2017 Hyundai Santa Fe Engine

Purchased this 2017 Hyundai Santa Fe from dealer with 86K miles. (second owner). Immediately noticed excessive oil consumption. Would take vehicle in for oil top off service, to ensure proper levels. At 99K miles (six months after purchase) lost compression in #2 cylinder while driving on the freeway. Per independent auto repair facility and a Hyundai service center, engine replacement is needed. Hyundai declined engine replacement. It appears oil consumption was an issue when the vehicle was traded in to the dealership, and they resold it anyway to an unsuspecting consumer.

Current Mileage: ~94,000 miles Ownership: Second owner (purchased less than one year old at 17,035 miles) I purchased this vehicle in December 2018 when it had approximately 17,035 miles. Since purchase, the vehicle has been consistently and properly maintained, primarily at authorized Hyundai dealerships, with documented oil and filter changes throughout my ownership. All required Hyundai recalls and updates have been completed. As confirmed by Hyundai service records, my vehicle is eligible for extended warranty protections under the Theta II Engine Settlement, which explicitly applies to subsequent owners and is not limited to the original purchaser. Engine Failure & Repair History Beginning in mid-2025, my vehicle began to exhibit progressive and excessive oil consumption, despite regular maintenance. Hyundai dealerships performed multiple Hyundai-directed corrective actions, including: PCV valve replacement Multiple oil consumption tests Combustion chamber cleaning (paid out of pocket after Hyundai Motors denied goodwill) These measures failed to resolve the issue. Hyundai’s own oil consumption testing confirmed: 1.2 quarts consumed, followed by 1.4 quarts consumed, indicating worsening internal engine failure West Houston Hyundai has subsequently advised that engine replacement is required, yet Hyundai Motor America has refused coverage, and I was quoted $5,872 for engine replacement and labor at my expense. Engine failure requiring replacement at 94,000 miles is not normal wear and tear and is inconsistent with reasonable consumer expectations or Hyundai’s powertrain representations. Importantly: The vehicle has never been cited for neglect, sludge, or improper maintenance,Oil consumption worsened after Hyundai-directed repairs Hyundai has not identified any misuse or disqualifying condition The failure pattern is consistent with known Theta II piston/ring defects

documented oil-consumption issue with my 2017 Hyundai Santa Fe, which currently has 98,876 miles. This concern was first formally reported in October 2025. Since that time, I have fully complied with all diagnostic and procedural requirements requested by the dealership, including inspections, documentation, and follow-up visits. The dealership has acknowledged that the vehicle has an ongoing oil-consumption condition. Per the instructions provided by Hyundai Service Team, I was advised to “submit my own claim.” I later learned that, as a customer, I am not permitted to submit or appeal a claim directly, and that only the dealership has the ability to do so. I have since been informed by Customer Care that the claim submitted on my behalf was considered weak, which may have contributed to its denial. I was also advised that Hyundai and the dealership were already aware that I did not have the ability to submit or appeal the claim myself, despite being directed to do so. Throughout this process, I have made every good-faith effort to follow Hyundai’s guidance, yet I have experienced repeated misdirection and inconsistent information. This has caused unnecessary delays and frustration while the underlying issue remains unresolved. The vehicle has been properly maintained, with regular oil changes and servicing completed according to Hyundai’s recommended intervals. Despite this, the excessive oil consumption persists and poses a risk to engine longevity and overall safety. Due to the current condition of the engine, I no longer feel it is safe to continue driving the vehicle, which has left me without reliable transportation. Additionally, I have previously experienced the theft of this vehicle, for which I was not compensated, despite the well-documented safety concerns affecting Hyundai customers. Taken together, these issues have significantly impacted my confidence and ability to rely on this vehicle. Given Hyundai’s well-documented history of oil-consumptio

Engine failed at approximately 95000 miles.

