2009 HYUNDAI SONATA Electrical System Problems

Passenger seat belt doesn’t click in. Miss fire Poor acceleration Exhaust leak Power lost Mechanic can’t find the problem Check engine light on

Brakes seize up while driving and then cannot move the vehicle. This causes a dangerous situation while driving and then breaks lock up and cannot move car even though vehicle is on and then stopped for a stop light. Car must then be turned off and sit for about 30 minutes so it can unseize and when that happens, you can then resume driving and then check engine light comes on. Brake lights were staying on even when vehicle is shut completely off. ABS and ESC lights stay on consistently and never turn off. Vehicle brake switch was replaced at Carolina Hyundai of high point, NC. So break lights have been repaired. They had to order the stop switch lamp replacement for recall as it was never done and will be fixed in next week. 3 door handles fell off and cannot open the rear driver side door at all....

Engine leaking oil from the front cylinder bank’s valve cover or leaking from the valve cover’s gasket onto the alternator. A sufficient amount of oil could damage the alternator resulting in illumination of the charging system warning lamp and disablement of the charging system. If the vehicle is continually driven with a disabled charging system, the engine can shut off, increasing the risk of a crash.

Oil Leak on Alternator Engine leaking oil from the front cylinder bank’s valve cover or from the valve cover’s gasket onto the alternator. An unknown amount of oil damaged the alternator resulting in illumination of the charging system warning lamp and disablement of the charging system. If the vehicle is continually driven with a disabled charging system, the engine can shut off, increasing the risk of a crash.

I see that the manufacturer has an "Open Service Campaign" on their Sonata's shark fins. I've taken mine to the local dealership and they want a min. $700 to replace the shark fin. It just came off somewhere (a couple of years ago) and, now, my car has to be jumped off if I let it sit more than two days. I have had it inspected by the dealer and an individual garage. No one would tell me what was draining my battery. I am a senior citizen and fear I will get stranded on the road somewhere. The missing fin lets water into my car, soaking the carpets, etc. Finally, it was suggested that the car cover I keep on it touches the exposed fin components and that's what was draining my battery. It seems that the manufacturer was aware enough of this faulty part to want to prevent...

Valve cover gasket leaks and oil leaks on to the alternator which can cause the alternator to fail and the battery to not maintain a charge and the car can stall and then not start. This is the same exact problem problem that is in your recall on 2007-2012 Veracruz Recall number 20V705000 & 14V415000 And 2007-2009 Santa Fe vehicles have the same issue and Service Campaign 936 SB-10058931-4495 (TSB# 15-01-031).

We purchased this vehicle used 9/2022. A week later it began to jump upon accelerating and slowing down. We took it in and they said it was the power train control module and our warranty would not cover it. So it would cost us around $1600. We can’t afford that. We have only driven it a few times since. We were parked in front of a curb and the car accelerated us into a curb. Now, the ESC OFF, ABS, and engine light are illuminated. This is not a. It also wear and tear issues, as I’ve seen many others posting similar experiences. Our car is an ‘09 with almost 90,000 miles on it.

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...

TL* THE CONTACT OWNS A 2009 HYUNDAI SONATA. WHILE THE VEHICLE WAS STATIONARY, THE STEERING WHEEL AND THE IGNITION SWITCH SEIZED WITHOUT WARNING. THE VEHICLE WAS TOWED TO TYSINGER HYUNDAI IN HAMPTON, VIRGINIA TO BE REPAIRED, BUT THE DEALER COULD NOT FIND THE CAUSE OF THE FAILURE. IN ADDITION, THE DEALER STATED THAT A LOCKSMITH WOULD NEED TO UNLOCK THE IGNITION. THE MANUFACTURER WAS MADE AWARE OF THE ISSUE. THE FAILURE MILEAGE WAS APPROXIMATELY 80,248. UPDATED 10/18/17*LJ *TR

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

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...

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....

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...

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.

THE FRONT VALVE COVER GASKET LEAKED OIL DOWN TO MY ALTERNATOR, CAUSING IT TO MALFUNCTION AND MAKING MY TRANSMISSION SHIFT AWKWARDLY.

!) 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.

