2017 HYUNDAI SANTA FE Complaints

My engine failed. Dealership put it through an oil consumption test which it failed. They ended up keeping my car for 3 weeks to build a new engine, add new belts, new spark plugs and new filters to go with the repair. After completing this repair they told me they noticed my air bag light on. They recommended a new sensor to fix it. Which I was to pay $600 for. I agreed to this and had it done. I picked up the car and had it for 3 weeks before the airbag light came back on. I brought it back to dealership. They assessed it and told me the problem actually came from the seat and the total.to repair the whole seat would be $2500+ I am the only owner of this car. It has never been in an accident where the airbag deployed. It is in it's original state. I feel this is a huge safety concern that should be looked into.

The contact owns a 2017 Hyundai Santa Fe Sport. The contact stated that while driving at an undisclosed speed, the vehicle failed to properly accelerate. The check engine warning light was illuminated. The vehicle was towed to the local dealer who determined that the engine oil was extremely low. An oil consumption test was started by the dealer however, the failure persisted. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 88,013.

What component or system failed or malfunctioned, and is it available for inspection upon request? Blown head gasket How was your safety or the safety of others put at risk? Engine overheated and coolant boiled in 110 degree weather. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes by Hyundai. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes by Hyundai. Hyundai states that engine needs to be replaced because the head gasket isn’t repairable on the 3.3L engine. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, engine overheated once and diagnosis was blown head gasket.

My vehicle we bought from carvana has been jerking/misfiring and now with no warning on freeway it wouldn't give power stalling. There was no warning nothing no lights came up. I drive my kids in this vehicle I've taken it to multiple mechanics they say they couldn't find why it's jerking and it must be a manufacturer issue. I looked online and yes lots of issues with the make and model recall about the crankshaft sensor cause these issues!!!

Subject: Urgent Safety & Warranty Concern – 2017 Hyundai Santa Fe Sport (TSB #21-01-002H) Dear Hyundai Customer Care and NHTSA, I am reporting a serious safety and warranty concern regarding my 2017 Hyundai Santa Fe Sport (VIN: [XXX] , mileage:97,320). The vehicle is exhibiting excessive oil consumption after an initial Consumption test burning 3quarts of oil in 725 miles as well as causing damage to the intake manifold requiring it to be repaired and is consistent with the connecting rod bearing defect covered under Hyundai TSB #21-01-002H. This TSB extends engine coverage to 10 years/120,000 miles for precisely this issue. Despite this, my authorized dealer, Premier Hyundai of Moreno Valley has refused to take immediate corrective action and is requiring me to drive an additional 1,000 miles before performing the repair — a delay that increases the risk of catastrophic engine failure and endangers vehicle occupants and other motorists. Key points: This is a documented defect with a known history of sudden engine failure. TSB coverage and my warranty should apply immediately, without dangerous delay. The dealership’s requirement to continue driving the vehicle is unreasonable and unsafe. I am requesting: Immediate authorization for the engine diagnostic and replacement under TSB #21-01-002H. Confirmation from Hyundai that I am not required to continue operating a defective engine to “prove” the defect. NHTSA to log this complaint as part of the ongoing safety concerns regarding Hyundai Theta II engines. Please respond within 5 business days with next steps. I am prepared to provide full maintenance history, documentation, and dealership correspondence. Sincerely, [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2017 Hyundai Santa Fe Sport. The contact stated that while driving at approximately 40 MPH, the "Low Oil" warning illuminated. The contact drove back to the residence and checked the oil level on the dipstick and became aware that there was no oil in the engine. The contact added 4 quarts of engine oil and drove the vehicle to the dealer. The dealer initiated an oil consumption test. The vehicle was taken to the same dealer three more times before the dealer determined that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure. The contact stated that the engine had been replaced two years prior due to excessive oil consumption. The failure mileage was approximately 160,000.

My vehicle is a 2017 Hyundai Santa Fe Sport AWD with a GDI Theta II 2.4L 4 cylinder engine. We purchased it in Feb. 2024 with 120,310 miles. Since then we have only put approximately 8,000 miles on it in 17 months. On Aug. 1st 2025 while driving up a hill out in the country the engine suddenly quit. Of course the steering and the brakes failed to operate. However I was able to coast to the next road and barely able to turn the wheel but made the corner and coasted to a stop. Without a nearby corner I would have been stuck on a state highway with many semi-trucks traveling on it. Could have been much more dangerous for my wife and I especially since we had to have the car put on a flatbed to be hauled home. The person who came to haul it checked the battery which was fine. You could hear the starter engage and try to turn the engine but it would not turn one bit. Once home we had a mechanic with many years experience have a look and listen to it. He could not get the engine to move even when trying to turn it by grabbing the engine belts and pullies. By all appearances the engine is seized. No warning lights were one and the oil was checked that very morning before leaving home. The vehicle was using about 1 qt of oil every 200 miles or so. Always used a high quality oil of proper weight/viscosity. Had no visible oil leaks on ground where it was parked every night. Hesitate to spend hauling fees to take it to the dealer 40 miles away if they are not going to do anything but offer to replace it for many thousands of dollars. For a couple living on social security this can absolutely turn things upside down as we only own one car (which we still owe on).

Motor replacement. I had taken my car several times into Hyundai for oil consumption issue. I replaced the recommended parts through Hyundai and ended up having to come right back after being stuck on the side of the interstate due to lack of compression two cylinder two I was told I needed to replace the motor. This has been a very expensive process and I haven’t had the car but 10 months.

Hyundai knows about the excessive oil consumption of these 2.0 Turbo GDI engines. My engine went out while driving my daughter down the road. Had to tow it to the dealer. Dealer is saying no compression on cylinder 3. Also a known issue. There was a massive lawsuit over engines already. Hyundai is no help. Excessive oil consumption has led to my engine going out. This needs to be investigated by safely board and Hyundai.
