2013 Hyundai Sonata Engine Problems

Engine was replaced couple of months ago due to a recall and today 3/30/2026 I'm pulling up to my driveway getting home from work in my car starts smoking it catches on fire

Engine died because oil wasn't changed, even though the car wasn't due for an oil change and no indicator flashed on the dashboard warning us that maintenance was needed.

No warning whatsoever. Car drove like a dream. All maintenance up to date. Oil changes done exactly on time. All recalls completed. Then all of a sudden while on the interstate, car started knocking extremely hard, lights on dash came on and car died. Almost caused several wrecks as I was going 70mph. This happened March 2026. Vehicle is a 2013 with 105,000 miles on it. 1-owner vehicle with clean title.

I was driving in highway and just engine lockout and vehicle shutdown

3rd time in the last 6000 miles the knock sensor came on and the dealer clears it, charges me repairs and sends me home with the code cleared car. All 3 times the car imeditently kicked into limp mode while I was on the highway at high speeds, suddently being slowed without warning. When checked with a local scanner it showed P1326 code and dealers all confirmed it. First incident happened in Utah in 2023 (108949miles) and the last 2 happened in michigan in 2025(114850 miles) and now 2026 (115890 miles).

My 2013 Hyundai Sonata has a replacement 2.0T Theta II engine. Recently, it developed a fuel leak that identically matches the description of Hyundai recall Recall 22-01-047H (NHTSA #22V-312). I have attached a description of my fuel leak as assesed by a Hyundai dealership alongside a .pdf of the NHTSA safety recall report to demonstrate that the issue is identical. Hyundai corporate is refusing to acknowledge that this is an identical issue and that my exact VIN group for 2013 Sonatas should be included in this recall. This issue represents a serious risk to life and property that Hyundai is refusing to officially address. They have refused to cover repairs for this issue. Additional info: my car has 124,047 miles on the odometer, but this replacement engine only has about 26,000 miles on it.

Hi, I recently bought my car with a savage title, the inside of the engine in my 2013 Hyundai sonata is making a knocking noise, it has the engine light on and when I scanned it, it shows code P1326, I did some research and found out that Hyundai issued a safety recall 162 back in 2017. In the Hyundai recall webpage records it shows the recall as complete on 8/7/2020. However the engine is making the knocking noise. I took the car to the dealer (Oxmoor Hyundai in Louisville) to have it checked for that safety recall on 2/2/2026 and it was not checked until 2/12/2026 and they told me that they applied for an engine replacement that day, then on 2/18/2026 dealer reached out to me saying that my engine replacement was approved and that they were waiting for the engine to be delivered between 5 to 7 business days. Then on 2/19/2026 I received a call from the dealer and they told me that the engine replacement was not approved due to the title being savage, I asked why was that if it was a safety recall and she responded back saying that it was not a safety recall, it was just an extended warranty, I asked for more explanations on why if it was already approved why did it change the next day and they told me that I had to call the Hyundai customer service. I called the Hyundai customer service line on 2/20/2026 and they told me that they were going to reach out to the dealer about this issue. I haven't had any updates after that.

Engine losing power and metal shavings in oil and engining shutting off

It is a known issue on several makes and years on Hyundais. excessive oil consumption. burning a quart every 375 miles. at one point we had no oil in the car at all. causing a potential major safety issue lubricating parts of the engine. etc. we have contacted Hyundai several times and brought to Hyundai dealer who has confirmed issue through a test. no warning that oil was low!

The contact owns a 2013 Hyundai Sonata. The contact stated that while driving at an undisclosed speed, the vehicle stalled, with an abnormal knocking sound coming from the engine compartment. The check engine warning light was illuminated. The contact was able to restart the vehicle; however, the failure persisted. The contact previously received notification of NHTSA Campaign Number: 17V226000 (Engine and Engine Cooling). The vehicle was taken to the dealer, where it was diagnosed, and determined that the engine short block had failed and needed to be replaced. The contact was informed by the dealer that the vehicle would not be serviced under the recall. The contact was offered a buyback option for the vehicle and was also offered a loaner vehicle. The vehicle was not yet repaired. The manufacturer was made aware of the failure. The failure mileage was not available.

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 ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2013 Hyundai Sonata (VIN: [XXX] , 2.4L Theta II GDI engine) is experiencing symptoms consistent with the known Theta II engine defects covered under prior NHTSA recalls (e.g., 17V-226) and the related class action settlement for connecting rod bearing wear due to manufacturing debris restricting oil flow. The vehicle has begun exhibiting [describe your specific symptoms here, e.g.: "a loud metallic knocking/tapping noise from the engine that increases with RPM, especially during acceleration or at highway speeds; reduced engine power and hesitation; illumination of the check engine light and/or oil pressure warning light; excessive vibration; or sudden loss of power/stalling risk"]. These issues have [escalated/worsened over time or occurred suddenly while driving]. This poses a serious safety hazard because premature bearing wear can lead to complete engine seizure or stall without warning while the vehicle is in motion, potentially at highway speeds, resulting in loss of motive power, inability to maintain speed, or increased risk of collision, injury, or fatality. I have properly maintained the vehicle with regular oil changes using the recommended full synthetic oil [add if true: "and can provide service records showing no evidence of sludge or neglect"]. Despite submitting an appeal/claim under the Hyundai Theta Engine Class Action Settlement (Case Number XXX), I received confirmation on December 30, 2025, promising a decision within 14 business days, but as of January 16, 2026, there has been no response or update despite follow-up attempts. This ongoing delay prevents me from obtaining the necessary inspection, repair, or replacement under the extended warranty/safety coverage, leaving the vehicle in a potentially unsafe condition. I am requesting that NHTSA review this as part of the pattern of Theta II engine failures in 2011-2014 Hyundai Sonatas, which have led to thousands of similar complaints, recalls, and investigations into untimely INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

See attached document for complaint.

My engine recently seized on my vehicle and Hyundai is refusing to replace my engine. Per their website my vehicles engine has a lifetime warranty. This warranty is eligible for class vehicles who have has to campaign 953 reformed on their vehicles prior to engine failure. This was performed in n my vehicle on April 16, 2019. Per Hyundai’s website. I am being offered a settlement I did not take part in instead of my engine replacement and it should be illegal for them to go against their own word.

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.
