2005 Hyundai Santa FE Problems

What owners report

Owners of this model year most often report an airbag warning light tied to the front passenger seat-belt sensor, and a cluster of complaints about delayed or surging acceleration from the electronic throttle. The airbag complaints tend to arrive at higher mileage, while many of the acceleration complaints were filed when the vehicle was relatively new and still under low mileage. A smaller but consistent group describes gas tank corrosion and leaks in road-salt regions, and front coil spring breakage.

1. 1
   Air bags

   Airbag warning light from seat-belt sensor

   • 70 complaints (32%)
   • median 93,000 mi at 10.0 yrs old (56 state mileage)
   • 4 mention a crash, fire or injury
   • owner-quoted repair $510 (median of 10 quotes)
   • filed 2005–2023

   Owners describe the airbag or SRS warning light coming on and staying lit, sometimes after starting the vehicle or at random while driving. In many complaints a mechanic or dealer traced it to a fault in the front seat-belt buckle or the passenger seat occupant sensor, and quoting repairs for a seat assembly, seat-belt buckle or sensor. Some owners report the light returning after a reset or a replacement, and several note the vehicle was not covered by the airbag campaigns listed for this model year. Mostly reported between roughly 75,000 and 135,000 miles, on vehicles well out of warranty.

   What to check: Turn the key to the on position and confirm the airbag light goes out after the self-check; if it stays lit, ask for the stored codes and whether the seat-belt buckle or occupant sensor has been replaced. Ask whether the vehicle was covered by the airbag occupant-classification campaigns.

   “Air bag light came on , took car to dealer, passenger seat belt buckle was replaced at a cost of 400. Dollers. A few months later the light came on again, and is still on. I can' afford to keep paying that kind of money to get it fixed again. I understand Hyundai has big problems with their air bag systems. I also have a 2006 Hyundai accent with the same problem.”

   NHTSA complaint #10592128, filed 2014-05, 80,000 miles

   “Seat belt light remains on, and advised by mechanic the air bag will not deploy due to a faulty connection in the seat belt buckle. Several reported issues with this, so why hasn't Hyundai recalled due to safety issue? My daughter of 21 is driving this vehicle as a second vehicle. I'm very worried about her safety.”

   Vehicle speed control

   Hesitation then surge or lurch on acceleration

   • 38 complaints (18%)
   • median 20,750 mi at 5.2 yrs old (32 state mileage)
   • 5 mention a crash, fire or injury
   • filed 2005–2019

   Owners describe a delay of a second or more after pressing the accelerator, followed by a lunge or surge as the engine catches up, sometimes spinning the tires from a stop. Complaints also describe the engine revving on its own, surging while coasting at steady speed, and jerking forward when pulling away. Dealers reportedly could not reproduce the symptom, called it a characteristic of the vehicle, or reprogrammed transmission settings without resolving it; in some cases the throttle body was replaced after a code appeared. Many complaints were filed at very low mileage, some within the first few thousand miles, with others spread up to about 100,000 miles.

   1 related service bulletin

   What to check: Drive the vehicle from several standing starts and at a steady 30-50 mph and feel for hesitation, lurching or an engine that won't settle back to idle. Ask whether the throttle system software update described in the service bulletin was applied and whether the throttle body has been replaced.

   2 excerpts from owner complaints in NHTSA records

   “My wife and I are experiencing a problem that threatens our safety every time we drive the vehicle. The problem has to do with delayed acceleration when applying the gas pedal, which causes fear when entering traffic or making a turn as opposing traffic approaches. The delayed acceleration is then followed by a lunging acceleration which reduces the feeling of control over the vehicle. …”

   NHTSA complaint #10155618, filed 2006-04, 8 miles

   “In the past 2 months this has happened more and more frequently. When stopped at a red light, the car will suddenly surge forward. I must throw it into neutral to stop it. Even when I am in park it will suddenly act like I am giving it gas when I am not. It is very scary and happening much more frequently.”

   Suspension

   Front coil spring breaks and punctures tire

   • 13 complaints (6%)
   • median 76,412 mi at 8.2 yrs old (13 state mileage)
   • filed 2010–2014

   Owners describe a loud bang or grinding noise, often while backing out of a driveway or driving at low speed, followed by a broken front coil spring that can puncture the tire or damage the strut. The vehicle is then typically undrivable and towed. Complaints mention no warning beforehand, and in some cases both front springs were found broken during inspection. Typically reported between about 42,000 and 99,000 miles, often on vehicles in salt-belt states.

