2012 Hyundai Sonata

Defect. 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.

Risk. A fuel leak in the presence of an ignition source can increase the risk of a fire.

Remedy. 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.

Defect. 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. On April 18, 2018, Hyundai expanded the recall to include an additional 425,305 model year 2012-2013 Sonata and 2011-2012 Sonata Hybrid 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.

Risk. 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.

Remedy. 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.

Defect. Hyundai Motor America (Hyundai) is recalling certain 2011-2014 Sonata and 2011-2015 Sonata Hybrid vehicles previously repaired under recall campaign 17V-152. The seat belt linkages for both front seat belts may detach from the seat belt anchor pretensioners.

Risk. If the seat belt linkage detaches from the seat belt anchorage, it can not properly restrain the occupant in the event of a crash, increasing the risk of injury.

Remedy. Hyundai will notify owners, and dealers will again verify the connection between the seat belt linkage and the pretensioner and additionally install a warning label to prevent future seat belt linkage detachment, free of charge. The recall began November 6, 2017. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 169.

Defect. Hyundai Motor America (Hyundai) is recalling certain 2011-2014 Sonata and 2011-2015 Sonata Hybrid vehicles. In the affected vehicles, the seat belt linkages for both front seat belts may detach from the seat belt anchor pretensioners.

Risk. In the event of a crash, if the seat belts detach from the anchor pretensioners, it can increase the risk of injury.

Remedy. Hyundai will notify owners and dealers will inspect the connection between the seat belt linkages and the seat belt anchor pretensioners, repairing them as necessary, free of charge. The recall is expected to begin April 7, 2017. Owner's may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for the recall is 160.

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.

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. 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.

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.

Defect. 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.

Risk. 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.

Remedy. 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.

On August 19, 2026, at 76,170 miles, the engine in a 2012 Hyundai Sonata GLS suddenly lost power and shut off while the vehicle was moving on gas station property. The driver had traveled approximately 10 feet before the engine stopped. Repeated attempts to restart were unsuccessful; the engine would not crank. The driver shifted into neutral and pushed the vehicle to a safe location. Before the failure, the vehicle was running smoothly, with no warning lights, warning messages, unusual noises, or other symptoms. There was no collision, injury, smoke, or fire. The sudden, unannounced loss of propulsion created a safety concern because the vehicle could no longer move under its own power. Fortunately, the driver was still on the gas station property and was not blocking traffic. An independent repair shop inspected the vehicle and confirmed that the engine was mechanically locked up. The vehicle was subsequently taken to an authorized Hyundai dealership for inspection. The dealership’s service adviser reported lower rod-bearing failure. Hyundai later denied engine-replacement coverage, citing neglect and missing maintenance records. That denial is being disputed through BBB arbitration. The vehicle had received an oil and filter change and a mechanical inspection on August 4, 2026, at 74,548 miles—15 days and 1,622 miles before the failure. The vehicle remains at the Hyundai dealership, and the engine is available for inspection upon request. The exact underlying cause of the

I am reporting a total manufacturer parts shortage. My 2012 Hyundai Sonata GLS is part of the Hyundai Anti-Theft Customer Satisfaction Campaign P33 (Ignition Cylinder Protector). Hyundai launched this program to fix a massive vehicle theft vulnerability, but they have failed to release or distribute the physical parts to dealerships. I have been blocked from receiving this security fix since the campaign's rollout, leaving my car exposed to theft. I spoke today 10/15/26, with Piazza Hyundai in West Chester PA, to schedule appt, and was told this recall was launched in 12/25, and as of today, Hyundai still has not provided the parts. The P33 letter mandates that I repair the car by March 31,2027. BUT THERE ARE NO PARTS!

The passenger side curtain and front airbags popped with no crash or reason, yes Hyundai will be able to inspect upon pick up. My safety risk was fortunately at minimal during times of explosion because I had just parked the vehicle when curtain side air bags went off first then slowly reserving when the front passenger side air bags went off good thing I wasn’t on highway going highway speeds. The manufacturer said some one will reach out to me in 2 business days. No there were no warnings lights or anything

The contact owns a 2012 Hyundai Sonata. The contact stated that while driving at 30 MPH, the check engine warning light illuminated, the engine started knocking, and smoke emitted from under the hood. The contact decelerated to approximately 15 MPH and drove to her nearby residence. Upon inspection, the contact observed green fluid under the hood. The vehicle was towed to an independent mechanic, where it was diagnosed that the engine had failed and the head gasket was blown. The mechanic informed the contact that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 100,000.

