2015 Hyundai Sonata complaints

CAR STOPPED ON THE ROAD LAST WEEK 4/6/26 COULD NOT START HAD TO GET TOWED MECHANIC SAYS NO OIL IN ENGINE RECEIVED OIL CHANGE LAST MONTH

​I will take ​10k$ for the car or a new engine and steering, damages fixed. . I also need a rental by April 10th and $300 for inconvenience thus far. ​The engine ​stalled ​twice​ when driving over 2 months! The lawyer won't be forgiving.

Engine seized driving down the interstate doing 65 MPH in rush hour traffic could have been rear ended or hit vehicles around me trying to get off the road. Complete loss of power. Power steering was still active brakes were barely working. No warning lights (I had the knock sensor recall performed). Engine simply locked up solid. I was able to safely make it to the disabled vehicle lane and put the car in park. Engine had no sludge buildup and looked excellent once it was disassembled by the dealer. All engine bearings had spun. Engine was completely replaced under the extended warrenty.

Hyundai dealership diagnosed my vehicle with engine failure, including a failed compression test and cylinder with no compression, and stated the engine required replacement. The dealership later refused to process the repair and attributed the issue to oil condition, contradicting their prior confirmed diagnosis. The vehicle became undrivable after the diagnosis and has remained in that condition. The refusal to address a confirmed engine failure raises concerns about a known defect and improper denial practices.

The bearing failure from the metal debris had been progressing silently for a long time. You can’t feel or hear it happening gradually. Then at some point the damage crosses a threshold where: ∙The oil can no longer circulate properly ∙The crankshaft bearings completely fail ∙Internal metal parts make contact with each other ∙Everything locks up instantly

The contact owns a 2015 Hyundai Sonata. The contact stated that while driving at an undisclosed speed, the panoramic sunroof detached from the vehicle. The hazard lights were activated, and the vehicle was pulled over to the shoulder of the roadway. The contact attempted to close the cover and was able to close it halfway. The contact stated that on a separate occasion, while driving at an undisclosed speed, the failure reoccurred. The contact pulled over to the side of the road and attempted to close the cover, but the cover failed to close. The contact drove the vehicle while holding the sunroof cover with the other hand. The contact stated that the wind kept lifting the detached panoramic sunroof. The vehicle was taken to a collision center to reattach the panoramic sunroof. The employee removed the panoramic sunroof and placed the sunroof on the passenger seat. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. Upon further investigation, the contact related the failure to NHTSA Campaign Number: 16V726000 (VISIBILITY). However, the VIN was not included in the recall. The manufacturer was not made aware of the failure. The failure mileage was unknown.

My engine is a class action lawsuit and Hyundai refuses to honor their extended warranty because my title has a brand on it. (Odometer issues) My car has been a the dealer for a month and Hyundai refuses even though it's a safety issue and a defect in their design. I want a new engine. The car is perfect otherwise.

FEDERAL REPORT ON TECHNICAL OBSTRUCTION AND WARRANTY FRAUD (THETA II SETTLEMENT) TO: National Highway Traffic Safety Administration (NHTSA) FROM: [XXX] VIN: [XXX] REPAIR ORDER (RO#): XXX VEHICLE LOCATION: Hyundai Shop - [XXX] HYUNDAI CORPORATE CASE: #XXX STATE COMPLAINT (AZ AG): XXX I. CHRONOLOGY OF EVENTS AND EVASIVE TACTICS All documentary evidence has been formally submitted to Hyundai Motor America’s National Consumer Affairs Department, addressed to Case Manager Bryan, at [XXX] and via the official email: [XXX] . STEP 1: Falsification of Title Status (Code A99) Hyundai initiated its denial by alleging that the vehicle held a "Salvage" title status, citing internal code A99. EVIDENCE: I possess a Certified and Stamped Motor Vehicle Record (MVR) from the Arizona MVD, as well as my Clean Title. Mr. Bryan categorically asserted that code A99 "cannot be removed," thereby deliberately disregarding an Official State Certification. STEP 2: Allegation of Negligence (Karen) Corporate representative Karen claimed via telephone that the vehicle's failure was attributable to "negligent maintenance." EVIDENCE: The Official WebDCS report—printed by Mr. Ismael Barragán (Service Drive Manager)—completely refutes this claim; the Blue Link service history indicates "0 FINDINGS." STEP 3: Fabricated Diagnosis and Breakdown of Improper Charges After being compelled by Mr. Bryan to take the vehicle to the dealership for a diagnosis, the narrative shifted to an "Oil Pump Failure." Mr. Ismael Ba

