516 reportsINTERMITTENT ISSUE WITH TRANSMISSION FAILING TO ENGAGE 1ST GEAR FROM A STOP. ENGINE REVS BUT NO POWER GOES TO THE WHEELS. HAPPENED THREE TIMES IN THE LAST TWO WEEKS ON A VEHICLE WITH 2500 MILES. RESTARTING THE VEHICLE RESOLVED THE ISSUE ONCE BUT NOT ON THE OTHER OCCASIONS.
FAILS TO FULLY ENGAGE GEARS, FEEL LIKE TRANSMISSION HAS SLIPPED OUT OF GEAR, WON'T ALWAYS GO INTO FIRST GEAR WHEN STARTING OUT. OR GOES INTO FIRST AND SECOND IS NOT THERE, NO POWER TO MOVE UNTIL FOOT IS LIFTED OFF ACCELERATOR, WAIT A FEW SECONDS THEN TRY AGAIN.
THE PROBLEM IS THE DUAL CLUTCH TRANSMISSION (DCT). AT TIMES, WHEN PROGRESSING FROM A STOP (STATIONARY), THE ENGINE RPM INCREASES NORMALLY BUT THE TRANSMISSION DOES NOT IMPART MOTION TO THE WHEELS. DEALER CANNOT DUPLICATE THE PROBLEM. THERE ARE NUMEROUS COMPLAINTS ON NHTSA WEBSITE AND ON THE HYUNDAI FORUM WEBSITE. HYUNDAI IS SILE…

THE PROBLEM IS THE DUAL CLUTCH TRANSMISSION (DCT). AT TIMES, WHEN PROGRESSING FROM A STOP (STATIONARY), THE ENGINE RPM INCREASES NORMALLY BUT THE TRANSMISSION DOES NOT IMPART MOTION TO THE WHEELS. DEALER CANNOT DUPLICATE THE PROBLEM. THERE ARE NUMEROUS COMPLAINTS ON NHTSA WEBSITE AND ON THE HYUNDAI FORUM WEBSITE. HYUNDAI IS SILENT ABOUT THIS PROBLEM. THIS IS A SERIOUS SAFETY DEFECT. HYUNDAI NEEDS TO RECALL THIS DCT FOR REPAIR/REPLACEMENT IMMEDIATELY.

ON FRIDAY, JUNE 17, MY TUCSON WAS PARKED OUTSIDE FROM 4 P.M. TO 7 P.M. AND THE OUTSIDE TEMPERATURE WAS IN THE LOWER 90'S. WE THEN GOT IN THE CAR AND DROVE APPROXIMATELY 2 MILES AT 25 MILES PER HOUR TO THE REAR GATE OF THE COMMUNITY. WE STOPPED AT THE REAR GATE TO WAIT FOR IT TO OPEN, HOWEVER IT DID NOT OPEN AS IT DID NOT SENSE THE PRESENCE OF THE CAR. SO I ATTEMPTED TO BACK UP BY PLACING THE CAR IN REVERSE AND DEPRESSING THE ACCELERATOR. THE CAR RPM WENT TO 4000 AND THE CAR DID NOT MOVE. SO I TOOK FOOT OFF THE ACCELERATOR, AND UPON DEPRESSING THE ACCELERATOR AGAIN, THE CAR RPM WENT TO AGAIN TO 4000 HOWEVER AGAIN THE CAR DID NOT MOVE. MY WIFE WAS WITH ME ASKING 'WHAT IS WRONG WITH THIS CAR IT IS NOT MOVING AND CARS ARE BEHIND US'. I THEN PLACED THE CAR IN PARK FOR ABOUT 30 SECONDS. THE GATE WAS NOW OPENED, SO I PLACED THE CAR IN DRIVE AND DEPRESSED THE ACCELERATOR. THE CAR RPM WENT TO 3000 TO 4000 AGAIN, HOWEVER THE CAR BEGAN TO MOVE EXTREMELY SLOWLY, UNDER 5 MPH. IT THEN SHIFTED, JERKING AS IT MOVED FORWARD AND SHIFTING. AFTER TRAVELING ABOUT 200 FEET THE CAR BEGAN TO SHIFT AND DRIVE IN A NORMAL MANNER. THIS IS THE 6TH OR 7TH TIME THIS HAS OCCURRED, HOWEVER USUALLY HAPPENS WHEN ATTEMPTING TO GO FORWARD FROM A STOP. THE CAR ACTS LIKE IT IS IN NEUTRAL AND DOES NOT MOVE, ENGINE REVS UP BUT DOES NOT MOVE. TAKEN THE CAR TO THE DEALERSHIP 3 TIMES, HOWEVER THE PROBLEM IS INTERMITTENT AND DOES NOT HAPPEN AT THE DEALERSHIP.. THE CHECK OUT THE CAR AND STATE THAT THEY FIND NO ERROR CODES AND THE CAR IS OPERATING NORMALLY.

