2011 Hyundai Sonata Electrical System

TL* THE CONTACT OWNS A 2011 HYUNDAI SONATA. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 20 MPH, SHE APPLIED PRESSURE TO THE HORN BUT IT WOULD NOT SOUND. THE VEHICLE WAS NOT TAKEN TO THE DEALER FOR DIAGNOSTICS OR REPAIR. THE APPROXIMATE FAILURE MILEAGE WAS 3,200.

THE HORN SUPPLIED WITH THIS VEHICLE IS SO LOW IT CAN NOT BE HEARD BY OTHER DRIVERS. *KB

MY 2011 HYUNDAI SONATA HYBRID "CHECK CHARGING SYSTEM" LAMP ILLUMINATED WITH CHIME ALARM ACTIVATION WHILE DRIVING, CAUSING LOSS OF ENGINE POWER. HYBRID BATTERY CHARGE LEVEL WAS AT 1/2, WHICH IS WHERE IT NORMALLY IS. I PRESSED ON GAS PEDAL AND GOT NO RESPONSE, AND VEHICLE CAME TO A STOP AS IF I APPLIED THE PARKING BRAKE. I PLACED VEHICLE IN PARK, SHUT OFF ENGINE AND RE-STARTED IT AND IT RAN NORMALLY. THIS IS THE SECOND TIME IT HAPPENED IN THE PAST 4 WEEKS OR SO. ON A HYUNDAI FORUM WEBSITE, THERE IS AT LEAST 1 OTHER CUSTOMER WHICH HAS HAD THE SAME PROBLEM WITH THEIR HYBRID AS MYSELF. IT IS VERY DANGEROUS SITUATION IF YOU ARE ON THE HIGHWAY AND YOU ARE FORCED TO STOP WHILE IN FLOW OF TRAFFIC. *TT

MY 2011 SONATA HAS FAILED TO START 3 TIMES THIS PAST MONTH. THE BRAKE WILL NOT DEPRESS AND IT APPEARS THAT IT DOESN'T RECOGNIZE THAT I HAVE THE KEY. IT HAS A PUSH BUTTON START AND THE KEY DOES NOT GO IN THE IGNITION. AFTER A FEW HOURS IT STARTS. I HAVE BEEN STRANDED IN THE DARK AND THIS MADE IT A SAFETY ISSUE ON A PERSONAL BASIS. *TR

THE "CHECK CHARGING SYSTEM" LIGHT APPEARED THE 1ST WEEK THAT WE HAD THIS NEW( HYUNDAI 2011 SONATA HYBRID) CAR WHILE MY WIFE WAS DRIVING THE CAR. SHE LOST POWER TO THE VEHICLE AND HAD TO STOP AND RESTART. I RETURNED IT TO THE DEALER THAT AFTERNOON AND THEY STATED THAT THE BATTERY TERMINAL WAS LOOSE AND NEEDED ADJUSTMENT. THE CAR HAD ABOUT 200+ MILES ON IT. TODAY, NOVEMBER 6, 2011, I WAS WITH MY WIFE AND SHE WAS DRIVING AND THE " CHECK CHARGING SYSTEM' LIGHT AGAIN CAME ON WITH AN AUDIBLE ALARM. ( ABOUT 400+ MILES). WE LOST POWER AT A TRAFFIC LIGHT AND HAD TO STOP AND THE CAR WAS DIFFICULT TO RESTART. AFTER CHECKING THE HYUNDAI FORUMS, THIS APPEARS TO BE A FREQUENT OCCURRENCE WITH NUMEROUS DRIVERS AROUND THE COUNTRY. MANY REGISTERED FORUM USERS ARE CONCERNED THAT THIS IS A MAJOR SAFETY ISSUE AND NEEDS TO BE ADDRESSED IMMEDIATELY. I AM TAKING THE CAR BACK TO THE DEALER ON MONDAY MORNING AND WANTED TO HAVE THIS DOCUMENTED. MY WIFE DOES NOT FEEL SAFE IN THIS VEHICLE ( AND NEITHER DO I AT THIS TIME). *TR