Odometer Fraud. The contact purchased a 2015 Hyundai Sonata. The vehicle was a private sale. The vehicle was purchased on March 1, 2026. The mileage at the time of the purchase was 41,486. The vehicle was taken to the dealer, where the contact was informed that the odometer mileage was last reported at 223,718. The seller was not made aware of the discrepancy.

Engine completely seized while driving.

Rod bearing failure

I was driving on the highway and the engine shut off but everything else remained on. I drifted to the breakdown lane and turned the car off. It would not start again and the car began acting up by turning lights on and off, telling me to check the tire pressure, and not unlocking the doors. I then saw some very light smoke from the engine compartment. I popped the hood and looked and saw a glow on the bottom side of the engine area. Then the car just went up in flames.

Check Engine light is flashing on dashboard. Reduced Vehicle speed. Car will not drive beyond 62 miles.Lost of power during acceleration.

The contact’s daughter owns a 2015 Hyundai Sonata. While driving and coming to a stop, the vehicle lost motive power. There was no warning light illuminated. The vehicle was towed to the dealer where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The dealer informed the owner that the failure would not be covered under warranty due to a lack of engine maintenance on the vehicle. The owner provided the maintenance records. The manufacturer was made aware of the failure, and a case was opened. The failure mileage was approximately 124,000.

My 2015 Hyundai Sonata experienced Service Campaign TX3, TSB# 15-01-022, with an error code of P0010. My car was in the repair shop from Thursday, February 19th, until Thursday, February 26th, being repaired. This cost me roughly $2,300.00 out of pocket. When I attempted to file for reimbursement through Hyundai, I was told they were not reimbursing me. My car experienced failure the first of February. When my mechanic investigated what had happened, it was in fact, due to the service campaign.

I was turning into a parking spot and the car accelerated unexpectedly. I slammed into a snow bank and my front bumper was damaged.

I JUST GOT THIS CAR ABOUT 2 MONTHS AGO AND NOW I AM BEING TOLD I NEED A NEW ENGINE. I JUST LOOKED UP 2015 HYUNDAI SONATAS AND SEE THAT THIS MODEL DOES HAVE REPEAT ISSUES OF ENGINE FAILURE SO I DO NOT UNDERSTAND WHY THIS VIN NUMBER IS NOT UNDER THE RECALL LIST SINCE I AM HAVING THE SAME ISSUE

I am reporting a re-failure of Safety Recall 152. The panoramic sunroof wind deflector, which was previously 'repaired' in 2017 under this recall, has failed again. The broken parts have jammed the sunroof mechanism, preventing it from closing. According to NHTSA Recall 152, this failure poses a severe safety risk as the sunroof glass can detach from the vehicle while driving. The vehicle has only 55,000 miles. Hyundai has currently refused to honor the recall remedy because the 10-year warranty expired 3 months ago, but a safety recall remedy must be permanent and effective.

Engine has knocking sound. Sudden loss of power and hesitation when accelerating

The vehicle suddenly lost power while driving on a public roadway. Immediately after, the vehicle began producing a large amount of smoke. The smoke quickly filled the cabin, making it difficult to breathe and creating an urgent safety hazard. My passenger and I had to exit the vehicle right away due to the amount of smoke. We were exposed to smoke inhalation and were stranded on the side of the road in unsafe weather conditions for over an hour while waiting for a tow truck. I later learned that the vehicle had an open recall related to engine issues; however, I was never notified of this recall. Regardless of recall status, the sudden loss of power combined with heavy smoke and potential fire risk created a dangerous situation that could have resulted in serious injury or death. I believe this issue represents a serious safety defect and fire hazard that could endanger other drivers.

