My wife was driving down Hwy 105 west in Montgomery, Texas on a 6 lane highway when all of a sudden our 2017 Hyundai Santa Fe lost power at 65mph. She could not accelerate or maintain speed and noticed several light quickly flash and then shut off. She steered into the center median and stopped in order to try and restart the car. There was no warning to this issue and the Santa Fe could not be restated and had to be towed to Weisner Hyundai in Conroe Texas to be diagnosed. It was revealed the knock sensor that was supposed to put the vehicle in safe mode so engine damage would not occur, failed with no warning which caused excessive bearing and rod wear causing the engine failure which could have caused an wreck on the road. The Weisner Hyundai in Conroe inspected the Santa Fe and mentioned the state of the engine showed it was well maintained and no signs of sludge in the engine. There were no warning lamps on the dash or symptoms with the engine leading up to this issue. This is a major safty risk is due to the immediate loss of engine power which other cars had to quickly swerve to miss my wife as she steered to the middle median. Weisner Hyundai elected to process a PA claim with Hyundai with photos and a full report. As of today, I have do not have the full report as the service center was still in the process to filing their report.

My family was driving down the interstate at approximately 78mph when the engine light came on and the vehicle began to rumble intensely. After letting off the gas to approximately 50mph and touching the gas once more we realized the vehicle was not operable. We pulled to the side of an active interstate and awaited towing. We were in this spot for almost an hour hoping my wife and children were not struck by a vehicle. Additionally, as the vehicle broke we were concerned about being hit on the active interstate. Oil had been recently changed, maintenance was always kept up-to-date, no dash lights were on, and we had experienced no prior problems with the vehicle or engine. Vehicle has been inspected by a mechanic shop and a warranty representative, both of which stated the engine was dead. It now sits with a Hyundai dealership for further diagnostics testing.

The check engine light came on one day and then before I could take it in to be checked, about two days, the light had turned back off again so I thought it was fine. Then, I was driving 2 hours from my home and on the way back the engine started to make a terrible knocking and screeching noise. It seemed like it was going to break down. I was on a country road so I quickly turned around and made my way back to a truck stop about a mile away. I had to pay to get the car towed to my local dealership an hour away. While at the dealership, after inspection, I was told it was a Rod Bearing Failure in my engine. This absolutely put me at risk as I was driving a far distance and an hour from my home. The dealership then got my service records and gave them to my extended warranty carrier- Assurant. They agreed to cover the over $10,000 cost with just my $50 copay. The car now has a different, used motor in it. My concern now is that I have had the same problem that other Santa Fe's have had in prior years but this one doesn't have a recall. Now, I'm driving with another one of these motors with worries that I'll have the same problem as before and be responsible for the fix. I asked the dealership and Hyundai USA case manager if they would warranty this new to me, used motor AND reimburse me for the 40 days that I had to pay for a rental vehicle and was told NO.

While on a road trip, the engine light came on. A further check at a Hyundai authorized mechanic showed the engine had suffered from high oil consumption and ran low on oil. There was no obvious oil leak. As a result, I must replace the engine and I am unsure if Hyundai will cover the cost.

My 2017 Hyundai Santa Fe with approximatelh 118,000 suffered a catastrophic engine failure. According to the dealer where the car was towed, CVVT on the camshaft caused further damage to the engine. Recommended solution is engine replacement. Dealer is quoting approximately $13,000 + taxes and fees for this replacement. I have opened a case with Hyundai and contacted my insurance company regarding possible recourse. The dealer has indicated the 10 year/100,000 mile Powertrain warranty will not cover the engine replacement as the care has 118,000 miles. There were no preliminary warning signs of engine failure. Just minutes before the car starting leaking a ton of oil, the Check Engine and Oil indicator lights went on. Car has been meticulauly maintained and serviced over the years. The car is currently at the dealer, and I have no replacement transportation provided for this vehicle. While there were no injuried, I can imagine that had I not been in a position to have the car towed, the engine failure may have resulted in dangerous driving conditions.

