2016 Hyundai Santa Fe

The engine (2016 Hyundai Santa Fe 2.0L/2.4L Theta II GDI engine) suffered a catastrophic internal mechanical failure, specifically related to the known connecting rod bearing defect. The vehicle is currently un-driveable and is located at Serra Hyundai in Trussville, AL. The vehicle and its failed engine are available for inspection upon request. The engine suddenly failed and lost all power while driving at highway speeds in active traffic. I was forced to coast a dead vehicle across multiple lanes of traffic to the shoulder without any acceleration capability. Yes. The vehicle experienced a complete failure, cannot be restarted, and is currently parked at an authorized Hyundai dealership The vehicle is currently at an authorized Hyundai dealership awaiting a formal corporate inspection and evaluation for engine replacement approval. It has not been inspected by police or insurance. There were no long-term warning lamps, messages, or symptoms prior to the incident. The vehicle was operating normally until the exact moment of the failure, when the engine suddenly began knocking loudly, lost power, and stalled within seconds.

Fire

The vehicle is a 2016 Hyundai Santa Fe Sport. It had previously been included in an engine-fire-related recall/service campaign, and Hyundai replaced the engine between approximately October 2024 and January 2025 at about 113,000 miles. About 10,000 miles and 14 months later, the vehicle developed engine/performance problems. A Hyundai dealership service center performed about $6,500 in repairs, including installation of a new transmission, and represented that the engine and transmission had a lifetime guarantee. One day after the vehicle was returned from the dealership, the engine compartment caught fire while the vehicle was being driven. The fire rapidly escalated, the vehicle exploded/burned, and the vehicle was destroyed down to the frame. The occupants escaped, but the incident created an immediate risk of serious injury or death. The failed component appears to involve the engine, engine compartment, fuel/oil/electrical systems, transmission-related repair area, or another drivetrain component. The vehicle remains may be available for inspection depending on insurance/tow/storage status. The vehicle had recently been repaired and inspected by a Hyundai dealership service center. This incident raises concern that the recall-related engine-fire risk, replacement engine, recent dealership repairs, transmission installation, or related components may have failed and created a serious fire hazard.

WHAT FAILED: The engine — the 3.3L Lambda II GDI V6 (engine family GHYXV03.31XE per the federal emissions label) — failed catastrophically: a connecting rod penetrated the engine block. The failed engine IS available for inspection on request. It has been preserved unrepaired since the failure, the rod penetration of the block is externally visible, and the vehicle is currently at Niagara Hyundai in New York. WHAT HAPPENED / SAFETY RISK: On [XXX], I was driving at approximately 65 miles per hour on [XXX] southbound near Bath, New York, with four occupants aboard, when the engine failed suddenly and without warning — no warning lamps, messages, or symptoms preceded it. The vehicle immediately lost all motive power at highway speed. I was forced off the roadway and through brush and debris to bring the vehicle to a stop. The sudden total loss of power at highway speed created an immediate loss-of-control hazard to my occupants and to surrounding traffic. CONFIRMED BY OTHERS: The tow was dispatched through a 911 emergency call. A New York State Trooper was at the scene and observed the debris trail. The towing company's invoice (T&R Towing and Service, Call #[XXX], [XXX]) records "Break Down," winch recovery, vehicle not drivable, and the tow operator's handwritten condition description: "Motor go Boom." The vehicle is now in the possession of a Hyundai dealership (Niagara Hyundai), and Hyundai Motor America has an open case (#[XXX]); however, Hyundai has refused to inspect or diagnose the engine unless I first pay to repair unrelated damage, so the manufacturer has NOT yet inspected the failure — leaving this safety defect undiagnosed by Hyundai. RELEVANT BACKGROUND: In 2024, Hyundai issued warranty extension TXX8 (15 years / 150,000 miles) for connecting rod bearing failure in this exact engine, acknowledging the failure mode. Mileage at failure was under 100,000 miles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Crash

