2009 Hyundai Sonata Complaint Log

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

Once the car gets slowed down and reaches 20 mph of speed by applying the brake or not. It gives a sudden jerk, which causes immediate reduction in speed.

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. Window electric system won’t let windows go up and down and had to make a latch pull string to open driver door. Passenger door will not open at all and no handle and is a dangerous situation. Break switch not being replaced would have cause an electrical fire and is a complete dangerous vehicle even after being inspected less than a week ago

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.

Brake Calipers are getting stuck often damaging the rotors and pads. This happens even for new calipers and rotors that won't last more than one year after replacement. The parts were original from manufacturer. The rear and front brakes were randomly getting stuck on one wheel after a period of using brakes. This put the vehicle in danger of getting fire from overheating rotors or increasing the risk of a crash because of an unusable brake system. This incident has repeated over time from 2017 till 2025 inducing big spendings for fixing brakes

The contact owned a 2009 Hyundai Sonata. The contact stated that while his daughter was driving at 45 MPH, the vehicle was turning the corner. It was unknown if any warning lights were illuminated. As a result, the vehicle was T-boned by a vehicle that was turning the corner, then crashed and the vehicle came to a stop at an unknown location. Most of the impact was received from the front passenger side. The other divers speed was unknown. None of the air bags deployed. The contact suffered injuries to the head and the lungs when she impacted the steering wheel. The contact was taken to the hospital by an ambulance. The contact's daughter was in a coma and had brain trauma and a punctured lung. A police report was filed. The vehicle was towed to a tow yard. The other vehicle owner was injured as well, the extent of his injuries was unknown. There was no property damage. The manufacturer was not made aware of the failure. The failure mileage was 140,000.

The contact owns a 2009 Hyundai Sonata. The contact stated while driving approximately 30 MPH, the steering wheel suddenly became stiff and failed to turn in either direction. No warning light was illuminated. The contact stated that an appointment was scheduled with the dealer to inspect the vehicle. The vehicle was not yet diagnosed or repaired. Upon further investigation, the contact related the failure to NHTSA Campaign Number: 10V426000 (Steering); however, the VIN was not included. The manufacturer was notified of the failure. The failure mileage was approximately 151,000.

Excessively cracked dashboard. The entire dash in my 2009 Hyundai Sonata is cracked and a replacement has been denied by Hyundai USA. A cracked dashboard could cause reduced structural integrity. The dashboard is a structural component designed to help absorb and distribute some of the forces in a collision. Cracks can compromise this ability to perform this function potentially increasing the force experienced by the occupants and the and other parts of the vehicle. It can also cause increased risk of debris and shrapnel. During a collision the cracked dashboard may break apart more easily causing sharp or jagged pieces to become projectiles inside of the cabin these fragments can pose a serious injury risk to occupants. It can also result in an impaired airbag deployment. Many vehicles have airbags in the dashboard a severely cracked dashboard could obstruct or improperly deploy airbags for example the air bag may not fully deploy reducing its effectiveness and the dashboard may puncture or otherwise interfere with the airbag as it inflates creating additional safety hazards. Cracks may expose sharp edges or materials under the dashboard which could harm occupants during a collision, especially in areas where passengers may come into contact with the dashboard. A cracked dashboard could also cause a compromised electrical system dashboards house numerous electrical systems, sensors and controls cracks could indicate underlying damage to these components. In a collision these systems may fail or behave unpredictably which could further reduce safety features. Cracked dashboards present a significant risk during a collision and should be addressed by the manufacturer promptly to ensure its customer safety.

5/18/24 in the afternoon, driving the car on freeway. the car lost power. AC stopped. Heat and check engine lights came on. Pulled car to shoulder. Driver’s window was foggy. Smoke coming from front. Exited the car. Flames seen underneath front of car and passenger compartment. Smoke worsened and within minutes 10 foot high flames engulfed the car. Fire department had to extinguish the flames. And California Highway Patrol blocked off several lanes. The vehicle totally was incinerated. I filed a police report number 240518LA2144. I do not have the report yet. It is not ready. It was filed with the California highway patrol.

