While driving down the highway at 65mph my 2016 Santafe Sport experienced engine failure. We sat on the side of the highway, next to an on ramp with high traffic beside a cement wall. When the tow truck arrived the driver was nearly ran over! There was no way to get the car to a safer location. After being towed to the dealership they said the engine failure would be submitted under warranty due to an issue with the connection rod bearing damage causing the engine to fail. It was denied because I was not the initial owner. A week later I received information about a class action suit against Hyundai for this very problem. As part of the suit they had extended the warranty. The dealership resubmitted my information and it was turned down again, this time for high mileage. Several months later the dealership wanted my car removed from their property, I asked them to submit it again. This time turned down because the KSDS was not updated prior to the engine failure. I now have a like new vehicle that I owe $9,000 on with a known defect that was never corrected because the required KSDS update was listed as a service campaign rather than a recall and so went unnoticed by the dealership I bought it from, or the NY inspection centers during my annual inspection and unknown to myself because when I checked for recalls there were none. Recently I found a Hyundai best practice document that states the KSDS update is no longer a prerequisite. I had my car towed once again to the dealership, where it was again denied for not having the update done prior to engine failure. Hyundai customer service says they can-??t help change the denial even though the company is at fault for producing a bad product.

The contact's husband owns a 2016 Hyundai Santa Fe. The contact stated that while driving at various speeds, the vehicle failed to accelerate upon depression of the accelerator pedal. The check engine warning light appeared on the instrument panel during the failure. Despite the vehicle operating in LIMP Mode, the vehicle was taken to an independent mechanic where an oil change was performed. The mechanic warned after the service was performed that there may be an ongoing failure with the engine. Several days later, the contact stated that while in stop and go traffic, the vehicle stalled with the check engine warning light illuminated. Due to the failure, the vehicle was towed to an independent mechanic where a diagnostic test was performed; and the contact was informed that the failure might be related to the cam shaft. The contact had the vehicle towed to a dealer and informed that the failure was probably related to the high-pressure fuel pump. The high-pressure fuel pump was replaced; however, the failure persisted. The contact was then informed by the dealer that the engine needed to be replaced. The manufacturer was not notified of the failure. The vehicle remained with the dealer unrepaired. The failure mileage was approximately 200,000.

Car started to present problems at around 100k miles when it would start to hard shift any time it shifted in to 2nd gear. On several occasions it would fail to accelerate beyond 25 mph one of these instances happened while driving at speed on the interstate where pressing the gas pedal to the floor did not accelerate the car. Resently the engine would not turn over instead all of the display and indicator lights would flicker on and off rapidly. In all of these instances the car never through any codes with the exception of one time i May 2024 and were inconsistent enough that it was difficult to replicate issues when brought in for inspection. All of the above symptoms were alleviated by adding about a quart of oil every 1,000 miles or so. Again when asking about these issues the repair shops could never give a reason for why it was going through so much oil.

Four weeks ago, I noticed my 2016 Santa Fe was not blowing any heated air into the cabin. A/C would come out fine, but room temperature air at best even when thermostat set to max. I took it in for diagnosis at a local mechanic who informed me that coolant was leaking out of the engine block and into the exhaust. I took the car to the dealership who informed me that the engline block itself had somehow gotten a tear in its side. No telling how the damage occurred, yet the warranty company (Costguard) in acquisition of my powertrain policy rejected the claim because (without ever personally inspecting the vehicle) there "was no discrepency as to how the damage occurred." Every mechanic at the dealership who has seen my car disputes their answer. I have been up to date on all maintenance on my vehicle throughout my ownership and have receipts, but cannot add them as they are all in my glovebox and the car is still at the shop. While I find it personally ridiculous that a warranty company would deny this, it is important for me as well to add to the list of engine complaints about this car. Likely the damage to the engine block has also been the cause of reduced mileage I have experienced lately.

What component or system failed or malfunctioned, and is it available for inspection upon request" Engine failure due to oil consumption How was your safety or the safety of others put at risk? Car attempted to die on a highway, this could have been dangerous had I been in the outside 'fast' lane when it struggled. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the dealer has confirmed the engine needs a full replacement Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, only the dealers service center has inspected the vehicle Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" Yes. There was a blink engine light shortly before the car engine died. However, there was no indication the oil was low in the engine. The oil light did not come on.

