2011 Hyundai Sonata Brakes Problems

Your car's braking system has failed multiple times, causing the vehicle to lose power, trigger a brake alarm, and limit your speed to 15 mph. This happened at least three times between the initial failure and January 2026 (at 80,000 miles), sometimes accompanied by loud squealing sounds. The ABS module has been replaced under recall and through independent repair, but the braking failures continue to recur. The repair will likely involve diagnosing and replacing faulty brake system components, possibly including the ABS module, brake pads, or related hydraulic parts.

Your brake warning light came on and your engine shut off while driving. After the dealer performed a recall repair (Campaign 23V651000), the problem happened again. A second dealer diagnosed a failed hydraulic ABS booster sensor and replaced it, but the ABS warning light continues to turn on and off intermittently. The repair may involve replacing the ABS booster sensor, diagnostic work on the brake hydraulic system, or further investigation into related brake components.

The issue has happened multiple times while driving, sitting in traffic, or parked idling. The Brake Light comes on and starts flashing, Alarm Chimes, Brake Pedal goes to the floor seems to not have any hydraulic pressure, the brakes grind like I have no brake pads, and essentially I have NO Brakes. If I turn the car off and on it goes back to normal. I took it to have it checked for a diagnostic code, there were none.

The contact owns a 2011 Hyundai Sonata. The contact stated that while driving at an undisclosed speed, the ABS warning light illuminated. The accelerator pedal was depressed; however, the vehicle failed to accelerate. In addition, the contact stated that the failure reoccurred. The brake pedal was depressed; however the vehicle failed to stop as intended. The contact coasted the vehicle into a parking space. The vehicle was taken to the dealer, where it was diagnosed with HECU failure. The contact was informed that the failure was the result of a failed ABS fuse. The contact was informed that the HECU needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The contact later received notification of NHTSA Campaign Number: 23V651000 (Service Brakes, Hydraulic). The vehicle was taken to the dealer, and the recall repair was performed. The manufacturer was made aware of the failure. The contact requested reimbursement for the previous repair. The request was declined by the manufacturer. The failure mileage was approximately 150,728.

The contact owns a 2011 Hyundai Sonata. The contact stated that while her daughter was driving at approximately 80 MPH, the brake pedal was depressed but was stiff and difficult to depress. The contact stated that her daughter accelerated to steer the vehicle away from slower traffic. The contact stated that her daughter depressed the accelerator pedal however, the vehicle failed to respond and started losing motive power. The contact stated that her daughter was able to steer the vehicle to the side of the road and stop the vehicle. The contact stated that the check engine check brake and several other unknown warning lights were illuminated. The contact had the vehicle towed to an independent mechanic. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 120,000.

Abs unit still in need of remedy Engine emitting smoke and harsh smell no incident has occurred yet but there may be damage occurring to my vehicle

Code p1326; vehicle equipped with YELLOW diptick

The ABS system has had a recall due to the potential for an engine fire. The initial recall was set on 9/22/23. Up until today (12/6/23) no action has been taken by the manufacturer but we are left without a car.

The contact owned a 2011 Hyundai Sonata. The contact stated while driving 30 MPH the battery warning light illuminated. The contact stated that white smoke was issuing from under the hood. The contact stated that he depressed the brake pedal to stop the vehicle, however, the pedal depressed to the floorboard, and the vehicle did not slow. The contact stated that he was able to stop after the engine had stalled. The contact exited the vehicle and observed that flames were issuing from under the front end. The contact stated that the fire department was called and when they arrived the fire had spread to the passenger compartment. The contact stated that the fire department extinguished the fire with water. The vehicle was towed to an impound lot and the contact stated it was later declared a total loss by his insurance provider. The manufacturer was not informed of the failure. The contact had researched online and related the failure to NHTSA Campaign Number: 23V651000 (Service Brakes, Hydraulic). The failure mileage was approximately 200,000.

When Driving the Alarms go off indicating a brake issue, my brake peddle goes to the the floor, car looses power and slows down to 5 MPH. Car will not accelerate past 5 MPH when i am trying to pull over or get off the freeway. Brakes are grinding as i try to use them, very dangerous while on the freeway. When I am able to pull over. I will turn off the car and turn it back on and the issue goes away. Now this may happen several more times before i am able to get some where safe. Dealership has no clue why its doing this after showing the video of the Alarms and describing it. No codes are found either. They just want to start replacing parts stating at 3k a round hoping it will fix the issue. This issue doesn't happen every day but it does happen while driving on the freeway. I have read online others having the same safety issue while driving and having thes same brake failures. Not sure where Hyundai is at with this issue and the fix for it? Yet does someone have to be in a serious accident before someone takes action with this issue?

The ABS system just stopped working while driving, loud brake warning beeps and the brakes stopped functioning making a vibrating sound then stopped working all together, I pulled over as safe as i could and found no leaks , fluid is good. started the car again and after 2 minutes did it again... was told by hyundai that a new abs modulator will be needed but it could not be reset to the computer so I would need a new ECU as well to match....are you kidding,,,thousands of dollars of work and labor ,,,,"""FOR BRAKES,""",,, I bought a money pit not a car...

Without warning, the Sonata stalls while in motion: - the brake pedal goes close to the floor, - the CHECK BRAKE light goes on, - the emergency brake audio alarm and light go on, - the READY light between the fuel and temperature gauges blinks. I have to pull over and turn the car off / on in order to get the car functional again. The speed of the car doesn't seem to matter. This has occurred 11 times over the past year, including 6 times today (7/22/2021) within a span of 15 min, while at speeds between 30- 60 mph. I took the car to the dealer (initially on 6/22/2021). There were no diagnostic error codes and they could not reproduce the problem. I called Hyundai, both on 6/22/2021 and today, to file a report. Hyundai did not provide any insights into the issue. Online, I have read of others having this same issue with Sonatas. Some believe a faulty power brake booster to be the cause.

TL* THE CONTACT OWNS A 2011 HYUNDAI SONATA. THE CONTACT STATED THAT WHILE REVERSING OUT OF HER FRIENDS DRIVEWAY. THE VEHICLE FAILED TO STOP AS THE BRAKE PEDAL WAS DEPRESSED. NO WARNING LIGHTS ILLUMINATED. THE CONTACT STATED THAT THE VEHICLE CAME TO A COMPLETE STOP WHEN IT CRASHED INTO THE CURB. NO INJURIES WERE SUSTAINED. NO POLICE REPORT WAS FILED. NO DAMAGED TO THE VEHICLE. THE DEALER DON DAVIS HYUNDAI (214 HIGHWAY 332 W, LAKE JACKSON, TX 77566) WAS CONTACTED AND INFORMED THE CONTACT THAT NO RECALLS WERE UNDER THE VIN. THE VEHICLE HAS NOT BEEN DIAGNOSED. THE VEHICLE WAS NOT DRIVABLE. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 124,000.

