TL* THE CONTACT OWNS A 2010 HYUNDAI GENESIS COUPE. AFTER BEING PARKED FOR THREE MONTHS, THE VEHICLE FAILED TO START. THE CONTACT LOOKED UNDER THE HOOD AND FOUND RODENT EXCREMENT, FOOD PARTICLES, AND NOTICED THAT THE WIRING HARNESS WAS CHEWED THROUGH. THE VEHICLE WAS TOWED TO BOB BAKER HYUNDAI (LOCATED AT 5285 CAR COUNTRY DR, CARLSBAD, CA 92008, (760) 929-4900) WHERE IT WAS DIAGNOSED THAT THE STARTER NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED; HOWEVER, THE CONTACT STATED THAT THE MECHANIC FAILED TO PROPERLY DIAGNOSE THE VEHICLE. THE REPAIR COST $1,300. THE CONTACT STATED THAT THE CHECK ENGINE AND TIRE PRESSURE MONITORING SYSTEM WARNING INDICATORS ILLUMINATED AFTER THE VEHICLE WAS REPAIRED. ADDITIONALLY, THE CONTACT WAS INFORMED THAT THE ENGINE'S WIRING HARNESS WAS SOY-BASED. AFTER THE VEHICLE WAS REPAIRED, IT FAILED TO OPERATE AS INTENDED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 90,773.

ENGINE CRANKS NORMALLY ATTEMPTING TO START. WHEN FAILED TO START, THE 'START' BUTTON IS PUSHED TO STOP THE ATTEMPT. TRIED AGAIN. TOOK 3 ATTEMPTS TO FINALLY START. ONCE STARTED THE ENGINE REVS AT HIGH RPM'S. WHEN PUT IN 'D' THE CAR LURCHES AND ACCELERATES WITHOUT PUSHING GAS PEDAL. IF THE CAR IS TURNED OFF AFTER STARTING AND RESTARTED, FAST ACCELERATION IS ELIMINATED. CAR HAS ULTIMATELY STARTED, BUT THE FEAR IS IT WILL GET WORSE AND ULTIMATELY FAIL TO START STRANDING THE DRIVER. CAR RUNS PERFECTLY IN NORMAL DRIVING ON THE HIGHWAY. THIS HAS OCCURRED ALMOST DAILY FOR 90 DAYS. HYUNDAI SERVICE: TAKEN TO HYUNDAI ON TWO OCCASIONS. THEY SAY THEY COULD NOT DUPLICATE PROBLEM AND NO COMPUTER ERROR CODES GENERATED. STUMPED! CAN DO NOTHING IF PROBLEM CAN'T BE DUPLICATED BY SERVICE TECH! KEEPING QUIET? NEW CONDITION 4/26/18! CAR HAS SHUT DOWN TWICE AT A STOP LIGHT, 4/26 AND 4/29. FEAR OF SHUTTING DOWN WHILE IN TRAFFIC AS REPORTED IN USER FORUMS. HYUNDAI USER FORUMS: DOZENS OF OWNERS DISCLOSE THAT THE PROBLEM IS WIDESPREAD ACROSS YEARS AND MODELS. REPORT THAT HYUNDAI DENIES THERE IS AN ISSUE WITH PROBLEMATIC STARTING AND STALLING AT LOW SPEEDS AND HIGH SPEEDS! OWNERS REPORT FEAR OF SERIOUS ACCIDENT IF THE CAR STALLS ON THE HIGHWAY, ENTERING TRAFFIC OR MAKING TURNS ACROSS TRAFFIC.

TL* THE CONTACT OWNS A 2010 HYUNDAI GENESIS COUPE. WHILE DRIVING APPROXIMATELY 20 MPH, THE VEHICLE LOST POWER AND RESTARTED AFTER ONE ATTEMPT. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. A LOCAL DEALER WAS NOT CONTACTED. THE MANUFACTURER ADVISED THE CONTACT THAT THERE WERE NO RECALLS AND A CASE WAS OPENED. THE FAILURE MILEAGE AND VIN WERE UNKNOWN.

