I HAVE HAD ON AT LEAST A HALF DOZEN TIMES WHERE THE VEHICLE WILL NOT ACCELERATE AFTER STOPPING, AND THEN ATTEMPTING TO ACCELERATE. FOR EXAMPLE: LEAVING A PARKING LOT GOING ONTO A ROADWAY ATTEMPTING TO ACCELERATE QUICKLY TO GET UP TO THE SPEED LIMIT. ATTEMPTING TO TURN LEFT AT A FLASHING RED LEFT TURN LANE TRAFFIC LIGHT. THE VEHICLE WILL ROLL ABOUT 10-20', BUT WILL NOT ACCELERATE, LIKE THE TRANSMISSION IS NOT ENGAGING. SOMETIMES THE ENGINE WILL REV TO 4000-5000RPMS. I WILL QUICKLY LET OFF OF THE THROTTLE, THEN IT WILL TAKE OFF. THE ENGINE DOES NOT REV EVERY TIME. THE DEALERSHIP REPLACED A MODULE ON THE TRANSMISSION APPROXIMATELY ONE YEAR AGO, BUT IT DID NOT HELP. THEY HAD IT FOR ONE DAY IN JULY 2020, ATTEMPTING TO REPLICATE THE PROBLEM, BUT TO NO AVAIL. THE MOST RECENT INCIDENT WITH THE VEHICLE WHERE THIS FAILURE TO ACCELERATE OCCURRED WAS 12/26/2020, WHERE UPON LEAVING A SERVICE STATION ONTO A FOUR LANE ROAD, IT ONCE AGAIN ROLLED TO 10-15 MPH, BUT WOULD NOT GO WHILE THE ENGINE RPMS WENT TO 4000. AS TRAFFIC WAS RAPIDLY APPROACHING I KEPT MY FOOT ON THE THROTTLE, AND IT FINALLY STARTED PICKING UP SPEED. THIS IS GETTING TO BE A DANGEROUS VEHICLE TO DRIVE.

MY QUESTION IS , THE RECALL SAYS THAT HYUNDAI MOTOR COMPANY RECALLED 420 2017 HYUNDAI SANTA FE'S THAT WERE PRODUCED BETWEEN JANUARY 26 2017 AND FEBRUARY 13 2017. MY SANTA FE WAS ACTUALLY PRODUCED ON JANUARY 14 2017, WHICH IS ONLY 12 DAYS PRIOR TO THE START OF THE OFFICIAL RECALL PRODUCTION DATE OF JANUARY 26. HOW DOES HYUNDAI MOTOR COMPANY KNOW THAT MY VEHICLE WAS NOT PRODUCED WITH THIS FAULTY PIN IN THE CRANKSHAFT THAT CAUSES BEARING FAILURE? THANK YOU VERY MUCH FOR THIS WEBSITE AND I HOPE SOMEONE CAN ENLIGHTEN ME AS TO WHAT I MAY BE ABLE TO DO RIGHT NOW.

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.

AQ23002 · Hyundai And Kia Abs Module Fires

Opened Nov 17, 2023 · No close date supplied

Status: open (inferred from source dates) · Service Brakes, Hydraulic:antilock/traction Control/electronic Limited Slip:control Unit/module

The Office of Defects Investigation (ODI) has received eight Hyundai Motor America (Hyundai) and eight Kia America, Inc. (Kia) Part 573 Recall Reports between 2016 and 2023. The combined 16 safety recalls all involve the antilock braking system (ABS) modules or Hydraulic Electronic Control Units (HECU) manufactured by the equipment supplier Mando. The Part 573 Recall Reports contain varying defect descriptions and differing remedy descriptions for the same or similar equipment supplied by Mando. Safety recalls included in this Audit Query (AQ) review include: Hyundai recalls 20V-520, 20V-543, 21V-161, 21V-160, 21V-303, 22V-056, 22V-810, and 23V-651. Kia recalls 16V-815, 20V-518, 20V-519, 21V-137, 21V-331, 22V-051, 22V-800, and 23V-652 The purpose of this AQ is to evaluate the timeliness and scoping of Hyundai and Kia’s defect decision making and adherence with reporting requirements; and understand the varying defect descriptions and remedies between these recalls.

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.