Losing about 1QT of oil every 1k miles. The local Hyundai dealer acknowledged the issue but has no remedy. Their suggestion is to add a QT of oil at every 3k and check the level every 1k mile. I do not feel safe driving this vehicle as the engine also makes loud noises

I was driving the vehicle at highway speeds, when I attempted to pass a vehicle, the engine started making a knocking sound. I had the vehicle towed to the Hyundai dealership. When they did their initial inspection, there was no oil in the engine. The engine oil had been changed by a reputable dealer within 3,000 miles. The vehicle is well maintained and regularly maintained. No warning lights came on to indicate low oil or any other warning light to indicate any problems with the engine at all. Manufacturer has 10yr 100,000 mile warranty for first vehicle owner, but the warranty for second owner is 5 yr 60,000 mile. There are known issues with this engine and other Hyundai GDI engines. Dealership gave me a repair bill for a used engine replacement with labor of $12,650. Manufacturer says they are not responsible for the engine since it is out of warranty (although within original manufacturer warranty). The GDI engine is faulty and dangerous. A 5 year old vehicle burning 4 quarts of oil within 3,000 miles is not user error, thats manufacturer fault and they should be held accountable for it.

While driving to work on the highway. My car begin to stall and hesitated. There were no warning lights no indication that anything was wrong with my car. I-€™ve been pretty good about keeping up with the maintenance on my car. I creep into work and ask one of my mechanics to look over my car because of what happened on the highway. The mechanic checked it out and found there was no oil in the car. It was not time for my scheduled oil change. He asked if any lights came on, if there was any way the oil could have leaked out. No lights came on and I park in my garage everyday, no oil leaks. I told him this isn-€™t the first time it happened. He put some oil in my car and I told him I was scheduled for an oil change later that week. He said ok. On my way home the engine to knock and again stall. I didn-€™t take the highway home. My car shut off on me just before I made it home. I decidedly to call the dealership the next day. I parked it in the garage. The next morning I was letting my dog out and there was a strong gas/engine smell in my breezeway. I opened the garage to check to see if something was visibly wrong with my car still no leakage. I brought my car to the dealership, explain what happened. While waiting I was checking on recalls and discovered this is a serious on going problems with the 2017 Santa Fe-€™s. The dealership quoted me at $12000 to replace the engine. I-€™m a single parent where am I gonna get $12000.

Engine started using excessive oil. Monitored and refilled as needed. On Sept 15, 2021, Engine completely seized while driving. Took over a month to get appointment at local Hyundai dealership. Towed to dealership and confirmed engine needed to be replaced and possible AWD system damage (can-€™t confirm until engine is replaced). At dealer since Oct 25, 2021 (now May 2022). Hyundai refused warranty coverage as we are second owners. Dealer advised delay to repairs due to numerous similar engine failures and lack of parts.

Starting in September we have been documenting my engine burning, not leaking, oil at an alarming rate. I am currently losing 2-3 quarts of oil every 2 weeks. I have submitted a claim through Hyundai Corporate through the CDI engine recall program and they are denying my claim because "I'm out of warranty." The recall is supposed to extend the warranty for these issues but they are refusing to honor the terms of the recall. My car smells like burning oil and I've been told not to park inside my garage or near my home as the car is a fire hazard. I have attempted resolution by contacting the entire chain of command at Hyundai including Omar Rivera (Director of Quality and Service Engineering), Barry Ratzlaff (VP, Customer Satisfaction), and Jose Munoz (CEO and President).

While traveling at approximately 60mph I decelerated to make a left turn through a busy intersection (evening rush hour traffic). While decelerating, I felt the car give a "shudder" at which point I looked to the dash to see the check engine light blinking, then the battery light illuminated. At this point, while passing through the intersection turning left, the engine shut off, as well as the power steering. The car coasted through the intersection and came to a stop barely out of the crossing lane. It would not restart and I was forced to push the car with my family inside to a safer position. Prior to this event there had been no drivability issues, no other times that warning lights had come on. The only issue of note that I have had for this vehicle is a seemingly excessive amount of engine oil being consumed. The car is at a dealership now and I am told that the engine needs to be replaced, with no explanation for the failure.

The contact owns a 2017 Hyundai Santa Fe. The vehicle had previously been serviced under Manufacturer Service Campaign Number: 961 (Auxiliary Canister Kit Installation) however, the failure occurred after the repair. The contact stated that while her son was driving 65 MPH, the vehicle lost motive power. The vehicle was towed to the dealer where it was diagnosed that built-up oil caused the engine to fail. The dealer informed the contact that the engine needed to be replaced. The vehicle was not repaired and was towed back to the contact's residence. Prior to the failure, the vehicle stalled and inadvertently accelerated or decelerated while driving. The vehicle was previously taken to the dealer, but the dealer could not duplicate the failure. The manufacturer was made aware of the failure. The failure mileage was 96,255.

