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.

Seat belts, pretensionerFeb 27, 2018
Hyundai Motor America (Hyundai) is recalling certain 2011-2013 Sonata and 2011-2012 Sonata Hybrid vehicles. On February 27, 2018, Hyundai Motor Company (Hyundai) notified NHTSA that they were recalling 154,753 model year 2011 Sonata vehicles.

In the event of a crash, the air bag control unit (ACU) may short circuit, preventing the frontal air bags, seat belt pretensioners, and side air bags from deploying.
If the frontal air bags, seat belt pretensioners, and side air bags are disabled, there is an increased risk of injury to the vehicle occupants in the event of a vehicle crash that necessitates deployment of these safety systems.
Hyundai will notify owners, and dealers will install an external wire filter kit, free of charge. The recall began October 15, 2018. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 174.

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. Owners may contact Hyundai customer service at 1-855-671-3059 or by visiting www.HyundaiUSA.com/Campaign132. Hyundai's number for this recall is 132.

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 is recalling certain model year 2012-2013 Hyundai Sonata passenger cars, manufactured from January 24, 2012, through June 21, 2012. The curtain side airbags on these vehicles may inflate without deployment command due to an error during manufacturing.
The curtain airbag may inflate without deployment command and increase the risk of injury to occupants of the vehicle. Additionally, an unexpected deployment would be a significant driver distraction and would limit the driver's visibility, increasing the risk of a crash.
Hyundai dealers will notify owners, and dealers will replace the curtain side airbags free of charge. This recall began on August 31, 2012. Owners may contact Hyundai at 1-800-633-5151.

Based on what I experienced, the fire appears to have resulted from an internal mechanical or electrical failure that occurred without warning while the vehicle was in motion. No prior issues or dashboard alerts were present at the time, and there was no external impact or damage that could explain the fire.

On [XXX] while driving approximately 1.5 hours away from home, a warning message appeared on my dashboard stating: “Hybrid System Warning. Stop and Do Not Drive.” I immediately pulled over and contacted my insurance company, who arranged for the vehicle to be towed to the nearest authorized Hyundai dealership (Thomas Hyundai in Cumberland). The warning clearly indicated that it was not safe to continue driving. Later, I found out that the issue reported (recall 198) have presented cases ending with fire of the engine. It is critical to mention that in January 2025, I attended the official manufacturer recall for this vehicle, which was supposed to ensure safety and reliability. Despite this, the vehicle failed and left me stranded in an unsafe area. Since then, I have been without my vehicle for over three weeks. I contacted Hyundai customer care and opened a case. I was repeatedly told a case manager would call me within three business days, but I never received any follow-up until I insisted. I was eventually assigned a case manager named Snowy, and also remained in contact with the dealership. On several occasions, both Snowy and the dealership assured me that the vehicle would be ready by Thursday, July 10 and that It was not until then that I could start to request a reimbursement for my rental expenses. I repeatedly asked for confirmation because I am renting a car at my own expense in order to go to work and manage my life. However, on Thursday, July 10, I called again and was told the vehicle would instead be ready by Tuesday, July 15. Then, on Friday, July 11, I received an email stating that the engine had just arrived, and that the dealership was only now able to begin repairs. After that, and only once the car is finished, Hyundai will “review” the case and determine whether I qualify for reimbursement. This is unacceptable. I have been without a vehicle for over three weeks, forced to rent a car entirely at my own expense. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I drive a 2012 Hyundai Sonata Limited. After a recent fill-up, I began experiencing delayed acceleration, engine hesitation, and what appears to be misfiring—especially at low throttle. Most notably, the brake lights stay illuminated even when the car is turned off, which drains the battery and poses a major safety hazard. I scanned the vehicle with an OBD-II scanner and received code P0504, which points to a brake light switch malfunction. I also noticed that pressing the start button with my foot off the brake still starts the engine instead of going into accessory mode—confirming abnormal brake signal behavior. I replaced the brake light switch, which temporarily fixed the issue, but the symptoms returned within a day. After researching, I found there was a recall (NHTSA 15V759000) for a nearly identical issue involving the brake light switch and stopper pad. However, my VIN is not listed, even though I am experiencing the same safety-critical symptoms. This issue poses a significant safety risk on the road, and I believe my vehicle should be included in the affected population of the recall or issued a Technical Service Bulletin extension.

