I HAVE ISSUE THAT HYUNDAI RECALLED THE SONATA AND SANTA FE OF THE SAME YEAR AND ALSO KIA RECALLED THE SPORTAGE FOR ENGINE KNOCKING. THE ENGINE IS THE SAME EXACT ENGINE IN THE 2013 HYUNDAI TUSCON BUT IT DOESN'T HAVE A RECALL. THIS MAKE ZERO SENSE.

WHILE DRIVING DOWN THE FREEWAY, MY CAR BEGAN TO SHAKE AND FELT AS THOUGH I HAD A TIRE ISSUE. I SLOWED DOWN, AND THE VIBRATION ESCALATED SO I PULLED OVER. ONCE I WAS AT THE SIDE OF THE ROAD, THE ENGINE STARTED MAKING LOUD KNOCKING NOISES. I CALLED A TOW TRUCK AT THIS POINT AND THE CAR WAS TOWED TO A HYUNDAI DEALERSHIP WHERE IT WAS DETERMINED THAT THE ENGINE HAD BLOWN. I CONTACTED HYUNDAI CONSUMER AFFAIRS AND THEY DID A CASE REVIEW. I WAS TOLD THAT SINCE THE CAR, WHICH IS 5 YRS OLD AND HAS 87,900 MILES, IT IS OUTSIDE OF THE WARRANTY. I QUESTIONED THE RECALL ON OTHER CARS WITH THE THETA II ENGINE SUCH AS THE SANTA FE AND THE SONATA AND WAS INFORMED THAT MY CAR DIDN'T HAVE ENOUGH COMPLAINTS TO BE INCLUDED. APPARENTLY, ALTHOUGH THEY HAVE THE SAME ENGINE, THE TUSCON ENGINE IS SLIGHTLY SMALLER SO DOES NOT QUALIFY FOR THE RECALL. THE SAME ISSUES APPLY WITH THE RECALLED ENGINE THAT MY ENGINE HAS WHICH IS METAL SHAVINGS AROUND THE CRANKSHAFT. THE METAL SHAVINGS HAVE CAUSED INSUFFICIENT MOVEMENT OF OIL THROUGHOUT THE ENGINE.

I AM WRITING IN RESPONSE TO THE RECENT ISSUES I AM HAVING WITH MY 2013 TUCSON. IT IS CURRENTLY SITTING (BECAUSE IT IS UNABLE TO START) AT A HYUNDAI DEALERSHIP. I WAS TOLD FROM HYUNDAI CUSTOMER SERVICE TO HAVE IT TOWED THERE DUE TO THE ENGINE TROUBLE I AM HAVING WITH THE CAR, AND DID SO ON MARCH 16, 2018. I DO NOT FEEL THAT THE COMPLETE ENGINE FAILURE IS DUE TO ANY NEGLIGENCE ON MY PART. I HAVE ALWAYS KEPT UP WITH REGULAR MAINTENANCE ON THE CAR INCLUDING OIL CHANGES. I CHOSE TO PURCHASE A HYUNDAI BECAUSE OF THEIR KNOWN RELIABILITY AND SAFETY. THESE ARE MOST IMPORTANT WHEN CHOOSING A VEHICLE TO OWN, AND I FELT HYNDAI WAS TOP IN BOTH THOSE CATEGORIES. I HAVE TWO YOUNG GIRLS TO KEEP SAFE. HOWEVER HYNDAI HAS PROVEN TO NOT BE. ONE MOMENT I WAS ABLE TO DRIVE MY TUSCON AND THEN THE NEXT MOMENT I AM UNABLE TO START IT AND AM LOOKING AT A COST TO FIX IT AT WELL OVER $5000.00.AUTO NATION HAS LOOKED AT THE CAR AS HAS STATED THAT THERE ARE COMPLICATIONS WITH THE CVVT GEAR AND THE TIMING CHAIN. HENCE THE REASON THE CAR NO LONGER CAN START AND NEEDS TO BE FIXED. I FEEL THAT THE ENGINE PROBLEMS NEED TO BE ADDRESSED AND PAID FOR BY HYUNDAI DUE TO MANUFACTURER'S ERROR. I HAVE TRIED TO FACILITATE THESE ISSUES BY SPEAKING DIRECTLY WITH HYUNDAI CUSTOMER SERVICE. EVERY TIME I HAVE CALLED, I HAVE SPOKEN TO A DIFFERENT CUSTOMER SERVICE REPRESENTATIVE AND GIVEN A DIFFERENT CASE NUMBER. DESPITE EXPLAINING TO A NEW PERSON THE DETAILS OF THE PROCESS I AM GOING THROUGH, EACH REPRESENTATIVES HAS HAD A DIFFERENT EXCUSE AS TO WHAT WILL HAPPEN IN REPAIRING MY CAR. THERE HAS BEEN NO CONSISTENCY ON YOUR END. MY FAMILY AND I HAVE BEEN LOYAL CUSTOMERS OF HYUNDAI FOR YEARS. IN RETURN, I WOULD EXPECT HYUNDAI TO BE AVAILABLE FOR ASSISTANCE IN THIS MATTER.

