Hyundai is recalling certain model year 2006-2010 Sonata vehicles manufactured March 1, 2005, through January 21, 2010; and model year 2006-2011 Azera vehicles manufactured September 27, 2005, through November 22, 2010 originally sold in, or currently registered in, Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin and the District of Columbia. Road salt and water can enter portions of the rear crossmember, leading to corrosion of the crossmember steel. This may lead to detachment of one of the rear control arms.
Control arm separation may suddenly change the rear wheel alignment, affecting the handling of the vehicle, increasing the risk of a crash.
Hyundai will notify owners, and dealers will repair or replace the crossmember assembly. The recall began on October 8, 2013. Owners may contact Hyundai Customer Care Center at 1-800-633-5151. Hyundai's recall number is 113.

Hyundai Motor Company (Hyundai) is recalling certain model year 2006-2009 Accent, model year 2007-2011 Azera, Sonata and Sante Fe,2006-2011 Tucson, 2009-2011 Elantra Touring, 2007-2010 Elantra, 2008-2011 Veracruz, 2009-2011 Genesis, 2010-2011 Genesis Coupe, 2007-2008 Entourage, and 2006-2008 Tiburon vehicles. Originally, in April 2013, Hyundai recalled 1,059,824 model year 2007-2009 Accent and Tucson, model year 2007-2010 Elantra, model year 2007-2011 Santa Fe, model year 2008-2009 Veracruz, model year 2010-2011 Genesis Coupe, and model year 2011 Sonata vehicles. In September 2013, Hyundai informed the agency that it was adding more vehicles to this campaign, representing an additional 652,512 units. The total number of vehicles being recalled is now 1,712,336. In the affected vehicles, the stop lamp switch may malfunction. A malfunctioning stop lamp switch may cause the brake lights to not illuminate when the brake pedal is depressed or may cause an inability to deactivate the cruise control by depressing the brake pedal. Additionally, a malfunctioning stop lamp switch may also result in intermittent operation of the push-button start feature, affect the operation of the brake transmission shift interlock feature, preventing the shifter from being moved out of the PARK position and cause the Electronic Stability Control (ESC) malfunction light to illuminate.
Failure to illuminate the stop lamps during braking or inability to disengage the cruise control could increase the risk of a crash. Additionally, when the ignition is in the 'ON' position, the transmission shifter may be able to be moved out of Park without first applying the brake. This may lead to unintentional movement of the car which may increase the risk of a crash.
Hyundai will notify owners, and dealers will replace the stop lamp switch, free of charge. The safety recall began on April 22, 2013. Owners may contact Hyundai at 1-800-633-5151. Hyundai's recall campaign number is 110.

Subject: Non-Collision Engine Compartment Fire - 2010 Hyundai Sonata (VIN: [XXX] ) "On dec 19 2025, my 2010 Hyundai Sonata suffered a sudden, non-collision fire that originated in the engine compartment. While there are currently no 'open' recalls on this VIN, I am formally reporting this incident as it matches the failure patterns documented in NHTSA Defect Petition DP18-003 regarding non-crash fires in Hyundai/Kia vehicles. Preliminary inspection of the damage shows characteristic signs of a manufacturer defect, specifically potentially related to a connecting rod bearing failure leading to an engine block puncture and oil ignition, or an electrical short in the ABS module—both of which have been subjects of major Hyundai fire investigations and class-action settlements (e.g., Engine II settlement) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2010 Hyundai Sonata. The contact stated that upon attempting to turn the ignition key in the ignition switch to start the vehicle, the ignition switch failed to turn, and the steering wheel locked. The vehicle was towed to an independent mechanic, where the ignition switch was replaced; however, the vehicle failed to start. The mechanic determined that an unknown part needed to be replaced. The mechanic contacted the manufacturer for parts and was informed that the unknown part had been discontinued. The vehicle was not repaired. The failure mileage was unknown.