Vehicle engine caught fire in April 2026! Tow company sold for parts without my permission! Immediately after gaining possession of my car. I didn't have comprehensive insurance, only basic. I had a brain bleed stroke Nov. 2022 and this is causing stress, setbacks. No attorneys want to take the case because there was no injuries! I jumped out in time. THANK GOD!

Diagnosed 07/20/2026 with catastrophic oil ring failure requiring engine replacement. Engine can stall due to oil degradation/absence of causing uncontrolled vehicle handling and fire. This would put myself and others at risk. It has been diagnosed at dealership. Complaint Narrative: The subject vehicle is experiencing its third total engine failure due to an inherent manufacturing and design defect, presenting a severe and repeating highway safety hazard. The original factory engine failed catastrophically in 2015 at 116,440 miles and was replaced under NHTSA Recall 15V-568. The second engine failed in 2021 at 244,710 miles and was replaced under NHTSA Recall 17V-226. The third engine (the second replacement) has now failed prematurely at 334,935 chassis miles, lasting a mere 90,225 miles. An authorized Hyundai dealership diagnosed a total failure of the oil control rings. This mechanical defect allows engine oil to bypass the pistons directly into the combustion chambers. This causes severe, rapid oil consumption, spark plug fouling, engine stalling, and total loss of motive power at highway speeds without prior dashboard warning illumination. The manufacturer is failing to provide safe, durable remedies for its federally mandated safety recalls (see warranty info Magnuson-Moss Warranty Act (15 U.S.C. § 2301 et seq./ Breach of Implied Warranty of Merchantability). Instead, they are installing subsequent replacement powerplants that suffer from the exact same structural vuln

As I was merging onto the interstate I put my foot on the gas pedal to give it a little more gas then usual to get pulled out and all of a sudden all the lights on the dash board illuminated and it slowly lost all power I was able to move it out of the road ... There was no loud ,knocking or ticking noises prior to this happening there was no type of any kind of warning .. my car is the push start button so after the car died completely I hit the push button and all the lights on the dash came on the radio worked and everything else seemed to be working it was when I went to put my foot on the brake to start it it would do nothing it would not start at all .. I was still able to put it in neutral even after the incident happened . I had it towed t Hyundai of Bristol to have it inspected well they did verifi that the engine was locked up but failed to give me any information on the test they ran or how they keep it was locked up and what locked it up so then they have my car over a week and they tell me I need a new engine but then contact me to tell ke that HMA refused to replace the engine on warranty and I had the campaign 953 completed the knox sensor thing before my car broke down so then I had to pay for towing once again out of my pocket to go pick the car from their dealership so when I got there to get my car the service was not that great and my car was in a mess very uncalled for the battery to the car was completely dead with that being said we had to use another b

Around the end of May 2026, my vehicle stalled without warning while traveling at highway speed. The engine light and EPS warning light illuminated simultaneously. The engine cranks but will not start. The vehicle was towed to a Hyundai dealership on June 15, 2026 where the engine failure was confirmed. My safety was directly at risk. The vehicle lost power on an active highway with no warning, creating a collision hazard for myself and other drivers. The failure has been confirmed by the dealership. Hyundai Motor America acknowledged the engine failure falls under the TXXI Settlement Agreement and offered a buyback or cash settlement. However, Hyundai has had physical possession of my vehicle since June 15, 2026 and has repeatedly failed to provide a written buyback offer despite multiple commitments to do so. Prior warning signs included the engine and EPS lights activating at the moment of failure. No prior warning lamps appeared before that day. The vehicle has 2 open safety recalls as of the date of purchase in November 2025.

The contact owns a 2012 Hyundai Sonata. The contact stated that while driving at an undisclosed speed, there was an abnormal burning odor coming from the vehicle. While depressing the accelerator pedal, the vehicle hesitated and stalled. The contact stated that the rear driver’s side brake light was inoperative. The failure occurred on several occasions. No warning lights were illuminated. The contact researched and was made aware of an undisclosed recall; however, the VIN was not included in the recall. The vehicle was taken back to the residence. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 168,000.

