Exterior Lighting › Brake Lights › Switch15V759000
Filed Nov 16, 2015304,900 vehiclesHyundai Motor America

Defect. 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.

Risk. 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.

Remedy. 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.

Engine15V568000
Filed Sep 10, 2015470,000 vehiclesHyundai Motor America

Defect. 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.

Risk. Engine failure would result in a vehicle stall, increasing the risk of a crash.

Remedy. 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.

Service Brakes, Hydraulic14V433000
Filed Jul 18, 2014133,075 vehiclesHyundai Motor Company

Defect. 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.

Risk. 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.

Remedy. 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.

Power Train › Automatic Transmission14V434000
Filed Jul 18, 2014883,000 vehiclesHyundai Motor Company

Defect. 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.

Risk. 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.

Remedy. 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.

Exterior Lighting › Brake Lights › Switch13V113000
Filed Apr 1, 20131,712,336 vehiclesHyundai Motor Company

Defect. 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.

Risk. 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.

Remedy. 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.

On September 24, 2026, I brought my vehicle to Kelly Hyundai Service Center for two recall repairs: IBU/BCM Anti-Theft Software Upgrade and Decal Application Anti-Theft Ignition Cylinder Protector and Decal Installation My vehicle was at the dealership all day. At the end of the day, I received a call from the technician advising me that the recall work could not be completed due to an electrical issue. When I returned home, I immediately noticed several problems that did not exist prior to the service appointment. Specifically: The high beams no longer worked. The dashboard illumination was not functioning properly. The automatic door lock system stopped working. The trunk could only be opened with the key. I contacted the service center and was informed that the only way they could determine the cause of these issues was for me to bring the vehicle back and pay a $200 diagnostic fee. I explained that I did not believe I should be charged to diagnose problems that appeared immediately after their attempted recall repair. I requested to speak with the service manager, but I was told he was unavailable. I never received a return call from management. On October 1, 2026, I returned to the service center and spoke with the manager. He recommended that I leave the vehicle for further evaluation. I did so, but later that day I received another call stating that the recall still could not be completed and that I would again need to pay a $200 diagnostic fee. I picked up my vehicle

Suspension
Filed Oct 25, 2026UT

While driving home and negotiating an ordinary turn onto our residential street, we heard a loud popping sound. We immediately pulled over and discovered that the driver’s-side rear wheel was leaning inward substantially. Upon inspecting the suspension, I discovered that the cylindrical bushing attachment on a rear suspension control arm had fractured, allowing the suspension connection to separate. I subsequently walked back to the location where the noise occurred and recovered the detached metal fragment. The fracture surfaces exhibit distinctly different coloration, suggesting that part of the fracture may have existed for some time before the final separation. Of greater concern, upon inspecting the corresponding suspension component on the passenger side, I discovered a substantial crack along what appears to be the same fracture path as the failed driver’s-side component. Both sides appear to exhibit a common structural weakness. The failure occurred during ordinary driving without a collision or known impact immediately preceding the event. A similar failure at highway speed could cause a serious crash, injury, or death. I understand Hyundai previously conducted rear lower control arm replacement Service Campaign TP3 for certain 2011–2013 Sonata vehicles. I request that NHTSA investigate whether this failure is related to a known defect or represents a broader safety concern.

My 2011 Hyundai Sonata with the 2.4L Theta II GDI engine developed an engine failure at 99,928 miles. On XXX Hyundai’s dealer (McFarland Hyundai, [XXX]) ran Hyundai’s T3G connecting-rod-bearing test, and the engine returned NO PASS. Hyundai’s own test recorded the oil level as full. This engine family is the subject of Hyundai’s connecting-rod-bearing safety campaigns and its extended engine warranty. Hyundai declined the repair (#XXX) as “exceptional maintenance neglect,” although the oil and filter were changed about 730 miles before the failure, with two more documented oil changes in the prior 16 months. Connecting-rod-bearing failure in this engine can cause engine seizure or stalling while driving, which creates a crash risk. The vehicle is at the dealer and has not been repaired. I am reporting this so NHTSA has a record of a Theta II failure in a vehicle covered by these campaigns that was denied repair.

