2009 Hyundai Sonata Electrical Problems

Your brakes are locking up while driving, leaving you stranded until the car sits for about 30 minutes to unlock—a serious safety hazard that's happened at red lights. Your brake lights stay on even when the car is off, and your ABS and ESC warning lights never turn off. The brake switch has been replaced and a stop lamp recall is pending, but you're also experiencing multiple electrical and door issues (broken door handles, non-functioning windows, doors that won't open) that compound the safety concern. The brake and electrical problems may require professional diagnosis and repair of the brake switch assembly, wiring harness, and related electrical components.

Your engine is leaking oil from the valve cover gasket onto the alternator, which can damage the alternator and cause your charging system warning light to turn on. If you keep driving with a disabled charging system, your engine may shut off unexpectedly, increasing the risk of a crash. The fix will likely involve replacing the valve cover gasket and inspecting the alternator for damage.

Your engine is leaking oil from the valve cover onto the alternator, which is damaging the electrical charging system. You may see a warning light on your dashboard, and your car's charging system may stop working. If you continue driving with a disabled charging system, your engine could shut off unexpectedly, which increases the risk of a crash. The fix will likely involve replacing the valve cover gasket and possibly the alternator.

Your fuel gauge stopped working correctly and showed a half tank when the car actually had no gas, causing the engine to shut down while driving at 60 mph. Your daughter had to pull over and the car wouldn't restart, requiring a tow to the dealer. The instrument panel was diagnosed as faulty, but the dealership didn't repair it and the manufacturer wouldn't help. A new instrument cluster or fuel level sender and gauge repair may be needed to fix this problem.

Your shark fin antenna fell off, and now your car's battery drains if you leave it parked for more than two days. Water is leaking into your car through the missing fin, damaging the interior carpets. The dealership quoted $700 to replace it, but multiple inspections haven't definitively identified the battery drain source—though it may be related to exposed components where the fin was removed. Fixing this will likely require replacing the shark fin antenna assembly and identifying the source of the electrical drain.

Your valve cover gasket is leaking oil onto the alternator, which can cause the alternator to fail and prevent your battery from charging properly. This can lead to your engine stalling and the car not starting afterward. Fixing this will likely involve replacing the valve cover gasket and possibly the alternator if it has been damaged by the oil.

All car systems flashed and car went completely dead. Nothing worked. First time it happened mechanic said alternator and battery had to be changed. A year and a half later exact same thing happened and again new mechanic says the alternator needs to be changed. BIG SAFETY ISUUE AS CAR DIED IN THE MIDDLE OF HIGHWAY WITH CARS GOING ALL AROUND ME TRYING TO AVOID ME. This is Second time the alternator has to be replaced with only 2000 miles on the car after the alternator was replaced the first time.

WAS DRIVING ON ACCESS ROAD AND THE ESC OFF LIGHT CAME ON AND THE CAR STARTED TO STALL- UNABLE TO ACCELERATE. HAD TO PULL TO SIDE OF THE ROAD ON WURZBACH PARKWAY. TOOK IT TO SHOP AND HAD CAM SHAFT, CRANKSHAFT SENSORS REMOVED AND REPLACED. HAD $700 OF OTHER WORK DONE AND CAR WORKED GREAT FOR 2 WEEKS. UNFORTUNATELY TODAY WHILE DRIVING HOME FROM ESC OFF LIGHT CAME ON AND CAR WAS UNABLE TO ACCELERATE. LUCKILY I GOT TO SAFETY BUT COULD'VE BEEN KILLED IF I WASN'T SO LUCKY... PRETTY RIDICULOUS PROBLEM TO HAVE ESPECIALLY AS SO MANY PEOPLE ARE REPORTING THE SAME PROBLEM...

CAR WON'T START, NOT EVEN MAKING SOUND OF IGNITION. THIS HAPPENED 3-4 TIMES AND TODAY ITS TOTALLY SHUT OFF. BATTERY LOOKS GOOD AND RADIO , LIGHTS AND ALL WORKING FINE BUT CAR NOT STARTING AT ALL. I READ ONLINE AND LOOKS LIKE THIS IS COMMON PROBLEM FOR ALL HYUNDAI SONATA 2008-2011 CARS.