I am reporting a pattern of systemic failures on a 2012 Hyundai Sonata Hybrid with approximately 131,000 miles. This is my second NHTSA complaint regarding this vehicle and manufacturer. Primary Safety Concern — Engine Wiring Harness: During a recent engine replacement at an authorized Hyundai dealership, technicians identified damage to the engine wiring harness and documented in writing that the owner “might have issues with drive ability.” The dealership declined to repair it under the same goodwill program used to replace the engine and returned the vehicle with this known defect unresolved. The harness directly controls engine operation, hybrid system communication, and overall vehicle control. On a hybrid vehicle, a compromised harness presents a serious and ongoing safety risk. This component is available for inspection upon request. Engine Failure: The hybrid system warning light appeared prior to failure. The vehicle was towed to an authorized dealership where diagnostic code P1326 confirmed engine failure. The manufacturer acknowledged this and replaced the engine under goodwill. Additional System Failures: A pre-scan diagnostic revealed simultaneous fault codes across six systems — engine, transmission, ABS, active hydraulic booster, battery management, and motor control unit — including codes U0293 and U1004 indicating lost communication with the hybrid powertrain control module across multiple systems simultaneously. Independent Safety Advisory: A separate indepe

The contact owns a 2012 Hyundai Sonata. The contact stated that while driving at an undisclosed speed, the driver’s side seat belt unexpectedly detached. Several attempts were needed to secure the seat belt while driving. The contact stated that while the vehicle was parked, the driver’s seat belt became inoperable and failed to latch properly. An independent mechanic was contacted. The vehicle was not diagnosed or repaired. The dealer was also contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 127,819.

Vehicle: 2012 Hyundai Sonata Incident Date: August 14, 2024 Location: [XXX] Description of the Problem: The vehicle experienced a sudden and catastrophic fire without warning while in normal use. There were no prior warning lights, messages, or symptoms before the incident. The failure appears to have originated from the electrical system and/or engine (exact cause UNKNOWN), which resulted in the vehicle igniting unexpectedly. Safety Risk: This failure created an immediate and life-threatening safety hazard to all occupants. The vehicle caught fire suddenly, leaving no time to react or prevent injury. There was no crash or external cause associated with this fire. The incident required emergency response from Butts County Fire and Emergency Services, who generated an official report. Injuries and Trauma: My son suffered burn injuries to his fingers, requiring emergency medical treatment. There is neurological damage to the fingertips, indicating lasting physical injury. In addition, my son experienced significant psychological trauma due to sudden exposure to a life-threatening vehicle fire, including acute emotional distress during the incident and ongoing fear associated with vehicle safety. This demonstrates the extreme danger posed by a sudden, unpreventable vehicle fire. Inspection / Confirmation: The incident was documented by Butts County Fire and Emergency Services. At this time, manufacturer inspection is UNKNOWN, dealer inspection is UNKNOWN, and insurance inspectio

I purchased a used 2012 Hyundai Sonata. Within about 2 weeks it broke down while I was in the far left lane of the freeway. The car suddenly stopped accelerating and made a very loud knocking noise. Thankfully I was able to put on my hazards and make it to the right shoulder without getting into an accident but as soon as I pulled over it shut off and the panel lights all came on. Evidently there was a recall on an engine rod and the previous owners advised they were not aware of it. Hyundai has declined the repair on the recalled engine several times and their reasons keep changing. First they said I was missing records (admittedly I was missing one record but then provided it to them), then they stated excessive neglect due to the condition of the valve train (I saw pics of the valve train and is in good condition), and now they state because the KSDS wasn't installed. From what I understand, being the second owner, if I can prove the upkeep of the vehicle the extended waranty should cover the repair. I even have the letter from the car mechanic stating the vehicle was maintained and in good condition. It seems a lot of good people are getting declined for repairs on these faulty engines. I have many more documents I could provide showing all of the services done and communications with the company. Due to the size limit I included these ones for your review. Thank you so much for any help you can provide.

