I do not understand how Hyundai can approve its required testing process, have the vehicle fail that test, and then deny the engine replacement resulting from those findings. This is unfair and raises serious concerns about how Hyundai is applying its warranty procedures.Hyundai’s published oil-consumption procedures establish a process for diagnosing excessive oil consumption and determining when further repairs, including engine replacement, may be warranted. I am requesting that Hyundai explain exactly what requirement my vehicle allegedly failed to meet and provide documentation supporting the denial.I am requesting that Hyundai reverse the denial and fully cover the necessary engine replacement under warranty. I also request a complete review of my maintenance history, repair records, oil-consumption test results, diagnostics, and the dealership’s submission. This vehicle has been properly maintained and has only approximately 80,000 miles. I purchased it expecting a reliable vehicle that would last many years. An engine developing excessive oil consumption at this mileage is unacceptable, and I believe Hyundai should stand behind its product and warranty obligations.

While being inspected at the dealership, multiple fuel injectors (#1 and #3) were found to be leaking. This presents a severe fire hazard as fuel is escaping onto engine components. The dealership confirmed the leak and suggested replacing all six injectors due to potential systemic failure, but the manufacturer (Hyundai) is refusing 100% coverage. I have been without a vehicle for over a week, and this is a critical safety defect that could lead to an engine fire or stalling while driving.

Our motor has been consuming a lot of oil, we were told that Hyundai knows about the issue and that there is nothing they can do. We got sold a poor excuse of a warranty in which they never told us that the warranty would not cover oil consumption, but we have the “best” warranty they had. Our car has died GOING DOWN THE ROAD WITH MY 4 kids and WIFE! Cars had to swerve to avoid a collision, 5 times this has happened but yet they will not do anything! We will be seeking legal help!

Seat belts does not retract and when pulled it remains in that position. Even when I feed the belt back into its place its very loose and unsafe.[driver seatbelt], fuel injectors are causing the car not to accelerate and safety concerns while on freeway with children the car began to shutter/wanting to.shut off. I used both break and gas at the same time to keep the car running. I was told by Hyundai that the powertrain warranty purchases does not cover that part.

While merging onto a highway, my 2020 Hyundai Palisade abruptly lost all engine power and stalled. This immediate and complete failure occurred at a critical moment, posing an extreme safety risk. All dashboard warning lights illuminated, but provided no specific diagnosis. The vehicle was towed to a dealership, where technicians determined the engine was consuming oil at an abnormal rate, despite a lack of visible leaks. I was instructed to participate in an "oil consumption test," a three-part process that required multiple oil changes and inspections over several months. Each time, the vehicle had burned over a quart of oil—a clear indication of a defect. Despite this evidence, Hyundai denied my warranty claim, accusing me of negligence for being unable to produce oil change records between 29,600 and 46,900 miles. This is a common and unacceptable tactic used to avoid accountability for a widespread issue. My experience is not isolated. Hundreds, if not thousands, of owners of 2020-2023 Hyundai models, including the Palisade, report identical engine oil over-consumption issues and subsequent power loss. This issue is a **severe safety hazard** that can lead to sudden, catastrophic engine failure and potential accidents. Hyundai's refusal to acknowledge this defect and issue a recall is **gross negligence**. They are knowingly allowing thousands of unsafe vehicles to remain on the road. There are currently federal lawsuits against Hyundai for this very issue. The transportation authority must force Hyundai to issue an immediate recall and remedy this critical defect before a tragedy occurs.

On [XXX], while driving on the freeway, my 2020 Hyundai Palisade suddenly malfunctioned and went up in flames without warning. My young son was in the vehicle with me. Within moments, smoke and fire spread rapidly, forcing us to stop in traffic and escape before the fire fully engulfed the car. The entire vehicle became a total loss. This was a terrifying, life-threatening situation. My safety and my son’s safety were at extreme risk. If my other family members had been in the car, the outcome could have been catastrophic. The emotional trauma from this event is significant and continues to affect us. The incident was reported to the San Antonio Fire Department, who responded to the scene and documented the fire. Their reports confirm the vehicle fire: Incident Report #[XXX] and SAFD Case #[XXX]. After researching, I discovered that similar fires have been reported in Hyundai vehicles, raising concerns that this is part of a wider safety defect. Families should not have to fear their vehicle spontaneously igniting on the road. At the time of the fire, there were no warning lamps, error messages, or symptoms that suggested the vehicle was unsafe. The failure happened suddenly and without warning. The vehicle has not been inspected by Hyundai at this time, but it is available for inspection upon request. I am urging a full investigation into Hyundai’s design and safety practices, as this fire placed lives in immediate danger. This was not just a mechanical failure—it was a potentially fatal event that could have resulted in severe injury or loss of life.

UNKNOWN. Rough idling. Throwing itself into park & turning the engine off but dash stays on like engine is running. Engine, oil, battery, theft light does come on when this happens but go away after starting car. Has been to mechanic multiple times but showing no codes & unable to figure out the cause of it. The car can not just idle either. Has been going on for over 6 months.
