I first brought my car into a Hyundai certified service center after my car shook violently and my check engine light started flashing at me. I had to pull over on the side of a busy highway which is a safety risk on it's own. the Hyundai service center "fixed" my car and I was on my way. this was In September of 2023. on February 14th 2024 the same thing happened leaving me stranded on the side of another busy highway during rush hour traffic. I got the car towed to a dealer and they are telling me I need to replace my engine since there is a malfunction with the exact same parts that they replaced in September. In September They pretty much rebuilt my engine and now, less then 6 months later, they are telling me my engine is shot and needs to be replaced. How could $6,000 worth of engine parts fail after less than 6 month" not only is that not stable financially for anyone who owns one of these vehicles, it is a huge safety risk! even if I do replace the engine in my car, when will it go out again? 5 months? maybe 6 if I am lucky? at least the last 2 times, I was lucky enough to be in the right lane already and make it to the side of the road in time. What happens if that is not the case next time"

While driving in rush hour on interstate 75 on my way to work, my 2017 Hyundai Santa Fe completely shut off without any warning lights or indication of any problems. I had to drift without power in my vehicle to the far right shoulder over 4 lanes of traffic. I was towed to a Hyundai dealership who confirmed my engine seized due to a rod bearing issue. A rod was thrown due to engine wearing bear.

1. the emission control symbol has come on 2 or 3 times recently, mechanic says they don't show a problem and owner's manual says not to drive until this problem has been resolved. I have oil leaking on driveway, had it back in 3 times for that and they don't find anything. I have had fuse for accessories replaced twice and first time I try to charge phone it blows the fuse. Had this car since 2019.

This incident involved our 2017 Sante Fe XL V6 with Lamda II engine with 61,000 miles. Up until this incident, we have had zero issues or warnings from the car of any problems. My husband was driving and slowing as he was approaching a light, while without any warning, the car stopped responding (electrical shutoff and gas would not accelerate). This was in the middle of a two-lane road with speed limits of approximately 40mph. Luckily, there were no others around him at the time of the incident. Upon taking it to an independent dealer, they diagnosed the issue with an engine knock and told us we needed a new engine. After transporting to the Hyundai dealer, they indicated it was a timing issue and needed to replace all CVVT and timing components. They did not investigate the knocking sound and admitted the repair of the CVVT could still result in the engine failing. I mention this because it is clear this engine issue is widespread and known. And yet, despite knowing this, this Hyundai dealer was willing to knowingly put me, my family, and the general public at risk for a more catastrophic engine failure in heavy traffic. Until Hyudani is forced to address this issue, this will continue to put countless lives a risk.

Catastrophic engine failure while driving - engine rod punched a hole through the engine. Up to date on oil changes, no lights on until it happened.

- Piscataway, NJ, USA

The vehicle has a very significant oil consumption issue. We are putting oil in every couple weeks but there is no sign of oil leaking out of the car. While driving the car on the highway one day, the car started to sputter and shake badly. We took the car to a mechanic and we were told the compression in #4 was shot. We just had the car inspected at the local dealership a month prior and nothing was indicated as being wrong.

- High Springs, FL, USA

Noticed a slight loss of power on a 4 hour road trip. When we stopped for gas the vehicle was shaking at lower rpm and the engine light came on at that point. I took it to a mechanic within 45mins of noticing the issue and it was scanned and a few other tests. Mechanic said cylinder 6 was misfiring, spark plug was covered in oil and compression test showed less than 20 psi. He said we were lucky to make it into town like that and we did not get stranded as there is poor service where we were. I had to get the vehicle towed approx 300km and sort out rides for my family along with a vehicle full of hockey gear and a weekends worth of clothes food. The problem has not self corrected. I will be taking it to my local mechanic to get a 2nd opinion. Currently the vehicle will continue to sit in my front yard until Hyundai wants to fix it for free.

I loved my 2017 Hyundai Santa Fe and faithfully got my oil changes. In [XXX] days started my car and heard a knocking noise as I drive home the noise got louder and louder. I took it to a Hyundai dealer on 12/21/23 and dealer said Rod bearings failed and I need a new engine and I had to pay $12K cause it-??s out of warranty. The engine is only 6 years old and should not fail with routine maintenance. Hyundai will do nothing. Hyundai had a recall on engines built 1/26/17-2/13/17 and my car was manufactured on [XXX] - just [XXX] days before and has the same exact problem as the recall but they won-??t replace my engine. [XXX] it didn-??t lock up and cause an accident while I was driving the car. There are many others with this failing Lambda 3.3 engine and we need help! [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). The contact wanted to add the engines fail with no warning lights. Hyundai doesn't have a sensor for the failing part and no low engine light.

Findings from Rick Case Hyundai Service Department in Duluth Ga: Intake sprocket came apart. Bolts sheared off causing metal to go through the engine, with sprockets rubbing on timing cover. Recommendation from Rick Case Hyundai service department to replace the engine.

On [XXX], I was driving southbound on the highway near Elizabeth City, NC when all of a sudden, my vehicle decelerated from 65 mph to 20 mph (limp mode) with no warning except for the sudden onset of a knocking noise in the engine compartment and the check engine light coming on immediately before entering limp mode. I was in the passing lane and thankfully was able to safely make it to the shoulder of the road. I had the vehicle towed to an independent engine and transmission shop where I was informed that the timing chain had caused severe damage to the engine, including metal shavings in the fluids. I had just had an oil change 3 days prior and am the second owner of the vehicle. It only has approximately 78,500 miles on it and I have only owned it for three months. I have insured that all maintenance was up to date and verified with the dealer that it had been maintained per the maintenance schedule prior to me purchasing it. The engine seems to be a constant and known problem for 2017 Hyundai Santa Fe-??s with the 3.3L engines, and it truly needs to be addressed before someone is seriously injured or, worse yet, killed from not being able to safely make it to the shoulder of a road.

