MY ENGINE LOST POWER AND STARTED TO KNOCK. CONTACTED HYUNDAI USA TO BE TOLD TO BRING MY CAR IN FOR A DIAGNOSIS. I HAD MY CAR TOWED TO THE DEALERSHIP(ADVANTAGE HYUNDAI). THEY CALLED TO TELL ME "WHY IS MY CAR THERE"?? IN UTTER SHOCK I MENTIONED THAT I HAD CALLED THE DEALERSHIP TO ARRANGE FOR ARRIVAL AND HAVE IT DIAGNOSED. THEN WAS MENTIONED A FEE, WHICH WASN'T MENTIONED FROM ANYONE PRIOR TO HAVING MY CAR TOWED. I HAD UPDATED MY REF # FROM HYUNDAI USA ONLY TO SPEAK WITH SOMEONE TELLING ME THAT BECAUSE THE CAR IS OUT OF WARRANTY HE CANT HELP. WHY DID IT TAKE OPENING A CASE WITH HYUNDAI, UPDATING THE CASE WITH INFO, HAVING MY CAR TOWED TO THE DEALERSHIP(SUGGESTED BY HYUNDAI USA) TO BE TOLD THERE NOTHING THEY CAN DO?? MY CAR IS IN GREAT SHAPE WITH 81K. WHY ARE THESE ENGINES FAILING?? AND WHY ARE THE CONSUMERS VICTIMS TO INFERIOR PRODUCT?? BTW HYUNDAI CONSUMER AFFAIRS DON"T HELP THE CONSUMER. IT'S MORE OF HYUNDAI EXPLAINING THERE WARRANTY.

ON 10/20/20, LEAVING THE PARKING GARAGE AT MY PLACE OF EMPLOYMENT I THOUGHT I HEARD A NOISE COMING FROM THE VEHICLE, BUT AS I ROLLED DOWN THE WINDOW TO LISTEN, I DIDN'T HEAR ANYTHING. I CHECKED THE DASH FOR WARNING LIGHTS; THERE WERE NONE. THE TEMPERATURE WAS ALSO NORMAL, SO I CONTINUED HOME. ABOUT 10 MIN. LATER, DRIVING SOUTH ON I-5 WHILE IN THE FAR LEFT LANE AT 70 MPH, MY 2013 HYUNDAI TUCSON LIMITED EXPERIENCED A MAJOR ENGINE FAILURE, MANIFESTING WITH A TERRIBLE METAL CRASHING SOUND AND SHAKING. I HAD TO IMMEDIATELY CROSS TWO LANES OF HEAVY TRAFFIC, HAZARDS FLASH, TAKING THE EXIT THAT WAS FORTUNATELY RIGHT THERE ON THE IMMEDIATE RIGHT. I WOULD NOT HAVE MADE IT TO THE NEXT EXIT 1 MILE AWAY. BY THE TIME I REACHED THE END OF THE RAMP AND PULLED INTO THE EMERGENCY PARKING, THE ENGINE WAS BARELY SPUTTERING, THE CAR BARELY ROLLING. NEXT DAY, UPON INSPECTION BY THE DEALER, THEY SAID METAL DEBRIS WAS FOUND IN THE ENGINE, SAME BEARING ISSUE AS THE OTHER ENGINE FAILURES THAT WERE RECALLED EARLIER (SANTA FE MODELS, SONATAS, ELANTRAS, AND OTHER TUCSONS). MY MODEL AND TRIM PACKAGE ISN'T PART OF THE RECALL YET. ONE MONTH PRIOR, THE DEALER HAD DONE A SAFETY INSPECTION AND $1,000 OF WORK REPLACING THE DRIVE BELT, HOSES, AND THERMOSTAT GASKET SO THAT I WOULDN'T LOSE THE ENGINE, AS I WAS TOLD BACK THEN. SINCE I STILL LOST THE ENGINE ONLY ONE MONTH LATER AND WITHOUT ANY WARNING AND BECAUSE MY MILEAGE WAS OVER WARRANTY AT APPROX134K, THE DEALERSHIP SUBMITTED A REQUEST TO HYUNDAI FOR GOODWILL AND RENTAL CAR ASSISTANCE ON MY BEHALF. THE MANUFACTURER AGREED TO PAY 75% AND PROVIDE RENTAL CAR ASSISTANCE IF PARTS WERE ON NATIONAL BACK ORDER. IT WAS 3 WEEKS TO ORDER PARTS AND COMPLETE REPAIRS. NO RENTAL CAR ASSISTANCE. I PICK UP THE CAR TODAY. MY PORTION OF THE COST IS MORE THAN $2200. IF THE 2013 TUCSON LIMITED IS ADDED TO THE RECALL LIST, WILL I BE ELIGIBLE FOR REIMBURSEMENT?