Component/System Failed: Engine – connecting rod bearing failure consistent with Hyundai Theta II engine defect subject to federal recalls and Consent Orders. The vehicle previously received Recall Campaign 953 (KSDS software update), intended to detect premature rod bearing wear. The engine is currently knocking and has been diagnosed as requiring replacement. The vehicle and engine are available for inspection upon request. Safety Risk: Rod bearing failure can cause sudden engine seizure or stall while driving, creating a significant crash risk due to loss of power steering and braking assist. Engine failure DID occurr despite prior recall software update, indicating potential recall remedy ineffectiveness. Sudden stalling in traffic placed myself and others at risk of collision. Dealer Confirmation: Hyundai of North Charleston confirmed through warranty history a prior engine replacement request (PA) was submitted by a previous owner but denied. The recall repair was never performed. Current diagnostic findings indicate engine failure consistent with known recall defect. However, Hyundai has refused to perform further inspection or goodwill repair solely due to the vehicle’s salvage branding. Inspection History: The vehicle has been inspected by a Hyundai dealership. No engine replacement was completed. Hyundai Customer Care has updated case notes but is declining remedy based on title status rather than mechanical condition. Warning Lamps/Symptoms: The vehicle previously

This complaint concerns a repeat failure of both front CV axles on my 2015 Hyundai Sonata. The CV axles and boots were replaced by Gettel Hyundai of Charlotte County using OEM parts in November 2024. The same components failed again just 7,876 miles later in January 2026; requiring a second full replacement. A CV axle replaced with factory OEM parts by a certified Hyundai tech should not fail within 7,876 miles under normal driving conditions. This pattern of repeat failure indicates either * A defect in the OEM replacement parts supplied by Hyundai * An installation defect at the authorized dealership * An unresolved underlying mechanical condition that causes accelerated CV axle wear The rapid repeat failure represents a potential safety hazard. CV axle failure can result in sudden loss of drive power, difficulty controlling the vehicle, and in severe cases, wheel separation --all of which create dangerous conditions for the driver and others on the road. Chronological Timeline of Events: Nov 5, 2024 55,579 miles; both front CV axles replaced by authorized Hyundai dealership using OEM parts. Labor and parts performed per Hyundai standards. Jan 29, 2026 63,451 miles Same CV axles failed again. Second replacement performed at same authorized Hyundai dealership. Total repair cost $3227.16 paid out of pocket by me. Feb 16, 2026 Hyundai Motor America denied goodwill reimbursement request (Case #XXX), citing the malfunction being out of time in service of the vehicle. Reported to

While driving on the freeway, my vehicle experienced a sudden and catastrophic engine failure. The check engine light began flashing, the vehicle lost power, and I almost lost control of the car. I barely had time to pull over to the shoulder to avoid an accident. The vehicle was towed to a Hyundai dealership. The engine does not start and the engine block is cracked. Hyundai denied coverage stating that a software update (Campaign 953) was not installed. Campaign 953 is only a detection update and does not repair or prevent internal engine failure. This is a serious safety issue.

Was driving car and it went completely hot. Towed to a dealership and they said was not drivable and that the radiator support and radiator hose needs replacing and eventually the Drive CV left and front will need replacing or I will be stranded on side of road.

I have been dealing with issues with the turbo that cost over $3k out of pocket to get "fixed" only to have a part go bad and needed to be replaced. Now the engine is bad and needs to be replaced. The dealership is horrible at being honest and treat me as if that's not my only vehicle. I ask for a loaner car and thery never respond!!

Engine locked up

The car is burning a quart of oil a week.