My Hyundai Santa Fe has a major oil leak from the oil pressure light. I took the car to a non-Hyundai shop for repair and was told that the problem should be covered under recall campaign 168. Reference Number: 17-01-071, Date of issue: December 01, 2017. A quick check of internet complaints indicates this is a common problem with this type vehicle. My oil pressure light is on at idle after the car is warmed up. Reno Hyundai dealer informs me that it is not covered by recall. I believe that this problem should be covered based on the volume of complaints from other owners. Can your organization help me in getting some kind of an cost adjustment for getting this repaired. Thank you.

My 2017 Hyundai Santa Fe began consuming oil at an excessive rate—approximately one quart every 250 miles. The vehicle had around 97,000 miles when I first became concerned. I brought it to the Hyundai dealership for evaluation, and they instructed me to continue driving the vehicle and return after 1,000 miles of driving so they could document the consumption. I returned after only 500 miles because of the rapid loss of oil and my concern for driving the vehicle in that condition. While following the dealership’s required oil‑consumption test procedure, the engine performance deteriorated. The vehicle eventually began stalling and had to be towed to the dealership. Because I was required to keep driving the vehicle as part of Hyundai’s diagnostic process, I accumulated an additional 4,000 miles, which pushed the odometer just over 100,000 miles. After completing the test, the dealership submitted a claim for an engine replacement, but Hyundai Corporate denied the claim solely because the mileage exceeded 100,000—despite the fact that the over‑100,000 mileage resulted directly from Hyundai’s own required testing procedure.

Vehicle: 2017 Hyundai Santa Fe On June 9, 2024, when my wife started the vehicle, the engine was immediately knocking. Due to concern for safety and the risk of catastrophic engine failure, the vehicle was not driven and was towed to our home to prevent further damage. Hyundai was contacted shortly after discovery of the issue. During a phone call, we were told there were no active recalls applicable to our vehicle and no replacement engines available. Due to the lack of immediate support and the vehicle being undrivable, we were forced to send the vehicle to a third-party mechanic on June 14, 2024, to complete a necessary engine repair. On August 21, 2024, we received warranty documentation from Hyundai related to this issue. Despite providing all requested documentation and Hyundai contacting the third-party mechanic directly, the warranty claim process was repeatedly delayed. We were told multiple times that the case was in its final stage, only to later be assigned a new case manager with no knowledge of the case, requiring the process to restart. The vehicle was not returned to us until April 7, 2025, resulting in an extended loss of our primary vehicle for our family. We paid approximately $10,000 out of pocket for the engine repair while the warranty claim remained unresolved. We have since been informed that Hyundai may require the engine to be repaired or replaced again by a dealer with no reimbursement, potentially rendering the previous repair and financial loss unnecessary. This raises serious concerns regarding Hyundai’s handling of a known engine issue and their warranty process.

I purchased my 2017 Hyundai Santa Fe Sport secondhand from CarMax and have maintained it regularly with timely oil changes and tune‑ups. Despite this, the vehicle is burning oil at an extreme rate—approximately 1 quart every 378 miles. My local Hyundai dealership confirmed this through three consecutive 1,000‑mile oil consumption tests, all showing excessive oil loss far beyond normal operating limits. This level of consumption appears to indicate an internal engine defect, not normal wear. Hyundai corporate denied my case solely because I am the second owner, even though the vehicle is well under 100,000 miles and the defect has been verified by their own technicians. The denial did not address the confirmed test results or the safety implications. I am deeply concerned that the engine could seize while driving due to rapid oil loss, creating a serious risk of sudden loss of power, stalling, or inability to accelerate in traffic. This is a significant safety hazard for me, my passengers, and other drivers. The vehicle has been inspected by the Hyundai dealership, and I am fully willing to make it available for further inspection. A low‑oil warning lamp appeared far earlier than expected after a routine oil change, which prompted the initial investigation and ultimately revealed the defect. Based on my research, this appears to be a known issue affecting Hyundai GDI engines from this era. I am filing this report because the excessive oil consumption represents a latent engine defect with clear safety implications, and Hyundai has declined to address it despite documented evidence.

