2018 Hyundai Santa Fe Sport Complaints

I had my engine replaced in Nov 2024 due to excessive oil consumption. I was required to do an emissions update due to a recall on my car. Once the dealer did the update, it caused my check engine light to come on and now I need a new catalytic converter, which was all due to the excessive oil consumption. Hyundai dealer knows this but they are telling me I’m responsible for replacing it. It should be replaced by Hyundai not me. It was the issue with the engine.

2018 Hyundai Santa Fe Sport. Purchased January 2026 took to Oxmoor Hyundai Service Center March 2026. February 2026 began using oil at a measured rate of 700 miles per tank of oil. Used 3 full tanks of oil within the month of February. Oil lights and engine lights on and off and flashing during this time. March 8, 2026, engine light flashed and then stayed on continuously. Engine shook and stuttered and made a loud noise. Engine stalled while I was driving at 35-40 miles per hour. I was able to continue driving to my home with the stuttering and stalling. The next morning I drove it to the Oxmoor Hyundai Service Center. I told relayed the timeline of all symptoms I had experienced over the 2 month lifetime of my ownership. They did not attempt to reproduce the issue. They only entered "shakes in reverse" as the customer provided issue on the intake information. Service Center performed diagnostic, found cylinder misfires on cylinder 2 and cylinder 4. Replaced spark plugs to resolve Cyl...

TOOK CAR TO DEALER TO HAVE OIL CHANGED ON APRIL 29, 2026 AND WAS TOLD THEY HAD ALSO PREFORMED A SOFTWARE UPDATE, SERVICE CAMPAIGN 9C2. EVERYTIME SINCE THAT DAY AFTER THE CAR HAS SET FOR A LITTLE WHILE AND THE CAR IS RESTARTED DRIVEN IT STALLS AND SURGES REALLY BAD SEVERAL TIMES LASTING FOR SEVERAL MINUTES. IT ALSO CAN DO THIS AT RANDOM AT ANYTIME BUT NOT CONSTANT LIKE IT DOES WHEN FIRST STARTED. THIS IS VERY DANGEREST FOR OBVIOUS RASONS AND NEEDS TO BE FIXED. ALTHOUGH THERE IS OTHERS REPORTING THE SAME PROBLEMS ON LINE AND A PERSON MAKING THE SAME COMPLAINT WHILE I WAS WATING AT THE DEALERSHIP. THEY SAY "THEY ARE UNAWARE OF THE PROBLEM AND I WILL HAVE TO LEAVE MY CAR FOR UP TO THREE DAYS OR MORE TO HAVE IT CHECKED OUT AND THEN THEY WILL LET ME KNOW WHAT NEEDS TO BE DONE” AND WHAT THE COST WILL BE. I ONLY HAVE THE ONE VEHICLE AND THEY WOULD NOT PROVIDE A LOANER VEHICLE SO NEEDING MY CAR EVERY DAY I CAN NOT DO WITHOUT IT. DUE TO THE FACT THAT HYUNDAI REFUSES TO ACKNOWLAGE THE PROBLEM....

The engine valves and cylinders keep failing every 6 months. I have to spend another $1,800 to get it fixed. I doe this TWO TIMES last year. My car has the Theta 2 engine

While driving on the highway at approximately 70 mph with a heavily loaded vehicle, my 2018 Hyundai Santa Fe Sport 2.4L suddenly lost power and entered limp mode. The check engine light flashed and diagnostic code P1326 was stored. During limp mode the engine was banging hard, almost like it was seizing and then releasing repeatedly. This is consistent with connecting rod bearing failure, not wrist pin failure. P1326 is generated by Hyundai's Knock Sensor Detection System (KSDS), specifically designed to detect abnormal vibration consistent with connecting rod bearing failure — a known defect covered under Hyundai's Theta II engine warranty extension. Prior to this event the engine had been consuming oil abnormally. Approximately 1,300 miles after my last oil change the oil level had already dropped to the low mark on the dipstick, a significant change from normal operation. The vehicle was towed to a Hyundai dealership where it remains today. The dealership confirmed cylinder scoring...
