Hyundai Santa Fe Sport engine failure problems

Filed Nov 1, 2026 · Engine · WA

While driving my engine seized up and my car completely stopped. I was luckily able to coast it to the side of the highway without getting into an accident. I had it towed to Go Hyundai in [XXX]. The did the diagnostic, found it was covered by the recall and allegedly ordered the engine. The engine is apparently on back order and has to come from [XXX]. They are dragging their feet in providing me with alternative transportation. Because I don't have a credit card I'm not able to use their loaner vehicles or rent a car myself from a car rental company. I am having to pay every day to go to and from work in Ubers. I can't continue to afford this and Go Hyundai is acting like it's MY problem the engine failed. Hyundai has been contacted directly but there doesn't seem to be much they can or will do either. I'm running out of money and without a vehicle I can't get to work. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Started car to reverse out of parking space and it started jerking as I accelerated. Drove jerkily the few blocks I had to go to make it home. Did not drive again but upon starting it the check engine light came on. Contacted Hyundai customer care who told me my car was covered under two extended warranties for a well documented engine failure on this exact vehicle - Hyundai Santa Fe Sport 2017. I’ve been researching and Hyundai knows about this problem and it had been through the courts after group legal action was taken. Hyundai refuses to pay for the car they know is a failure to be diagnosed. I cannot afford to have the car diagnosed especially not for a problem that Hyundai and half the world know (and have documented) is Hyundai’s fault. Vehicle can not be driven.

There was a low noise when I got in the vehicle in the morning. I looked at the engine and it was coming from the abs system. I took it to the mechanic shop and the noise was even louder, the abs part on the passenger side of the firewall in the engine blew up and catch fire. Luckily they were able to put the fire down right away. I’m glad that didn’t happen while driving or while in the driveway of our house were there’s more vehicles parked. There was an Abs light on the dashboard due to an abs sensor for the rear right wheel.

I was driving my car and it showed no signs of any issue but the engine light came on and started blinking so I pulled over and got it towed to a mechanic. He told me that I would need a new engine that would cost me $8000. I looked into it and found that there was a defect with my vehicles engine and that if I took it to a dealership, I could possibly get it covered 100% so I did that and then they covered it and when I got the vehicle back, it had an issue every time I drove it where it was kind of speeding up and jerking when I drove it, I took it back after I told them what happened and then they told me that my catalytic converter was bad and needed to be replaced. I ended up paying $1500 to get that replaced and when I got the car back again it’s still jerking and doing the same exact thing even worse. I contacted them. They told me to bring it back which I did and they told me that it needed a software update that was not available so that I would just have to be patient. They told me that anytime I wanted to drive it I had to let it warm up for 5 to 10 minutes and that it wouldn’t do that. I’ve had my vehicle back for over two weeks and it doesn’t matter if I warm it up or not it’s still doing the same thing. I do not feel safe driving this vehicle and I have not been giving any resolution by either the dealership or by the consumer affairs case manager that I have been working with on this. This has been an ongoing issue for three months now. It’s costed me hundreds of dollars in Ubers because I don’t feel it’s safe to drive.

My 2018 Hyundai Santa Fe is burning oil and I run the risk of engine failure. I have to check my oil level daily. The mechanic who performed my last oil change said he is seeing this frequently with this age Hyundai Santa Fe. He said Hyundai should be willing to replace my engine but of course they won't. I fear that I am going to be on the freeway and have sudden engine failure creating a risk for me and drivers around me.

While driving over the pass the car suddenly lost power and was running very rough. Luckily there was an exit close by that we took and the engine died on the exit. We were able to get it started and get to a parking lot where it died and would not start again. While trying to start it in the parking lot the check engine light came on. So, after a $375 tow to the nearest town the mechanic discovered a damaged spark plug and the compression test showed 0 psi. The scope showed a hole in the piston. The car also leaks and burns oil. The mechanic recommended scrapping the vehicle since it would not be cost effective to repair it. The mechanic said ours is the 6th Santa Fe in their shop with a blown engine in the past month. It has not been inspected by anyone else.

My 2018 Hyundai Santa Fe Sport (2.4L Theta II GDI, VIN [XXX], approx. 110,000 miles) has suffered a chain of engine and emissions-system failures that create a loss-of-power safety hazard. At about 80,000 miles, Hyundai replaced the original engine under warranty for excessive oil consumption, a defect Hyundai has acknowledged across the Theta II engine family. After only about 20,000 miles on that replacement engine, the catalytic converter failed and set a P0420 code. The vehicle now bogs down, hesitates, and loses power under acceleration. This is dangerous when merging or accelerating into traffic, where a sudden loss of power raises the risk of a collision. A restricted or failing catalytic converter causes exhaust backpressure and abrupt power loss, and the underlying oil consumption also risks low-oil engine damage and stalling. A catalytic converter should last far longer. This premature failure is consistent with the well-documented Theta II pattern in which engine oil consumption contaminates and destroys the converter substrate. It indicates the replacement engine Hyundai installed is itself consuming oil and damaging downstream exhaust and emissions components. I reported this to the dealer and to Hyundai. Hyundai declined to cover the catalytic converter, treating it as unrelated, even though its own warranty engine replacement is the direct cause. I am filing so this safety-related failure is documented. No crash, fire, or injury has occurred. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2013 Hyundai Santa Fe Sport is subject to Hyundai Recall 162 / the federal safety agency Recall 17V‑226, concerning premature connecting-rod-bearing wear that can cause engine knocking, engine failure, and loss of motive power. My vehicle developed engine knocking and a flashing check-engine light while I was driving. The vehicle is now at an authorized Hyundai dealership. Hyundai initially denied an engine replacement based on mileage. I escalated the matter to Hyundai Motor America Corporate Consumer Affairs. Hyundai has now confirmed in writing that, because my vehicle is more than eight years old and has more than 150,000 miles, Hyundai is applying the high-mileage provision of the Theta II settlement and will not replace the engine. Instead, Hyundai is offering either a repurchase or $2,000 in lieu of engine replacement. I understand that Hyundai is relying on the court-approved settlement. My concern is specifically whether Hyundai’s application of that settlement to my vehicle is consistent with the administration of Recall 162 and the federal safety-recall remedy, given that my vehicle is experiencing the engine failure that Recall 162 was designed to address. I am requesting the federal safety agency’s review of Hyundai’s handling of this safety-related recall matter.
