2009 Hyundai Santa Fe Electrical System Problems

[XXX] We took out Stanta Fe to the Hyundia Dealership in Columbia, TN 38401. The installed a new rover cover gasket left and service kit. The purpose was to stop oil from leaking into the alternator. I would like to point out we did not see any visible signs of the gasket was leaking. We had our regular scheduled oil change in Feb of 2025 and no report of an oil leak. We had a service event at the end of June 2025 and were told there was a visible leak was present and appeared to be about 3 months old. We took it back to the dealership and reported the recall issue was occurring. This was 7/25 and just outside of a year. The stated it would not be covered under warranty/recall now. I called and complain to Hyundia corporate. Waited 2 weeks to say it would be taken care of by the dealership. Called them today to arrange for bring the car in but they had no record of what I was told by Hyundia corporate. I believe this breaking faith w the whole recall process with the NTSB. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Alternator failed Due to valve gasket leaking, Hyundai issued a recall during time vehicle was in probate, I did not receive notification and had the valve gasket, manifold gasket, and alternator replaced. In June 30, 2022, When I learned the recall had been issued I filed for reimbursement of repair costs, Approximately $1900. The reimbursement claim was transferred to warrant department. The claim was transferred to claim reimbursement 8/29/2022, I received an email stating it would be 3-4 weeks for reimbursement. I called 9/29 and was informed it would be 120 days from submission date, On 12/6 additional information was needed. I was not notified, and saw the status changed, and called for update on 12/13. I submitted the same day. On 12/22, I received the repayment notification, but not the amount. I called on the phone for 4 hours for amount $727.74 breakdown missing $410 of labor costs.

TWO TIMES MY CAR HAS STALLED WHILE DRIVING, ONE AT 10 MPH AND ONE AT 20 MPH. THERE ARE NO SIGNS THAT THE CAR IS GOING TO STALL. HAVE NO LIGHTS, BRAKES, STEERING, CAN'T EVEN USE HAZARD LIGHTS.

MY 2009 HYUNDAI SANTA FE HAS STALLED MORE THAN 4 TIMES WHILE DRIVING SINCE 2010. IT LOSES POWER WITHOUT WARNING RENDERING THE VEHICLE UNSAFE AND NOT ABLE TO BE DRIVEN. THE FIRST TIME IN 2010 IT STOPPED WHILE ON THE EXIT RAMP OF A HIGHWAY DOING ABOUT 50 MPH. THE CAR WAS BROUGHT TO THE DEALERSHIP AND THEY "COULD NOT DUPLICATE THE PROBLEM" SO THEY DID NOTHING. BROUGHT SAME VEHICLE BACK TO DEALERSHIP IN 2011, 2014 AND 2019. EACH TIME WE ARE TOLD "COULD NOT DUPLICATE AT THIS TIME". THE MOST RECENT ON AUGUST 7, 2019 THEY REPLACED THE ALTERNATOR AND BATTERY COMMENTING THAT "VEHICLE NOW OPERATES NORMALLY. VEHICLE DOES NOT STALL". THE VEHICLE HAS SINCE STALLED AGAIN DURING DRIVING. THE DEALERSHIP WILL ONLY LOOK AGAIN AT THE VEHICLE AT THE COST OF $100.00 PER HOUR. WE HAVE CONTACTED THE CORPORATE OFFICE AND THEY WERE NOT HELPFUL, IN FACT RUDE AND HUNG UP. AFTER READING SO M;ANY COMPLAINTS ON JUST THIS SITE I HOPE OUR GOVERNMENT CAN HELP GET HYUNDAI TO BE RESPONSIBLE FOR THEIR VEHICLES BEFORE SOMEONE GETS HURT OR KILLED.

