The car has intermittent hard upshift from 1st to 2nd gear. It feels as if the transmission seems to slip for a moment then jolts the car, making a hard bang noise and jerking forward, and at times spinning the rear wheels. If I stop the car, turn off the engine and restart it clears the issue. It does not throw off any codes. I have taken it to the Hyundai Dealer several times and they have verified it with me while in the car but since it does not give a code or warning lights they tell me they cannot fix it. Hyundai corporate has also been made aware. This started at 77K miles and has been occurring for the last 3 years. I have brought it into hyundai over a dozen times for the concern. I have several videos of the issue

The vehicle suddenly shut down while driving and the wheels locked up. There were no warning indicators at all. The failure happened to occur on a residential street, but if at speed on a highway this likely would have resulted an an accident. Upon inspection at the dealership it was determined that a connecting rod bearing failed and the rod had created a nearly 3 inch split in the engine block.

I had just dropped my son off at the barbershop by my apartment. As I left the parking lot I proceeded to pull out into the street, as i tried to accelerate the car sputtered & lost all power. I then coasted into a nearby Wendy's. I parked & tried to crank the car to no avail. I then noticed a burning smell followed by some smoke. I had no dash lights prior to indicate any issues. I ended up calling my insurance to get help with the vehicle. Long story short the starter, coil pack & plugs along with the engine had to be replaced.2

Was going down the highway at 65 when my vehicle completely lost the accelerating component. Almost got rear ended so I pulled off. Then made it to work when it happened again. The engine light came on and gave 2 codes. Finally got it towed to the dealership where they have decided it-??s either a new timing chain or new engine due to mechanical loss. They discovered there was no oil in the car and they have also found metal shavings in my oil. Now they are telling me I need a whole new engine. I only have 135,644 miles on this car. The car was driving perfectly fine the day before and had just been to the dealer and looked over 1,500 miles before and I was told everything was perfect working condition.

On [XXX] (a Sunday, 9 pm), my 19 year old daughter was driving our 2017 Hyundai Santa Fe Limited when a solid yellow check engine light came on. No other warning lights were on. She called us, but since a solid check engine light should not indicate an emergent issue, we advised her to carefully drive the car back to school and we'd get it checked out the next day (since it was after 9 pm on a Sunday). The vehicle didn't make it that far. While driving, the car suddenly lost power and stalled. It started up again but made a terrible sound. We were able to call roadside assistance and had the vehicle towed to a nearby Hyundai dealership. The dealership tells us the car needs a new engine and that our VIN it is not covered under any of the other current engine recalls (even though this is the exact same issue as those recalls) and also said they will not repair under the 100,000 mile warranty, since we are the 2nd owners. We are awaiting a report from the dealership on exactly what happened to kill the engine, but we can infer, through the discussion with the service manage, that this is exactly the same issue happening with other versions of the Santa Fe engine -- including complete engine seizure without any accompanying warning lights or indications. This poses an imminent risk to the safety of drivers and passengers. My daughter was 20 minutes from her college dorm, late at night, and we can only be thankful she was not driving at high speed on the highway when the engine seizure occurred and also that she was not left stranded in an unpopulated stretch of highway. The vehicle is currently at Steele Hyundai (address: 24795 I-35, Kyle, TX 78640. Phone number: (512) 262-2020 ). They have quoted $13,000 for a used replacement engine. Please issue a recall on the 3.3l GDI engine. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My wife was driving down the freeway to work during morning commute when her 2017 Santa Fe just lost power, was only able to go maybe 20mph which during an early morning Bay Area commute is very dangerous... No engine light or any warning lights, this lasted for a couple miles until the next exit she pulled off still no warning indicators showing, she turned off the car for a few minutes, then turned it back on to continue to work there was still almost no power but no indicators on the dash, finally after a few minutes started driving normal again. The next day when she was on her way to work, she started getting an oil light, I drove 45min to her job checked and oil level was fine, turns out oil pressure sensor was bad. After that was replaced everything seemed normal for around 1month or so then noticed excessive oil consumption, needing to add 1qt every 1500-2000 mi, no oil leaking onto out driveway and can't see any oil leaks visually around engine. Oil consumption has gotten progressively worse, we keep it topped off every couple weeks. No we are getting check engine light and tapping sound on passenger side of engine. Codes P0346, P0021 and P0087, power is fine but tapping sounds bad and worried of failure while driving.

Oil compsumption noted and leakage noted by mechanic. Informed me could cause a fire in engine compartment. Unsafe to drive. I rented a car.. Engine burning oil, high oil consumption, oil leak. Reported to Hyundai. Took vehicle to Kerry Hyundai, Alexandria, Ky. Was informed that Hyundai won-??t take care of it. Filed a complaint. Mediation through The Better Business Burrau. Claim was denied. I was not driving the car for a couple weeks. I am guardian of 2 school age children transporting to and from school and activities and was concerned for our safety. Took vehicle to Superior Hyundai, Cincinnati, Ohio for an oil change and reported an oil leak. Was informed there was no oil leak. Had oil changes at Valvoline, Newport, Ky, No report of oil leak. Walmart, Ft Wright, Ky pointed out leak from oil pan. Replaced oil pan. Check engine light came on. Took vehicle to Konen-??s Pittstop, Bellevue, Ky who repaired oil leak. Continued oil check for consumption. Again check engine light illumination. Recently Replaced spark plugs & wires, catalytic converter. Engine running rough. Valves going bad. If car stalls on highway an accident could occur. Hyundai has a recall in the same year and make but not for those manufactured in the state of Alabama. The dealership inspection was about a year ago at Kerry Hyundai, Alexandria, Ky. They only recommended oil changes. I cannot afford the additional engine repairs. Hyundai has prior knowledge of the engine defect and refuses a recall thereby endangering peoples lives.

