general problems of the 2016 Hyundai Santa Fe - part 1

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.

I turned off the car and went inside the house. I was outside and could smell smoke. I walked to the front of the house and saw my neighbor who was calling 911 due to flames from my engine. The flames reached the yard and my garage where minor damage occurred. The vehicle was completely engulfed in flames before the fire department extinguished it.

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.

The contact owns a 2016 Hyundai Santa Fe sport. While driving at an undisclosed speed, there was an abnormal odor coming from the vehicle. The contact stated that the engine was consuming an excessive amount of engine oil. The vehicle was taken to the dealer; however, no cause for the failure was found. The contact stated that on a separate occasion, while driving at an undisclosed speed, there was an abnormal sound coming from the engine. The vehicle was pulled over to the side of the road; and the check engine warning light illuminated. A handheld scanner was used to retrieve dtc: p1326 (ksds – connecting rod bearings failure). The vehicle was towed to the residence, and then towed to the dealer. The dealer diagnosed the vehicle and informed the contact that the rod bearings had failed, causing engine failure. The dealer notified the manufacturer of the failure; however, the manufacturer declined to repair the vehicle. The manufacturer informed the contact that the prior owner had submitted a complaint regarding the failure in January of 2024. The vehicle remained at the dealer unrepaired. The failure mileage was approximately 132,000.

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.

2916 Hyundai Santa Fe sport has an open recall of 953 for engine bearings knocking. It has been inspected. Yes, safety was put at risk, motor could lock up while driving causing a wreck. Yes, tim shorts Hyundai did confirm the engine was knocking. No lights were on in the vehicle. Was started sitting in the drive way, when the engine started knocking.

The contact owns a 2016 Hyundai Santa Fe. The contact stated that while driving 60 mph and attempting to depress the accelerator pedal, the vehicle decelerated and failed to respond as intended. The contact coasted to the right side of the road, turned off the vehicle, and the vehicle failed to start. Neither an independent mechanic nor a dealer was contacted. The vehicle was towed to an independent mechanic; however, the vehicle was not diagnosed. The contact was informed that the vehicle was scheduled to be diagnosed. The vehicle was not repaired. The contact stated that the failure had occurred on four occasions. The manufacturer was not notified of the failure. The approximate failure mileage was 150,000.

The contact owns a 2016 Hyundai Santa Fe sport. The contact stated that while driving uphill, the vehicle failed to accelerate above 10 mph. There was a burning odor coming from the vehicle with the check engine warning light illuminated. The contact stated that the engine had previously been replaced, but the failure persisted. The vehicle was towed to the dealer, who determined that the knock sensor needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 130,000.

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.

Engine siezed, causing me to have to tow my vehicle. I was moved in the military to germany in 2019, I had to have no open recalls on the car before I shipped it overseas. I completed a recall on the 5th of January 2019. On the 10th of January, Hyundai activated another recall on the vehicle. I was unaware of this recall and shipped my vehicle to germany on the 16th of January 2016. The car returned from germany in September of 2023. I had zero issues with this vehicle while I was over there, no check engine lights, no warning lights, nothing. I always changed the oil when told to do so, and when I returned from germany it was the same thing, no issues and always completed oil changes when it was needed. I had no idea of the recall, Hyundai was sending it to an address I no longer lived at. I had no reason to take my vehicle to Hyundai to check for recalls. On [xxx], my vehicle engine stopped working at 84622 miles, and Hyundai said that it would be covered under warranty, but because I did not complete the recall that was activated on the 10th of January 2019, they denied the warranty and now my car is worthless. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My engine failed at 113,000 miles. It just sounded like a diesel truck when I started it one day. There were no warning messages at all. It did not have any power above 45 mph. I took it to a Hyundai dealer and showed him the extended warranty letter I received from Hyundai. The letter said my specific engine should qualify for an extended warranty. 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 screwed out of using my car. It also meant I had to purchase a new car which obviously wasn't a Hyundai. I hope you can push Hyundai to provide me financial relief or at least expand the engine warranty for others.

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.

