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.

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.
