2019 Hyundai Santa Fe Engine Problems

My Hyundai Santa Fe 2019 Limited is burning oil. It started after the Turbo broke in October 2024. The turbo began leaking oil and then died. I took it to the dealership as it is still under warranty and they replaced the turbo. As a result, I have had issues ever since and now my car burns oil at a fast rate. In between oil changes I need to put oil in the engine to avoid it being drained. I am able to go about 3k miles on Synthetic oil and by 2.5-3k it is almost empty. It has been doing this now since 2024. I just had my 90k mile check up complete and with that I got an oil change. This was done in November 2024. Syntehtic oil was used. On January 16, as I was driving my car mileage decreased, the car began to shake and the engine light came on. I was able to safely stop and have the car towed. It was found that after driving just 2k miles the oil had completely burned off. I currently have an appointment at the dealer for them to run diagnostics on why it is burning. I saw there was a class action lawsuit against other Hyundai's doing the same thing and as a result Hyundai has to replace the engine. I also have read numerous forums where everyone is reporting the same thing with this particular model of it burning oil. I wanted to report this in case there were other owners of the same car experiencing the same thing.

On my 2019 Sante Fe 2.0T, I started having oil consumption/engine issues after 85, 000 miles. Under warranty, I had several minor repairs made over the last year (since 87,000 miles) at the dealership. In September 2025, at 97, 500 miles, I had it into the dealership complaining of burning oil and excessive consumptions in between oil changes. They AGAIN made a few minor repairs, I signed a one-owner warranty form since it was prior to 100,000, and they said come back if I experience further issues. On December 21, at 9pm at night, I broke down on the side of the PA turnpike. My engine light came on after my car started shaking vigorously, and wouldn't accelerate beyond 30mph. Being a Sunday night, I called the dealership in the morning- I was told no appointments for 3 weeks. Took it to a mechanic- where they diagnosed engine failure- hole in intake vale and floating valve not seated. Towed to dealership where it was INITIALLY diagnosed spark plugs and engine coil. Once a mentioned I had a prior diagnosis and pictures, Hyundai did bioscope- found burnt valve and now need all new intake values and part of the engine rebuilt. Hyundai wants me to pay for repairs. I don't think I should have to pay a dime- I've been complaining for over 15,000 miles BEFORE my warranty expired. And now, at 102, 000 miles, the engines blown?? This is a known manufacturer defect with the Theta II engines, and the pistons. I would expect Hyundai at the VERY LEAST to cover the cost of the repairs. Quite frankly, they should replace my engine with a new one, since replacing valves wont solve the pistons and burning excessive oil anyways. I have all documentation of repairs at the dealerships, email correspondence sent between the dealership's service advisors and myself, as well as my routine oil changes.

After several oil changes and going from ever 5000 miles to every 3000 miles for oil changes to the need to add additional oil before hitting 3000 for being low on oil. Was told this vehicle just burned oil often and nothing really i was able to do. Check engine light turned on. Car stalled, shook and even turned off after being idle too long. Diagnostic found a leak in a cylinder and no combustion in engine. Out of warranty coverage. No warning lamps came on prior. Was on the freeway when light came on luckily was able to pull over safely. Seen many other cars with similar year, make model and engine had similar issues with oil consumption leading to the need of a full engine replacement. Further reading into issue showed several class actions and recalls to similar situation.

Driving on interstate when the car all of a sudden started shaking and the check engine light came on. Had it towed to repair place who said they could not touch it and had to go to Hyundai. Towed it there. Just advised today of the issue and that Hyundai wouldn't cover it. Car has just over 100k miles on it. The engine should not fail this soon. Cylinder 2 no compression was the reported issue. Without a car for several weeks.

Vehicle is consuming oil at an exceptionally fast rate. In October 2025, when taken in for an oil change and my complaint of a burning smell upon quick acceleration, the technician documented no oil was found on the dipstick. Just a month later, in November 2025, the oil level was already extremely low, the vehicle was taken back to the dealer, and an oil consumption test is currently being administered. The vehicle is scheduled for an engine replacement in January 2026 after the consumption test is concluded.

Engine oil consumption issue. I have taken the vehicle in 4 times due to this they have. Changed hoses and even the oil pan but the engine still runs out of oil. On several occasions the oil light comes on within 1000 miles of a oil change and when I check it the system is completely out of oil. This means the lubrication system is running with no oil and likely has metal particles in it. I have contacted Hyundai corporate and the issues still has not been resolved. There needs to be a recall on these engines before they start blowing up. I uploaded files of thw most recent service nov 5th and the current odometer reading and oil level. 7 days later the oil level is low.

This vehicle requires 1-2 quarts of oil to be added to it weekly. It's all over the internet that many different models of Hyundais consume excessive amounts of oil. This puts others at risk due to damaging the engine and the possibility that the car will just stop completely while driving it. We have records to show how often and how much we have to add more oil every week.

