Driving approximately 70-75mph on highway with cruise control set. Car starts to make rattling sound & engine warning light goes on, car struggles to accelerate and hovers around 60mph. Upon inspection of engine oil in car, fresh oil has been burned up quickly! Added 1 quart. Drove 45mins at 70-75mph. Notice Engine light on again. Check engine oil. Had quickly burned through 1qt! Add new quart of oil. Let car rest overnight. Driving 70mph without use of cruise control. Then use cruise control. After a bit car engine sounds of rattling & struggling to accelerate. RPM gauge seen going up & down. Through rear view mirror I see lots of bluish smoke. Pull over to let engine rest. Check oil = still 3/4. Use engine dectection device. Indicates that cylinders 3 &4 misfiring. Reset car warning indicator with my detection device. Finish drive going 60mph to arrive at destination without car engine warning going back on.

ON MONDAY, JULY 14, 2014, MY WIFE RODE HER SANTA FE ON A STRAIGHT ROAD ACCELERATING SLIGHTLY UPHILL WHEN THE ENGINE STALLED. ON THURS. DEC. 5, 2013, I HAD A SIMILAR EXPERIENCE, WHICH I REPORTED TO YOU AT THE TIME. THIS IS THE SECOND TIME THIS HAS HAPPENED WITH THIS CAR. AGAIN NOBODY TOUCHED THE IGNITION KEY WHICH HAS NOTHING HANGING ON IT EXCEPT THE ALARM AND DOOR LOCK DONGLE. MY WIFE ALSO SUDDENLY LOST POWER STEERING AND POWER BRAKES, AND LUCKILY THERE WAS NO OTHER TRAFFIC, WHICH COULD HAVE CAUSED AN ACCIDENT. SHE WAS ABLE TO BRING THE CAR TO A SAFE STOP AND THEN WAS ABLE TO RESTART THE ENGINE AND CONTINUE HER TRIP. THE 2010 CAR HAD A FULL TANK OF GAS AND HAS ABOUT 50000 MILES ON THE ODOMETER. IT'S AWD AND HAS A 6 CYL. ENGINE. COULD THIS BE RELATED TO THE IGNITION SWITCH PROBLEM THAT HAS PLAGUED SO MANY GM CARS? NEEDLESS TO SAY WE ARE WORRIED DRIVING THE CAR BECAUSE IF THIS INCIDENT OCCURS AT HIGH SPEED, A SERIOUS ACCIDENT COULD BE THE RESULT. DO YOU KNOW OF ANY SIMILAR EXPERIENCE? WHAT DO YOU ADVISE?

AFTER COMING TO A FULL STOP AT AN INTERSECTION, I ACCELERATED TO ENTER THE INTERSECTION AND TURN RIGHT. ALMOST IMMEDIATELY AS I PULLED INTO THE INTERSECTION, THE CAR STALLED AS THOUGH IT HAD DIED. I CONTINUED TO PRESS ON THE ACCELERATOR AND AFTER 3 TO 4 SECONDS, THE CAR LURCHED FORWARD, WITH FUEL FEED WORKING NORMALLY. I TOOK THE CAR TO MY LOCAL DEALER WHERE I BOUGHT THE CAR FOR INSPECTION. THEY TOOK THE CAR IN FOR TESTING AND SAID THEY COULD NOT FIND ANYTHING WRONG. THIS PROBLEM PERSISTED, WITH THE INCIDENTS BEING INFREQUENT. I REPORTED THIS PROBLEM EACH OF THE NEXT FEW TIMES THE PROBLEM RECURRED. EACH TIME I ASKED IF OTHERS HAD REPORTED THE SAME PROBLEM. EACH TIME I WAS TOLD THERE WERE NO SUCH COMPLAINTS, AND THAT THEY COULD NOT FIND A REASON FOR MY PROBLEM. FINALLY, I LEFT THE VEHICLE AT THE DEALER FOR SEVERAL DAYS WITH THE UNDERSTANDING THAT THEY WOULD DRIVE THE CAR FREQUENTLY, TRYING TO DUPLICATE MY PROBLEM. AFTER SEVERAL DAYS, THEY CALLED TO SAY THEY HAD EXPERIENCED THE PROBLEM AS I HAD REPORTED IT, AND THEY HAD FIXED IT. I ASKED WHAT WAS DONE, AND THE AGENT COULD/WOULD NOT SPECIFY WHAT THE CAUSE WAS, BUT THEY WROTE ON THE INVOICE THAT THEY HAD REPROGRAMMED TCM WITH TSB#11-AT-011-1. I THEN AGAIN QUERIED ABOUT OTHER COMPLAINTS, AND HE SAID THAT THERE HAD BEEN OTHER COMPLAINTS AFTER ALL, AND THIS SHOULD FIX THE PROBLEM. HOWEVER, I HAVE SINCE EXPERIENCED THE PROBLEM AGAIN AND FEAR THAT AN ACCIDENT IS POSSIBLE. THE LATEST: THEY ARE TAKING MY VEHICLE IN THIS THURSDAY FOR A MAJOR DIAGNOSIS "TO TRY TO FIND THE PROBLEM"., AGAIN. *TR

