Hyundai Motor America (Hyundai) is recalling certain 2011-2014 Sonata and 2013-2014 Santa Fe Sport vehicles previously repaired under recall numbers 15V-568 and 17V-226. The high pressure fuel pipe that connects to the fuel pump outlet may have been damaged, misaligned, or improperly torqued during the engine replacement procedure, allowing fuel to leak from the pipe.
A fuel leak in the presence of an ignition source can increase the risk of a fire.
Hyundai will notify owners, and dealers will inspect and replace the fuel pipe, as necessary, free of charge. The recall began March 1, 2019. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's recall number for this recall is 180.

Exterior lighting, brake lights, switchNov 16, 2015
Hyundai Motor America (Hyundai) is recalling certain model 2011-2012 Sonata vehicles. The brake pedal stopper pad can deteriorate allowing the brake light switch plunger to remain extended when the brake pedal is released.
If the brake light switch plunger does not retract as it should when the brake pedal is not being pressed, the brake lights may stay illuminated preventing accurate communication to rearward following vehicles that the vehicle is slowing or stopping. Additionally, if the brake switch plunger is not retracted, then the transmission can be shifted out of PARK without depressing the brake pedal. Either condition increases the risk of a crash.
Hyundai will notify owners, and dealers will replace the brake pedal stopper pad with an improved part, free of charge. The recall began on January 6, 2016. Owners may contact Hyundai customer service at 1-855-671-3059. Hyundai's number for this recall is 136.

Hyundai Motor America (Hyundai) is recalling certain model year 2011-2012 Sonata vehicles manufactured December 11, 2009, to April 12, 2012 at Hyundai Motor Manufacturing Alabama and equipped with either a 2.0 liter or 2.4 liter Gasoline Direct injection engine. In the affected vehicles, metallic debris may not have been fully removed during manufacturing of the engine crankshaft. If the debris was not completely removed, oil flow may be restricted through the connecting rod bearings, causing connecting rod damage. A worn connecting rod bearing will produce a metallic, cyclic knocking noise from the engine and possible engine failure.
Engine failure would result in a vehicle stall, increasing the risk of a crash.
Hyundai will notify owners, and dealers will inspect the vehicles and replace the engine assembly, as necessary, free of charge. Additionally, Hyundai Motor America will increase the warranty for the engine sub-assembly (short block) to 10 years/120,000 miles for both original and subsequent owners of 2011 and 2012 Sonatas manufactured at Hyundai Motor Manufacturing Alabama equipped with 2.0 liter and 2.4 liter Gasoline Direct injection engines. Interim notifications were mailed to owners starting on October 8, 2015. A second notification will be mailed when parts are available.

Power train, automatic transmissionJul 18, 2014
Hyundai Motor Company (Hyundai) is recalling certain model year 2011-2014 Sonata vehicles manufactured December 11, 2009, through May 29, 2014. In the affected vehicles, the transmission shift cable may detach from from the shift lever pin.
If the transmission shift cable detaches, the transmission gear selection may not match the indicated gear and the vehicle may move in an unintended or unexpected direction, increasing the risk of a crash. Furthermore, when the driver parks the vehicle, despite selecting the 'PARK' position, the transmission may not be in 'PARK.' If the vehicle is not in the 'PARK' position and the parking brake is not applied, there is a risk the vehicle will roll away as the driver and other occupants exit the vehicle or anytime thereafter. A vehicle rollaway increases the risk of injury to exiting occupants and bystanders.
Hyundai will notify owners, and dealers will inspect and, as necessary, repair the connection between the shift cable and shift lever, free of charge. The recall began in September 2014. Owners may contact Hyundai customer service at 1-800-633-5151. Hyundai's number for this recall is 123.

Hyundai Motor Company (Hyundai) is recalling certain model year 2011 Sonata vehicles manufactured from December 11, 2009, through September 1, 2010. The affected vehicles may experience a brake fluid leak from the two brake lines that connect the brake system's master cylinder to the Hydraulic Electronic Control Unit (HECU) due to insufficient seal between the inner brake hose and metal brake line fitting.
If the brake lines leak brake sufficient fluid, the brake warning lamp in the instrument cluster will illuminate and longer stopping distance will be required, increasing the risk of a vehicle crash.
Hyundai will notify owners, and dealers will replace the brake hoses with a revised service part, free of charge. The recall began in September 2014. Owners may contact Hyundai customer service at 1-800-633-5151. Hyundai's number for this recall is 122.

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.