The plastic housing of the brake lights have turned black. I'm on my second set that I got at wrecking yard. The plastic doesn't hold up to the heat of the tail/brake light. I saw other cars like mine with same problem at the wrecking yard. And my ground wire to my radiator fan burned out as well during COVID. I think Hyundai used cheap plastic that can't hold up to the heat. My dash cracked really bad as well. All over. I saw the same cracked dashes of other car in wrecking yards. They know they had a plastic defect and they changed body styles the next year. My door handles brake off in my hands and the a/c vent broke twice. They have hazzard car because all of this happened early when I purchased the car. And my car has Hyundai and Kia parts old body style 2010 bought end of 2009. Theta 2 engine. All of the recalls but they leave my car out. And that stop brake switch light has broken so many times. Replaced free only 1 time by dealership. Other times I had to pay for. Cheap plastic. If I need repair by dealership , I have to leave car on their lot for 6weeks for them to look at. Not appointment. Leave my car on lot until it's my cars turn. And my car just quit running once while driving in my apartment complex. It also quit running driving down the highway.. everything shutting off and lights turned on dash. The battery light was on first, then the check engine , abs, and all lights coming on. I tried to turn on my hazards but everything was failing. I was lucky I wasn't hit by other highway traffic. My headlights went off or really dim. I was allowed to drive really slow to a roach hotel just there on interstate. I was told it was my alternator. But I think it was something else that caused failure. I did have my car professionally washed, that day. (Hardly do that). And the week before it was at Hyundai shop for retinting of windows which my battery was dead in their dusty lot when pickup. That brake light switch lamp stopper was broken and laying in floor l

WHEN YOU TURN THE KEY OVER EVERYTHING COMES ON AND EVERYTHING WORKS EXCEPT THE STARTER. I HAVE REPLACED 3 STARTERS AND THE CAR DOESN'T EVEN HAVE 103,000 MILES ON IT. I TURNED THE CAR OFF OUTSIDE OF THE STORE. I CAME BACK OUT TURNED THE KEY AND NOTHING. I WAS STRANDED AGAIN! I'M THINKING IT'S SOMETHING ELSE.

MY CAR WON'T START. IT SOUNDS LIKE IT TRIES TO START THEN ALL YOU HEAR IS THE STARTER SPINNING. I HAD MY VEHICLE TOWED TO THE NEAREST HYUNDAI DEALERSHIP. THE SERVICE ADVISOR AT THE DEALERSHIP EXPLAINED THAT THE STARTER LEVER ARM NEED TO BE REPLACED. THE PLASTIC PART IS KNOWN TO BE FAULTY, AND HYUNDAI REFUSES TO PERFORM A RECALL TO REPLACE THE PLASTIC PART WITH A METAL PART. TO MAKE MATTERS WORSE-THE STARTER LEVER ARM COST ABOUT $8.15 TO REPLACE HOWEVER THE DEALERSHIP INSIST ON CHARGING $400 TO REPLACE THE BROKEN PLASTIC LEVER ARM. I AM A SECOND OWNER, AND HAVE 75K MILES ON MY VEHICLE; THEREFORE I DO NOT HAVE A WARRANTY ON THE PART.

THE ELECTRONIC STABILITY CONTROL (ESC) TURNS OFF RANDOMLY BY ITS SELF WHILE THE CAR ENGINE IS ON. PRESSING THE ESC BUTTON TO TURN ESC BACK ON DOES NOT WORK. TURNING OFF THE ENGINE AND THEN TURNING IT BACK ON SOMETIMES TAKES CARE OF THE PROBLEM. WHEN THE ESC IS OFF, THE BREAKING SYSTEM IS SEVERELY AFFECTED WHERE EVEN WITH A RELATIVELY LIGHT PRESS ON THE BRAKES CAN RESULT IN THE LOCKING OF THE TIRES. *TR

AS I WAS DRIVING TO MAKE A TURN THE CAR SHUT DOWN WITHOUT WARNING. IT HAS HAPPENED TWO OTHER TIMES SINE THIS FIRST INCIDENT. CAR SHUT DOWN AS I WAS GOING VARIOUS SPEEDS. THE CRANKING OF THE IGNITION IS ALSO A PROBLEM. I FIRST REPORTED THIS TO THE DEALER IN 2011. IT CRANKS AS IF IT IS ABOUT TO DIE THEN IT HAS EVENTUALLY CAUGHT AND TURNED ON. THIS IS AN ONGOING ISSUE. SINCE IT DOESN'T SHOW A CODE OR ACT UP WHEN I AM IN FOR SERVICE THEY DO NOTHING FOR ME. *TR