CHECK ENGINE LIGHT IS ON. HECU INTERNAL FAILURE. ACTIVE DTC PRESENT: C1237 PRIMARY PRESSURE SENSOR SIGNAL. SENSOR FAILURE INSIDE THE ABS CONTROL CYCLE. VALUES AT PRESSURE SENSOR CHANGED FROM 0.3 BAR TO 78.0 BAR; NO CHANGE IN SUPPLY VOLTAGE. SUPPLY VOLTAGE CONSTANTLY AT 14V. HYUNDAI HAS MENTIONED THAT THERE ARE NO ACTIVE RECALLS AND THAT THIS PART IS LIFE THREATENING IF IT FAILS - BUT SINCE THE WARRANTY HAS EXPIRED THEY ARE SHYING AWAY. ONLINE THERE ARE SEVERAL KNOWN ISSUES WITH HYNDAI AND HECU. SPECIALLY FOR MODELS BEFORE 2009. ITS HARD TO BELIEVE THAT HYUNDAI IS NOT AWARE OF THIS PROBLEM AND SEEMS LIKE THEY ARE AVOIDING THEIR RESPONSIBILITY AND PLAYING WITH HUMAN LIFE. WOULD APPRECIATE IF THE GOVERNMENT CAN DO SOMETHING.

TL* THE CONTACT OWNS A 2009 HYUNDAI SONATA. THE CONTACT STATED THAT THE ELECTRONIC STABILITY CONTROL INDICATOR ILLUMINATED WHILE DRIVING 60 MPH. ALSO, THE VEHICLE JERKED AND STALLED, BUT WAS ABLE TO RESTART. ADDITIONALLY, THE ACCELERATOR PEDAL FAILED TO RESPOND WHEN IT WAS DEPRESSED. THE VEHICLE WAS TAKEN TO SEVERAL INDEPENDENT MECHANICS WHO REFERRED THE CONTACT TO HERITAGE HYUNDAI TOWSON (801 YORK RD, TOWSON, MD, 877-387-5495) WHERE IT WAS DIAGNOSED THAT THE CRANK POSITION SENSOR NEEDED TO BE REPLACED; HOWEVER, THE FAILURE RECURRED. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS 113,000.

THE ALARM WILL SOUND RANDOMLY WHILE DRIVING OR PARKED. WE ARE NOT SURE WHAT IS GOING ON. IT HAPPENS DOZENS OF TIMES A DAY AND ALARMS MY TEENAGE DRIVER. THE BUTTON IS NOT PUSHED, NOTHING IS TOUCHING THE CAR. JUST RANDOM. WE WANT THIS FIXED BECAUSE IT IS A SAFETY CONCERN, ESPECIALLY WHEN SHE IS DRIVING AND THE ALARM GOES OFF FOR NO REASON.

WHILE DRIVING THE ESC AND CHECK ENGINE LIGHT COMES THEN IT WILL ONLY LET ME 'COAST' ABOUT 5MPH.

TAKATA RECALL. I WAS TOLD THAT THE ELECTRICAL MODULE IS DEFECTIVE BY AUTOZONE,. WE WERE DRIVING DOWN THE HIGHWAY WHEN ALL OF A SUDDEN THE ENGINE LIGHT CAME ON. WE PULLED OVER TO CHECK THE USUAL STUFF LIKE OIL AND ANTIFREEZE AND OTHER FLUIDS. BUT ALL OF THEM WERE OK. WE TRIED TO LEAVE AGAIN WITH NO SUCCESS. WE HAD NO POWER. THE ENGINE WOULD TURN OVER BUT WHEN WE TRIED TO PRESS THE GAS NOTHING WOULD GO. SO WE STOPPED THE CAR WAITED FOR A WHILE AND THEN THE CAR STARTED. WE COUNTINUED OUR TRIP CAREFULLY, BUT THE CHECK ENGINE LIGHT WAS STILL ON. AFTER WE ARRIVED TO OUR DESTINATION I WENT TO AUTOZONE TO CHECK THE PROBLEM. THEY SAID THE ELETRICAL AND CPU MODULES ARE DAMAGED. THAT OF COURSE HAS ME A LITTLE WORRIED. WE HAVE ONLY HAD THE CAR FOR A YEAR SO IT COULDNT BE FOR THAT REASON.