THE BATTERY LIGHT KEPT BLINKING, MY BATTERY IS NEW, ALSO THE SEAT BELT LIGHT FOR PASSENGER SEAT KEPT BLINKING EVEN WHEN THE SEAT BELT WAS BUCKLED. I STALLED OUT AND WOULDN'T START BACK UP. I WAS IN THE STREET WHEN IT WOULDN'T START BACK UP. I HAD IT LOOKED AT WHEN IT WAS TOWED AND THE SHOP SAID THERE WAS ALOT OF OIL ON MY ALTERNATOR AND I WOULD HAVE TO REPLACE MY VALUE COVER GASKETS ALSO.

I PURCHASED THIS CAR USED IN 2011. OVER THE YEARS, AT RANDOM TIMES, THE RADIO WILL "POP" OFF AND BACK ON AGAIN. IT DOESN'T SEEM TO AFFECT THE REST OF THE ELECTRICAL SYSTEM IN THE CAR, BUT IT'S A LITTLE SCARY WHEN IT HAPPENS - MECHANIC CAN'T REPLICATE. NOW, TWICE IN THE LAST WEEK, MY CAR HAS STALLED WHILE SLOWING DOWN, ONCE ON A MULTI-LANE STREET AND ONCE AFTER DECELERATING COMING OFF THE EXPRESSWAY (COMPLETE LOSS OF POWER, STEERING, BRAKES, ETC). I PUT THE CAR IN NEUTRAL AND IT STARTED RIGHT BACK UP, BUT THIS HAS HAPPENED IN HEAVY TRAFFIC AND SCARED THE CR*P OUT OF ME! I'M TERRIFIED THAT THIS MIGHT HAPPEN AT A HIGHER SPEED ON THE EXPRESSWAY. I HAVE SEEN SEVERAL MENTIONS OF SIMILAR POWER LOSSES FOR THIS SAME VEHICLE. I HAVE NO CHECK ENGINE LIGHTS AND NO CODES COME UP WHEN SCANNED. NO RECALLS REPORTED EITHER, ALTHOUGH A POWER LOSS AT THE WRONG TIME COULD KILL SOMEONE. NOT SURE IF THIS IS ELECTRICAL, ENGINE OR FUEL SYSTEM RELATED - I HAD OVER A HALF A TANK OF GAS IN THE CAR DURING BOTH OCCURRENCES.

AFTER DRIVING AT HIGHWAY SPEEDS AND DECELERATING, HYUNDAI SANTA FE 2009 VEHICLE ABRUPTLY STALLS WITH NO WARNING. NO ERROR CODES SHOW. THIS IS EXTREMELY DANGEROUS AS VEHICLE IMMEDIATELY SHUTS DOWN AND IS AN ACCIDENT RISK. ALL POWER STEERING AND BRAKE OPERATION SHUT DOWN.

RIGHT FRONT FOG LIGHT INOPERATIVE. DEALER REPLACED HALOGEN BULB. WITHIN A FEW DAYS FOG LAMP OVERHEATED CAUSING BULB SOCKET AND LENS BULB HOLDER TO COMPLETELY MELT DOWN CAUSING BULB TO FALL DOWN ONTO THE INSIDE OF THE RIGHT FRONT BUMPER AND BURNED TWO HOLES THROUGH BUMPER ALMOST CAUSING A FIRE AS BULB WAS STILL FUNCTIONING. NO CIRCUIT BREAKERS OR FUSES BLEW. DEALER STATES THIS HAS HAPPENED BEFORE TO OTHER VEHICLES AND NOW DEALER NEEDS TO REPLACE BOTH SOCKET & WIRING AND COMPLETE LENS BODY.

