I PLACED THE CAR IN PARK WHEN I GOT HOME FROM WORK WENT INSIDE MY HOUSE FOR A FEW MINUTES CAME OUTSIDE, WHEN I TURNED THE CAR ON AND TRIED TO TAKE IT OUT OF PARK IT WOULD NOT CHANGE GEARS. I TRIED IT FOR ALMOST 20MIN. I HAD TO TURN THE CAR OFF AND BACK ON A FEW TIMES FOR IT TO WORK. IT DOES IT ALMOST EVERYDAY. YESTERDAY 09/14/2011 I HAD TO DRIVE THE CAR AWAY FROM MY JOB DUE TO AN EMERGENCY AND IT WOULD NOT CHANGE GEARS. I TRIED AFTER 10MIN AND JUST LEFT THE CAR BEHIND AND HAD TO GET A RIDE FROM A COWORKER. IF THIS WAS A LIFE OR DEATH SITUATION I WOULD LIKELY NOT MAKE IT DUE TO THIS SAFETY ISSUE. THIS IS AN ONGOING PROBLEM. *KB

2011 SONATA SE DROPPED TO 4TH GEAR AT 70 MPH WITH LOUD BANG HAPPENED ONCE AND PUT IN SHOP COMPUTER HAD CODE TO REPLACE MODULE AND SOMETHING ELSE PARTS ON ORDER SHIFT SOLENOID *TT

FOR THE SECOND TIME, IN INTERSTATE HIGH SPEED TRAFFIC (70MPH) THE CAR WITHOUT WARNING DOWNSHIFTED. A THUNDEROUS CLUNK IS ACCOMPANIED BY THE CAR LURCHING AS IT DEACCELERATES THEN ALMOST IMMEDIATELY RESUMES SPEED. BUT INSTEAD OF THE ENGINE BEING AT 1800 RPM ITS CLOSER TO TWICE THAT. IN BOTH CASES THE DRIVER BEHIND ME THOUGHT THAT I BRAKED INTENTIONALLY AND NEARLY REAR ENDED ME. THE CAR IS THEN STUCK IN A LOWER GEAR AND IS DRIVEABLE WITH EXTREMELY POOR RESPONSE. I HAD IT TOWED ONCE AT THE DEALER'S REQUEST AND THE LAST TIME I WAS ABLE TO DRIVE IT TO A DIFFERENT NEARBY DEALER TO DEMONSTRATE THAT UNQUESTIONABLY THE CAR WAS STUCK IN ONE GEAR. IT IS AN AUTOMATIC. I'M SKEPTICAL THAT EITHER DEALER HAS ANY CLUE TO WHAT IS WRONG. I WON'T LET ANYONE IN THE FAMILY BESIDES ME DRIVE THE VEHICLE AS I'M AFRAID FOR THEIR SAFETY. IT HAS...

I HAVE A 2011 HYUNDAI SONATA SE, I HAVE BROUGHT IT TO THE DEALERSHIP 3 TIMES WITH THE SAME ISSUE. I KNOW THERE IS SOMETHING WRONG WITH THE TRANSMISSION AND THEY KEEP TELLING ME THAT THEY CANNOT DUPLICATE THE ISSUE AND SEND ME ON MY WAY. IT HAS HAPPENED NUMEROUS TIMES WHEN MY FIANCE OR I HAVE DRIVEN IT, NOW MY DAUGHTER (WHO JUST GOT HER LEARNER'S PERMIT) HAD IT HAPPEN TO HER. THE TRANNY SLIPS, IT MAKES A LOUD CLUNK WHEN TRYING TO GO IN REVERSE THEN THE CAR WILL NOT MOVE. I HAVE TO PUT THE CAR IN PARK, TURN IT OFF AND ON AGAIN THEN TRY AGAIN! OTHER TIMES I WILL BE DRIVING AND THE CAR REVS UP AND WONT MOVE THEN SLIPS INTO GEAR AND THEN CLUNKS BACK IN GEAR AGAIN CAUSING THE CAR TO BUCK. I DON'T KNOW WHAT HAS TO HAPPEN BEFORE THIS GETS...