I filed a complaint when the first engine seized. It's a miracle we got off the road safely that day. While it was at the dealership, the engine was replaced with a used engine and covered by my extended warranty from Vroom. I believe the cost was approximately $14,000. I was told the engine had around 30,000 miles on it. I've put around 20,000 miles on this engine and the same thing happened again. This time, the engine had been knocking for a few months. When it started knocking, I took it to the dealership because the new extended warranty by Hyundai was in effect and I assumed it would be covered. Immediately, Autonation Hyundai in Savannah, GA said it would not be covered because it was a used engine. I don't understand why when the engine can be traced and the mileage known by the number on the engine. On XXX, my [XXX] granddaughter took her driving test in the vehicle. About 2 hours later, the engine seized with her driving. We were on the same road and it was about the same time of day. Once again, it was a miracle we got off the road safely. I just talked to Hyundai and we'll see what they say. From the stories I've seen, they'll do anything they can to avoid covering these engines and they get away with it. The people who get hurt the most from this are the ones who can least afford it. I'm a [XXX] widow raising my 5 grandchildren by myself and believed I was getting a good vehicle, mainly due to the report by Consumer Reports magazine. Even after the first engine failed and was replaced, I still wasn't in a financial position to get another vehicle and assumed if something happened again, it would be covered under the extended warranty Hyundai was made to provide. Obviously, that means nothing. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The engine powertrain system, specifically the internal engine lubrication, timing chain, and camshaft sensors. The vehicle's Theta II engine suffers from systemic, excessive oil consumption, which starved the engine of lubrication. This caused the timing chain to stretch and mechanically fail, and compromised the camshaft sensors. The vehicle is currently un-repaired and is available for inspection upon request at Hyundai of Downtown LA. While driving, the engine suddenly stalled and completely shut off mid-drive without warning. This caused an immediate loss of motive power and a dangerous reduction in steering and braking control while surrounded by active traffic. Operating a vehicle that randomly shuts down on public roads presents an extreme, life-threatening safety hazard to myself, my passengers, and other drivers. Furthermore, the dealership is attempting to force me to drive the vehicle for an additional 1,000 miles in this stalling, un-repaired condition to complete a corporate oil test, compounding the safety risk. The failure and safety hazard have been physically confirmed and diagnosed by an authorized dealership: Hyundai of Downtown LA (3850 S Figueroa St, Los Angeles, CA 90037). Their service department mechanically diagnosed the physical failure of the camshaft sensors, a stretched timing chain, and severe engine oil starvation. There were absolutely no dashboard warning lights, check engine lights, low oil pressure lamps, or messages prior to the engine stalling and shutting off. The vehicle computer failed to trigger any diagnostic trouble codes (DTCs) or dashboard warnings to alert me to the low oil level or the impending mechanical timing failure before the vehicle completely shut down mid-drive.

Purchased a used Santa Fe in January 2026 with 129k mile and at 131k my vehicle's CEL came on and did not function properly while operating. While driving the vehicle failed to accelerate above 25 mph when I pushed the gas. I pulled over to get out of the way of traffic and avoid any accidents. I shut the car off and sat for several minutes before restarting my vehicle. It successfully restarted and I drove home and parked it. I ran CEL diagnostic and received the code P0021. I had the vehicle towed to the local Hyundai dealer and they also pulled the same code and indicated I have an oil consumption issue explained as follows "Timing over advanced. Timing components driven by oil pressure. Inspected cylinders and borescope and found cylinder wall scoring and faulty piston rings. Radiator has crack causing coolant leak. Engine will have to be replaced to remedy oil consumption. Radiator will need to be replaced to remedy leak." resulting in over $12k of repair work. The vehicle's temperature gauge did not indicate any abnormalities nor did the oil light come on to indicate any oil consumption issues. The vehicle was driven from the dealer to my home within city limits/speed and has not replicated the acceleration issue but the CEL remains on as the repair is too costly and is more than what was paid for the vehicle.

Rod bearing failure while driving, engine made a clanking noise. Engine made a loud bang and shut off. It was difficult for the driver to get control of the vehicle and get it to the side of the road. Engine threw the rod and piston through the oil pan causing catastrophic internal damage. The oil had been changed the day prior. The company that changed the oil sent an inspector to evaluate car at the scene. He stated this is a known problem with this engine. He pulled up pictures of other cars that had the same problem, also took pictures of the car oil pan and compared the pictures, they were exactly the same. Car was towed to Hyundai dealership that is refusing to replace the engine.

While driving the vehicle at approximately at 55 MPH on a the 826, the engine suffered a sudden and catastrophic mechanical failure without warning. The vehicle lost all motive power in active traffic, creating an immediate safety hazard and nearly resulting in a rear-end collision. Upon inspection, it was determined that the engine assembly, which is a replacement unit provided by Hyundai under the Theta II Settlement, with less than 12,000 miles, suffered an internal breach. This breach allowed coolant to contaminate the lubrication system sort of a milky oil, which led to a connecting rod bearing seizure. Despite this being a repeat failure of a safety-recall component and the vehicle being covered under the Theta II Settlement Lifetime Warranty, Hyundai Motor America has denied the repair claim. I am reporting this as a safety defect because the sudden engine stall resulted in a loss of power-assisted steering and braking while the vehicle was in motion.