I HAD SMELLING A GAS SMELL COMING FROM THE VENTS ON FRIDAY JULY 19TH ANDI TOOK IT TO FIRESTONE FOR A NEW BATTERY AND A OIL CHANGE. I CALLED THE HYUNDAI DEALERSHIP BECAUSE FIRESTONE TOLD ME ABOUT A NEW RECALL FOR THE FIRE PRESSURE FUEL REGULATOR AND THEY HIGHLY SUGGESTED I TAKE IT INTO THEM. I CALLED HYUNDAI AND THEY SAID FOR ME TO BRING IT IN AND I DIDN'T NEED AN APPOINTMENT SO I TOLD THEM I WOULD BE THERE AROUND 3-4PM YESTERDAY. SO I LEFT WORK EARLY, PICKED UP MY CAR FROM FIRESTONE AND HEADED TO THE DEALERSHIP WHICH WAS ABOUT 10 MILES AWAY. I GOT ON I-35 DOING ABOUT 40MPH OR SO BECAUSE OF TRAFFIC. ALL OF A SUDDEN THE CAR NEXT TO ME STARTS HONKING AND WAVING SAYING MY CARS OF FIRE. I TRY TO APPLY THE BREAK BUT THERE WAS NO PRESSURE. MY INSTRUMENT COLUMN LIT UP LIKE THE 4TH OF JULY AND THEN ALMOST IMMEDIATELY SMOKE STARTS COMING IN FROM THE VENTS, DASHBOARD AND FLOOR. SO MY ONLY OPTION IS TO TUCK AND ROLL DOING ABOUT 35-40MPH ON ONE OF THE BUSIEST HIGHWAYS IN AUSTIN. SO I TUCK AND ROLL, PEOPLE ARE STOPPED TO HELP. I SEE MY CAR CONTINUE TO ROLL INTO THE BARRIER AND WHILE CAR BURST INTO FLAMES.

I WAS DRIVING WEST ON SUNNYSIDE ROAD AFTER LEAVING THE PARKING LOT OF NEW SEASONS. I COULD SEE THAT THE LIGHT WAS RED AND I PULLED OUT ONTO SUNNYSIDE ROAD. IT WAS ABOUT 200 FEET TO THE TRAFFIC THAT WAS STOPPED. I WAS DOING ABOUT 20 MPH WHEN I REALIZED THAT MY CAR WAS NOT GOING TO STOP. I PUSHED HARD ONTO THE BRAKES BUT THE CAR CONTINUED FOREWARD UNDER THE PICKUP IN FRONT OF ME. EVEN WITH THE AIRBAGS DEPLOYED I HAD NO CONTROL. I WAS PUSHING THE TRUCK FOREWARD. THE OTHER DRIVER TURNED ONTO 157TH AVE AND I WAS STILL UNABLE TO STOP THE CAR. I ALSO TURNED RIGHT ONTO 157TH AVE. IT WAS UP HILL I TURNED OFF THE KEY AND IT CAME TO A STOP. MY WIFE WAS PANNICKING AND SO WAS I. THE CAR WAS FILLED WITH SMOKE AND A LOT OF HEAT. MY WIFE WAS SCREAMING FOR SOMEONE TO CALL 911. THE DRIVER OF THE TRUCK RUSHED BACK TO SEE IF WE WERE ALL OK. HE CALLED 911. MY WIFE WAS SORE AS THE AIRBAGS DEPLOYED AND HIT HER IN THE CHEST. SHE HAD PAIN IN HER NECK TOO. I WAS OK AT THE MOMENT. I WAS WORRIED ABOUT THE OTHER DRIVER. HE SAID THAT HE WAS FINE. HE SAID THAT HE HAD TO HONK HIS HORN TO GET THE CAR IN FRONT OF HIM TO MOVE. THEY DID AND HE WAS ABLE TO TURN RIGHT. I AM UPSET WITH RON TONKIN HYUNDAI AS I HAVE HAD TO WAIT ALMOST A MONTH TO GET AN APPOINTMENT FOR MY OIL CHANGE AND THE RECALLS TAKEN CARE OF. THE FIRST RECALL WAS FOR THE AIR BAGS. THE SECOND RECALL WAS FOR THE HIGH PRESSURE FUEL PIPE MAY HAVE BEEN DAMAGED MISALIGNED OR IMPROPERLY TORQUED WHEN THE ENGINE WAS REPLACED ALLOWING THE FUEL TO LEAK. I AM VERY UPSET WITH RON TONKIN HYUNDAI AS I HAVE HAD TO WAIT FOR ALMOST A MONTH TO GET AN APPOINTMENT. JENNIFER LOPEZ THE SERVICE ADVISOR. MY APPOINTMENT WAS SET FOR JUNE 26TH 4 DAYS AFTER THE ACCIDENT. I WENT IN TO CHANGE THE CARS AS I HAVE A 2004 ELANTRA. I HAVE FREE OIL CHANGES ON BOTH CARS. SHE TOLD ME THAT THE RECALLS WERE NOT THE REASON AND ASKED ME IF I WAS GOING TO BUY ANOTHER HYUNDAI.

I HAVE HAD TO REPLACE ALL 4 BRAKE CALIPERS ON MY 2011 HYUNDAI SONATA GLS DUE TO NOT RELEASING AND WEARING OUT BRAKE PADS AND ROTARS. HAS THERE BEEN ANY RECALLS IN REGARDS TO THIS MATTER?

OUR CAR WAS IN THE NUMBER 2 LANE OF A 5 LANE FREEWAY WHEN IT ALL OF A SUDDEN LOST POWER AND THE GAS PEDAL DIDN'T WORK AND THEN A VERY SUDDEN, HARD JOLT IN THE CAR. I WANTED TO DOWNSHIFT, BUT THE SHIFT LEVER WENT TO PARK WITH NO EFFECT. I TURNED ON MY TURN SIGNAL TO GET TO THE SHOULDER ON THE RIGHT. I LET THE WHEELS DRAG ALONG THE ASPHALT CURB OF THE SHOULDER UNTIL I APPLIED THE EMERGENCY BRAKE AND TURNED OFF THE IGNITION, BY THEN, THE SMOKE WAS FILLING THE CABIN COMING THROUGH ALL OF THE AIR VENTS AND MY WIFE AND I GOT OUT AS QUICKLY AS WE COULD. IT WASN'T UNTIL THEN THAT I FOUND THAT WE HAD BEEN FOLLOWED BY A TOW TRUCK WITH ITS EMERGENCY LIGHTS ON AND BLOCKED THE SLOW LANE OF TRAFFIC FOR US AND WHO HAD HIS DISPATCHER CALL THE FIRE DEPARTMENT. THE ENGINE IN THIS CAR HAD BEEN REPLACED IN MARCH, 2018 UNDER A RECALL FOR ENGINE KNOCKING NOISE. THE TOW TRUCK DRIVER TRIED HIS FIRE EXTINGUISHER, BUT IT HAD NO EFFECT AND HE STATED IT WOULD NOT WORK BECAUSE IT WAS A GASOLINE FIRE. NO INJURIES WERE SUSTAINED.IN ORDER TO INSTALL THE NEW ENGINE THEY HAVE TO BEND THE FUEL LINES OUT OF THE WAY AND A FUEL LINE COULD HAVE BEEN KINKED, OR WAS NEVER INSTALLED PROPERLY. NO ONE HAD DONE ANY WORK ON THE ENGINE SINCE IT WAS INSTALLED BY THE HYUNDAI DEALER. I HAVE A FIRE REPORT, BUT IT IS 8 PAGES. HIGHWAY PATROL WAS PRESENT, BUT THEY DO NOT MAKE A REPORT WHEN ONLY 1 CAR IS INVOLVED.