The contact owns a 2009 Hyundai Santa Fe. The contact received a notice for TSB: [XXX] and the vehicle was taken to the dealer where the campaign was completed. The contact stated that while an oil change was being performed, she was informed that the valve cover gasket was leaking. Additionally, the check engine warning light was illuminated. The fuel senders and O rings, the spark plugs, and the valve cover gasket were replaced; however, the failure recurred. The dealer replaced the oil sending unit; however, the failure persisted. The vehicle was taken to an independent mechanic, where the valve cover gasket, the valve cover gasket kit and the spark plugs were replaced. The contact stated that the dealer later replaced the oil pan due to oil leaking. Additionally, the contact stated while attempting to make a left turn from a complete stop, the vehicle chugged and started losing electrical power. The vehicle was towed to the dealer, where the contact was informed that the alternator internally shorted, the vehicle was stuck in drive(D), and the key was stuck in the ignition switch. The battery warning light was illuminated. The dealer performed an unknown repair. The contact stated that she then received a notice for [XXX] and the vehicle was taken to the dealer, where it was diagnosed and determined that the right bank valve cover gasket was fractured, distorted, and was leaking onto the alternator. Additionally, the dealer informed the contact that the left valve cover gasket was leaking; however, the part was not covered. The dealer only replaced the right bank valve cover gasket. The contact stated that the failure persisted. The vehicle was not repaired. The manufacturer was notified of the failure and a case was opened. The failure mileage was approximately 74,936. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). The contact stated there seems to be a defect in the valve covers.

TL* THE CONTACT OWNS A 2009 HYUNDAI SANTA FE. WHILE DRIVING VARIOUS SPEEDS, THE CHECK ENGINE WARNING INDICATOR ILLUMINATED AND THE FUEL GAUGE DISPLAYED AN INCORRECT READING. THE DEALER (HATFIELD HYUNDAI, 1400 AUTO MALL PKWY, COLUMBUS, OH 43228) DIAGNOSED THAT THE FUEL SENDER ASSEMBLY AND FUEL PUMP NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 156,000.

2009 HYUNDAI SANTA FE V6 3.3 LITER HAS EXPERIENCED OCCASIONAL, RANDOM STALLING OVER A FEW YEARS, ALWAYS WHILE BRAKING AND OFTEN WHILE TURNING. THE PROBLEM SEEMS TO HAPPEN AFTER A PERIOD OF STEADY SPEED DRIVING AND THEN SLOWING DOWN AND TURNING. WHEN THIS HAPPENS, THE VEHICLE STEERING INSTANTLY GETS VERY DIFFICULT AND BRAKING ABILITY LIKEWISE BECOMES INCREASINGLY DIFFICULT. AFTER PUTTING THE VEHICLE IN NEUTRAL, OR PULLING OVER AND PARKING THE VEHICLE, IT WILL ALWAYS START RIGHT BACK UP AND RUN FINE. THE THROTTLE POSITION SENSOR HAS BEEN REPLACED BUT THE PROBLEM PERSISTS. I AM A 50 YEAR OLD MAN WHO CAN WRESTLE THE CAR TO SAFETY (SO FAR), BUT MY WIFE, CHILDREN, OR OTHERS MAY NOT BE SO FORTUNATE. THERE ARE REPEATED MENTIONS OF OTHER HYUNDAI VEHICLES WITH SIMILAR PROBLEMS, AND THESE MOSTLY MENTION A TPS REPLACEMENT AND AN ACCOMPANYING ECU FIRMWARE UPDATE. THERE ARE NO APPARENT RECALLS OR TSBS WITH HYUNDAI THAT AFFECT THIS VEHICLE AND ENGINE COMBINATION, AND THIS IS A HUGE SAFETY PROBLEM FOR WHICH THERE APPEARS TO BE A REMEDY PATH.

FOR THE LAST YEAR, MY FUEL GAUGE HAS BEEN MALFUNCTIONING. AT FIRST, IT ONLY HAPPENED EVERY ONCE IN A WHILE, BUT ONCE I GOT TO ABOUT 8 MONTHS, THE GAUGE HAS CONSTANTLY TOLD ME THE WRONG FUEL LEVEL. I HAVE ASKED A MECHANIC ABOUT IT AND IT IS THE FUEL LEVEL SENSORS LOCATED IN THE GAS TANK THAT ARE MALFUNCTIONING. APPARENTLY, THIS IS A PROBLEM WITH MANY OF THE SANTA FE'S THAT WERE BUILT AROUND THAT TIME. I HAVE A LOW MILEAGE VEHICLE. IT WAS BOUGHT IN 2016 WITH 22,000 MILES. THE GAS GAUGE PROBLEM STARTED AROUND 40,000 MILES AND ONLY HAPPENED A FEW TIMES. THE CONSTANT CHECK ENGINE LIGHT ILLUMINATION AND CONSTANT MALFUNCTION OF THE GAS GAUGE STARTED AT 50,000 MILES AND I AM NOW AT 60,000 MILES. THE PROBLEM HAPPENS WHEN THE CAR IS STATIONARY AND WHILE I AM DRIVING IT. I HAVE TO KEEP A FULL TANK AT ALL TIMES JUST DO I DON'T RUN OUT IF GAS.