I HAVE OWNED MY 2011 HYUNDAI SONATA FOR ONE YEAR. ON JULY 15, 2011, I WENT TO START THE CAR AND I COULD NOT DEPRESS THE BRAKE OR START THE CAR. THE ACC STUFF WOULD COME ON BUT NO IGNITION TO THE MOTOR. I TRIED AND TRIED TO START IT AND ENDED UP CALLING THE DEALERSHIP. I WAS TOLD TO "KICK" THE BRAKE PEDAL "HARD" SEVERAL TIMES; WHICH I DID. I FINALLY GOT IT STARTED AND DROVE IT TO THE DEALERSHIP. I WAS TOLD "BRAKE LIGHT SWITCH" REPLACED. LEFT THE DEALERSHIP AND DROVE TO MY OFFICE AND WHEN I WENT TO TRIED TO START THE CAR TO LEAVE THE CAR WOULD NOT START, BUT THIS TIME I HAD TO CALL ROADSIDE ASSISTANCE FOR THE CAR TO BE TOWED BACK TO DEALERSHIP. DEALERSHIP TOLD ME THEY REPLACED BRAKE LIGHT SWITCH AGAIN. NOW THE TRACTION CONTROL LIGHT COMES ON AND MY BRAKE...

I HAVE A 2011 HYUNDAI SONATA. I PURCHASED THE CAR IN AUGUST OF 2010. ABOUT A MONTH AFTER OWNING THE VEHICLE, THE ENGINE LIGHT CAME ON. WHEN I TOOK IT TO THE DEALER, THEY RECORDED THE CODE AND THEN SAID IT WAS THE AC. I WAS ASKED TO WAIT 15 SECONDS BEFORE TURNING THE AC ON AFTER STARTING CAR. SO I DID THAT. ABOUT A WEEK OR SO LATER, THE LIGHT COMES ON AGAIN. TAKE IT BACK TWICE AFTER THIS, THEY RECORD THE CODE AND THEN THE SWITCH IS REPLACED. I MAINTAIN MY CAR WITH ALL MAINTENANCE REQUESTED AND I DRIVE IT ON THE HIGHWAY. I HAD THE TIRE LIGHT COME ON A FEW MONTHS LATER - WAS TOLD IT WAS THE TEMPERATURE. THAT EVENTUALLY WENT OFF. NEXT WAS THE ENGINE LIGHT YET AGAIN. THIS TIME IT OCCURRED AFTER I TOOK THE CAR IN ON JUNE 17TH FOR AN OIL...

WHILE BACKING UP MY CAR AT A SLOW SPEED THE CAR ABRUPTLY STOPPED AS IF I HIT A BRICK WALL AND MADE A LOUD CRASHING SOUND. THE INDICATOR LETTERS IN THE DASHBOARD WERE BLANK AND THE SHIFTER GEARS LETTERS WERE NOT ILLUMINATED. CAR WAS ABLE TO GET INTO DRIVE AND WAS PARKED, I TURNED THE MOTOR OFF FOR A FEW MINUTES AND RESTARTED THE CAR. WAS ABLE TO GET IT HOME AND WILL CALL THE DEALER ASAP. *TT

BRAKE SWITCH FAILURE. LEFT CAR IMMOBILE. *TR

I STOPPED BY THE GAS STATION TO FILL UP AND TURNED OFF MY CAR. AFTER FILLING THE GAS TANK I ATTEMPTED TO START MY CAR AND WAS UNABLE TO GET THE CAR OUT OF "PARK." I TRIED MULTIPLE TIMES AND EVEN ASKED THE GAS ATTENDANT TO TRY AND THEY WERE UNABLE TO GET THE VEHICLE OUT OF PARK AS WELL. THIS LASTED FOR ABOUT 10 MINUTES BEFORE I WAS ABLE TO GET THE CAR OUT OF PARK AND PROCEED ON MY WAY. *TR