REPLACED REAR BRAKE PADS, ROTORS TWICE WITHIN 2 MONTHS. REPLACING HOSES, CALIPERS, EVEN THOUGH NO SIGN OF LEAK AND CALIPERS EASILY MOVE IN AND OUT. MANUFACTURE PROBLEM/ABS? OUT OF WARRANTY AND DEALER WANTS NOTHING TO DO WITH IT.

MY BRAKE LIGHTS ALL OF A SUDDEN WENT OUT, MY SHIFT LOCK LOCKS EVERYTIME I PUT MY CAR IN PARK I HAVE TO USE SOMETHING TO PRESS THE BUTTON TO UNLOCK MY GEAR SHIFT. GOT IT CHECKED AND IT TURNED OUT TO BE THE BRAKE LIGHT SWITCH

THE BRAKE LIGHTS STAYS ON AS IF PRESSURE IS BEING APPLY TO THEM. CAR BE AT 60 PLUS MILES PER HOURS AND THE CAR COMES TO A SLOW STOP WHILE I'M APPLYING PRESSURE TO THE GAS; HAVING OTHER DRIVERS ALMOST TO HIT ME IN THE BACK.

TAKATA RECALL - IN 2016 THERE WAS A RECALL FOR THE BRAKE LIGHT SWITCH TO BE FIXED ON MY CAR. THEY SAID THAT THEY FIXED IT BUT NOW I AM HAVING THE SAME ISSUES AS MY BRAKE LIGHT SWITCH IS STILL MALFUNCTIONING. MY BRAKE LIGHT STAYS ON THE WHOLE TIME WHEN I AM DRIVING WHICH I HAVE HAD TO REPLACE THE BULBS AS THEY WERE BLOWN AND ONE OF THEM HAD MELTED. AS FAR AS I CAN SEE, IF THIS WAS PROPERLY REPAIRED THEN NONE OF THIS WOULD HAVE BEEN HAPPENING. I HAVE TO CONSTANTLY LIFT MY BRAKE PEDAL TO TURN THEM OFF BEFORE I GET OUT OF THE CAR SO THAT THEY WILL NOT BE ON. THIS HAPPENS WHILE IN MOTION AND STATIONARY

BRAKE LIGHTS STAY ON, AFTER YOU LEAVE OFF BRAKE PEDAL. COULD RESULT IN SERIOUS REAR END ACCIDENT IF PERSON FOLLOWING YOU DOESN'T KNOW WHEN YOU REALLY ARE APPLYING BRAKES. THIS IS BELIEVED TO BE THE BRAKE LIGHT STOPPER PAD. I AM A MECHANIC AND THE STOPPER PAD IS CRUMBLING. PER DEALER IT WAS REPLACED 1/2016 AT 70000 MILE NOW 2YEARS LATER AND 14000 MILE LATER IT IS BAD AGAIN. THIS PROBLEM COULD IMPACT ALL 2011 AND OTHER YEAR MODELS.

I JUST PURCHASED THE CAR MAY 2017. I HAVE HAD NO ISSUES WITH THE CAR. HOWEVER ON SUNDAY AUGUST 20, 2017 MY BREAK LIGHTS WOULD NOT GO OFF. AFTER ABOUT 2 HRS OF TRYING TO GET THEM TO GO OFF. NOTHING. I THEN DID SOME RESEARCH AND VERIFIED THAT THERE WAS A RECALL ON THE ISSUE THAT I WAS HAVING. SO I TOOK IT TO THE HYUNDAI DEALERSHIP. I HONESTLY DONT BELIEVE THAT RECALLS SHOULD HAVE "CLOSE" DATES. NOT EVERY PURCHASES THAT CAR THE YR IT WAS MADE. NONE THE LESS EVEN WITH A RECALL I AM HAVING TO COME OUT OF POCKET ORIGINALLY $101, UNTIL I EXPLAINED MY ISSUES WITH THEM AND THEN IT WENT TO $81. IM STILL A LITTLE ANNOYED THAT A RECALL CAN EXPIRE AND LEAVE THE NEW OWNER WITH PAYING FOR THE ISSUE.

TL* THE CONTACT OWNS A 2011 HYUNDAI SONATA. THE CONTACT STATED THAT THE BRAKE LIGHTS WERE CONSTANTLY ILLUMINATED, EVEN WITH THE VEHICLE TURNED OFF. THE VEHICLE WAS TAKEN TO VOLUME HYUNDAI LOCATED AT: 2520 N. COLUMBIA STREET, MILLEDGEVILLE, GA 31061 TO BE DIAGNOSED.

I WAS DRIVING DOWN FM 2410 IN HARKER HEIGHTS, TEXAS GOING ABOUT 50 MILES AN HOUR THE SPEED LIMIT. CAME UPON A CURVE AND STARTED TO APPLY MY BRAKES TO SLOW DOWN. AS I WAS APPLYING MY BRAKES I HEARD A SCRAPPING SOUND AND THE BRAKE PEDAL SEEMED NOT TO BE FUNCTIONING AS REQUIRED. THE BRAKES LOCKED UP (AS EVIDENCE LOOKING AT THE SKID MARKS SOME 15 TO 20 FEET LONG) THE CAR SEEMED TO BE ACCELERATING INSTEAD OF SLOWING DOWN. AT THE SAME TIME, I WAS TRYING TO TAKE MY FOOT OF THE BREAK AND TURN MY STEERING WHEEL TO REGAIN TOTAL CONTROL OF THE CAR. THE CAR TURN SLIGHTLY TO THE RIGHT AS SHOWN BY THE SKID MARKS WENT OFF THE ROAD THRU THE DITCH ON THE SIDE OF THE ROAD THRU A FIELD FENCE WITH BARB WIRE ON TOP AND INTO A CEDAR TREE AS SHOWN IN THE ENCLOSED PICTURES. *TR

MY BRAKES HAS JUST STARTED MAKING A LOUD, ANNOYING, AND CRACKING NOISE EVERY TIME I PRESS AND RELEASE MY BRAKES. I DO NOT NEED BRAKE PADS, SHOES OR ROTARIES. WHAT!!!!!

