2009 Hyundai Santa FE Problems

What owners report

Owners of this model year most often report a misreading fuel gauge that swings between empty and full, which they link to the fuel level sensors and which can lead to running out of fuel. A second common theme is intermittent stalling while driving or decelerating, typically with no warning lights or stored codes. Complaints in the sample cluster between roughly 60,000 and 120,000 miles for the fuel gauge and engine categories, while brake, airbag and unintended-acceleration reports appear at a much wider range of miles.

1. 1
   Fuel system

   Fuel gauge reads wrong / fuel level sensor failure

   • 98 complaints (27%)
   • median 88,000 mi at 7.0 yrs old (88 state mileage)
   • 1 mention a crash, fire or injury
   • owner-quoted repair $550 (median of 18 quotes)
   • filed 2012–2022

   Complaints describe the fuel gauge dropping to empty after a fill-up, then rising again or fluctuating between readings, often with the check engine light on. Several owners say a scan pointed to the fuel level sensor, and some had one or both senders replaced only for the problem to return. Several report they now track mileage or the trip odometer to avoid running out of fuel, and a few describe stalling or running dry with the gauge still showing fuel. Mostly reported between about 60,000 and 120,000 miles, appearing at any time of year.

   What to check: Ask whether the fuel level senders have been replaced and whether the check engine light is currently on; fill the tank during a test drive and confirm the gauge reads full and settles correctly after restarting.

   “Fuel gauge went up and down. Ran out of gas going 70mph on turnpike it was harrowing. Gauge says full and then empty right away. Fuel sensors need replaced, check engine light is now showing. I notice many others with the same problem. Mine couldve caused a bad accident. Outrageously expensive and cost prohibitive to fix what I think is a safety issue. 70,000 miles is not a lot for this to have happened.”

   NHTSA complaint #11152585, filed 2018-11, 70,000 miles

   “Engine light came on and then fuel warning light came on even though I had a least 1/2 tank of gas. Filled up my gas tank, all lights were out. When I had approximately 1/2 tank again, the engine and fuel lights came on. I brought my car to my mechanic and was told the 2 fuel sensors need to be replaced at a cost of over $350.00. Upon online researching, I learned that there are many others who are experiencing the same problem. …”

   Engine

   Engine stalls while driving or decelerating

   • 85 complaints (24%)
   • median 80,000 mi at 7.8 yrs old (69 state mileage)
   • 2 mention a crash, fire or injury
   • owner-quoted repair $550 (median of 6 quotes)
   • filed 2011–2026

   Owners describe the engine shutting off without warning at low speeds, in traffic, on turns or when slowing from highway speed, with power steering and brake assist going away with it. Several say the car restarts right away, and that dealers and independent mechanics could not reproduce the problem or find stored codes. A few mention the throttle position sensor or throttle body as the suspected or replaced part. Reported from about 40,000 to 137,000 miles, often while decelerating or at low speed in traffic.

   1 related service bulletin

   What to check: Ask whether any stall codes or throttle position sensor work have been recorded, and note whether the engine idles steadily during a cold and a warm test drive.

   “I bought a 2009 hyndai Santa Fe in 2013 with only 40,000 miles on it and had no problems until december of 2018. I drove about 20 miles and on the way back home it started going as slow as 5 miles an hour; I don't know if it is an issue about being recalled but I still have 2 more years of payments and the truck isn't working!!!”

   NHTSA complaint #11182117, filed 2019-02, 60,000 miles

   “Just bought a 2009 Hyundai Santa Fe. I didn't even make it out of town before it stalled on me several times. I would hurry up put in park and start up. I took it to the Hyundai dealership and they said they seen this a lot of times before. Its the timing chain and tensioner. 2375 dollar fix.”

   Vehicle speed control

   Sudden or unintended acceleration reports

   • 67 complaints (19%)
   • median 39,900 mi at 5.1 yrs old (58 state mileage)
   • 15 mention a crash, fire or injury
   • filed 2009–2026

   Complaints describe the engine revving up or the vehicle accelerating without a command, sometimes with an owner's foot on the brake while stopped or parking, and in some cases with the cruise control engaged. Owners describe putting the vehicle in neutral to slow it down, and several say dealers could not reproduce the event or made no repair. Some complaints also mention a stuck accelerator pedal or a hard downshift with a lunge. Reported across a wide mileage range, from under 25,000 to over 100,000 miles, often at low speed or while braking.