HELLO NHTSA ADMINISTRATOR, I BOUGHT A NEW HYUNDAI GENESIS IN MARCH 2010. AROUND AUGUST 2010, I HAD A SMALL FENDER BENDER IN THE PARKING LOT. TO KEEP WARRANTY INTACT ON THE CAR, HYUNDAI INSISTED THAT THE WIRING HARNESS ON THE CAR BE REPLACED, WHICH I DID FOR APPROXIMATELY $5000. SINCE THEN, I HAVE HAD MULTIPLE ELECTRONIC ITEMS GO BAD IN THE CAR. I REPLACED SOME OF THESE AT MY OWN EXPENSE. BUT THE PROBLEM HAS GOTTEN WORSE WITH SOME EXPENSIVE ELECTRONIC COMPONENTS GOING BAD OVER THE LAST 2 YEARS. IN NORMAL CIRCUMSTANCES, THESE COMPONENTS SHOULD NOT GO BAD OVER THE LIFE OF THE CAR, AND CERTAINLY NOT AT A FREQUENCY THAT THEY HAVE FAILED IN MY CAR. I ATTRIBUTE THESE FAILURES TO BAD/DEFECTIVE JOB DONE DURING WIRING HARNESS REPLACEMENT. BUT HYUNDAI HAS REFUSED TO ACCEPT RESPONSIBILITY SINCE THE CAR IS OUT OF WARRANTY. BELOW IS A LIST OF THE BAD COMPONENTS, APPROXIMATE DATE OF THE COMPONENT GOING BAD, WHETHER IT IS REPLACED/FIXED AND APPROXIMATE EXPENSE TO FIX THEM 1. TELESCOPIC STEERING WHEEL--2015--REPAIRED AS PART OF WARRANTY 2. POWER SWITCH ASSEMBLY DRIVER'S SEAT--JAN 2016--$236.19--PAID OUT-OF-POCKET TO GET IT REPLACED 3. JOG DIAL ASSEMBLY--OCT 2016--$1031.70--PAID OUT-OF-POCKET TO GET IT REPLACED 4. FRONT CABIN DOME LIGHT ASSEMBLY--FEB 2017--$376.91--PAID OUT-OF-POCKET TO GET IT REPLACED 5. SMART CRUISE CONTROL--MAR 2017--NOT REPLACED--DEALERSHIP GAVE ME A QUOTE OF ~$4500 TO REPLACE 6. PASSENGER CABIN DOME LIGHT ASSEMBLY--AUG 2017--NOT REPLACED--$4500 ESTIMATE TO REPLACE 7. MULTI DISC CD PLAYER--FEB 2018--NOT REPLACED--$1000 ESTIMATE TO REPLACE I WOULD LIKE NHTSA TO INVESTIGATE HYUNDAI FOR THIS MATTER AND FORCE THEM TO PAY FOR REPAIRS. AS A CONSUMER, I FEED CHEATED AND BEING FORCED TO DOUBLE PAY FOR REPAIRS - ONCE FOR THE WIRING HARNESS REPLACEMENT AND NOW FOR ALL PROBLEMS ATTRIBUTED TO IT. SINCERELY, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

THE TIRE PRESSURE MONITORING SYSTEM (TPMS) DISPLAYS ERRONEOUS TIRE PRESSURE READINGS DURING COLD WEATHER CLIMATES DESPITE HAVING THE CORRECT PSI OR ADDING AIR TO REACH AN ULTIMATE PSI READING. THIS HAS BEEN AN ISSUE WITH OTHER MODELS OF HYUNDAI VEHICLES WITH THE TPMS FEATURE ACCORDING TO OTHER OWNERS. *TR

THE NAVIGATIONAL/RADIO/ANTENNA SYSTEM COMPLETELY SHUTDOWN WITHOUT ANY POWER RANGING FROM 2HRS TO A FULL DAY. I ALSO HAVE RESEARCHED THAT OTHER 2010S OF THIS MAKE & MODEL HAS EXPERIENCED THE SAME ELECTRICAL ISSUE JUST AS WELL. *TR

I BEGAN HAVING THIS ISSUE 10 DAYS AGO WITH MY 2010 GENESIS COUPE. THE CONCERN I HAD WAS NOT ONLY WAS THE INTERIOR FLICKERING BUT IT RESULTED IN MY RUNNING NIGHT BRAKE LIGHTS NOT WORKING. I TOOK THE CAR TO THE DEALER I'M AT 62K MILES JUST OUT OF WARRANTY. THEY RAN DIAGNOSTIC AND THOUGHT IT WAS A LOSE BRACING FOR THE WIRES. I PICKED IT UP AND THE ISSUE BEGAN AGAIN. I TOOK IT IN 4 DAYS AGO THEY THEN SAID IT WAS A FUSE SWITCH ISSUE AND REPLACED IT BUT THE ISSUE CONTINUED. THEY THEN SAID IT MAY BE A FUSE BOX ISSUE COUPLE OF HUNDRED $$ OR WORST CASE A MAIN ISSUE WITH TOTAL WIRING FROM INTERNAL FUSE BOX AND FUSE BOX IN THE ENGINE AREA WHICH COULD RUN $2K! BUT NO DEFINITE ANSWER TO WHAT WAS CAUSING THIS. THE HYUNDAI REPRESENTATIVE SAID THEY EVEN HAPPEN TO HAVE A SENIOR ELECTRIC ENGINEER ON LOCATION THAT DAY AND HE COULDN'T PINPOINT EXACTLY THE PROBLEM. *TR

