general problems of the 2017 Hyundai Santa Fe - part 1

We are driving on the highway and the engine just stop working but all lights are still working. I am trying to put gas but it seemed that the engine completely shuts off dangerously without warning. This put my family at risk because there were a lot of big trucks beside us. Theta ii 2. 0l turbo engine just stalled I believe this has been around . Can you please help us.

My 2017 Hyundai Santa Fe sport has never had any issues until last Friday when I took my car to the dealership for regular maintenance (oil change, tire rotation) as I always do. They also performed a software update for recall campaign 9c2. Every day since, when first starting the car after it’s been resting for a while, I’ve experienced a jerky transmission and rough shifting for a first couple minutes of driving. Hyundai has acknowledged they are aware of this issue related to the campaign and the dealership said they’ve had many customers complaining of the same problem following the recall update. However, Hyundai has offered no resolution, other than recommending the car warm up for 13 minutes after starting. Hyundai needs to correct the issue they caused, as my car was perfectly fine before it was serviced and now it’s not performing properly.

Air compressor and compression failed engine diagnostic test. Vehicle had high oil and gas consumption.

Hi, my name is [xxx], I bought used hyndai santafe sport 2017 from dealership in 2020. It had around 47,000 miles on it, intitially it was running fine but after driving 2 years I discovered that engine is burning oil and after the oil change right after 1000 miles I had to add a quart of oil and it was like every two weeks. I had many srevices from dealership and other auto mechanic stores but it didn't improved. I had no choice but to keep driving the card on xxx th the engine crashed with out any sign on dashboard. There was slight noise and it increase by the way car was parked on the side road from highway. The car was towed to my local mechanic and confirmed that engine is crashed. After I had to towed to dealership and I am still waiting for their response. Now we have put 43,000 miles in 6 years (91,000) total mileage. I had bought the waranty from dealership by $ 2500 which expired in 2025 currently no warranty. My question here is that the car is still under 100,000 and engine failed. What if the dealership refuse to replace the engine. What are my leagal rights. Thanks [xxx] [xxx] [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I was told my top side of my engine failed, and they only cover bottom side engine failure. As well as pieces was missing. When I looked at the video it showed that my screws has fell off vs removed.

Campaign 9c2 was installed on this vehicle and the now the vehicle is a danger to drive. My wife refuses to drive it as it bucks and jerks as well as the gas mileage has decreased from 35 highway to 28 highway. The fuel trims are way off on cold starts and the transmission now searches for the correct gear. Shifting back and forth. Just a slight touch of the accelerator and the car seems to jump forward which makes stop and go driving almost impossible.

I was driving on a main road at 55-60 mph with my daughter and grandchildren in the car and had a sudden loss of power. I was almost hit from behind. The check engine light started blinking. And the car went into limp mode. I had to limp it to the nearest place to safely get off the road so as not to put my family in any other danger. There is not enough shoulder on the road to pull over safely. It was very stressful. Was able to get it in someone's driveway and then eventually towed to auburn,NY Hyundai/Chevrolet where it is currently. It would not turn over to start again. It does have battery power. I am waiting to hear from the service techs as to what they think is wrong. They advised me that there is a $199 per hour diagnostic fee. I also told them that we noticed metal flakes in the oil when we checked it. I feel I should mention that the vehicle went into limp mode a few weeks ago also and the dealership told me the knock sensor was bad. I had that replaced at that time.

The contact owns a 2017 Hyundai Santa Fe sport. The contact stated that while driving approximately 35 mph a loud noise and smoke was suddenly present coming from under the hood of the vehicle and the engine stalled. The vehicle was towed back to the home. The contact indicated that during the failure no warning messages or lights had displayed. The cause of the failure was not yet determined. The local dealer and manufacturer were not yet contacted. The VIN was not available. The failure mileage was 83,000.

After the ecm recall for a software update the car would not run correctly. It jerks and and runs rough. It almost stalls when you put your foot on the gas. I took it back to the dealer and they can not get the problem to duplicate. Noone else has looked at the problem. There were never any problems with the care until the recall. The problem occurred the day I brought the car home from the ecm update.

The engine burns oil fast. You have to replace oil on a regular bases. The car also looses fluids fast as well. This causing the engine to over heat. This causes the cylinder to head blow.

