I WAS AN OWNER OF A 2016 HYUNDAI TUCSON WITH TURBO. UNTIL JANUARY 23, 2018. I OWNED THIS VEHICLE FOR MORE THAN A YEAR AND ALTHOUGH THIS WAS A GREAT VEHICLE WE HAD AN ISSUE WITH THE TRANSMISSION SINCE A WEEK AFTER OUR PURCHASE DATE.WE HAVE HAD IT BACK TO THE SERVICE DEPARTMENT AT WRIGHT WAY HYUNDAI IN STAUNTON, VA NUMEROUS TIMES OVER THE SAME ISSUE. THE TRANSMISSION WOULD ALLOW THE MOTOR TO SEND THE RPMS TO EXCEED A HIGH LEVEL BEFORE ENGAGING. SO BAD AT TIME THAT IT WOULD PULL YOU TO ONE SIDE OF THE ROAD OR THE OTHER, ALSO FROM A STOP IT WOULD REV UP SO BAD THAT IT WOULD TAKE OFF SPINNING. I HAVE CONTACTED HYUNDAI OVER THIS MATTER INCLUDING OTHER DEALERSHIPS. I HAVE BEEN TOLD EVERYTHING FROM 'THAT'S THE WAY IT WAS DESIGNED' TO 'YOU HAVE TO LEARN HOW TO DRIVE IT'. IT ALWAYS WOULD COME DOWN TO THAT IT WAS THE WAY WE WERE DRIVING IT. I'M SORRY BUT A TRANSMISSION SHOULD NOT RESPOND IN THAT MATTER. I ALSO WAS TOLD BY A HYUNDAI REP. THAT THEY HAVE HAD MANY COMPLAINTS OVER THE SAME ISSUE.I WAS TRAVELING DOWN THE ROAD AND WAS APPROACHING A CURVE WHEN I LIFTED MY FOOT OFF THE ACCELERATOR AND WHEN I WENT BACK TO THE ACCELERATOR THE RPMS SHOT UP. IT WOULDN'T GO. I PUSHED AGAIN, AND THE RPMS SHOT UP AND THEN SUDDENLY IT ENGAGED AND WHEN IT DID I WAS PULLED LEFT ACROSS THE ONCOMING LANE AND OVER A STEEP 30-FOOT EMBANKMENT INTO ABOUT 5 FEET OF VERY COLD WATER. I WAS TAKEN TO THE HOSPITAL IN AN AMBULANCE AND I WAS CHECKED OUT WITH MINOR INJURIES. AND NO I WASN'T SPEEDING.

ONCE THE CAR IS TURNED OFF, THE PROBLEM IS INTERMITTENT AND THE DEALERSHIP HAS NOT BEEN ABLE TO RECREATE IT. BROUGHT IT TO THE DEALERSHIP 3X. IT IS VERY DANGEROUS. I BOUGHT THIS CAR NEW AND AM NOW WONDERING HOW I WILL CONTINUE TO DRIVE A CAR THAT COULD KILL ME. VERY UPSETTING. ALSO, IT IS A WELL DOCUMENTED PROBLEM AND NO ONE SEEMS TO BE DOING ANYTHING ABOUT IT.

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.
