ABOUT FOUR MONTHS AFTER WE PURCHASED OUR VEHICLE, IT BEGAN RATTLING WHEN WE WOULD SLOW DOWN TO PARK OR MAKE TURNS. THE BEST WAY I CAN EXPLAIN IS LIKE WHEN A MANUAL TRANSITION IS ABOUT TO SHUT OFF BECAUSE ITS NOT GOING IN TO THE CORRECT GEAR. WE TOOK THE VEHICLE TO THE DEALERSHIP AND THEY TOLD US THAT BECAUSE OF THE DUAL TRANSMISSION, THIS WAS EXPECTED. THEY SAID THAT PUTTING IN ECO OR SPORT MODE THE ISSUE WOULD BE LESS NOTICEABLE. THEY EVEN SHOWED US A VIDEO ABOUT THE DUAL TRANSMISSION THINKING THAT THIS WOULD HELP FIX OUR CAR. WE HAVE RETURNED AT LEAST THREE MORE TIMES WE THE SAME CONCERN AND HAVE BEEN TOLD THERE IS NOTHING WRONG WITH THE CAR SINCE THE COMPUTER DETERMINED NOTHING WAS WRONG. THE BIGGEST CONCERN I HAVE IS THAT THE RATTLING HAS BECOME WORSE AND MORE CONSISTENT AND THAT THE CAR MAY STOP ALL OF A SUDDEN WHEN IM MAKING A TURN OR I CAN CAUSE AN ACCIDENT.

MY HYUNDAI TUCSON TRANSMISSION DOES NOT SHIFT IN A LOGICAL AND PREDICTABLE MANNER, OCCASIONALLY NOT RESPONDING WHEN I NEED ACCELERATION SUCH AS PULLING INTO TRAFFIC AT A JUNCTION. MY WIFE NEARLY HAD A COLLISION WHEN THE TRANSMISSION DID NOT RESPOND CORRECTLY WHEN NEEDED. ADDITIONALLY THE CLUTCH JUDDERS AND SHAKES THE WHOLE VEHICLE WHEN MOVING SLOWLY IN TRAFFIC AND WHEN PULLING AWAY FROM A STOP. IF YOU HAVE READ ANY OF THE 300 OR MORE COMPLAINTS IN THIS SECTION YOU WILL KNOW THAT THERE IS A SERIOUS DESIGN PROBLEM WITH THE TRANSMISSION IN THIS CAR AND IT IS NOT FIXED REGARDLESS OF THE RECALLS OR BULLETINS TO DATE. MOST LIKELY HYUNDAI ARE NOT REPORTING THEIR COMPLAINT LEVELS TO YOU AS THEY SHOULD WHICH KEEPS THE WOLVES FROM THE DOOR, BUT IT DOESN'T TAKE MUCH TIME READING ALL THESE COMPLAINTS TO UNDERSTAND THERE IS A SERIOUS PROBLEM THAT IS UNRESOLVED. THE TRANSMISSION IS ELECTRONICALLY CONTROLLED AND THE SOFTWARE ENGINEERS JUST CANNOT POSSIBLY PREDICT ALL GIVEN DRIVER OR DRIVING CONDITIONS. CONSEQUENTLY ON ALMOST EVERY TRIP IN THIS CAR THERE IS A LATE SHIFT, EARLY SHIFT OR HESITATION THAT WILL OCCUR, SOMETHING THAT IS NOT WHAT I EXPECT OF IT. I HAVE A SHORT UPHILL DRIVEWAY TO MY GARAGE, AND EVERY TIME I PARK ON THE DRIVEWAY I'M NOT SURE IF I'M GOING TO HIT THE GARAGE DOOR OR NOT. I HAVE JUST NO CONFIDENCE IN ITS CONTROL-ABILITY AT ALL. THE RECALL DIDN'T FIX ANYTHING NO MATTER WHAT HYUNDAI TELLS YOU AND NOW 3 YEARS INTO THE MODEL ITS STILL THE SAME. YOU CANNOT TURN A BLIND EYE TO THIS AND HOPE IT GOES AWAY. HYUNDAI IN THE MEANTIME HAS ABANDONED THIS TRANSMISSION FOR '19 ON THE TUCSON AND THEY WANT THE PROBLEM TO DISAPPEAR, BUT THIS IS THEIR WAY OF DEALING WITH IT. PROBLEM WAS ORIGINALLY REPORTED TO HYUNDAI IN APRIL 2016 - ABOUT 6 MONTHS AFTER PURCHASE

MY MECHANIC TELLS ME HIS EVALUATION IS THE VEHICLE'S TURBO UNIT CAUSES THE ENGINE TO RUN VERY HOT, AND THE INTERNAL SEALS ARE BREAKING DOWN, CAUSING OIL TO MIX WITH THE FUEL. THE SOLUTION IS AN ENGINE REBUILD, WHICH WILL COST OVER $3,000. SUCH A REBUILD WILL RESULT IN THE SAME ISSUE ARISING AGAIN AFTER THE VEHICLE IS IN USE FOR A PERIOD OF TIME. THE MANUFACTURER HAS REFUSED TO ADDRESS THE ISSUE, AS I HAVE CORRESPONDED WITH THEM ABOUT IT. THE ISSUE IS GENERIC TO ALL HYUNDAI TUCSONS WITH 1.6 LITRE TURBOCHARGED ENGINE. MY MECHANIC HAS RESEARCHED THE ISSUE, AND SAYS IT OCCURS IN ALL HYUNDAI TUCSON VEHICLES WITH THIS ENGINE CONFIGURATION. THERE ARE OTHER ISSUES RELATED TO BUILD QUALITY, TRANSMISSION, AND OTHER COMPONENTS, BUT THIS ISSUE OF THE DEFECTIVE ENGINE DESIGN IS OBVIOUSLY THE MOST IMPORTANT. THE DEALER THAT SOLD ME THIS VEHICLE KNEW OF THIS CONDITION AND DID NOT DISCLOSE IT AT THE TIME OF SALE, AND REPRESENTED THAT THE ENGINE WAS IN SOUND WORKING ORDER. *DT*JB

I OPENED A CASE WITH HYUNDAI CORPORATE BUT THE CASE IS OPEN AND UNRESOLVED BECAUSE THE PROBLEM IS INTERMITTENT AND ONLY HAPPENS ONCE PER DAY. AN INTERMITTENT PROBLEM IS STILL A SAFETY HAZARD, ESPECIALLY WHEN IT CAUSES THE DRIVER TO LOSE THE ABILITY TO CONTROL THE VEHICLE! IT IS A SAFETY ISSUE THAT COULD DIRECTLY CAUSE AN ACCIDENT. THE NHTSA NEEDS TO BE AWARE OF THIS AND HYUNDAI AND THEIR DEALERSHIPS NEED TO TAKE OWNERSHIP AND MAKE CORRECTIVE ACTIONS BEFORE SOMEONE GETS SERIOUSLY INJURED BY THIS DEFECT. I HAVE A VIDEO OF THE ISSUE OCCURRING THAT I'M HAPPY TO SHARE AS WELL.

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.