THIS IS MY SECOND OFFICIAL COMPLAINT ABOUT THIS. I DROVE THROUGH A LARGE PUDDLE AND THE BATTERY LIGHT CAME ON, THE CAR SLOWED DOWN BUT RECOVERED AFTER THE LIGHT WENT OFF. I HAVE LOOKED AROUND AND MANY HYUNDAI CUSTOMERS, WITH DIFFERENT MODELS AND YEARS COMPLAIN OF THE SAME ISSUE. IS ANYTHING BEING DONE ABOUT THIS YET? OR DO DRIVERS HAVE TO DIE FIRST. PLEASE HELP US. -[XXX]PREVIOUS COMPLAINT # 10954232 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).'*JB

TL* THE CONTACT WAS REPAIRING A 2009 HYUNDAI SONATA. WHILE DRIVING VARIOUS SPEEDS, THE IGNITION WOULD INADVERTENTLY RESTART WHILE THE VEHICLE WAS IN MOTION. THE STARTER MOTOR COULD BE HEARD RE-ENGAGING. THE DRIVER WAS ABLE TO DRIFT TO THE SIDE OF THE ROAD, SHIFTED THE GEAR INTO NEUTRAL, AND RESTARTED THE VEHICLE CORRECTLY. AFTER SEVERAL MINUTES OF NORMAL OPERATION THE FAILURE RECURRED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC AND THEN TO A DEALER WHERE IT WAS DIAGNOSED THAT A NEW KEY CYLINDER AND IGNITION SWITCH NEEDED TO BE INSTALLED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS 48,000. UPDATED 04/12/17 *LJ *AS

FRONT ENGINE VALVE COVER GASKET LEAKED OIL ONTO ALTERNATOR CAUSING IT TO BECOME DAMAGED, WHICH LED TO POOR TRANSMISSION SHIFTING AND THEN COMPLETE LOSS OF ALL ELECTRICAL POWER.

FRONT ENGINE VALVE COVER GASKET LEAKED OIL ONTO ALTERNATOR CAUSING IT TO BECOME DAMAGED, WHICH LED TO POOR TRANSMISSION SHIFTING AND THEN COMPLETE LOSS OF ALL ELECTRICAL POWER.

CHECK ENGINE LIGHT CODE READS INTAKE VALVE CIRCUIT HAS LOW VOLTAGE. NOTICED REDUCED GAS MILEAGE ECONOMY AND POOR ENGINE PERFORMANCE.

SEVERAL DRIVER SIDE DOOR ELECTRONICS MALFUNCTIONS. LOCK BUTTON DOES NOT RESPOND WHEN TRYING TO LOCK DOORS. GAS CAP OPENER DOES NOT WORK. I HAVE TO MANUALLY OPEN MY GAS CAP THROUGH THE TRUNK. WINDOW AUTO CLOSE BUTTON NOT RESPONSIVE MOST OF THE TIME.

CAR STARTED AS USUAL AND I WAS DRIVING ON A CITY STREET GETTING READY TO GET ON THE HIGHWAY. ALL OF A SUDDEN THE CAR WOULD ONLY GO ABOUT 20 MPH AND REACH 1000 RPM. IT DIED SHORTLY THEREAFTER ON THE HIGHWAY FRONTAGE ROAD. ALL OF THE LIGHTS FOR ABS, BRAKES, CHECK ENGINE ETC. CAME ON BUT THE EMERGENCY FLASHERS WOULD NOT WORK SO I HAD TO KEEP PUMPING THE BRAKES SO NOBODY WOULD RUN INTO THE BACK END OF MY CAR. IT WOULD NOT RESTART SO I HAD TO HAVE IT TOWED TO THE DEALER. DEALER STATED VALVE COVER GASKET HAD LEAKED OIL ONTO THE ALTERNATOR AND RUINED IT. THAT IN TURN RUINED THE BATTERY. CAR WAS REPAIRED FOR $1400 INCLUDING THE TOW AND A RENTAL CAR. AFTER LOOKING AT HYUNDAI RECALLS, I NOTICED THE ONE FOR THE 2009 VERA CRUZ (NHTSA# 14V415000) IN WHICH 61,122 UNITS WERE RECALLED FOR THIS SAME PROBLEM. IN RESEARCHING THE AFFECTED VALVE COVER GASKET, I FOUND THE SAME ONE WAS USED ON MY 3.3L ENGINE THAT WAS LISTED AS DEFECTIVE ON THE 3.8L VERA CRUZ ENGINE. IF THAT PART WAS DEFECTIVE ON THAT VEHICLE, WHY WAS THE SCOPE OF THIS RECALL NOT EXTENDED TO COVER ALL POSSIBLE VEHICLES THAT COULD BE AFFECTED? I WOULD LIKE THE COST OF REPAIRS REFUNDED TO ME SINCE HYUNDAI OBVIOUSLY KNEW THIS PART WAS DEFECTIVE BUT DIDN'T ISSUE A RECALL TO COVER ALL AFFECTED VEHICLES. *TR

