My 2013 Hyundai Sonata qualifies for a Lifetime Warranty engine replacement under the Theta II Class Action Settlement. The dealership is refusing coverage unless I provide maintenance records, even though the settlement prohibits denial based solely on missing records or the presence of sludge. Hyundai must prove neglect caused the failure, which has not been demonstrated. I am requesting review by the Engine Settlement Team and approval of my engine replacement.
Vehicle: 2013 Hyundai Sonata VIN: [XXX] Mileage: [163,000] Summary: Theta II 2.4L GDI engine bearing failure (Recall 953 / 20V-393) -?" severe knocking, risk of sudden engine seizure/fire. Dealer refuses lifetime-warranty repair and forced consumer to pay towing to avoid lien/fees. Description: This vehicle is covered by NHTSA Recall 20V-393 (Campaign 953) and the court-approved Theta II engine class-action settlement providing a lifetime warranty for rod-bearing failure. The engine now has loud knocking from failed rod bearings -?" the exact defect addressed by the recall and settlement.On 11/28/2025 I dropped the vehicle at Group 1 Hyundai Southwest Houston (10301 Southwest Fwy, Houston, TX 77074) for diagnosis and repair under the lifetime warranty. The dealership confirmed bearing failure but refused to repair, stating the vehicle is -??not eligible-?? because the free Campaign 953 knock-sensor software update was never performed. No owner (current or prior) ever received any recall notice or settlement notice despite Hyundai-??s legal duty to notify all registered owners.On 12/04/2025, service advisor Tevin told me to remove the car by Friday or face storage fees and possible lien sale. To avoid unlawful charges for a known safety defect, I paid $192.70 out of pocket for AAA to tow the vehicle off the lot on 12/05/2025 (receipt available).Hyundai is using its own failure to provide notice as justification to deny legitimate lifetime-warranty claims and shift costs to consumers. The unrepaired vehicle remains a serious safety hazard (engine stall/fire risk) on the road.Requested Action: Investigate Hyundai Motor America and its dealers for (1) systemic failure to notify owners of Recall 953 and the Theta II settlement, (2) wrongful denial of lifetime-warranty engine repairs, and (3) imposing towing/storage fees on consumers for admitted safety defects. I have filed a claim with the settlement administrator and can provide receipts, recorded calls, and docs. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION A

The contact owns a 2013 Hyundai Sonata. The contact stated while driving 55 MPH, the vehicle shut off unexpectedly and failed to restart. The engine warning light was illuminated. The vehicle was towed to an independent mechanic who determined that the failure was caused by the starter. The mechanic informed the contact about an engine recall. The vehicle was taken to the local dealer and the contact was informed that the vehicle was working as designed. The starter was replaced. While leaving the dealer lot, the vehicle shut off. The dealer informed the contact that the spark plugs needed to be replaced. The vehicle was not repaired. The manufacturer was contacted, who informed about a monetary compensation, a starter, or a repurchase of the vehicle. The failure mileage was approximately 198,000.
Driving at 70 mph on the highway, the engine seized without warning. The car violently shuddered and rapidly decelerated in the travel lane. A fully-loaded semi-truck was directly behind me and had to swerve violently and brake hard to avoid crushing my vehicle. This created an immediate, life-threatening risk of a catastrophic, high-speed rear-end collision. The failure is with the internal engine assembly (likely connecting rod bearings) and is available for inspection. The dealer confirmed the engine failure but denied the repair. This is a known defect. The "Engine Oil Pressure" warning light flashed and a loud engine knocking began moments before the total power loss. This is a dangerous defect that causes sudden, unpredictable stalling at highway speeds.
I bought this car before less than 3 months when. When I was drive the car on [XXX] the car just stop stopped no power without any warning when the car stop I just came from home. It-??s far it-??s like the distance between my home and the place the car stop in the highway. It-??s like 5 miles. when I park the car to the side road right side road I open the hood. I see some smoke coming from the engine and smell like fire or burn or some plastic fire. I-??m a mechanic he said before I bring the mechanic I seen that the screen light it-??s like a car with the key in the middle of the car. The picture is the light the car stop starting. I thought I call somebody he told me maybe the car is the program or disconnect. We need to program it or they bring the battery I bring a battery. I tried to start the car again. It-??s not working the mechanic. He told me that starter. I bought the starter and I start in the car. You still not working they told me after that. They told me the battery maybe I checked the battery I took the AutoZone. I took the battery. It was 95%. I called the company and the company.