I purchased this vehicle less than a year ago from a dealership, used. I noticed the oil consumption after the first few months was unreasonably high. I have to keep a large jug of oil in my car and add the oil at least every two weeks or so depending on the miles I drive. I noticed other Hyundai owners complain of the same issue and some being resolved. However, my VIN is showing no open recalls at the moment.

Engine has serious recall that I was not made aware of during purchase. My car has been burning oil and the engine has been on. I've taken out to several local mechanics who said "these model Hyundai's burn oil once they are over 100,000 miles" and that I would just need more frequent oil changes. I was also told the engine light was either an old code being thrown, or the pump valve, but nothing to worry about because it really only effects gas milage. My engine went out and I had to get it towed to another mechanic, who upon seeing the car, knew it had an engine recall and could hear a distinctive knock in the engine due to a failing rod bearing. Upon Hyundai's request, we towed it to a dealership to have them inspect it. They agree it's the engine that's bad, but since a "knock sensor" was never installed by the previous owner, they say they are not liable to cover the repair, and that since the recall is "public knowledge", it was my responsibility to find out. If you go onto the NHTSA.gov website, and type in my VIN number, the information says "0 unrepaired recalls", therefore making it impossible for me to have known about the recall without Hyundai letting me know, which they didn't.

- Lenoir, NC, USA

Driving on a slight upgrade, lost power and smoke started to come out of the vents and from under the hood. Had no brakes and by the time we were able to drift to a stop, the engine compartment was on fire. There was no warning lights. Witnesses saw fire under the car while we were coming to a stop. The car and all contents were totally consumed. Following some research on NHTSA vin decoder we found that this car has the same engine (GDI THETA II) that has been involved in many fires and is involved in class action suits. Even though this car has the same engine, it was never recalled. That may indicate that there are other cars out there that may have the same problem but have not been informed.

Engine shuts off and slows down while driving.

- Burton, MI, USA

We were driving through our neighborhood at about 25 mph and we heard a slight knocking noise and then the engine shut off, no warnings or lights, just engine failure. The electronics worked, but car wouldn-??t start. Had it towed to a local mechanic where he said the engine is seized. We were thankful this happened at a low speed in a safe place, can-??t imagine how awful it would have been if we-??d been going 75 mph down the 4 lane interstate. Of note, we have always kept the vehicle current on oil changes/maintenance. Prior to this, the car drove great! Never had any issues that would point to impending trouble.

Was driving on a 5 hour car ride at 5pm on August 16th and was going up a hill, the vehicle quickly lost all power and the engine light lit. I was able to pull the car to the side of the road with the momentum that the car already had, but was not able to get the car to a safe space (its about 6 inches from an exit ramp lane), as the car would not drive. Once I got the car to the side of the road, I checked the engine and did not see any excessive heating or anything out of the ordinary. I tried to restart the car and the check engine light is lit and the battery system for the car turns on but the car will not start or try to turn over the engine. The car is currently sitting on the side of the road. My wife and my dog were in the car and we had to quickly move to a safer place away from the 70 MPH traffic. Calling a tow truck tomorrow to take it to a dealership. It was a little scary that the engine power cut out like that without giving an engine light notice in advance or giving time for me to navigate to a more safe space to park it.

Vehicle was driven on a highway approximately 45-50 mph when a loud knocking sound occured. The vehicle began to shake erratically and a bunch of lights displayed. I pulled over at a safety point and turned the vehicle off to inspect it. A large amount of smoke poured from under the hood. The vehicle sat for about 45 minutes to cool down before I attempted to start it again. The engine continued to make a loud knocking sound and kept stalling. At the given time of engine failure, I was driving on a fairly busy highway with my two toddlers where we were forced in a dangerous situation to be struck by a vehicle. Hours later, I went back to start the vehicle where I was able to get it started and drive approximately 15 mph to a safer area for the vehicle to be parked. The vehicle has been at the Hyundai Bowser Chippewa location in Beaver Falls, PA. I was denied for any assistance through Hyundai and the BBB-Hyundai due to 3 open recalls, mainly the engine knock system not being updated. All issues and diagnostics were conducted at the dealership where the vehicle is being stored. No police report has been filed, nor was an insurance claim conducted. No lights or warnings came about until the engine started to noticably fail. I didn't receive any notifications from Hyundai regarding recalls, and nothing is displayed on the NHTSA site.