ON 10/08/2009 MY 209 HYUNDAI SONATA WENT INTO AN UNINTENDED ACCELERATION. AS SOON AS I PUT THE CAR INTO DRIVE IT BEGAN TO ACCELERATE. THE BRAKES DID NOT WORK AND I WAS ABLE TO SHIFT INTO NEUTRAL. I WAS ON A NARROW DIRT ROAD WITH LITTLE LIMITED OPTIONS AS TO WHERE TO STEER THE VEHICLE. I MISSED A BOULDER, GARAGE, AND TREE BEFORE HITTING THE SIDE OF A HOUSE. THE AMBULANCE WAS CALLED AND I WAS TRANSPORTED TO THE LOCAL EMERGENCY ROOM. I HAD A CONCUSSION, FRACTURED KNEE ALONG WITH A NUMBER OF BRUISES AND ABRASIONS. THE EMTS TOLD ME HOW LUCKY IF WAS SINCE THE AIR BAGS DID NOT DEPLOY.. AN INTERNET SEARCH, INCLUDING YOUR WEBSITE, NOTES THESE PROBLEMS GOING BACK SEVERAL YEARS. TOYOTA HAD THE SAME PROBLEM AND DID A RECALL. MY INJURIES WILL EXCEED THE LIMIT OF MY INSURANCE AND I WILL HAVE TO PURCHASE A CAR. I KNOW HOW LUCKY I WAS TO WALK AWAY. I AM SURE OTHERS HAD MORE SERIOUS INJURIES AND HIGHER EXPENSES. WHAT DOES IT TAKE TO FORCE HYUNDAI TO DO THE RIGHT THING?

THE POWER SIDE WINDOW BUTTON IS FLOPPY IT JUST STAYS DOWN AND YOU HAVE TO PULL IT BACK UP MANUALLY ITS LIKE THE SPRING IS BROKEN. THE HVAC MOTOR BLOWER DOESN'T ALWAYS BLOW I HAVE TO MESS WITH THE KNOB TO GET THE HEAT OR AC TO WORK.

TAMARA RECALL. MY SEAT WON'T MOVE BACK OR FORWARD . ELECTRICAL SWITCH.

BOUGHT CAR NEW , AT 30,000 MILE STARTER REPLACED [ COULD NOT TURN KEY IN IGNITION] . THAT WAS COVERED BY WARRANTY . AT 63,000 MILES IGNTION WENT [ AGAIN UNABLE TO TURN KEY TO START CAR ] AND I WAS STRANDED WITH VEHICLE.--THIS TIME APPROX $650.00 I FOR REPAIRS . I HAVE HEARD /READ THERE IS A HISTORY FO THIS KIND OF PROBLEM . HYUNDAI DID GIVE ME A $200.CREDIT TOWARD NEXT REPAIR . WITH MY AGE AND BEING WIDOWED I REALLY WOULD LIKE TO FEEL CONFIDENT THAT THIS CAR IS GOING TO BE SAFE FOR ME . I JUST DON'T THINK WITH THE AMOUNT OF MILEAGE THAT THESE PROBLEMS SHOULD HAVE EXISTED . ARE THEY USING INFERIOR PARTS ??