The engine is consuming oil. After 500 miles since my last oil change the oil DOES NOT show up on the oil stick. The engine warning light came on and Oil leak from engine, I have taken the vehicle to the dealership and they thought it was an oil cap plug not put in correctly. But oil leak still happen and the engine warning light keeps turn on. Every day i have to check oil level to make sure it not go below the minimum and I keep on adding oil. The dealership can't give me answers as to the problem. I have had the vehicle for a year with no issues until 2 months ago when this started.

My car was experiencing excessive engine motor oil consumption that progressively became extreme. Based on internet information, others owners were having similar oil consumption issues. The cars check engine light came on and the engine became very erratic around a sharp curve in Vermont. Struggled to get the car to the side of the road prior to the engine completely stalling. Unable to get the vehicle restarted. Luckily it was still daylight and that it failed in an area where I still had cell phone service. A local garage towed the car and and determined that there was no compression in one cylinder. They contacted Lia Hyundai in Albany NY and the service representative informed them that the engine would be covered but that the would have to inspect the car. Spent over $300 have the car towed to the Hyundai dealer. After inspection, we were informed that there was a burnt valve and that the valve assembly had to be rebuilt. They told us this repair would not be covered under the recent class action settlement which covers the small block assembly if the Knock Sensor Detection System Software was installed (Service Campaign 953). The software was installed previously. The total estimated cost for the valve assembly repairs are over $4,600. Based on the recent inflated costs of vehicles we decided to proceed with the repairs. Spent hours contacting Hyundai Corporate directly on several occasions to rectify the matter to no avail. We were told that they were going to contact the local dealer and get back to us. We never received a returned call. Lia Hyundai did provide us with a loaner vehicle and we are currently waiting for the repairs to be completed. We also asked them for an engine compression test once the repairs are complete and for the return of all damaged components. We will verify the compression results at an independent service center and also perform an oil consumption test. We have approximately 100,300 miles on the car prior to the failure.

When driving the vehicle the check engine, battery and oil light came on when about 30 feet from a green light. Started to turn into a parking lot about two seconds later and the car stalled. Had no power or steering. Was able to stop with the break, but if had been going faster on on the main road may have crashed, with no throttle or steering control. Was able to stop the car as soon as entered the parking lot. Put vehicle in park, but it started rolling back into traffic once took the foot of the brake. Had to wait in vehicle with the brake until tow truck arrived. The vehicle was towed to a dealership and and it was determined that engine had excessive bearing wear. I was told by the dealership Hyundai that based on miles that Hyundai was not going to assist with any financial support to fix the vehicle. I called Hyundai 1(800) 633-5151 and spoke with Lindsey (supervisor) who said that she would not look up recalls from the NHTSA and that my specific vin number was not identified in any current recall for that issue. I asked her to look up to see how many vehicles were affected with the safe issue year and engine size safety recall 17V578000 from the NHTSA. She said that if not in her computer linked to a specific vehicle she would not help and then hung up. We feel blessed could have been a lot worse at high speeds. The main issue is the Hyundai representative showed no concern for the safety issue once I informed them that there may be more vehicles with a similar issue to the current recall. It appears the issue is a lot larger than the initial number of vehicles recalled and will probably lead to severe injury or death if not looked into. I am hopeful they report this issue themselves, but know that they are probably more concerned about profits than consumer safety.

On January 11, 2021 I was on my way to work. I work for Kia. My car stalled out and my engine light began blinking perfusly. I made an illegal turn to get to my job where I was told to pull into service where it was diagnosed with a knock sensor code. It was towed to south Towne Hyundai of Newnan where it still is and has yet to be diagnosed. I have been getting lies saying I was next over 3 weeks. I have lost a job, exhausted all of my funds on rentals and my calls are being ignored. I filed a claim for reimbursement but at this time. I no longer want to deal with Hyundai. I would just like them to buy the vehicle back from my finance company as I completely am utterly disgusted by the policies, practice, and procedure that they refuse to honor. The case workers give false information but when you go read the website they have not adhered to anything they offer.

The Oil has been burning black for years, the oil has been burning up in between scheduled oil changes, there has been a knocking sound for years, we have advised the Hyundai dealerships and they always said it was the fuel pump or gas cap or spark plugs, these were the only items they advised they fixed and the problem persisted. Independent repair shops advised it was either the seal of the piston rings or engine issue. Hyundai dealers refused to advise if it was an issue with the engine, they also refused to perform a compression test unless it was first authorized by Hyundai corp. The engine finally died and now the car will not run, an independent shop advised there was no compression on Cylinder 2. We opened a case 18967436 with Hyundai Motor Corp since Nov 11, 2021 and to date nothing has been done.