Vehicle serviced on 5/7/2026 for Hyundai service campaign 9c2 immediately after noticed car was not driving as it had been prior to this update, sluggish acceleration on start, chugging and then rapid sudden acceleration. Returned to service dept may19. Diagnostics revealed no issues, problem persisted. Returned to service dept. May22. Informed Hyundai was looking into this issue related to the 9c2 update and awaiting a new update to fix the problem. As of todayjune15 there has been no action to remedy the problem. Do not feel safe driving a vehicle that hesitates when starting to drive and then accelerates roughly. This has happened consistently upon cold start up thus far but concerned it may happen while in traffic or at other times and result in an accident.

After the installation of the service campaign 9c2 engine update, the car now seems to surge or rev up briefly at lower speeds like it can't find the right gear or is trying to briefly accelerate. It doesn't seem to be as noticeable at highway speeds, but in residential or low speeds, it's very noticeable and a little unsettling as the car feels like it wants to briefly lunge forward. No lights are on the dash and there is no indication of any malfunction, but it did not behave this way prior to the 9c2 engine program update. I waited for a couple weeks before contacting Hyundai corporate about this issue because I was hoping maybe the transmission or engine was relearning after a battery disconnection, but it has not gone away.

No power till car warms up for 5 minutes. It will be jerky on highway. The gas mileage is going down drastically, I was doing 32 miles to gallon and now it's 22mpg. All this is after the recall we just had performed. I have no power trying to avoid accidents, taking off from stopping. Car smells weird now.

Hair line creak in oil pan. Creak has caused excessive oil consumption and leaks on pavement. Issue was confirmed by antwerpen Hyundai and oil pan was replaced on 4/28/2026 at a cost of $520. 00. As above reported to dealer. Problem started, 1st. Noticed about 9 to 12 months.

While driving home on the highway from our sons hockey game at about 8:30 pm we were going about 60 mph when the car made a noise and began smoking and as we were trying to pull over on the side of the highway noticed by the reflection of a passing car that the engine on our vehicle was on fire under the vehicle. We had to evacuate the vehicle quickly and get our children out on the side of a busy highway with fire showing under the front end of the car.

On 4/17/26 mcdonalds Hyundai of [xxx] , dealership performed an ecu update for theta ii emissions logic improvement (Hyundai campaign number 9c2). Ever since that time the vehicle has been lurching during acceleration. This happens particularly when the vehicle has been sitting for several hours. I reported this to the dealership on 4/28/26 (scott, service manager) and to Hyundai on 4/29/26 (Hyundai case management #: 42610495). I noted to Hyundai that this same/similar problem has been reported by other owners ( see [xxx] ) information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Seem like there was a recall on the 3. 3l engines on the Hyundai Santa Fe starting January 26, 2017, for engine related knocking noise. My VIN is [xxx] according to the manufacturing plate it was made in korea released on January 04, 2017. I realize it is a 22-day window on the recall but after an oil change the motor has started knocking the oil is the right viscosity, full to capacity, and oil filter changed. I drove 200 miles after an oil change then the motor started knocking. Is there a certain stamp on the cam shafts to verify which of the 420 vehicles are affected by this recall? information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I am submitting a complaint regarding a turbocharger failure on my 2017 Hyundai Santa Fe VIN [xxx] . The vehicle experienced turbocharger-related failure symptoms including loss of power and drivability concerns. This created a potentially dangerous situation because the vehicle was unable to accelerate normally and could have caused difficulty merging into traffic or maintaining safe roadway speeds. I contacted Hyundai motor America requesting assistance with repair coverage. Hyundai denied assistance solely because the vehicle was outside the warranty period by time and mileage, despite the seriousness of the failure. I am concerned this issue may be related to broader engine or oil-related defects reported in Hyundai vehicles, including possible oil starvation, excessive oil consumption, or internal engine contamination that could contribute to turbocharger damage or failure. I believe this condition may represent a safety-related defect because sudden power loss during operation increases the risk of a crash. I request that NHTSA review this issue and investigate whether similar turbocharger or related engine failures are occurring in 2017 Hyundai Santa Fe vehicles. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

See attached document for complaint.

My engine just died wont start has 121099 and Hyundai wont fix it.

My abs lights the triangle with the ! in the middle goes in and off the down hill control light and the sweet control light all go on when the abs light goes on my oil was completely dry had to add two quarts while the engine was ticking when started and when accelerating it was making a clicking noise I still had 3000 miles before needed an oil change but like I said it was bone dry and then the drivers seat was going back and not wanting to come back up I’ve only had the car 42 days and it’s having all kinds of problems.

