I TOOK MY SON TO SCHOOL ON THURSDAY MORNING 12/8/2016. I WAS AT A STOP SIGN TO PULL OUT ONTO A MAIN HIGHWAY. THERE WAS A LINE OF CARS COMING BUT THEY WERE FAR ENOUGH AWAY I THOUGHT I COULD GO. I STARTED TO GO BUT CHANGED MY MIND AND LET OFF THE ACCELERATOR. I DECIDED TO GO AHEAD AND GO BUT THIS TIME THE ENGINE REVVED WAY UP AND THE CAR PULLED OUT ONTO THE HIGHWAY VERY SLOWLY. NOW IN A PANIC, I LET OFF THE ACCELERATOR AGAIN AND IMMEDIATELY PUSHED IT DOWN AGAIN. THANKFULLY, THE CAR LURCHED FORWARD AND TOOK OFF. THERE WAS THEN A STRANGE SMELL IN THE CAR WHICH I BELIEVE TO BE FROM THE CLUTCHES SLIPPING.

THIS HAPPENED FOR MONTHS, I CALLED THE DEALER AND THEY BRUSHED OFF. TWO WEEKS AGO WHILE TRYING TO MERGE ON THE HIGHWAY, I PRESSED THE GAS BUT THE CAR WOULD NOT MOVE ONLY REVVED THEN OUT OF NOWHERE IT LAUNCHED AND ALMOST HIT ANOTHER CAR. THEN TODAY, IT LITERALLY WENT DEAD?DEAD! WHILE DRIVING AT 25 MPH ON FORDHAM RD (A BUSY STREET THE BRONX) THE CAR SLOWLY LOST POWER AND STOPPED FOR 2-3 SECONDS. THEN START UP AGAIN. THIS CAR IS A DEATH TRAP!!! SOME ONE COULD HAVE RUN IN THE BACK OF MY CAR. I HAVE BEEN TO THE DEALER TWICE AND THEY CLAIMED TO FIX THE DCT BUT THAT'S CRAP. HYUNDAI WHO HAS DONE NOTHING AND THEY KNOW THIS VEHICLE IS UNSAFE. I CANT EVEN DRIVE MY 2 YR GODDAUGHTER IN THIS THING. I THINK HYUNDAI IS WAITING FOR SOMEONE TO DIE. THEY NEED TO STOP SELLING THIS CAR IMMEDIATELY AND REFUND EVERYONE'S MONEY. *TR

INTERMITTENT ACCELERATION ISSUES. UPON TRYING TO ACCELERATE FROM A STOP, THE CAR STARTS TO GO BUT WILL NOT ACCELERATE EVEN WITH THE GAS PEDELL TO THE FLOOR. THIS IS A DANGEROUS SITUATION IF YOU ARE TRYING TO MERGE INTO TRAFFIC. AS WAS THE CASE THE LAST TIME THE VEHICLE DID IT, ALMOST CAUSING A CRASH.

THE VEHICLE IS HYUNDAI'S NEW FUEL CELL MODEL. ON 3 SEPARATE OCCASIONS OVER 7 MONTHS THE VEHICLE LOST POWER WHILE ON A HIGHWAY. THE LAST OCCASION, NOVEMBER 7, 2016, I WAS IN THE LEFT LANE NEAR THE FAST LANE ON THE GLENDALE FREEWAY AT ABOUT 9:30 AM. THE VEHICLE SUDDENLY LOST POWER AND, SINCE THERE IS NO LEFT HAND SHOULDER, I HAD TO COAST ACROSS SEVERAL LANES OF FAST MOVING TRAFFIC TO TRY TO REACH AN EXIT RAMP. AFTER SEVERAL MINUTES OF NOT KNOWING WHAT WAS HAPPENING TO THE VEHICLE, I GAVE THE GEAR SHIFT LEVER A NUDGE TO THE RIGHT. I HEARD A SLIGHT MECHANICAL SOUND AND THE TRANSMISSION RE-ENGAGED AND I REGAINED FULL POWER. THE VEHICLE HAD NEARLY A FULL TANK OF FUEL AT THE TIME. THIS SAME THING HAPPENED TO ME IN THE APRIL/MAY TIME FRAME WHEN DRIVING ON A HIGHWAY IN SAN DIEGO COUNTY (ABOUT 1/2 TANK OF FUEL) AND THEN AGAIN IN EARLY JULY, 2016. WHEN I WAS DRIVING ON THE GOLDEN STATE FREEWAY NEAR GRIFFITH PARK (NOT SURE OF THE FUEL THIS TIME). BOTH TIMES, WITHOUT WARNING, THE VEHICLE SUDDENLY LOST POWER. IT COASTED FOR SEVERAL SECONDS BUT THESE TWO TIMES -- AFTER LESS THAN A MINUTE -- THE POWER REENGAGED, OR SELF CORRECTED, ON ITS OWN. THE NOVEMBER 7TH INCIDENT LASTED SEVERAL MINUTES, AND THE ENGINE DID NOT SELF CORRECT. ON NOVEMBER 8TH, I DROVE THE VEHICLE TO KEYES HYUNDAI IN VAN NUYS. SINCE IT HAD BEEN OVER 4 MONTHS AND SEVERAL THOUSAND MILES SINCE THE SECOND INCIDENT, I WAS NOT SURPRISED THAT THEY COULD NOT DUPLICATE THE TRANSMISSION FAILURE. I DO NOT BELIEVE THE VEHICLE IS SAFE TO DRIVE, HOWEVER, AND, SINCE THEY HAVE NOT BEEN ABLE TO IDENTIFY AND CORRECT THE DEFECT, HAVE ASKED HYUNDAI TO CANCEL THE LEASE ON THE VEHICLE RATHER THAN CONTINUE TO RISK MYSELF AND MY FAMILY IN THIS VEHICLE.

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.
