ON SEPTEMBER 19, 2015, WHEN APPROACHING A RED LIGHT, THE BRAKE PEDAL WENT ALL THE WAY TO THE FLOORBOARD AND THE CAR WOULD NOT STOP. REPEATED PUMPING OF THE PEDAL FINALLY BROUGHT THE CAR TO A STOP. WITHIN AN HOUR A SECOND EVENT OCCURRED ON THE FREEWAY WHEN APPROACHING ANOTHER CAR FROM THE REAR. THE BRAKE PEDAL HAD NO RESISTANCE AND WENT ALL THE WAY TO THE FLOORBOARD. IT HAS NOT OCCURRED AGAIN. TWO DAYS LATER I TOOK THE CAR (CAREFULLY) INTO THE DEALER. THEY HAVE, AS YET, BEEN UNABLE TO REPLICATE THE PROBLEM (AS HYUNDAI REQUIRES FOR WARRANTY CONSIDERATION). HOWEVER, I WILL NOT DRIVE THIS CAR OR LET MY WIFE USE IT UNTIL THIS IS DIAGNOSED AND REPAIRED. IT IS EXTREMELY UNSAFE. THIS TYPE OF BRAKE FAILURE HAS BEEN NOTED REPEATEDLY IN THE 2009 HYUNDAI GENESIS. I AM STUCK WITH AN UNUSABLE CAR AND A MANUFACTURER WHO WILL NOT RECOGNIZE THE SEVERITY OF THIS ISSUE. THE DEALER DOES NOT WANT TO REPEATEDLY SUBJECT THEIR STAFF TO THE RISK OF AN ACCIDENT BUT HYUNDAI REQUIRES THE PROBLEM BE VALIDATED BY ANOTHER OCCURRENCE WHEN DRIVEN BY DEALER STAFF.

ON 9/16/15 THE BRAKES ON MY 2009 HYUNDAI GENESIS FAILED AND THE CAR WOULD NOT STOP AS THE BRAKE PEDAL SANK TO THE FLOOR. I FINALLY GOT THE CAR TO STOP WITH EXCESSIVE PUMPING OF THE BRAKES. ON 9/16/15 I BROUGHT MY CAR INTO JIM ELLIS HYUNDAI TO FIX THE PROBLEM. THE DEALER INSPECTED THE CAR AND COULDN'T REPLICATE THE ISSUE I HAD EXPERIENCED EARLIER IN THE DAY. THE DEALERSHIP RAN DIAGNOSTICS ON THE CAR AND DID NOT FIND ANY PROBLEMS AND NOW THE BRAKES SEEM TO BE WORKING FINE. MY CAR HAS 115,561 MILES. THIS IS THE SECOND VISIT TO THE DEALERSHIP FOR THIS PROBLEM. ON 04/30/15, I BROUGHT IN THE CAR FOR TWO RECALLS, ONE THAT INCLUDED A BRAKE FLUID FLUSH. A MONTH LATER, I HAD A SIMILAR INCIDENT WHILE DRIVING ON THE HIGHWAY THAT CAUSED ME TO LOSE BRAKE PRESSURE.AFTER A FEW DAYS THE PROBLEM SUBSIDED. I AM SERIOUSLY CONCERNED ABOUT THE SAFETY OF THIS AUTOMOBILE, ESPECIALLY AFTER READING SO MANY SIMILAR INCIDENTS ALREADY FILED WITH THE GOVERNMENT.

AT APPROXIMATELY 7:50AM ON MY WAY TO WORK, HEADING WESTBOUND ON RODEO RD AND WAS GOING TO MAKE A LEFT TURN AT CLOVERDALE MY CAR STALLED. DURING THE STALL THE ENGINE CUTOFF AND THE ELECTRICAL POWER IN THE CAR SEEMED TO RESET ITSELF. AS I WAS COMING TO A STOP, I COULD FEEL THE BRAKES NOT WORKING AND I PUT THE CAR INTO PARK AND TRIED TO RESTART THE ENGINE BY PUSHING ON THE START/STOP BUTTON. WHEN THAT DIDN'T WORK, ALL THE POWER IN THE CAR WENT OUT AND NOTHING WORKED, NO EMERGENCY LIGHTS, NO POWER ANYTHING. I CALLED ROADSIDE ASSISTANCE AND HAD THEM TOW TO THE NEAREST DEALERSHIP. THIS IS THE SECOND TIME THIS HAS HAPPENED. THE FIRST WAS ON SUNDAY NIGHT SEPTEMBER 6TH, 2015 AT AROUND 8PM IN SAN JOSE. I PUT THAT AS A COMPLAINT ON THIS SYSTEM AT THAT TIME.

