general problems of the 2013 Hyundai Sonata - part 1

On September 8, 2026, while driving a 2013 Hyundai Sonata limited at highway speed, the check-engine light began flashing and the vehicle suddenly lost power. The vehicle slowed to approximately 40 mph, then approximately 20 mph, before the engine completely shut off. I had to maneuver the vehicle to the side of the highway while surrounding traffic continued traveling at highway speeds. This created a serious risk of a rear-end collision or other accident. The engine would not operate afterward and appears to have seized. The vehicle had approximately 100,000 miles at the time of the incident. There had been no clear warning of an imminent engine failure before the check-engine light began flashing and the vehicle lost power. The vehicle has not yet received a complete diagnostic inspection, so the precise cause of the failure is currently unknown. The vehicle is available for inspection upon request. No crash, fire, or injuries occurred, but the sudden and severe loss of power created an immediate safety hazard.

I am reporting a serious engine failure involving my 2013 Hyundai Sonata. The vehicle's engine was previously inspected by a Hyundai dealership as part of a Hyundai engine recall. I followed Hyundai's instructions and brought the vehicle to the dealership for the required inspection. I was informed that the engine passed the inspection, and an orange marking was placed on the oil dipstick. The Hyundai dealership should have the service record documenting this recall inspection. Many years later, at approximately 120,000 miles, the same engine suddenly failed without warning and became locked/seized. A mechanic attempted to turn the engine and determined that it would not turn. I understand that many years had passed and the vehicle had accumulated additional mileage since the recall inspection. I am not claiming that the previous recall issue necessarily caused the current failure. However, I believe the circumstances warrant investigation because this is the same engine that had previously been inspected under a Hyundai engine recall and determined to have passed the inspection. The vehicle had been routinely maintained. Much of the routine maintenance was performed outside Hyundai dealerships by a mechanic in my family and by me, so the Hyundai dealership service history may not contain all maintenance records. I am concerned that the sudden engine seizure may represent a safety-related engine defect or may potentially be related to the previously recalled engine condition. An unexpected engine seizure can result in a sudden loss of propulsion and create a significant safety risk if it occurs while the vehicle is being driven. I am requesting that NHTSA review this complaint, including the vehicle's recall history and any related complaints or investigations involving the 2013 Hyundai Sonata, and determine whether this failure warrants further investigation. The Hyundai dealership that performed the recall inspection have documentation of that inspection.

My engine was decreasing in speed and shutting off if I brake to slow down on major exressways and local roads. I was advise by my dealership mechanic shop that my engine had a recall and need to have it towed to a Hyundai service dealer for a replacement engine . My engine light on the dashboard had a constant blinking light. My vehicle was inspected camelback Hyundai and a new engine was replaced. The dealership is holding my vehicle hostage demanding I pay 2500. 00 for replacement engine that was a recall. They are threatening to place an abandonment charge against me.

The contact owns a 2013 Hyundai Sonata. The contact stated that while driving 40 mph, the vehicle suddenly lost power. The contact was able to coast to the side of the road and turned off the vehicle. The vehicle was unable to restart on the side of the road. The vehicle was towed to a certified mechanic who diagnosed that the engine had seized and needed to be replaced. The vehicle was then towed to the dealer, who confirmed the diagnosis. The dealer asked the contact to provide receipts of past oil changes. After submitting the information to the manufacturer, the request to cover the repair was denied. The vehicle remained with the dealer for a month. The manufacturer was informed of the failure by the dealer. The failure mileage was 52,973.

I was on [xxx] . I was going 70 mph and then my car just instantly stopped accelerating. The check engine started flashing and I pulled to the side. There was a knocking noise and I just stopped. I called my son to come and get us and then my uncle told it to my house. I have several friends that work on cars and have a a tester. Of course they tested it in that same code came up as if it was the knocking center, so I had another friend come and tested with a different tester with the knocking sensor out his own cylinder three it’s not the knocking center the bearing in the motor is on cylinder two, which that’s what it is. I put my pen. I I put my pin number on the website and it’s showing that my car is affected. No it’s not showing on y’all‘s recall because it’s not something that you’re gonna recall. I have a history of my car motor being fixed every six years if I need to provide that, I will email that I’ve been given the runaround to get my car fixed because it’s not showing up on y’all recall, but it is a recall for the bearing in the motor we could’ve gotten hurt no warning no nothing. I just want to be done right because I’ve had my car service for the last six years and nothing went wrong. I just want y’all to be fair and do right and put that on y’all’s recall, I would hate to take this further but if I have to, I will sincerely [xxx].

