2018 Hyundai Santa Fe Sport

Q1. The car is shaking and making rumbling noises upon driving and a check engine light is turned on. It seem like the car will abruptly stop and may result in a crash on a highway. Inspection by multiple mechanics indicate that the engine is misfiring and there seems to be an engine oil leakage issue, imbalance of engine or some part of it. The engine configuration is the same as with the engine recalls (under recall number-17V226000) made on 2013 and 2014 models of Hyundai Santa Fe sport which is GDI, 2.4 Liter and was also manufactured in the USA. Yes, the car is available to inspect on request. Q2. The car was shaking and rumbling while driving even at 40mph. We had to pull up to the side because it felt risky and then had to drive slowly to reach home. It was scary and felt life-threatening with a risk of crashing due to abrupt halting of the car. Q3. Yes inspected by the manufacturer- Hyundai. Q4. The check engine light has been coming on and off for over 10 months period. The car has been inspected and checked by multiple mechanics including 2 times visit to the Hyundai service center. They first appeared in Oct 2023 and is an ongoing issue every other month costing me ~$1000. I have been filling up with 4 quarter of engine oil after driving ~200 miles since it was suspected to be an engine oil leakage issue. However, nothing has been resolved and this issue fits the description and problems seen the Hyundai 2013 and 2014 Santa Fe sports- which have been recalled (under recall number-17V226000).

Driving on the highway my Hyundai begins braking and cannot be stopped even though the Automatic braking system was disengaged. Dealt with the dealerships and they all provide no help at all. I have brought this to two different dealerships and they just have excuses. This is a known issue with Hyundai and needs to be addressed.

The oil light has appeared to light up in the car while I am driving it. The first time was January 2023. I pulled over and checked my oil and had literally no oil in my car. I immediately went to Auto Zone (or Advance/O'Reilly's-I'll check my receipts) and poured 5 quarts of oil in the car and called Hyundai (this was within the timeframe of oil changes). They had me bring my car in and stated they needed to change oil and do an oil consumption test, so I had to drive 1,000 miles, bring my car back in and repeat. In the end, they said nothing was wrong with my car. In early August, this year, the same thing happened and I am having to go through this again.

The contact owns a 2018 Hyundai Santa Fe Sport. The contact stated that the vehicle was consuming an abnormal amount of engine oil. No warning light was illuminated. The vehicle was taken to a local dealer where an oil consumption test was completed, and the results were that the vehicle was consuming one quart of oil for every 640 miles driven. The vehicle was not repaired. In addition, the contact stated the dealer contacted the manufacturer to request that the engine be replaced; however, the manufacturer declined to approve the engine replacement due to previous services being performed by independent mechanics. The manufacturer was made aware of the failure. The failure mileage was approximately 50,000.

I got my oil changed 98,161 March 1 2024 at mechanic shop Mechanic shop checked oil March 29 2024 at 98,867 a total of 706 miles driven since last oil change. They added 2.5 quarts of oil. So i did my own research online found out the Hyundai 2018 Santa Fe Sport Turbo 2.5 Theta engines has excessive oil consumption problems that will cause Engine to seize/lock up, catch on fire, and other mechanical problems. I have an extended warranty TXXI and TXXC. Oil consumption leaks into the pistons and rod bearings and will cause a knocking in the engine. The oil is already in spark plugs and pcv valve which i replaced. But it will continue to keep happen over and over. I don't want my engine to catch on fire with me in it or at all that's why i am proactive in getting this solved now its already a problem. I contacted Wilson Hyundai dealership they did an 2 month oil consumption test Oil change i had to drive it for 1000 miles It failed. Then they did combuster chamber cleaning i had to drive it for another 1000 miles it failed again. So they submitted claim to corporate that i needed an engine. Corporate declined saying i was over my miles they had the wrong mileage it was a way just to deny me but dealership had correct miles so they could not follow through with that lie. So Corporate made Dealership send another claim in this time corporate denied it saying i was over my warranty. No i was not i started this at 98, 867 miles When 2.5quarts had to be added. I also had to wait a week to get into Wilson dealership because they were backed up in appointments i was at 100,212 miles and so where other Hyundia dealerships others were 1-2 months out in appointments. I had to be in a rental car for 2 months had to pay for it and still pay car note paid for oil testing which i was told i would be reimbursed for repairs and car rentals but they did not honor it nor did they pay goodwill pay for all of my inconvenience 2 month long testing and it failed and they still denied/ lied

I am writing to formally file a complaint regarding the significant oil consumption issue with my 2018 Hyundai Santa Fe Sport. My vehicle was part of a class action lawsuit settlement that provided extended warranties and reimbursement for repairs related to oil consumption defects. I first reported the oil consumption issue in 2022, while my vehicle was still within the warranty period. Despite my multiple attempts over the past two years to have an oil consumption test conducted, Hyundai dealerships only agreed to perform the test in January 2024. The test confirmed that my vehicle has an oil consumption issue. However, Hyundai has refused to cover the necessary repairs, claiming that my vehicle is now past 100,000 miles and out of warranty. This refusal is unfair, as the issue was acknowledged within the warranty period, and the delays in testing were beyond my control. I must consistently add oil to my vehicle several times a month and get oil changes before the recommended timeframe to ensure the vehicle runs smoothly without damage.

The contact owns a 2018 Hyundai Santa Fe Sport. The contact stated that while driving at an undisclosed speed, the contact observed smoke coming from the engine compartment. No warning lights were illuminated. The vehicle was taken to the dealer, and after an oil consumption test, it was determined that the vehicle was consuming an excessive amount of engine oil. The contact was informed that the engine was consuming 2-quarts of oil every 700 miles and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 100,000.
