THE REAR DRIVER'S SIDE DOOR LATCH FAILED SUDDENLY AND WITHOUT WARNING ON MY DAUGHTER'S 2016 HYUNDAI TUCSON. THE DOOR COULD NOT BE OPENED FROM THE INSIDE OR OUTSIDE OF THE VEHICLE. NOT BEING ABLE TO OPEN THE CAR DOOR COULD HAVE LED TO SO MANY HEALTH AND SAFETY ISSUES DEPENDING ON THE SITUATION. PLEASE IMAGINE IF THE DRIVER'S DOOR FAILED DURING A VEHICLE FIRE, A SUBMERGED SITUATION, A CAR CRASH, ETC. THINK OF THE POSSIBILITIES OF YOUR CHILD DRIVER BEING TRAPPED IN THE CAR DURING A SITUATION LIKE I JUST MENTIONED. AS YOU CAN EXPECT, I'M VERY DISAPPOINTED IN THE DEFECT AND I'M SHOCKED THERE IS NO RECALL OR FREE REPAIR AVAILABLE FOR THIS SERIOUS SAFETY ISSUE. I'VE PURCHASED THIS VEHICLE BASED ON THE EXCELLENT RATINGS OF QUALITY AND SAFETY. FROM WHAT I UNDERSTAND, EACH OF THE DOOR LATCHES COULD SUBSEQUENTLY FAIL AS WELL AS THE NEW LATCH RECENTLY INSTALLED. THIS IS UNACCEPTABLE. I'M NEARLY 60 YEARS OLD AND HAVE OWNED OVER A DOZEN CARS IN MY LIFE. THIS IS THE VERY FIRST FAILED DOOR LATCH I'VE HAD AND HAVE EVER HEARD OF.

REAR PASSENGER DOORS WON'T OPEN FROM INSIDE OR OUTSIDE DOOR HANDLES. THIS STARTED INTERMITTENTLY THEN ULTIMATELY TRAPPED PASSENGERS IN THE REAR SEATS OF THE VEHICLE. NOTHING WORKED TO RELEASE THE DOORS, CAUSING PASSENGERS TO HAVE CRAWL THROUGH FRONT SEATS TO EXIT THE VEHICLE. INVESTIGATING OF ANY RECALLS WE FOUND THAT THIS IS WIDE SPREAD OVER SEVERAL YEARS, AND CHARGES RANGE FROM $400 TO $2K. WHEN CLEARLY THIS IS DEFECTIVE COMPONENTS OR DESIGN, USED IN AND FOR LOCKING SYSTEM, FAIR EXPECTATION THAT OCCUPANTS CAN EXIT THE VEHICLE IN THE CASE OF AN EMERGENCY. HYUNDAI SERVICE CONSIDERS THIS A MALFUNCTIONING PART AND NOT COVERED BY WARRANTY OR BY AGE OF THE VEHICLE. THE DOORS LOCKING ACTUATORS ARE MALFUNCTIONING THERE IS NO OPTION TO MANUALLY OPEN THE DOORS, AGAIN CAUSING A PERSON TO BE TRAPPED IN THE VEHICLE. PEOPLE ARE REPORTING FROM 1 DOOR TO ALL 4 DOORS FAILING TO OPEN. OUR CAR THE REAR DOORS DO NOT OPEN. HYUNDAI SHOULD TAKE RESPONSIBILITY TO FIX THIS DEFECTIVE PART/DESIGN AND NOT AT THE CAR OWNERS EXPENSE.

THIS IS A TOTAL SAFETY ISSUE, BECAUSE IF I WERE TO GET INTO AN ACCIDENT AND MY ONLY WAY OUT WAS THE DOOR I WOULD BE LOCKED IN AND POTENTIALLY DIE. THE FACT THIS HAS BEEN AN ISSUE FOR PEOPLE FOR OVER A YEAR AND STILL NOT A RECALL AND FOR IT TO HAPPEN TO ME TWICE IS RIDICULOUS. MY DAD IS A FIRST RESPONDER AND SAYS THAT THIS ISN'T A RECALL IS UNACCEPTABLE. AND THE FACT THAT THE ONLY WAY IT WILL BE A RECALL IS FOR SOMEONE TO DIE IN THE ACCIDENT AND FOR THEM TO SUE HYUNDAI TO BE A RECALL IS RIDICULOUS. PLEASE CONSIDER THE DOOR LATCH ISSUE TO BE A RECALL YOU CAN SEE ALL THE OTHER COMPLAINTS ONLINE BY TYPING IN GOOGLE.

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.
