2017 Hyundai Santa Fe Complaints

Air compressor and compression failed engine diagnostic test. Vehicle had high oil and gas consumption.

Hi, my name is [XXX], i bought used Hyndai Santafe sport 2017 from dealership in 2020. It had around 47,000 Miles on it, intitially it was running fine but after driving 2 years i discovered that engine is burning oil and after the oil change right after 1000 miles i had to add a quart of oil and it was like every two weeks. I had many srevices from dealership and other auto mechanic stores but it didn't improved. I had no choice but to keep driving the card on XXX th the engine crashed with out any sign on dashboard. There was slight noise and it increase by the way car was parked on the side road from Highway. The car was towed to my local mechanic and confirmed that engine is crashed. After i had to towed to dealership and i am still waiting for their response. Now we have put 43,000 miles in 6 years (91,000) total mileage. I had bought the waranty from dealership by $ 2500 which expired in 2025 Currently no warranty. My question here is that the car is still under 100,000 and engin...

My vehicle experiences severe, unpredictable harsh downshifting/surging when slowing down, specially from 3rd to 2nd and 2nd to 1st gear. The transmission kick causes unexpected vehicle hesitation and deceleration changes in active traffic: presenting an immediate crash hazard. The dealership head technician has physically test-driven the vehicle and confirmed the failure. However, Hyundai Corporate is refusing to replace the failing transmission under 10 years/100,000 mile warranty because the vehicle's computer has not yet thrown an electronic error code. The manufacture is actively trying to force me to drive an unsafe vehicle until the transmission completely fails in traffic, putting my family and other drivers at severe risk. May 28, 2026 currently milage is around 88,000. The dealership currently has the vehicle.

reporting a serious safety concern involving my 2017 Hyundai Santa Fe Sport with the Theta II engine. While driving on the highway, my vehicle suddenly lost power without warning. The vehicle became unsafe to drive and I had to pull over and have it towed. There was no warning light before the failure. The vehicle has been regularly maintained. Hyundai later stated there was internal engine damage. My vehicle also shows an open engine-related recall/campaign since November 2025. I have found many similar complaints from other Hyundai owners describing sudden loss of power, excessive oil consumption, and engine problems involving the Theta II engine. I contacted Hyundai Motor America and provided documentation and videos, but I have not received a meaningful response. I am concerned this issue may represent a serious safety defect because the sudden loss of power occurred while driving on a highway.

The engine in my 2017 Hyundai Santa Fe Sport equipped with the 2.4L Theta II GDI engine is experiencing severe excessive oil consumption. The vehicle consumes approximately 2–2.5 quarts of oil every 1,000 miles despite multiple repair attempts and dealership-performed combustion cleaning procedures. Hyundai Motor America and the dealership documented the condition under PA #[XXX] and recommended engine replacement. Hyundai Motor America advised me in writing that the vehicle should not be operated in its current condition because of the excessive oil consumption and pending engine replacement. Excessive oil consumption creates a risk of sudden engine failure, engine seizure, stalling while driving, and potential engine fire if oil levels drop unexpectedly. Because the engine rapidly loses oil between normal service intervals, the vehicle may become unsafe to operate without warning, placing myself, passengers, and other motorists at risk. The defect was confirmed multiple times by Capi...