ESC LIGHT COMES ON INTERMITTENTLY COMMON PROBLEM WITH HYUNDAI. PREVIOUS RECALLS AND CURRENT RECALL ON SOME MODELS. I AM FILING A COMPLAINTS WITH NATIONAL SAFETY SO THAT A RECALL CAN BE EXTENDED TO MORE VEHICLES. HYUNDAI IS UNWILLING TO FIX THESE ISSUES WITHOUT A RECALL. WANT PEOPLE TO PAY OUT OF POCKET FOR SOMETHING THAT IS A MANUFACTURING DEFECT.

WHILE DRIIVING WITH THE SEAT BELT FASTENED....THE SEAT BELT LIGHT GOES OFF AND WHEN THE BRAKE IS APPLIED...IT DOESNT ALWAYS STOP....OR CATCH THE LIGHT GOES OFF WHETHER THE SEAT BELT IS FASTENED OR NOT. TLOW BEAM HEAD LIGHT ON DRIVERS SIDE GOES ON AND OFF AT TIMES...HAD CHECKED AND THE REPLY WAS IT MIGHT BE AN ELECTRICAL ISSUE.

HYUNDAI SONATA 2009 RED WARNING LIGHT FOR PASSENGER SEAL BELT STAYS LIT EVEN IF NO ONES SETTING THERE OR ONLY A PURSE, OR NO ONE SETTING THER. SO I HAVE TO PUT SEAL BELT INTO LOCK EVEN WHEN NO ONE SETTING THERE. SO I HAVE TO FASTEN SEAT BELT ALL THE TIME. WHEN DRIVING CAR ALL THE TIME HAVE TO KEEP IT FASTENED. ALSO WINDOW ELECTRIC SWITCH ON DRIVER SIDE MOST TIMES DOESN'T FUNCTION PROPERLY. THEN DEAL SOLD ME IT A FEW MONTHS AGO. I OPENED DOOR COVER TO SEE IF IT WAS A SWITCH PROBLEM & THERE WAS 2/12 INCHES OF DRIED DIRT IN BOTTOM OF DOOR PANEL. DEALER LARGE ONE IN SAN ANTONIO,TX, AT USED LOT SAY IT IS NORMAL. I SEEM TO THINK IT MIGHT HAVE BEEN FLOODED IN WATER HE SAY NO WAY IT NORMAL. SURE JOKES ON ME NOW PURCHASED AS IS DUMMY ME, IN LIMBO IN TX. CAR PAINT IS STARTING TO CHIP AS WELL WITH DEEP OPEN SCRATCHES WEIRD EVERY WASH SEEMS TO MAKE IT WORSE LOOKING.

THE ESC OFF LIGHT IS ALWAYS ON.

MY DRIVER SIDE DOOR LOCK BUTTON DOES NOT WORK. AS THE DRIVER, I AM UNABLE TO UNLOCK OR LOCK DOORS USING THIS BUTTON. INSTEAD I EITHER HAVE TO GET OUT OF MY SEAT TO UNLOCK THE OTHER DOORS. THIS IS A PERSONAL SAFETY HAZARD BECAUSE I HAVE NO CONTROL OVER MY DOOR LOCKS AND FORCED TO GET OUT OF MY SEAT OR VEHICLE TO EITHER LOCK OR UNLOCK DOORS WHEN THE CAR IS IN PARK.

TL* THE CONTACT OWNS A 2009 HYUNDAI SONATA. WHILE DRIVING 20 MPH, THE STABILITY CONTROL WARNING INDICATOR ILLUMINATED INTERMITTENTLY. THE VEHICLE WAS RESTARTED AND THE WARNING LIGHT SHUT OFF. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 115,000. THE VIN WAS NOT AVAILABLE.

THE BUTTON TO OPEN THE GAS CAP DOES NOT WORK.

