2018 Hyundai Santa Fe Sport problems

“This vehicle has been suffering from substantial engine oil consumption, burning oil at an alarming and unsafe rate. I have repeatedly brought the vehicle to Washington Hyundai to address this under the engine class-action lawsuit terms, but the dealership continues to run repetitive tests without a resolution. This is a critical safety issue. Excessive oil consumption poses a severe risk of sudden, catastrophic engine seizure or stalling while operating at high speeds on the highway.”

“The contact owns a 2018 Hyundai Santa Fe Sport. The contact stated that while attempting to start the vehicle, several warning lights illuminated and the ABS message was displayed. The dealer was contacted and made aware of the failure. The vehicle was scheduled to be repaired. The contact referenced a recall with a similar failure; however, the VIN was not under recall. The contact stated that the vehicle was unsafe to drive. The manufacturer was contacted and made aware of the failure. The failure mileage was approximately 56,000.”

“Bought this as a used vehicle with around 77k miles. The SUV was running fine for a little while until I drove onto the highway. It eventually began to bog down and there was hesitation and jumping instead of acceleration. This continued my entire trip home with the check engine light on. The car was only driven for about 300-400 miles in the time I had it. When I brought it to have an oil change, they found metal shavings in the oil. From what I’ve been reading, this has been a common problem for this vehicle. It has been sitting in a Hyundai service center for at least a month now with no real responses from Hyundai themselves. They told me they would not fix the problem due to lack of maintenance from prior owners and that they were marking my title (doesn’t make sense since I bought this with a clean title). According to what Hyundai told me, this issue was brought up by a previous owner in January 2026 with no repairs. How can you change the status of my title while refusing to repair a problem caused by a manufacturers defect?”

“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 Cylinder 2. Cylinder 4 continued to misfire. Used Borescope and found broken valve. They did not address the scoring on the cylinder of the valve. Recommended engine replacement.…”