My engine seized at approximately 80mph on the interstate [xxx] ). The engine light came on only after I lost power. I only avoided a multiple car accident due to quick reaction and taking an exit ramp. Police came to my stalled vehicle and helped my push it off a major road to a nearby parking lot. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

As we were driving down the interstate we began to see smoke coming out our vents and after a few seconds saw flames coming from the passenger side of car. We quickly tried to pull over but brakes weren’t working. Safely pulled into grass median. Luckily we were able to quickly exit through the driver door. After about 30 seconds the car was engulfed in flames.

I need to replace engine block assembly and the following codes p1326 c1207 c1210 c1211 c1206 c1208.

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.

This is my 2nd engine on my 2016 Santa Fe sport. My car has 190,000 miles and had a catastrophic engine failure, it’s been at the dealership for 2 months. Hyundai said my lifetime warranty on my engine is not covered cause I had a misfire in the #4 cylinder with less than 2,000 miles on the spark plugs. Hyundai warranty department only spoke to the dealership directly and had me speak to a case manager (which did nothing, they never even talked to the warranty department only the dealership) so in December I dropped my car off, it took over 2 weeks to take pictures and send them in to Hyundai warranty department, a week later Hyundai asked the dealership to further take the engine apart and get pictures of the rocker’s. The dealership is down to 2 technicians and said they will get to it when they can (remember I’m without a car and waiting for approval for my engine so they can get me in a rental car while my engine gets replaced). Over 3 week later the dealership finally sends the pictures in of the rocker’s, I know cause I called and asked the dealership. I then asked why does the warranty department need pictures of the rockers for my engine failure (misfire in 4th cylinder) and they said to check for sludge. They also pointed out my engine isn’t bad and don’t have sludge so the warranty department should approve my engine replacement. A week later my case manager called and said that they will only approve 50% and I said no there a lifetime warranty and I’m the original owner, so they went up to 65%. I feel betrayed by the dealership, case manager and Hyundai warranty department for not honoring the engine replacement knowing there’s a class action law suit due for failing rod bearings which they said wasn’t the issue. How would they know? the rod bearings are on the bottom of the motor and if they took it apart they would see that was the cause, but they say they don’t warranty misfire’s yet tens of thousands of Hyundai buyers are having same problems. Help.

The contact owns a 2016 Hyundai Santa Fe sport. The contact stated that the engine and oil lights illuminated whenever the brake pedal was depressed. The vehicle was taken to the local dealer where it was diagnosed and determined that the cause of the failure was due to the engine. The dealer informed the contact that the pistons were not covered, and the engine was consuming an excessive amount of oil. The dealer instructed the contact to continue to drive for 1,000 miles and come back to the dealer for an evaluation. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was approximately 77,000.

The contact's husband owns a 2016 Hyundai Santa Fe. The contact stated that while driving at various speeds, the vehicle failed to accelerate upon depression of the accelerator pedal. The check engine warning light appeared on the instrument panel during the failure. Despite the vehicle operating in limp mode, the vehicle was taken to an independent mechanic where an oil change was performed. The mechanic warned after the service was performed that there may be an ongoing failure with the engine. Several days later, the contact stated that while in stop and go traffic, the vehicle stalled with the check engine warning light illuminated. Due to the failure, the vehicle was towed to an independent mechanic where a diagnostic test was performed; and the contact was informed that the failure might be related to the cam shaft. The contact had the vehicle towed to a dealer and informed that the failure was probably related to the high-pressure fuel pump. The high-pressure fuel pump was replaced; however, the failure persisted. The contact was then informed by the dealer that the engine needed to be replaced. The manufacturer was not notified of the failure. The vehicle remained with the dealer unrepaired. The failure mileage was approximately 200,000.

Engine has serious recall that I was not made aware of during purchase. My car has been burning oil and the engine has been on. I've taken out to several local mechanics who said "these model Hyundai's burn oil once they are over 100,000 miles" and that I would just need more frequent oil changes. I was also told the engine light was either an old code being thrown, or the pump valve, but nothing to worry about because it really only effects gas milage. My engine went out and I had to get it towed to another mechanic, who upon seeing the car, knew it had an engine recall and could hear a distinctive knock in the engine due to a failing rod bearing. Upon Hyundai's request, we towed it to a dealership to have them inspect it. They agree it's the engine that's bad, but since a "knock sensor" was never installed by the previous owner, they say they are not liable to cover the repair, and that since the recall is "public knowledge", it was my responsibility to find out. If you go onto the NHTSA. Gov website, and type in my VIN number, the information says "0 unrepaired recalls", therefore making it impossible for me to have known about the recall without Hyundai letting me know, which they didn't.