!) CHECK ENGINE LIGHT HAS BEEN ON FOR ALMOST A YEAR..SHOP SAID IT WAS A GAS CAP PROBLEM..BOUGHT NEW CAP, NOT FIXED..STILL ON 2) FILLING CAR UP WITH GAS....VERY DIFFICULT TO FILL...KNOB KEEPS SHUTTING OFF GAS FLOW....ONCE AGAIN SHOP HAS NO GOOD ANSWER...... *TR

AFTER VEHICLE ENGINE WAS RUNNING THE STARTER MOTOR ENGAGED WHILE THE ENGINE WAS RUNNING. THE VEHICLE WAS IDLE PARKED THE SHIFT POSITION LEVER WAS IN THE PARK POSITION.THE STARTER MOTOR WILL ENGAGE ON IT'S OWN IN THE PARK POSITION AND IN THE NEUTRAL POSITION. THE STATER MOTOR WILL ALSO ENGAGE AND CRANK THE THE VEHICLE ENGINE IN THE DRIVE OR REVERSE POSITIONS THIS SYMPTOM DEVELOPED LATER. I HAD A CERTIFIED MECHANIC LOOK AT THE VEHICLE AND HE SAID THE IGNITION SWITCH WAS DEFECTIVE AND WILL HAVE TO BE REPLACED. I CHECK FOR RECALL INFORMATION ONLINE AND FOUND NO REFERENCE TO THE PROBLEM. *TR

THE CAR WAS IN THE DRIVEWAY WARMING UP AND CAUGHT FIRE IT BURNED UP THE STARTER AND STARTER ASSEMBLY, THE BATTERY WIRE HARNESS AND THE MANIFOLD. ALL OF THIS HAS TO BE REPLACED BEFORE WE CAN ASSESS ANY OTHER DAMAGES OR RUN A DIAGNOSTIC. *TR

TL* THE CONTACT OWNS A 2009 HYUNDAI SONATA. THE CONTACT STATE THAT THE VEHICLE HESITATED TO START AND ONCE IT DID, THE INSTRUMENT PANEL LIGHTS AND THE HEAD LIGHTS FAILED TO OPERATE. THE VEHICLE WAS TAKEN TO THE DEALER. THE TECHNICIAN DIAGNOSED THAT THE IGNITION LOCK CYLINDER WAS FAULTY AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE BUT NO ASSISTANCE WAS OFFERED. THE FAILURE MILEAGE WAS 59,000.

IGNITION IS STICKING, KEY WILL NOT TURN ON THE AUTO. IN 2011 WE STARTED HAVING TROUBLE WITH THE IGNITION ON THE CAR. WE HAD BEEN TO THE DEALER FOR THEM TO SPRAY, RECUT THE KEY AND EACH TIME IT WAS A TEMPORARY FIX. IN AUGUST OF 2011 THEY REPLACED THE IGNITION SWITCH. AGAIN WE HAD SOME PROBLEMS WITH THE KEY NOT WANTING TO START THE CAR. IN 2013 WE WENT BACK TO THE DEALER FOR THEM TO RECUT KEYS, AND FIX THE IGNITION BECAUSE THE KEY WAS NOT TURNING THE CAR ON, YET AGAIN. IN 2014 THE CAR WAS STRANDED IN A PARKING LOT AFTER THE CAR WAS AT THE DEALER FOR THEM TO FIX THE IGNITION PROBLEMS. THEY CLEANED THE IGNITION OUT AGAIN. WE HAD TO CALL A LOCK SMITH TO COME AND WORK ON THE IGNITION TO GET THE CAR STARTED. THIS FIXED THE CAR FOR ABOUT 3 MONTHS. AGAIN THE CAR WAS STRANDED AT A BUSINESS. WE CALLED THE LOCK SMITH AGAIN AND THIS TIME IT HAD TO BE TOWED TO THE DEALER FOR REPAIRS. TO DATE: WE HAVE BEEN TO DEALERS 15+ TIMES FOR WORK ON OR REPAIR TO THE IGNITION. OTHER ASPECTS LIKE THE LOCKING MECHANISM, OR OTHER PARTS THAT ARE INVOLVED IN MAKING THE KEY TURN HAS NEVER BEEN ADDRESSED, I AM TOLD THAT THE COST WILL BE 250.00+ FOR AN ISSUE THAT STARTED BEFORE THE WARRANTY RAN OUT. *TR

