAVE NO BRAKE PRESSURE IN THE PEDAL UNTIL I'VE STOPPED 3 OR 4 TIMES AND PUMPED THE BRAKES.

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