Beginning about a month ago, I noticed a rattle upon the engine start up that lasted for a 1-2 seconds then stopped and everything sounded normal. I thought it could be b/c of the cold weather. I went in to get a routine oil change on 03/11/2026 and they said the oil looked fine, but it was about a quart low, indicating it was burning some oil somehere. They said to check in in a few months and they would top it up if needed. I asked them about the rattle and they thought is might be from a bad (timing chain tensioner) but said I should get it checked out. I called on Friday 03/13/26 to schedule an appt at my local Hyundai Dealership on 03/17 . The night before(03/16), I was driving my vehicle and suddenly on the road, I heard a loud noise in the engine, and the power shut off, the Engine and oil light came on and I just had enough time to pull off the busy state route. My car would not start or turn over. I had it towed to the dealership and they did determine that it was a "Rod Bearing Failure" that caused the engine to sieze. I provided them evidence of my oil changes which from 10k-93k miles on my car since I have owned it. I have had the oil changed 10 times. They are saying they only allow 8k between oil changes to honor the warranty and have initially denied my claim. The service associate at the dealership said my valvetrain was 'somewhat' dirty, but nothing to where it was the cause for this issue. And since it was the Rod bearing that failed, the exact part that was recalled, he was surprised they were not even offering any good-will offer, to split the cost of the engine replacement. I have reached out to Hyundai Consumer Affairs and am waiting to hear back to see if they will be fair and work with me on this to honor the warranty issue or at least share the cost burden for this "well-known" failure in their engine.

The engine light started blinking and my car would not accelerate anymore. I took it to the mechanic immediately, who said that there was an engine recall. I contacted the dealership, but they cannot do an initial inspection for more than 2 months. It would likely take another 2-3 months after the inspection before the engine can be replaced. I called Hyundai and they confirmed that my vehicle should be covered under an extended warranty based on the service history and error code from my car (TXXI for the Theta 2 engine - knock sensor detection, code p1326). However, Hyundai will not provide any help until the vehicle is inspected by a dealership. The dealership completely refuses to look at my car as they are busy. I live on an island, so the only other Hyundai dealership is two hours away. They will not answer any of my calls. I'm expected to figure out how to commute to work alone for the next two months, but since I live in a rural area, there are no alternative transportation options. An independent mechanic confirmed and reproduced the issue. The car is unsafe to drive. The dealer will not inspect my component in a reasonable time frame, much less repair it despite the fact that it is covered under extended warranty. The car was driving normally prior to the issue, and I did not notice any problems until the engine light started blinking. I have the car available for inspection.

September 3rd, 2025, my engine failed, for the second time and left me stuck at a busy intersection, in the middle lane and can't move. The first time my engine failed (2022/same vehicle), I was about the get on the highway and it just stopped in the middle of the road right before getting onto the highway. Both times I've had to get out in traffic in order to move my vehicle. I'm causing a stop to traffic or a stop in the flow of traffic. In September when this happened, I had cops, mechanics and pedestrians stopping to help (thank goodness), but that caused a stop in the flow of traffic. Any of us could have been struck by a vehicle. It was also around 10/11pm at night There is an open recall on my vehicle and more specifically, the Theta II engine in my vehicle. It does not show when my VIN number is put in, but it's nationally known that there is an open recall and also a class action suit that was just settled in 2021 granting all customers with "Class vehicles" a lifetime extended warranty on the engines. They make it so that it's not that easy to just search and see there is a recall, but there is. My car has been at the Hyundai dealership since 9/4/25. So, yes it has been inspected by the manufacturer, and they confirmed that the diagnostic came back as positive for the recall. Yes, my check engine light would come on and off starting the end of 2024. Starting in April of 2025 I started having smoke come out of my exhaust and oil burning in days. All the while I have no puddle of oil underneath my car. I took it into Hyundai at that point, and they told me until my engine light was flashing and my car had stopped, they wouldn't be able to do anything in regard to the engine. Now my car has been there, I've provided service receipts that show proof of regular maintenance, I have the KSDS system installed, and they are denying my claim to replace my engine.