On [XXX] at approximately [XXX], my [XXX] Daughter was using my car to go to work. When she called us and informed my husband that the car did not start. At that point he asked to video call him so that he can visually see what was going on. She was directed to turn on the car again at and that point, the car started then smoke was noticed from coming out of the hood. My daughter managed to open the hood where flames emerged from the center of the engine. She then ran in the house to get a fire extinguisher and managed to put it out and it reignited. She then made a second attempt with another fire extinguisher where it briefly subsided and then grew larger. At that point the fire dept arrived and successfully extinguished the fire and deemed the car totaled after the Fire Marshall carefully inspected the car.

I’ve been having issues with my Gas Gauge not recognizing how much gas I have in my car. I can fill my tank up, and the gas light constantly stays on. I’ve been looking online and came across other Hyundai owners having the same problem. I also have been having what seems to be an electrical issue where my passenger door, does not open and it’s intermittent which also seems to be connected to why my car ceiling light won’t turn on all the time. Lastly, I have to constantly change the head light bulbs and the break light bulb. I’ve owned my car for 3 1/2 years now, and I shouldn’t have to keep having to put money into it when it seems to be a known issue.

The contact owned a 2012 Hyundai Sonata. The contact stated that various functions on the steering wheel including the horn, cruise control, and other electrical functions; all failed to operate as needed. The vehicle was taken to an independent mechanic where the contact was informed that a warranty had been placed on the vehicle for the clock spring which they linked to the failure. The steering wheel also began to stick soon after the diagnosis. The dealer was notified of the failure; however, the dealer could not provide an appointment until months out. The contact then stated that while driving at 65 MPH, the vehicle began to hesitate upon the depression of the accelerator pedal. The contact began to pull over as the EPS(Electrical Power Steering) and several other warning lights appeared on the instrument panel. As the contact opened the door, a fellow motorist had also pulled over to alert the contact that the vehicle was on fire. Soon after exiting the vehicle, the entire vehicle quickly became engulfed in flames. The fire department quickly arrived on the scene and extinguished the fire. The contact was not injured, no other occupants were inside the vehicle, and the contact was unsure if a fire or police report was filed. Some of the grass and trees in the area had caught fire as a result of the failure. The remains of the vehicle was towed to an independent tow yard. The dealer nor the manufacturer had yet to be notified of the failure. The vehicle was completely destroyed. The failure mileage was approximately 125,000.

My brake lights are constantly needing replaced. Sometimes they stay on even when I'm not braking, other times they won't come on at all when I brake.

The rear tail lights repeatedly "burn out" and have to be replaced. This endangers me and other drivers when the tail lights are not working. The police have told me to fix it. I took it to the dealer who said it will cost $900 to replace wiring. Hyundai has issued an extended warranty (no recall) for this problem but will only fix it if the wires have melted. I believe this is manufacturer defect that they should repair.

•brake failure •this has happened at indiscriminate times including the highway, suddenly the car tells me to stop driving and the brakes don’t work as they should, no telling this would happen until it occurs. When pressing brakes, a loud noise rumbles through the car and I am no longer able to drive at any speed higher than 5 mph (an issue for being on the road) risk of possible collision as this happens suddenly and gives short time to take action •UKNOWN •was inspected by local dealer, they said it was the primary pressure sensor which is a part of the Hydraulic brake booster pump. They wanted to replace the entire hydraulic unit even though it was only the sensor that was faulty and it would cost me $3,503.61 which is an ABSURD price for an electrical issue that I did not see coming at all and it is a robbery of regular people who need their cars to get to the places they need to be (work and family) this is NOT a luxury, I need my car •no warning signs or lights until the issue actually occurred. The only light that showed was the ABS lights, maybe it’s linked to the recall about the brake fluid leaking causing fires?
