2016 Hyundai Santa Fe Sport

My car only has 93,000 miles on it. I was driving home from work and all of a sudden the check engine light came on while I’m on the freeway. I made it home and went to research then all of a suddenly the check engine light would just start flashing. I got it checked by a mechanic. They said that there was metal shavings in the oil which I have no clue how that would happen and that there was a code for knocking.

While driving the vehicle at approximately at 55 MPH on a the 826, the engine suffered a sudden and catastrophic mechanical failure without warning. The vehicle lost all motive power in active traffic, creating an immediate safety hazard and nearly resulting in a rear-end collision. Upon inspection, it was determined that the engine assembly, which is a replacement unit provided by Hyundai under the Theta II Settlement, with less than 12,000 miles, suffered an internal breach. This breach allowed coolant to contaminate the lubrication system sort of a milky oil, which led to a connecting rod bearing seizure. Despite this being a repeat failure of a safety-recall component and the vehicle being covered under the Theta II Settlement Lifetime Warranty, Hyundai Motor America has denied the repair claim. I am reporting this as a safety defect because the sudden engine stall resulted in a loss of power-assisted steering and braking while the vehicle was in motion.

The contact owns a 2016 Hyundai Santa Fe Sport. The contact stated that while the vehicle was parked and running, there was an abnormal fuel odor inside the vehicle. The contact exited the vehicle and inspected it. The hood was opened, and the engine cover was removed, and there was condensation dripping from the fuel pump. The contact’s brother inspected the vehicle and became aware of the strong fuel odor and the condensation dripping from the high-pressure fuel pump. The vehicle was then taken to a dealer, where it was diagnosed that the high-pressure fuel pump needed to be replaced. The vehicle was not yet repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

The engine light started blinking and my car would not accelerate anymore. I took it to the mechanic immediately, who said that there was an engine recall. I contacted the dealership, but they cannot do an initial inspection for more than 2 months. It would likely take another 2-3 months after the inspection before the engine can be replaced. I called Hyundai and they confirmed that my vehicle should be covered under an extended warranty based on the service history and error code from my car (TXXI for the Theta 2 engine - knock sensor detection, code p1326). However, Hyundai will not provide any help until the vehicle is inspected by a dealership. The dealership completely refuses to look at my car as they are busy. I live on an island, so the only other Hyundai dealership is two hours away. They will not answer any of my calls. I'm expected to figure out how to commute to work alone for the next two months, but since I live in a rural area, there are no alternative transportation options. An independent mechanic confirmed and reproduced the issue. The car is unsafe to drive. The dealer will not inspect my component in a reasonable time frame, much less repair it despite the fact that it is covered under extended warranty. The car was driving normally prior to the issue, and I did not notice any problems until the engine light started blinking. I have the car available for inspection.

I turned off the car and went inside the house. I was outside and could smell smoke. I walked to the front of the house and saw my neighbor who was calling 911 due to flames from my engine. The flames reached the yard and my garage where minor damage occurred. The vehicle was completely engulfed in flames before the fire department extinguished it.

The contact owns a 2016 Hyundai Santa Fe Sport. While driving at an undisclosed speed, there was an abnormal odor coming from the vehicle. The contact stated that the engine was consuming an excessive amount of engine oil. The vehicle was taken to the dealer; however, no cause for the failure was found. The contact stated that on a separate occasion, while driving at an undisclosed speed, there was an abnormal sound coming from the engine. The vehicle was pulled over to the side of the road; and the check engine warning light illuminated. A handheld scanner was used to retrieve DTC: P1326 (KSDS – Connecting rod bearings failure). The vehicle was towed to the residence, and then towed to the dealer. The dealer diagnosed the vehicle and informed the contact that the rod bearings had failed, causing engine failure. The dealer notified the manufacturer of the failure; however, the manufacturer declined to repair the vehicle. The manufacturer informed the contact that the prior owner had submitted a complaint regarding the failure in January of 2024. The vehicle remained at the dealer unrepaired. The failure mileage was approximately 132,000.

Six weeks ago the alternator and battery had also been replaced. My Hyundai Santa Fe Sport turbo engine, exhibited a persistent rubber-like odor for approximately three weeks after the latest maintenance. During this period, the push-start button intermittently failed, requiring multiple attempts to engage, and the vehicle experienced noticeable shaking. After being parked, smoke began to emerge from under the hood, followed by visible flames. Within roughly 3-5mins minutes, the vehicle was completely engulfed in fire and blew up 6 times. Notably, the car had undergone significant repairs in the past year, including an engine replacement, starter, OEM parts, O2 sensors, brakes, valve cover gasket, new tires, and routine oil changes.

September 3rd, 2025, my engine failed, for the second time and left me stuck at a busy intersection, in the middle lane and can't move. The first time my engine failed (2022/same vehicle), I was about the get on the highway and it just stopped in the middle of the road right before getting onto the highway. Both times I've had to get out in traffic in order to move my vehicle. I'm causing a stop to traffic or a stop in the flow of traffic. In September when this happened, I had cops, mechanics and pedestrians stopping to help (thank goodness), but that caused a stop in the flow of traffic. Any of us could have been struck by a vehicle. It was also around 10/11pm at night There is an open recall on my vehicle and more specifically, the Theta II engine in my vehicle. It does not show when my VIN number is put in, but it's nationally known that there is an open recall and also a class action suit that was just settled in 2021 granting all customers with "Class vehicles" a lifetime extended warranty on the engines. They make it so that it's not that easy to just search and see there is a recall, but there is. My car has been at the Hyundai dealership since 9/4/25. So, yes it has been inspected by the manufacturer, and they confirmed that the diagnostic came back as positive for the recall. Yes, my check engine light would come on and off starting the end of 2024. Starting in April of 2025 I started having smoke come out of my exhaust and oil burning in days. All the while I have no puddle of oil underneath my car. I took it into Hyundai at that point, and they told me until my engine light was flashing and my car had stopped, they wouldn't be able to do anything in regard to the engine. Now my car has been there, I've provided service receipts that show proof of regular maintenance, I have the KSDS system installed, and they are denying my claim to replace my engine.
