ON SEVERAL OCCASIONS SINCE 2/16/13 I HAVE BEEN HAVING INTERMITTENT PROBLEMS OF BRAKE PEDAL GRADUALLY GOING DOWN TO THE FLOOR AT A STOP LIGHT OR WHILE WAITING AT A STOP LIGHT THE BRAKES WOULD GRADUALLY LOSE PRESSURE AND THE CAR WOULD START CREEPING FORWARD. THIS HAS BEEN OCCURRING WHETHER I AM DRIVING 30 MPH ON RESIDENTIAL STREETS OR 70 MPH ON HIGHWAY (WHICH I STOPPED DOING!). MY HUSBAND ALSO DRIVES THE CAR AND EXPERIENCED THE SAME ISSUES. AFTER PUMPING THE BRAKES, I WAS FINALLY ABLE TO STOP. DRIVING IN INCLEMENT WEATHER HAS BEEN ALMOST HAZARDOUS. CAR TAKEN BACK TO DEALER (MARCH 7, 2013), HAD PART REPLACED, PICKED UP CAR ON MARCH 8, 2013 AND HAD TO TAKE THE CAR BACK THE VERY NEXT MORNING, MARCH 9, 2013, AND THE PROBLEM WAS WORSE THAN WHEN IT WAS TAKEN IN THE FIRST TIME. WHEN THIS STARTED HAPPENING, I WAS VERY AFRAID OF HAVING AN ACCIDENT, ESPECIALLY WHEN I NEVER COULD TELL IF MY BRAKES WOULD HOLD WITH JUST A SIMPLE STOP LIGHT. I HAVE SPOKEN WITH OTHER GENESIS 2009 OWNERS AND FOUND OUT THAT THIS PROBLEMS AS BEEN OCCURRING SINCE JULY 2012 AND HYUNDAI HAS BEEN MADE AWARE OF THIS PROBLEM AND CERTAIN DEALERS ARE NOT HANDLING THE REPAIRS IN A CUSTOMER FRIENDLY WAY, ESPECIALLY SINCE IS DEFINITELY A SAFETY ISSUE. *TR
AFTER SUDDEN DECELERATION, BRAKE PEDAL WENT SOFT. BRAKES CONTINUED TO OPERATE BUT LESS PREDICTABLY. INITIAL REPAIR OF BRAKE BOOSTER WORKED FOR A WEEK OR SO, THEN FAILED. REPLACEMENT OF ABS MODULE SEEMS TO HAVE FIXED THE PROBLEM. ALL WORK DONE UNDER WARRANTY. *TR

I WAS TRAVELING ON THE ON RAMP OF INTERSTATE I20 @ 45 MPH, APPLIED THE BRAKES AND NOTHING HAPPENED EXCEPT THAT THE PEDAL WENT RIGHT TO THE FLOOR, 7 MILES LATER ON THE EXIT RAMP AT ABOUT 70 MPH EXACTLY THE SAME THING HAPPENED AGAIN, TOOK THE CAR TO THE DEALER THAT EVENING AFTER WORK. THEY TOLD ME THE MASTER BRAKE CYLINDER HAD FAILED AND BECAUSE MY MILEAGE WAS 2,930 OVER THE 60K LIMIT IT WOULD NOT BE A WARRANTY REPAIR. I SAID "ARE YOU KIDDING ME?, YOU MUST CALL HNA THIS IS A SERIOUS PROBLEM". THEY MUST HAVE BECAUSE THEY REPAIRED IT "ONE TIME GOOD WILL FOR CUSTOMER SATISFACTION". MY CONFIDENCE IN THIS BRAND HAS GONE AWAY, THIS SHOULD BE A RECALL. *TR
THIS IS THE SECOND TIME THE BRAKE LIGHT DIODE HAS GONE OUT IN 29000 MILES. THERE IS NO WARNING LIGHT OR INDICATOR THAT THE BRAKE LIGHTS ARE OUT. BOTH TIMES IT WAS CAUGHT DURING AN OIL CHANGE. *TR

