THIS IS A LOW-MILEAGE HYUNDAI AWD SANTA FE LIMITED WITH 19" ALLOW RIMS. AT ABOUT 11,500 MILES I NOTICED GREASE ON THE INSIDE OF THE FRONT-LEFT WHEEL. IT WAS THICK AND GREEN IN COLOR, THE GREASE USED TO LUBRICATE THE AXLE JOINT. THE CENTRIFUGAL FORCE FROM THE AXLE SPRAYED THE GREASE ALONG THE INSIDE OF THE WHEEL. I CHECKED THE CV BOOT AND AXLE AND IT APPEARED THE GREASE WAS LEAKING FROM THE SEAL BETWEEN THE BOOT AND THE AXLE HUB. THERE WAS A VERY SLIGHT LEAKAGE COMING FROM THE RIGHT WHEEL AXLE AS WELL. THIS SHOULD NOT HAPPEN WITH A VEHICLE ONLY A YEAR OLD. I TOOK IT TO THE HYUNDAI DEALERSHIP AND THEY CONFIRMED THE LEAKAGE ON BOTH WHEELS AND ORDERED TWO AXLE SEAL KITS, WHICH WILL INCLUDE REPLACEMENT OF THE JOINT. THERE WAS NO CHARGE FOR THE INSPECTION AND THERE WILL BE NO CHARGE FOR THE REPAIR. IF THIS WENT UNNOTICED IT COULD CAUSE AN AXLE TO OVERHEAT AND FAIL. AT HIGH SPEEDS THIS COULD CAUSE AN ACCIDENT.

I HAVE A 2010 SANTA FE WITH 19K MILES.....TWICE THIS WEEK I WAS DRIVING AND SUDDENLY THE GAS PEDAL STOPPED WORKING AND ENGINE LIGHT CAME ON. BRAKES WORKED, THANK GOODNESS. ANYONE ELSE HAVE "SUDDEN UNINTENDED DECELERATION"?? AFTER THE FIRST EVENT, I HAD IT TOWED TO THE DEALER (FOLLOWING PROTOCOL IN THE MANUAL). THEY REPORTED A NEW RECALL (IT HAD BEEN SERVICED A FEW MONTHS AGO), EXECUTED A COMPUTER UPDATE AND ALL WAS FIXED (OR SO I THOUGHT). 4 DAYS LATER, WITH LESS THAN 100 MILES DRIVEN SINCE THE REPAIR, IT HAPPENED AGAIN. THIS TIME I WAS IN 35MPH TRAFFIC SO WHEN THE ACCELERATOR PEDAL NO LONGER WORKED, I ALMOST WAS REAR-ENDED. I WAS ABLE TO COAST OUT OF TRAFFIC (BRAKES AND STEERING FINE)TO A SIDE STREET. I WAS ABLE TO COAST HOME (.5 MILE OR SO). CAR WOULD ACCELERATE AFTER STOP SIGNS, ALTHOUGH THE GAS PEDAL DOESN'T RESPOND AT ALL. VERY SCARY THAT IT EVEN SHIFTED TO A HIGHER GEAR AND WOULD GO 30MPH AND KEEP ACCELERATING IF I DIDN'T BRAKE! THE FIRST REPAIR INFO: 1. SPRING PROTECTOR INSTALL (TSB#11-01-021); CAUSE: CAMP 2.TC7 CM ECM UPDATE P0111 10-01-034; CAUSE: CAMP *TT