THE BRAKE LIGHTS ON THE 2010 HYUNDAI GENESIS (AND POSSIBLY OTHER YEARS/MODELS HYUNDAI VEHICLES) HAVE VARIOUS PROBLEMS WITH THE BRAKE LIGHTS FAILING TO WORK. THIS IS VERY DANGEROUS NOT ONLY TO THE HYUNDAI GENESIS DRIVER, BUT ALSO FOR ANY DRIVER FOLLOWING BEHIND THE CAR. THERE HAS BEEN VARIOUS FACTORY RECALLS FOR THE 2010 HYUNDAI GENESIS BRAKES INCLUDING ONE THAT CAUSES THE BRAKE LIGHTS NOT TO WORK DUE TO A BRAKE SWITCH FAILURE: HTTP://WWW.CARS.COM/HYUNDAI/GENESIS/2010/RECALLS HOWEVER THE PARTICULAR PROBLEM MY CAR AND OTHER GENESIS OWNERS HAVE REPORTED DOES NOT HAVE A FACTORY RECALL FOR IT, EVEN THOUGH IT POSES THE SOME OF THE SAME SAFETY ISSUES THAT THE BRAKE SWITCH FACTORY RECALL HAD. HTTP://GENESISOWNERS.COM/HYUNDAI-GENESIS-FORUM/SHOWTHREAD.PHP?T=3269 THE ROOT CAUSE IS DIODE THAT FAILS WHICH CAUSE THE BRAKE LIGHTS NOT TO WORK. (THIS IS DIFFERENT THAT THE BRAKE SWITCH FACTORY RECALL.) I DON'T KNOW HOW MANY MONTHS I DROVE WITHOUT HAVING BRAKE LIGHTS. MY STATE INSPECTION WAS IN JANUARY 2014. A DRIVER THAT WAS BEHIND MY CAR INFORMED ME MY BRAKE LIGHTS DIDN'T WORK IN MAY 2014. I HAD MY CAR TOWED TO THE DEALER DUE TO THE DANGER OF DRIVING WHEN THE CAR'S BRAKE LIGHTS DON'T WORK. APPARENTLY HYUNDAI KNOWS ABOUT THE ISSUE (ACCORDING TO THE ABOVE LINK) : TECHNICAL SERVICE BULLETIN 09-BE-023, STOP LAMP Z01 DIODE INSPECTION PROCEDURE, APPEARS TO DESCRIBE THE LOCATION AND PROCEDURE FOR TROUBLESHOOTING OF THE DIODE BUT DESCRIBES THE ISSUE AS " . . . VEHICLES MAY EXPERIENCE THE STOP LAMPS BLINKING ON AND OFF EVEN WHEN BRAKES ARE NOT APPLIED." WHY IS THERE NO FACTORY RECALL FOR THIS PROBLEM? IT CAN CAUSE SERIOUS ACCIDENTS WHICH COULD LEAD TO FATALITIES. *TR

TL* THE CONTACT OWNS A 2010 HYUNDAI GENESIS. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 45 MPH, THE VEHICLE STALLED WITHOUT WARNING. IN ADDITION, THE VEHICLE FAILED TO START ON NUMEROUS OCCASIONS. THE VEHICLE WAS TAKEN TO THE DEALER NUMEROUS TIMES FOR THE FAILURE. THE DEALER REPLACED THE BATTERY, THE KEY FOB, THE SMART KEY MODULE AND THE IGNITION LOCK MODULE HOWEVER, THE FAILURE REMEDY FAILED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 83,000 AND THE CURRENT MILEAGE WAS 84,700.

TOOK MY 2010 GENESIS IN FOR SERVICE...BRAKE STOP LIGHTS WERE NOT WORKING. REPLACED DEFECTIVE SWITCH. TOOK MY SAME CAR IN FOR STATE INSPECTION ON SEPTEMBER 9, 2014, BRAKE LIGHTS NOT WORKING AGAIN. REPLACED DEFECTIVE SWITCH MYSELF BECAUSE OF 2 HOUR DRIVE TO DEALER AND THE SAFETY ISSUE INVOLVED WITH DRIVING VEHICLE. SOMETHING NEEDS TO BE DONE! THESE SWITCHES SHOULD NOT FAIL THIS OFTEN.... THIS IS A VERY SERIOUS SAFETY ISSUE. WE DON'T KNOW HOW LONG THIS SWITCH WAS NOT WORKING SINCE THERE IS NO WAY TO TELL WHEN YOU ARE DRIVING THE VEHICLE... THANKS!