PROBLEM WAS WITH THE SWITCH ON MY CAR. WHEN I TURNED THE CAR ON IT MADE A STRANGE SOUND FOR A COUPLE OF MONTHS, IT WOULD ONLY HAPPEN ONCE OR TWICE A MONTH. WHEN IT BECAME MORE FREQUENT AND BEGAN TO MAKE THE SOUND A COUPLE OF TIMES WHEN I PUT THE CAR IN PARK, I TOOK MY HYUNDAI BACK TO THE CAR DEALER. THEY CLAIMED IT WAS THE STARTER. MY HUSBAND AND HIS MECHANIC SAID IT SOUNDED MORE LIKE THE SWITCH. THEY WANTED TO CHARGE ALMOST 500.00 DOLLARS TO FIX THE PROBLEM. MY HUSBAND BOUGHT THE SWITCH FOR ABOUT $15.00 DOLLARS AND HIS MECHANIC PUT IT ON. I HAVE NOT HAD ANY PROBLEMS SINCE. I DO NOT KNOW IF ANY ONE ELSE HAD THIS PROBLEM. *TR

TAKING MY CAR FOR THE FIRST OIL CHANGE SINCE I BOUGHT IT AND THE CAR STALLED WHILE IN NEUTRAL WAITING FOR AN OIL CHANGE. RESTARTED WITHOUT A PROBLEM. IT HAS ALSO TRIED TO STALL WHILE DRIVING SEVERAL TIMES SINCE, MORE FREQUENT THAN BEFORE. IT'S ALSO STALLED IN STOP AND GO TRAFFIC. MY CHECK LIGHT ONLY COMES ON FOR A SPLIT SECOND WHEN THE CAR TRIES TO DIE, BUT AFTER THAT, IT'S JUST FINE. BROUGHT IT TO 3 DEALERSHIPS THAT TOLD ME THAT NOTHING WAS WRONG WITH MY CAR. I BOUGHT AN OBDII SCANNER AND FOUND TROUBLE CODES P0335 AND P0108. TOOK IT TO THE DEALER AGAIN AND THEY STILL COULDN'T FIND A CODE. MY CAR HAS ALMOST STALLED WHILE TRYING TO CROSS A BUSY INTERSECTION AND NO ONE WANTS TO EVEN TRY TO HELP ME. *TR

THE INCIDENT IS SIMILAR TO NHTSA ID# 10508953 WHICH STATED THERE WAS A GRINDING NOISE AFTER STARTING THE CAR. I EXPERIENCED THE SAME MALFUNCTION BUT SOMETIMES THE GRINDING DOESN'T STOP UNTIL THE ENGINE IS TURNED OFF. IT DOESN'T HAPPEN EVERYTIME THE ENGINE IS STARTED BUT I ALSO HAD OTHER PROBLEMS WITH THE IGNITION SWITCH. A FEW TIMES THE ENGINE STARTED WHILE THE KEY WAS JUST TURNED TO THE "ON" POSITION. AFTER HEARING OF ALL THE IGNITION SWITCH PROBLEMS WITH GM VEHICLES, I THOUGHT THIS SHOULD BE HANDLED BY HYUNDAI AS A RECALL BECAUSE IT IS DEFINITELY AN UNSAFE SITUATION. I HOPE THE NHTSA WILL TAKE ACTION ON THIS MATTER. THE VEHICLE OWNERS SHOULD NOT HAVE TO PAY FOR DEFECTIVELY MANUFACTURED COMPONENTS NO MATTER HOW OLD THE VEHICLE. *TR

ON OCTOBER 27 2013, THE DASH BOARD LIGHTS AND THE BACK ILLUMINATING LIGHTS, GLOVE COMPARTMENT AND OVER HEAD LIGHTS WENT OUT, I TOOK IT TO A CAR REPAIR SHOP AND THEY CHANGED OUT THE DIMMER SWITCH, WHICH KEPT BURNING OUT,SMOKE HAS COME OUT OF THE DASH BOARD AND IT SMELLED LIFE FIRE, I PULLED OVER AND CALLED THE DEALER. THIS IS A SAFETY ISSUE I AM NOT ABLE TO DRIVE THE CAR AT NIGHT AND I AM AFRAID THE CARE MIGHT CATCH FIRE. AFTER CHANGING IT OUT 4 TIMES, THE MECHANIC TOLD US TO TAKE IT TO THE DEALER.WE DID TAKE THE CAR TO THE DEALER AND $700.00 LATER THEY STILL DON'T KNOW WHAT THE PROBLEM IT, SO I HAVE FILED A CASE WITH THE CORPORATE OFFICE, THE CAR HAS HAD SOME ELECTRICAL PROBLEMS BEFORE, BUT IT HAS BEEN FIXED BECAUSE THEY HAVE BEEN RECALLS. THE DEALER DOES NOT KNOW WHAT TO DO AND THEY WANT US TO TAKE THE CAR SOMEWHERE ELSE. THE DEALER IS NO HELP, THEY SUGGESTED WE JUST BUY A NEW CAR!!! *TR

