HAD THIS SANTA FE FOR A LITTLE OVER A YEAR. I HAVE NOTICED SEVERAL INSTANCES OF NOT BEING ABLE TO ACCELERATE, OR GAIN SPEED, ESPECIALLY WHEN TURNING OR STARTING FROM A STOPPED POSITION, IT HESITATES TO START TO THE POINT OF ALMOST BEING HIT SEVERAL TIMES. I HAVE TAKEN IT TO DEALER MANY TIMES, AND THEY KEEP TELLING ME ITS THE WAY I AM DRIVING IT THAT THE ENGINE IS LIKE A STANDARD VEHICLE, BUT THAT DOESNT SEEM SAFE TO ME IF I AM TRYING TO START DRIVING AND IT WONT GO. WHEN IT DOES FINALLY DECIDE TO GO, IT TAKES OFF WAY TOO FAST AND IS LIKE, IT FINALLY DECIDES TO SHIFT INTO GEAR. ALSO WHILE IN PARK, ENGINE REVS TO 2500RPM FOR NO REASON OR IDOLS AT THAT RPM. IT FEELS LIKE THE ENGINE IS PULLING THE CAR FORWARD EVEN WHEN IT IS IN PARK I HAVE BEEN GIVEN THE RUN AROUND SO MANY TIMES, I AM TIRED OF IT. I'M NOT HAPPY TO SEE OTHERS HAVE THIS ISSUE, BUT I AM ALSO GLAD THAT OTHERS ARE EXPERIENCING THE SAME PROBLEMS.

2017 HYUNDAI SANTE FE SPORT AWD - PURCHASED IN OCT 2017. CURRENTLY HAVE 7525 MILES ON VEHICLE. I NOTICED ACCELERATION HESITATION IMMEDIATELY AFTER MAKING IN CITY TURNS (FROM BOTH STATIONARY AND IN MOTION TURNS) AS WELL AS WHEN GETTING ON HIGHWAY (IN MOTION). I AM RETIRED AND DO NOT DRIVE SANTE FE VERY OFTEN. THE PROBLEMS WITH ACCELERATION AFTER MAKING STATIONARY AND IN MOTION TURNS AND GETTING ON HIGHWAY HAS ALWAYS BEEN PRESENT SINCE DAY OF PURCHASE. I HAVE NOTICED THE PROBLEM HAS BECOME MORE PREVALENT AFTER TAKING A 1000 MILE ROAD TRIP THIS PAST AUGUST. THE ACCELERATION/ HESITATION AFTER TURNING IS MORE NOTICEABLE AND IS BECOMING CONCERNING BECAUSE I HAVE TO PRESS PETAL TO FLOOR TO GET THE SANTE FE TO ACCELERATE PROPERLY TO GET OUT OF WAY OF ON COMING TRAFFIC. HESITATIONS/ACCELERATION PROBLEMS OCCURS AFTER TURNING AND WHEN ENTERING A FREEWAY. VERY POOR ENGINE PERFORMANCE GIVEN THE VEHICLE COST OF $35,000. I OWNED A 2011 HYUNDAI SONTA FOR 6 YEARS AND HAD THE SAME 2.4L ENGINE AND I NEVER EXPERIENCED ANY ENGINE HESITATION LIKE I AM NOW WITH THE 2017 HYUNDAI SANTE FE SPORT AWD.

SMART CRUISE CONTROL FAILS TO BRAKE INTERMITTENTLY. IT IS DESIGNED TO MATCH SPEED WITH THE CAR IN FRONT OF IT. IT USUALLY WORKS FINE, UNLESS ANOTHER VEHICLE CUTS IN FRONT, EVEN IF THERE IS ENOUGH TIME TO BRAKE. I HAVE TO SLAM ON THE BRAKES MANUALLY TO AVOID AN ACCIDENT. THIS HAS HAPPENED ON MULTIPLE OCCASIONS. I NOW FEAR USING THE CRUISE CONTROL AT ALL, AS IT DOES NOT PERFORM CORRECTLY 100% OF THE TIME. THE DEALER SAID THEY COULD FIND NOTHING WRONG, BUT THIS IS A VERY REAL ISSUE THAT PUTS MY FAMILY AT RISK. THEY HAVE NOW CALLED IN A MASTER TECH FROM HYUNDAI TO LOOK AT IT, BUT I WANTED TO DOCUMENT THIS ISSUE. I NOTICED IT FIRST WITHIN TWO WEEKS OF PURCHASE. HYUNDAI SUPPORT CLOSED MY CASE SEVERAL TIMES WITHOUT ACTION. I BOUGHT IT 5 MONTHS AGO. CURRENT MILEAGE IS 3462, SO IT IS WELL WITHIN WARRANTY.
WHEN THE CAR START AT THE TRAFFIC LIGHTS AND SLOWLY ACCELERATES WHILE DRIVING, THERE IS A SOUND IN THE CAR. I HEAD A SOUND FROM THE ENGINE OR MUFFLER.

3DP24001 · 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.