Engine seized up on the interstate. Vehicle has ~97,000 miles. Towed to dealership. Dealership wanted $8,000+ to replace engine. Hyundai refused to honor their warranty of 15 years/150,000 miles. Remains at the dealership, unrepaired.

Reporting a serious safety concern involving my 2017 Hyundai Santa Fe sport with the theta ii engine. While driving on the highway, my vehicle suddenly lost power without warning. The vehicle became unsafe to drive and I had to pull over and have it towed. There was no warning light before the failure. The vehicle has been regularly maintained. Hyundai later stated there was internal engine damage. My vehicle also shows an open engine-related recall/campaign since November 2025. I have found many similar complaints from other Hyundai owners describing sudden loss of power, excessive oil consumption, and engine problems involving the theta ii engine. I contacted Hyundai motor America and provided documentation and videos, but I have not received a meaningful response. I am concerned this issue may represent a serious safety defect because the sudden loss of power occurred while driving on a highway.

Engine. It happened while I was driving. No it wasnt reproduced or confirmed by a dealer, but have been told by a couple and also me seeing that the engine wasnt able to manually be cranked at all. No inspection was done by manufacturr, police, or insurance, because it didnt cause a accident. Just engine light which have been reported to the dealership and was toled they couldnt fix it, but that was just staying on all the time for quite some time. No finally I would like to see if this can be investigated on to be a recall since the original miles are only about 68000 and shouldnt have these problem at this low mileage.

I purchase the 2017 Santa Fe sport in October of 2023 with just short of 80k miles. It was in great condition and had no issues. I have maintained it according to Hyundai specification and regular on schedule oil changes with recommended 5w-20 full synthetic. At approximately 100k miles, I experienced an oil pressure light on the dash, when checked, the engine was approximately 2 quarts low. From this point on, the engine started consuming oil at an increasing rate all while I maintained regular maintenance. First, 1 quart a month, or about 1200 to 1500 miles, then to 1 quart every 2 weeks or 800 miles. I maintained weekly checks on the oil level and on the evening of 3/24/2026, I had added a quart, bringing the level to the midway point between the high and low dipstick markings. On the afternoon of 3/24/26 while driving on the highway in heavy, but at speed limit, traffic on the highway, I experienced a loss of power and a check engine light. I was able to exit the highway but the car started to run very rough and unable to idle. Luckily, there was no traffic approaching when I turned off the exit and made a left into parking lot to shut off the vehicle. I will be having it towed to a dealership in the next few days for their analysis.

These vehicles are not suitable to be on the road, and you NHTSA and Hyundai are doing nothing about it. These vehicles are eating oil, a quart every 200 miles. My daughter(college) can't even go on a short road trip to another city without adding oil. The engines in these crap cars are blowing up left & right. There are numerous facebook page groups for these and sister kia vehicles with the same 2. 4 engines. Thousands upon thousands of posts about engine oil and engines blowing up, no one doing anything about it. My daughter's car is beautiful, but worth nothing due to this issue, so we are out thousands of dollars on this. We are about to go to war with Hyundai on this and I'm sure we'll get nowhere. If we're lucky, they'll install a rebuilt engine. . . But it"s the same crap engine!!!!!!! so we are all back to square one and NHTSA is doing nothing. This is a well known flaw for years now.

After performing regular oil changes, and even a new fuel pump sensor, I experienced an issue. Last oil change was within the past two weeks. Driving home from the mountains, I heard a knocking sound from the engine bay. I narrowed it down to all gears above 2500rpm, increasing knocking with rpm speed. I took it easy on the engine, mostly coasting down the mountain. Suddenly during acceleration on an uphill, a pop sounded, and copious white smoke started coming from the engine bay. I pulled over despite having no power brakes but I was fortunate to be near an off ramp in a rural area. Trying to troubleshoot roadside, I noticed fluid on the tie rod, but I wasnt able to determine what kind of fluid it was. When I try to start the car, there is one single click, the engine wont even attempt to turn over. Oil, battery and check engine lights are all on. After towing, I found that the fluid leaking from the vehicle is oil. The vehicle is currently at a transmission shop, but from my research, this isnt a transmission issue but a blown rod bearing the Hyundai engines are know for. I will be contacting a dealership to see if they will at least confirm my diagnosis.

