THE REAR PASSENGER DOOR (THEN A DAY LATER'DOORS) WON'T OPEN FROM THE INSIDE OR OUT EVEN WHEN MANUALLY UNLOCKED WHETHER OR NOT THE CAR IS ON OR OFF. WE WERE ON A TRIP AT THE TIME AND OUR KIDS WERE HAVING TO CRAWL OVER FROM THE FRONT SEAT. WE CALLED HYUNDAI. THEIR TEMPORARY FIX WAS TO UNLOCK THE CAR AND JERK THE HANDLE HARD FROM THE OUTSIDE. THEY SAID THAT THE SYSTEM SOMETIMES' FREEZES UP'. THIS WORKS FROM THE OUTSIDE (NOT INSIDE), AND CONTINUES TO FREEZE UP EVEN AFTER ' THE HYUNDAI FIX'. THIS IS A PROBLEM WITH OTHER 2016 HYUNDAI MODELS. IF YOU LOOK UP THE PROBLEM ONLINE, YOU WILL SEE MANY POSTS ABOUT IT.

THE REAR PASSENGER DOOR OF MY 2016 HYUNDAI TUCSON NO LONGER OPENS AT ALL, FROM THE INSIDE OR THE OUTSIDE. AS I HAVE A YOUNG CHILD AND NEPHEWS WHO ARE REGULARLY IN MY CAR IN CAR SEATS, THIS IS A SERIOUS SAFETY CONCERN. APPARENTLY, HYUNDAI IS NOT WILLING TO TAKE RESPONSIBILITY FOR THIS DEFECT, WHICH I HAVE FOUND IS A PROBLEM ACROSS MANY HYUNDAI YEARS AND MODELS.

1.DRIVER SIDE REAR PASSENGER DOOR WOULD NOT OPEN FROM OUTSIDE OR INSIDE. IT EVENTUALLY WORKED BY PULLING REALLY HARD FROM OUTSIDE. 2. DRIVER'S DOOR WILL NOT OPEN FROM OUTSIDE BUT WILL FROM INSIDE. IT IS OBVIOUSLY UNLOCKED WHEN TRYING TO OPEN. THE ACTUATOR IS THE MOST LIKELY COMPONENT THAT IS FAILING. THE MECHANISM WILL NOT UNLOCK THE DOOR WITH THE KEY EITHER. THIS IS A HUGE SAFETY ISSUE WHEN IT'S 100 DEGREES OUTSIDE AND I CAN'T GET A CHILD OUT OF THE BACKSEAT. OR FOR FIRST RESPONDERS SENT TO AID SOMEONE TRAPPED IN THE CAR. I'VE READ OF MULTIPLE FAILURES AFTER SEARCHING FOR THIS PROBLEM ON THE INTERNET. IT HAPPENS A LOT TO MANY HUNDAI MODELS OVER THE PAST 6-8 YEARS.

THREE OF THE FOUR DOORS HAVE DEFECTS WHICH PREVENT THEM FROM OPENING FROM THE OUTSIDE OR INSIDE, WHICH IS A MAJOR SAFETY CONCERN. THE DOOR LOCK ACUATOR IS WHAT NEEDS TO BE REPLACED. THE RIGHT FRONT DOOR WAS REPLACED IN 2018. ONE OF THE BACK DOORS WAS REPLACED IN 2020, AND NOW THE OTHER BACK DOOR WON'T OPEN DUE TO THE SAME ISSUE. I OFTEN TRANSPORT CHILDREN AND AN ELDERLY GRANDPARENT, ALL OF WHOM SIT IN THE BACK SEAT. IF I HAD BEEN IN AN ACCIDENT, THERE WOULD BE NO WAY TO GET THEM OUT OF THE VEHICLE. ON TOP OF THE FACT THAT THIS IS CLEARLY A MANUFACTURER DEFECT WITH THE VEHICLE, I'M NOW CONCERNED THE DRIVER'S DOOR WILL STOP WORKING SOON, MEANING I CAN'T DRIVE THE VEHICLE AT ALL. I CONTACTED HYUNDAI CUSTOMER SUPPORT SINCE THE VEHICLE IS 1,000 MILES OVER WARRANTY AND THEY SAID THERE IS NOTHING THEY CAN DO (CONVERSATION 4/5/21). FIVE STAR HYUNDAI OF MACON REFUSED TO PUT IN A REQUEST TO OVER-RIDE THE WARRANTY TO GET IT FIXED, SINCE CLEARLY IT IS A MANUFACTURER PROBLEM WITH MY VEHICLE. THE VEHICLE HASN'T BEEN IN ANY ACCIDENTS THAT WOULD HAVE CAUSED THIS ISSUE AND HYUNDAI IS APPARENTLY AWARE OF THE ISSUE, AS IT FREQUENTLY OCCURS WITH TUCSONS AND ELANTRAS (PER CONVERSATION WITH FIVE STAR HYUNDAI), YET REFUSES TO DO ANYTHING ABOUT IT. BECAUSE MY VEHICLE IS NOW AT 61,000 MILES THEY ARE SAYING IT IS NO LONGER THEIR RESPONSIBILITY AND ARE NOT OFFERING TO ASSIST IN ANY WAY. THE BLIND SPOT DETECTOR IS ALSO MALFUNCTIONING, NOT NOTIFYING WHEN A VEHICLE IS NEXT TO MINE AND OCCASIONALLY GOING OFF WHEN THERE IS NO VEHICLE AT ALL. FIVE STAR MACON SAID THIS IS ALSO NOT UNDER WARRANTY ANYMORE AND SAID THEY DON'T KNOW WHY IT WOULD BE A PROBLEM BUT WOULD REQUIRE THEM REMOVING MY BUMPER AND DOING EXTENSIVE DIAGNOSTIC WORK BEFORE THEY'D KNOW HOW TO FIX IT.

1DP22003 · 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.