Six weeks ago the alternator and battery had also been replaced. My Hyundai Santa Fe Sport turbo engine, exhibited a persistent rubber-like odor for approximately three weeks after the latest maintenance. During this period, the push-start button intermittently failed, requiring multiple attempts to engage, and the vehicle experienced noticeable shaking. After being parked, smoke began to emerge from under the hood, followed by visible flames. Within roughly 3-5mins minutes, the vehicle was completely engulfed in fire and blew up 6 times. Notably, the car had undergone significant repairs in the past year, including an engine replacement, starter, OEM parts, O2 sensors, brakes, valve cover gasket, new tires, and routine oil changes.

There was no low oil indicator light, no smoke, and no oil on the garage floor. My wife was driving the vehicle on I-285 in Atlanta, returning from the ATL airport, when the vehicle began to lose power and started jerking and surging; the check engine light began flashing. She had to take surface streets to get home because the loss of power made the vehicle unsafe to drive on the freeway. When she arrived home, I checked the engine oil dipstick and it was completely dry. I took the vehicle to the garage that performs my oil changes, and they mentioned this is an ongoing issue with Hyundai—the vehicle is burning oil. The low oil level caused the knock sensor to trigger, which in turn caused the check engine light to flash and reduced power in an attempt to protect the engine. I never received any notification regarding a recall for this issue, and now my motor is more than likely damaged since I can still hear knocking when the engine runs at higher RPMs. My vehicle has over 100K miles, and I have never had an issue with it until now.

However, the dealer (Castle Hyundai of Downers Grove, IL) said because my engine failed due to timing chain failure and not connecting rod failure, Hyundai would not honor the extended warranty. That infuriates me! Hyundai should honor the extended warranty because their engine failed and it wasn't my fault. They know they have an engine problem but because my engine didn't fail exactly the way they projected it would fail, I'm [XXX] of using my car.

My safety was impacted severely as if the cars around did not hit the way they did, I believe I could have died. It is extremely concerning that they did not go off when such large amounts of damage were done. In addition, there have been over 50,000 recalls done for air bags not working in this exact vehicle. In addition, the vehicle is being checked in the next day for additional damages and they will confirm the air bag issues. Police as well as insurance providers were shocked that the air bags did not deploy in such a severe case. No warning messages or lamps were on when the accident occurred or before. This is extremely concerning and I now fear for my safety even further if I were to purchase this vehicle again. It is a terrifying thought that I could have died due to a car malfunction.

My 2016 Hyundai Santa Fe lost all power, shutting off and stopping abruptly in the middle of the road with no warning lights or “limp mode” being set off requiring my partner and I to push it into someone’s driveway with our two children in the car to get them to safety. We took the vehicle to a mechanic shop where we were told that to engine was seized and needed to be fully replaced with an initial quote starting at 8 thousand dollars for a replacement engine. I contacted my local Hyundai dealership and was told over the phone that the vehicle would be covered under Hyundai service bulletin TXX8 that was issued last year due to ongoing issues with this engine (3.3l V6 Lambda II). We paid to have the vehicle towed to this dealership only to be told that the warranty would not be honored due to a lack of maintenance records. I was able to provide Hyundai with all maintenance records from my ownership as well as records on the CarFax report. They rejected the claim again stating that due to a lack of records not from my ownership they won’t cover it. After looking at the records I had access to again in critical detail I was able to find records that Hyundai missed, but they are unwilling to reevaluate the claim without me providing what they call additional records. I have contacted Hyundai, to try and resolve the issue and have gotten no resolution. The Prior Authorization team has stated that I have “adequate records” but still insist on denying the claim. The dealer has quoted me $12,000 for the repair that the warranty should be covering due to the engine not being manufactured in full anymore due to the issues that have come from it. The dealership (and private mechanic) would have to order individual pieces of the engine to build it themselves on site. If this engine is a big enough problem that Hyundai cannot provide a full engine replacement at market value then it should not be operating on the road at all.