WE RECENTLY PURCHASED THIS VEHICLE. AFTER DRIVING THIS VEHICLE TWO WEEKS, WE EXPERIENCED SEVERAL INSTANCES IN WHICH THE DCT TRANSMISSION FAILED. WHILE ATTEMPTING TO CROSS FOUR LANES OF TRAFFIC, VEHICLE STALLED WHILE ATTEMPTING TO ENTER TRAFFIC FLOW. IN ANOTHER CASE, THE VEHICLE FAILED TO RESPOND WHEN IT WAS PUT INTO REVERSE. SEVERAL OTHER OCCASIONS THE TRANSMISSION SLIPPED AND FAILED TO CHANGE GEARS. THIS CAR IS VERY UNSAFE AND WE HAVE NO CONFIDENCE IN HYUNDAI. THIS VEHICLE WAS RETURNED TO THE DEALERSHIP AND AT THAT TIME THEY FOUND NO PROBLEM. THE CAR IS CURRENTLY IS IN THEIR CARE, AWAITING FURTHER CONSULTATION FROM HYUNDAI CORPORATE. HOWEVER, WE WERE TOLD THERE IS NO CURRENT FIX FOR THE PROBLEM. WE ARE CURRENTLY DISMAYED AND MAY BE SEEKING LEGAL ADVICE..

JUST LIKE SO MANY OTHER COMPLAINANTS HERE: MY 2016 HYUNDAI TUCSON FAILED TO MOVE FORWARD AFTER BEING STOPPED AT A RED LIGHT AND ULTIMATELY HAD TO BE TOWED TO THE DEALERSHIP. THE DEALER "FIXED" THE ISSUE BY RESETTING THE TRANSMISSION MODULE. HOWEVER, THEY COULD NOT INDICATE WHY IT FAILED IN THE FIRST PLACE NOR COULD THEY GUARANTEE THAT IT WOULD NOT HAPPEN AGAIN. JUDGING BY THE NUMBER OF COMPLAINTS HERE AND AT HYUNDAI-FORUMS, THIS IS BECOMING A WIDESPREAD ISSUE THAT NEEDS TO BE ADDRESSED BY HYUNDAI. IT IS A POTENTIALLY DANGEROUS PROBLEM IF THE VEHICLE BECOMES IMMOBILE WHILE TURNING LEFT IN FRONT OF ONCOMING TRAFFIC.

IN TWO SEPARATE INCIDENTS ABOUT A MONTH APART, I WAS STOPPED AT A TRAFFIC LIGHT BEHIND SEVERAL OTHER CARS. WHEN THE LIGHT CHANGED AND I PRESSED THE ACCELERATOR, THE ENGINE REVVED, BUT THE AUTOMATIC TRANSMISSION DID NOT ENGAGE AND THE CAR WOULD NOT GO FORWARD. IT WOULD GO BACKWARD, BUT NOT FORWARD. A WARNING LIGHT CAME ON FOR A FEW MINUTES THAT SAID THE TRANSMISSION FLUID WAS TOO HOT AND I SHOULD STOP THE CAR SAFELY. (LIKE IT WASN'T ALREADY UTTERLY STOPPED, IN THE MIDDLE OF A LEFT-TURN LANE.) AFTER A FEW MINUTES, THE WARNING LIGHT WENT OFF, BUT THE CAR STILL WOULD NOT GO FORWARD, FIRST INCIDENT OCCURRED AFTER ABOUT 2,400 MILES. THE DEALER SAID THAT HYUNDAI TECHNICAL TOLD HIM THERE WAS AN UPDATE TO THE SENSOR SOFTWARE THAT WOULD FIX THE PROBLEM. HE SAID HE PERFORMED THE UPDATE. SECOND INCIDENT WAS ABOUT A MONTH AND 600 MILES LATER. DIFFERENT TRAFFIC LIGHT, DIFFERENT LEFT TURN LANE, SAME PROBLEM. THIS TIME, AS I WAITED 2 HOURS FOR A TOW TRUCK, AFTER ABOUT 25 MINUTES, THE CAR SPONTANEOUSLY DROPPED BACK INTO GEAR AND I WAS ABLE TO DRIVE IT 2-3 BLOCKS BEFORE IT STOPPED DEAD AGAIN AT ANOTHER TRAFFIC LIGHT. IN THE REMAINING 90 MINUTES WHILE I WAITED FOR THE TOW TRUCK, THE CAR WOULD SPORADICALLY BE ABLE TO LURCH FORWARD A FEW FEET IN LOW GEAR BEFORE DROPPING OUT OF GEAR AGAIN AND STOPPING. THE TOW TRUCK DRIVER WHO TRIED TO DRIVE THE CAR UP THE TRUCK RAMP EXPERIENCED THE SAME PROBLEM AND VERIFIED IT. CAR HAS BEEN AT THE DEALER NOW FOR OVER A WEEK. TODAY, HYUNDAI TECHNICAL GAVE IT A "FAST TRACK" NUMBER. SERVICE MANAGER IS STILL WAITING FOR DIRECTION FROM HYUNDAI TECHNICAL FOR WHAT TO DO TO FIX IT. HE TOLD ME THAT MY CAR IS NOT THE FIRST CAR HE HAS SEEN WITH THIS PROBLEM. AND WHILE MY CAR HAS BEEN IN HIS SHOP THIS WEEK, ANOTHER VEHICLE HAS COME IN WITH THE SAME PROBLEM.

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.