WHILE VERY COLD (IN THE MORNING DURING ALL WINTER) MY 2011 SONATA HAD SHIFTED FROM 3RD TO 4RT GEAR VERY FAST AND I HAD VERY HIGH RPMS. I WAS TOLD THAT I HAVE TO LEAVE MY CAR WITH THEM FOR COUPLE OF DAYS AND THEY DID NOT PROVIDE ME WITH THE LOANER. *TR

MY NEW HYUNDAI SONATA SE 2011 FAIL TO START OR TO TURN OFF ( I HAVE TO RESTART THE CAR IN ORDER TO DO IT). BESIDES THAT ONCE IN A WHILE THE TRANSMISSION INDICATOR DOES NOT SHOW ANY LETTER ON (R OR D OR P OR N).AGAIN,I HAVE TO RESTART THE CAR THEN IT GOES ON NORMALLY.WHEN DRIVING THE TRANSMISSION DOWNSHIFTS ABNORMALLY. *TR

THE TRANSMISSION IN MY 2011 HYUNDAI SONATA HAS FAILED TWICE. THERE IS A SOLENOID PROBLEM. FIRST TIME IT BLEW 2 SOLENOIDS @ 1,400 MILES, FELT LIKE I HIT A CINDER BLOCK THE 2ND TIME @ 2,700 MILES, THE TRANSMISSION BLEW OUT ON A MAJOR HIGHWAY. DEALER ADVISES MULTIPLE 2011 SONATA'S COMING IN WITH SOLENOID ISSUES. *TR

VIBRATION IN STEERING, GRINDING NOISE IN TRANSAXE, LOW TIRE PRESSURE (BY DEALER), REFUSAL TO PERFORM 3,750 MILE MAINTINCE SECDULE (DEALER REFUSED). *TR

HYUNDAI SONATA SE 2011, 630 MILES. WHILE TRAVELING ON AN OPEN STRETCH OF HIGHWAY AT A STEADY SPEED OF 70MPH, THERE WAS A SUDDEN LOUD 'THUMP' SOUND. THE ENTIRE VEHICLE JERKED VIOLENTLY WITH SUDDEN DECELERATION AS IF IT HIT A SOLID OBJECT. DRIVER DID NOT SEE ANY OBSTRUCTION OR IMPERFECTIONS ON THE ROAD PRIOR TO THE NOISE. DRIVER REALIZED THAT THE SPEED WAS ALMOST INSTANTLY REDUCED FROM 70MPH TO ~63MPH. RPMS WERE RACING UNUSUALLY HIGH, AROUND 3000 WHEN TYPICAL OPERATING RANGE IS 2000. DRIVER SHIFTED FROM AUTOMATIC 'DRIVE' GEAR TO SHIFTRONIC AND REALIZED THAT THE TRANSMISSION WAS STUCK IN 4. NEITHER THE MANUAL OR AUTOMATIC TRANSMISSION COULD CHANGE THE GEAR. DRIVER IMMEDIATELY TOOK VEHICLE TO DEALER. DEALER'S SERVICE DEPARTMENT ACKNOWLEDGED THAT THE TRANSMISSION WAS STUCK IN GEAR 4, BUT TECHNICIAN WAS ABLE TO RESET THE TRANSMISSION BY TURNING OFF THE ENGINE AND RESTARTING. BASED ON THE COMPUTERIZED ERROR CODES, DEALER...

WHEN DRIVING AT HIGHWAY SPEED THE CAR MADE A HUGE THUD, IT AUTOMATICALLY SHIFTED FROM 6TH TO 4TH GEAR AND REMAINED STUCK IN FOURTH GEAR UNTIL YOU TURN OFF THE CAR. TOOK CAR TO DEALER AND ENTIRE TRANSMISSION HAD TO BE REPLACED. *TR