Vehicle sat in driveway for one week while on cruise. The day of return the sonata caught on fire without any person touching the car for one week. Brother who’s house it was at was woken by neighbors at 7sm. Home had minor damage, but it could of been bad if it was in someone’s garage. Fire started in engine and console. Fire department could not find out a reason. Car was totaled. Had to rent a car to get home that was 2 hours away. Never had an issue with this vehicle in the 12 years I owned it.

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 complaints by voluntarily replacing problematic parts (thus the service campaign). And, there are a lot of videos on YouTube from DIY folks who've suffered through replacing the shark fins (many different models) themselves. It seems, however, the manufacturer only notified dealers with said "open service campaign," not the public, as in a proper Recall process. That way, they get to make more money off the public when the part falls off? Please advise how one might get the dealers to do the right thing. Thank you.

Passenger outside door handle fell off a couple years ago. Today the internal mechanism for the driver's side door broke so door will not open from the inside.

The sunroof detached from the vehicle at highway speed. The sunroof was not open or otherwise in operation when it detached. A mechanic concluded that the adhesive holding the glass to the sun roof assembly failed. The sunroof assembly was completely intact after the incident and did not appear to be damaged.

My door handles are breaking off. I was climbing in and out from my passenger seat..now my passenger and rear passenger door handles have broken off in the same day. I have no way in my vehicle now except through the window that I had to take off track to slide down to crawl in and out..im in a loss for words. This is humiliating.

P 215/60R16, TPMS IS ON , LOSS OF CONTROL OF VEHICLE FRONT RIGHT CONTROL ARM FAILURE ACTION # PE13007 NHTSA CODE: 13V354000

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.

The contact owns a 2009 Hyundai Sonata. The contact stated while driving at an undisclosed speed, the contact heard a loud grinding noise coming from the rear of the vehicle. The contact took the vehicle to a local dealer to be inspected. The contact later discovered that the dealer only did a visual inspection of the brake pads and rotors. The mechanic stated that there were metal shavings from the brake pads and that the contact should wash the wheels to clear the metal shavings. The wheels were washed as instructed; however, the failure persisted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 181,000.

The problem as reported by so many others that the rear brake system has an inherent failure in the caliper/rotor/brake pads. I have vested nearly $2500.00 on the three for mentioned parts and labor over last 4 years. Between Midas and now a private mechanic have tried better lube on slide pins but the problem still persists. A little research states that the caliper piston doesn't retract from the rotors and in turn heating up the brake components to the point of failure. Some Law firms have stated the problem is a production flaw my problem with a system with this failure rate isn't recognized by the Hyundia. Calipers should simply last 80 to a 100 thousand miles under most driving conditions. Looking forward to your response. Kerry yakel

None of my lights on my dash has changed. Areas affected: Service Brakes, Hydraulics, and exterior lighting, Failure to illuminate the stop lamps during braking or inability to engaged the cruise control could increase the risk of a crash. As mentioned in the recall from 4/1/13. 2nd recall For Suspension: control arm separation May suddenly changed the rear wheel alignment affecting the handling of the car increasing the risk of a crash. Another main common issue is The rusted out subframe, lower control arms, cam bolts, bushings, control arm, subframe, and sway bar. This is causing me to drive unstable and hold the steering wheel forcefully in order to remain straight.

Dash pad directly above the passenger side airbag has cracked with an approximately 12 inch vertical long crack

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.

The contact owns a 2009 Hyundai Sonata. The contact stated while attempting to open the front driver’s side door, the outside door handle detached from the vehicle. The contact also stated that all four door handles had detached from the vehicle. The contact called the local dealer and made them aware of the failure. The vehicle was not repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 180,000.