The car was being driven from Virginia to Austin, Texas. In Tennessee within 10 miles of Jackson, TN, on [XXX] the car suddenly lost power and the engine light started flashing and could not be driven above 60 MPH (the speed limit there was 75 and the car was being driven at the speed limit until this occurred). Even though the car lost power, the temperature remained steady and was driven to a car repair place and the next day it was towed to a nearby Hyundai dealership in Jackson, TN where they declared the engine needed to be replaced. This was also confirmed by our insurance company, Progressive. Ran the VIN and the car is an affected vehicle under Service Campaign 953 and engine should qualify for lifetime warranty but Hyundai is trying to deny the claim due to bogus claim of "Exceptional Maintenance Neglect" which is not even close to true. The car had an oil and filter change a few days prior to the start of the trip and had been well maintained prior to that as well.

I am filing a complaint regarding my 2013 Hyundai Sonata in connection with a known recall related to connecting rod bearing wear (I believe this is Recall 198). My vehicle is experiencing issues consistent with this defect, but Hyundai has denied my warranty/recall claim. Hyundai-??s denial was based on an allegation of -??engine neglect, -?? which is not accurate. I have maintained my vehicle with regular oil changes since purchase, and I have records to support this. I work from home and therefore do not drive as frequently as the average commuter, but I have always performed at least the standard minimum maintenance required. The car has never shown signs of engine neglect or had prior engine issues until now. The failure occurred while I was driving on the highway, when the engine suddenly stopped running. This placed me in a very dangerous situation, as the car stalled in active traffic and posed a risk to myself and other drivers. This highlights the serious safety hazard associated with the known rod bearing defect. Since the failure, I have been left without reliable transportation, and it has been extremely difficult to get to and from work. The problem was reported to my Hyundai dealership, but they are refusing to cover the repair and appear to be attempting to avoid responsibility for this recall. Even if the specific recall campaign is now listed as closed, this is a well-documented defect, and Hyundai should remain obligated to fix it when it occurs. I am requesting NHTSA-??s assistance in ensuring Hyundai is held accountable for honoring their obligations under the recall. Consumers should not be penalized thousands of dollars for a safety defect that is the manufacturer-??s responsibility.
This has been going on nothing resolved and no cooperation. Im going yo locate an Attorney that really don't want to. Requesting this be, the situation be loojedvatb, at no chargevand replace whatbwasvsuppisedly replaced by Steele South Loop Hyundai, Houston Texas, sold to Keating groupbbased out if Texas.

The contact owns a 2013 Hyundai Sonata. The contact stated that while her sister was driving at various speeds, there was an abnormal, fuel odor coming from the vehicle. Despite the odor, the contact's sister resumed normal driving operation and later refueled the vehicle. After fueling the vehicle, the fuel odor was stronger, and the tire pressure warning light was illuminated. The contact's sister pulled over to inspect the vehicle, but found no failure. The next day, upon starting the vehicle, there was smoke coming from under the hood of the vehicle. The vehicle was taken to an independent mechanic, where the mechanic immediately smelled a fuel odor and later discovered a fuel leak while inspecting the vehicle. The mechanic showed the contact the fuel leak and diagnosed the vehicle with a defective fuel system. Upon investigation, the contact linked the failure to NHTSA Campaign Number: 18V934000 (Engine, Fuel System, Gasoline); however, the VIN was not included. The vehicle was not repaired. The contact attempted to reach the manufacturer but was unsuccessful. The failure mileage was 192,000.
