THIS COMPLAINT HAS TO DO WITH THE AEB ( AUTOMATIC EMERGENCY BRAKING ) SYSTEM. THIS WAS A FEATURE THAT LED ME TO PURCHASE THE CAR AND I DISCUSSED IT WITH THE SALESMAN AT LENGTH AT THE TIME I PURCHASED IT. SHORTLY AFTER PURCHASING THE CAR, I STARTED TRYING TO TEST IT TO SEE IF AND HOW IT WORKED. I COULD GET NO INDICATION IT WAS WORKING WITHOUT WRECKING IT. THERE IS SUPPOSED TO BE 3 WARNING STAGES ACCORDING TO THE MANUAL ( 1 A MESSAGE ON LCD WITH WARNING ALARMS, 2 A 2ND COLLISION WARNING MESSAGE AND LIMITED CONTROL OF THE BRAKES, 3 EMERGENCY BRAKING ). I NEVER SAW ANY OF THESE. I TOOK IT BACK TO THE DEALER ALONG WITH A VIDEO IN WHICH I TESTED IT RUNNING OVER PARTY BALLOONS. THEY SAID IT WAS WORKING AS DESIGNED. I WROTE HYUNDAI AMERICA AND THEY SUGGESTED I TAKE TO ANOTHER DEALER WHICH I DID AND THEY SAID THE SAME THING. NO ONE CARES OR IS INTERESTED IN SEEING THAT THE SYSTEM WORKS. I HAVE ATTACHED A COUPLE OF STILL PHOTOS I TOOK FROM MY VIDEO SHOWING JUST BEFORE AND AFTER THE COLLISION WITH THE BALLOONS. I HAVE SEVERAL VIDEOS, I COULD SEND IF INTERESTED. THANK YOU

THE SANTA FE SPORT WAS PURCHASED IN JULY OF 2017. WHEN TAKING OFF FROM A REDLIGHT OR WHILE DRIVING AT A STEADY MOMENTUM ON THE ROAD, THE ACCELERATION DROPS SIGNIFICANTLY AND THE RPMS BEGIN TO REV UP HIGH, BOUNCING UP AND DOWN, BUT THE SANTA FE SPORT WILL STALL. WHILE ON THE HIGHWAY, THE ISSUE CONTINUES AND PANIC SENTS IN DUE TO THE CARS BEHIND US CAN REAR END THE SANTA FE SPORT. NO MATTER HOW FAR OR HARD THE GAS PEDAL IS PRESSED THE SANTA FE SPORT WILL STALL. ALL WHILE NO "ENGINE LIGHT" TURNS ON. TOOK THE SANTA FE SPORT FOR SERVICE TO THE DEALER OVER 6 TIMES BETWEEN 2017 AND 2018 AND ONLY AN EMS PART WAS REPLACED. THE PROBLEM CONTINUES MOSTLY IN VERY BAD TRAFFIC, AGAIN VERY CONCERNING FOR SAFETY. THE SANTA FE SPORT NEEDS TO BE TURNED OFF AND BACK ON IN ORDER FOR THE PROBLEM TO CEASE. NO MATTER WHAT DRIVE MODE IT IS IN (ECO; SPORT; NORMAL) THE ISSUE PERSISTS. WE PURCHASED A BRAND NEW 2017 SANTA FE SPORT RIGHT OFF THE LOT WHICH HAS BEEN PAID FOR AND IT IS UNFAIR THAT WE ARE STILL PAYING WHAT SEEMS LIKE OUR LIVES WE CONTINUE TO SPEND MORE WITH GAS, TOLLS, TRAVEL AND TIME FROM WORK TO TAKE THE SANTA FE SPORT IN FOR SERVICE AND WE DO NOT GET REFUNDED FOR THIS.
I WAS PULLING ONTO THE HIGHWAY AND COMING UP TO SPEED, GOING APPROXIMATELY 50 MILES PER HOUR, WHEN I HEARD A LOUD NOISE, LIKE A 'CRACK' OR A 'BOOM.' IT QUICKLY BECAME CLEAR THAT MY GLASS SUNROOF HAD BURST AND THERE WERE GLASS PIECES RAINING DOWN ON THE SUN SCREEN, WHICH THANKFULLY HAD BEEN CLOSED. NO INJURIES WERE SUSTAINED.

PURCHASED CAR IN JUNE 2017 AND CURRENTLY HAVE APPROX. 5100 MILES. WHEN GOING FROM A STANDSTILL STOP OR A SLOW ROLLING START (EXITING A DRIVEWAY) THE ACCELERATION IS LACKING. CAR WILL GO HIGH RPMS BUT NO SPEED. AND WHEN ATTEMPTING TO MERGE ONTO A ROAD WAY IT HAS BECOME A SAFETY CONCERN AS APPROACHING CARS FROM THE REAR CLOSE WHAT WAS A SAFE DISTANCE TO BEING ON TOP OF THE BUMPER IN NO TIME SINCE I CAN NOT ACCELERATE. 0-40 CAN TAKE UPWARDS OF 30 SECONDS WITH PEDAL DEPRESSED FULL. CAR WAS TAKEN IN FOR SERVICE AT DEALER IN DECEMBER 2017 AND WAS "CORRECTED". NOW THE PROBLEM HAS BECOME WORSE AND CAR WILL PRODUCE PROBLEM MORE FREQENTLY AND IN ANY DRIVING CONDITION TO INCLUDE BEING IN TRAFFIC. THE ONLY WAY I CAN SOMEWHAT CORRECT THE ISSUES (AND FIGURED IT OUT DURING TRIAL AND ERROR) IS TO TURN THE DRIVE MODE TO SPORT AND TURN OFF TRACTION CONTROL. WHEN CAR IS IN ECO THE PROBLEM IS MUCH MORE SERVE AND IN NORMAL IT FREQUENTLY HAPPENS. I DO NOT FEEL I SHOULD HAVE TO ADJUST OR TURN OFF SYSTEMS IN A VEHICLE TO MAKE IT SAFE TO DRIVE NOR SHOULD I HAVE A VEHICLE I CAN NOT DRIVE AT SAFE SPEEDS.

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.
AQ23002 · Hyundai And Kia Abs Module Fires

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.