On January 21, 2026, while driving on I-495 at highway speeds (e.g. 50-60 mph) in heavy traffic, my car made a "clunk" sound and I suddently was unable to accelerate. There were no warning lamps, messages, or other symptoms prior to the failure, but immediately when it happened several warning indicators, including the check engine light, oil light, and tire pressure indicator, lit up. The electrical systems and brakes appeared to still work, but the best I could to was coast onto the nearest shoulder and call for an emergency tow. I waited on the shoulder of a busy highway, in the dark, for over an hour. My car apparently has a type of engine that is known for catastrophic failure, so I assume that is what happened. I had the car towed to a Hyundai dealership and they confirmed that the engine needs to be fully replaced.

The oil in the car burns quickly. After driving 2000 miles, there is no oil left. I do not have any oil leaks anywhere. It’s just burning oil. This has been consistent since I’ve gotten the vehicle.

While driving my 2015 Hyundai Sonata, the vehicle suddenly lost power and entered limp mode. A loud engine knocking noise was present, and acceleration was severely limited, creating a safety risk in traffic. The check engine light illuminated at the time of the failure. An independent mechanic confirmed diagnostic trouble code P1326, related to the engine knock sensor detection system designed to detect early engine bearing failure. The condition occurred without warning. The vehicle is currently not being driven to prevent further damage and is available for inspection upon request. Sudden loss of power while driving poses a serious safety hazard. This appears to be a known engine defect affecting similar vehicles.

We have had issues with tires not wearing equally and tears on the inner tire/s shortly after replacing. This has happened twice so far. This has lead to air loss, severe vibration, and pulling while driving. Most recently, both back tires were losing air with one back tire having a structural issue on the inner portion of the tire making it unsafe to drive. We had just put on new tires in 1/2024 and had to replace one of those before this issue because of a tear on the inner portion. Both back tires were replaced and rotated. Severe vibration and pulling occurred. We took it in to have balancing and an alignment done only to find out that all 4 rims are bent to varying degrees on the inner lip that meets with the tire. All 4 tires were wobbling significantly during the service to balance resulting in the inability to balance the tires. As there hasn’t been any occurrence that would have caused all 4 rims to bend in the exact same place, and reading about the defects of the coating on the rims as well as other wheel related issues, we felt it necessary to file a complaint. Living in a state where there is salt put on the roads as well as salt in the snow itself, peeling and premature wear to the rims due to the lack of a safe and sufficient coating, exposes the metal to the elements and excessive salt during the winter months. This in turn weakens the metal making it susceptible to bend and sustain damage it would not otherwise sustain. We now have to replace all 4 rims to el

My 2015 Sonata will stall out dropping speeds to 12-24 when i slightly merge, when I turn ect. Then it won’t accelerate for what seems like 10 minutes realistically 2 minutes maybe 3 Then will slowly regain speed. I’ve almost wrecked twice Share care with daughter and she’s been victim to it way way more. This is scary and Hyundai won’t stay behind their product Local dealership won’t fix recalls so we have to go over 120 miles for repairs. The recall isn’t even for transmission engine

On the day of Friday may 16, 2025. I was returning from work on 35 going south in Dallas, Tx. the engine seized leaving my vehicle in a neutral state. I was in the furthest left lane(passing lane). Lord willing I had enough motion to safely exit on Illinois ave without injury of myself or others. the starter could no longer turn the flywheel indicating to me that the crank shaft had seized. i inspected the oil; it was low but no warning light ever came on(the dealer recently stated the oil was fine when they performed a multipoint inspection(5/10/25) when I went in for the gov mandated theft software update as my car had recently been attempted to be stolen), no sort of warning light came on, nor did the ksds update do anything just like countless other kia/hyundai owners who's engine seized on the interstate. I towed the car to clay Cooley Hyundai Dallas because my research indicated that theta 2 engines had government mandated extended warranty even for subsequent owners however as I didnt drive it often & had only replaced the oil(I change every 3k and was soon to do another) once, because I've only owned car for around 6k miles(purchased 10/30/24 I think)before it seized. Hyundai denied txxi claim, stating engine didn't seize due to connecting rod bearing failure, further stating, it was neglect. they said my valve train look terrible. well its going appear so as the theta 2 was inherently known for poor oil flow, major oil consumption, rough crankshafts & improper deburr