I HAD JUST PULLED INTO THE DRIVEWAY OF A HOUSE I OWN THAT I RENT; I WAS THERE TO MEET MY TENANTS TO DISCUSS A COUPLE OF REPAIRS THAT NEEDED TO BE DONE IN THE HOUSE. I WAS SLOWING THE CAR WITH MY FOOT ON THE BRAKE AS I APPROACHED THE END OF THE DRIVEWAY BY THE SIDE DOOR OF THE HOUSE. THEN I HEARD A SUDDEN, EXTREMELY LOUD ENGINE NOISE THAT SOUNDED LIKE THE ENGINE REVVING VERY FAST AND THE CAR SUDDENLY ACCELERATED. I WAS PROPELLED FORWARD ABOUT 50 FEET INTO THE BACK YARD AND CRASHED INTO SOME LILAC BUSHES DIRECTLY AHEAD OF ME AND INTO THE STEEP DIRT BANK BEHIND THE BUSHES, WHICH STOPPED THE CAR. THERE IS NO GARAGE AND THE DRIVEWAY ENDS WHERE THE LAWN BEGINS. THE FRONT END OF THE CAR IS QUITE DAMAGED AND THE VEHICLE IS PRESENTLY IN THE DEALER'S REPAIR GARAGE. ON THE INTERNET, MY SON FOUND MANY REPORTS OF INCIDENTS OF SUDDEN ACCELERATION FOR THE HYUNDAI SANTA FE FOR MY MODEL YEAR AND FOR OTHER RECENT YEARS AND HE SUGGESTED I FILE THIS REPORT WITH THE NHTSA. *TR

Official recalls

13V113000 · Exterior Lighting:brake Lights:switch

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.

DP21003 · Throttle Control System Vulnerabilities

Opened Nov 12, 2021 · Closed Jun 20, 2023

Status: closed (inferred from source dates) · Vehicle Speed Control:throttle

The Office of Defects Investigation (ODI) of the National Highway Traffic Safety Administration (NHTSA) received a petition letter dated October 10, 2021, requesting an investigation of possible defects in the electronic throttle control (ETC) system on certain Kia vehicles resulting in the opening of DP21-003. Accordingly, Model Year (MY) 2005-2016 Kia Optima/K5, MY 2006-2015 Kia Sorento, MY 2007-2016 Hyundai Elantra, MY 2007-2016 Hyundai Santa Fe, MY 2006-2015 Hyundai Sonatas are all part of the subject population. The petition was originally filed as a Vehicle Owner Questionnaire that can be reviewed at NHTSA.gov under reference (ODI) number 11439675.On November 12, 2021, ODI opened Defect Petition DP21-003 to evaluate the petitioner?s request. ODI performed trend analyses of the VOQs related to vehicle speed control issues for all the subject vehicles and found that none of the 52 Model/Model Year Hyundai/Kia vehicles demonstrated any actionable trend that warranted an investigation.Petitioners submitted 1119 VOQs and non-VOQ cases in which sudden uncommanded acceleration (SUA) or loss of motive power (LOMP) incidents were alleged.For the 1119 reports, 220 were incidents involving crashes, from which 69 subject Hyundai-Kia vehicles were inspected by Hyundai/Kia dealer technicians, Hyundai/Kia engineers, and/or third-party representatives.ODI found the inspections identified no vehicle defects related to the ETC system.Of the 220 crash-involved reports, 13 Event Data Recorder (EDR) records were downloaded successfully and 11 of those indicated driver error: (i.e.) pedal misapplication.A condition where the accelerator pedal is mistakenly applied instead of the brake pedal when the driver wants to stop the vehicle.In addition, ODI reviewed a scientific journal paper published in Forensic Science International in 2016 by Mr. Park et al ., as well as related test videos. ODI does not believe there is any evidence of uncontrollable SUA occurrences in any of the tests reviewed. NHTSA's Office of Vehicle Safety Compliance (OVSC) reviewed the allegations regarding the potential noncompliance with Federal Motor Vehicle Safety Standard No. 124.Based on the information provided, the Agency concludes there is insufficient information for us to determine if a possible non-compliance exists.Finally, both Hyundai and Kia informed ODI that all their vehicles manufactured after 2012 were equipped with an ETC management system, in which the engine speed will go to idle when the system sees signals from both the brake pedal and accelerator pedal at the same time; this is commonly known as the brake-throttle override system.After thoroughly assessing the material submitted by the petitioner, information already in NHTSA's possession, information submitted by Hyundai and Kia in response to an Information Request letter, and the potential risks to safety implicated by the petitioner's allegation, NHTSA does not believe that a formal investigation is warranted. After full consideration of appropriate factors, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA?s reasons for denial of the petition will be published.

PE11010 · Transmission Intermediate Driveshaft

Opened Apr 7, 2011 · Closed May 10, 2011

Status: closed (inferred from source dates) · Power Train:automatic Transmission; Power Train:driveline:driveshaft

On April 25, 2011, Kia Motors Corporation submitted a defect notification letter to NHTSA regarding a transmission intermediate driveshaft condition in approximately 12,690 model year (MY) 2011 Kia Sorento 2-wheel drive vehicles equipped with automatic transmissions and 2.4L engines (NHTSA Recall No. 11V-258).The recall addresses a defect with the external shape of the engine block which can prevent the intermediate shaft bearing bracket from mating evenly with the engine block.This can cause a misalignment of the intermediate shaft with the right side output gear.Resulting damage could cause a loss of motive power.Additionally, on April 27, 2011, Hyundai Motor Company submitted a defect notification (NHTSA Recall No. 11V-261) for the same issue in approximately 6,169 MY 2010 Sante Fe 2-wheel drive vehicles equipped with automatic transmissions and 2.4L engines that use the same components as the recalled Kia Sorento vehicles.This investigation is closed.
