WHEN I ACCELERATE THERE IS NO POWER FOR 1-2 SECONDS, AND THIS IS NOT THE SAME THING AS THE SLIGHT DELAY EXPERIENCED AS THE CAR CHANGES GEARS. IT IS A COMPLETE LACK OF POWER EVEN WHEN THE GAS PEDAL IS PUSHED. VERY ALARMING. THE PROBLEM IS BECOMING MORE FREQUENT OVER THE PAST TWO MONTHS OF USE (1ST TIME IN JANUARY - LATER TIMES IN FEB. AND MARCH--WINTER IN THE MIDATLANTIC REGION). HAPPENS AT SLOWER SPEEDS (ACCELERATING AT 25-30MPH TO CROSS LANES OF CITY TRAFFIC), AND IT HAPPENS AT HIGHER SPEEDS (ACCELERATING AT 50-65MPH TO MERGE INTO INTERSTATE HIGHWAY TRAFFIC OR OVERTAKE A SLOWER CAR IN SAME LANE ON INTERSTATE). BECAUSE I DO NOT DRIVE THE CAR VERY OFTEN, AND MOST OF MY TRIPS ARE AT SLOW SPEEDS FOR SHORT DISTANCES, I INITIALLY OVERLOOKED/DISMISSED THE PROBLEM. BUT IS IT BECOMING MORE NOTICEABLE (LONGER PERIOD WITHOUT ACCELERATION POWER), MORE FREQUENT (OCCURS MORE OFTEN WHEN USING THE CAR) AND DANGEROUS (CAN HAPPEN ANYWHERE, ANY TIME AND AT ANY SPEED). I SUSPECT I AM REPORTING THIS PROBLEM LATER THAN OTHER TUCSON CAR OWNERS BECAUSE I DO NOT DRIVE MUCH. I'VE OWNED THE CAR FOR 11 MONTHS AND IT HAS 3,700 MILES ON IT. PROBLEMS STARTED SHOWING UP AROUND 3,500 MILES.

SINCE PURCHASING THE VEHICLE IN NOVEMBER 2015, THE VEHICLE HAS HAD DIFFICULTY SHIFTING AT LOWER SPEEDS AND ACCELERATING AT HIGHER SPEEDS. INITIALLY, THE DEALERSHIP TOLD ME I JUST NEEDED TO GET USED TO DRIVING A TURBO. I HAVE HAD ALL THREE UPDATES DONE TO THE DUAL-CLUTCH TRANSMISSION. AFTERWARDS, IN JANUARY 2017, WHILE DRIVING IN THE CITY, THE VEHICLE DROPPED INTO NEUTRAL BETWEEN FIRST AND SECOND GEAR. THE RPMS REVVED UP TO 4, BUT THE VEHICLE HAD A SUDDEN LOSS OF FORWARD MOMENTUM. BECAUSE I WAS IN HEAVY TRAFFIC, THIS PRESENTED A SAFETY HAZARD TO ME. THE DEALERSHIP RE-PERFORMED THE DECEMBER 2016 UPDATE THE FIRST PART OF FEBRUARY 2017 AND CAUSED A FULL SYSTEM FAILURE REQUIRING MANUAL REPROGRAMMING. IT THEN RELEASED THE VEHICLE BACK TO ME. AFTER TWO DAYS, THE SAME THING HAPPENED WHILE DRIVING IN THE CITY. I WAS AGAIN IN HEAVY TRAFFIC AND AFRAID ABOUT BEING REAR-ENDED. WHEN THE CAR REENGAGED AFTER THESE FAILURES, IT THEN SURGED FORWARD. THE PROBLEM IS INTERMITTENT AND THEREFORE UNPREDICTABLE AND UNSAFE. THE DEALERSHIP INFORMED ME IT HAS NOT BEEN UNABLE TO DUPLICATE THE PROBLEM AND THUS HAS NOTHING TO FIX. ADDITIONALLY, IT HAS BEEN IN TOUCH WITH HYUNDAI CORPORATE WHOSE POSITION IS THAT THE PROBLEM WAS FIXED WITH THE DECEMBER 2016 UPDATE. AND, SINCE THE DEALER HASN'T DUPLICATED IT, THEY HAVE NO FURTHER OBLIGATION TO ME. ACCORDING TO THE DEALERSHIP, HYUNDAI CORPORATE KNOWS OF NO OTHER CAR IN THE NATION STILL HAVING TRANSMISSION PROBLEMS AFTER THE DECEMBER 2016 UPDATE. IN ADDITION TO MY COMPLAINT, PLEASE REVIEW NHSTA 10948958, 10939802, 10938874, 10939196, AND 10946886 TO TEST THE CREDIBILITY OF ITS ASSERTION.

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.
