2017 Santa Fe with 85k miles suddenly has engine failure. Come to find out this is a common problem in these vehicles specifically. Was stranded on the side of the freeway for over four hours. Told me there was practically nothing they could do for it. Never had an issue before and got regular oil changes before the 3k mile mark. Told me the engine threw a rod. Never had a problem like this with any other car, even ones much older (over 7 years over).

I took my Hyundai Santa Fe sport to Central Valley Hyundai in Modesto, CA on 10/31/2024 to have a diagnosis done to the car since the car turned off on me while I was driving and after a week being at the dealership this was their response. Hello [XXX], sorry for the late reply! We are short handed today, and busy! Anyways, My technician had the chance to take a look at your vehicle. Your vehicle is going to need an engine due to it not passing the bearing clearance test. I submitted paperwork to Hyundai and I am currently waiting to hear back from them in regards to a decision. I will let you know as soon as I hear something. after another week went by this is what Hyundai had to say. I just checked, and they declined the coverage of your engine, this was their response: The vehicle is not eligible for extended warranty TXXI. Per the terms of the extended warranty, the campaign 953 software must have been installed on the vehicle prior to bearing malfunction. Our records indicate campaign 953 was not completed on this vehicle. For further clarification, the terms of the extended warranty and related settlement. Notice may be reviewed here. [XXX] . No goodwill assistance is being offered at this time I was never made aware of a recall that needed to be done to the engine. I never received a letter in the mail and also I spoke to Hyundai customer service and they said that I never received the notice due to being sent to the original owner which was a car rental business.

While driving my 2017 Hyundai Santa Fe Sport, I heard a knocking sound coming from the engine. Shortly afterward, the vehicle began moving jerkingly forward, and the oil, engine, and battery warning lights illuminated on the dashboard. The vehicle then shut off completely in the middle of a busy street. I attempted to restart it, but while the engine made a starting sound, it immediately shut back down. The electrical system remained functional (lights and radio), but the vehicle would not restart. Due to the failure, I had to exit the vehicle and physically push it to the side of the road in cold, rainy conditions with reduced visibility, creating a risk of being struck by oncoming traffic. Strangers who assisted in moving the vehicle also placed themselves at risk. A certified mechanic has since confirmed that the engine has locked up and identified this as a known issue with Hyundai engines. Prior to this incident, the only warning sign was the oil light briefly flashing while driving on an uneven road surface. At the time, I was on my way to have an oil change within the manufacturer-recommended time frame and assumed the light indicated routine maintenance was needed.

My wife and I bought a used 2017 Hyundai Santa Fe, and the car has performed admirably over the last 4 to 5 years.  Within the last month, the car started having stuttering issues and we took the car to our local shop, where we asked for a quick check and an oil change.  The local shop reported that we had a Crank Shaft Advance error code, and that the car did not have much oil in it.  We have not seen major oil loss between oil changes before, which concerned me.  Once the car was full on oil the error codes cleared and the car worked well over the next few weeks.  Oil levels seemed good during that time, but my wife took the car out to New York and back, then a trip into Boston (around 600 miles overall).  On the way back from Boston, the engine stalled and would not start.  We sent the car to be checked at a local Pep Boys, they performed a borescope and believed that the engine needed replacement. I contacted Autofair Hyundai and had the car towed there to service under Hyundai TSB 24-EM-007H. [XXX] >> The dealership mentioned that the diagnostics would cost ~200 dollars and detailed a number of error codes (low fuel flow, crankshaft advance, etc.). They then quoted a $8,000 to make the repairs and then they could check to see if the car met any warranty requirements. I opened a ticket with Hyundai and the ticket was closed. I believe this falls under Docket No. [XXX] and should be covered under Hyundai Technical Service Bulletin (23-EM-007H) [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I refilled it and then began checking my oil weekly. I add at least 1/4-1/2 quart per week between oil changes. Every time I take my car in for an oil change they have to add an extra quart and make me aware that my vehicle is burning a significant amount of oil... This is my everyday car, I use it to get back and forth to work, I transport my children in this vehicle. There is a 953 Recall and also 218 but my VIN is not included.