MY CAR BATTERY STARTED DYING ON SEVERAL OCCASIONS IN MARCH 2015. ON MARCH 20TH, MY CAR WON'T START AGAIN AND THE REPAIR SHOP SAID THE BATTERY AND STARTER HAD DIED COMPLETELY AND I HAD TO REPLACE IT AT A COST OF $737.79. AFTER THE REPAIRS ON APRIL 13TH, MY CAR WON'T START AGAIN. I TOLD THE REPAIR SHOP THAT I NOTICED THE NIGHT BEFORE THAT MY BRAKES LIGHT WAS NOT GOING OFF. FIRESTONE TOWED THE CAR AT THEIR EXPENSE AND DID THE REPAIR TO THE BRAKES LIGHT AT NO COST BECAUSE I HAD ALREADY PAID CLOSE TO $738 TRYING TO RESOLVE THIS ISSUE. THEY FOUND THE ISSUE WITH 'STOPPER PAD'. I THEN SUBMITTED A REIMBURSEMENT REQUEST TO HYUNDAI FOR CAMPAIGN #136 BUT THEY ONLY REIMBURSED ME FOR $157 AND REFUSES TO REFUND THE BALANCE. MY CAR ON NUMEROUS OCCASIONS DID NOT START. THE ISSUES WITH MY CAR WAS THE BRAKE LIGHT STAYING IN AND KILLING MY BATTERY AND AFFECTING MY CAR IN GENERAL. WHEN FIRESTONE BILLED ME FOR THE REPAIRS THEY SAID SHOULD BE DONE, THE CAR CONTINUED TO HAVE ISSUES UNTIL I NOTICED THE BRAKES LIGHT WAS STAYING ON. FIRESTONE TOWED MY CAR AND REPAIR THE ISSUE AT THEIR EXPENSE. IF IT WAS NOT RELATED WHY WOULD THEY REPAIR MY VEHICLE AT THEIR EXPOSE? I WILL FILE A COMPLAINT WITH NATIONAL SAFETY ADMINISTRATION. THIS IS TOTALLY UNFAIR.

I HAVE NOT RECEIVED AN EXACT ANSWER AS TO WHY WHILE DRIVING ON A CITY STREET, EVERY TIME I PRESS THE BRAKES I HEAR A CLICKING SOUND; WHICH YOU CAN ALSO FEEL BY PLACING YOUR HAND ON THE GEAR SHIFT

TL* THE CONTACT OWNED A 2011 HYUNDAI SONATA. WHILE DRIVING 35 MPH, THE VEHICLE STALLED WITHOUT WARNING AND CRASHED INTO THE REAR OF ANOTHER VEHICLE.

I HAD THE CAR TOWED TO DEALERSHIP, IN FEAR OF DRIVING IT, TO GET OT INSPECTED. MIND YOU, THIS MAKE AND MODEL CAR HAS HAD SEVERAL RECALLS. WHILE IN SHOP THEY FIXED TWO RECALLS #'S 132 AND 136 AND THEN THEY DIAGNOSED THAT THE BRAKE SENSOR MALFUNCTIONED AND THAT THEY HAD TO RECODE IT. I WAS FORTUNATE TO HAVE AVOIDED WHAT COULD HAVE BEEN A MAJOR ACCIDENT. THEY, HYUNDAI, DON'T REALLY WANT TO STAND BEHIND THEIR PRODUCT ONCE IT'S PAST WARRANTY.

THE FRONT BRAKES ON OUR HYUNDAI SONATA FAILED 9/17/15 FORCING MY DAUGHTER OFF THE ROAD USING THE EMERGENCY BRAKE. THIS IS A RESULT OF ON-GOING BRAKE PROBLEMS DATING BACK TO WHEN WE PURCHASED THIS CERTIFIED PRE-OWNED CAR 11/25/13. HYUNDAI REFUSED TO COVER THE REPAIR, SO WE PAID TO HAVE BRAKE PADS, ROTORS AND CALIPERS REPLACED. THIS IS THE 3RD SET OF BRAKES WE'VE PAID TO REPLACE IN LESS THAN 12,000 MILES. AFTER NUMEROUS CALLS AND CORRESPONDENCE WITH HYUNDAI CONSUMER AFFAIRS EXPLAINING THIS IS A LIFE THREATENING PROBLEM CAUSED BY DEFECTIVE BRAKE SYSTEM, THEY DID PAY FOR THE CALIPERS BUT REFUSED TO PAY FOR THE OTHER COMPONENTS. THE FRONT BRAKES HAD GRINDING NOISE SINCE WE BOUGHT THE CAR AND ONLY LASTED 2,743 MILES (DEALER TOLD US THIS CPO CAR HAD BRAND NEW BRAKES), THE SECOND SET ONLY LASTED 9,856 MILES. SINCE THE CALIPER WAS REPLACED 9/21/15, THERE IS NO MORE GRINDING. IT SEEMS CLEAR THAT THE DEFECTIVE CALIPER CAUSED THE PAD AND ROTOR FAILURE, BUT HYUNDAI DENIES THIS. WHEN SPEAKING WITH HYUNDAI CONSUMER AFFAIRS, THEY SAID 1)THEY HAD NO RECORD OF US OWNING THE CAR, 2) HAD NO RECALLS FOR THIS PROBLEM, AND 3) WE DID NOT PURCHASE AN EXTENDED WARRANTY (WE DID). I SUBSEQUENTLY FOUND ON THE HNTSB WEBSITE THAT THERE IS A RECALL FOR THE 2011 HYUNDAI SONATA BRAKES (ATTACHED) INVOLVING THE BRAKE CALIPERS. HYUNDAI HAS BEEN DISHONEST AND DECEITFUL DURING THIS ORDEAL. I WOULD TO FILE AN OFFICIAL NHSTB COMPLAINT AGAINST HYUNDAI TO 1) PREVENT OTHER CATASTROPHIC BRAKE FAILURES AND POTENTIAL FATALITIES, 2) OBTAIN REIMBURSEMENT FROM HYUNDAI FOR THE COST OF REPAIRS ($1,085.68, RECEIPTS ATTACHED) + INCONVENIENCE/TIME/PUNITIVE DAMAGES. ATTACHED ARE COPIES OF CORRESPONDENCE, REPAIR ORDERS, NHTSB RECALL, ETC. THANK YOU FOR ANY HELP YOU CAN PROVIDE.

I WAS ON THE FREEWAY DRIVING AT 65 MPH WHEN THE ENGINE STALLED AND SHUT OFF. THERE WERE NO WARNING LIGHTS INDICATING AN ISSUE WITH THE ENGINE. I WAS INFORMED LATER BY MY MECHANIC THAT THE ENGINE HAD A CATASTROPHIC FAILURE. THE BRAKES FAILED BECAUSE THE ENGINE WAS NOT RUNNING. I WAS LUCKY AND ABLE TO COAST TO THE NEXT EXIT, THE STOP LIGHT WAS GREEN AND I COULD MAKE IT TO SAFE LOCATION. HAD THE ENGINE FAILED A FEW MINUTES EARLIER I WOULD HAVE BEEN IN THE FAST LANE OF THE FREEWAY TRYING TO MAKE IT TO THE SHOULDER. OR TRYING TO STOP AT A LIGHT WITH NO BRAKES.

I PARKED MY CAR AND WHEN I GOT OUT I NOTICE MY BRAKE LIGHTS WOULD NOT GO OFF. I HAD TO GET BACK IN THE CAR PUMP THE BRAKES A FEW TIMES AND THEY FINALLY WENT OUT.

I ADVISED DEALER OF WHAT HAPPENED THEY CHECKED MY BATTERY AND IT WAS FINE HE SAYS MY BRAKE SWITCH LIGHT PAD WAS BAD AND NEEDED TO REPLACED.

