2019 Hyundai Santa fe

My 2019 Hyundai Santa Fe 2.4L (VIN: [XXX]) is experiencing a severe safety defect involving rapid engine oil starvation. The vehicle recently failed an official oil consumption test conducted by Fred Beans Hyundai of Abington, where it was documented that the engine consumed 1 quart of oil in just 881 miles (PA Request #XXX). This vehicle is equipped with the Theta II engine, which currently has active warranty extensions (TXXC and TXXI) specifically covering connecting rod bearing failure. Despite the documented severe oil loss—which is the primary known cause of connecting rod bearing wear and sudden engine seizure—Hyundai Corporate (Case #XXX) is refusing to evaluate the vehicle under these warranties. They have improperly classified my claim as a denied "goodwill" request and are refusing to perform a connecting rod bearing clearance test to determine if the bearings have been damaged by this starvation. Because Hyundai refuses to perform the required diagnostic safety protocols, the vehicle must be driven in an oil-starved condition. This poses an imminent and severe safety risk of sudden engine seizure, stalling, and complete loss of motive power at highway speeds without warning, which could result in a catastrophic crash. The manufacturer is ignoring their own failure thresholds and putting driver safety at risk. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On March 04, 2026, I took my 2019 Hyundai Santa Fe to the local dealer for oil change service. As part of that service visit, they performed Hyundai recall 9C1 which was supposed to lower tailpipe emissions. The next morning, and ever since, my vehicle ran differently. The engine had several 1000rpm surges and was sluggish at other times. This behavior has continued. Particularly when I first start out in the morning and the engine is cold. Never after the engine is warmed up. A visit to the Hyundai forum shows a growing list of other Hyundai owners who are experiencing the same issues. This recall is defective and should be corrected.

In December 2025, a Hyundai dealer performed Service Campaign 9C2 (TSB 25-01-087H), an ECU software update for the 2.4L GDI Theta II engine, during a routine annual NY state emissions inspection. Immediately following this update, the vehicle began exhibiting an RPM flare of approximately 1,200-1,500 RPM during upshifting under light acceleration. This behavior did not exist prior to the update. The condition occurs when ambient temperature is above 50°F and the vehicle has been parked 2+ hours after a prior drive. No warning lamps or fault codes have been present at any point. The issue has been confirmed across four dealer visits at two Hyundai dealerships over five months. Attempted remedies included transmission ECU updates and adaptive resets — none resolved the condition. On the fourth visit, the technician personally experienced the issue and identified reinstalling the pre-update ECU calibration as the likely fix, but stated the prior software version was unavailable. The repair order was nonetheless closed as "vehicle operating as designed." The case has been escalated to Hyundai Motor America National Consumer Affairs and forwarded to Hyundai engineering with no resolution to date. Multiple other 2019-2020 Santa Fe owners report identical post-9C2 symptoms on public forums, indicating a pattern associated with this campaign's ECU calibration. The unexpected RPM surge and erratic shifting during acceleration creates an unpredictable driving experience that could cause hesitation in traffic situations requiring smooth acceleration.

Vehicle: 2019 Hyundai Santa Fe, VIN [XXX] , exterior Quartz White Pearl. Component: Exterior factory paint (paint/trim). Complaint: This vehicle exhibits a systemic, progressive factory paint defect — excessive peeling and bubbling of the white finish that spreads from one body panel to the next. This is a known defect across this vehicle generation; Hyundai acknowledged it by issuing Warranty Extension Z05 (TSB 25-BD-004H), which extends paint coverage to 10 years/unlimited miles for affected white-paint vehicles including the 2019 Santa Fe. Hyundai repaired the hood under this warranty in 2025, during which the vehicle was out of service for 77 consecutive days. Since that repair, the defect has migrated to the adjacent fender and has also appeared on a door, demonstrating that it is spreading across the vehicle. Hyundai has offered to repaint only the single currently-visible panel rather than addressing the systemic defect. I am filing this complaint to document the defect and its progression, and to support the public record regarding factory paint failure on these vehicles. No crash, injury, or fire has resulted. The vehicle is owned by my spouse; I am submitting as authorized representative. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Hyundai recently had a service campaign that was issued to address an emissions related issue in CA. The service campaign was 9C2 and the TSB was 25-01-087H. After this software update was applied to my vehicle the engine is now sluggish on a cold start and the transmission is shifting differently at low speeds and low gears. It appears that the performance of my vehicle has been compromised. There is a Hyundai forum where many Santa Fe owners are experiencing the same issues after the software update. I have notified the service advisor at my local Hyundai dealership.