T3G Campaign 2017 Hyundai Santa Fe Sport AWD, 116000 miles. Purchased from a dealer in VA [XXX]. Never would have purchased if engine issues had been disclosed. The letter re:T3G campaign went out to dealers/service managers from Hyundai (of which I have a copy) is dated for October 2019. We never received any information regarding a T3G campaign. We took my car to the dealership on 12/16/24. (Valdese, NC). In 5 hours, they said they ran diagnostics & found the P0302 Misfire code. Without running further tests, they adamantly claimed there was a dead cylinder & the only fix was to replace the engine. Note: Spark plugs were replaced 2 weeks before this visit on Dec 1, 2024. They refused to listen to my concerns about the T3G campaign. Said vehicle didn't have that issue. That they couldn't run the tests because the P1326 code wasn't present (but it was in Sept). They didn't do anything about the current open recalls. They said they didn't have time. Corporate confirmed that my vehicle has had the correct service campaigns completed to qualify for the T3G campaign. I have called corporate twice-No response. We are very upset over the lack of care and solutions. We gave consent for work & nothing was done. The service manager was practically shouting that this car would leave me stranded, it wasn’t safe to drive, & that the only option to fix was to replace the engine/get rid of it. I was basically told it wasn't worth fixing. Putting a new engine in would equal than the car is worth at trade in value. No one can give me a guarantee that a new engine (even brand new from the factory) would not have the same problem that is happening now. Make this right by immediately authorizing an engine replacement for my vehicle to include a loaner vehicle & tow charge cover. I am aware of the class action lawsuit from 2021. Hyundai refuses to issue a recall for this engine issue. Please see attached letter for more information. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

In June 2024, my vehicle suddenly lost power while I was driving on the freeway, almost causing a serious accident. I managed to restart the car after being stuck on the shoulder of the freeway for several minutes. The same issue occurred the following day, prompting me to have the vehicle towed to the dealership. Hyundai Motor was contacted since the vehicle is still under warranty. The dealership informed me they would conduct an oil consumption test three times to diagnose the issue. However, they also stated that for the test to be successful, I needed to replace unrelated parts, including the brakes and transmission oil, among other items. Reluctantly, I agreed and spent $1,800 on these replacements. After completing the first oil consumption test, I returned for the second test. However, the dealership informed me that no further tests were necessary and returned the car to me without addressing the underlying issue. I emailed the case manager assigned by Hyundai to report this, but I never received a response. A few months later, the car failed to start. I contacted Hyundai again, and they dispatched a tow truck. The tow truck driver managed to start the car. A few days later, the issue recurred, and the roadside assistance tow driver suggested it might be the battery. Out of frustration, I paid $300 to replace the battery. Despite this, the car continued to make unusual noises at startup, a problem I had repeatedly mentioned to the dealership and in my communications with Hyundai. The situation reached a critical point today when my wife was driving the vehicle on the freeway with our five children inside. While traveling at 60 miles per hour, the car suddenly lost power again, putting their lives in danger. This is the third time this hazardous issue has occurred, and I fear for the safety of my family.

DP24001 · 3.3L Engine Loss Of Motive Power (lomp)

