2017 Hyundai Santa Fe Sport

I am the current owner a 2017 Hyundai Santa Fe Sport. While I was driving my SUV on the highway at highway speeds at 60mph, the oil pressure and the check engine warning light illuminated all of sudden after around 1 hour of smooth ride. In the meantime, suddenly the vehicle lost motive power, the steering wheel seized and smoke came immediately. Losing motive power in running conditions and smoke coming out during failure could have endangered our lives. The smoke came out due to leakage of engine oil probably. The vehicle was stuck in the middle of the road. The vehicle was towed to the residence and then after Hyundai Dealership. The dealer was made aware of the failure. The failure mileage was approximately 76,245 only. Before reporting to NHSTA I have seen numerous complaints about high oil consumption and burnt valves on Theta II engines around 2017 santafe sport model and very similar occurrence of events happening to all while driving the vehicle on highways. Hyundai must need to provide support to this year model and make vehicles.

The contact owns a 2017 Hyundai Santa Fe Sport. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power after the engine made an abnormal sound. The check engine warning light was illuminated. The vehicle was taken to a local independent mechanic to be diagnosed, but the cause of the failure could not be determined. The vehicle was not repaired, and the failure reoccurred. The vehicle was towed to a local dealer, where DTC: P1326 was retrieved, and the vehicle was diagnosed with knock sensor signal range error, metal shavings into the engine, and other unknown failures. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 67,000.

I am unsure what component of the engine caused the issue. There was chance of engine failure while driving. While idle the engine was stuttering and the RPN dial was fluctuating. Engine persisted to stutter and jerk at random intervals when accelerating. The engine light came on flashing ~1 hour after the first sign of the issue. Immediately after the engine light came on the vehicle was moved off of the road and a tow truck was contacted to transport the vehicle to a Hyundai dealership. The vehicle was inspected at a manufacturer's dealership and the problem was resolved with a technician stating that the vehicle needed a "system update". There is also an ongoing issue with the vehicle excessively consuming oil.

I have had this car since Sept 2023, it had about 85,000 miles when I got it. Before I had even owned it for a year and before it had 100,000 miles it was burning oil at an alarming rate! I took it to my dealership which did a consumption test and told me to bring it to Hyundai. Hyundai did their own oil consumption test which results proved my car was burning 3 quarts of oil in under 1,000 miles. Hyundai refused to do anything about it as well as the dealership I bought the car from (they say it is a Hyundai problem) I have spoken to corporate who refuse to fix it because I bought it out of warranty, which I was unaware of at the time I bought it. I am a single mother who has to work full time to support my family, my car has died numerous times and I am buying oil about once a week, I have had to call out of work due to it dying and it has died with my children in the car as well. I am afraid to drive it because I know it will die and I will be stranded but unfortunately I have no other options. It is a complete safety hazard and I can not trade or refinance because even tho I havent had it 2 years, I owe more than it is worth in value.

Excessive engine oil consumption. The vehicle oil consumption is beyond my control, currently I am afraid to embark on vacation driving to friends or on vacation in other states. Low engine oil can result in engine overheating and fire, thus endangering life, family and property. I am currently adding oil every 14 days to ensure the engine is at a safe operating level for my own safety. I am requesting a one time manufacture's assistance to remedy this defective.

Bought my vehicle as second owner and 1 1/2 years into financing I discovered the piston rings are failing which is causing to much oil consumption. It’s burning oil to fast - in three weeks my car has burned through three quarts of oil. I do my regular oil changes as recommended and already change the gasket. If I have not checked my oil I would never had a clue. I am currently doing my oil changes because the dealer shops were not nor even knew of the burning oil issue. How does one car burn that much oil in three weeks. My extended warranty has exited and now my engine is failing. My vehicle was not included in the class action settlement. I am a teacher with children and don’t have the money to buy a new car let alone fix the engine. The vehicle has rough idling at times and doesn’t have the power to go sometimes. It’s failing quicker than I could imagine.

Car stopped running 4 months ago and had it towed to the shop and they did a Knock sensor update and sent us back with it. 4 months later check engine light comes on and take it in and they recommend a new engine and this car has a class action and they’re saying we don’t qualify. They’re saying it’s the piston rings. The car burns oil like crazy. Over 5 quarts in 2,500 miles consistently and the oil light never comes on. I have 2 kids that ride in this car for it to just die or for the engine to start fire is a risk I am not willing to take.

This model engine is a common complaint easily found by quick internet searches. They have recalled SOME models, but not all. This car uses EXTREME amounts of oil. It is not normal. I have not had a car in my 38 years of driving that used anything even close. I do not have any leaks. This car requires 1 quart of oil every 500-700 miles. This is horrible for maintenance. It is very dangerous to an unsuspecting buyer. I found out about this when my engine light came on and to my surprise the oil was about empty after an oil change when I first purchased the car. This was only about 6 weeks in to having the vehicle! This is also horrible for the environment, expensive, and messy. Hyundai should be held accountable. The oil consumption is due to an engine defect that is not directly related to their current Lifetime limited warranty for connected bearing rods.

While driving my vehicle, the check engine light came on, and the engine entered limp mode, severely reducing power and acceleration. This presented a significant safety risk while traveling on the highway, especially during lane changes and merges. The issue was later diagnosed by a certified Hyundai dealer as Diagnostic Trouble Code (DTC) P1326, which relates to the knock sensor detecting potential engine bearing wear. The dealer confirmed this issue and performed related inspection work under Hyundai’s Service Campaign T3G. No prior warning signs appeared before the incident. Hyundai has issued a known campaign for this issue, but no recall appeared under my VIN at the time. I incurred rental and rideshare costs due to the vehicle being held at the dealer for several days. This condition severely impacts the drivability and safety of the vehicle.