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"

I was driving down the road to get dog food when all the electrical went black on the car and it started down shifting, it quickly came back on It put my safety and others around me at risk as I was on [XXX] in Eustis a high traffic area in the middle lane and close to nowhere to get on the side. The next day it had started knocking - the rod bearings, I turned it off quickly and that was the last time I had turned it on. I had taken it to the shop and they said the engine will have to be replaced. We have had this (2nd owner) car a little over a year. Owe 24k on it and they are telling me it will be 14k to replace the engine. Towed it to our local Hyundai where they are saying the same and there is no recall on it.

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.

On 11/6/ 2023, while drive on the turnpike my check engine light went on and vehicle went in limp mode. I was scared and felt unsafe as I did not know what was happening. Got vehicle to dealer and P1326 was the code. Vehicle needs new engine. BCT test failed. Hyundai not helpful even when documentation provided.

- Holyoke, MA, USA

Driving down rd at 35 mph felt a sudden jolt and loud noise, car lost power and all lights came on. Coasted to a safe driveway and shut it down. Tried to re- start and it was a loud racket so immediately turned back off. Crazy thing is the oil was just changed, no leaks in garage or warning lights. Now I-??m stuck trying to replace an engine that should-??ve lasted more than 5 years!

Morning of October 16th, wife said engine "clicked" at start and then stopped at idle. I checked oil as it had been changed week prior and all levels were normal, then performed diagnostic with Carista tool and app, no codes. That evening while on the way to my 4 year olds practice, the car stopped in a lane of travel on a main cross town thoroughfare in Charlotte NC in rush hour, my wife, 4 year old, and 1 year old in the car. No light or indicators AT ALL ever came on NOTHING, no check engine light, nothing. Had it towed to local shop and he said this is the 10th or 11th Santa Fe we have seen with the V6, it most likely is the motor. So he does prelim diagnostic and suspects a thrown bearing and recommended we tow to Hyundai dealership, just at 70k, how is this possible? We are second owners and our VIN does not qualify for campaign 168. Shocking to now realize this appears to be an ongoing issues with this engine

The engine of my 2017 Hyundai Santa Fe started making a loud knocking sound on 9/29/2023. I took the car to a certified mechanic who said that the engine had -??thrown a rod.-?? I researched the NHTSA website and found NHTSA Part 573 Safety Recall Report No. 17V-578 dated Sep 20, 2017. While I never received this notice, the Descriptive Information and Description Defect mirror the problem with my car exactly. The recall was for 3.3L -??Lambda-?? engines produced at the Asan Plant (Korea) between January 26, 2017 and February 13, 2017. My car was produced February 7, 2017.

My -??17 Santa Fe has been well taken care of with regular oil changes and we have kept up with the recommended maintenance. While driving on 8/17/2023 the car started to struggle to accelerate and I heard a knocking sound. Within moments there was total engine and power failure and I had to quickly get the vehicle off the road to avoid being rear ended. There were no warning lights on until the moment it was dying. The battery light, check engine light, and oil light came on, but then the vehicle had quickly lost all power immediately after. Once it was towed to Meineke and looked over by the mechanics there it was determined that it needs a new engine and that it had very, very little oil in it.

Upon approaching stop sign, the vehicle stalled and after restart, the vehicle ceased acceleration at intervals. This caused the vehicle to impede/slow traffic during journey. Again, at stop light, the vehicle stalled and -??all-?? warning lights appeared. The engine failed to restart and the vehicle was towed from traffic due to engine failure. The vehicle is a 2017 Hyundai Santa Fe Sport 2.4 with 116,000 miles. An Engine Class Settlement has been established for the model years 2010-2012 with this same issue. The vehicle will be towed to a dealership for inspection, confirmation and repair. I felt the need to make an incident report thinking maybe other reports have been filed, also, and the manufacturer reusing to admit to problem issues.

- Saint Louis, MO, USA

The car is 2017 Hyundai Santa Fe with a defective crankshaft. The car is leaking oil. I called Hyundai and they noted that although they have recall 168 the VIN for my car doesn't match a recall that is on their website. I spoke to a Hyundai case manager today who said that even though my car has the defective crankshaft they will not repair the vehicle because it beyond 100,000 and the recall is expired. I am seeking help from the NHTSA as my car should be covered under this recall. I took it to an independent shop that noted that my car should be covered. I have photo and documents to prove that my car should be covered under this recall. My VIN just doesn't match their records and they are denying my claim.

- Mount Prospect , IL, USA

Not really an incident but my car has the same issue as the class action lawsuit from Hyundai for issues with the connector rods going out. I can-??t get it fixed because of this issue. Hyundai says they can-??t do anything about it and sent me your info! Can someone please help me" I still owe $23,000 on this car! Is there a way to add the recall to my car" It is an almost $14,000 repair! It started knocking out of nowhere and isn-??t drivable because of the issue.