I RECENTLY PURCHASED 2011 HYUNDAI SONATA 2.0T LIMITED. THE CAR HAS 1200+ MILES ON IT AND I HAVE IT FOR 4+ WEEKS. ONE MAJOR PROBLEM IS THE CAR IS PULLING TO THE LEFT AND THE STEERING WHEEL IS NOT AT ABSOLUTE CENTER. STEERING THIS CAR FEELS VERY HEAVY WHEN I TURN TO THE RIGHT AND VERY LIGHT WHEN I TURN TO THE LEFT. I AM NOT SURE WHAT IS GOING ON AND WHY THIS PROBLEM. CAN YOU PLEASE HELP? I HAVE SUBMITTED AN EMAIL TO HYUNDAI AND WILL BE TAKING THE CAR IN TO THE DEALER THIS WEEK TO HAVE IT CHECKED. VIN = [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

MY 2011 HYUNDAI SONATA TRANSMISSION WENT AFTER 2 MONTHS. THE RPMS WENT HAYWIRE AND IT SWITCH GEARS. I TOOK IT TO THE DEALERSHIP AND CHANGED THE TRANSMISSION. I HOPE THIS DOESN'T HAPPEN AGAIN. HOWEVER I 'M FINDING ALOT ON THE INTERNET IN REFERENCE TO THIS ISSUE. *LN

I OWN A 2011 HYUNDAI SONATA SE. 11000 MILES. ON DECEMBER 11,2010 WHILE ON I-16 IN SAVANNAH, GEORGIA, I WAS DRIVING MY SONATA AND IT FELT LIKE MY FRONT END BOTTOMED OUT. RPMS REVVED UP AND STAYED AT 5000 AND I WAS ONLY TRAVELING AT 65MPH. IT WAS LIKE I WAS STUCK IN 2ND GEAR. GEARS WOULDN'T SHIFT UP OR DOWN. THIS WENT ON FOR 10 MILES. WHEN I SLOWED AND ACCELERATED IT WAS VERY HESITANT. I STOPPED THE CAR AND TURNED THE IGNITION OFF FOR 20 MINUTES. WHEN I STARTED IT AGAIN, IT SHIFTED NORMALLY. NO OTHER OCCURRENCES SINCE THEN. *TR

I WAS DRIVING MY 2011 HYUNDAI SONATA SE. I WAS TRAVELING AT 45 MPH WHEN THE CAR SHUTTERED MADE A LOUD "CLUNKING" NOISE AND DOWNSHIFTED INTO 4TH GEAR. CAR WOULD THEN FAIL TO SHIFT INTO 5TH OR 6TH GEAR. WOULD NOT ACCELERATE TO HIGHWAY SPEEDS. I HAD THE CAR TOWED TO THE DEALER. THEY COULD NOT REPLICATE THE PROBLEM BUT DID FIND CODE DTC PO0748. THE DEALER REPLACED THE TRANSMISSION AT THE MANUFACTURES DIRECTION. THE VEHICLE WAS ONE MONTH OLD AND HAD 2121 MILES ON IT. *TR

WHILE DRIVING MY NEW 2011 HYUNDAI SONATA GLS SEDAN WITH 200 MILES ON THE ODOMETER, THE TRANSMISSION FAILED COMPLETELY WHEN A TRANSMISSION HOSE BLEW OFF RELEASING ALL THE OIL OUT OF THE TRANSMISSION. ONCE AT THE DEALERSHIP THEY SHOWED ME THAT HOSE CLAMP FOR THE HOSE HAD NEVER BEEN ATTACHED CORRECTLY AT THE FACTORY! THE CAR IS AT THE DEALERSHIP FOR REPAIRS. IT IS NOT KNOW AT THIS TIME IF THE TRANSMISSION HAS BEEN DAMAGED DUE TO THE LOSS OF OIL. WE WERE NOT HURT AND DIDN'T LOSE CONTROL OF THE CAR. THIS INCIDENT OCCURRED ON A FLAT PIECE OF HIGHWAY, SHOULD IT OCCURRED IN HILLY TERRAIN OR PASSING ANOTHER VEHICLE THE RESULTS COULD HAVE BEEN MUCH DIFFERENT SINCE THE CAR BECAME INOPERABLE. VERY DISAPPOINTING SINCE THE CAR HAD ONLY 200 MILES ON IT! *TR