I WAS DRIVING THE CAR THIS MORNING AS I APPROACHED A RED LIGHT I APPLIED PRESSURE ON THE BRAKES BUT THE CAR CONTINUED MOVING FORWARD AND LUCKILY STOPPED IN THE MIDDLE OF THE INTERSECTION HAD THERE BEEN A CAR MOVING I COULD HAVE CRASHED INTO IT AS THE CAR COULD NOT STOP - THE BRAKE PEDAL WAS JUST VIBRATING HOWEVER HARD I PUSHED IT - THERE WAS ALSO SNOW ON THE PAVEMENT. *TR

TL- THE CONTACT OWNS A 2011 HYUNDAI SONATA. THE CONTACT STATED WHILE DRIVING AT HIGHWAY SPEED OF 65 MPH THE FRONT DRIVER'S SIDE CALIPER LOCKED AND CAUSED THE VEHICLE TO SWERVE. THE FAILURE WAS EXPERIENCED A SECOND TIME ON THE FRONT PASSENGER SIDE WHILE DRIVING 40 MPH IN SNOWY WEATHER CONDITIONS. THE VEHICLE WAS TAKEN TO THE DEALER AND A DIAGNOSTIC TEST WAS PERFORMED WHICH LOCATED THE FAILURE IN THE BRAKE LINES WHEN THE RUBBER WORE PREMATURELY AND PREVENTED THE BRAKE FLUID TO FLOW TO THE CALIPERS. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE AND CURRENT MILEAGE WAS 55,000. RK

HYUNDAI SONATA 2011 PUSH BUTTON START. I AM THE ORIGINAL OWNER OF THE VEHICLE. YESTERDAY I WENT INTO MY CAR AND PROCEEDED TO START MY CAR. I HAD TO PUSH THE START BUTTON THREE TIMES BEFORE IT ACTUALLY STARTED UP. THIS HAPPENED TWICE WITHIN 2 HOURS. 5 DAYS PRIOR MY VEHICLE HAD BEEN TO THE HYUNDAI DEALERSHIP FOR THE RECALL ON THE STOP LAMP SWITCH. AN EXISTING RECALL (NHTSA CAMPAIGN NUMBER: 13V113000) INDICATES THAT FOR THE 2011 HYUNDAI SONATA THE STOP LAMP SWITCH MAY NOT FUNCTION CORRECTLY. THEY, THE DEALERSHIP,PERFORMED THE SERVICE AND REPLACED THE STOPLAMP SWITCH. AS RESULT MY CAR IS EXPERIENCING INTERMITTENT SWITCH POINT CONTACT WITH THE PUSH-BUTTON START. THIS IS CRAZY. *TR

2011 HYUNDAI SONATA. CONSUMER WRITES IN REGARDS TO VEHICLE BRAKE MALFUNCTION. *SMD THE CONSUMER STATED APPROXIMATELY 15 TIMES DURING THE 24 MONTHS HIS WIFE OWNED THE LEASED VEHICLE, WHEN SHE APPLIED THE BRAKES, MOSTLY AT LOW SPEEDS AND ONCE IN REVERSE, SHE EXPERIENCED A FIRM PEDAL RESISTANCE, BUT NO FUNCTIONAL BRAKING FOR SEVERAL SECONDS.

I WAS DRIVING IN TOWN @ SLOW SPEED, & PUT ON BRAKES TO STOP AT A STOP SIGN/CROSS WALK. I BEGAN TO BRAKE A CAR & HALF LENGTH FROM THE CROSS WALK. THE CAR DID NOT STOP & I FELT IT PULL FORWARD, FELT A VIBRATION IN THE BRAKE PEDDLE & HEAR THE MOTOR MAKING A LOW REVVING OR WHINING SOUND. THE CAR WENT THROUGH THE CROSS WALK & INTO THE MIDDLE OF THE INTERSECTION. AT THAT POINT I TOOK MY FOOT OFF THE BRAKE & DROVE ON UNTIL I FOUND A PLACE TO PULL OVER. THE BRAKES WERE FINE WHEN I STOPPED THE CAR AT THE PARKING SPOT. I LEFT THE CAR RUNNING & CALLED MY HYUNDAI DEALERSHIP. EXPLAINED THE PROBLEM & EXPLAINED THAT I WAS ALARMED BY THIS. THE GUY TOLD ME IT WAS PROBABLY MY ABS BRAKES KICKING IN AS IT WAS RAINING. I HAVE DRIVEN CARS FOR YEARS WITH ABS BRAKES & HAD THEM KICK IN & THIS DID NOT FEEL THE SAME. THIS FELT LIKE MY CAR WAS PULLING FORWARD RATHER THAN ABS BRAKES ACTIVATING. I COULD NOT STOP THE CAR WITH MY FOOT ON THE BRAKE PEDDLE. THIS IS THE SECOND TIME THIS HAS HAPPENED IN THE LAST 5 MONTHS. BUT I DON'T HAVE THE DATE OF THAT INCIDENT. BOTH TIMES I CALLED THE DEALERSHIP. I WAS TOLD TO KEEP DRIVING THE CAR TODAY & IF IT DOES IT AGAIN TO SCHEDULE AN APPOINTMENT AS THEY HAVE HAD SOME PROBLEMS WITH THE ABS BRAKES. I AM GOING ON VACATION IN A COUPLE OF DAYS & THE DEALERSHIP IS 50 MILES AWAY, SO I CAN'T JUST STOP BY WHEN THIS HAPPENS. MY CONCERN, WHICH I EXPRESSED TO THE DEALERSHIP, IS THAT IF SOMEONE HAD BEEN IN THE CROSS WALK I WOULD HAVE HIT THEM AS I HAD NO WAY TO STOP THE CAR AND IT WAS PULLING FORWARD. OR IF I CAR HAD BEEN COMING THROUGH THE INTERSECTION, I WOULD HAVE BEEN HIT AND IT WOULD HAVE BEEN MY FAULT. I AM LESS THAN 3000 FROM MY WARRANTY BEING UP AND TOLD THE DEALERSHIP TO MAKE A NOTE OF THIS AS A PROBLEM AT THIS POINT. I SEE WHERE THERE ARE OTHERS WHO HAVE HAD THE EXACT SAME PROBLEM. I AM VERY CONCERNED THAT THIS IS A DANGEROUS SITUATION WITH THIS CAR. *TR

3 TIMES ON JANUARY 22, MY BRAKES SCREAMED AND FAILED, ALMOST CAUSING ME TO CRASH. SINCE THEN, ONCE IN THE RAIN, AS I APPLIED THE BRAKES, THE ENGINE REVVED VERY NOISILY AND THE BRAKES FAILED, AGAIN NEARLY CAUSING AN ACCIDENT. NOW, EVERY TIME I TAKE MY FOOT OFF THE GAS PEDAL AND/OR APPLY THE BRAKES, THE ENGINE REVS. THIS IS A VERY DANGEROUS SITUATION. HYUNDAI HAS TOLD ME THIS INCIDENT IS NOT COVERED BY THEM. *TR

BACKING OUT OF MY DRIVE WAY INTO THE STREET, BRAKES DID NOT WORK AND ACCELERATED. I DAMAGED THE BACK OF MY CAR AND DRIVERS SIDE DOOR. HIT NEIGHBORS MAILBOX. *TR

