HIGHWAY, BRIDGE, FOLLOWING SIGNIFICANTLY FAR BACK. CAR STOPS AHEAD AND I BRAKE IN PLENTY OF TIME (MY SON WAS IN THE FRONT SEAT AND CAN ATTEST TO THAT). CAR BRAKES BUT VERY SLOWLY, NOT IN TIME SO WE HIT THE STATIONARY CAR AND THEN WE WERE HIT MUCH HARDER FROM BEHIND. AIRBAGS DEPLOYED. THE CAR IMMEDIATELY FILLED WITH SMOKE WHICH I ATTRIBUTED TO THE AIR BAGS BECAUSE I DID NOT KNOW ANY BETTER. VERY SCARED, I SCREAMED FOR THE KIDS TO GET OUT OF THE CAR. SMOKE WAS GONE BY THE TIME POLICE ARRIVED. WE WERE OK, MY SON AND I HAD SORE RIBS AND WHILE TALKING WITH POLICE MY LEFT HAND WAS BURNING FROM SOMETHING. NOTHING WAS VISIBLE SO I SAW KNOW POINT IN TELLING ANYONE. IT LEFT A RASH AND WITHIN TIME IT PEELED AND NOW IS BACK TO NORMAL. A FEW DAYS LATER, HAD SOME HEADACHES. WENT TO THE ATHLETIC TRAINER AT OUR SCHOOL (I AM A TEACHER) AND WAS PUT ON CONCUSSION PROTOCOL. CAR WAS TOTALED. THE FRONT LOOKED LIKE AN ACCORDION AS WE WERE PUSHED SIGNIFICANTLY INTO THE VEHICLE IN FRONT BY THE CAR WHO HIT US FROM BEHIND. I WAS SO RELIEVED THAT EVERYONE WAS OK THAT I REALLY DID NOT THINK ABOUT IT UNTIL RECALL NOTICE CAME FOR THE CAR WHICH OF COURSE WAS ALREADY GONE. ENGINE PROBLEMS WITH "OIL LEAKS AND POSSIBLE SPONTANEOUS FIRES, INCREASING RISK FOR ACCIDENT" IS THE WORDING ON THE RECALL.

TAKATA RECALL : I HAVE TO DRIVE 47 MILES ON A FAST PACED HIGHWAY IN SOUTHERN FLORIDA IN ORDER TO GET TO MY JOB, DAILY. MULTIPLE TIMES A WEEK I EXPERIENCE A STALL WHILE TRAVELING AT HIGH SPEEDS ON THE HIGHWAY. I TOOK MY CAR TO A LOCAL HYUNDAI DEALERSHIP RECENTLY AND THEY DID NOT EVEN KNOW ABOUT THE UPCOMING RECALL. FOR MONTHS, I HAVE BEEN HAVING TO DRIVE MY CAR AND FEEL UNSAFE. I HAVE TO GO TO WORK, AND I DO NOT HAVE ANOTHER VEHICLE OPTION. I FEEL UNSAFE AND AM INCREDIBLY UPSET THAT HYUNDAI HAS NOT FOUND A RESOLUTION YET. IF THIS PROBLEM IS NOT FIXED SOON I WILL BE FORCED TO GET ANOTHER VEHICLE, REGARDLESS OF MY FINANCIAL SITUATION. MY NEXT VEHICLE WILL NOT BE A HYUNDAI, SOLELY BECAUSE OF THE AMOUNT OF TIME THIS RECALL RESOLUTION IS TAKING.

Apr 1, 2013
Hyundai Motor Company (Hyundai) is recalling certain model year 2006-2009 Accent, model year 2007-2011 Azera, Sonata and Sante Fe,2006-2011 Tucson, 2009-2011 Elantra Touring, 2007-2010 Elantra, 2008-2011 Veracruz, 2009-2011 Genesis, 2010-2011 Genesis Coupe, 2007-2008 Entourage, and 2006-2008 Tiburon vehicles. Originally, in April 2013, Hyundai recalled 1,059,824 model year 2007-2009 Accent and Tucson, model year 2007-2010 Elantra, model year 2007-2011 Santa Fe, model year 2008-2009 Veracruz, model year 2010-2011 Genesis Coupe, and model year 2011 Sonata vehicles. In September 2013, Hyundai informed the agency that it was adding more vehicles to this campaign, representing an additional 652,512 units. The total number of vehicles being recalled is now 1,712,336. In the affected vehicles, the stop lamp switch may malfunction. A malfunctioning stop lamp switch may cause the brake lights to not illuminate when the brake pedal is depressed or may cause an inability to deactivate the cruise control by depressing the brake pedal. Additionally, a malfunctioning stop lamp switch may also result in intermittent operation of the push-button start feature, affect the operation of the brake transmission shift interlock feature, preventing the shifter from being moved out of the PARK position and cause the Electronic Stability Control (ESC) malfunction light to illuminate.
Consequence & remedy
Consequence: Failure to illuminate the stop lamps during braking or inability to disengage the cruise control could increase the risk of a crash. Additionally, when the ignition is in the 'ON' position, the transmission shifter may be able to be moved out of Park without first applying the brake. This may lead to unintentional movement of the car which may increase the risk of a crash.
Remedy: Hyundai will notify owners, and dealers will replace the stop lamp switch, free of charge. The safety recall began on April 22, 2013. Owners may contact Hyundai at 1-800-633-5151. Hyundai's recall campaign number is 110.

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.