The vehicle experienced sudden engine failure due to rod bearing damage. The engine seized without warning and required towing. A Hyundai dealership confirmed rod bearing failure consistent with known Theta engine defects. Hyundai denied engine replacement coverage because a software update (Campaign 953 / KSDS) was not completed; however, I never received notice of this campaign. The campaign does not appear on the NHTSA VIN lookup for my vehicle, and it was still listed as outstanding in Hyundai’s system at the time of failure. The sudden engine failure created a safety risk due to loss of power.

I've had my 2015 hyundai sonata now for A year. i took it to the hyundai place to have recalls on the security fixed. and told them about the valve cover gasket leaking. they said they fixed it. however every since i took it to the dealership i have had nothing but problems. my car makes a rattling noise when i accelerate, i smell a strong gas smell occasionally at random times but always while driving. my driver brake light has never worked, my driver headlight keeps blowing, my airbag light is now coming on randomly, my car has a bag vibration while going down the road, when i let off the gas it stops and i have replaced tires and still it won't go away no matter what i have done to fix it , and there has been many times after i return home the smell of something burning as off something is on fire is coming from my car. i have even been in panick thinking something today home was on fire but the smell was coming from my car. and others have even stated they smelled it as well. i've already taken out two loans to fix the valve cover gasket and the fuel pump filter, i can not keep taking out loans to fix problems that appears to be problems from the manufacturer and same problems others have had due to malfunctioning issues. i have children that ride in my car, i would hate for someone to get hurt or worse bc of manufacturing problems. then hyundai would have a bigger problem on their hands.

VEHICLE IS PUTTING OUT A VERY STRONG GASOLINE ODOR, ESPECIALLY WHEN SITTING IDLE. I LOOKED UP PREVIOUS RECALLS ON THE VEHICLE AND SEEN WHERE THERE WAS A RECALL I BELIEVE IN 2022 FOR SIMILAR ISSUES.

The engine has failed and I was then i formed that there was a arbitration settlement that Hyundai were replacing engines under this settlement. I was not informed of this and now they are saying it has expired. I would like for them to honor this and repair my engine under the Hyundai Theta engine defect lawsuit

My vehicle suffered a sudden engine failure that Hyundai confirmed was caused by a recall defect. Hyundai replaced the engine but is refusing to reimburse several necessary expenses incurred solely because of the recall-related failure. There was no warning lamps or messages prior to failure. Expenses: Monthly loan payment while car unusable – $242.55 (REFUSED) First tow: Highway → Old Ox – $160.00 (REFUSED) Second tow: Old Ox → Alexandria Hyundai – $170.00 Third tow: Alexandria Hyundai → Exxon – $200.00 Fourth tow: Exxon → Fitzgerald Hyundai – $205.00 Alexandria Hyundai inspection – $199.99 (REFUSED) Old Ox diagnostic fee – $539.24 (REFUSED) Rental car 10/4–10/8 – $208.90 Rental car 10/29–11/1 – $151.00 Total requested: $2,076.68 Total refused: $1,141.78 Hyundai claims the initial tow isn’t covered because it wasn’t to a Hyundai dealer, that independent diagnostics “don’t qualify,” that a Hyundai dealer’s inspection fee is not reimbursable because dealers are “separate entities,” and that my loan payment is not covered. These denials contradict Hyundai’s recall guidance and the requirement to reimburse reasonable and necessary costs caused by a recalled defect. This engine failure also placed me in real danger. The engine died suddenly at highway speed, leaving me stranded in an unsafe location with no control over the tow provider. Hyundai Corporate then instructed me to bring the car to Alexandria Hyundai, creating the clear impression those fees would be reimbursed. I rel

Engine failed on 10/24/2025. Hyundai will not honor class action suit to repair engine at no cost to owner. Hyundai state recalls were not completed on the car prior to engine failure. We agree, recalls were not completed prior to failure. Because we never received notification. Had we received notification we would have acted on the recalls immediately and not put our safety, that of our children or the general public at risk by driving a vehicle with an engine that could fail at any moment. We have contested Hyundai's rejection several times to no avail. We are seeking guidance in resolving this mater.