2011 HYUNDAI SONATA FAILED TO START. I TRIED SEVERAL TIMES AND THE KEY LIGHT WAS LIT ON THE DASH PANEL. TRIED SEVERAL TIMES AND PRESS BRAKE PEDAL WAS SCREAMING AT ME AS I PRESSED THE DARN THING. TRIED THE KEY BOB IN THE SLOT IN THE STORAGE AREA AND SAME RESULT. GOT OUT OF THE CAR AND CLOSED AND LOCKED THE DOORS. BACK IN AND TRIED AGAIN WITH THE SAME RESULTS. CALLED MY NEXT CUSTOMER AND TOLD THEM I WOULD BE LATE AS MY CAR WOULD NOT START. FINALLY AFTER 20 MINUTES I WAS ABLE TO GET THE CAR STARTED WITH THE BOB IN THE STORAGE AREA. WENT STRAIGHT TO THE DEALER -THEY HAVE NEVER HEARD OF THIS HAPPENING. *TR

A FEW TIMES I HAVE NEARLY HAD ACCIDENTS, INVOLVING BOTH CARS AND PEOPLE BECAUSE THE HORN CANNOT BE HEARD! I THINK A HORN IS A SAFETY DEVICE, TO WARN OTHERS, BUT THIS ONE CANNOT. IT SOUNDS LIKE IT IS FROM A MOTOR SCOOTER. UNFORTUNATELY, SOMEONE WILL PROBABLY END UP BEING HIT, INJURED OR EVEN KILLED BEFORE SOMETHING IS DONE. I HAVE HEARD THAT HYUNDAI, IN EFFECT, ADMITTED THE PROBLEM BY RE-DESIGNING THE HORN ON LATER 2011 MODEL YEAR CARS. ALL CARS SHOULD GET THE NEW HORN. THIS TYPE OF INCIDENT HAPPENS EVERYTIME SOMEONE PULLS OR WALKS OUT IN FRONT OF ME AT THE LAST SECOND, AND I AM UNABLE TO PROPERLY WARN THEM WITH THE HORN. *TR

THE HORN ON MY 2011 HYUNDAI SONATA IS NOT LOUD AT ALL. I HONK AT PEOPLE AND THEY HAVE NO IDEA I AM HONKING AT THEM. ITS VERY QUIET AND HIGH PITCH. THIS COULD CAUSE A SERIOUS ACCIDENT IF THE HORN WAS SERIOUSLY NEEDED ON A HIGHWAY OR SOMETHING. *TR

HAVE A 2011 HYUNDAI SONATA LIMITED AND YESTERDAY WHEN ATTEMPTING TO START THE CAR THE PUSH BUTTON START FAILED. I HAD MY FOOT ON THE BRAKE AND HIT THE BUTTON AS I ALWAYS DO AND NOTHING. THE DASHBOARD KEPT READING "PRESS ON BRAKE PEDAL AND PUSH BUTTON TO START" I REPEATEDLY TRIED OVER AND OVER. AFTER 15-20 FAILED ATTEMPTS I WAITED A FEW MINUTES AS I LOOKED UP THE ROADSIDE ASSISTANCE NUMBER. AFTER FINDING THE NUMBER I TRIED "ONE LAST TIME" AND THE LUCKILY THE CAR STARTED. I DROVE HOME PARKED IT AND THIS MORNING WENT OUT AND THE CAR STARTS. I HAVE SCHEDULED AN APPOINTMENT AT THE DEALERSHIP LATER IN THE WEEK AND HOPE THEY GET THIS FIXED. FROM WHAT I READ ONLINE A LOT OF PEOPLE ARE HAVING THE SAME PROBLEM AND THE "ATTEMPTED DEALER FIXES" HAVE NOT COMPLETELY SOLVED THE PROBLEM. HYUNDAI NEEDS TO FIGURE IT OUT AND MAKE THIS RIGHT. HOW CAN ANYONE FEEL COMFORTABLE DRIVING THIS CAR WITH THE THOUGHT THEY CAN BE STRANDED AT ANYTIME. *TR

