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.

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.

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.

The engine in my 2017 Santa Fe failed without notice. Upon starting the vehicle on 12/12/23 it would not run and upon checking had burned through oil leaving none in engine. This resulted is burned out spark plugs and leaving the car no longer able to drive. I took vehicle to dealership where spark plugs were replaced and engine failed again on test drive with technician. Hyundai contacted multiple times and refused to asssit with repairs despite multiple engine failures.

Hyundai Is aware of the connecting rod bearings inside the engine may wear prematurely, which can result in engine damage. However, when I contacted Hyundai about having this issue with my 2017 Santa Fe, they said my vehicle year does not qualify for the extended recall (10 years/ 120,000 miles) which they have on other vehicles years that are experience. My vehicle currently has 92525 miles. My complaint is I believe Hyundai should cover my 2017 vehicle, knowing that they have this issue with their engine. Any enforcement action or advice that NHTSA can provide would be appreciated. Sincerely, [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The motor locked up with no warning and we lost all vehicle power and left us stranded. All maintenance and oil changes have been kept up with regularly. I have been reading up and Hyundai did a voluntary recall for only a few motors that were manufactured over about a 3-week period that were having this same issue. Apparently, our vehicle was not covered under that recall even though it is having the same problem. We had it towed to a dealership and they said that this is a known problem and they see this very often. We spoke to Hyundai and they told us that it was not a known problem and they were not going to warranty it because we were the second owners. Upon conducting some additional research, we found that this issue is known to occur in these vehicles. The internal bearings wear out between 80 and 120 thousand miles, resulting in the motor locking up without any warning signs, such as a check engine light. Our vehicle had only reached 92,000 miles. We had the vehicle towed to our mechanic and he opened the motor to confirm that the bearings did go out prematurely and caused this issue. This is a huge safety concern. If we were on a highway when this happened, it would have been catastrophic and deadly especially when it happens without any warning. The vehicle is available for inspection if needed.

- Belton, TX, USA

Engine failed at 62k miles without any warnings lights or indication of an problem. The engine knocked and seized, creating incredibly unsafe driving conditions with ZERO indications from the car other than hearing the engine noise. The Hyundai dealer confirmed I need a new engine due to the knock, and it is not covered by any warranty as I am not the original owner and the warranty expired last year and at 60k miles.

- Warwick , RI, USA

Engine failed due to excessive oil consumption while driving. Safety was put at risk due to poor build leading to failure while driving. It has been inspected by the manufacturer and was determined it needed to be replaced entirely. Low engine oil light came on, replaced oil, then shortly after failed while driving, after codes disappeared.

2017 Santa Fe with 115k miles had its last oil change in June. It still has another 4k before it is due again. The motor started making strange noises. I checked the oil and had to add 4 quarts! Engine started knocking bad. Left me and my family stranded 2 hours from home. I had oil issues previously before my warranty went out. Hyundai is refusing to address the oil consumption issue and replace my motor. Please help! This isn-??t right.

- Grovetown, GA, USA

My engine failed with regular oil changes at less than 120k miles with NO warning. It was 9 at night and it completely shut down on the highway. The hazards, brake lights, etc were not operable! I was almost hit by traffic three times due to not being able to turn on hazards and brake lights not working. I could not even place the car in neutral. Thankfully, the local police department was finally able to assist me but it was a frightening experience and Hyundai is doing absolutely nothing about it.