   What to check: During a test drive, check that the pedal returns freely and that cruise control disengages when the brake is pressed; ask whether any throttle body or pedal sensor service has been done.

   “My wife and I were driving out to eat at a local restaurant. We were slowing down upon entering the parking lot. There was a loud bang and we lunged forward, like someone had hit us from behind. My wife had told me this had happened to her a few other times where she thought she hit someone or they had run into her. We took the car to the dealer and they said that they could not replicate the problem so there was nothing they could do for us. …”

   NHTSA complaint #10447767, filed 2012-02, 59,000 miles

   “I was driving on the highway and went to accelerate around another vehicle. The gas peddle was stuck full open even after letting off the gas. I made sure it was not the carpet holding the peddle down. The engine RPM's was revving very high also as the car kept accelerating out of control. After approximately 15-20 seconds the peddle released and everything was fine. The first occurrence was sep. 2012 and I've had a second occurrence on march 2013.”

   Air bags

   Airbag warning light stays on

   Mentioned in 4 of 60 sampled complaints

   Owners report the airbag warning light coming on and staying lit, sometimes shortly after a code for a front impact sensor was cleared with no parts replaced. In other complaints the light appears while parked or during ordinary driving and nothing was repaired at the time. A separate recall concerns recalibration of the occupant classification system for this model year. Reported from roughly 6,700 miles up to about 104,000 miles.

   Recall 12V354000

   What to check: Confirm the airbag light goes out after the ignition self-check, and ask whether the occupant classification system recall work was completed.

   “The vehicle was stationary stopped in a line of traffic on an exit ramp. Another vehicle, traveling at high speed, failed to notice traffic was stopped and struck my vehicle from behind. The force of the impact caused heavy damage to my rear bumper, bent the frame and crumpled the rear passenger side quarter panel, etc. It also launched my vehicle diagonally into the guard rail causing heavy damage to my front bumper and driver side quarter panel, etc. …”

   Brakes

   Rear brake noise and dragging / soft brake pedal

   Mentioned in 4 of 60 sampled complaints

   Complaints describe a squealing or squeaking from the rear brakes, with one owner told the rear brake shoes were corroded and another told a rear brake assembly did not move as freely as the others. Some owners report a soft or spongy pedal in cold weather that needs to be pushed near the floor before the vehicle stops. A service bulletin covers inspection of fluid around the caliper area and another covers rear wheel speed sensors on front-wheel-drive vehicles. Reported from about 12,000 to 43,000 miles, with the soft-pedal reports in cold weather.

   3 related service bulletins

   What to check: Listen for brake squeal on a slow stop and check that the pedal feels firm and does not sink; ask for the last brake inspection records, especially on the rear axle.

   “While traveling I heard a high pitch squealing noise. Unsure of what the noise was, I took the Santa Fe to my mechanic. He checked the brakes and showed me that the rear driver side brake housing did not move as freely as the others. His suggestion was to not drive more than about 2 hours at a time because there is the possibility of the brake system heating up and catching fire. Since the tire is right by the gas tank, that tells me there is a significant safety hazard. Any fire near gasoline has the potential to... …”

   NHTSA complaint #10523560, filed 2013-07, 34,000 miles

   “In cold weather (10-15 deg.) brakes are very soft/spongy. Need to depress brakes nearly to the floor before the vehicle will stop on dry pavement. After driving and pumping the brakes, they come back but not to normal condition. Dealer has had the vehicle for 3 days and says there is nothing wrong.”

   NHTSA complaint #10380789, filed 2011-02, 12,000 miles

Buying note. A pre-purchase scan for stored fuel level sensor and throttle codes, plus a test drive that includes a cold start, a slow stop and a deceleration from highway speed, will surface most of what owners describe here. Service records showing whether the airbag occupant classification recall and any valve cover gasket work have been done are worth asking for.
