2017 Hyundai Santa Fe

The contact owns a 2017 Hyundai Santa. The contact stated that while driving at approximately 55 MPH, the vehicle stalled and hesitated to accelerate while the accelerator pedal was depressed. The check engine and check engine oil warning lights illuminated. The vehicle was taken to a local O'Reilly's, where it was diagnosed with ignition coil #3 misfire. The vehicle was not repaired. The vehicle was towed to an independent mechanic, where it was diagnosed and determined that the engine needed to be replaced due to severe engine oil consumption. The vehicle was then to a local dealer, where it was diagnosed with abnormal engine oil consumption, and the dealer determined that the engine needed to be replaced. The vehicle was not repaired. The contact stated that the vehicle required an engine oil refill 800-1,000 miles before an engine oil change was due. The contact related the failure to several unknown Hyundai TSBs. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 87,000.

While driving home on the highway from our sons hockey game at about 8:30 pm we were going about 60 mph when the car made a noise and began smoking and as we were trying to pull over on the side of the highway noticed by the reflection of a passing car that the engine on our vehicle was on fire under the vehicle. We had to evacuate the vehicle quickly and get our children out on the side of a busy highway with fire showing under the front end of the car.

The steering left side electrical components quit working at the same time without warning. This is all related to the Air Bag clock spring a serious safety defect that disables the airbag and possibly horn. I have taken the vehicle to a Hyundai dealership for diagnostics and this is what was found. "Needs immediate attention [Primary]: SSD : STEERING OR SUSPENSION DIAGNOSIS Air Bag - Clockspring Assembly / Spiral Cable: CLOCK SPRING HAS SHORTED OUT CAUSING ALL THE BUTTONS ON THE LEFT SIDE OF THE STEERING WHEEL NOT TO WORK This assembly consists of a clock spring, which is a coil that retracts and expands inside its housing as the steering wheel turns. Its function is to maintain electrical continuity for all the components on the drivers airbag.

My wife's 2017 Hyundai Santa Fe Limited experienced a sudden crack in the engine and lost oil without any warning signs. There were no warning lights, no check engine light, and no unusual noise before the engice crack. A certified independent mechanic inspected the vehicle and confirmed the engine has no oil, whick it did a couple days before when I checked the oil and topped it off, which is the same issue described in Hyundai’s known engine safety recalls. I was never notified of any safety campaigns or recalls. I am not the first owner, so the required recall inspections and updates were never completed on this vehicle before I bought it. The sudden engine crack and loss of oil created a serious safety risk, especially because there was no warning before it happened and it almost left our family stranded two hours from home. This failure matches the symptoms described in Hyundai’s Theta II engine defect investigations. While at the mechanic shop, we were quoted $10,000 to get a new remanufactured engine put into this car. I certainly (and I know most families) don't have $10k sitting around waiting to be used for car repairs. I am requesting that NHTSA investigate whether this vehicle should be included in the affected group, and whether this engine failure is part of the broader safety defect already identified in many Hyundai engines from the same model years. This vehicle is currently parked in our yard waiting to be repaired or sold. I would prefer it be repaired by Hyundai since one of the car plants is only 1 hour from our house. I was unaware of the current safety recall until I read it today.

Seem like there was a recall on the 3.3L engines on the Hyundai Santa Fe starting January 26, 2017, for engine related knocking noise. My Vin is [XXX] according to the Manufacturing plate it was made in Korea released on January 04, 2017. I realize it is a 22-day window on the recall but after an oil change the motor has started knocking the oil is the right viscosity, full to capacity, and oil filter changed. I drove 200 miles after an oil change then the motor started knocking. Is there a certain stamp on the cam shafts to verify which of the 420 vehicles are affected by this recall?