My vehicle had oil consumption problems that were fixed with a new replacement engine now my catalytic converter is going bad due to engine oil consumption problems and the dealer I deal with is refusing to help with this issue. There is only around 50k miles on the new engine. I would greatly appreciate your help with this thank you!.

My wife's 2017 Hyundai Santa Fe limited experienced a sudden crack in the engine and lost oil without any warning signs. There were no warning lights, no check engine light, and no unusual noise before the engice crack. A certified independent mechanic inspected the vehicle and confirmed the engine has no oil, whick it did a couple days before when I checked the oil and topped it off, which is the same issue described in Hyundai’s known engine safety recalls. I was never notified of any safety campaigns or recalls. I am not the first owner, so the required recall inspections and updates were never completed on this vehicle before I bought it. The sudden engine crack and loss of oil created a serious safety risk, especially because there was no warning before it happened and it almost left our family stranded two hours from home. This failure matches the symptoms described in Hyundai’s theta ii engine defect investigations. While at the mechanic shop, we were quoted $10,000 to get a new remanufactured engine put into this car. I certainly (and I know most families) don't have $10k sitting around waiting to be used for car repairs. I am requesting that NHTSA investigate whether this vehicle should be included in the affected group, and whether this engine failure is part of the broader safety defect already identified in many Hyundai engines from the same model years. This vehicle is currently parked in our yard waiting to be repaired or sold. I would prefer it be repaired by Hyundai since one of the car plants is only 1 hour from our house. I was unaware of the current safety recall until I read it today.

The contact owns a 2017 Hyundai santa. The contact stated that while driving at approximately 55 mph, the vehicle stalled and hesitated to accelerate while the accelerator pedal was depressed. The check engine and check engine oil warning lights illuminated. The vehicle was taken to a local o'reilly's, where it was diagnosed with ignition coil #3 misfire. The vehicle was not repaired. The vehicle was towed to an independent mechanic, where it was diagnosed and determined that the engine needed to be replaced due to severe engine oil consumption. The vehicle was then to a local dealer, where it was diagnosed with abnormal engine oil consumption, and the dealer determined that the engine needed to be replaced. The vehicle was not repaired. The contact stated that the vehicle required an engine oil refill 800-1,000 miles before an engine oil change was due. The contact related the failure to several unknown Hyundai tsbs. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 87,000.

Following the completion of an official emissions recall software upgrade at fitzgerald auto mall countryside, clearwater florida, my 2017 Hyundai Santa Fe sport (52,000 miles) now suffers from a severe loss of motive power and erratic transmission shifting/jerking during cold starts throughout day. The vehicle continues to hesitate during cold starts, making it impossible to safely accelerate from a stop into incoming traffic. I returned to dealership on 5/29/26 to address continued driving issues. The servicing dealership states they don't have a software fix and offer no mechanical fix. The dealership states they received an internal memo from Hyundai corporate which instructed the dealership to tell affected owners to idle the vehicle for 1-3 minutes before driving to allow system adjustments. Forcing a consumer to wait out a dangerous powertrain defect in a running vehicle to avoid a roadway acceleration/loss accident is an unacceptable safety hazard. The manufacturers recall update has actively compromised the safe operation and motive control of this vehicle.

Immediately following the implementation of service campaign 9c2 and TSB 25-01-087h - ecu update for theta ii emissions logic improvement, the vehicle exhibits poor drivability (staggering/missing/hesitation) until the engine warms up. This is most noticeable just prior to the shift from first to second gear.

The contact owns a 2017 Hyundai Santa Fe. The contact stated that the vehicle was using an excessive amount of oil. There were no warning lights illuminated. There was no indication of a leak. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The dealer informed the contact the failure was related to combustion chamber cleaning. The manufacturer was contacted, who informed the diagnostic fees were at her expense and there was no coverage. The failure mileage was approximately 94,700.

The vehicle is burning oil even when oil changes are done routinely. Then all of a sudden I have total loss of power will not go over 35 miles an hour. And climbing hill would not go over 20. It just happened no warning lights on dash so now I have a car that is still owning 8 grand on. So now a lawn ornament. I have seen on different formats. That there is hundreds having the same issue. Hyundai is not fixing the issue for any of us.