THE BRAKE DOES NOT RELEASE. AS YOU DRIVE THE BRAKE SMOKES AND RUBS CAUSING YOU TO STEP HARDER ON THE GAS TO MOVE FORWARD. EVENTUALLY YOU HEAR THE BRAKE RELEASE AND IT DRIVES NORMALLY. I HAD A NEW CALIPER , ROTOR AND BRAKE PAD PUT ON 2 WEEKS AGO FOR THE SAME ISSUE. *TR

1) WITHIN THREE MONTHS OF BUYING THIS CAR, STARTING ISSUES BEGAN. GENERALLY ON THE SECOND START OF THE DAY. FIRST START OF THE DAY USUALLY INVOLVES HIGH ENGINE REVVING SOMEWHERE IN THE NEIGHBORHOOD OF 2,500 RPM. AFTER A SHORT TRIP, IGNITION WILL NO CLICK OVER ATTEMPT TO RESTART. USUALLY SECOND OR THIRD TRY RESULT IN A START. DESPITE DEALER REPLACEMENT OF STARTER, FUEL PUMP AND BATTERY, THE PROBLEM CONTINUES PERIODICALLY. 2) REAR BRAKES NEEDED REPLACEMENT AT 24K MILES. WEAR WAS UNEVEN: LEFT BRAKE WAS GRINDING INTO ROTOR AND RIGHT BRAKE WAS ONLY ABOUT 50 PERCENT WORN. HAD DEALERSHIP CHECK FOR POSSIBLE FAULTY CALIPERS, BUT THEY CLAIMED THEY FOUND NO ISSUES AND WOULD NOT COVER UNDER WARRANTY. IN CONTRAST, THE CAR STILL HAS THE ORIGINAL FRONT BRAKES. *TR

DIFFICULTY DEPRESSING BRAKE PEDAL IN ORDER TO START ENGINE...THIRD TIME ...DEALER REPLACED BRAKE SWITCH OTHER TWO TIMES. *TR

TL* THE CONTACT OWNS A 2011 HYUNDAI SONATA. THE CONTACT STATED THAT WHILE DRIVING 75 MPH, THE VEHICLE STALLED WITHOUT WARNING. THE CONTACT WAS ABLE TO RESTART THE VEHICLE AS THE VEHICLE FUNCTIONED NORMALLY. THE VEHICLE WAS TAKEN TO THE DEALER FOR INSPECTION WHERE THEY STATED THAT THE BRAKE SWITCH NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED BUT THE FAILURE RECURRED SPORADICALLY. THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS 24,000.

TL* THE CONTACT OWNS A 2011 HYUNDAI SONATA. THE CONTACT STATED THAT WHILE DRIVING 50 MPH, SHE ENGAGED THE BRAKES BUT THE VEHICLE DID NOT STOP. THE VEHICLE WAS TAKEN TO THE DEALER, WHO WAS UNABLE TO DIAGNOSE THE FAILURE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND OFFERED NO ASSISTANCE BECAUSE THE DEALER WAS UNABLE TO DIAGNOSE THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 7,500 AND THE CURRENT MILEAGE WAS 8,500.

THE 2011 SONATA IS UNABLE TO START BY PRESSING DOWN ON BOTH THE BRAKE PEDAL AND START BUTTON. I HAD THIS PROBLEM FOR OVER 3 MONTHS. THIS FAILURE HAPPENS ABOUT 1-2 TIMES A WEEK. ONCE FAILED TO START, THE BRAKE PEDAL LOCKED UP WHILE THE DASHBOARD DISPLAY STILL SAYS "PRESS DOWN BRAKE PEDAL TO START." WITH REPEATED TRIES TO START THE CAR, IT SOMETIMES STARTED AFTER 5-10 MINUTES, BUT SOMETIMES IT TOOK OVER 1 HOURS TO START THE ENGINE. HYUNDAI DEALERSHIP SAID THEY CANNOT HELP BECAUSE THE PROBLEM CANNOT BE REPRODUCED WHEN THEY SERVICE THE CAR. IT IS A RATHER NEW CAR BUT VERY UNRELIABLE. *TR

IN THE LAST MONTH OF MARCH 2012, WHEN DRIVING IN TOWN OR ON THE HIGHWAY, MY ESC LIGHT WILL COME ON FOR NO REASON IN PERFECT WEATHER CONDITIONS AND THEN WHEN I STOP SOMEWHERE E.G. TO LET MY CHILD OUT IN THE SCHOOL LINE, I WILL PUT MY CAR IN PARK, IF THIS IS AN OCCASION THAT MY ESC LIGHT HAS COME ON IT WILL NOT LET ME TAKE MY CAR OUT OF PARK, UNLESS I TURN THE CAR ON AND OFF SEVERAL TIMES, ALSO WHEN THE ESC LIGHT COMES ON THERE IS A PRETTY BIG DELAY IN MY BRAKES AND ACCELERATIONS. I AM WORRIED ABOUT MY CHILDREN'S SAFETY WHILE IN MY CAR BECAUSE I AM NOT SURE IF ONE DAY IT MAY CAUSE A SERIOUS ACCIDENT BUT I HAVE SEARCHED EVERY WHERE AND CAN NOT FIND A RECALL ON THIS. *TR

TL* THE CONTACT OWNS A 2011 HYUNDAI SONATA. THE CONTACT STATED THAT WHEN DRIVING IN RAINY WEATHER AND APPLYING THE BRAKES, THE BRAKE WOULD EXHIBIT A LOUD, GRINDING NOISE. THE VEHICLE WAS TAKEN TO THE DEALER WHO TEST DROVE THE VEHICLE AND WAS ABLE TO RECREATE THE FAILURE. THE DEALER ADVISED THE CONTACT THAT THE NOISE WAS NORMAL AND THAT ALL BRAKES ON NEW VEHICLES WOULD EXHIBIT THE NOISE. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 6,500 AND THE CURRENT MILEAGE WAS 6,560.

ADD ON TO ODI # 10440320 I WAS DRIVING AND TWICE WHEN I TRIED TO STOP TO MAKE A TURN THE ENGINE KEPT OVERRIDING THE BRAKE AND THE CAR KEPT LURCHING AHEAD. I APPLIED THE BRAKE PEDDLE AS HARD AS I COULD AND THE CAR WOULD NOT STOP. WHEN I RELEASED THE BREAK PEDDLE, THE CAR STARTED ACTING NORMAL AGAIN. BY THIS TIME I WAS WAY OVER THE CENTER LINE OF THE ROAD AND IF THERE HAD BEEN ANOTHER CAR AT THE INTERSECTION I WOULD HAVE CERTAINTY HIT THEM. THIS IS THE SECOND AND THIRD TIME THIS HAS HAPPENED WITH THIS CAR AND I BELIEVE IT SHOULD BE TAKEN OFF THE ROAD BEFORE SOMEONE GET KILLED. IF I WAS PULLING UP BEHIND ANOTHER CAR AT A STOP SIGN AND THIS HAPPENED I WOULD REAR END THE CAR IN FRONT. IF I WAS STOPPING AT A PEDESTRIAN CROSSING AND THIS HAPPENED I COULD RUN SOMEONE OVER AND KILL THEM. *TR