THE WEEKEND WE PURCHASED OUR 2010 HYUNDAI SANTA FE LIMITED, V6, WHILE DRIVING IN AREA WITH MODERATE GRADES VEHICLE HAD TROUBLE SHIFTING BETWEEN 1ST & 2ND GEARS, 2ND & 3RD GEARS. WE THOUGHT IT COULD BE THE AREA WE WERE DRIVING IN, SO WE CONTINUED TO DRIVE IT TO SEE IF THAT WAS IT. IT WAS NOT. HARD SHIFTING HAS CONTINUED FOR THE COMPLETE EXTENT OF OUR OWNERSHIP COMMENCING AT THE START. ON 12/7/2010, TOOK THE VEHICLE IN TO BE CHECKED, CAUSE: FOUND TRANSMISSION JERKING. MODULE ASSY-AUTO TRANS CONTROL RE, RESET ADAPTIVE TRANS VALUES. RECALL, P0111, ECM UPDATE, PERFORMED CAMP TC7. BRING BACK IF CONTINUES AFTER A COUPLE WEEKS. IT DID CONTINUE, BUT I AM A BUSY PERSON. ON 4/21/2011, RETURNED AGAIN STATING THAT VEHICLE WAS CONTINUING TO SHIFT HARD, JERKING. DEALER SVC STATES COULD NOT DUPLICATE. VEHICLE DUPLICATED FOR ME ON WAY HOME FROM SVC APPT. ON 6/10/11, RETURNED AGAIN FOR SAME PROBLEM WITH HARD SHIFTING AT LOW SPEEDS, JERKING. CAUSE: TCM UPGRADE, RE-RESET ADAPTIVE TRANS VALUES, AFTER WHICH SVC DEPT SAID COULD NOT DUPLICATE AGAIN. SVC MGR STATES THAT A NEW REFLASH HAD BEEN ISSUED SINCE THEY UPGRADED IT LAST ON 12/7/2010. THRU RESEARCH I FIND NO NEW UPGRADE HAS BEEN RELEASED ON SVC MESSAGES/NOTIFICATIONS. I BELIEVE I'VE BEEN MISLEAD. I AM POSITIVE THAT THE VEHICLE WILL DO THIS AGAIN. ALSO, INTERMITTENTLY WHEN ONLY CRANKING THE VEHICLE AND BEFORE THE VEHICLE IS PUT IN GEAR IT WILL IMMEDIATELY HAVE A FEELING OF A LARGE "BANG OR SLAM" AND THEN LUNGE FORWARD EVEN THOUGH STILL IN PARK. THE VEHICLE ALSO MAKES "POPPING" SOUNDS WHEN IN PARK KIND OF LIKE SMALL "BACKFIRES". I HAVE ALSO ASKED THEM TO INVESTIGATE THIS AND DID NOT GET A SATISFACTORY RESPONSE. THEY STATE THAT ALL OF THESE SYMPTOMS ARE CONNECTED TO THE "NEW REFLASH" THAT HAS COME OUT SINCE THE 12/7/2010 SVC APPT. IT "SHOULD" FIX IT. I SAY RECALL IT.

I PURCHASED THE 2010 HYUNDAI SANTA FE NEW WITH ONLY 60 MILES ON IT IN JUNE 2010. IN JANUARY 2011 WE BEGAN SMELLING A FUEL SMELL. THIS OCCURRED ONLY AFTER THE CAR WAS RUNNING AND SHUT OFF THEN SUBSEQUENTLY TURNED BACK ON LESS THAN AN HOUR LATER LIKE WHEN RUNNING ERRANDS. I NEVER SMELLED GAS IF THE CAR SAT OVERNIGHT. WE ALSO WOULD EXPERIENCE AN INTERMITTENT LONG CRANK. I BROUGHT THE CAR TO THE DEALER IN JANUARY 2011 AND THEY REPLACED 2 O-RINGS THAT THEY STATED WERE LEAKING AND FOUND FUEL AROUND. AFTER THESE WERE REPLACED, I STILL HAD THE SAME PROBLEMS. I BROUGHT THE CAR BACK IN FEBRUARY 2011 AND NO KNOWN PROBLEMS WERE FOUND BY THE DEALER. AGAIN, I BROUGHT THE CAR BACK IN MARCH. THIS TIME THEY FOUND FUEL IN THE CHARCOAL CANISTER. THEY STATED I WAS OVERFILLING THE TANK WHICH WAS WHY THERE WAS FUEL IN THE CHARCOAL CANISTER. AFTER SPEAKING WITH THE MANAGER, THEY AGREED TO COVER THE PART AND LABOR AT NO CHARGE AND REPLACED THE CHARCOAL CANISTER. AFTER THIS WAS REPLACED, I NO LONGER EXPERIENCED THE LONG CRANK BUT I STILL SMELL GAS AFTER RUNNING ERRANDS. HYUNDAI WILL AGAIN BE LOOKING AT THE CAR FOR ANY OTHER PROBLEMS, BUT THE DEALER IS REALLY STUMPED SO FAR ON THIS. *TR