Engine, Sep 29, 2025
The contact owns a 2011 Hyundai Sonata. The contact stated that while driving at 55 MPH and depressing the accelerator pedal, the vehicle hesitated and stopped independently. The contact stated the vehicle went into LIMP Mode independently, with a clinking sound coming from the engine. The contact pulled into a parking lot, awaiting tow truck assistance. Neither a dealer nor an independent mechanic was contacted. The vehicle was towed to an independent mechanic, where the vehicle was inspected and the contact that the lifters needed to be replaced. The vehicle was then towed to the dealer, where it was diagnosed that the lifters, rod bearings, and piston rings needed to be replaced. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 15V568000 (ENGINE); however, the VIN was not included in the recall. The manufacturer was notified of the failure and denied the claim. The failure mileage was 167,000.
Engine, Sep 24, 2025
I own a 2011 Hyundai Sonata with a 2.0 turbocharged engine. The engine failed/presents issues such as loss of power, rattling, oil consumption, and smoking, which resulted in my engine seizing up. This creates a serious safety risk while driving, to now my car no longer operates. I checked NHTSA’s recall database and found no open recalls for my VIN regarding engine replacement, but I believe this engine defect should be investigated for a recall.
Service brakes, Sep 23, 2025
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.
Engine, Sep 22, 2025
I had just started up my vehicle as normal and exited a parking lot when all of a sudden the vehicle switched off and I was able to safely maneuver to the side of the road and it would refuse to start, and there was smoking coming from beside the engine and we were unsure of what it was. I got it towed to a local mechanic and he let me know that it was an engine failure, and that the starter had burned as result of that.
Fuel/propulsion system, Sep 17, 2025
1. The car began to randomly stall and stop running. This happened while driving and it was extremely dangerous. Typically, the engine would restart after at least waiting 15 minutes. Any attempt to start the car before that time would fail. 2. When the stalls happened, the car acted as if it had run out of gas. The engine would simply stop running WITHOUT WARNING, at intersections, on city streets, and on the freeway at high speed. It did not matter how full the gas tank was. 3. My brother and I diagnosed the problem as intermittent loss of fuel pressure. 4. My brother and I replaced the FACTORY fuel pump, and to hour horror, when we unplugged the electrical connection/plug, one of the pins from the fuel pump came out with the plug/connector. 5. We inspected the fuel pump and discovered that parts of the electrical plug INSIDE THE FUEL TANK had become burned and melted. See Image SANY0135.JPG === This is a SAFETY DEFECT - either the internal fuel pump electrical connections were faulty from the factory or the problem developed over time. There have been other recalls for this model of car for random engine stalls but this is a NEW and DIFFERENT cause. A dealer with a relatively inexpensive Infrared camera could likely spot this problem with minimal vehicle disassembly. There was clearly a LOT of heat concentrated in the area of the electrical connection to the fuel pump. We hope this report triggers a recall and prevents extremely dangerous random loss of engine power events, fires, or worse. Please recall all the vehicles that used that fuel pump for inspection before there is a disaster.

2011 Hyundai Sonata had a Theta ii engine replaced in September 2024 after engine failure. Hyundai paid for the engine through the extended warranty on the theta engines. Check engine light is still illuminated after new engine and after multiple visits to the dealership, they say the wiring harness is bad. Contacted Hyundai Corporate who said they will not pay for anymore warranty repairs, even though the wiring harness was damaged from the bad engine or during the replacement. From my understanding, it is dangerous to drive a car with a bad wiring harness due to fire risk, loss of power, or loss of safety components.

While driving our 2011 Hyundai Sonata on [XXX], my fiancée and I experienced sudden engine failure on [XXX]. The car suddenly lost power and began vibrating violently, then stalled completely and would not restart. We had to pull over in a dangerous area with no power and limited shoulder space, creating a serious safety hazard. A relative had previously scanned the vehicle and retrieved a P1326 knock sensor code, indicating a potential engine bearing issue. He cleared the code temporarily in an attempt to drive the vehicle again. However, when it failed on the freeway, we were forced to tow the vehicle twice—first to our home and then to Anaheim Hyundai for diagnosis. Hyundai later denied warranty assistance, claiming "exceptional maintenance neglect" despite the fact that we provided all available oil change records since our 2017 purchase. We were not the original owners, yet were expected to produce records dating back to 2013. No sludge or varnish evidence was cited in the repair order, and the dealer simply claimed a seized engine. We’ve since been denied under both the extended warranty and goodwill policies, even though our engine displayed the same symptoms covered in the Theta II engine class action settlement. This failure was dangerous, left us without transportation, and has caused serious financial and emotional strain. We are reporting this because it reflects a potential ongoing safety risk for other Hyundai owners. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2011 Hyundai Sonata. The contact stated that while driving at an undisclosed speed, the vehicle jerked, and the vehicle failed to accelerate as intended while depressing the accelerator pedal. The check engine warning light was illuminated. The contact stated that on a separate occasion, while driving 35 MPH, there was smoke coming from underneath the hood. The contact pulled over to the side of the road and turned off the vehicle. The contact opened the hood, and there was smoke coming from the valve cover and coolant reservoir. The contact waited for the engine to cool down and the vehicle was able to restart. The contact stated that on a separate occasion, after turning off the vehicle after arriving at work, there was an abnormal bubbling sound coming from underneath the hood. The contact opened the hood and there were bubbles coming from the radiator. Prior to the failure, the contact had replaced the radiator, due to the engine overheating. Two weeks later the radiator hose detached. The contact stated that the fluid leaking from the radiator was dark brown and seemed to be mixed with slush. The vehicle was taken to an independent mechanic who determined that there was foreign parts inside the radiator. The contact was informed that the radiator needed to be replaced. The vehicle was not repaired. A mobile mechanic arrived at the residence and confirmed that the radiator needed to be replaced and an unknown valve on top of the engine needed to be replaced. The vehicle was not repaired. The failure became progressively worse, and the vehicle was no longer driven. The manufacturer was not notified of the failure. The failure mileage was unknown.