My 2017 Hyundai Santa Fe Sport 2.0T (Theta II 2.0L GDI Turbo engine) has been diagnosed with burned exhaust valves requiring a complete engine replacement. This is the second catastrophic powertrain failure on this vehicle in under two years. In July 2024, I paid $2,754 to replace the turbocharger at an authorized Hyundai dealership (Wright Hyundai, [XXX] ). The burned valves are consistent with carbon buildup on intake valves, a widely documented and known deficiency of the GDI fuel delivery system used in the Theta II engine family. Carbon deposits restrict airflow, cause valve seating issues, and lead to valve failure. This is an inherent design characteristic of the engine, not a maintenance-related failure. At no point during my ownership — including during the turbocharger repair — was I informed of this known issue or advised of any preventive measures such as fuel system cleaning treatments. I am additionally concerned that the dealership's diagnostic process was incomplete. The service center diagnosed the burned valves and immediately recommended an engine replacement without performing a bearing clearance test or completing the full diagnostic flowchart. The dealership has refused to perform further diagnostics unless I pay additional fees, and has refused to share documentation from a tech line case opened with Hyundai corporate. Because diagnostics were halted at the burned valve finding, a connecting rod bearing failure — the specific defect covered under the Theta II class action settlement (In re: Hyundai and Kia Engine Litigation, NoXXX) — has not been ruled out as a contributing cause. Hyundai's National Consumer Affairs office (Case #XXX) denied my goodwill request without addressing either the known GDI carbon buildup issue or the fact that this is the second catastrophic failure on this engine platform. This vehicle has approximately 86,000 miles. I purchased it as a second owner in August 2020 at 42,730 miles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 5

On my Driver/passenger seat the recline switch with not go back only forward. The dealer explains to me that just diagnosing the issue is 250 then the switch is going to cost me over $800. If replace the Power Seat Switch for $49.99 and the Power Seat Switch Knob only cost $ 15 plus dollars, also to replace the motor $200-300 now my air bag light is on not sure if it's because of the seat functioning or not, my kid's car seats are right behind the seats so its concerning to me. Looking online they are hundreds of people complaining of this, but no action has been taken such as a recall.

The contact owned a 2017 Hyundai Santa Fe equipped with a Rockland Electric Mobility Scooter Lifter, Part Number: 10101194. The contact stated that after the mobility scooter lifter was installed on the vehicle, the vehicle experienced electrical failures. The A/C became inoperable, and the hatch opened intermittently. The contact stated that while the vehicle was parked approximately a month after the lifter installation, the alarm sounded intermittently during the day. The contact observed the vehicle from the residence, but did not notice any abnormality. The contact installed the mobility scooter on the vehicle in the evening. The contact stated that the vehicle alarm sounded at night, and the contact noticed that the vehicle had caught on fire and there were flames coming from underneath the hood by the engine and firewall location. The vehicle was significantly burned from the front end to the trunk. The fire was extinguished by the fire department. A fire department report and a police report were filed. There was no property damage. There was no physical injury sustained. The contact sustained mental trauma, causing headaches and the right side of the lip to quiver. The contact had called Gregory Fox, an investigative reporter and anchor at WESH 2 News(NBC), who notified the manufacturer of the failure. The manufacturer followed up with the contact and informed the contact that a third-party investigation would be conducted to determine the cause of the fire incident. The vehicle was towed to a salvage yard, where a third-party investigation was conducted, and the manufacturer informed the contact that the fire was caused by the Rockland Electric Mobility Scooter Lifter. The vehicle was totaled. The failure mileage was approximately 63,000.

On April 2, 2026, the engine in my 2017 Hyundai Santa Fe failed catastrophically while my wife was driving. The vehicle lost power suddenly and completely. There was no warning and no prior symptoms. She was able to pull over safely in a residential area. The vehicle was towed to an authorized Hyundai dealer, where the service representative suspects connecting rod bearing failure—the same failure mode described in NHTSA recalls 17V226 and 17V578 affecting other 2017 Santa Fe vehicles with the Theta II 2.4L engine. The engine is available for inspection upon request. My VIN does not appear in the recall population, yet the failure is identical to the documented defect. This suggests the recall scope was insufficient. One week prior, we drove this vehicle on a 500+ mile family road trip with our child. The failure that occurred could have happened at highway speed. We are lucky to be alive. No warning indicators appeared before the failure. The vehicle has been regularly maintained. The problem has been preliminarily confirmed by the dealer as suspected bearing failure, pending teardown.