   Recall 14V435000

   What to check: Have a mechanic inspect the front coil springs and struts for cracks or broken coils, and ask whether the springs were replaced and whether the vehicle was registered in a salt-belt state covered by the spring campaign.

   2 excerpts from owner complaints in NHTSA records

   “Driving down the highway a loud bang was heard. Discovered the driver front coil spring had broken. Fortunately no damage to the tire. I am surprised by the amount of similar failures reported. This certainly could have been much worse. I am a bit concerned that has not been investigated!”

   NHTSA complaint #10520331, filed 2013-06, 77,000 miles

   “Started to back my vehicle out of the driveway and heard a loud grinding noise. Stopped, got out and inspected to find that the front right coil spring had snapped and punctured my tire. Vehicle is undrivable and had to be towed. There was absolutely no warning. I have read dozens of other complaints about this same thing happening on other 2005 hyundais. Hyundai really needs to look into this problem/defect. Thankfully, I was not driving at 55 MPH on a highway as I'm sure serious injury/damage would have occurred.”

   Brakes

   Brake pedal soft or pulling, ABS warning

   • 35 complaints (16%)
   • median 53,000 mi at 8.2 yrs old (29 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2005–2025

   Owners report a brake pedal that travels to the floor, a brake warning light, leaking calipers or fluid loss, and vibration or warped rotors that returned after resurfacing. Some complaints describe the engine racing when the brake is applied at low speed, and dealers reportedly could not duplicate the symptom. Reported from as little as a few thousand miles up to roughly 80,000 miles, with rotor complaints appearing early.

   4 related service bulletins

   What to check: Test the brake pedal for a firm feel with the engine running, check for fluid weeping at the calipers, and ask when the pads, rotors and fluid were last serviced.

   “Braking sometimes causes the motor to race and hard braking makes it worst. This has occurred several times and I felt lucky to avoid an accident. It happens when stopping at about 10-20 miles per hour. Dealer always cannot duplicate same result I have seen other complaints on line so it is not my driving.”

   NHTSA complaint #10266542, filed 2009-04, 53,000 miles

   “The car dealer is telling me that all 4 tone rings and speed sensors on my Hyundai Santa Fe are bad and need to be replaced. One was replaced 4 months ago under warranty. Now they say that the other 3 are bad. I have less than 53,000 miles on my car.”

   Fuel system

   Rusted fuel tank leaking fuel

   • 13 complaints (6%)
   • median 92,000 mi at 11.6 yrs old (12 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2008–2019

   Owners in road-salt regions report a strong gasoline smell inside and around the vehicle and, on inspection, a rusted or fractured fuel tank leaking from behind its plastic shield. Some dealers and mechanics replaced the tank; others told owners the repair was not covered or only partly covered by warranty, and some complaints note a fuel odor that continued after a canister replacement. Generally reported between about 55,000 and 190,000 miles, mostly on vehicles driven where salt is used on roads.

   What to check: Look under the rear of the vehicle at the fuel tank and its plastic shield for rust, staining or damp spots, and check for a fuel smell after sitting. Ask whether the tank has been replaced and, if the vehicle spent its life in a salt-belt state, request the repair history.

   2 excerpts from owner complaints in NHTSA records

   “Gas tank is corroded and leaking fuel due to road salt because I live in the northeast. I was notified that Hyundai has extended the warranty on model years 2001-2006 up to 150,000 miles. I do not believe this extended warranty should have a mileage restriction, and I also do not believe this should be an extension of the warranty but an all our recall by Hyundai. Cars are leaking gas! My car has no other rust on it and I keep my car clean and parked in my garage. My gas tank should not be rusted out on a car that is 10 years old. …”

   NHTSA complaint #10840195, filed 2016-03, 163,000 miles

   “Purchased a 2005 Hyundai Santa Fe and found afterward that the fuel tank was leaking from inside the plastic shell surrounding it. Discovered at that time that this is a common problem in states that have corrosion (road salt) and it is difficult to spot because of the plastic shell. Found that Hyundai had not done a recall but extended the warranty, but only an additional 5 years or 50, 000 miles on the fuel tank. …”

   NHTSA complaint #10918517, filed 2016-10, 190,000 miles

Buying note. On this model year, check the airbag warning light and front seat-belt sensors first, since that is the most common complaint, and budget for front suspension and fuel-tank inspection if the vehicle lived in a road-salt state. A test drive at low speed and from several standing starts will show whether the throttle hesitation or surging is present.