TL* THE CONTACT OWNS A 2010 HYUNDAI GENESIS COUPE. THE CONTACT STATED THAT WHILE DRIVING 80 MPH, THE STEERING SEIZED AND THE ENGINE RPMS INCREASED GREATLY. THE CONTACT ALSO MENTIONED THAT THE TRACTION WARNING LIGHT ILLUMINATED INTERMITTENTLY. THE VEHICLE WAS TAKEN TO A DEALER WHERE THE MECHANIC STATED THAT THE ECU FAILED AND THE ABS CONTROL MODULE WOULD NEED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS 78,758.

THIS VEHICLE HAS A FEATURE WHERE THE DOOR MIRRORS ANGLE DOWN WHEN THE CAR GOES INTO REVERSE, AND THEN COMES BACK TO NORMAL VIEWING POSITION WHEN YOU CHANGE TO ANY OTHER GEAR (E.G. PARK, DRIVE). INTERMITTENTLY, ONE MIRROR (DRIVER OR PASSENGER) DOES NOT COME BACK UP. THE DRIVER WILL NOT LIKELY NOTICE THE MIRROR NOT RETURNING TO IT NORMAL VIEWING POSITION UNTIL HE USES THE MIRROR AGAIN, LIKE WHEN HE CHANGES LANES. I HAVE HAD THIS HAPPENED ALMOST A DOZEN TIMES TO ME. I HAVE ALMOST SIDE SWIPED OTHER DRIVERS ON THREE OCCASIONS. I HAVE BEEN TO THE DEALERSHIP NINE TIMES SO FAR, BUT THEY HAVE NOT FIXED IT. IT IS HARD TO DIAGNOSE BECAUSE IT DOESN'T HAPPEN OFTEN. MANY OTHER HYUNDAI GENESIS OWNERS HAVE SEEN THIS ISSUE. HTTP://WWW.GENESISOWNERS.COM/HYUNDAI-GENESIS-FORUM/SHOWTHREAD.PHP?T=10483. *TR

SINCE PURCHASED USED FROM A HYUNDAI DEALER IN 2011 WITH JUST 11,123 MILES & FULL WARRANTY, THIS VEHICLE HAS HAD "INTERMITTENT OPERATION OF THE PUSH-BUTTON START FEATURE, INTERMITTENT ABILITY TO REMOVE THE VEHICLES SHIFTER FROM THE PARK POSITION, ILLUMINATION OF THE ESC'(ELECTRONIC STABILITY CONTROL) INDICATOR LAMP IN THE INSTRUMENT CLUSTER, INTERMITTENT INTERFERENCE WITH OPERATION OF THE CRUISE CONTROL FEATURE, OR INTERMITTENT OPERATION OF THE STOP LAMPS" AS CITED IN CAMPAIGN 110 RELEASED BY HYUNDAI ON MARCH 29,2013. I HAVE BROUGHT IT TO THE DEALERS SERVICE DEPARTMENT ON 11 SEPARATE OCCASIONS, FOR THE ABOVE LISTED ISSUE -TO TWO SEPARATE DEALERS- AND WHILE BOTH UTILIZED THE HYUNDAI WARRANTY TO THE FULLEST EXTENT, TO REPLACE EVERYTHING FROM MY RADIO, TO TRANSMISSION MODULES, TO WHEEL CYLINDERS, NONE OF THESE ISSUES FIXED THE PROBLEM.WHEN I SPOKE TO HYUNDAI LAST WEEK REGARDING RECALL CAMPAIGN 110, I WAS ASSIGNED A CASE NUMBER, BUT I RECEIVED A CALL THE NEXT DAY THAT MY CASE WAS BEING REJECTED BY THE REGIONAL OFFICE.WHEN I BROUGHT IT TO THE DEALER FOR THE RECALL REPAIR THIS WEEKEND, THEY INSISTED THAT THEY WOULD HAVE TO CHARGE ME FOR THE VISIT, DESPITE MY COMPLAINT BEING THE ONE LISTED IN THE RECALL.I FEEL THAT HYUNDAI SHOULD HONOR THEIR RECALL AND ADDRESS THIS PROBLEM IN MY CAR AT THEIR EXPENSE UNTIL THEY RECTIFY THE ISSUE CITED IN THE RECALL, DESPITE THE FAULTY PART HAVING BEEN REPLACED THROUGH MY FACTORY WARRANTY MULTIPLE TIMES, AND PRIOR MY RECEIVING NOTICE OF THE RECALL. HYUNDAI MOTOR CORPORATION SHOULD DO WHAT IS REQUIRED TO GET THE CAR THEY SOLD ME TO BE IN SAFE OPERATING CONDITION, AND THEY REFUSE TO DO SO. *TR