Check engine light came on Oil Light came on then the vehicle shut off while I was driving. Safety was not good as I was driving the vehicle. I then had it towed to a shop to have it looked at. That is when I was told I would need a new motor due to a Crankshaft failure. The check engine light had come on the night before but when turning the vehicle on the next morning to take it to get looked at it was no longer on. Was driving it too the shop to have it looked at when it shut off on me while driving.

It sounds like the rod inside are hitting need a new engine. Auto shop said need a new engine. Engine has 125000 that all no oil leak no other problems.

My 2017 Hyundai Santa Fe experienced a sudden and complete engine failure without any warning signs. There were no warning lights, no check engine light, and no unusual noise before the failure. The engine stalled while trying to start, ran very rough for a second, and then completely shut off. After that, the engine would not start again at all. A certified independent mechanic inspected the vehicle and confirmed the engine suffered a mechanical failure consistent with rod bearing wear or crankshaft damage, which is the same issue described in Hyundai’s known engine safety recalls. I later took the vehicle to a Hyundai dealership. They also confirmed that the engine had failed, but said it could not be repaired under Hyundai’s programs because my vehicle was not listed in the specific recall. 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 shutdown created a serious safety risk, especially because there was no warning before it failed. This failure matches the symptoms described in Hyundai’s Theta II engine defect investigations. 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.

The engine seized back in August 2025. The engine stopped working while I was driving on a Main Street and almost caused an accident. Unfortunately I put other drivers at risk when this happened. The engine issue was confirmed and inspected by the victorville Hyundai dealership in California. There was not any warning lamps prior to this.

My vehicle has never missed an oil change or maintenance event yet at my last oil change my engine had burned through all its oil and no low oil light or check engine light came on. Hyundai is refusing to cover it under their warranty stating it occurred due to maintenance neglect even though all oil changes and maintenance events receipts were provided to Hyundai and are available in car fax.

What component or system failed or malfunctioned, and is it available for inspection upon request? Blown head gasket How was your safety or the safety of others put at risk? Engine overheated and coolant boiled in 110 degree weather. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes by Hyundai. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes by Hyundai. Hyundai states that engine needs to be replaced because the head gasket isn’t repairable on the 3.3L engine. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, engine overheated once and diagnosis was blown head gasket.

In October I took my car to dealership for an oil consumption test and I was going through 10-15 quarts of oils between oil changes. In 322 miles I used 2 quarts of oil.Replace the engine is what I was told and manufacturer denied all goodwill. I ride around with a 5qt jug of oil and funnel in my car at all times. 10 days I was driving down the highway with my husband and child with the cruise control on, when I noticed that my tactometer was continuing to increase and the engine reving for no reason. I shut the cruise control off and the car speed slowed immediately, and when apply my foot to the gas I was not gaining any speed only slowing down. I pulled over into the break down lane and put the car in park. Once I put the car into park, it started to idle very loud and hard with the check engine, oil pressure and battery lights coming on and stalled, would not start. Had towed to personal mechanic he recommended taking it to the dealership as he was coming up with no pressure in the 4th cylinder and the 3rd at about 50%, checked with boarscope for faulty valves and saw nothing. Towed to dealership they say valve was consumed thru the engine it runs fine but not because engine needs to be replaced.