Bought car from a used car dealership, car fax report filed 3 other owners, with a well maintenance report on file with oil change done atleast every 5k miles. Bought car in January 2026, maintenance had been done before car was taken off the lot. At 3k miles since hsving the CA on 05/15/26 I got my oil changed and cabin filters replaced. It’s only been less than 1500 miles and car engine had reportedly seized.

When my father was driving, the vehicle stalled out with no prior odd activity. He pulled over to the side of the road and attempted to start the vehicle. He saw smoke, opened the hood, saw flames and cleared the area of the vehicle. Due to the large Hyundai/kia engine recall for his year of vehicle, the engine had been replaced 2-3 times and only ever been serviced by the dealership. We do not know if all recall repair work had been done, because there was also a fuel line recall which was "fixed" in 2020 and 2022.

I am writing about my 2013 Hyundai Sonata VIN: [xxx]. On [xxx] my vehicle experienced a knocking noise from the engine and the illumination of the check engine light. The car lost power and I was unable to drive it home. I had to call a tow service to have the car towed to alan turner Hyundai, 6501 pensacola blvd, pensacola, FL 32505. I spoke to a service writer at alan turner Hyundai. He told us that they could not help us and to contact Hyundai corporate office for help. We purchased this car brand new from alan turner Hyundai. We visited your web site and put in our VIN and the system stated that our vehicle was affected by the Sonata and santa fe sport engine recall campaign. We are an [xxx] with one car, and that car has stopped working. We need help in getting this car repaired under warranty via the Sonata and santa fe sport engine recall campaign. Thank you.

Engine developed a loud rod-bearing knock at approx. 107,771 miles, consistent with the theta ii gdi connecting-rod bearing defect addressed by NHTSA recall 17v-226 (Hyundai recall 162). The vehicle was taken out of service and delivered to webb Hyundai, highland, in, on 06/13/2026, where it remains. Hyundai's own campaign records confirm recall 162 (gdi engine inspection/replacement) was completed on this VIN on 10/02/2017 and the ksds engine-monitoring software (service campaign 953) was installed 08/09/2019 - yet the engine has now failed in exactly the manner the recall was meant to remedy, indicating the recall remedy was ineffective for this vehicle. Hyundai motor America (case #42847594) has refused repair, citing a "branded title"; the only brand on the title is a "not actual mileage" odometer disclosure, not a salvage or rebuilt brand. Nhtsa guidance is that title branding is not a valid basis for denying a recall remedy. The defect poses a risk of sudden engine failure and stalling while driving. No crash, fire, or injury. Requesting NHTSA review of recall remedy effectiveness and of Hyundai's denial.

My vehicle began experiencing excessive oil consumption several years before the engine failed. In approximately 2019, I reported the oil consumption to an authorized Hyundai dealership and expressed concern that my vehicle might have one of the known theta ii engine defects. I was told the knock sensor detection system (ksds) campaign had been completed and that my vehicle was not one requiring engine replacement. The excessive oil consumption continued. On June 6, 2026, the engine developed severe metal knocking, misfires, and became unsafe to operate. I was concerned the engine could fail completely or lose power while driving, creating a safety hazard for myself and others. The vehicle had to be towed to a Hyundai dealership on June 7, 2026. Hyundai of kennesaw inspected the vehicle and verbally advised that the engine failure was caused by connecting rod bearing failure. Although the dealership identified connecting rod bearing failure, Hyundai motor America declined to replace the engine and instead advised that it would not proceed with repairs because of the settlement provisions related to the vehicle's age and mileage. As a result, the vehicle remains inoperable. I am submitting this report because I believe this engine failure presents a significant safety concern due to the potential for sudden engine failure or loss of power while driving. I am also concerned that I reported symptoms years before the failure, yet the engine ultimately failed from the same type of defect associated with many Hyundai theta ii engines.

