2018 Hyundai Santa Fe Sport

I own a 2018 Hyundai Santa Fe Sport. I leased it new, then purchased outright in May 2022. I had no issues with my vehicle. I maintained it regularly. Had appropriate interval oil changes. At no time from 4/2018 to 6/2025 did I have any knowledge of any issues with the engine in my vehicle & neither Hyundai nor the dealership contacted me in any manner to notify me of an issue with my engine. On or about October 2024, my check oil light came on for the first time in 6 years. I do not drive much because I work, & have worked, from home since July 2020. I took my car to my mechanic. He added almost 4 quarts of oil. I returned two weeks later & he changed oil. He saw nothing that caused him suspicion. He suggested I check my oil levels. Extreme oil consumption continued. My check oil light NEVER came back on. No other lights came on until 10/6/2025. I drove minimally. In July, 2025, I discovered my vehicle has a known defective engine. I uncovered multiple lawsuits against Hyundai regarding the defective engines. On 9/12/2025, I sent a Massachusetts General Law 93A Demand Letter mailed Certified Mail to Hyundai & dealership. On Oct. 6, 2025 at approx. 11:30 am, I turned on my car & without warning, my car immediately began shaking violently & vibrating & stalling - IN PARK. The check engine light began to flash intermittently in PARK. I drove my vehicle 7 miles to my mechanic (praying the whole time my car would not blow up with me in it); the car violently shook & vibrated the entire 7 miles. The check engine light changed to solid & acceleration was almost non existent. I am waiting for my mechanic to most likely give me bad news. Neither Hyundai nor the dealership have yet responded to my MGL 93A Demand Letter.

I have taken my car to the dealership now 3 times for the same recall issue. This time, they are telling me Hyundai will not repair my car on their end because of "sludge buildup" to which i was not aware. I submitted all records of maintenance and they are refusing to fix my vehicle. I now have an inoperable, because not safe, vehicle that is legally required to be fixed by Hyundai for it's recall, but is not being fixed. Recall 237 If I were to try to drive the vehicle, it could put lives at risk. It will not accelerate quickly, could go up in flames, and does not go the speed limit on highways which are required for me to get home and to work. The recall was confirmed by the dealer as the check engine light flashed and caused a certain code to pop up for maintenance. The solution would be for Hyundai to fix the car, but they are refusing and saying the whole engine needs to be replaced now even though there's nothing wrong with the engine.

Over 3 years ago I went in for a normal oil change at Brookshire Hyindai Dealership where I was told my engine was consuming an alarming amount of oil. In order for Hyundai to do anything I was told o need to complete an engine oil consumption test which requires me to go back to the dealership every 1000 miles for 3k miles for them to check the oil. After completing this it was proven that there was a engine oil Consumption issue. They submitted it to Hyundai and I was denied. They said I needed to pay for an engine combustion cleaning which cost me about 400$, then I would have to repeat the test to see if the issue was resolved. After doing all of that, I still had an engine oil consumption problem according to the second test. Hyundai denied me again and told me I had to wait until my Engine light came on. So when it came on I brought it back, they said it wasn’t my engine according to the computer. I have spent thousands of dollars on oil over the past several years and Hyundai has done nothing. I do not feel safe in my vehicle. Hyundai has failed me. I then called Hyundai consumer care to open up a case and still nothing. All of that for them to tell me my extended warranty for my engine will not cover the issue. They have done nothing to resolve my issue only cost me time and money with no resolution. This is a known issue for my cars make and model and they are just turning their head the other way. Hyundai consumer care in fact does not care about consumers at all.

Our vehicle was towed to a Hyundai Dealership on July 26, 2025 (VIN [XXX] ) 2018 Hyundai Santa Fe to see if the engine falls under Hyundai's TSB #22-EM-001H-1Engine Failure Campaign. This vehicle has now been at Chapman Hyundai in Scottsdale AZ for over 5 weeks. We have yet to receive confirmation from Hyundai that any testing was done to see if the rods failed, thus having the engine fall under the recall. What we have received was a statement that “The engineering department did some tests and said that they didn’t think it was a rod issue, that it was due to lubrication not getting to the engine. When I asked for that data to be sent to me so I could review it with our long-time mechanic and my mechanical engineers that I work with, I was told that would not be possible, I just had to “trust” what I was being told. However, as a show of “good faith” in their unwillingness to provide us data, Hyundai was willing to pay for half of an engine replacement, leaving us on the hook for over $3,000 to the dealership. While I told the Executive Correspondence Department that that offer was not satisfactory, I did tell him we would be willing to pay $1,000 towards the replacement if Hyundai absorbed the remainder since on the above offer, I was paying retail while Hyundai is absorbing costs at wholesale prices. Five weeks on, we still have not received any confirmation as to the real issue of the engine failure, and frankly I have a hard time believing that any manufacturer would be willing to come up with the offer proposed if they didn’t believe the issue was substantially theirs. The company’s lack of willingness to provide data for us to review is very concerning and makes me think that the issue would indeed fall under the recall.

While I was dropping on the highway my vehicle suddenly slowed down when and the engine started shaking when I approached around 40mph and the check engine light started flashing. After checking I’m getting the error codes P1326 and P0014. I’m not unable to go past 40mph and the vehicle starts stalling when I approach that speed which is incredibly dangerous depending on what road I’m on. I’ve had zero issues with this vehicle previously and have always had regular maintenance. After researching other Santa Fe sport have had identical issues and there are recalls for other years but my year 2018 was skipped for some reason even though it’s clearly affected.

In May while driving on the highway my car suddenly wouldnt accelerate and started jerking. It would go past 60-65 and the engine light was on. Took it to get repaired and they stated the whole engine needed to be replaced. Never once had an issue with my car until then. Of course we got the runaround went it came to the warranty. After repairs I notice my car does not run the same and that its slow to accelerate. Fast forward about a month later the starter goes bad in the car and now its completely unoperable.