STEERING WHEEL WOULD LOCKS UP FOR A SECOND OR 2 WHILE MAKING A RIGHT TURN AROUND 15MPH THEN I WOULD HAVE TO LET MY FOOT OF THE GAS JUST TO GET THE STEERING WHEEL BACK TO NORMAL. HAD THIS HAPPEN TOO MANY TIMES ALREADY. TRIED FIXING THE PROBLEM BY HAVING A MECHANIC SHOP CHANGE THE AXLES AND BUYING A NEW RACK N PINION AND TIRES AND GETTING A ALIMENT DONE IN MARCH OF THIS YEAR. STEERING IS STILL GETS STIFF WHILE MAKING TURNS EVEN WITH ALL THE NEW PARTS ON THE CAR NOW

I HAD TAKEN THE VEHICLE FOR ALIGNMENT. THEY SAID BOLTS RELATED TO REAR TIE RODS WERE RUSTED AND THEY COULD NOT DO IT. I TOOK IT TO ANOTHER MECHANIC FOR INSPECTION AND POSSIBLE REPAIR. HE SAID THE SAME. IN ADDITION HE ALSO SAID THAT THE STRUTS ARE LEAKING. I LOOKED INTO THE HISTORY OF MY VEHICLE, AS I BOUGHT IT USED 2 YEARS AGO. I FOUND THAT THE VEHICLE HAD BEEN RECALLED IN 2013 FOR SUSPENSION RELATED ISSUES. AND SOME 239000 VEHICLES WERE AFFECTED. I BELIEVE ITS THE SAME ISSUE WHICH HAS RESURFACED AGAIN. THE VEHICLE IS PERFECTLY FINE OTHERWISE. BY THE WAY I HAVE A SALVAGE TITLE OF THE VEHICLE ON MY NAME IF THAT IS IMPORTANT INFORMATION.

TL* THE CONTACT OWNS A 2009 HYUNDAI SONATA. THE CONTACT STATED THAT WHILE HIS SON WAS ATTEMPTING TO PARK AT THE CAR WASH, THE VEHICLE INADVERTENTLY ACCELERATED CAUSING THE VEHICLE TO JUMP THE PARKING BARRIER HITTING THE VACUUM MACHINE. NO INJURIES WERE SUSTAINED HOWEVER THE VACUUM MACHINE WAS DAMAGED ALONG WITH THE FRONT BUMPER WAS CRACKED AND SCRATCHED. THE MANUFACTURER WAS NOTIFIED AND THE VEHICLE WAS INSPECTED AT RICK CASE (180 SATELLITE BLVD DULUTH GA, 30096) WHERE NO FAILURE WAS DETERMINED. THE FAILURE MILEAGE WAS 142,000.

TL* THE CONTACT OWNS A 2009 HYUNDAI SONATA. THE CONTACT STATED THAT WHILE HIS SON WAS DRIVING 70 MPH, THE VEHICLE STALLED WITH AN ABNORMAL KNOCKING SOUND COMING FROM THE ENGINE. HIS SON ALSO STATED THAT THE CHECK ENGINE WARNING LIGHT WAS ILLUMINATED. THE CONTACT'S SON COASTED THE VEHICLE INTO A PARKING LOT WHERE THE VEHICLE REMAINED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE CONTACT WAS INFORMED THAT THE VIN WAS NOT UNDER RECALL. A CASE NUMBER WAS PROVIDED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 180,000.

INSTALLED FOUR (4) BRAND NEW GENERAL ALTIMAX RT43 TIRES. NEW TIRES HAD 3877 MILES ON THEM WHEN THE DRIVER'S SIDE REAR TIRE SUFFERED A SUDDEN, RAPID LOSS OF AIR TRAVELING ON A MAINTAINED COUNTY HIGHWAY AT 55 TO 60 MILES PER HOUR. THE TIRE WAS EXAMINED AT THE DEALERSHIP AND DETERMINED TO HAVE A SLICE OR CUT IN THE SIDEWALL RESULTING IN EXTREME, RAPID TIRE FAILURE. THERE WAS NEITHER NO POTHOLE OR FOREIGN OBJECT TRAVERSED PRIOR TO THE EXTREME, SUDDEN TIRE FAILURE. HAVING BEEN A CERTIFIED EMERGENCY VEHICLE OPERATIONS INSTRUCTOR, AND HAVING SERVED AS A COMMITTEE MEMBER FOR THE STATE OF WISCONSIN, DEPARTMENT OF JUSTICE AS AN ADVISOR FOR EMERGENCY VEHICLE OPERATIONS, I AM MOST CONFIDENT IN MY OBSERVATION AND ASSESSMENT. THE TIRE SIMPLY FAILED FOR NO IDENTIFIABLE, RATIONAL REASON.

