WHEN TRYING TO GET INTO MY CAR, I UNLOCK MY DOORS. WITH ALL DOORS UNLOCKED I TRY TO ENTER THE DRIVER DOOR FROM THE OUTSIDE. IT TAKES MULTIPLE POOLS ON THE HANDLE FOR THE DRIVE DOOR TO GET THE LATCH INSIDE THE DOOR TO RELEASE AND OPEN THE DOOR. MY DOOR BECOMES STUCK AND I AM UNABLE TO GET INSIDE MY VEHICLE. THIS CAN BE A POTENTIAL SAFETY ISSUE, IN DARK PARKING LOTS, UNSAFE LOCATIONS, PREVENTING ME FROM GETTING IN MY VEHICLE. I TOOK MY VEHICLE TO HYUNDAI DEALER. THEY STATES NOTHING IS WRONG WITH MY DOOR AND IT WORKS FINE. THIS WAS APPROX APR IN 2020. BEGINNING THIS WEEK MY PASSENGER SIDE FRONT DOOR WILL NOW ALSO NOT OPEN FROM THE OUTSIDE, EVEN IF MY DOOR IS UNLOCKED. NO MATTER HOW MANY TIMES I PULL THE HANDLE THE PASSENGER DOOR WONT RELEASE FROM THE OUTSIDE. I HAVE TO OPEN THE DOOR FROM THE INSIDE.

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.

I HAVE HAD A PROBLEM OPENING UP MY DRIVER SIDE BACK DOOR SENSE SUMMER OF 2020 SO I'VE TAKEN THE BACK DOOR PANEL OFF AND I PULL ON THE WIRE FROM THE INSIDE TO OPEN IT UP. I'VE DEALT WITH THAT JUST FINE IT'S IRRITATING BUT NOW MY PASSENGER SIDE FRONT IS NOT WANTING TO OPEN FROM THE OUTSIDE DO I HAVE TO READ ACROSS AND OPEN UP THE DOOR IF ANYBODY IS GOING TO BE ON THE PASSENGER SIDE. NOW THE DRIVER'S SIDE DOOR HAS STARTED DOING IT. SO NOW I'M EXPECTED TO CLIMB IN TRUE THE PASSENGER REAR DOOR AND UP INTO THE FRONT SEAT OR OPEN THE DOOR FROM THE INSIDE AND THEN WALK BACK AROUND MY CAR. THAT IS UNTIL THE BACK PASSENGER DOOR DECIDES TO START DOING THE SAME THING AND THEN I GUESS I'LL HAVE TO CLIMB IN THROUGH THE TRUNK? OR MAYBE THAT'LL BE THE NEXT ONE TO GO? ANOTHER ISSUE THAT HAVE BEEN HAVING A LOT OF TROUBLE WITH IS THE FRONT INTERIOR DOME OR THE CONSOLE THE PASSENGER SIDE LIGHT DOESN'T LIKE TO COME ON MOST OF THE TIME, BUT OCCASIONALLY IT DOES. THE BIGGEST ISSUE IS THE FRONT HEADLIGHTS AND THE BRAKE LIGHTS. SO THE HEADLIGHTS HAVE BEEN NEEDING TO BE REPLACED MORE OFTEN THAN I EVER HEARD OF ANYBODY REPLACING THEM, LESS THAN 6 MONTH SOMETIMES. OTHER TIMES THAT HAD LIKE JUST GOES OUT AND THEN I HAVE TO GET UNDER THE HOOD AND HOPEFULLY GET THE CAP OFF SO THAT I CAN PLAY WITH THE FITTING AND HOPE THAT IT WILL COME BACK ON. BECAUSE I ACTUALLY DO MOST OF MY DRIVING IN THE DARK WHEN IT'S NIGHT TIME SO I KIND OF NEED MY LIGHTS. SOMETIMES THAT DOESN'T WORK BUT THE NEXT MORNING I WILL TURN ON THE VEHICLE THE LIGHT IS WORKING AGAIN?... I'VE BEEN DEALING WITH THAT ISSUE FOR ABOUT A YEAR AS WELL. JUST RECENTLY WITHIN THE LAST FEW MONTHS BEE TAIL LIGHT OR BRAKE LIGHT HAS STARTED DOING THE SAME THING. SPECIFICALLY THE PASSENGER BRAKE LIGHT SO FAR. I COULD SENSE THERE WAS SOME SORT OF ELECTRICAL ISSUE COMING ON BUT WOULDN'T HAVE EXPECTED ALL OF THIS, BACK TO BACK AT THE SAME TIME.

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.