I WAS PULLING INTO PARKING SPACE, HAD MY FOOT ON THE BRAKE, CAR WAS ALMOST COMPLETELY STOPPED, ALL OF A SUDDEN THE CAR ACCELERATED, TRAVELED APPROXIMATELY 8 FEET, THE BRAKE DIDN'T STOP THE CAR. I HIT THE BRICK WALL OF A BUSY CONVENIENCE GAS STATION STORE, THANKFULLY NO ONE WAS COMING OUT THE DOOR AT THE TIME. MY FIRST THOUGHT WAS THE FLOOR MAT HAD INTERFERED WITH THE GAS PEDAL, BUT AM SURE NOW THAT WAS NOT THE CASE. WHEN A REPRESENTATIVE OF MY INSURANCE COMPANY CALLED ME, HE STATED THAT HE HEARD THAT I HAD STEPPED ON THE GAS PEDAL INSTEAD OF THE BRAKE, THIS IS NOT TRUE, I AM 100 PERCENT SURE. MY HUSBAND WAS A PASSENGER IN THE CAR AND AFTER WE HAD CALMED DONE, WE DISCUSSED WHAT HAD HAPPENED, HE STATED TO ME THAT THE CAR WAS ALMOST STOPPED AND THEN JUST SUDDENLY MADE A LOUD ROARING SOUND AND ACCELERATED. OUR CAR WAS TOWED TO A HYUNDAI REPAIR STATION AND WE ARE WAITING TO HEAR HOW MUCH THE DAMAGES ARE. JUST THE THOUGHT OF HAVING TO DRIVE THAT CAR AGAIN SCARES ME, IT WAS A VERY FRIGHTENING EXPERIENCE, AS IT HAPPENED SO FAST AND I HAD NO CONTROL OVER STOPPING THE CAR, OTHER THAN MY FOOT WAS ON THE BRAKE AND THAT DIDN'T STOP THE ACCELERATION. MY HOPE IS THAT THIS IS INVESTIGATED BEFORE ANY SERIOUS INJURIES OR DEATHS OCCUR. *TR

TL* THE CONTACT OWNS A 2011 HYUNDAI SONATA. THE CONTACT STATED THAT THE PUSH TO START BUTTON SWITCH FAILED. WHEN DEPRESSING THE BRAKES AND TRYING TO PLACE THE VEHICLE INTO GEAR, THE VEHICLE WOULD NOT MOVE. THE FAILURE RECURRED ON AN INTERMITTENT BASIS. THE VEHICLE WAS TAKEN TO THE DEALER AND THEY ADVISED HIM THAT THE BRAKE SWITCH FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED FOR THE BRAKE SWITCH. THE FAILURE MILEAGE WAS APPROXIMATELY 24,000. THE VIN WAS UNAVAILABLE.

TL* THE CONTACT OWNS A 2011 HYUNDAI SONATA. WHILE MERGING INTO ANOTHER LANE, THE CONTACT STATED THAT THE BRAKES WERE DEPRESSED AND FAILED TO ENGAGE. THE CONTACT PULLED THE EMERGENCY BRAKE IN ORDER TO STOP THE VEHICLE. THE TRUNK WOULD ALSO OPEN INADVERTENTLY. THE DEALER REPAIRED THE FAILURE BY REPLACING THE MASTER CYLINDER AND MODULE FOR THE BRAKING SYSTEM AND ALSO ADVISED THE CONTACT TO OPEN THE TRUNK MANUALLY. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND FILED A REPORT. THE FAILURE MILEAGE WAS 12,500 AND THE CURRENT MILEAGE WAS 14,000. THE VIN WAS UNAVAILABLE.

TONIGHT I WAS REAR ENDED BY A WOMAN IN AN SUV, WHO'S BRAKES DID NOT WORK IN HER DURANGO, SHE SAID. THERE WERE NO SKID MARKS INDICATING AN ATTEMPTED STOP. HER IMPACT ON MY VEHICLE WAS SEVERE. POLICE OFFICER GUESSED SHE WAS GOING 40 MPH WHEN SHE HIT MY CAR. MY CAR WAS SHOVED FORWARD INTO THE CAR IN FRONT OF MINE, THAT CAR THEN HIT THE CAR IN FRONT OF IT. THERE WERE 3 CARS, MINE LAST IN LINE, SITTING AT A RED LIGHT. WE WERE ALL STOPPED. THEN THERE WAS A 4TH CAR THAT HIT MINE FROM BEHIND. THE MATTER IM REPORTING IS THAT THE AIRBAGS IN MY HYUNDAI SONATA SE 2011 CAR DID NOT DEPLOY WHEN I THEN HIT THE CAR IN FRONT OF ME. THE IMPACT WAS GREAT ENOUGH TO CAUSE THAT CAR TO THEN HIT ANOTHER CAR AND THAT CAUSED A CRACK IN THE RADIATOR OF THE CAR IN FRONT OF MINE. ALSO, AFTER I HIT THAT CAR IN FRONT OF ME, I THEN BOUNCED BACK ABOUT 10 FEET. MORE EVIDENCE OF IMPACT. WHY NO AIRBAGS? I DID NOT SEE VERY MUCH DAMAGE TO THE FRONT OF MY CAR NOR THE BACK OF THE CAR THAT WAS DIRECTLY IN FRONT OF MINE, WHILE THE BACK OF MY CAR WAS BAD ENOUGH THAT I EXPECT TO BE TOLD IT IS NOT REPAIRABLE.. IM REPORTING JUST IN CASE YOU RECEIVE ANY OTHER REPORTS INDICATING THERE IS SOMETHING FAULTY CONCERNING AIRBAGS IN THE HYUNDAI. I KNOW AIRBAGS ARE NOT TO DEPLOY IN REAR END COLLISION BUT SINCE I THEN HIT ANOTHER CAR FRONTALLY, I WOULD THINK THE AIRBAGS WOULD DEPLOY. MY HUSBAND WAS IN THE PASSENGER, FRONT SEAT AND IN ORDER TO BRACE HIMSELF, HE PUT HIS HAND UP AT THE WINDSHIELD. THE GLASS WAS BROKEN IN AN AREA THE SIZE OF A CANTALOUPE FROM THE IMPACT AGAINST HIS HAND. IM THINKING THE IMPACT MUST HAVE BEEN MODERATE TO SEVERE. ON THE UP SIDE, MY SONATA TOOK THAT HIT AND SUSTAINED THE DAMAGE TO THE OUTSIDE AND UP INTO THE AIR AT THE TRUNK RATHER THAN INTO THE CAB OF THE CAR. MY FATHER AND SON WERE IN THE BACKSEAT AND WERE NOT KILLED, I THINK BECAUSE THE CAR IS A GOOD, SAFE VEHICLE IN A CRASH. *TR