Driving my car, oil light comes on. I take to a local mechanic who said he sees this often, my engine is going to seize up and confirmed via VIN my car is affected by the Sonata engine recall campaign xxx. Vanessa at Hyundai said to take it to a dealership immediately for further inspection as it may not be safe to drive. Took to dealership on xxx. While at the dealership, service manager said on xxx “my car was perfect, didn’t know why it was even there and trying to find something wrong with it was like chasing unicorns. ” I said please look again and on xxx the engine seized up as it was taken on a drive by said advisor. Via dealership, they took pictures of manifold, but Hyundai denied my replacing my engine per the recall. I called Hyundai to request an appeal and received a case number/case manager ( madge case # xxx) on xxx. I then submitted maintenance records which showed at least one oil change at each requested interval and still denied on xxx. I continued to call both parties: dealership & case manager but got no reply. I received my case manager’s direct line at Hyundai on xxx via [xxx] who said no notes were on file and case manager would return call in 1-3 days and he has never returned my calls, nor has the service manager who said my car was in perfect driving condition. Today is July 8 and I am still waiting for a written letter or phone call explaining the reason for my denial. Napelton Hyundai is also charging me $215. 00 for the engine inspection when my paperwork shows a no charge to you. Information redacted pursuant to the freedom of information act (foia), 5 u. S.

Car engine caught fire. Allstate notified pictures provided below.

While accelerating to merge into traffic, the engine suddenly lost power and died completely. I lost power steering and power brakes, making it difficult to safely maneuver the vehicle to the shoulder. There was no warning light or unusual noise prior to the stall. The vehicle has approximately 138,000 miles. This stall occurred in live traffic, creating a high risk of a rear-end collision.

I am the original owner of a 2013 Hyundai Sonata (under 90k miles). In April 2026 the engine suddenly locked up without warning. The vehicle was towed to massey Hyundai (hagerstown, MD) and a claim was submitted to Hyundai motor America for an engine replacement under Hyundai’s lifetime engine warranty program for affected 2. 4l and 2. 0l theta ii engines. I provided records I could obtain. Some oil changes were performed at home by my stepfather & several were performed by a local independent garage that has since gone out of business those records are unobtainable. I explained this & submitted all existing documentation. They denied my claim twice and closed both cases. I requested the official written denial, the date it was issued, the specific reasons for the denial, and the name and department of the individual who made the decision. Hyundai refused to provide any of that information, stating they “cannot disclose the information or documentation” and that the denial is “final. ” Hyundai has not identified any specific maintenance item I allegedly neglected, nor provided any evidence supporting their claim of “exceptional maintenance neglect. ” I have completed all Hyundai recalls and maintained the vehicle responsibly. Hyundai refuses to provide transparency or to reconsider the claim despite my documentation and original-owner status, I am requesting the bureau of consumer protection investigate Hyundai motor America for possible unfair or deceptive practices related to warranty denial & lack of disclosure. I ask that your office ask Hyundai to reopen & reevaluate my warranty claim for the theta ii engine defect based on the documentation I provided & my maintenance history as the original owner provide the written denial, the date it was issued, the specific reasons for denial & the name title & department of the decision-maker produce any evidence Hyundai relied on to conclude there was “exceptional maintenance neglect Hyundai can't substantiate its denial.

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.

Engine was replaced in 2023. In March 2026 there was a fuel line leak to include fuel misting near heat components. The vehicle was in a fender bender but Hyundai determined this did not cause the leak which eludes to this being a faulty installation of the engine replacement associated with the recall. I’ve reviewed my 2023 engine replacement invoice. I see the service kits were used to transfer parts from my old engine, but the high-pressure fuel pipe (35340-2g710) is not listed. Per Hyundai's gdi service protocols and recall 180, that pipe is a one-time-use safety component that should not be reused during an engine swap due to fire risk. Since it is leaking now, it’s clear the old pipe was reused and has failed. I'm asked for a goodwill replacement because this was a procedural error during the 2023 warranty work and was denied. This is a safety issue.