MY ESC OFF AND CHECK ENGINE LIGHTS CAME ON. MY MECHANIC INDICATED IT WAS DUE TO A BAD BRAKE LIGHT SWITCH AS MY REAR BRAKE LIGHTS AND CRUISE CONTROL DID NOT WORK. HE REPLACED THE BRAKE LIGHT SWITCH BUT A COUPLE DAYS LATER THE CHECK ENGINE LIGHT CAME BACK ON. THE COMPUTER LISTED A DIFFERENT CODE, STATING THE BRAKE LIGHT SWITCH IS NOT COMPATIBLE, BUT THE REAR BRAKE LIGHTS WORK OFF AND ON. AWAITING FOLLOW UP WITH MY MECHANIC AS HE WAS GOING TO CHECK WITH HYUNDAI.

TL* THE CONTACT OWNS A 2009 HYUNDAI SONATA. THE CONTACT STATED UPON STARTING THE IGNITION THE ENTIRE INSTRUMENT PANEL AND HEADLIGHTS FAILED TO FUNCTION. THE FAILURE OCCURRED INTERMITTENTLY. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER THREE TIMES. THE DEALER REPAIRED THE VEHICLE DURING THE THIRD DIAGNOSTIC TEST; HOWEVER, THE INTERMITTENT FAILURE PERSISTED. THE MANUFACTURER WAS NOT NOTIFIED OF THE DEFECT. THE APPROXIMATE FAILURE MILEAGE WAS 23,000. THE VIN WAS UNAVAILABLE.

AROUND FEB OF THIS YEAR, MY CAR BATTERY DIED AND I GOT IT REPLACED WITH A NEW ONE. SOON AFTER I STARTED EXPERIENCING AN ADDITIONAL GRINDING NOISE THAT WOULD OCCUR SOMETIMES AFTER START UP. UPON INVESTIGATION, I WAS TOLD IT WAS THE STARTER BY HYUNDAI. I TOOK MY CAR TO MY MECHANIC HOWEVER AND WAS TOLD THAT IT WAS THE IGNITION SWITCH SELECTOR, THAT IT HAD GONE BAD AND THAT IT NEEDED TO BE REPLACED. I HOPE THIS SOLVES THE PROBLEM. *TR

WHILE THE CAR WAS RUNNING, SHE NOTICED THE SPEEDOMETER NEEDLE WAS AT ZERO READING WHILE THE CAR WAS DOING AT LEAST 25 MILES PER HOUR. SHE TURNED AROUND AND DROVE AN OLDER CAR INSTEAD. OVER THE WEEKEND, I DROVE THE HYUNDAI SONATA AROUND BUT THE SPEEDOMETER PROBLEM DID NOT SHOW UP. BUT THE FOLLOWING MONDAY AFTERNOON, I EXPERIENCED THIS SPEEDOMETER PROBLEM FIRST HAND. I NOTICED THE CAR WOULD ACCELERATE FROM STOP WITH THE NEEDLE EITHER SLIGHTLY GOING UP OR NOT AT ALL. I WAS AT LEAST GOING 25 MILES PER HOUR ON AN EXPRESSWAY. THE NEEDLE CONTINUED TO BE STUCK AT ZERO UNTIL I HAD TO APPLY THE BRAKE, AND THEN MOMENTARILY, THE NEEDLE WOULD BOUNCE UP BETWEEN 20-30 MPH BEFORE GOING BACK TO ZERO AGAIN. *TR