Engine seized while driving down the highway. No warning, check engine, etc. indicators preceded the incident. Vehicle has <80,000 miles on the engine. I am the original owner.

My engine randomly and failed one evening that we were driving. It made an Odd sound as we were driving 35 mph down a hill and it just shut off completely. After taking it to the dealership we bought it from we were told the engine needed replaced. We still owe $14,000 on this car and it only had 71,000 miles on it. There were no indications that this was going to happen, no warning signs or signals. This vehicle was maintained regularly and very well.

I own a 2017 Hyundai Santa Fe and have noticed excessive oil consumption in between regularly, scheduled oil changes with my personal mechanic for the past 8-9 months. At NO TIME did any error or sensor codes or warning lights come on. At one point, it was down 5 qts of oil! I reached out to my local dealership for an oil consumption test, but they were booked out and I was told to watch it. The service rep indicated since I had an extended warranty, the powertrain is good for up to 100,000 miles. On Nov. 24, 2023, without any warning sensors going off, the engine suddenly went into limp mode - no acceleration from 70 mph to approx. 45 mph on Hwy. 5. We immediately exited and when we restarted the engine, the check engine light came on. We immediately called AAA to tow our car home 90 miles. Our mechanic confirmed from the error code that Master Cylinder #2 had loss of compression. The engine only had 74,400+ miles and the oil was low again, despite having it full when we left for our trip. We had a scheduled appt. with the local dealership for Dec. 18th, but were able to tow it in on Dec. 7th. Hyundai Corp had agreed to pay for the full diagnostic fee, however, when they inspected it, they too got the error code for loss of compression and that the car needed a longblock replacement. Hyundai Corp denied it on Dec. 7th. All recalls have been performed. I tried calling Corp for assistance and my case was escalated but they again denied any help due to no warranty. The dealership offered $2,500 trade-in value, however, I feel that this amount was low-balled and they claimed it would cost them $15,000 for it to be re-sellable to replace the engine and a laundry list of other items that needed replacement (i.e. battery, hoses, etc.). We immediately went to claim my vehicle from the dealership and have it parked in my driveway awaiting results of a BBB claim The vehicle is currently parked in my driveway and is inoperable. The value has decreased

Like many others, my 2017 V6 Santa Fe is afflicted with the excess oil consumption flaw, and has sustained damage beyond repair. Same as others, NO warning whatsoever, no check engine or oil light came on. After noticing a clicking/rattling noise when accelerating, took to my mechanic. Four of the six quarts of oil that was supposed to be in the engine had burned and consumed internally. At 124,000 miles so beyond warranty, and even though I contacted Hyundai they of course said no guarantee there would be any coverage or compensation, despite many others having the same issue. I'm grateful mine did not leave me stranded on the highway... Hyundai MUST BE HELD ACCOUNTABLE for such a known and widespread flaw. Why no recall??

- Elkridge, MD, USA

After 106,000 miles on a long trip home acceleration stopped working on the highway and heard a clanking noise. We had complete engine failure and were lucky enough to make it off the road safely. The engine can't be repaired or replaced and is out of warranty.

- Los Angeles, CA, USA

While driving on the highway, the engine cut out and died. It appears the engine seized. This is similar to the issues with the Santa Fe 2.4L engines, however this engine is a V6. According to a mechanic that inspected the engine, it appears that the engine had been burning engine oil, which ultimately led to the engine failure. There was no warning prior to engine failure. The engine failed while driving on the interstate, and the car coasted to a stop on the hard shoulder and would no longer start.

The rod bearings went out in the engine causing engine failure.

My Ex and I purchased a 2017 Hyundai Santa Fe Limited Ultimate 3.3L engine. We always took the vehicle to the dealership for any and all services. We paid off our loan on the vehicle mid 2022. In December of 2022, the vehicle died. No warning lights or signs of damage. Beginning of 2023 I had the vehicle towed to the dealership. I was told that the engine needed replaced. After researching, I discovered 420 of the same vehicle had been under RECALL campaign 168. I believe wholeheartedly that my VIN was missed during this recall, as the engine in my vehicle died for the exact same reason as the other 420 vehicles. This is a recall! I-??ve been in contact with Hyundai and told that because the vehicle is no longer under -??warranty-??, it will not be covered. However, Federal Law says that any vehicle with a recall is covered for 15 years after the first purchase of the vehicle. I did approve repairs because when you pay off a vehicle, you hope that the corporate office of Hyundai will honor the contract of following through with recalls. I-??m in the process of getting disability. Im having surgery on my Back Nov. 2nd. I-??ve been diagnosed with an autoimmune disorder this year and have many follow up appts and physical therapy that I have not been able to make the appts due to not having a vehicle. In April, my ex was going through some mental health issues and kicked me out. I-??ve been staying at a family members Airbnb but it-??s 1 hour away from all of my doctors. I feel that Hyundai is not honoring the Recall because they missed my VIN during their initial inspections of the defective parts. Many other complaints of Engine issues have been posted on the NTSB website along with my own. A Hyundai rep that I spoke to today suggested I contact the BBB in hopes there is something you could help me with. I feel this is a huge disruption in my life as I should be focusing on my health, however I have no means of transportation, even after paying off the car.