TL*THE DRIVER OWNS A 2011 HYUNDAI SONATA. THE VEHICLE WAS EQUIPPED WITH A KEY FOB IN WHICH THE VEHICLE WAS SUPPOSED TO SHUT OFF ONCE THE KEY FOB WAS WITHIN A SPECIFIED DISTANCE AWAY FROM THE VEHICLE. THE VEHICLE WOULD INTERMITTENTLY REMAIN IN THE ON POSITION WHEN THE KEY FOB WAS BEYOND THE ALLOTTED DISTANCE FROM THE VEHICLE WHICH FORCED THE DRIVER TO MANUALLY TURN THE VEHICLE OFF. HE VEHICLE WAS NOT TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 5,200 AND THE CURRENT MILEAGE WAS UNKNOWN.

FOR THE THIRD TIME I HAVE GOTTEN IN MY 2011 HYUNDAI SONATA SE AND IT WILL NOT START (PUSH TO START). THE SCREEN WILL EITHER SAY THE KEY IS NOT IN THE VEHICLE OR IT WILL SAY PRESS BRAKE PEDAL TO START (THE KEY IS CERTAINLY IN THE VEHICLE, HOW ELSE DID I GET IN WITH IT LOCKED). AFTER REPEATEDLY GETTING IN AND OUT OF THE CAR, LOCKING AND UNLOCKING PRESSING THE BREAK PADS, TRYING EVERYTHING AND THEN SOME FOR ABOUT A HALF HOUR THE VEHICLE STILL WILL NOT START. THIS IS THE FOURTH HYUNDAI I HAVE PURCHASED, SECOND BRAND NEW AND I HAVE NEVER HAD PROBLEMS LIKE THIS BEFORE BUT THIS IS RIDICULOUS. I'VE TAKEN IT TO THE DEALER AND THEY SAY THEY HAVE NEVER HEARD OF THIS HAPPENING EVEN THOUGH I HAVE FOUND NUMEROUS COMPLAINTS FOR IT ONLINE (WHAT SOURCES ARE THEY USING, GOOGLE TURNS UP PLENTY OF INFORMATION). THIS IS THE THIRD TIME I HAVE BEEN STRANDED IN A DARK, POTENTIALLY DANGEROUS AREA UNABLE TO START MY BRAND NEW CAR THAT HAS ALREADY HAD A RECALL. I EXPECT MORE THAN THIS.I WILL DROP IT OFF AT THE DEALERSHIP AGAIN AND AFTER THAT I AM GOING TO INVOKE THE LEMON LAW. ONE RECALL IS BAD ENOUGH I WOULD AT LEAST LIKE TO BE ABLE TO START MY VEHICLE. THE BATTERY IS FINE BOTH IN THE CAR AND THE REMOTE. AT 8,000 I SHOULD NOT HAVE ANY ISSUES! *TR

I INITIALLY UNLOCK THE VEHICLE BY EITHER DEPRESSING THE UNLOCK BUTTON ON THE KEY FOB OR PRESSING THE UNLOCK BUTTON ON THE OUTSIDE DOOR HANDLE. ONCE UNLOCKED, I ENTERED THE VEHICLE AND ATTACH THE SEAT BELT. I PLACE THE KEY FOB ON THE DASHBOARD, DEPRESS THE BRAKE PEDAL AND PRESS THE ENGINE START BUTTON. THE ELECTRICAL SYSTEM WILL CYCLE THROUGH ACC AND ON MODE BUT THE CAR WILL NOT START. A CHECK OF THE BATTERY SYSTEM SHOW THAT THE CAR BATTERY IS AT FULL POWER. THIS PROBLEM OCCURS INTERMITTENTLY. THE ONLY RELIABLE SOLUTION FOR STARTING THE CAR IS TO DEPRESS THE BRAKE PEDAL AND DEPRESS THE ENGINE START BUTTON FOR A MINIMUM OF 10 SECONDS. I'VE PLACED THE KEY FOB IN SEVERAL LOCATIONS IN THE CAR (DASHBOARD, CUP HOLDER, SMART KEY HOLDER) WITH NO REPEATABLE SUCCESS. AFTER A VISIT TO A DEALERSHIP, THEY CANNOT FIND A PROBLEM. HOWEVER, A SEARCH ON THE INTERNET SHOWS SEVERAL THERE OWNERS EXPERIENCING THE SAME PROBLEM. *TR