The passenger frontal airbag deployed on its own while the vehicle was being driven, with no collision or impact that the driver is aware of. The driver airbag did not deploy. The incident occurred on October 4, 2026, at about 11:14 PM, shortly after the driver refueled at a gas station and was heading toward the highway. The airbag tore open the dashboard panel and cracked the windshield from the inside where the bag struck the glass. The driver brought the vehicle back to the gas station and it was towed. It has not been driven since. Safety risk: The sudden deployment startled the driver and the cracked windshield reduced visibility while the vehicle was moving. Anyone in the passenger seat would have been struck at close range. Recall history: This vehicle received the Recall 174 / NHTSA 18V-137 airbag control unit remedy (ACU main wiring harness installation, part 91700-4R100-QQH) at a Hyundai dealer in September 2025, at about 305,800 miles. The deployment occurred about 13 months and 18,400 miles later, at 324,243 miles. Warning signs: No airbag warning light or other warning appeared before the deployment. The vehicle was serviced at a Hyundai dealer about one month earlier (oil change and multi-point inspection), and no airbag or restraint-system problem was reported. Inspection: The vehicle is at a Hyundai dealer and is available for inspection. We have asked that the airbag control unit, airbag module, and stored crash data be preserved.

The vehicle suffered an internal connecting rod bearing failure, a known manufacturing defect affecting the Theta II GDI engine. The failure was explicitly diagnosed via the manufacturer - specific OBD-II fault code p1326 Knock Sensor Detector System. This defect causes sudden engine stalling poses an immediate risk of catastrophic engine failure or fire while driving. Hyundai Motor America has denied financial reimbursement for the required engine repair because the work was completed by an independent shop and third-party arbitration deadline (BBB Auto Line) communicated to me. The manufacturer is actively refusing to remedy an acknowledged safety defect.

Intermittent and sudden loss of power steering nearly caused an accident for both of sons when each one was driving on two separate occasions this past week. "EPS" and traction control warning lights both illuminate on the dash when steering goes out. Sometimes the codes will clear themselves out after restarting the vehicle, but not always. Had it inspected by an independent service center and they cleared out the codes with their scanner. Steering worked fine for a few days afterwards, but then suddenly lost power steering again yesterday. It is very dangerous to drive and it is very unpredictable. I see that there was a recall for this issue for certain manufacture dates for 2011 Hyundai Sonata, but mine was not part of the recall. I believe that it should be part of that recall before someone dies or is injured.

I test drove the vehicle at an auction, watched several other people test drive the vehicle. Before the auction I test drove it one more time and put my obd scan tool on it to make sure there were no hidden codes or problems. I won the bid,and picked up the vehicle. I drove it approximately 6 miles from the auction and the falshing engine light popped on. I immediately pulled over in heavy freeway traffic. Put my scan tool on it and found out the knock sensor had triggered. The vehicle was shaking and making a terrible racket. It was inoperable in the worst possible spot on Highway 51 during rush hour traffic. I managed to slowing coast down the offramp and roll into a parking lot. I then called Purdy Hyundai and spoke with a service advisor and provided the VIN#. He (Vue Kue) informed me that the vehicle qualified for the recall and warranty work based on exactly that issue. I had the vehicle towed to the Purdy dealership on July 8th 2026. I was told today that it was unlikely that Hyundai would honor the recall because I did not have service records of a vehicle I had owned for 6 miles of driving. I filed a complaint with Hyundai corporate. Claim#43010067 and awaiting the reconciliation of this situation. Of which they appear to to be avoiding.

There is white smoke coming from the left tail pipe, it is sluggish when you push on the gas, there is black soot constantly on my rims that is extreamly hard to remove, the high pressure fuel pump jas failed, I can tell because the oil is higher then it was when o had the oil freshly changed, and it smells of gasoline.inside the oil.

Just so many items consistently needing repair or replacement, even though I just had the fuel system cleaned, the oil changed, and filters, and.oil filter too.