On July 3, 2024 my husband was driving our 2016 Santa Fe with a v6 engine on a highway. He was coasting down a hill going approximately 65mph when he heard a loud bang and saw something shoot off to the left of the vehicle. When he tried to brake, he realized the car had shut off and he did not have automatic steering or breaks. He managed to get the car safely pulled off the highway by using all his weight to stand on the brakes and turn the car. The car did not start up again. When we got the car towed home, we were looked under the hood and found that the engine had shot a rod. We found pieces of the engine/rod along the bottom of the engine bay. We called local mechanics as well as Hyundai service center and got quotes for repair ranging from $9-20k. The car was purchased in July of 2023, the engine had 97k miles on it, with 8k miles being put on from July 2023-July 2024. The vehicle passed PA state inspection on June 2, 2024 by the dealership-??s service center.

- Butler, PA, USA

The vehicle began making a knocking sound upon starting. I contacted the local dealership for a service appointment and learned that they were out a couple of months on their appointment schedule. A day or two later, my vehicle shut off while driving, I was fortunate to have enough momentum to pull of the road safely. Upon having it towed to a local mechanic, I learned that the engine seized and needed to be replaced. I contacted Hyundai and they have scheduled me for an appointment next week. Keeping my fingers crossed they will do right by me since I have always had the vehicle serviced at their Hyundai dealership. The car has approximately 118,300 miles on it.

Car started making noise after the check engine light came on. Check engine light was on for just a few days then by the third/fourth day the car starting making noise, turned off on me a few times then just died. We replaced a few sensors and the battery and starter. Two mechanics have told me the engine is locked and needs to be replaced.

Was driving on the highway going about 65mph when the engine just lost power. Pressing the accelerator and there was nothing happening. Had the car towed home. And then to a mechanic who told me the rod was bent. I-??ve always kept up on oil changes and maintenance. I just had an oil change less than a month prior. There were no warning signs leading up to this incident.

- Massillon, OH, USA

On May 23, 2023 Was inspected for an oil leak and was informed the oil was leaking from the drain bolt (oil pan was cracked), valve cover was leaking. Was replaced with a Pan assembly-engine oil, gasket-rocker cover (with GDI High Pressure Pump gasket), and gasket- fuel pump.. However on oil leak continued and cause massive engine failure. Turned it in 5/26/2024 Had to replace engine.

On 5/15, I was entering the highway when the vehicle refused to accelerate. I pushed the gas pedal all the way to the floor, and the vehicle did not respond. I checked to see if it had stalled, but the engine was still running. I watched the rpm meter as I pushed the accelerator, and noticed that the rpm-??s stayed at 1.5 the entire time. I pulled over to the shoulder and turned off the vehicle as I was afraid of causing an accident as I was not at highway speed at the time. I turned the vehicle back on and when it was safe, attempted to reenter the highway. The vehicle responded appropriately. The check engine light had come on 2 days prior to this (5/13) and I was in the process of trying to make an appointment to get it fixed. My husband ran the engine code (P0014 and P0024). The check engine light had turned off upon restarting the vehicle but turned back on about 3 minutes after resuming driving. I took the vehicle to a mechanic to have it looked at, and they noticed that the engine had lost 4 quarts of oil. There had been no oil leakage noted at any time. They added 3 quarts of oil to the engine and noticed that the knocking sounds remained. Their determination was that the car was pretty much totaled. There were no indicator lights on the dashboard to notify me that there was low oil at any time. The only indicator that showed was the check engine light 2 days before.

Around three weeks ago, we start listening to a knocking noise in the engine. As soon as we heard this noise, we took it to a mechanic near our home and the mechanic told us that there was an internal problem with the engine and we needed to take it to an official Hyundai dealership to solve this problem. Moreover, they told me this is a common problem in Hyundai's cars and the dealership would do it for free. When I took it to the dealership, they told me that I had to replace the chain timing, tensioners, CVV, and many other stuff needed (I'm sending the receipt attached, see "car report 2024.pdf"). It was going to take 10 hours of work. Importantly, this was not covered by the Hyundai warranty or recalls. I bought the car 3 years ago, and both the previous owner and I did the year service to the car. I'm sending all the receipts and CARFAX of the services. Best regards, [XXX].

6 months ago my rod bearing broke in my engine, and I needed a new engine. From the engine recall. With a broken rod bearing you get an oil consumption problem. Oil consumption ruing your cat converter. But they aren-??t telling anyone that. 6,000 miles after my new engine, my catalac converter broke. These cars are dangerous. They-??re not telling anyone that this is the next problem. They just put you back on the road. Not to mention bad for the environment!