The airbag warning light came on, so we took it in to see about a recall on the airbag control unit issue that required a wire filter kit as out lined in a recall in 2011-2013 Sonatas and Sonata Hybrids. In fact, upon reading the invoice filling out this form, I think that is exactly the issue, and Potamkin Hyundai is ignoring the recall. The invoice states that "AIRBAG MODULE NEED FIXING caused by the DTC for the driver airbag resistance is too high, and has liquid leaking out of it through the connector into the clock spring, and need to replace the air bag incongruent with clock spring to perform repair correctly" The technician explained to my son that driving the car in it's current state, the air bag could go off at any moment, possibly killing him. Their airbag could kill my child. The repair is quoted at $1588 and the solution was to turn off the airbag until a decision could be made if my son wanted to drive the car home, which he did, so not it is disabled. It is a Hyundai manufactured airbag, a safety feature installed into this vehicle that should not degrade over time. It is actually the reason my aunt bought the car for her child and why my son bought the car from her. The car has never been wrecked, the airbag had never been deployed or otherwise molested, has been dealer maintained, and had an extended warranty. I spoke to a Hyundai representative and am awaiting a call back, I do not think that he should be responsible for repair of a defective, degrading saf

While driving, the vehicle experienced sudden engine malfunction. The car entered limp mode, lost power, and produced a loud knocking noise from the engine. The failure occurred without warning and created a safety risk because the vehicle could not accelerate properly in traffic. This increased the risk of being rear-ended or unable to move out of dangerous situations. The issue appears to involve the engine (possible internal failure). The vehicle is currently at an authorized dealership and is available for inspection upon request. The problem has been confirmed by the dealership during inspection. The vehicle has been under diagnosis for over three weeks. There were no prior major warning signs before the failure. At the time of the incident, the vehicle suddenly lost performance, entered limp mode, and began making abnormal engine noise. This issue is consistent with widely reported engine defects in similar vehicles. Despite this, the manufacturer has denied coverage and attributed the issue to maintenance, even though regular maintenance was performed. This is a serious safety concern due to sudden loss of power while driving.

While I was driving my car wouldn’t go no higher than 60mph and kept dropping speed but I came to a stop and when I stopped the car was smoking. I heard knocking noise and rumbling noise on the passenger side. It wouldn’t start again

Painting chipping on front top car... Seatbelt don't fasten all the time...Lights are dim.

Odometer Fraud. The contact purchased a 2012 Hyundai Sonata. It was discovered that there was a mileage discrepancy after the purchase. The vehicle was a private sale. The contact stated that the mileage on the title was discovered to be 98,000. At the time of purchase, the vehicle mileage was 99,000; however, a Carfax Report indicated that the mileage was 237,532.

My 2012 Hyundai Sonata recently had an engine replacement completed under a Hyundai recall. Immediately after the recall repair, the vehicle began shaking while driving, produced a burning smell, and the air conditioning stopped working, none of which occurred prior to the recall repair. These symptoms started immediately after the engine replacement, indicating a possible improper or unsafe installation. I believe the vehicle is unsafe to drive due to the burning smell and shaking. I contacted Hyundai Customer Service and was told the issue must be resolved with the dealership. However, the dealership has refused timely inspection, has dismissed my safety concerns, and has declined to provide a rental or loaner vehicle, leaving me without safe transportation. This is a post-recall safety issue, and I am concerned about the risk of fire or mechanical failure due to the burning smell and vehicle instability. I am requesting this issue be formally investigated.

The contact owns a 2012 Hyundai Sonata. The contact stated while driving 70 MPH, the check brake and "Hybrid System Warning Safely Stop - Do Not Drive" messages were displayed on the instrument panel, and the vehicle went into LIMP Mode. The vehicle was towed to the residence, and the contact replaced the hydraulic pressure units and hydraulic unit assemblies (HECU/ABS modules). The contact stated that after the repairs, the failure returned approximately 30,000 miles later. The dealer was notified of the failure, and the contact was provided with an estimate for the repair. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 130,000.

The contact owns a 2012 Hyundai Sonata. The contact stated that the vehicle was experiencing excessive oil consumption, which required the oil reservoir to be refilled after 3-4 weeks. Additionally, there was no warning light illuminated. The contact stated that upon taking the vehicle to Jiffy Lube for a top off, the mechanic would inform the contact that the oil reservoir was empty and needed to be refilled. The vehicle was not taken to the dealer. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 158,000.

The vehicle dashboard is severely cracked. It doesn’t appear to be from wear and tear.