THE IGNITION LOCKED, THE KEY WAS UNABLE TO TURN OVER. THANKFULLY, I WAS PARKED IN A BUSINESS ESTABLISHMENTS PARKING LOT.

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...

I WAS DRIVING ON THE HIGHWAY WHEN I HEARD SOMETHING POP INSIDE THE HOOD FOLLOWED BY A LOUD KNOCKING SOUND. I LOST ACCELERATION POWER AND I HAD ALMOST GOTTEN HIT BY SEMI WHILE ROLLING TO SIDE OF THE ROAD. TAKEN IT TO MECHANIC SHOP SAID THAT'S MY ENGINE ROD BEARING WAS BROKEN. SAD SINCE THIS IS MY FIRST VEHICLE.

COMPLETE BREAK SYSTEM AS BEEN DONE AS WELL AS TIRES WITH ROTATIONS, HAVING TO REPLACE BRAKES AND ROTARS OFTEN. CONTINUES TO PULL HARD TO RIGHT WHILE DRIVING AND IS FAR FROM A SMOOTH RIDE. WHEN BREAKING THE CAR FEELS TO PULL FORWARD. THE EMERGENCY BREAK DOES NOT WORK AT ALL. THIS FEELS LIKE A NEVER ENDING ISSUE. THE CAR SEEMS TO SIT LOW ON ONE SIDE, HAVE TO TAKE IT TO GET LOOKED AT.

AS I TRIED TO OPEN MY PASSENGER FRONT SIDE DOOR THIS MORNING I PULLED THE HANDLE OFF. THE PORTION OF THE HANDLE THAT CONNECTS INTO THE LATCH MECHANISM HAD SNAPPED OFF IN THE DOOR. I WOULD JUST TAKE IT IN AND GET IT FIXED, BUT THIS IS THE THIRD TIME I HAVE HAD THIS EXACT PROBLEM, HAVING LOST THE PASSENGER REAR HANDLE EARLIER THIS SUMMER AND THE DRIVER'S FRONT ABOUT A YEAR AND A HALF AGO. I CAN ONLY CONCLUDE THERE MUST BE A DISTINCT DEFECT WITH THE CONSTRUCTION ON THE DOORS OF THIS MODEL, AND SEARCHING AROUND THE INTERNET I'VE FOUND A HANDFUL OF OTHER PEOPLE WHO HAVE HAD THE SAME ISSUE WITH THEIR SONATAS.

WAS DRIVING DOWN INTERSTATE ENGINE LIGHT CAME ON CAR CUT OFF TOOK ALL I HAD TO COAST TO THE SHOULDER HAD TO CALL TOW TRUCK TO COME GET ME TOOK TO A GARAGE AND THEY INFORMED ME I NEEDED A NEW MOTOR.

WAS DRIVING AND OUT OF NO WHERE THE ENGINE LIGHT CAME ON AND ALL POWER WAS LOST. COULD HARDLY CONTROL THE STEERING. PULLED OVER AND WAITED A MOMENT AND STARTED THE CAR AGAIN. AFTER TWO MINUTES THE SAME PROBLEM HAPPENED. MECHANIC SAID TO BRING IT STRAIGHT TO HYUNDAI AND DEMAND A NEW ENGINE. THIS SHOULD BE A RECALL. VERY DANGEROUS TO HAPPEN WHILE DRIVING. *TR

I WAS EXITING THE FREEWAY AND MY CAR ENGINE JUST DIED. I COULDN'T STOP AND RAN THROUGH THE INTERSECTION. MY CAR WOULDN'T START AFTER THAT. I HAD IT TOWED TO A GARAGE WHERE THEY TOLD ME THE ENGINE HAD SEIZED UP. *TR

