THIS VEHICLE HAS DEVELOPED A SPEED SENSITIVE "WHIRRING" SOUND WHILE THE TRANSMISSION IS ENGAGED. WE INITIALLY THOUGHT IT WAS A TIRE NOISE, BUT DID NOT GO AWAY WHEN NEW TIRES WERE INSTALLED. THE DEALERSHIP TOLD US IT WAS THE DRIVE BELT RUBBING AGAINST THE COVER, BUT FURTHER INVESTIGATION BY ANOTHER REPAIR FACILITY FOUND NO EXCESSIVE WEAR ON THE BELT, AND NO INDICATION OF CONTACT WITH THE COVER. THE NOISE IS ACTUALLY COMING FROM THE TRANSMISSION, AND IS EXACTLY AS DESCRIBED IN RECALL 102 WHICH APPLIES TO 2010 MODELS. I PLAN TO START A FIGHT WITH HYUNDAI OVER THIS REPAIR AS THE TRANSMISSIONS ARE THE SAME ON THE 2008 MODELS AS THE 2010.

THE SANTA FE GAS GAUGE BEHAVES ERRATICALLY! AS YOU DRIVE, THE FUEL INDICATOR NEEDLE MOVES UP AND DOWN SO THAT YOU DO NOT KNOW ACCURATELY HOW MUCH FUEL REMAINS IN THE GAS TANK. THE NEEDLE MAY ALSO INDICATE A VERY LOW FUEL LEVEL BY ILLUMINATING THE "LOW FUEL" WARNING LIGHT ON THE DASHBOARD AS WELL. THE PROBLEM APPEARS TO BE GETTING WORSE AS DRIVE TIME GOES ON AS THE NEEDLE MOVEMENTS INCREASE THE LONGER TIME THE SUV IS DRIVEN AND THE VOLUME OF FUEL DECREASES IN THE FUEL TANK. AFTER A PERIOD OF TIME THE CHECK ENGINE LIGHT WILL ALSO ILLUMINATE TO WARN OF A VEHICLE ENGINE / DRIVE-TRAIN PROBLEM. IN MY CASE I HAVE RESET THE CHECK ENGINE MANUALLY AND AFTER A NUMBER OF TRIPS THE CHECK ENGINE LIGHT WILL REAPPEAR. THIS LOW FUEL WARNING CYCLE HAS BEEN REPEATED NUMEROUS TIMES AND MAY CAUSE A DRIVER TO BE DISTRACTED TO SEE THE LOW FUEL WARNING LIGHT, WHEN IN FACT THERE MAY BE SUFFICIENT FUEL IN THE GAS TANK. I FIND THAT THIS PROBLEM IS VERY DISCONCERTING AS YOU DON'T KNOW WHETHER YOU MAY BE RUNNING OUT OF GASOLINE. *JS

THROTTLE ACCELERATED BY ITSELF AND WAS STUCK WIDE OPEN. COULD NOT GET THE THROTTLE TO DISENGAGE. I TRIED TAPPING THE GAS PEDAL SEVERAL TIMES AND THIS DID NOTHING. MANAGED TO HOLD BOTH FEET ON BRAKE AND DOWNSHIFT INTO LOW. I GOT VEHICLE ONTO SHOULDER AND PUT IT IN NEUTRAL AND THE ENGINE CONTINUED TO RUN FULL THROTTLE. I SHOVED IT INTO PARK AND TURNED THE KEY OFF. THE ENGINE DID NOT DISENGAGE UNTIL THE KEY WAS TURNED OFF. VERY BAD FOR TRANSMISSION TO SHOVE IT INTO PARK BUT I HAD NO OTHER OPTIONS. VERY SCARY. I HAVE BEEN TOLD THAT THERE IS NO RECALL. I CALLED HYUNDAI AND FILED A REPORT BUT THEY HAVE NOT CALLED ME BACK YET WITH REPAIR OPTIONS. *TR

2008 HYUNDAI SANTA FE WILL NOT GO OVER 20 MPH. AFTER PRESSING ON THE BRAKES SEVERAL TIMES IT STARTS TO MOVE AGAIN. I TOOK THE VEHICLE TO THE HYUNDAI DEALERSHIP BECAUSE THE CHECK ENGINE LIGHT ALSO CAME DURING THIS ORDEAL. THE DEALERSHIP SAID THEY FIXED THE PROBLEM, BUT IT HAS REAR ITS UGLY HEAD AGAIN. THE CHECK ENGINE LIGHT IS ON AND IT WILL NOT GO OVER 20 MPH. I AM NOT THE ONLY OWNER OF A 2008 HYUNDAI SANTA FE WHO HAS EXPERIENCED THIS PROBLEM. PLEASE CONTACT THE HYUNDAI MANUFACTURER TO SOLVE THIS PROBLEM, BECAUSE IT CAN LEAD TO A SERIOUS TRAFFIC ACCIDENT IF IT'S NOT FIXED. LET'S BE PROACTIVE THIS TIME INSTEAD OF WAITING UNTIL SOMEONE IS IN A FATAL ACCIDENT. *TR

Official recalls
4Apr 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.
Jul 25, 2012
Hyundai is recalling certain model year 2007 through 2009 Santa Fe vehicles manufactured from April 19, 2006, through July 7, 2008. The occupant classification system (OCS) may need recalibration to accurately detect small statured adults.
Consequence & remedy
Consequence: Improper classification or detection may cause the front passenger airbag not to deploy in the event of a crash, increasing the risk of injury to the front passenger.
Remedy: Hyundai will notify owners, and dealers will update the classification software free of charge. The safety recall began on September 7, 2012. Owners may contact Hyundai at 1-800-633-5151.

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.