Four weeks ago, I noticed my 2016 Santa Fe was not blowing any heated air into the cabin. A/c would come out fine, but room temperature air at best even when thermostat set to max. I took it in for diagnosis at a local mechanic who informed me that coolant was leaking out of the engine block and into the exhaust. I took the car to the dealership who informed me that the engline block itself had somehow gotten a tear in its side. No telling how the damage occurred, yet the warranty company (costguard) in acquisition of my powertrain policy rejected the claim because (without ever personally inspecting the vehicle) there "was no discrepency as to how the damage occurred. " every mechanic at the dealership who has seen my car disputes their answer. I have been up to date on all maintenance on my vehicle throughout my ownership and have receipts, but cannot add them as they are all in my glovebox and the car is still at the shop. While I find it personally ridiculous that a warranty company would deny this, it is important for me as well to add to the list of engine complaints about this car. Likely the damage to the engine block has also been the cause of reduced mileage I have experienced lately.

Driving on a slight upgrade, lost power and smoke started to come out of the vents and from under the hood. Had no brakes and by the time we were able to drift to a stop, the engine compartment was on fire. There was no warning lights. Witnesses saw fire under the car while we were coming to a stop. The car and all contents were totally consumed. Following some research on NHTSA VIN decoder we found that this car has the same engine (gdi theta ii) that has been involved in many fires and is involved in class action suits. Even though this car has the same engine, it was never recalled. That may indicate that there are other cars out there that may have the same problem but have not been informed.

The contact owns a 2016 Hyundai Santa Fe sport. The contact stated that while her husband driving at an undisclosed speed, the vehicle inadvertently lost motive power. The driver was unable to pull over to the shoulder of the roadway. The vehicle failed to restart. There was no warning light illuminated. The vehicle was towed to the dealer, who diagnosed a failure with the engine. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA hotline for assistance. The failure mileage was unknown.

What component or system failed or malfunctioned, and is it available for inspection upon request? engine failure due to oil consumption how was your safety or the safety of others put at risk? car attempted to die on a highway, this could have been dangerous had I been in the outside 'fast' lane when it struggled. Has the problem been reproduced or confirmed by a dealer or independent service center? yes, the dealer has confirmed the engine needs a full replacement has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? no, only the dealers service center has inspected the vehicle were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? yes. There was a blink engine light shortly before the car engine died. However, there was no indication the oil was low in the engine. The oil light did not come on.

We were driving through our neighborhood at about 25 mph and we heard a slight knocking noise and then the engine shut off, no warnings or lights, just engine failure. The electronics worked, but car wouldn’t start. Had it towed to a local mechanic where he said the engine is seized. We were thankful this happened at a low speed in a safe place, can’t imagine how awful it would have been if we’d been going 75 mph down the 4 lane interstate. Of note, we have always kept the vehicle current on oil changes/maintenance. Prior to this, the car drove great! never had any issues that would point to impending trouble.

Was driving on a 5 hour car ride at 5pm on August 16th and was going up a hill, the vehicle quickly lost all power and the engine light lit. I was able to pull the car to the side of the road with the momentum that the car already had, but was not able to get the car to a safe space (its about 6 inches from an exit ramp lane), as the car would not drive. Once I got the car to the side of the road, I checked the engine and did not see any excessive heating or anything out of the ordinary. I tried to restart the car and the check engine light is lit and the battery system for the car turns on but the car will not start or try to turn over the engine. The car is currently sitting on the side of the road. My wife and my dog were in the car and we had to quickly move to a safer place away from the 70 mph traffic. Calling a tow truck tomorrow to take it to a dealership. It was a little scary that the engine power cut out like that without giving an engine light notice in advance or giving time for me to navigate to a more safe space to park it.

Engine shuts off and slows down while driving.