DURING THE LAST COUPLE OF WEEKS OF RAIN, WE HAVE HAD MULTIPLE OCCASIONS WHERE OUR VEHICLE HAS LOST POWER STEERING AND OUR BATTERY LIGHT GOES ON DURING LOW SPEED OPERATION. . THERE WAS NO DEEP PUDDLES, JUST NORMAL RAIN ON STREETS. IN SOME CASES, TOTAL STALL AND OTHERS ENGINE SCREECHES AND RESTARTS. WITHOUT WARNING. FILED COMPLAINT WITH HYUNDAI AMERICA. TOOK TO DEALER. WAS ADVISED THIS WAS A KNOWN PROBLEM FOR 2007-2009 HYUNDAI SONATAS. AND THERE WAS NO KNOWN FIX . HAD VEHICLE CHECKED. ADVISED ALL SPLASH GUARDS AND SHIELDS IN PLACE. COULD NOT BE DUPLICATED AT DEALERSHIP. ONE SERVICE REP AT DEALERSHIP ADVISED HIS WIFE HAS SAME PROBLEM. ALL BELTS AND PULLEYS AND TENSION SPRINGS OK. WE ARE VERY DISAPPOINTED IN THE RESPONSE WE HAVE RECEIVED AT HYUNDAI TO A "KNOWN " SAFETY PROBLEM. TO BE MORE SPECIFIC, FIVE(5) OCCASIONS HAVE OCCURRED. TOLD TO COME BACK WHEN IT RAINS. *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

PLEASE BE ADVISED THAT I PURCHASED SAID VEHICLE NEW AND AT AROUND 35000 MILES I STARTED TO NOTICE THAT WHEN I SLOWED DOWN AND CAME TO A STOP THE TRANSMISSION WOULD JERK ON THE DOWN SHIFT, WHICH IS NOT NORMAL. ON 01-19-2012 I BROUGHT MY CAR TO THE DEALER WHERE I PURCHASED FROM . I WAS INFORMED THAT THIS PROBLEM IS COMMON AND THAT ONCE MY COMPUTER IS RESET IT SHOULD GO AWAY, AND THERE IS A SERVICE BULLETIN ON THAT ISSUE. ON 03-19-2012 I WAS HAVING THE SAME ISSUE SO THE TRANSMISSION WAS REPLACED WITH FACTORY RECONDITIONED TRANSMISSION. NOW WITH 74000 MILE THE CAR IS BACK FOR THE 5 TH TIME FOR THE SAME TRANSMISSION PROBLEM. THE DEALER HAS MY CAR AND I HAVE NOT HEARD FROM THE DEALER OR HYUNDAI CORPORATION FOR TWO WEEKS. I BELIEVE THAT HYUNDAI CORPORATION KNEW THE PROBLEM EXISTED AND NEGLECTED TO FIX THE...

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...

I NOTICED A SHUDDERING AT 90,250 MILES, WHILE TRAVELING DURING THE WINTER AT AROUND 30-45 MPH, BUT WAS VERY INTERMITTENT, AND WOULD GO AWAY. THEN ON 10/9/2013 AT 102,515 MILES, FROM PARK, THE TRANSMISSION WOULD NOT ENGAGE INTO REVERSE OR DRIVE. I COULD HEAR THE TRANSMISSION SHIFT, BUT IT WAS NOT DISENGAGING FROM PARK. PER HYUNDAI SERVICE TECHNICIAN, THE TRANSMISSION WAS "JUNK" AND WOULD NEED TO BE REPLACED. I CONTACTED HYUNDAI CORPORATE, DURING WHICH TIME I WAS INFORMED THEY DIDN'T HAVE MY INFORMATION IN THEIR SYSTEM AND THAT IN FACT THERE WERE 2 RECALLS THAT THEY FAILED TO NOTIFY ME OF, AND WAS TOLD THAT IF I ALLOWED THE HYUNDAI SERVICE TO DO THE REPAIR RIGHT THEN, THAT I WOULD BE ELIGIBLE FOR THEIR POLICY REIMBURSEMENT. ONE OF THE RECALLS WAS AN ECM AND TCM SOFTWARE UPDATE IN WHICH SYMPTOMS WERE IMPROPER CLUTCHING AND DE-CLUTCHING OF GEARS WHEN ACCELERATING AND...

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.

SOME TIMES WHEN STARTING THE CAR WITH MY FOOT ON THE BRAKE THE RPMS GO UP TO ABOUT 1200 AND THEN DOWN TO 800 RPMS. WHEN MY FOOT IS REMOVED FROM THE BRAKE THE CAR WANTS TO ACCELERATE AND GO ON ITS OWN OFTEN. WHILE STOPED AT A STOP SIGN OR STOPED WITH MY FOOT ON THE BRAKE THE CAR WILL LURCH FORWARD WHEN RELEASED, SOME TIMES SPINNING THE TIRES. IT IS PROGRESSIVELY GETTING WORSE AFTER RETURNING FROM A 5000 MILE TRIP IN JUNE, 2013. THE CAR PURCHASED NEW AND HAS A AUTOMATIC TRANSMISSION WITH APROX. 65000 MILES TOTAL ON THE CAR. THIS IS A ACCIDENT WAITING TO HAPPEN AND SHOULD HAVE A RECALL. *TR

HEADLIGHTS DIM BUT DON'T AUTOMATICALLY SHUT OFF WHEN TURNING OFF THE CAR THUS DRAINING BATTERY LEAVING DEAD CAR. *TR

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