Subject: Engine Failure Due to Bearing Defect – No KSDS Recall Notification Vehicle: 2016 Hyundai Santa Fe Sport VIN: [XXX] Date of Purchase: April 2016 Complaint Summary: I am filing this complaint regarding my 2016 Hyundai Santa Fe Sport, which experienced catastrophic engine failure due to the known Theta II GDI engine bearing defect. Hyundai has an active class action settlement covering this defect, which requires owners to install the Knock Sensor Detection System (KSDS) update to be eligible for free repairs or the lifetime warranty. Despite owning my vehicle since April 2016 and holding clear title in my name for over 6 years, I never received any notice or communication about this required software update. Hyundai’s records still list the prior owner, Hertz, even though I have maintained valid registration and insurance in my name since the purchase. This lack of notice prevented me from having the KSDS update installed before the engine failed. I understand this defect does not show as an open safety recall on the NHTSA database because Hyundai classified it as a Product Improvement Campaign under the class action settlement. This does not change the fact that it is a known safety hazard and Hyundai failed to properly notify me, which denied me the chance to protect myself and my vehicle. I believe this is a major safety concern because the engine can stall or catch fire without warning. I am requesting that NHTSA hold Hyundai accountable for failing to properly notify current owners and ensure compliance with the class action settlement. Desired Resolution: Require Hyundai to honor the warranty and cover my engine replacement in full. Investigate whether Hyundai is failing to properly notify owners about this critical software update. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle lost power, and the engine started to make a knocking noise, and the check engine light came on. I plugged in the obd2 scanner and the p1326 code came out. It was a knock sensor that needed to be replaced. I replaced the sensor that the issue got worse. I looked up online about this issue and then I found a video of that explained the incident. The manufacture of the crank at the factory did not properly clean the holes of the oil passages. When they machined it, all the files they don't clean them good enough, so they go to one side and plug up the oil passages and it doesn't get oil. we were on the highway when this issue started and it lost power. The problem has not been solved because the Hyundai dealer and the corporate office did not want to help me with this issue. They claim that my title is salvaged but I contacted the DMV, and they confirmed that my title is clean and there is no issue. The second time they said the vehicle was used as a rental and that automatically disqualifies the vehicle's warranty. The vehicle has not been inspected. No warning at all until the day it happened. I just purchased this vehicle seven months ago for seven thousand dollars and this happened.

Dear NHTSA, My 2016 Hyundai Santa Fe Sport (VIN: [XXX] , 2.0L Theta II, 64,000 miles) suffered engine failure with knocking and power loss, matching NHTSA Recall #20V-746 (Hyundai #198). This defect risks stalling or fire, threatening my safety and others’. Hyundai Motor America and Hyundai of Tacoma (Tacoma, WA) refused repair, citing the rebuilt title, despite the factory defect. Recall #20V-746 addresses Theta II bearing wear. My vehicle’s symptoms align, yet the dealer denied service, claiming the title voids eligibility. Hyundai’s April 2025 email noted three unrelated recalls (turbo oil pipe, ECM update, hood latch) were completed but ignored #20V-746, redirecting me to the dealer without addressing the engine or title issue. I’ve called Hyundai (1-800-633-5151) and emailed multiple times since March 2025, receiving only generic responses. The dealer’s refusal and Hyundai’s inaction leave the vehicle inoperable, posing a ongoing safety hazard on the road. The rebuilt title should not exempt a factory defect tied to a safety recall. The low mileage (64,000) supports my claim. I haven’t obtained a diagnostic report but am willing to pay for one (~$100–$200) if required. Hyundai’s refusal to honor #20V-746 violates safety obligations. Please investigate Hyundai’s denial, confirm if the Knock Sensor Detection System was installed, and clarify if a rebuilt title excludes eligibility. I seek engine replacement per the recall or a clear explanation. This issue has caused significant financial and safety concerns, and I urge swift action. Contact me at [XXX]or [XXX] Sincerely, [XXX] [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Hyundai Motor America (Hyundai) is recalling certain 2016-2018 Santa Fe, 2017-2018 Santa Fe Sport, 2019 Santa Fe XL, and 2014-2015 Tucson vehicles. The Anti-Lock Brake System (ABS) module could malfunction and cause an electrical short, which could result in an engine compartment fire.

Risk: An engine compartment fire while parked or driving can increase the risk of injury.

Remedy: Owners are advised to park outside and away from structures until the recall repair is complete. Dealers will replace the ABS multi-fuse, as necessary, free of charge. Owner notification letters were mailed May 31, 2022. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 218.

Hyundai Motor America (Hyundai) is recalling certain 2013-2017 Santa Fe and Santa Fe Sport vehicles. In the affected vehicles, the secondary hood latch actuating cable may corrode and bind, causing the secondary hood latch to remain in the unlatched position when the hood is closed.

Risk: If the hood is not securely closed or the primary latch is inadvertently released and the secondary latch is not engaged, the hood could unexpectedly open while driving, increasing the risk of a vehicle crash.

Remedy: Hyundai will notify owners, and dealers will replace the secondary latch cable, free of charge. The recall began on August 4, 2017. Owner's may contact Hyundai customer service at 1-855-671-3059. Hyundai's number for the recall is 163.

Hyundai Motor America (Hyundai) is recalling certain model year 2016-2017 Santa Fe vehicles manufactured September 1, 2015 to February 12, 2016.