I WAS SENT A SAFETY RECALL LETTER FROM HYUNDAI STATING THAT THE STOP LAMP SWITCH INTERMITTENTLY MALFUNCTIONS. THIS HAPPENS TO ME CONTINUOUSLY. I TOOK IT TO A REPAIR SHOP WHEN I WAS VACATIONING IN CHICAGO, AS I THOUGHT THERE WAS A PROBLEM WITH MY CAR, AND THAT I MIGHT BE IN A DANGEROUS ROAD SITUATION. THEY CHECKED IT OUT AND COULD FIND NOTHING, BUT I STILL HAD TO PAY FOR THE DIAGNOSIS. I HAVE ASKED HYUNDAI TO REIMBURSE ME FOR THIS SINCE IT TURNS OUT TO BE A MALFUNCTION, THAT CAUSED ME TO SPEND MONEY TO TRY TO DIAGNOSE. THEY REFUSE TO REIMBURSE ME, EVEN THOUGH THEY ADMIT IT IS A MALFUNCTION ON THEIR PART...BUT I WASN'T NOTIFIED OF THIS UNTIL 4 MONTHS AFTER BEING CHARGED TO TRY AND FIGURE OUT WHAT WAS GOING ON. *TR

MY 2010 HYUNDAI SONATA COMPLETELY SHUT DOWN ON ME 2-TIMES IN LESS THAN 5-MINUTES TIMES WHILE I WAS DRIVING TODAY. I WAS ON MY WAY TO ENTER THE EXPRESSWAY. THE POWER STEERING AND EVERYTHING JUST SHUT DOWN. MY CAR JUST MADE A SUDDEN STOP. THANK GOD I HAD NOT ENTERED THE EXPRESSWAY AND TOOK THE SIDE STREETS HOME. I FEEL THAT THIS IS A REAL SAFETY HAZARD TO MYSELF, THE PASSENGERS RIDING WITH ME AS WELL AS OTHER DRIVERS, PASSENGERS AND FAMILIES ON THE ROAD. MY VEHICLE HAS 53,215 MILES, THERE IS NO WAY THIS SHOULD BE HAPPENING. IF THIS IS HAPPENING TO MY VEHICLE, I KNOW IT'S OCCURRING IN OTHER SONATA'S AND OTHER HYUNDAI VEHICLES BASE ON WHAT I SEE IN ONLINE ENTRIES ON THE 2010 HYUNDAI SONATA AND HYUNDAI VEHICLES. MANUFACTURES MUST BE HELD ACCOUNTABLE FOR THE DEFECTED PRODUCTS PLACE ON THE MARKET. I KNOW THAT I'M A SMALL VOICE AGAINST A LARGE CORPORATION, BUT IF YOU TAKE THE TIME TO INVESTIGATE I KNOW THAT MY CLAIM WILL BE VALIDATED. I HOPE AND PRAY THAT SOMETHING IS DONE ABOUT THIS BEFORE WE ARE DEALING WITH INJURIES OR FATALITIES. I AM A FRUSTRATED AND UNHAPPY HYUNDAI SONATA OWNER, LOOKING FOR HYUNDAI TO PUT SAFETY FIRST! *TR

2010 HYUNDAI SONATA. 9 MONTHS OLD, HAS BEEN IN THE SERVICE CENTER 5 DIFFERENT TIMES. 2 TIMES FOR SENSOR REPLACEMENT. THE LAST 3 TIMES, DRIVING AT A NORMAL ACCELERATE PACE. CHECK ENGINE LIGHT COMES ON, ESC LIGHT COMES ON AND VEHICLE LOSES POWER. ON ONE OF THOSE OCCASIONS, VEHICLE LOST POWER WHILE GOING THROUGH INTERSECTION, AND ALMOST WAS REAR ENDED. SERVICE DEPARTMENT HAS REPLACED MANY PARTS FROM THROTTLE POSITION ASSEMBLY TO THERMOSTAT TO ELECTRICAL WIRING HARNESS. IN MY OPINION, VEHICLE IS A LEMON. *TR
