2017 HYUNDAI SANTA FE Complaints

Driving on main road , car came to complete stop while waiting on traffic light and vehicle loss power , and wouldn’t accelerate. No , dash lights nor sounds were on prior to it loosing power nor stalling .

I am reporting a sudden engine failure involving my 2017 Hyundai Santa Fe Sport 2.0T. At just 68,000 miles, the vehicle experienced catastrophic loss of power due to zero compression in Cylinder 1. The vehicle is equipped with the Theta II turbocharged engine, which has been the subject of previous investigations and safety recalls due to premature failure risks, including stalling and fire hazards. This failure occurred on [XXX], while I was driving on the highway. There was no warning. It put all drivers near me at risk as I had no power, was traveling in the left lane and had to navigate through 3 lanes of traffic to reach the breakdown lane. I request that this case be investigated further as a potential safety risk and recurrence of known issues with this engine type. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This vehicle has experienced numerous serious failures, including two engine replacements, a transmission replacement, and persistent safety system malfunctions. The Downhill Brake Control (DBC) system remains stuck in the "on" position, and the traction control warning light stays illuminated. These issues directly compromise vehicle safety and stability, particularly on hilly or wet roads. Despite extensive service at Arapahoe Hyundai in Centennial, CO, these problems continue to return. The vehicle has been in the shop multiple times and was most recently in service for nearly 30 days. My wife was stranded at the dealership today due to the same unresolved safety system failure. Dealer communication has been poor, and repairs are often incomplete, requiring immediate return visits. The repeated failure of safety-critical systems, combined with the inability to resolve the issues long-term, presents a significant safety concern for both my family and others on the road. I am requesting NHTSA to investigate whether this is part of a broader defect pattern affecting 2017 Hyundai Santa Fe models and if a recall is warranted.

The contact owns a Safety 1st safety seat, Model type: Grow and Go All-In-One-Convertible, Model number: CC31-GYY, Manufacturer Date: August 01, 2023. The contact stated that the cloth part that covers the headpiece does not fit. In addition, the insulation part inside the cloth will detach. Most recently, the contact stated that the harness that goes across would become difficult to buckle. It would take several attempts to make it secure. The manufacturer was not notified of the failure.

The car has been consuming all the engine only after 700 miles. This has been a constant issue since December 2024 and the issue has been brought up with Hyundai dealership in Denville, NJ and Hyundai Corporate as well. Hyundai dealership in Denville, NJ performed 2 oil consumption tests, which the vehicle failed both test only after 700 miles as it consumed all the engine oil. They refused to do further investigation or recall the engine as it should be covered under Hyundai TXXI warranty given the Hyundai Engine II Class Action Settlement a few years ago. The vehicle has broken down on me on the highway a few times and has put my family at risk and danger due to the negligence of the Hyundai dealership in Denville, NJ and Hyundai Corporate refuel to resolve the issue. Now the car does not start at all some days thus it has impacted my work and my ability to provide for my family

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.

Excessive oil consumption/ burning oil; oil light came on 1,500 miles after oil change.

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.