GLOBAL AUTO MALL DIAGNOSED THE PROBLEM AND REPLACED THE MASTER BRAKE CYLINDER ASSEMBLY UNDER WARRANTY. MY CAR HAD 45,381 MILES ON IT AT THE TIME.

ON 8/31/15 I BROUGHT MY CAR INTO GLOBAL AUTO MALL DRIVING VERY SLOWLY TO THE DEALER, PUMPING THE BRAKES AT EVERY STOP ALONG THE WAY TO GET THE CAR TO STOP. MY CAR HAD 49,179 MILES ON IT AT THE TIME. GLOBAL AUTO MALL HAS STATED THAT AFTER RUNNING DIAGNOSTICS ON THE CAR THEY DID NOT FIND ANY PROBLEMS AND NOW THE BRAKES ARE WORKING FINE. A RECALL ON THE BRAKING FLUID THAT CAUSED CORROSION ON THE ABS MODULE WAS PERFORMED ON MY CAR ALREADY, BUT THERE IS NO WAY FOR THE TECHNICIAN TO ACTUALLY CHECK FOR CORROSION INSIDE THE ABS ASSEMBLY. I DO NOT FEEL THAT THE CAR IS SAFE TO DRIVE AND THE BRAKES ARE GOING TO FAIL AGAIN, AS NOTHING WAS REPAIRED ON MY VEHICLE.

314V713000 · Exterior Lighting:brake Lights:switch
Nov 7, 2014
Hyundai Motor America (Hyundai) is recalling certain 2009-2011 Hyundai Genesis vehicles manufactured April 30, 2008, to November 21, 2010, and 2011 Hyundai Equus vehicles manufactured July 31, 2010, to November 21, 2010. Due to a circuit failure, the stop lamps in the affected vehicles may not illuminate.
Consequence & remedy
Consequence: A following vehicle may not recognize that the vehicle is slowing or coming to a stop if the stop lamps on the vehicle do not illuminate as expected. There is an increased risk of a rear-end crash as a result.
Remedy: Hyundai will notify owners, and dealers will repair the stop lamp switch circuit, free of charge. Hyundai issued an interim notification to owners on January 6, 2015. The recall began on March 23, 2015. Owners may contact Hyundai customer service at 1-855-671-3059. Hyundai's number for this recall is 125.
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.

Apr 1, 2013
Hyundai Motor Company (Hyundai) is recalling certain model year 2006-2009 Accent, model year 2007-2011 Azera, Sonata and Sante Fe,2006-2011 Tucson, 2009-2011 Elantra Touring, 2007-2010 Elantra, 2008-2011 Veracruz, 2009-2011 Genesis, 2010-2011 Genesis Coupe, 2007-2008 Entourage, and 2006-2008 Tiburon vehicles. Originally, in April 2013, Hyundai recalled 1,059,824 model year 2007-2009 Accent and Tucson, model year 2007-2010 Elantra, model year 2007-2011 Santa Fe, model year 2008-2009 Veracruz, model year 2010-2011 Genesis Coupe, and model year 2011 Sonata vehicles. In September 2013, Hyundai informed the agency that it was adding more vehicles to this campaign, representing an additional 652,512 units. The total number of vehicles being recalled is now 1,712,336. In the affected vehicles, the stop lamp switch may malfunction. A malfunctioning stop lamp switch may cause the brake lights to not illuminate when the brake pedal is depressed or may cause an inability to deactivate the cruise control by depressing the brake pedal. Additionally, a malfunctioning stop lamp switch may also result in intermittent operation of the push-button start feature, affect the operation of the brake transmission shift interlock feature, preventing the shifter from being moved out of the PARK position and cause the Electronic Stability Control (ESC) malfunction light to illuminate.
Consequence & remedy
Consequence: Failure to illuminate the stop lamps during braking or inability to disengage the cruise control could increase the risk of a crash. Additionally, when the ignition is in the 'ON' position, the transmission shifter may be able to be moved out of Park without first applying the brake. This may lead to unintentional movement of the car which may increase the risk of a crash.
Remedy: Hyundai will notify owners, and dealers will replace the stop lamp switch, free of charge. The safety recall began on April 22, 2013. Owners may contact Hyundai at 1-800-633-5151. Hyundai's recall campaign number is 110.

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

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