The contact owned a 2012 Hyundai Sonata. The contact stated that while driving to her residence at unknown speeds, the vehicle suddenly caught fire while making a U-turn. The brakes and emergency brake were inoperable. The seatbelt was inoperable. The driver jumped out of the window. A pedestrian attempted to alert her of the fire. The vehicle exploded after exiting the vehicle. The contact sustained an injury to her leg, but no medical attention was provided. The fire department extinguished the fire. A police report was filed. There was no report of a crash or airbag deployment. The vehicle was towed to a tow lot. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 136,000. The vehicle was auctioned off by the towing company.

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.

Noticed there’s a crack on the passenger side dashboard of the car that’s about 12 inches long. From what I read this could cause issues with any possible airbag deployment.

The engine in my Hyundai Sonata (replacement engine VIN [XXX] ) experienced a complete internal failure. The component that failed is the 2.4L Theta II GDI engine, which is known for issues related to metal debris, oil restriction, rod bearing wear, and resulting piston and compression failure. The failed engine is currently at the dealership (Carolina Hyundai) and is available for inspection upon request. My safety was put at risk because the engine lost power unexpectedly, ran extremely rough, and became inoperable. A sudden loss of power while driving could have caused a crash, especially in traffic situations. The problem has been reproduced and confirmed by the dealership. They performed a compression test and found all cylinders at extremely low PSI (35–45 psi). The dealer stated the engine cannot perform the required bearing clearance test due to the level of internal damage. Hyundai Corporate initially declined assistance, calling it a piston failure, but the symptoms and damage are consistent with the known Theta II recall issues. The vehicle has been inspected by the dealership, and all diagnostic information has been submitted to Hyundai under PA Reference #XXX. Hyundai Corporate has not yet responded to me with a case manager. Before the engine failure, the vehicle had rough running and loss of power, but no warning lights or messages illuminated on the dashboard. Symptoms appeared shortly before the engine became undriveable. Based on the dealer’s findings and th

My 2012 Hyundai Sonata (VIN: [XXX] ) experienced complete engine failure at 241,433 miles on August 7, 2025. The failure aligns with known safety defect symptoms described under NHTSA Recall Campaign 15V568000 and 17V226000, which cite premature bearing wear due to metal debris during engine manufacturing. My vehicle had previously received the knock sensor update under Campaign T3G and failed the BCT (bearing clearance test), confirming bearing damage. Despite this, Hyundai denied my engine replacement claim, stating the issue was related to a fuel pipe and not a rod bearing issue—this is contrary to their own recall documentation and dealer diagnosis. Hyundai continues to deny engine replacement, in violation of their federal recall obligations under 49 U.S.C. §30120. Their refusal endangers public safety by ignoring engine failures that can lead to stalling and crashes. I request NHTSA intervention to compel Hyundai Motor America to comply with federal law and perform the necessary recall repairs on my vehicle.

My 2012 Hyundai Sonata cut off and stopped working! The vehicle locked up in the middle of a main street and would not start back up causing a very unsafe situation. There were no check engine lights on or anything at the time of the incident I immediately had the vehicle towed and inspected it has been determined that the engine is failing! Upon research I found out that these engines have had recalls in the past. Carfax shows that the vehicle has been taken in for routine maintenance and oil changes when needed. I am looking to see if the engine replacement could be covered for this vehicle.

My engine seized on the highway on my way home from work. The service department has been horrid. They lied about who the manager is. They lied about the reason behind not wanting to honor the recall. They are rude - threatened to tow my car today after I waited 6 days to hear back from them about the issue with my car and determination. Was extremely rude. Stated that they were not honoring the recall because there was obvious signs of my engine being tampered with or certain parts on my engine, but could not provide a name of the part or a serial or model number so that this could be verified. I need this addressed immediately.

No incident to report. Vehicle not regularly driven in about 5 years, other than to keep battery charged. But charge not hold. Have to charge battery again the next day. This is to reporting a crack in the passenger side dashboard where airbag is located.

This is the 2nd Hyundai I've owned, same year make and model. The first one was totaled due to the air bag deployment. The accident did not warrant the air bag deploying. I should have reported it at the time. I didn't realize that I could and now it's too late. The claim has already been submitted. Now, we have the same exact car and a crack has appeared on the passenger dash. My concern is the airbag. The crack just appeared from nowhere. I do not feel that we should have to pay for a replacement dash. Is this something that can be repaired by Hyundai, as it poses a risk to my 18 year old student driver.