I WAS DRIVING ON I-75 IN BROWARD COUNTY AND I DECIDED TO PASS A VEHICLE IN FRONT OF ME, WHEN I ACCELERATED, THE CAR MADE A VERY STRANGE SOUND AND STARTED TO LOOSE POWER... IT STARTED TO SLOWING DOWN BY IT SELF, SO I DECIDED TO GET OUT FROM I-75, LUCKILY WE WERE CLOSE TO ONE REST AREA WHERE WE COULD PARK AND CALL SOMEONE FOR HELP. BEFORE CALLING ANYONE, WE TRY EVERYTHING ON THE CAR. MY BROTHER-IN-LAW CHECKED THE BATTERY, WHICH WAS GOOD, THE ELECTRICAL WAS WORKING FINE FOR FEW MORE MINUTES AND STARTED TO SHUT DOWN SLOWLY. EVERYBODY SAID THAT WAS VERY STRANGE...THEY SAID MY CAR WAS NOT SUPPOSE TO BE IN THAT SITUATION. IT IS WITH 70,000 MILES, IN AN EXCELLENT CONDITION AND THE MAINTENANCE IS UP TO DATE. I CALLED THE TOWING TRUCK FOR PICK UP AND PARKED IT ON MY COUSIN DRIVEWAY WHERE IS TILL TODAY. NOW, I DON'T KNOW WHAT TO DO. IT WILL BE EXPENSIVE TO FIX IT, AND I DON'T HAVE THE MONEY. I DIDN'T RECEIVED ANY RECALL FOR "ENGINE FAILURE" ON THIS SPECIFIC CAR, ALL THOUGH I FOUND ON THE INTERNET A LOT OF COMPLAINTS WITH THE SAME PROBLEM ON SAME YEAR AND MODEL.

ALL OF A SUDDEN THERE WAS A CONSISTANT KNOCKING SOUND EVEN MORE INTENSE THAN THE ONES I HAD HEARD OVER THE YEARS SINCE BUYING THE CAR.THE FRONT OF THE CAR WAS SHACKING AND LOOSING POWER! MY HUSBAND WAS DRIVING IN THE LEFT LANE AND STRUGGLED TO GET IT TO THE SHOULDER WHERE THE ENGINE STILL MAKING THE LOUD KNOCKING SOUND COMPLETELY SHUT DOWN.THERE WAS A TRACTOR TRAILOR BEHIND US WHEN WE GOT TO THE RIGHT LANE AND IF IT HAD DIED THEN WE WOULD HAVE BEEN KILLED! STANDED FOR 40 MINUTES IN A DANGEROUS LOCATION! IT WAS TOWED TO A HYUNDAI DEALER IN HAGERSTOWN MD. WHEN THEY TRIED TO TURN IT ON THERE WAS SMOKE AND THEY WERE QUICK TO PREVENT IT FROM CATCHING FIRE. WE WERE TOLD IT EXPLODED, A BEARING BROKE OFF HIT THE PISTON CREATING A HOLE IN THE ENGINE AND THERE WERE METAL SHAVINGS IN OIL PAN. WE ARE THE ORIG OWNERS AND HAVE KEPT UP MAINTENANCE AT OUR DEALERSHIP, IT HAS 108K MILES ON IT, A COMPREHENSIVE EXT WARRENTEE BUT THEY WILL ONLY PUT IN A 77K MILES USED ENGINE.COULD HAVE THE SAME ISSUES AND MAY NOT BE SAFE.

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.
