MY 2010 HYUNDAI GENESIS WAS RECALLED FOR A DEFECTIVE FAULTY BREAK SWITCH IN 2014 AND THE REQUIRED SERVICE WAS PERFORMED 7/30/15. THE FOLLOWING DAY I ENGAGED THE CRUISE CONTROL AT 75 MPH BUT ALMOST REAR ENDED THE CAR IN FRONT OF ME BECAUSE THE INTEGRATED SPEED CONTROL DID NOT ACTIVATE. THE CRUISE CONTROL ALSO TURNED COMPLETELY OFF AT TIMES. I'VE RETURNED THE CAR TWICE TO REMEDY THE PROBLEM AND WAS TOLD THEY COULD NOT FIND A SOLUTION AND HAVE REQUESTED ASSISTANCE FROM HYUNDAI. I WAITED ALMOST 2 MONTHS WITH NO WORD FROM HYUNDAI AND FINALLY WENT TO THE DEALERSHIP ON 9/22/15 AND WAS TOLD THEY WERE STILL WAITING FOR INSTRUCTION FROM HYUNDAI AND THEY NOW HAVE A SECOND CAR WITH THE SAME PROBLEM. I FEEL THIS IS VERY DANGEROUS AND WANT TO POST THIS LISTING BECAUSE I BELIEVE LIFES ARE AT STAKE AND OWNERS OF THESE VEHICLES WILL MORE THAN LIKELY BE TICKETED FOR CAUSING ACCIDENTS AND, WORSE CASE SCENARIO, BE CHARGED WITH VEHICULAR MANSLAUGHTER.

1) ALMOST HIT FROM ONCOMING TRAFFIC AT A STOP LIGHT, WHEN I WAS ATTEMPTING TO MAKE A LEFT HAND TURN. THE SIGNAL TURNED YELLOW SO I TRIED TO TURN LEFT BEFORE I REALIZED THE ONCOMING CAR WAS GOING TO RUN THE LIGHT. I TOOK MY FOOT OFF THE BRAKE AND HIT THE GAS TO MAKE A QUICK TURN TO AVOID THE ONCOMING CAR. THE CAR STALLED FOR A SECOND AS I PRESSED THE GAS INTO THE TURN, THEN KICKED INTO FULL POWER, SCREECHING THE TIRES. I THOUGHT THIS WAS A FLUKE BUT HIS SAME PROBLEM OF "STALLING" FOR A FEW SECONDS WHEN DEPRESSING THE BRAKE AND HITTING THE GAS AT TAKEOFF KEEPS HAPPENING INTERMITTENTLY. THIS IS A DANGEROUS ISSUE. WHEN NEEDING TO ACCELERATE QUICKLY FROM A STOP, THIS CAR HAS A SECONDS GAP FROM HITTING THE GAS TO THE CAR MOVING. I'VE ALMOST BEEN HIT TWICE BECAUSE OF IT. 2) THE HEADLIGHTS SWITCH OFF INTERMITTENTLY WHEN USING THE TURN SIGNALS TO CHANGE LANES OR TURN. THEY FLASH ONCOMING DRIVERS AS I CLICK DOWN TO TURN THEM ON BEFORE THE TURN, OR WHEN THE TURN SIGNAL CLICKS BACK AFTER THE TURN. THIS PROBLEM HAPPENS ALMOST EVERY TIME I DRIVE THE VEHICLE WITH THE HEADLIGHTS ON. THE LIGHTS HAVE SHUT OFF COMPLETELY FOR ABOUT 5 SECONDS WHILE I WAS DRIVING DOWN THE FREEWAY, IMPAIRING MY ABILITY TO SEE AT NIGHT. I HAD TO IMMEDIATELY PULL OVER ON THE FREEWAY IN AN UNSAFE LOCATION TO TURN THE LIGHTS OFF, THEN TURN THEM BACK ON TO CLEAR THE PROBLEM. 3) MY VEHICLE HAD THE BRAKE SWITCH REPLACED FROM THE 2013 RECALL. HOWEVER, PRESSING THE BRAKE STILL DOES NOT SHUT OFF THE CRUISE CONTROL WHEN DRIVING DOWN THE FREEWAY. I HAVE TO MANUALLY TURN IT OFF FROM THE BUTTON ON THE STEERING WHEEL. I LOVE THIS CAR, BUT I'M AFRAID TO DRIVE MY CHILDREN IN IT IF THESE PROBLEMS ARE NOT ADDRESSED. THIS VEHICLE IS UNSAFE AND IT IS GOING TO KILL OR SERIOUSLY INJURE PEOPLE. PLEASE INVESTIGATE THESE MECHANICAL PROBLEMS AND ISSUE THE APPROPRIATE RECALLS. *TR

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.

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