My car has a problem whith the break lamps, the sockets that hold the bulbs are melting and they have deformed making it hard to replace the fused bulbs. Also the brake light stay on even after the engine is off draining the Battery and causing a short circuit.

Vehicle loses power while driving making it unsafe to drive, it can cause an accident in certain conditions like when passing another vehicle or crossing a street. There is a recall for this issue.

Driving came to a stop ,light turned green made a U-turn to go to the gas station heard a pop noise smoke came from inside the car tried stopping it but the brake pedal sunk into the ground pressed my emergency brake it was seized wouldn’t go down (never had that issue my brakes always work ) I smelled brake fluid and seen the abs light on the dash then the power started to go out and my girlfriend almost got trapped in the car

The contact owns a 2012 Hyundai Sonata. The contact received notification of NHTSA Campaign Number: 18V934000 (Engine, Fuel System, Gasoline). The contact stated that while driving 20 MPH, the vehicle stalled. There was an abnormal knocking sound coming from the vehicle. While driving at an undisclosed speed, the vehicle stalled after five minutes. The engine and the ABS warning lights were illuminated. The vehicle was towed to the residence. The contact called the local dealer and was informed that the maintenance records were needed. The contact was using an independent mechanic for maintenance and did not have the records. The vehicle was not diagnosed or repaired. The manufacturer was contacted and opened a case. The failure mileage was approximately 100,000.

Came off the highway to a stop sign went turn and the engine just seized and would not start no matter what I did. had to have it towed to my house. safety risk was just off the road so i did not get hit. police stop and told me to get a tow truck. and no warning signs at all

The part of hand break assembly that’s inside the disk break (the drum assembly) fell off when the dealer ( [XXX] Hyundai, Schaumburg, IL) tried to adjusted. I went to the dealer because the hand break stop to function. I suspect very bad design of the whole assembly disk and drum break. Also the dealer stated that all assembly was rusted.

My 2012 Hyundai Sonata originally had its engine replaced under Hyundai’s recall (NHTSA Recall #17V226000) due to the Theta II GDI engine defect. The replacement engine was installed by the dealership as part of the recall. However, the replacement engine has now failed after only ~50,000 miles, exhibiting the same issues (engine knocking, stalling, and eventual failure). This occurred despite proper maintenance and care. The dealership contacted Hyundai, and I also contacted Hyundai Consumer Affairs directly. Both refused to replace or assist with the failed replacement engine. It is unacceptable that a recall replacement engine would fail so soon and that Hyundai will not stand behind the part they used to correct a safety defect. The issue remains a serious safety concern, especially since engine failure can lead to fire. I request that NHTSA investigate the durability and safety of replacement engines and Hyundai’s refusal to support affected owners when these replacement engines fail prematurely. I have case number with Hyundai 41436693

With no warning my car left me sit on the side of the road and when started the engine made an awful knocking noise. Hyundai denied to replace the engine despite there being at least 2 engine recalls. When I asked why they said it was due to no maintenance records so I provided them with maintenance records like they requested and then they deny it again and say they aren’t replacing the engine because the problem with my engine had nothing to do with the 2 engine recalls my vehicle IS affected by.

Airbags failed to deploy. I was involved in a hit and run accident. Vehicle has not been inspected. I had a recall done on it with paperwork confirming it was fixed. I have 4 herniated discs in my back and neck.

This is the first time I have an engine failure. I drove my car 3 min before merging into the route 1 highway. In approximately 800 feet, my car went haywire, all lights in the dashboard went ON, the steering wheel got stiff, and the car speed dropped off, I almost got rear-ended. I made an effort to pull over to the break lane. The car shut off and I could not get it to start. I opened the hood, a light smoke was coming out of the engine. I left it open to make sure it doesn't get worse. After 10 min, a State trooper stopped by to check on my safety, I informed him that I called the insurance to report the incident and request a tow truck. After the tow truck dropped off my car in front of my house, I called a mechanic to check it, he informed me that the engine is seized.

I bought car octv230th little after month as driving engine failure occurred had towed to dealership and they sent to authorized hyndai dealership for the extended warranty campaign. That garage acknowledged problems with the cars engine stating rod bearing clearance and the engine had to be replaced then charged me denied the extended warranty they initially said would classify for. I couldn't keep up with traffic and was very busy almost cause a crash.