Engine is burning a tremendous amount of motor oil. Dealer does acknowledge engine is burning oil. No warning lights on. Told burning motor oil is normal for a hyundai engine. Engine can seize during driving with no warning and is a safety issue. Front struts are also failing. No warning and is a safety issue: Currently trying to get dealer to cover defective components under warranty. Nothing has been repaired or resolved as of yet.

Vehicle Information: 2019 Hyundai Santa Fe Mileage at failure: approximately 109,000 miles Manufacturer: Hyundai Motor Company The vehicle experienced a complete failure of the automatic transmission system. The failed component is available for inspection upon request. At approximately 98,000 miles, the vehicle’s check engine light illuminated. I brought the vehicle to an authorized Hyundai dealership for diagnosis while it was still within the 100,000-mile powertrain warranty period. The dealership inspected the vehicle and advised that no issue was found, and no repairs were performed at that time. Approximately 11,000 miles later, the vehicle experienced severe transmission problems, which progressed to complete transmission failure at approximately 109,000 miles. Safety Risk: The transmission failure resulted in a sudden loss of power and reduced vehicle operability while driving. This condition presents a potential safety risk to the driver and surrounding traffic, particularly during normal roadway and highway use. Prior Inspection / Diagnosis: The issue was not identified or reproduced during the dealership inspection at approximately 98,000 miles when the check engine light was present. Other Inspections: The vehicle was inspected by a Hyundai dealership at approximately 98,000 miles. No inspection by police, insurance representatives, or manufacturer engineering personnel has occurred since the transmission failure. Warning Signs: Check engine light illuminated at approximately 98,000 miles Vehicle was taken to dealership for diagnosis at that time No specific transmission warning messages were displayed Dealership reported no issue found Maintenance History: The vehicle has been regularly maintained with oil changes performed approximately every 5,000 miles. Maintenance records are available for review upon request.

Engine continuously burns oil excessively and the dealership is falsifying the oil consumption test. At my local oil change shop, there is no oil left on dipstick at 3,000 mile interval. When I took it to dealer for consumption test, they checked dipstick after 1,000 miles and it was OVER THE FULL LEVEL. How can the oil be over the full level? This indicates they overfilled it to begin with and invalidated the test. Hyundai corporate is doing everything they can do avoid addressing this issue with the 2.4 engine in these models. Additionally, the transmission already failed less than 70k miles on the car.

we took it in to be looked at after it had a o2 sensor go bad I changed the sensor and checked fluids I noticed the oil was a touch low and it had metal on the dipstick. I took in to dealership for repair / replacement and Hyundai denied the claim. Even after I have video proof from the dealer technician saying there is metal and bearing material in the oil. I took it to another dealership and they found metal in the oil control valve and still denied it. We got the car back because we were not provided a loaner or a rental. I called back in with concern that the car had a weird burning smell and the car would die. Then it started sounding weird as well. Then called again Saturday because I checked oil and it had fuel smell in the oil. Now today it left my family stranded on the highway. I have th 100,000 mile ten year warranty and the car is only at 83480 miles now when this all started it was at 82000. I have expressed my concern of safety before it finally left my family vernable to be injured in the lane that it died in This afternoon. Many denied claims and now very dangerous situation that was preventable and could have cause fire or death. I brought to manufactures attention early to prevent a accident happening. I was denied all the way through the process .

The door was completely shut - I was driving on the highway - no alarm on the instrument panel, fully stage 2 latched ( even if it is just stage 1 latched - the instrument panel gives an alarm - there was no alarms about door not fully closed) everything was normal. 15 minutes into the drive - I was exiting the highway, making a right hand turn - the door suddenly popped open, alarm went off on the instrument panel - thankfully did not swing open, I was able to hold onto the door. I shut the door again - drove for 200 Miles - no issue again. This was the first ever time I saw this issue at 90K miles

The trunk hatch is no longer functioning. The car beeps, but does not unlatch. Once the gate is manually open from a latch inside the trunk, it will not close by pushing the gate close button. It just stopped working. I went into the grocery store, and when I returned with groceries, it stopped working. Hyundai says it's out of warranty and will cost $1800 to repair.

Paint is significantly peeling on the hood of my car.

The contact owns a 2019 Hyundai Santa Fe. The contact stated that while driving approximately 45 MPH, the vehicle hesitated while accelerating with the accelerator pedal depressed and the RPM raised. The contact stated that the vehicle occasionally failed to start. No warning light was illuminated. Additionally, while driving at various speeds, the vehicle lost automotive power. The vehicle was taken to a local dealer, where it was diagnosed, and determined that there were metal shavings in the oil pan. Hyundai Eugene (89320 N Game Farm Rd, Eugene, OR 97408) was contacted; however, the failure was not identified. Upon further investigation, the Hyundai Blue Link App retrieved DTC associated with the Power Train EMS and Power Train TCU. The vehicle was not repaired due to the cost. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 87,000.

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.