GAS/FUEL SMELL COMING FROM ENGINE COMPARTMENT INTO CABIN OF 2010 HYUNDAI SANTA FE GLS (2.4 L AUTOMATIC). SMELL IS NOT NOTICEABLE AT COLD START OVERNIGHT, OR AFTER A COUPLE OF HOURS OF SITTING. SMELL IS VERY NOTICEABLE AFTER THE VEHICLE IS DRIVEN TO OPERATING TEMPERATURE AND THEN SHUT OFF FOR ANYWHERE FROM 10 MINUTES TO AN HOUR. THE FUEL SMELL COMES DIRECTLY INTO THE CABIN WHEN THE HVAC SYSTEM IS SET TO VENT, BUT NOT ON RECIRCULATE. DEALER HAS REMOVED AND REPLACED FUEL INJECTORS AND FUEL RAIL. SMELL STILL PERSISTS. THIS IS A DAILY OCCURRENCE. THE SMELL ALSO OCCURS WHEN STOPPED FOR ANY AMOUNT OF TIME WHILE DRIVING/IDLING. THE SMELL OCCURS WHEN THE VEHICLE'S ENGINE IS OFF, BUT THE KEY IS TURNED TO THE POINT THE HVAC WILL TURN ON. THIS MEANS THE SMELL OCCURS REGARDLESS OF WHETHER THE ENGINE IS RUNNING OR NOT. THE SMELL ACCUMULATES UNDER THE HOOD AND IS STRONGEST NEAR THE PASSENGER SIDE MIDDLE. THE SMELL IS BAD ENOUGH TO PERMEATE CLOTHES WHILE DRIVING AND TO BE SMELLED INSIDE THE HOUSE WHEN THE DOOR TO THE GARAGE IS OPENED. IT'S BAD ENOUGH TO FORCE PARKING THE VEHICLE OUTDOORS. IT APPEARS THIS ISSUE IS BEING DISCUSSED ON THE HYUNDAI FORUMS WEBSITE AND MOST COMPLAINTS ARE FOR THE HYUNDAI SONATA AND SONATA TURBO, BUT THE DESCRIPTION OF THE ISSUE AND POTENTIAL SOLUTIONS POINT TO THE SAME CAUSE FOR MY SANTA FE. THE DEALER HAS ACKNOWLEDGED THE SMELL, BUT NOT IN WRITING. THE VEHICLE HAS BEEN IN FIVE TIMES FOR THIS COMPLAINT - TWICE WITH WORK DONE, TWICE WITH NO WORK DONE (CLAIM WAS COULD NOT REPLICATE), AND ONCE I WAS SENT HOME BEFORE ANY WORK WAS DONE AS THE SERVICE REPRESENTATIVE DETERMINED THERE WAS NOTHING THEY COULD DO AT THAT TIME. THERE APPEARS TO BE NO KNOWN SOLUTION TO THIS ISSUE COMING FORTH FROM HYUNDAI AT THIS TIME. *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.

THE INTERMEDIATE SHAFT MAY SUFFER FROM NOISE AND EXCESSIVE WEAR DUE TO A MISALIGNMENT OF THE INTERMEDIATE SHAFT WITH THE RIGHT SIDE OUTPUT GEAR. CONTINUING TO DRIVE THE VEHICLE IN THIS CONDITION LEADS TO THE DEVELOPMENT OF A WHIRRING/WHINING NOISE AND CAN EVENTUALLY CAUSE DAMAGE TO THE AUTOMATIC TRANSMISSION.

Consequence & remedy

Consequence: DAMAGE TO THE TRANSMISSION MAY CAUSE LOSS OF MOTIVE POWER, INCREASING THE RISK OF A CRASH.

Remedy: DEALERS WILL REPLACE THE RIGHT SIDE OUTPUT GEAR AND INTERMEDIATE SHAFT FREE OF CHARGE. THE SAFETY RECALL IS EXPECTED TO BEGIN DURING JUNE 2011. OWNERS MAY CONTACT HYUNDAI'S CUSTOMER ASSISTANCE CENTER AT 1-800-633-5151.

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.
