WHILE DRIVING THE CAR TO WORK I NOTICED THAT THE BRAKES SUDDENLY WENT SOFT. THE CAR WOULD SLOW DOWN WHEN I HIT THE PEDAL BUT IN ORDER TO STOP THE CAR I HAD TO NEARLY PRESS THE BRAKE PEDAL TO THE FLOOR. LATER IN THE SAME DRIVE THE BRAKES FUNCTIONED NORMALLY. I DIDN'T NOTICE ANOTHER PROBLEM WITH THE BRAKES FOR AT LEAST A WEEK UNTIL MY DAUGHTER DROVE THE CAR AND NEARLY HIT SOMEONE BECAUSE THE BRAKES DID NOT STOP AS SHE EXPECTED. I NOTICED THAT IF I PUMPED THE BRAKE PEDAL THE PRESSURE WOULD RETURN FOR A WHILE BUT THEN IT WOULD GO SOFT AGAIN ONCE I DROVE IT AND THE PEDAL IS PRESSED. AT THE POINT THE PRESSURE WOULD NOT RETURN CONSISTENTLY AND IT WAS QUESTIONABLE IF THE CAR WOULD STOP I TOOK IT TO THE DEALERSHIP. THE SERVICE DEPARTMENT INFORMED ME THAT THE ABS MODULE HAS FAILED AND THAT IT WOULD BE A MATTER OF TIME BEFORE MY BRAKES WOULD TOTALLY FAIL. THERE WAS NO INDICATION OF THE ABS MODULE FAILING. NO ABS LIGHT; NO BRAKE LIGHT; NO CHECK ENGINE LIGHT. FOR THIS TO AFFECT THE SAFETY SYSTEM OF THE CAR I WOULD EXPECT THERE TO BE SOME TYPE OF INDICATION OF FAILURE. THE DEALER INFORMED ME THAT THE MODULE IS $2200 FOR REPLACEMENT! THE CAR IS ONLY 5 YEARS OLD WHY WOULD THE ABS MODULE FAIL IN SUCH A RELATIVELY NEW VEHICLE?

I PURCHASED THE CAR IN JANUARY 2017 AFTER 2 MONTHS OF HAVING THE CAR THE WINDOWS WOULD NOT GO UP. I WOULD HAVE TO WAIT HOURS FOR IT TO START BACK WORKING. THE SUSPENSION WAS LOW FOR A FEW WEEKS THEN IT WOULD SLOWLY COME BACK UP. BASICALLY MY WHOLE CAR HAS ELECTRICAL PROBLEMS BACK UP CAMERA GOES BLACK, THE ODOMETER HAS DEAD PIXELS, CAR EXTREMELY SLUGGISH, THE CAR SHAKES AND KILLS ALOT. ALSO WHEN I TURN THE HEATED SEATS ON IT TURNS OFF WITHIN 2 MINUTES. IT IS SO MUCH THE CAR IS DOING TO SAY THIS CAR HAS A CLEAN CARFAX.
I WAS DRIVING TO MY WORK. I SAW RED LIGHT SIGNAL AND STEPPED ON BRAKE PEDAL. BUT THE PEDAL JUST WENT DOWN VERY SOFTLY WITHOUT STOPPING MY CAR. MY CAR STOPPED AFTER I PRESSED FULL FORCE ON BRAKE PEDAL. BY THE TIME MY CAR STOPPED IT ALREADY PASSED 15 FEET FROM THE STOP LINE WHERE I HAD TO STOP.
THIS HAS BEEN AN ONGOING ISSUE, I KNOW OTHERS HAVE REPORTED A SIMILAR PROBLEM. WHEN COMING TO A STOP IN OUR 2012 GENESIS 3.8L THE ENGINE WILL SHUT OFF WITHOUT ANY WARNING.

THIS HAS BEEN AN ONGOING ISSUE, I KNOW OTHERS HAVE REPORTED A SIMILAR PROBLEM. WHEN COMING TO A STOP IN OUR 2012 GENESIS 3.8L THE ENGINE WILL SHUT OFF WITHOUT ANY WARNING. THIS HAS HAPPENED MORE THAN A DOZEN TIMES AT THIS POINT. MY WIFE TOOK IT TO THE DEALER WHO SAID THIS ISSUE COULDN'T BE DUPLICATED. THE CAR HAS DIED IN TRAFFIC AND WHEN GOING AROUND A CURVE. POWER STEERING IS LOST WHEN THIS OCCURS MAKING IT A BIT NERVE WRACKING. THIS IS AN ISSUE HYUNDAI NEEDS TO ADDRESS BEFORE SOMEONE IS INJURED OR 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

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