The car is burning oil and Hyundai advises to change the oil every 7500 miles. The car holds 5.1 qt of oil and is currently burning about 1 qt of oil for every 5,000 miles. How is this not a forced recall? People are blowing up their motors all over the country. They knew it was an issue and bought their way out of a class action lawsuit. This endangers any driver if it happens on the interstate. Hyundai/Kia are being allowed to skirt accountability with these motors.

Yesterday afternoon after running errands, my car was off and in my driveway. Within 15 minutes I noticed it was smoking. When I opened the hood. The engine was on fire. I attempted to put it out but was unsuccessful. 911 was called and responded to put the flame out. The car was destroyed. I recently had my engine resealed and turbo replaced at a Hyundai dealership. I picked up my car following repairs on April 18th.

One cylinder of the engine is misfiring. When I bought it used in 2021, I realized it had a problem. At red lights or stop signs, the car would randomly not accelerate when it was time for me to go. I would have to turn it off, then on; shift to park then drive; or mash hard on the gas for the car to recover. For example, it happened at these days and times in 2024 (I didn't write down every time since ownership began): 1/24/24 and the key icon lit up; 3/14/24 at 9:20 am; 4/20/24; 7/19/24; 8/7/24; 8/18/24; 8/21/24 at 10:40 am; 8/25/24; 8/27/24; 9/7/24 at 12:30 pm and 3:21 pm; 9/12/24 at 10:38 am; 9/20/24; 9/21/24 at 1:43 pm; 9/23/24 at 7:38 am; 11/12 at 9:36 am; 10/26/24; and 10/27 at 4:37 pm. It was scary! I took the car to the Hyundai dealership in September 2022 and in October 2022 for this issue and the alert that Forward Collision Assist warning wasn't working. I was told both time that they didn't know why the first happened and recommended I replace the entire bumper for the second (it's no longer happening and I did not replace the bumper). I reported it to Hyundai Customer Care and nothing happened. The car also required 4-5 quarts of oil every 2000 miles. I believe these were precursors to what happened this month. On April 5, 2025 the car completely stopped while I was driving on the highway. I added oil and it chugged to an oil change shop where the diagnosis was a problem with coil 3 in the engine. I went to an auto parts store and replaced coil 3, and the car chugged just enough for me to get home. I had a tune up and the mechanic put Heet in the gas tank in case it was a fuel injection issue. The car didn't improve so I took it to another mechanic who diagnosed a misfire in the third cylinder as well, and the spark plug in the third spot looked brand new though the other three showed a bit of wear from the few days I used the car. He told me the engine problem was serious and needed a dealer's examination. I will go to the dealership on 4/17/25.

Oil consumption on vehicle engine leading the engine to run low on oil for extended periods of time

The vehicle was burning through oil excessively. I was adding 1 quart of oil a week. Dealer did an oil consumption test. They confirmed the engine needed replacement. These vehicles are getting to be known for this issue and the dealer is making me pay 40% of the repairs. They should be covering 100% because the issue is not isolated to my vehicle only.

Oil Pan leaks after an oil change. Oil pan has a hairline crack just below the drain plug after normal tightening of the plug. Excessive oil was found on my driveway. No obvious engine damage, considering the vehicle was only moved from one spot to the other. The dealer stated the oil pan isn't covered under warranty. I simple internet search revealed there was a high number of complaints. It was a "Do It Yourself repair." The cost to fix was to replace the oil pain, new tools and 5 quarts of oil.

There is a system in the car that starts and stops engine, supposedly only at lights to save on fuel. Mine has stopped in the middle of a highway on my way up to Tahoe. Luckily I had just left light and only driven enough to reach the speed of about 10 miles per hour so the cars behind me were able to stop and not hit me. I had to completely turn the car off, put in park and restart car to get it to operate. It has stalled out like a stick shift would if not handled properly, but it is an automatic transmission, on numerous times. Sometimes this will cause the vehicle to completely shut down and sometime it will sputter for a few minutes and then slowly pick speed up and stop. The IGS button to turn this feature on and off when you get into the vehicle will sometimes stay off (not supposed to) and sometimes turn back off as it is supposed to each time the vehicle is turned on or off. It doesn't register as a recall, but I have done my research and saw that at one point you guys had done an investigation into this exact problem with my car. It doesn't show up on diagnostic and it doesnt do this every time I drive. So I have no way to show mechanics the isues. But this puts my life and anyone in my cars lives at risk. Not to mention any cars behind me if this happens on the highway again. I dont know what to do :( Can you please help me?

This has been an ongoing issue since the date of purchase 10/23. I've been taking my vehicle for regular check ups and oil changes. My vehicle appears to be consuming oil. I have to put a quart in every week, but no one can find the issue. The dealership told me there is a recall on these particular vehicles engine.