I was heading to work when suddenly smoke started pouring from the air conditioning vents, and the ABS and traction control warning lights came on. I hit the brakes to pull over, only to realize I had lost braking power. I managed to steer to the side of the road as carefully as possible and bring the car to a stop—despite having no brakes and a fire burning under the hood. I tried downshifting to slow the vehicle, but the transmission didn't respond, and the cabin began filling with smoke. Once I stopped, there was nothing I could do to extinguish the fire, as the car was completely consumed within seconds. It was a fire in the engine bay; I lost the brakes, and the ABS and traction control lights lit up. I assume it was a critical failure in the braking system, most likely involving the ABS module.

My 2011 Hyundai Sonata (VIN [XXX] ) was brought to Gateway Hyundai in [XXX] for the mandatory P1326/KSDS engine recall inspection. I had a confirmed appointment on XXX at 7:30 AM. The dealership acknowledged the P1326 code and that the KSDS test was required.Instead of performing the recall, the dealership refused to inspect the vehicle. They contacted a third party who was not in possession of the vehicle and released the vehicle to that person without my authorization. The plates were removed and the vehicle was later sold without my consent. The recall was never performed and the engine defect was never inspected.This is a failure to perform a required safety recall and a violation of chain-of-custody procedures. A vehicle with a known engine failure risk was put back into public circulation without inspection. This creates a safety hazard for the public.I also suffered financial harm including $1,500 in towing, parts, labor, and storage fees.

On my 2011 Hyundai Sonata GLS, both rear tail lights have melted to the point that the lightbulbs cannot be extracted and the brake and tail lights no longer work. When I looked into this, I found out this is a common issue on 2011 Hyundai Sonatas. It is almost always caused by excessive heat from the standard incandescent bulbs, which damages the wiring harness and deforms the plastic housing. When I called the closest Hyundai dealer (in Chico, California), they told me the warranty had expired last year and that I should have received a notice about it after I obtained ownership of the car in March 2025 (a little over a year ago). However, I did not receive a notice about this. Since the tail lights do not work properly as a result of this problem, it is a safety issue as it could cause an accident. It should be a recall repair instead of a warranty that expires. My car is still well under the 200,000 mile limit that was set on the extended warranty, but they're refusing to honor that because of the warranty being expired.

Ourisman of Rockville and Hyundai Motor America (HMA) refuses to replace the engine for free. The vehicle has now developed a severe engine knock consistent with the well-documented defect affecting Hyundai’s Theta II engines. Hyundai has publicly acknowledged this issue and issued a major recall covering approximately 470,000 vehicles with the following specifications: • Model Years: 2011–2012 • Engines: 2.0L and 2.4L • Manufacturing Period: December 11, 2009 – April 12, 2012 Hyundai and federal regulators identified the safety concern as manufacturing debris that could restrict oil flow to rod bearings. This defect can lead to engine knocking and eventual engine failure. Critically, Hyundai has acknowledged that engine failure may stall the vehicle while driving, significantly increasing the risk of a crash. Hyundai’s official remedy for this defect required dealerships to: • Inspect engines for bearing noise • Replace the engine if necessary • Honor Hyundai’s extended engine warranty of 10 years / 120,000 miles for affected vehicles.

The contact was able to drive the vehicle to a nearby residence, where it temporarily remained. The contact attempted to drive the vehicle a few miles to qualify for towing, per the vehicle insurance provider. The vehicle was towed to a local dealer, where it was diagnosed with a rod bearing failure. The vehicle was not repaired due to insufficient engine oil maintenance records.

Service Brakes
Filed Nov 19, 2025VA

The vehicle experiences a recurring defect where the brake light turns on suddenly and the engine shuts off while driving. The failure appears related to the braking system (brake switch circuit), electrical system (CAN-bus/ECU communication), and engine control (shutdown/stall). The system remains installed and is available for inspection upon request. The shutdown poses a serious safety risk, including possible rear-end collision or loss of power in traffic. The problem has occurred multiple times. The dealership inspected the vehicle briefly but failed to diagnose or document the defect and returned the vehicle within hours, stating “it shouldn’t be a problem,” even though the issue continues. Hyundai has refused to provide recall documentation or authorize a re-inspection. The only warnings prior to shutoff are the sudden activation of the brake warning light just before the engine cuts off.

