I HAD 53,000 MILES ON THE VEHICLE. DRIVING ON HIGHWAY MY STEERING WHEEL GOT STIFF AND TOOK AN EXIT. MY VEHICLE WAS IN SMOKE AND TOWED TO NEAR BY HYUNDAI SERVICE CENTER. I WAS TOLD THAT TIMING BELT GOT BROKEN AND THAT IN-TURN CAUSED DAMAGE TO ENGINE PISTONS. HYUNDAI DECLINED TO OFFER ANY ASSISTANCE, AND SAID I HAVE TO PAY FOR ALL THE REPAIRS. I HAD TO SELL THE CAR FOR A FEW HUNDRED DOLLARS, BECAUSE THEY ASKED ABOUT 7K TO FIX A REPLACEMENT ENGINE.

MY FATHER IS CURRENTLY LOOKING AFTER MY VEHICLE AND WHILE HE WAS DOING ROUTINE CHECKS WHEN WENT TO DEPRESS THE BRAKE PETAL IT SANK ALL THE WAY TO THE FLOOR. HE LATER TOOK IT TO A MECHANIC WHO THEN BLEED THE SYSTEM A FEW TIMES ONLY TO FIND OUT THAT THE FRONT RIGHT BRAKE AND REAR LEFT BRAKE ARE OPERATING AS NORMAL. AS IT WOULD TURN OUT, HOWEVER, HYUNDAI ISSUED A RECALL FOR THIS BUT ONLY FOR THE GENESIS SEDANS AND NOT THE COUPES. HYUNDAI RECALL #114 AND NHTSA RECALL #13V489000 STATE THE BRAKE FLUID THE MANUFACTURE USES DOES NOT PROTECT THE H.E.C.U. OR HYDRAULIC ELECTRONIC CONTROL UNIT (A.K.A. ABS CONTROL UNIT) AGAINST INTERNAL CORROSION. SO THE INTERNAL VALVES WILL CORRODED AND PREVENT THE BRAKES FROM OPERATING PROPERLY. IN MY 2011 GENESIS COUPE THIS IS CURRENTLY THE ISSUE. OTHER COUPE OWNERS ARE HAVING SIMILAR ISSUES WHERE THEY CAN'T STOP THE CAR PROPER AND/OR THE BRAKE PETAL SINKS TO THE FLOOR AT RANDOM TIMES WHILE DRIVING SLOW OR AT HIGHWAY SPEEDS AND THE BRAKE DON'T OPERATE PROPERLY OR AT ALL! THE MANUFACTURE SEEMS TO BE AWARE OF THE ISSUE BUT WON'T DO ANYTHING ABOUT IT. REPLACING THE MASTER CYLINDER AND COMPLETELY BLEEDING THE SYSTEM DOESN'T HAVE ANY AFFECT FOR THE ISSUE. TO REPLACE THE UNIT, I'M LOOKING AT ROUGHLY $3,200 OF MY OWN MONEY TO REPLACE THE H.E.C.U DUE TO DEFECTIVE BRAKE FLUID THAT HAS CORRODED THE INTERNALS. THE CAR HAS BARELY BEEN DRIVEN WITH LESS ABOUT 30K MILES ON IT. THIS A GRAVE SAFETY CONCERN AND HYUNDAI NEEDS TO ADDRESS THE ISSUES FOR NOT JUST THE SEDANS BUT THE COUPES AS WELL! IF I OR THE DRIVER OF MY CAR NEEDED TO MAKE AN EMERGENCY STOP THERE IS NO TELLING IF THE BRAKES WOULD OPERATE IN THAT MOMENT AS THEY SHOULD. INJURY OR DEATH COULD OCCUR FOR NOT JUST THE DRIVER BUT OTHER CASUALTIES THAT COULD BE PREVENTED IF HYUNDAI FIXES THIS ISSUE FOR ALL HYUNDAI GENESIS COUPES. BRAKE OPERATION IS VASTLY IMPORTANT IN ALL VEHICLES. THIS PROBLEM IS SERIOUS.

16V722000 · Air Bags:sensor:occupant Classification
Oct 7, 2016
Hyundai Motor America (Hyundai) is recalling certain model year 2010-2016 Genesis Coupe vehicles manufactured December 12, 2008, to June 11, 2016. The electrical harness connector for the front passenger seat Occupant Classification System (OCS) may dislodge when the seat is moved.
Consequence & remedy
Consequence: In the event of a crash necessitating deployment of the passenger frontal air bag, the disconnected OCS would, by default, cause the first stage, and only the first stage, of the air bag to deploy, whether there is a child seat in the front seat and the bag should not deploy or if the crash is severe and both stages should deploy. Either scenario increases the risk of injury to the front seat occupant.
Remedy: Hyundai will notify owners, and dealers will secure the OCS connector to prevent it from disconnecting, free of charge. Parts are not currently available and a second letter will be sent to owners when parts are available. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 151.
13V113000 · Exterior Lighting:brake Lights:switch
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.

PE13033 · Brake Hydraulic Control Module Failure
Opened Oct 17, 2013 · Closed Apr 4, 2014
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