MY CAR WAS WARMING UP IN THE DRIVEWAY. IT WAS RUNNING FOR ABOUT 5 MINUTES. I WENT OUTSIDE AND IT WAS ON FIRE. THE FLAMES WERE COMING FROM UNDERNEATH THE HOOD. THERE IS ONLY ONE RECALL FOR THIS AND IT WAS MECHANICAL RELATED TO THE STEEERING COLUMN. THE FIRE WAS A DIFINITIVE SMELL OF ELECTRICAL BURNING. THE CAR WAS A TOTAL LOSS. *TR

TL*THE CONTACT OWNS A 2011 HYUNDAI SONATA. THE CONTACT STATED THAT THE HORN WAS NOT LOUD. THE CONTACT STATED THAT THE MANUFACTURER DID NOT INSTALL A DUAL HORN WHICH COULD CAUSE AN ACCIDENT BEAUSE ANOTHER DRIVE MIGHT NOT HEAR THE HORN. THE CURRENT AND FAILURE MILEAGES WERE 700.

TL*THE CONTACT OWNS A 2011 HYUNDAI SONATA. WHILE DRIVING APPROXIMATELY 20 MPH, THE CONTACT ATTEMPTED TO ENGAGE THE HORN BUT IT COULD BARELY BE HEARD. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHERE THE CONTACT WAS TOLD THAT THE HORN WAS DESIGNED IN THAT MANNER. THE VEHICLE HAD NOT BEEN REPAIRED. THE FAILURE MILEAGE WAS 52 AND THE CURRENT MILEAGE WAS 1,242.

THE HORN IN A 2011 HYUNDAI SONATA IS VERY WEAK. ON A HIGHWAY WITH ALL THE ROAD NOISE CARS CANNOT HEAR THE HORN. WHEN THE HORN IS USED IT SOUNDS LIKE IT IS IN THE DISTANCE AND NOT WARNING THE CAR NEAR YOU. THE HORN SHOULD BE REPLACED WITH A LOUDER AUDIBLE HORN. *TR

I HAVE A 2011 HYUNDAI SONATA. THE HORN IS A REAL SAFETY HAZARD. YOU CAN HARDLY HEAR IT INSIDE THE CAR, AND IN TRAFFIC, OTHER CARS CAN NOT HEAR IT WITH ALL THE ROAD NOISE.

MY 2011 HYUNDAI SONATA HAS BEEN FAILING TO START OVER THE PAST 2 DAYS. THE PROBLEM IS INCONSISTENT, IT AT TIMES TAKES 5 MINUTES TO START AND AT OTHERS IT TAKES 20 MINUTES BEFORE THE CAR TURNS ON. AFTER SEVERAL ATTEMPTS TO START THE CAR, A DISPLAY MESSAGE APPEARS NEAR THE ODOMETER STATING THAT YOU MUST PRESS BRAKE TO TURN VEHICLE ON (THIS MODEL USES A PUSH START BUTTON). THE PROBLEM IS THAT THE BRAKE PEDAL LOCKS IN PLACE AND CANNOT BE PRESSED DOWN. *TR

TL*THE CONTACT LEASED A 2011 HYUNDAI SONATA. THE CONTACT STATED THAT AFTER TURNING THE MOTOR OFF, THE KEY WAS NOT ABLE TO BE EXTRACTED FROM THE IGNITION. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALERSHIP WHERE THE DEALER STATED THAT HE HAD TO MANEUVER THE KEY A CERTAIN WAY. THE VEHICLE HAD NOT BEEN REPAIRED AT THE TIME OF THE COMPLAINT. THE CONTACT CALLED THE MANUFACTURER AND FILED A COMPLAINT. THE CURRENT MILEAGE WAS APPROXIMATELY 740. THE FAILURE MILEAGE WAS APPROXIMATELY 30.