Opened Feb 8, 2024 · Closed May 16, 2024

Status: closed (inferred from source dates) · Engine

The Office of Defects Investigation (ODI) received a petition on February 2, 2024, requesting a defect investigation into an alleged defect of the "engine" on the following vehicle model: 2017 Hyundai Santa Fe vehicles equipped with the 3.3L V-Shaped GDI Lambda-II engines. The petition cites allegations of a loss of motive power, often resulting in an engine seizure. The stall is preceded by a knocking sound, decreased performance and no warning lights. An analysis of the subject vehicle population was undertaken using complaints submitted to ODI along with manufacturer data.  It was determined that the frequency of events is low for the subject population, while those that specifically report a loss of motive power event have a high mileage at the time of incident.  The 2017 Santa Fe is equipped with a service interval reminder for the consumer that must be set by the consumer themselves or at a dealership.  A Technical Service Bulletin (19-EM-002H) instructs the dealership to set the maintenance reminder at the completion of routine maintenance service or anytime a repair is performed that requires new engine oil.  This maintenance reminder will help reinforce the need for proper oil maintenance intervals.  Additionally, the Santa Fe vehicles with 3.3L V-shaped Lambda-II engines will be added to Hyundai’s existing Technical Service Bulletin (23-EM-007H) related to combustion chamber cleaning.  These actions will help limit negative consumer incidents related to loss of motive power.  Lastly, Hyundai has extended the limited engine warranty for MY 2013-2019 Santa Fe vehicles equipped with 3.3L V-shaped Lambda-II engines included in the Petition.  The updated coverage is 15 years, or 150,000 miles and details are contained in Technical Service Bulletin 24-EM-003H. In view of the service interval reminder, combustion chamber cleaning, and extended warranty actions being taken by Hyundai, ODI is denying this Defect Petition.  The agency reserves the right to take additional action if warranted by future circumstances.  To review the report cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

DP22003 · Loss Of Motive Power

Opened Sep 12, 2022 · Closed Dec 12, 2023

Status: closed (inferred from source dates) · Engine

The National Highway Traffic Safety Administration (NHTSA) received a letter dated July 13, 2022, petitioning the Agency to initiate a safety defect investigation into loss of motive power allegations attributed to oil drain pan assembly failures on certain Hyundai Motor America, Inc. and Kia America, Inc. vehicles spanning Model Years (MY) 2005-2021. The Petitioners cited examples of complaints indicating that the subject vehicles were experiencing rapid loss of engine oil due to oil drain plug back outs, resulting in loss of motive power and/or catastrophic engine damage. Additional complaints were provided which alleged that the oil drain pans lack sufficient structural integrity and are susceptible to cracking. The petition itself can be reviewed at NHTSA.gov under ODI number 11481745. On September 12, 2022, the Office of Defects Investigation (ODI) opened Defect Petition (DP22-003) to evaluate the Petitioners’ request. The Petitioners have provided additional complaints within four supplemental letters dated January 31, 2023, March 21, 2023, May 23, 2023, and August 4, 2023. ODI’s evaluation included the review and analysis of the complaints and supporting information submitted by the Petitioners, as well as additional complaints submitted directly to NHTSA which referenced either the oil drain plug or a crack in the oil pan. After reviewing the available data, ODI has not identified evidence that would support opening a defect investigation into the oil drain pan assemblies of the subject vehicles. Based on a review of the available information, a loss of motive power resulting from an oil drain plug back out has not occurred between the initial sale of a vehicle and the completion of its first oil change. If during an oil change service, a technician fails to remove the existing drain plug gasket before installing a new gasket, it is likely that a proper seal between the drain plug and the oil pan will not be made. An improper seal between the drain plug and oil pan could lead to the backing out on the drain plug, resulting in the sudden loss of oil while driving. Additionally, the provided examples of oil pan cracks were localized to the immediate vicinity of the oil drain plug and/or appeared to be the result of direct-contact with a tool during servicing.  There is no information to support that a vehicle-based defect exists relating to the oil pan assembly, and instead the documented incidents are related to the failure to follow the proper maintenance procedures during oil change service. In October 2023, Hyundai published a Technical Service Bulletin (TSB) that provided detailed instructions for oil change service on its gasoline powered vehicles, specifically highlighting the need to remove and replace the existing drain plug gasket prior to reinstalling the drain plug. After a thorough review of the material submitted by the petitioner, the information already in NHTSA's possession, and the potential risks to motor vehicle safety implicated by the petitioners' allegations, NHTSA does not believe that a formal investigation is warranted. Therefore, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA’s reasons for denial of the petition will be published. The reference numbers for the complaints to NHTSA cited by the petitioner can be found in the petition submission documents in the public file for DP22-003. To review those complaints and the additional complaints ODI added to its evaluation which are cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.
