2017 HYUNDAI SANTA FE Complaints

The contact owns a 2017 Hyundai Santa Fe. The contact stated that the tailgate and the hood unintendedly lowered after being raised and struck the contact. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not notified of the failure. The failure mileage was unknown.

For at least 14 months, the air bag light on the dash is on more often than not. The code that comes up on the OBD shows it's from the passenger side seat sensor. Occasionally, the seat belt indicator will flash when there is no occupant, as well. The car has never been in an accident, and the air bags have never been set off.

Sunroof exploded It sounded like a bomb went off and had my inside cover been opened I don’t know if I would’ve veered off the road been injured or injured someone else in the process. As it is I don’t know where the big huge piece of glass went. I do have pictures I reported it to my insurance company and also to corporate Hyundai. I was shaken up until the next day.

The vehicle’s engine is experiencing excessive internal oil consumption that poses a serious safety risk while driving. After a routine oil change performed by an authorized Hyundai dealer, the engine oil warning light illuminated within about 1,700 miles. Upon inspection by another Hyundai service center, technicians confirmed that the engine was burning oil abnormally and was three quarts low, with no external leaks. This issue was documented in the dealer’s repair order, which states “vehicle is burning excessive oil.” The problem has been reproduced and confirmed by a Hyundai dealer. The vehicle is equipped with the Theta II 2.4L GDI engine, which is already covered under Hyundai’s KSDS (Knock Sensor Detection System) extended engine warranty due to known internal mechanical defects such as bearing wear and oil consumption. Despite this, the manufacturer has declined to replace the engine. The excessive oil burning occurs rapidly and triggers the low-oil warning light while the vehicle is in motion, creating a risk of engine seizure and sudden loss of power that could lead to a crash. The defect remains unresolved. Warning lights for low oil level appeared multiple times beginning in 2025, shortly after the KSDS update and knock-sensor replacement.

Engine failure with no prior warning, such as oil pressure gauge,oil indicator light, or check engine light. Vehicle was at dealership for maintenance and this happened as tech was test driving. Found all oil was lost with no indications of a leak.

SPONTANEOUS PANORAMIC SUNROOF EXPLOSION - SERIOUS SAFETY DEFECT On October 12, 2025, at approximately 10:00 PM, while my 2017 Hyundai Santa Fe Sport was being driven on Interstate 85 near Greenville, South Carolina, the panoramic sunroof spontaneously exploded without any external impact or warning. What Happened: - My son was traveling at highway speed in normal driving conditions and he said it sounded a shotgun being shot at close range. The explosion created a period of dangerous distraction. - There was NO impact from road debris, rocks, or any external object - The sunroof suddenly and violently shattered, making a loud explosive sound - A few tempered glass fragments entered the passenger cabin, by the vast majority blew out of the vehicle. - The incident created an immediate safety hazard for vehicle occupants and for other vehicles who may have been following. - Visibility was not compromised, but due to glass exploding, my son had to drive on the shoulder of the Interstate at a slow speed with his hazard lights on in order to make it safely to an exit. Safety Concerns: - Sudden Loss of Structural Integrity - The sunroof exploded outward without warning - Glass in Passenger Cabin - Tempered glass fragments fell into the vehicle, endangering occupants - Driver Distraction - The sudden explosion and noise created a dangerous distraction at highway speed - Visibility Impairment - Glass debris and the sudden opening affected visibility - Weather Exposure - Immediate exposure to wind and weather elements at highway speed - Ongoing Safety Risk - This defect affects thousands of vehicles still on the road What Did NOT Happen: - No collision or impact with another vehicle - No road debris struck the vehicle - No rocks or projectiles hit the sunroof - No hail or weather-related damage - No recent sunroof operation or manipulation - No aftermarket modifications or repairs This was a spontaneous failure of a defective component during normal vehicle operation.

I bought this car a 2017 in December 2023. The first time I got the oil change they told me there’s no oil on a stick and then couple months later again no oil on the stick so I took it to my personal mechanic. He said there is an oil consumption problem so you advise me to take it where I bought it from. I had to go up there for 1000 mile test and then a 500 mile which I was low. Seems like every two weeks I had to put oil in it so where I brought the vehicle from told me to go to Hyundai. Hyundai only did one oil consumption test. I have a records of oil changes from Valvoline, my personal mechanic, Tradition Ford and one from Hyundai. Tradition Ford, where I got the car from with disappointment because I had a lot of proof that I was burning oil. There was no leak. There was no smoke at all. Besides it being under 10 years old, I was under 100,000 mile warranty and I had an extended warranty. tradition Ford where I bought it from took that one back however I lost $7000 from the down payment. I bought new tires for it, new battery, remote starter, spark, plugs, and rain guards. I still have all my papers from that vehicle 2017 Hyundai Santa Fe sport 2.4 engine liter.

Engine excessively burns oil. Failed oil consumption test. Hyundai denied warranty claim, citing maintenance neglect, despite oil change maintenance records and documentation.

The light for the passenger airbag has been on for years. I have taken it in, and the only thing the service department determined is that there was a water bottle under the seat. I was rear-ended into another vehicle, and the airbag did not deploy. The engine burns the oil from an oil change in approximately two weeks. I add a quart of oil every two weeks. If the engine seizes while driving due to this condition, I could be injured in an accident.

Engine is experiencing excessive oil consumption. Engine in question is a Theta II 2.4 GDI. Losing a qt every 400-500 miles. The car has less than 75,000 miles on it. The vehicle has been religiously maintained, oil changes every 5,000 miles or less. However because we are the second owners, even though it was purchased in 2020 when it had less than 30,000 miles, the warranty does not apply. The engine type has several manufacturer defects. Hyundai is using the technicality of a non-transferable warranty to get out of the fact that they knowingly put a defective engine in vehicles. By the time the oil consumption issue is apparent, it is too late, and you need a full unit replacement. I was quoted $9,000 - $10,500 by two Hyundai dealerships to replace the engine. I've spoken to non-Hyundai shops and the only way to truly correct the issue is to replace the engine with a remanned engine since the actual engines are manufactured poorly from go, so even a new one could be defective. There are million of these engines across several KIA and Hyundai vehicles. They cause undue burden to consumers. Hyundai and Kia do not stand by their product and consumers are being hurt. Instead of having an asset I thought was worth $10,000 an I could drive for several years and tens of thousands, if not one hundred thousand plus, more miles, I have a vehicle that is a ticking time bomb that would cost as much to fully fix the problem as it is worth. A simple google for Kia Optima, Kia Sorento, Kia Sportage, Hyundai Sante Fe, Hyundai Sante Fe Sport, Hyundai Sonata or Hyundai Tucson + Theta II 2.4 GDI will yield more than enough results to show how prevalent the engine failure + oil consumption issue is. If left unfixed the engine will consume too much oil and seize, or lead to other problems with vehicle rendering unsafe to drive.
