THE DEALERSHIP HAS DONE 4 UPDATES TRYING TO CORRECT THE ISSUE BUT IT STILL OCCURS. ALL MANAGEMENT OF THE DEALERSHIP HAVE DRIVEN THIS VEHICLE AND AGREE THAT THERE IS DEFINITELY A PROBLEM. THE SERVICE MANAGER PUT HIS FOOT ON THE BRAKE AND THE GAS AS A DEMONSTRATION TO ME AND THE VEHICLE DIES OUT EVERY TIME. THEY DO NOT KNOW HOW TO FIX THE PROBLEM. THE RECALL DUE OUT ON OCTOBER 28, 2016 WAS ALREADY DONE ON SEPTEMBER 27, 2016 AND DID NOT CORRECT THE ISSUE.

WHILE DRIVING THE VEHICLE IN NORMAL AROUND TOWN TRAFFIC, WE HAVE HAD SEVERAL INCIDENTS WHERE AN ALARM BEGAN SOUNDING, AND THE INSTRUMENT PANEL DISPLAYED "TRANSMISSION TEMPERATURE IS HIGH! STOP". WE'VE TAKEN THE VEHICLE TO HAVE THE DEALER INVESTIGATE, BUT THEY FIND NOTHING, CAN'T DUPLICATE IT, AND NO INDICATION THAT IT EVEN DISPLAYED THE WARNING. THEY SAID IT MIGHT BE RELATED TO THE CURRENT RECALL FOR THE DCT TRANSMISSION ON THE HYUNDAI TUCSON. I'VE CONTACTED HYUNDAI AND TRIED TO ASK IF THE DEALER MAY BE CORRECT, BUT THEY SAID THEY CAN ONLY REFER ME BACK TO THE DEALER. IT CAN BE DIFFICULT AND UNSAFE TO FIND A PLACE TO "STOP SAFELY" AT THE DROP OF A HAT AS IT DEMANDS.

I PURCHESED MY NEW 2016 HYUNDAI TUSCON TURBO IN FEB. I HAVE HAD NOTHING BUT PROBLEMS WITH IT. IT HAS ALWAYS BEEN SLUGGISH ON ACCELARTION AND AT TIMES WON'T MOVE AT ALL AFTER A STOP. IT HAS HAD NUMEROUS "UPDATES" FOR THE TRANSMISION WITH NO SUCCESS. AT TIMES IT WILL ROLL BACKWARDS WHEN IN DRIVE AS IF IT IS IN NEUTRAL WHILE AT DRIVE THRUS OR ON AN INCLINE . IT REMAINED IN THE SHOP FOR ONE OF THE TIMES FOR MORE THAN 30 DAYS. A HYUNDAI ENGINEER HAS INSPECTED MY CAR AND SAYS THAT THERE IS NOTHING WRONG IT. ALL OF THE ISSUES I HAVE HAD ARE NOT NORMAL, AND THEY AGREE BUT STATE THAT THERE IS NOTHING WRONG WITH IT. THE SERVICE DEPT HAVE DRIVEN MY CAR AND AGREE THAT IT STILL HAS THE HESITATION, BUT SAY THEIR HANDS ARE TIED UNTIL HYUNDAI HAS A SOLUTION. IT DOESN'T THROW A CODE ON ANY OF THE ISSUES. IT HAS EVEN DIED WHILE DRIVING DOWN THE ROAD. IT HAS BEEN IN THE SHOP REPEATEDLY FOR THE SAME ISSUES. NOW, THIS LAST TIME, I AM GETTING A BATTERY DISCHARGE WARNING WHILE DRIVING DOWN THE HIGHWAY. IT IS NOW BACK IN THE SHOP FOR THAT ISSUE ALONG WITH THE SAME SLUGGISH DELAYED ACCELEARTION. I AM 100% UNHAPPY WITH THIS PURCHASE. I SEE WHERE HUNDAI IS MAKING A RECALL, BUT I AM UNSURE IF THIS NEW UPDATE IS ANY DIFFERENT FROM THE OTHER TWO MY SUV HAS ALREADY HAD. THIS CAR IS UNSAFE TO DRIVE AND CERTAINLY HAS MAJOR ISSUES.

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.