FAILED COMPONENTS: BRAKES & SHIFT GEAR THE BRAKE PEDAL IS NOT WORKING MOST OF THE TIME WHEN SHIFTING THE GEAR FROM PARK TO DRIVE MODE (FOLLOWED BY REVERSE MODE) I NEED TO PRESS THE BRAKE PEDAL VERY HARD UP TO SEVERAL TIMES TO SHIFT THE GEAR. I BROUGHT THE VEHICLE TO THE DEALER AND IT WORKS FINE FOR TWO DAYS. IT STARTED HAPPENING AFTER TWO FIRST SERVICES TO THE VEHICLE BY DEALER. I BROUGHT THE VEHICLE AGAIN TO DEALER AFTER 1 WEEK AND EXPLAINED THE PROBLEM AGAIN. THEY DID SOME TROUBLESHOOTING AGAIN, THEY TOLD ME THAT THEY DIDN'T IDENTIFY THE PROBLEM THIS TIME. I SPOKE WITH HYUNDAI CUSTOMER SUPPORT AND THEY DIRECTED ME TO ANOTHER DEALER AND ASKED ME TO DOCUMENT THE PROBLEM. I TOOK THE VEHICLE TO ANOTHER DEALER AND THEY TOLD ME THAT THIS IS A COMMON ISSUE AND SUGGESTED THAT I UNLOCK THE "SHIFT LOCK" IN CASE OF EMERGENCIES! I TOLD THEM THAT SHIFT LOCK IS ONLY USEFUL IN CASE OF EMERGENCIES. BUT THE BRAKE PEDAL IS NOT RELEASING THE GEAR MOST OF THE TIME WHICH IS NOT ACCEPTABLE. THERE IS NO ANSWER FROM THE DEALER. TRYING TO CONTACT HYUNDAI OFFICIAL SUPPORT BUT NOTHING HEARD BACK FROM THEM AT (AFTER 2 WEEKS.) STATUS UPDATE 02/23/12

COMING OUT OF SIDE STREET, GOING ABOUT 5-10 MPH. DEPRESSED BRAKE TO STOP/SLOWDOWN AND CAR (2011 HYUNDAI SONATA PURCHASED IN FEBRUARY 2010) JUST KEPT ON GOING INTO INTERSECTION AND UP THE ROAD. KEPT PRESSING PEDAL ALL THE WAY TO FLOOR AND CAR STILL KEPT GOING UNTIL IT GLIDED TO A STOPPED. TRAVELED ABOUT 100-150 FEET WITH NO BRAKES AND HAD USE HORN A FEW TIMES TO WARN OTHER DRIVERS. AFTER THIS I MOVED AGAIN AND BRAKES WORKED FINE. VERY SCARY... WENT OUT INTO A VERY,VERY BUSY STREET. FORTUNATELY I HIT NO ONE AND NO OTHER CARS HIT ME. WILL CALL DEALER TO REPORT IT AND ASK FOR FURTHER ADVICE. PERHAPS ICE, SNOW, SAND, ETC. GOT INTO PADS/CYLINDERS AND TEMPORARILY SEIZED THE BRAKES? DON'T HAVE VIN WITH ME WILL REPORT IT LATER. *TR

I PURCHASED THE 2011 HYUNDAI SONATA JUNE 2010. I WAS REALLY ENJOYING THE NEW SLEEK LOOK OF THE SONATA. I HAVE NEVER OWNED ANY TYPE OF HYUNDAI VEHICLE BEFORE. WELL AS I BEGAN TO DRIVE THE VEHICLE - I NOTICED THAT THERE WAS A BIT TOO MUCH SKIDDING ON WATER OR DURING RAIN FALL. THIS WAS DURING A SIMPLE TAKE OFF FROM A STOP. JANUARY 2011 I WAS TRAVELING AT ABOUT 35 MILES PER HOUR LIGHT SNOW WAS FALLING BUT THE ROADS WERE CLEAR. AS I WAS APPROACHING TRAFFIC AHEAD THE LIGHT TURNED GREEN AND TRAFFIC BEGAN TO MOVE. I NOTICED THE CAR IN FRONT OF ME NOT QUITE TAKING OFF WITH TRAFFIC SO I BEGAN TO BRAKE. TO MY SURPRISE - GUESS WHAT - THE CAR WAS NOT STOPPING. MY NICE PICTURE OF THE SKIDDING CAR LITE UP AND THE VIBRATION UNDER THE BRAKE PEDAL STARTED. SO I LET OFF AND PRESSED AGAIN AND THERE WAS STILL NO STOPPING. I BEGAN TO BLOW MY HORN IN A PANIC TO WARN THE DRIVER AHEAD I WAS COMING. (WELL AS YOU ALL MAY OR MAY NOT KNOW - THE HORN IS PRETTY LOUSY AND ACCORDING TO THE OTHER DRIVER - AFTER I HIT HIM - HE DIDN'T REALIZE IT WAS MY CAR UNTIL IT WAS TOO LATE.) I LITERALLY HAD MY FOOT PRESSED TO THE FLOOR BLOWING THE HORN AND TRYING TO STOP THIS CAR BUT TO NO AVAIL IT DID NOT UNTIL WE COLLIDED. THANK GOD THERE WAS ONLY CRACKED BUMPERS INVOLVED BUT IT TRULY COULD HAVE BEEN SO MUCH WORSE. I AM TRULY AFRAID TO DRIVE THIS CAR IN THE VARIOUS ELEMENTS NOW BECAUSE I JUST DON'T KNOW WHAT TO EXPECT AND THE NEXT TIME WILL I BE ALIVE TO TELL ANOTHER STORY. PRETTY SCARY. *TR

2011 SONATA 2.0T. NO BRAKING PRESSURE WHEN COLD, SLOW TO STOP UNTIL CAR WARMS UP, NOISE IS HEARD FROM WHAT SOUNDS LIKE THE ABS PUMP OR POWER BRAKE ASSIST PUMP. TOOK TO A DEALER AND WAS TOLD THE NOISE IS A STRUT TOWER BAR AND MOTORWORLD GROUP IN WILKES-BARRE REFUSES TO LOOK ANY FATHER ON THIS ISSUE UNLESS I PAY TO HAVE THE TOWER BAR REMOVED AND RECHECKED. I HAVE 1500 MILES ON THE CAR AND DEALER IS REFUSING TO CORRECTLY DIAGNOSE ISSUES UNLESS I PAY FOR IT. THIS IS A 2011 SONATA 2.0T SE. THE SOUND IS DEFINITELY NOT THE TOWER BAR AS I CAN REMAKE THE SOUND ON OTHER CARS AFTER USING BRAKES VERY HARD. THESE BRAKES ARE VERY SOFT AND THE NOISE IS EASY HEARD AND SOUNDS LIKE A PUMP AND A VIBRATION IN THE PEDAL. *TR

OUR NEW CAR ROLLS A LITTLE BIT AFTER APPLYING THE EMERGENCY (PARKING) BRAKE. *TR

BRAKES FAILED WHEN TRYING TO STOP AT RED LIGHT AT EXIT TO PARKING LOT DRIVING BETWEEN 5-10 MILES PER HR. PRESSED ON BRAKE - DID NOT GO DOWN. NO RESPONSE - CAR KEPT MOVING UNTIL I PUT GEAR IN PARK AND HIT THE TRUCK STOPPED AT THE LIGHT. DRIVING A 2011 HYUNDAI SONATA PURCHASED ON 5/31/10. *TR
