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.

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.
WHILE BRAKING AT A STOP LIGHT, THE BRAKE PEDAL WENT TO THE FLOOR AND I LOST ANTI-LOCK FUNCTION AND HAD TO PRESS HARD ON THE PEDAL TO STOP. THE PROBLEM PERSISTED FOR A DAY OR TWO, THEN WENT BACK TO NORMAL. AFTER ABOUT A WEEK, THE SAME PROBLEM OCCURRED. AFTER RESEARCHING THIS ISSUE, I FOUND NUMEROUS CARS HAD THE SAME PROBLEM, YET …

THE VEHICLE WAS IN MOTION IN A BUSY COMMERCIAL AREA. WHEN THE BRAKES WERE DEPRESSED THE PEDAL WENT TO THE FLOOR AND SLOWING OF THE VEHICLE WAS IMPAIRED. TO STOP THE VEHICLE REQUIRED PUMPING THE BRAKES TO RETURN SOME PEDAL PRESSURE. THE CAR WAS DRIVEN HOME AND OVER THE COURSE OF SEVERAL STOPS (PUMPING THE BRAKES) THE PEDAL FORCE RETURNED TO NEAR NORMAL. I AM MAKING AN APPOINTMENT TO HAVE THE CAR SERVICED BY A DEALER.

BRAKE PEDAL BEGAN TO REQUIRE MORE AND MORE TRAVEL TO ACHIEVE BRAKING EFFECTIVENESS. THERE WAS NO EVIDENCE OF A BRAKE FLUID LEAK. THERE WAS NO REDUCTION OF BRAKE FLUID IN THE RESERVOIR. THE ABILITY TO MODULATE BRAKING FOR CONDITIONS SUCH AS SLOW SPEED (PARKING LOT) DRIVING IS SIGNIFICANTLY IMPAIRED. THE ISSUE ALSO HAS REQUIRED A VERY HEAVY PRESSURE ON THE BRAKE PEDAL TO ALLOW THE ENGINE TO START (PUSH BUTTON IGNITION SWITCH). I HAVE LEARNED THAT HYUNDAI HAS IDENTIFIED AN ISSUE WITH BRAKE FLUID THAT FAILED TO PROTECT THE HYDRAULIC ELECTRONIC CONTROL UNIT (HECU). RESULTING CORROSION WITHIN THE BRAKE SYSTEM LEADS TO THE FAILURE MODE I AM EXPERIENCING. THIS ISSUE HAS HAPPENED ON A CAR DRIVEN BY AN 86 YEAR OLD WOMAN. THE SITUATION CAME ON OVER TIME, BUT BECAME VERY NOTICEABLE WITHIN THE LAST 6 - 8 MONTHS. THE CAR ONLY HAS 21.4K MILES ON IT.
MY BRAKE PEDAL BECAME SOFT AND SPONGE WITHOUT ANY WARNING SIGNAL. I HAD TO PRESS BRAKE PEDAL ALL THE WAY DOWN TO FLOOR IN ORDER TO STOP AND IT TOOK MUCH LONG DISTANCE TO STOP. HYUNDAI RECALLED MY CAR BACK ON 2013 AND CHANGED BRAKE FLUID. AT THAT TIME I HAD NO BRAKE PROBLEM. I THINK THEY MUST RECALL FOR THIS TERRIBLE MANUFAC…

MY BRAKE PEDAL BECAME SOFT AND SPONGE WITHOUT ANY WARNING SIGNAL. I HAD TO PRESS BRAKE PEDAL ALL THE WAY DOWN TO FLOOR IN ORDER TO STOP AND IT TOOK MUCH LONG DISTANCE TO STOP. HYUNDAI RECALLED MY CAR BACK ON 2013 AND CHANGED BRAKE FLUID. AT THAT TIME I HAD NO BRAKE PROBLEM. I THINK THEY MUST RECALL FOR THIS TERRIBLE MANUFACTURING DEFAULT BEFORE ANYONE GET INTO ACCIDENT.
BRAKE PEDAL GOES TO THE FLOOR WITH VERY LITTLE STOPPING POWER. IN AN EMERGENCY STOP SITUATION, THE CAR WOULD NOT BE ABLE TO STOP TO AVOID AN ACCIDENT.
WHEN APPLYING BRAKES WHETHER ON RESIDENTIAL STREETS, BACKING OUT OF THE GARAGE OR ON THE HIGHWAY THE BRAKE PEDDLE CONTINUES TO SINK TO THE FLOOR AND ONLY PROVIDES VERY LITTLE STOPPING POWER (SOMETHING LIKE A COASTING STOP).

WHEN APPLYING BRAKES WHETHER ON RESIDENTIAL STREETS, BACKING OUT OF THE GARAGE OR ON THE HIGHWAY THE BRAKE PEDDLE CONTINUES TO SINK TO THE FLOOR AND ONLY PROVIDES VERY LITTLE STOPPING POWER (SOMETHING LIKE A COASTING STOP). SINCE THIS RECENTLY STARTED HAPPENING I HAVE DISCOVERED THAT PUMPING THE BRAKES HELPS TO GET BETTER STOPPING RESULTS BUT IT IS NOW SCARY TO DRIVE. I HAD THE BRAKE FLUID REPLACED AS A RESULT OF HYUNDAI'S CAMPAIGN 114 RECALL IN JULY OF 2014, HOWEVER I AM NOW EXPERIENCING WHAT APPEARS TO BE CONSISTENT BRAKE FAILURE. I HAVE CONTACTED HYUNDAI CONSUMER AFFAIRS AND THEY BASICALLY STATED THAT BECAUSE I HAD THE CAMPAIGN 114 RECALL DONE THAT THERE IS NOTHING ELSE THEY CAN DO REGARDING THE POSSIBLE HECU MODULE FAILURE AS A RESULT OF DETERIORATION DUE TO THE DOT-3 BRAKE FLUID EXPOSURE. I ALSO FIND IT HARD TO ACCEPT THAT THE HECU MODULE WAS TAKEN OFF AND THE VALVES INSPECTED BY THE DEALER AS PART OF THE RECALL. I SINCERELY BELIEVE THAT THIS ISSUE WAS NEVER RESOLVED ON THE ORIGINAL 114 RECALL AND NOW I AM RESPONSIBLE FOR THE REPAIR COST AS HYUNDAI IS REFUSING TO COVER THIS UNDER WARRANTY. MY CAR HAS 74K MILES ON IT. SOMETHING NEEDS TO BE DONE AS ANYONE DRIVING ONE OF THESE VEHICLES IS IN VERY SERIOUS DANGER OF SEVERE INJURY OR DEATH TO THEMSELVES OR OTHERS AS THIS CAR IS NOT SAFE TO DRIVE AS A RESULT OF AN OVERSIGHT BY HYUNDAI. *TR

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

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