I BACK UP A PREVIOUS COMPLAINT THAT THE HORN ON THE 2011 HYUNDAI SONATA IS COMPLETELY WORTHLESS AND A SAFETY HAZARD. IT IS SO QUIET THAT IT IS USELESS AS A WARNING TO PEDESTRIANS OR OTHER MOTORISTS SHOULD THE NEED ARISE. IT HAS TO BE REPLACED WITH A "NORMAL" LOUD HORN. *TR

TO THE PERSON WHO HAD STARTING PROBLEMS WITH THE 2011, I AGREE. MINE HAS BEEN IN THE DEALER'S SHOP OVER EIGHT TIMES WITH THE SAME "INTERMITTENT" PROBLEMS THAT THEY CAN'T SOLVE. WON'T START, OR DELAYS STARTING WITH THE NEW ELECTRONIC START BUTTON. LEFT ME IN A DANGEROUS SITUATION IN A PARKING LOT 30 MILES FROM HOME. *TR

2011 HYUNDAI SONATA HORN IS SO WEAK AS TO BE INAUDIBLE AT HIGHWAY SPEEDS. IT NEEDS TO BE UPGRADED TO A DUAL TONE IMMEDIATELY BEFORE SOMEONE GETS HURT FROM NOT HEARING THE HORN. ON A CAR OF THIS CALIBER, THERE IS NO EXCUSE. I HOPE I GET A NOTICE TO BRING MINE 2 DAY OLD CAR WITH 370 MILES IN FOR A REPLACEMENT OF THE HORN. LANE CHANGE GOING HOME FROM DEALER CAUSED ME TO NOTICE THIS. SCARED BOTH MYSELF AND THE GUY TRYING TO SWERVE INTO MY LANE. *TR

I WAS DRIVING MY VEHICLE DOWN A FOUR LANE ROAD AND ANOTHER VEHICLE DRIVING PARALLEL TO ME STARTED CREEPING INTO MY LANE. I APPLIED THE HORN OF MY VEHICLE BUT THE OTHER DRIVER FAILED TO HEAR ME. I HAD TO SWERVE OFF THE ROAD TO AVOID THEM. I HAVE NOTICED THAT THE HORN IN MY CAR IS VERY WEAK COMPARED TO PREVIOUS CARS I OWN, AND AM CONCERNED ABOUT OTHER PEOPLE HEARING IT. *TR

2011 HYUNDAI SONATA SE 16 DAYS OLD, 2018 MILES: CAR HAS AN "INTERMITTENT STARTING PROBLEM". IT HAS LEFT MY WIFE STRANDED AT WORK 3 TIMES, TWO OF THOSE TIMES IN A DESERTED PARKING LOT AFTER HOURS, ONCE AT THE DEALER WHEN I WAS CALLED TO PICK IT UP. IT HAS NOW BEEN OUT OF SERVICE FOR 18.5 DAYS SINCE APRIL 26, 2010. IT HAS BEEN TAKEN TO THE DEALER FOUR TIMES SINCE APRIL 26, 2010 AND REMAINS THERE AT THIS TIME. DEALER HAS CONFIRMED BATTERY IS ALWAYS AT FULL CHARGE, THEY HAVE CHANGED BOTH STARTER SYSTEM RELAYS, REPLACED THE STARTER, CHECKED TRANSMISSION NEUTRAL POSITION SENSORS. SAFETY ISSUE: LEAVING A FEMALE DRIVER IN AN UNSAFE AND UNPROTECTED SITUATION. DUE TO THE NON STARTING ISSUE. *TR

I PURCHASED A 2011 HYUNDAI SONATA ON 5/11/2010, AND NOTICED THAT THE HORN ISN'T LOUD ENOUGH FOR OTHERS TO HEAR IN HEAVY TRAFFIC. *TR
