2019 Hyundai Santa Fe

Since December my car has been burning oil at a fast rate. My husband has already had to add an additional 4 quarts since my last service 3000 miles ago. I have read and heard from others with a Santa Fe that they are having to replace their engines because of this. They are under warranty. Unfortunately I am not. I’ve already dealt with a white paint issue with Hyundai. I called couple weeks ago and was told someone would email me and they have not. I’m not sure where to turn now.

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.

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.

Complaint: Safety Defect - Engine Failure Risk (Stalling/Fire) My 2019 Hyundai Santa Fe has the defective Theta II 2.0L Turbo engine (G4KH), subject of class action In re: Hyundai and Kia Engine Litigation and multiple TSBs. The engine has a known manufacturing defect causing premature connecting rod bearing failure, leading to catastrophic engine seizure. SAFETY CONSEQUENCE: This defect presents a clear, unreasonable safety risk: Sudden Stalling: Engine can seize without warning while driving, causing loss of propulsion and power steering/brakes, leading to a crash. Engine Fire: Failed engines can leak oil onto hot components, causing fires. MANUFACTURER'S INADEQUATE REMEDY: Hyundai's "Knock Sensor Detection System" software update (Campaign 966) only attempts to detect failure moments before it happens. It does NOT fix the underlying mechanical defect. The engine remains a ticking time bomb. PERSONAL EXPERIENCE: My vehicle has suffered multiple related failures (turbocharger, fuel injectors) costing over $5,700, confirming the powertrain's deterioration. I fear driving it, especially with my teenage daughter. The defect is well-known, yet Hyundai's settlements fail to protect subsequent owners like myself, leaving unsafe vehicles on the road. REQUEST: I urge NHTSA to investigate the ongoing safety risk these engines pose to all owners, compel Hyundai to issue a true safety recall for a permanent repair (e.g., engine long-block replacement), and mandate clear disclosure of this defect to all used car buyers.

internal mechanical failure of the piston rings and cylinder walls. Misfire on Cylinder #2. Further testing revealed that Cylinder #2 is at 80 PSI, which is significantly below the manufacturer's specification. A subsequent leak-down test showed a 90% loss of pressure with air escaping through the oil filler hole. The issue stated above can cause severe mechanical failure of piston rings and cylinder walls can absolutely lead to connecting rod bearing problems by creating excessive debris, poor lubrication, abnormal piston motion, and increased stress, causing premature wear, overheating, and eventual bearing failure, often resulting in catastrophic engine knocking and damage.  Diagnostics completed by Hyundai dealer and stated an engine replacement. Vehicle became difficult to steer and then warning lamp came on. Vehicle was difficult to turn left and right and almost caused a collision.

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.

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.

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.

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.

Overly excessive oil consumption 2 Quarts every 3 or 4 days.no leaks. Engine gets so hot I don't have to turn on heater In winter. On going issue since 100,000 miles. EBS light stays on electronic parking brake switch does not work. Parking brake will randomly engage after vehicle is turned off. Dealership cannot duplicate issue. If cruse control is turned on the vehicles warning lights all of them will suddenly illuminate and the vehicle shuts off. alternator and battery replaced. Have not used cruse control since. Airbags never inflated in a front end crash at 45mph Most recently I started experiencing I intermittent trouble staring the car. Then one day it didn't start at all and smoke was coming from under the hood. Towed to mechanic , starter burnt up 155,000. $ 900 to replace then a couple days later I lost power on the freeway and the car started jerking and vibrating. Stopped Vehicle cut off and would not start. After 1hr I started and limped home. Vibration under 2000 RPMs and when stopped. Knocking noise under hood. Brand new spark plugs. Mechanic stated Cylinder 3;missfire was identified as a hole in a valve due to weak material now I have to replace engine. Oil consumption and excessive friction and heat is to blame. My car has been cared for like a baby it's all I have. I should not have to be responsible for this very cheaply made engine that was doomed to fail.

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.