ON SEPT. 9TH 2017 WE WERE EVACUATING FROM HURRICANE IRMA. WE HEADED NORTH FROM GA. ON I-77 IN N.C ALL THE LIGHTS CAME ON AND CAR SLOWED DOWN. WE PULLED OVER AND SHUT IT OFF. WHEN TURNING IT BACK ON A LOUD HORRIBLE NOISE WAS COMING FROM THE FRONT. WE WERE ABLE TO SLOWLY GET OFF THE EXIT. WE FOUND A MECHANIC SHOP AND TOOK IT THERE TO SEE IF THEY COULD TELL US WHAT IT WAS. THE CAR NEVER GAVE US ANY WARNINGS OR LIGHTS CAME ON PRIOR TO THIS. WHEN WE PURCHASED THE CAR IN 2016, WE HAD TAKEN IT TO THE HYUNDAI DEALER WE BOUGHT IT FROM DUE TO A KNOCKING NOISE COMING FROM THE FRONT. WE TOOK IT ABOUT 3 TIMES AND TO NO AVAIL THEY DIDN'T FIND ANYTHING. WE PURCHASED THE CAR WITH ALMOST 35,000 MILES AND IT WAS AT 78,000 MILES WHEN IT LEFT US STRANDED IN NC. ON MONDAY 9/11/17 THE MECHANIC CALLED US AND TOLD US HE FOUND OIL AND METAL SHAVINGS IN THE PAN AND THAT THE ENGINE HAD FAILED. WE'VE ONLY HAD THIS CAR FOR 1 1/2 YRS. NOW NOT ONLY WE WERE OUT OF POCKET FOR 4 NIGHTS AT A HOTEL, WE HAD TO RENT A UHAUL TO TRANSPORT THE CAR BACK TO GA. FILED A COMPLAINT WITH HYUNDAI ON 9/16/17. THEY GOT BACK TO ME ON 9/28 AND 9/29. I WAS TOLD THE SAVANNAH HYUNDAI DEALER WANTS US TO TOW THE CAR TO THEIR SERVICE DEPT. AT OUR EXPENSE PLUS WE WOULD HAVE TO PAY THEM $400 SO THEY CAN DO A FULL INSPECTION ON OUR CAR. THE SAME CAR I WAS BRINGING TO THEM WITH ISSUES BEFORE WE WERE OUT OF WARRANTY. I AM AWARE OF A LOT OF ISSUES WITH THESE ENGINES AND THEY NEED TO BE RECALLED AND REPLACED.

I RELIGIOUSLY MAINTAINED MAINTENANCE ON MY SUV, BUT OUT THE BLUE, LAST WEEKEND 7/29-30 I WAS AT A LIGHT AND THE CHECK ENGINE LIGHT APPEARED AND SOMETHING BROKE IN THE ENGINE AREA, I HEARD A SNAP, IT SOUNDED LIKE A BELT. WELL, I FLAT BED TOWED THE VEHICLE TO THE DEALERSHIP AND TO MY AMAZEMENT, I RECEIVED A CALL FROM THE SERVICE ADVISOR THAT I NEEDED A NEW ENGINE? THE COST WOULD BE AROUND $8,000.00. I RELIGIOUSLY HAD EVERY WARRANTY SERVICE DONE AND THEY CAME BACK WITH MY CRANK SHANK PINS AND PISTONS WERE WORN OUT AND ROD KNOCKING WAS TAKEN PLACE, PLUS NO MORE ROD BEARINGS. I ASKED WHAT COULD OF CAUSED THIS AND HE STATED, "LACK OF OIL?". I NEVER MISSED AN OIL CHANGE ON THE SUV, SO HOW COULD THIS BE?? ALSO, METAL SHAVINGS WERE FOUND IN THE OIL PAIN AND CYLINDER 2 AND 3 GONE. THERE WAS A RECALL ON THE SANTA FE SUV 2011-2013, KIA 2011-2014 WHEREBY THE SAME THING CRANKPINS, METAL SHAVINGS FOUND, THE EXACT WORDING FROM THE CLASS ACTION LAWSUIT (FOUND ONLINE) IS "DURING MACHINING OF THE ENTIRE ENGINE, CRANKSHAFT AND CRANKPINS, METAL SHAVINGS MAY HAVE BEEN LEFT WITHIN THE CRANKSHAFT OIL PASSAGES, OIL MAY BE BLOCKED AND CAUSE THE CONNECTING RODS TO WEAR, WHICH WOULD THEN CAUSE HEM TO FAIL AND SEIZE THE ENGINE. NOW, THEY DIDN'T LIST MY VEHICLE, BUT IT'S THE EXACT AND SHOULD BE INVESTIGATED SINCE MY VEHICLE HAS THE SAME ENGINE! ALSO, THIS OCCURRED AT EXACTLY 100,000 MILES WHEN THE WARRANTY EXPIRED. NOW, THE SERVICE ADVISORS ARE BEING HORRID AND HEATED EXCHANGES ARE GOING ON WITH THE CAR DEALERSHIP TEAM ON MY CAR REPAIR. IT'S STILL SITTING AT THE DEALERSHIP AND I'M IN AN EXPENSIVE RENTAL. I HAD JUST MADE MY LAST PAYMENT....

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.