While driving home from work after 7 PM on the 215 NB freeway, the oil warning light suddenly illuminated, and the vehicle immediately lost engine power. Within seconds, the engine shut off completely, leaving me unable to accelerate or safely maneuver. I was forced to coast across lanes with no power, creating a significant risk of collision and nearly resulting in a rear-end accident. After the incident, I performed a crankshaft rotation test, which the engine failed, confirming that the crankshaft would not turn. I also verified that the timing chain remained intact. The vehicle has since been inspected by Hyundai technicians, who confirmed the engine failure under Service Campaign 953. Hyundai further communicated via email that my vehicle is eligible under the TXXI Theta Engine Settlement Agreement and expressed a willingness to discuss my recent engine concerns and the details of the settlement.

I am filing this complaint regarding a catastrophic engine failure in my 2011 Hyundai Sonata. According to Hyundai’s own documentation, Service Campaign 953, issued in 2018, was never performed on this vehicle. This campaign addresses the risk of connecting rod bearing failure caused by residual metal debris in the crankshaft oil passages.

Good day, please note that most of my communication with Hyundai has been over the phone. I sent one an email shortly after the event, and after following up on the phone, I received this following string separately. I can forward you more along the way, but Hyundai is in possession of the call recordings. I was hoping they would cover my repairs, my engine had a lifetime warranty, but during this process I learned that there was a recall for this car that I was never aware of as the new owner. I needed a software update to get any repairs covered. Please reach out to me for more info!

In summer of 2023 my car 2011 Sonata Hybrid quit running and would not start. My granddaughter had used the car to go to Oklahoma City for a tennis tournament. Her life was at risk because she was coming back in the evening and was alone. The next day I had the car towed to Ada Oklahoma and then called dealership and had it towed to Ardmore, Oklahoma where I had purchased the car new in 2011. The car was at the dealership for 6 months. The vehicle was inspected at the dealership. There were no warning lights or symptoms of the failure prior to the breakdown. I am an 80 year old female that knows nothing about a car engine and they talked to me like I was a mechanic. I still do not know why my claim was denied but was told that I did not have a claim. I had to rent a car to get to work for several months and was out the money to have my car towed 2 times. Not to mention the strain of being without my car for 6-7 months. I finally just gave up until I read about all these other people having trouble with Hyundai also.

I bought this car from someone in April of 2024 and the person who i bought it from said everything was perfectly fine, they brought it to the Hyundai dealership and according to the mechanic there the engine was fine….i have taken care of the engine since i bought the car, kept up with oil changes and everything….until a few days ago when the whole thing ceased up on me while driving down the road to my sons school. I wasnt going fast either, the speed limit is 40mph where i was when it happened, but I’m glad i have quick reflexes because otherwise we would have wrecked the car. Everything shut off on me and now its knocking. There is alot of metal shavings in my oil and my mechanic tried to drain it a few times to get the debris out of the oil but it does no good.

My daughter was driving her 2011 Hyundai Sonata on the freeway at 65mph when the engine light came on and car simultaneously slowed to a stop on 8/21/25 creating significant danger to my daughter and other drivers on the road. There were no prior warnings or indications, and car just had an engine check performed in June 2025. Had it towed to Hyundai on 8/22/25 and Hyundai completed an engine check and it failed. Hyundai told us they'd cover it under the extended warranty if only we could provide complete maintenance records. We were unable to satisfy their record request threshold, as we are not the only owners of this 14-year-old vehicle, so they've requested $10,000 to replace the engine instead. The 2011 Hyundai Sonata is part of the Theta II engine family that has been subject to multiple recalls, class-action lawsuits, and federal investigations due to catastrophic engine failures.

Reading this record

3 deaths reported in complaints filed with NHTSA.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