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).

I was a victim of odometer fraud I bought a car in February of this year and on my odometer it has like 144,000 miles but in my carfax it states the car has about 300,000 miles.

My 2013 Hyundai Sonata limited equipped with the theta ii 2. 4l gdi engine experienced a sudden connecting rod bearing failure while driving on the expressway in florida. At the time of failure, the vehicle had approximately 153,000 miles. The check engine light illuminated and the vehicle entered limp mode, causing significant loss of power while in motion at highway speeds. The engine and vehicle remain available for inspection upon request. Diagnostic scan confirmed p1326 — the exact code the knock sensor detection system (ksds) is designed to trigger upon detecting connecting rod bearing wear or failure. Prior to this incident, no warning lamps or symptoms were present; the failure occurred suddenly while the vehicle was being driven normally. The ksds software update was previously completed at an authorized Hyundai dealership. The vehicle has been maintained with regular oil changes and complete maintenance records are available. No engine sludge was found upon inspection at the dealership. The failure was confirmed by an authorized Hyundai dealership, which diagnosed connecting rod bearing failure consistent with the known theta ii gdi engine defect covered under the class action settlement lifetime warranty. Despite meeting all eligibility requirements — ksds update completed, p1326 confirmed, full maintenance records, no evidence of neglect — Hyundai motor America denied the warranty repair citing vehicle age and mileage exceeding 150,000 miles and 8 years. This mileage and age limitation does not apply to theta ii gdi engines under the lifetime warranty class action settlement. This failure represents a serious safety risk as the engine lost power while the vehicle was in motion on the expressway, creating a dangerous situation for the driver and other road users. The vehicle has not been inspected by police or insurance, but is available for manufacturer or NHTSA inspection.

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.

To whom it may concern: I am submitting this complaint to report ongoing safety concerns involving my 2013 Hyundai Sonata. I purchased this vehicle in 2022 through financing and paid it off in 2025. Since acquiring the vehicle, I have experienced persistent mechanical issues that I believe may pose a safety risk to myself, my child, and others on the road. The most concerning issue involves the braking system. I have had the brakes replaced and serviced multiple times, yet the brakes begin grinding again within a very short period, including an instance where the grinding returned approximately one month after replacement. Despite spending money on repairs, the problem continues to reoccur. I am concerned that there may be an underlying defect affecting the braking system that is not being properly identified or corrected through normal maintenance. In addition, the vehicle consumes an excessive amount of oil, requiring frequent monitoring and replacement between oil changes. I am concerned that this issue could potentially lead to engine failure or other dangerous mechanical problems while the vehicle is being operated. As a single mother, I rely on this vehicle daily for transportation to and from work and for caring for my family. I have experienced significant financial hardship attempting to keep the vehicle operational and safe. Despite my efforts to maintain the vehicle, these issues continue to occur. I respectfully request that the national highway traffic safety administration review this complaint and determine whether these issues may be related to known defects, recalls, investigations, or patterns reported by other owners of 2013 Hyundai Sonata vehicles. I am willing to provide maintenance records, repair invoices, mileage information, and any additional documentation that may assist in evaluating this matter. Thank you for your attention to this complaint and for your commitment to vehicle safety.

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.

While driving, vehicle slowed down abruptly and stopped. It was flashing “vehicle not safe to drive”. This happened before hen I got a new engine 2 years ago. Even with a new engine now it is happening again. I took it to Nissan moreno valley and paid $240 for diagnostic only to find out there a software update they had to do with a tablet. No work needed to be one just a software update hooked up to their system. Hyundai cooperate would not assist to over this fee. I like have crashed with this happening. The car just stops with no warning and it’s extremely dangerous how it cuts off while driving. Luckily I was on the streets not freeway.

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 a.

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 ac.

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.