TL* THE CONTACT OWNS A 2009 HYUNDAI SONATA. THE CONTACT STATED THAT THE DRIVER'S SIDE FRONT DOOR WAS UNABLE TO BE OPENED FROM INSIDE THE VEHICLE. THE CONTACTED ROLLED THE WINDOW DOWN AND UNLOCKED THE DOOR USING THE OUTSIDE DOOR HANDLE. THE VEHICLE WAS TAKEN TO KEY HYUNDAI LOCATED AT (4660-100 SOUTHSIDE BOULEVARD, JACKSONVILLE, FL 32216 (904) 642-6060) WHERE THE TECHNICIAN INSPECTED THE DOOR AND DETERMINED THAT THE DOOR HANDLE CLIP FRACTURED AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 163,881.

PLEASE, I WENT TO ONE OF THE VISION HYUNDAI OUTLETS TO RECTIFY SOME RECALLS ON MY HYUNDAI 2009 SONATE. I WAS ALSO INFORMED BY THE MECHANIC THAT MY SUBFRAME HAS HOLES AND ADDED THAT IT CALLS FOR CONCERN AS A SAFETY ISSUE. PLEASE, I DO NOT HAVE THE $800 HE SAID IT WOULD COST. I SEE THAT SOMEOTHER PERSONS HAD COMPLAINED IN THE PAST AND MADE A CLEAR STRONG STANDING TO HYUNDAI CONSUMER AFFAIRS THAT IT IS A SAFETY ISSUE AND HAD THEIR VEHICLES REPAIRED AT NO COST TO THE OWNERS. BEARING IN MIND THAT A SUBFRAME ON A CAR SHOULD NOT BE RUSTING OUT, I NEED YOUR INPUT TO HAVE THIS ISSUED RESOLVED.

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.

THE CAR DRIVES NORMALLY UNTIL YOU PRESS ON THE BRAKES AFTER GOING HIGH SPEEDS IT JERKS. AT STOPS IF THE CAR ISN'T IN NEUTRAL THE ENGINE STUTTERS WE'VE REPLACED THE CAM SHAFT SENSOR 3 TIMES NOW AND THAT'S THE CODE THAT COMES UP EVERYTIME THE CHECK ENGINE LIGHT COMES ON AFTER THE JERKING. WE ALSO REPLACED THE SPARK PLUGS AND COILS HOPING IT WOULD HELP THE SHAKING AT STOPS AND IT DIDN'T.

TL* THE CONTACT OWNS A 2009 HYUNDAI SONATA. WHILE REVERSING, THE VEHICLE VIOLENTLY ACCELERATED AND STRUCK A LIGHT POLE. THE CONTACT SHIFTED INTO DRIVE AND THE VEHICLE ACCELERATED AGAIN. THE CONTACT MENTIONED THAT THE TIRES WERE SPINNING. AFTER SEVERAL ATTEMPTS, THE CONTACT SHIFTED INTO PARK AND THE VEHICLE STOPPED. THE VEHICLE WAS RESTARTED AND DROVE NORMALLY. THERE WERE NO INJURIES. THE VEHICLE WAS NOT TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND OPENED A CASE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 180,000. THE VIN WAS UNKNOWN.

AIRBAG LIGHT WILL NOT TURN OFF. I HAVE TAKEN THE CAR TO TWO DEALERSHIPS AND THEY HAVE NOT BEEN ABLE TO FIX THE PROBLEM. THE OCS IS DEFECTIVE. I HAVE HAD THE CAR FOR 10 YEARS AND NO ONE EVER SITS IN THE PASSENGER SEAT. I DO PUT GROCERIES ON THE SEAT AT TIMES. I BELIEVE THE PROBLEM IS THE SAME AS THE TSB CAMPAIGN THAT WAS PUT OUT FOR 2006 -2008 SONATA. THE CAMPAIGN NUMBER IS 083. HOW CAN I FIND OUT IF MY 2009 SONATA WAS MANUFACTURED IN 2008? WHEN THE VEHICLE WAS RETURNED FROM THE FIRST DEALER THE SEATBELT LIGHT WAS FLASHING.