The contact owns a 2015 Hyundai Sonata. The contact stated that while driving at 45 MPH, the vehicle suddenly stalled. The vehicle was parked on the side of the road and failed to immediately restart. The vehicle was later restarted and driven to the residence. The vehicle was taken to the local Auto Zone, but the cause of the failure was not yet determined. The vehicle was then taken to the local dealer to perform a diagnostic test. No further info was available, and the vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was 55,300.

My 2015 Hyundai Sonata has a defective engine. The motor failed unexpectedly even though the car has low usage and has always been maintained properly. I was informed that many Hyundai engines from these years came with manufacturing issues, and mine appears to be one of them.

My 2015 Hyundai Sonata has a defective engine. The motor failed unexpectedly even though the car has low usage and has always been maintained properly. I was informed that many Hyundai engines from these years came with manufacturing issues, and mine appears to be one of them. I am requesting that Hyundai replace the engine or provide a proper solution since this defect is not due to misuse but a faulty motor that came from the manufacturer. I need this resolved as soon as possible because the car is not running at all.

While I was driving at approximately 55mph, a loud clank happened and the car stalled, and smoke started pouring out of the hood and through the vents into the cabin, and I was leaving burning pieces behind on the road. I pulled over, ran to the back to get my dogs out of their crash tested kennels in the backseat, and both rear doors & passenger front door were locked. I ran up front to unlock them, and the unlock button did not work. I tried the unlock on the keys and it did not work. Due to having a recommended crash safe kennel set up it was not possible to crawl into the back to open it from the inside. My dogs were trapped in a car that was filled with smoke and on fire for over 2 minutes while I debated breaking the windows. I managed to fish a wire into the back to unlock and pull the door open from the inside of the back doors. The car stopped burning but was still smoking for several minutes after & I was able to clear the smoke to make it safe for my dogs to wait for a tow. When the mechanic looked at it he said the engine blew up due to the rod shattering into the block, destroying the entire engine and spilling oil which lit on fire. Mechanic recommended I contact Hyundai for engine replacement as this was a known issue with other 2015 Hyundai sonatas which were recalled due to risk of a defect rod knock causing the rod to shatter causing high speed stalling. Hyundai says my engine was not included in that specific recall. I included photo of the shattered rod wh

The vehicle’s sunroof just flew off the car at 31 miles per hour (the whole part), Hyundai had a safety recall for that and it was done in the past, the problem is that happened exactly what the recall were suppose to prevent, it was my wife and 2 kids on my car and I’m glad it was before she enter the highway, it would cause a major wreck with multiple vehicles. The car behind her had a dash cam and recorded the event, I’ll upload for better understanding. I’m also posting it on the social media to get publicity on the event.

I heard noises immediately after purchasing the Sonata. I took it back in to Carmax ( where I bought it from) multiple times and was told they didnt find anything wrong. As time went on, I took my sonata to Hyundai dealer to get checked out. 1st time they told me, Hyundai wouldnt cover the cost to check out engine & that it would be $700 to take a look. The 2nd time, I was told we cannot check it out because the engine light isnt on. Basically they couldnt scan/check codes without the light being on. I suggested that if they just rode around the block, that they would notice that there's an issue. They still said no. Then back in February, I took back to Hyundai dealer again & they did check it out because the engine light was now on. That inspection came back as the cylinder was bad. Hyundai doesnt cover it because at that point it was past 100k miles and I was not the original owner. I asked about 100 mile.warranty when I bought it at carmax and was told yes 100k warranty still applies. So upon further research, hyundai has had problems with this year/make/model/ engine type before. If they knew something was wrong with it, why not just say so & fix it? Or as soon as I seen the first issue, check it out and repair it for me?