ON A TOTAL OF FOUR OCCASIONS NOW I HAVE HAD TOTAL BRAKE FAILURE--BRAKE PEDAL TO THE FLOOR WHEN MOVING. THE VEHICLE WENT TO THE DEALERSHIP AFTER THE FIRST INCIDENT. MULTIPLE PARTS WERE REPLACED. THE PROBLEM OCCURRED A SECOND TIME THEREAFTER. I CAPTURED IT ON VIDEO, AS THE PROBLEM WAS NOT DUPLICATING AT THE DEALERSHIP. THE DEALERSHIP DETERMINED THE BRAKE MASTER CYLINDER WAS FAULTY AND REPLACED IT. ALMOST EIGHT MONTHS TO THE DAY LATER (TODAY), THE SAME PROBLEM OCCURRED. IT IS INTERMITTENT AND RANDOM. THE BRAKE PEDAL LITERALLY PUSHES TO THE FLOOR, ALMOST AS IF NO FLUID IS IN THE LINES. THERE ARE NO RECALLS, TSBS, ETC. I HAVE POSTED THIS IN ONLINE FORUMS AND SOUGHT ANSWERS. SO FAR NO LUCK. IT IS ONLY A MATTER OF TIME BEFORE A CRASH AND POSSIBLY INJURY OCCUR. I AM VERY CLOSE TO PARTING WAYS WITH THE CAR. BRAKES ARE LIKE JET ENGINES; THEY REALLY NEED TO WORK ALL THE TIME. THANK YOU FOR YOUR ATTENTION TO THIS MATTER. *TR

ON DECEMBER 28TH I WAS DRIVING IN MY '09 V6 GENESIS ON THE INTERSTATE FOR ABOUT 20 MINUTES AND I TOOK A DOWNHILL EXIT WITH A STOP SIGN AT THE BOTTOM OF THE HILL. THANK THE UNIVERSE THAT THE ROAD WAS EMPTY BECAUSE AS I APPLIED THE BRAKES TO SLOW DOWN THEY WENT TO THE FLOOR AND THE CAR BARELY SLOWED DOWN AT ALL. AS I GOT CLOSER AND CLOSER TO THE STOP SIGN I HAD TO PUMP THE BRAKES ABOUT 4 MORE TIMES WITH THEM GOING ALL THE WAY TO THE FLOOR EACH TIME. THE CAR FINALLY SLOWED DOWN TO ABOUT 10 MILES AN HOUR. AS NOBODY WAS AT THE SIGN AT THE BOTTOM OF THE HILL I WAS ABLE TO COAST SLOWLY THROUGH THE STOP SIGN AND TURN LEFT TO USE THE EMERGENCY BRAKE TO COME TO A COMPLETE STOP. I THEN TURNED THE CAR OFF AND BACK ON TO TRY THE BRAKES AGAIN. THEY WENT TO THE FLOOR ABOUT 4 MORE TIMES AND THEN THE PRESSURE FINALLY RETURNED. THIS IS SOME SCARY STUFF SINCE I WAS ON THE HIGHWAY FOR ABOUT 20 MINUTES AND I KNOW FOR A FACT THAT I WOULD HAVE CRASHED INTO SOMEONE HAD I BEEN DRIVING DURING RUSH HOUR TRAFFIC AND THERE BEEN A LINE TO GET OFF THE INTERSTATE. I GOT THE CAR HOME SAFELY THAT AFTERNOON AND PARKED IT TO LEAVE THE COUNTRY FOR VACATION. I RETURNED ON THE NIGHT OF NEW YEARS DAY AND DROPPED THE CAR OFF ON THE MORNING ON JANUARY 2ND. THE DEALER SAID THEY WOULD LOOK INTO THE PROBLEM. I GOT A CALL FROM THEM YESTERDAY SAYING THEY CANNOT REPEAT THE PROBLEM (OF COURSE) BUT ALSO MENTIONED THAT THEY HAD TO REPLACE THE MASTER BRAKE CYLINDER ON A GENESIS JUST LAST WEEK FOR THE EXACT SAME PROBLEM. IRONICALLY ENOUGH I WAS SPEAKING WITH MY COWORKER ABOUT THIS (HE HAS A GENESIS) AND HE SAID HIS DAD HAS A GENESIS AND JUST HAD THE EXACT SAME PROBLEM 2 WEEKS AGO, TO WHICH THE DEALER REPLACED SOME ABS PARTS ON HIS CAR. PLEASE LOOK AT THIS FORUM TO SEE OTHERS WHO ARE EXPERIENCING PROBLEMS WITH THEIR BRAKES (HTTP://WWW.GENESISOWNERS.COM/HYUNDAI-GENESIS-FORUM/SHOWTHREAD.PHP?T=9926). *TR

Official recalls
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