While driving at highway speed, the engine suddenly lost power and the brakes locked. I narrowly avoided a collision. This sudden failure left me unable to safely control the vehicle, placing myself and other motorists in immediate danger. This is not only a mechanical defect but a serious safety hazard that matches the exact conditions described in Hyundai’s prior Theta II engine recalls.
Engine, Aug 6, 2025
I purchased this 2011 Hyundai Sonata (VIN: [XXX]) on [XXX]. A few weeks later, the engine started knocking, wouldn’t shift beyond 2nd gear, and wouldn’t go over 60 mph. A diagnostic test at Express Oil returned the error code P1326, which is tied to Hyundai’s Recall Campaign 132 for engine failure due to bearing wear. I brought the car to Serra Hyundai in Trussville, AL. I provided my bill of sale, diagnostic code, and a recent oil change receipt, but Hyundai denied my engine replacement, saying there was a gap in service history between 2021 and 2025 — even though I was not the owner during that time. They confirmed it was a recall-eligible engine and admitted the failure matches the recall symptoms, yet are refusing to fix it — while also suggesting I “trade the car in” instead. This is a known safety defect, and I believe Hyundai is wrongfully denying legitimate recall repairs based on ownership history rather than actual engine failure. I am now without a working vehicle. I respectfully request that NHTSA investigate Hyundai’s denial of engine replacements under Campaign 132 for new owners and hold them accountable.

To Whom It May Concern, Subject: Formal Complaint – 2011 Hyundai Sonata GLS Tail Light Meltdown / Fire Hazard Date: August 3, 2025 I am writing to formally report a serious safety issue with my 2011 Hyundai Sonata GLS, specifically concerning the tail light assembly, which has melted and poses a potential fire hazard and traffic safety risk. Approximately a year and a half ago, I noticed melting in the tail light housing and took the vehicle to a Hyundai dealership to address the issue. At that time, the car had approximately 208,000 miles. Despite the obvious manufacturing defect and safety implications, the dealership refused to repair or inspect the issue without charging a $275 inspection fee, stating the vehicle was out of warranty. I believe this to be an unfair and irresponsible business practice. Tail light assemblies should not melt under normal use, and such a defect could lead to: Electrical fires Brake light failure (increasing the risk of rear-end collisions) Potential traffic citations for inoperative brake lights Damage to other vehicles or individuals I have already notified Hyundai Motor Corporation about this issue, placing them on notice that should any damages or incidents occur as a result of this defect, they may be held liable. This is not a minor cosmetic issue but a major safety defect, and I strongly urge the NHTSA to investigate whether this is an isolated issue or part of a wider trend affecting Hyundai and Kia vehicles. If so, a safety recall may be warranted. I also intend to report this situation to the Indiana Attorney General's Office as a matter of consumer protection and product safety. I have been backwards and forwards with the Hyundai Corporation Via and Emails...... I look forward to a prompt response. Please!

My girlfriend was driving my car at 70mph on [XXX] when suddenly the engine stalled abruptly with no warning. She had to coast over to the shoulder and come to a stop. At this point the engine would NOT turn over. If it did it was very challenged to turn over as if the engine was seized-partially or fully. My car was towed to my mechanic who later confirmed that the battery and starter were indeed good and that the engine seemed partially seized and even possessed metal shavings. On top of this my car has been consuming half a quart of oil every 400 miles as I check the oil everytime I get gas. So with this information my car seems to be fit for the Hyundai class action settlement recall #132 for the 2011 Sonata GDI engine. So I towed my car to Coastal Hyundai of Melbourne, FL, a dealership where all my records and maintenance have been done and are up to date. My car has been at this dealership for TWO weeks and they won’t even confirm that they have looked at it. I am under the understanding that it is costing Hyundai a lot of money to replace this engines and that they purposely stall hoping to somehow save money. I commute 72 miles round trip to work and have been greatly inconvenienced as I am having to borrow cars from family and figure out how to get to work. Any help in this regard is greatly appreciated.