The engine/powertrain on my 2015 Hyundai Sonata (VIN: [XXX] ) has failed due to extremely low compression in all four cylinders, causing severe misfires, hard starting, loss of power, and intermittent rattling noises, and the vehicle is currently available for inspection at the Hyundai dealership. This failure created a safety risk because the engine hesitates, struggles to start, and can stall or lose power during driving, which could lead to a loss of control or an inability to accelerate in traffic. The problem has been confirmed by both an independent mechanic and the Hyundai dealership, who documented low compression across all cylinders. The vehicle has been fully inspected by the dealership on Hyundai’s behalf after I opened a case with the manufacturer. Prior to the complete failure, the car showed warning symptoms such as repeated cylinder 4 misfires, rough starting, reduced power, rattling noises on startup, and the check engine light appearing several times beginning earlier this year. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The paint started peeling off in large sections.

On the highway, my 2015 Hyundai Sonata suddenly began making a squealing or metallic rattling noise. At first, I thought it might have been something loose inside the vehicle. Within moments, the check engine light began blinking, followed by several additional warning lights and a pronounced knocking noise from the engine area. Immediately after the warning lights appeared, the vehicle entered a reduced-power “limp mode” and began rapidly losing speed, even though the engine was still running. Because this occurred at highway speed while surrounding traffic was traveling normally, I had to pull onto the shoulder to avoid being struck. This created a significant safety hazard. I was stranded for approximately 45 minutes on the shoulder, at risk of being struck by other vehicles passing at high speeds. A tow truck arrived before the highway patrol, and the vehicle was towed home. When I returned home, my code reader pulled two versions of diagnostic code P1326, which is associated with potential engine bearing failure in Hyundai Theta II engines. The issue has since been inspected by the dealership, who confirmed the presence of the P1326 code. The vehicle is currently available for further inspection upon request. There were no prior symptoms that I was aware of leading up to the incident other than the brief squealing/rattling noise and the sudden warning lights immediately beforehand. The failure happened suddenly and without warning, causing an immediate and unexpected los

At about 30mph the sunroof suddenly flew of of my car and almost hit the car behind me thst had to avoid the flying part, for a good luck it didn’t cause a major accident because I was about get in a busy highway and this hazard could’ve caused a major ctash envolvimg multiple cars, the vehicle behind me has a dashcam that recorded the event. For God nobody got injured.

1. Description of Safety Problem: My vehicle experienced a sudden catastrophic engine failure while driving, resulting in a complete loss of power and severe engine knocking. This is a known safety defect related to the Theta II engine (specifically, connecting rod bearing failure, often referred to as the KSDS defect) that poses a severe risk of stalling and engine fire. The failure rendered the vehicle inoperable and unsafe. 2. Manufacturer's Failure to Honor Safety Recalls & Warranty: Despite this being a known, documented defect covered by Hyundai's own Technical Service Bulletin (22-EM-00H-1-1) and the TXXI Class Action Settlement—which provides a "Limited Lifetime Warranty" for this issue—Hyundai Motor America has repeatedly and wrongfully denied my warranty claim. Furthermore, I discovered through Hyundai's official campaign portal that my specific VIN had multiple unperformed safety and service campaigns, including critical Engine Control Module (ECM) updates (Campaign #953) designed to monitor and prevent this exact type of engine failure. Hyundai's failure to ensure these critical updates were performed constitutes negligence and directly contributed to the safety failure I experienced. 3. Evidence of Manufacturer Bad Faith: I have obtained documented proof that Hyundai has approved and performed zero-cost engine replacements for the identical defect on vehicles with mileage exceeding 180,000 miles. This proves that my denial is arbitrary, discriminatory, and demons