I took my Hyundai Santa Fe sport to Central Valley Hyundai in Modesto, CA on 10/31/2024 to have a diagnosis done to the car since the car turned off on me while I was driving and after a week being at the dealership this was their response. Hello [XXX], sorry for the late reply! We are short handed today, and busy! Anyways, My technician had the chance to take a look at your vehicle. Your vehicle is going to need an engine due to it not passing the bearing clearance test. I submitted paperwork to Hyundai and I am currently waiting to hear back from them in regards to a decision. I will let you know as soon as I hear something. after another week went by this is what Hyundai had to say. I just checked, and they declined the coverage of your engine, this was their response: The vehicle is not eligible for extended warranty TXXI. Per the terms of the extended warranty, the campaign 953 software must have been installed on the vehicle prior to bearing malfunction. Our records indicate campaign 953 was not completed on this vehicle. For further clarification, the terms of the extended warranty and related settlement. Notice may be reviewed here. [XXX] . No goodwill assistance is being offered at this time I was never made aware of a recall that needed to be done to the engine. I never received a letter in the mail and also I spoke to Hyundai customer service and they said that I never received the notice due to being sent to the original owner which was a car rental business.

Engine excessively burns oil. Failed oil consumption test. Hyundai denied warranty claim, citing maintenance neglect, despite oil change maintenance records and documentation.

Engine failed at 114,000 miles. Burned 2 holes through 3rd cylinder. was almost struck crossing intersection making left hand turn when vehicle stalled and would not accelerate to get back into normal driving lane.

Engine went into limp mode and a knocking sound was heard. Had car inspected and oil changed but no improvements occurred. Took car to dealership and it failed engine test. Hyundai will not cover replacement under open extended warranty.

While driving my 2017 Hyundai Santa Fe Sport, I heard a knocking sound coming from the engine. Shortly afterward, the vehicle began moving jerkingly forward, and the oil, engine, and battery warning lights illuminated on the dashboard. The vehicle then shut off completely in the middle of a busy street. I attempted to restart it, but while the engine made a starting sound, it immediately shut back down. The electrical system remained functional (lights and radio), but the vehicle would not restart. Due to the failure, I had to exit the vehicle and physically push it to the side of the road in cold, rainy conditions with reduced visibility, creating a risk of being struck by oncoming traffic. Strangers who assisted in moving the vehicle also placed themselves at risk. A certified mechanic has since confirmed that the engine has locked up and identified this as a known issue with Hyundai engines. Prior to this incident, the only warning sign was the oil light briefly flashing while driving on an uneven road surface. At the time, I was on my way to have an oil change within the manufacturer-recommended time frame and assumed the light indicated routine maintenance was needed.

At about 105,000 miles the oil ran dry after 800 miles of fresh oil change, it just started using oil no leaks no smoke from the tailpipe.now I have to add a qt every 200 miles and on start up the top of the engine rattles for a few seconds. A loud rattle. I have taken it to the dealership several times they did a engine cleaning and several other things but it didn’t help just cost about 800 bucks. Prior to that we changed oil every 5000 miles. Not always the same place, the dealership, Tess corners auto did quite a few of them. Some by jiffy lube. We don’t take the car on long trips anymore, afraid it will not make it. Karen n Chris

Approximately six weeks after purchase, my daughter drove the vehicle to a school event and back without issue—no warning lights, noises, or drivability concerns. Shortly thereafter, when attempting to leave for another event, the Santa Fe failed to start. I attempted a jump-start, only to discover that the engine had seized suddenly and without prior warning. It is available for inspection if needed. This sudden and unexpected malfunction could have happened while driving down the road and who knows what might have happened to include my daughter being seriously injured. The vehicle was towed to our local Hyundai dealer. where the service team confirmed catastrophic engine failure. The Engine has only been inspected by the local dealer. There were no warning lights, noises, or drivability issues prior to the engine failure. This engine failure happened on Aug. 16, 2025 References for Review NHTSA Recall Report 17V-578 – notes crankshaft pin and bearing wear issues leading to potential stall.

My vehicle we bought from carvana has been jerking/misfiring and now with no warning on freeway it wouldn't give power stalling. There was no warning nothing no lights came up. I drive my kids in this vehicle I've taken it to multiple mechanics they say they couldn't find why it's jerking and it must be a manufacturer issue. I looked online and yes lots of issues with the make and model recall about the crankshaft sensor cause these issues!!!