MY ESC,ABS& AWD SYMBOL CAME ON AT THE SAME TIME & I KNOW OTHER PEOPLE WHO OWN HYUNDAIS & HAD THIS ISSUE IM GUESSING THIS IS SOMETHING MAJOR BECAUSE WHEN I CALLED THE DEALERSHIP THEY KNEW EXACTLY WHAT I WAS TALKING ABOUT THEY ALL CAME ON WHILE I WAS DRIVING

TL* THE CONTACT OWNS A 2009 HYUNDAI SANTA FE. WHILE DRIVING APPROXIMATELY 15 MPH, THERE WAS A LOUD POP SOUND AND THE VEHICLE FAILED TO ACCELERATE. THE CHECK ENGINE WARNING INDICATOR ILLUMINATED. IN ADDITION, THE FUEL GAUGE READ EMPTY. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC, BUT THE FAILURE COULD NOT BE DUPLICATED. THE MANUFACTURER AND THE DEALER WERE NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS UNKNOWN. UPDATED 08/23/17*LJ *CN

GAS GAUGE AND LIGHT ALWAYS ON EMPTY WHEN TIGHT AFTER IT IS FULL OF GAS AND LOUD HUMMING SOUND FROM FUEL PUMP. STALLED OUT IN MIDDLE OF INTERSECTION MULTIPLE TIMES.

TL* THE CONTACT OWNS A 2009 HYUNDAI SANTA FE. THE CONTACT STATED WHILE DRIVING AT VARIOUS SPEEDS, THE HEATER AND AIR CONDITION SPONTANEOUSLY ACTIVATED WITHOUT WARNING AND FAILED TO TURN OFF. THE LOCAL DEALER WAS NOT CONTACTED. THE VEHICLE WAS NOT DIAGNOSED NOR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS APPROXIMATELY 75,000.

MY FUEL GAUGE IS NO LONGER WORKING. IT DOESN'T REGISTER THE AMOUNT OF GAS. THE GAUGE GOES UP AND DOWN RANDOMLY AND MAINLY STAYS ON EMPTY.

FUEL GAUGE NOT WORKING PROPERLY, IT WILL GO FROM SHOWING THERE IS GAS IN THE TANK TO COMPLETELY EMPTY, THEN BACK TO GAS IN THE TANK. THIS HAS LEAD TO THE CHECK ENGINE LIGHT COMING ON. I DON'T WANT TO GET STUCK OUT IN THIS COLD WEATHER WITH AN EMPTY TANK DUE TO A FAULTY FUEL GAUGE

THE CHECK ENGINE LIGHT WENT ON BECAUSE OF THE FUEL GAUGE. IT WAS RUNNING ON A CITY STREET. NOW I CAN'T TELL HOW MUCH GAS I DO, OR DON'T, HAVE

THE CHECK ENGINE LIGHT CAME ON BECAUSE OF THE GAS GAUGE. NOW I HAVE NO CLUE HOW MUCH GAS I HAVE BECAUSE THE READER ON THE DASH KEEPS GOING UP AND DOWN. A MONTH AGO, I HAD THE ALTERNATOR AND GAS LINE REPLACED BECAUSE OF THE LAST RECALL/SERVICE ANNOUNCEMENT. THESE ELECTRICAL PROBLEMS STEM FROM THAT REPLACEMENT.
