Owner reports
Selected complaints filed with NHTSA by 2010 Hyundai Santa Fe owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2010 Hyundai Santa Fe. The contact stated that while driving at an undisclosed speed, the vehicle stalled. No warning lights were illuminated. The vehicle failed to immediately start, but started after several attempts. The vehicle was taken to an independent mechanic, who replaced the starter, oil filter, and engine filter, and changed the oil. On a hot day, there was a loud sound coming from the vehicle, and it was noticed that the unoccupied vehicle was attempting to start independently. The contact unlocked the vehicle and opened the vehicle door, put the keys in the ignition, and continued to crank for approximately four minutes. The accelerator pedal was pumped, and the vehicle stopped. There was smoke coming from the vehicle, and the vehicle eventually stopped. There were flames coming from the vehicle. …
Odometer Fraud. The contact purchased a 2010 Hyundai Santa Fe. The contact discovered a mileage discrepancy after the purchase. The vehicle was a private sale. At the time of purchase, the mileage was 142,000. It was later discovered, during a VIN check, that the mileage was 223,000. The mileage was last recorded in June 2025. The local Police Department was notified of the fraud. However, due to insufficient information about the seller, no report was filed.
My 2010 Hyundai Sante Fe caught fire on 9/27/23 while I was operating the vehicle and this fire ultimately caused my electrical systems to overheat and the wiring to melt. There was no indication that my alternator was about to fail (no battery light on my dash, no issues with starting my car) and I regularly maintenance my car with oil changes, tire rotations, and I redid my whole brake system in August 2023. My safety, the safety of my passenger, as well as the safety of ALL the patrons in the building that sat above the parking garage I was located in when the fire was burning were put at risk by this incident. My passenger acted quickly enough to put out the fire before anything more serious occurred, however according to my insurance we didn't let the fire burn long enough for there to be damage... even though my electrical harness is melted from it overheating due to the fire... …
The battery warning light illuminated. The alternator was not holding power. I was on the freeway and the vehicle lost total power. After seeing a certified mechanic I was made aware of a oil leak from the valve gasket that was leaking on to the alternator wires and caused it to loose power. There is a recall for the same vehicle with the exact same issues, however my vehicle is not on the list of vehicles affected by this recall.
I was driving my 2010 Hyundai Santa Fe, the blinker switch started frantically clicking, I than heard electrical sparks from the steering column and than smoke starting coming from the steering column where the blinker shaft was located. Hyundai has had my vehicle for 2 weeks, leaving me and my 8 month old carless. The dealership and cooperate has said that they have never heard of this happening before, and has not given me a courtesy call or vehicle updates. I looked on this website, safecar.org and indeed, I found someone who has encountered the same issue (please see NHTSA id number 10629458). I feel that this is a major safety concern and needs to be recalled immediately with the other recalls in place.
Purchased vehicle brand new, the rear brake lights failed and I was rear ended @ 65 MPH. Vehicle suffered $14,000 in damage with a bent frame. The value of my vehicle is now diminished drastically and it is reported in car fax report. Approximately 2 years later vehicle was recalled for faulty brake lights and the brake switch was replaced at the dealership. I should not suffer financial loss due to negligent parts that were manufactured and installed on this vehicle.
A 2010 Hyundai Santa Fe was involved in a front end impact . The vehicle was taken to a local body shop for repairs. In the normal course of repairs, the shop replaced the components of the supplementary restraint system and sent the vehicle to the local dealer to check for error codes and to reset the system. One of the error codes would not clear. The dealer, in washington state advised the repair shop and us that pursuant to a TSB,01-90-013, Hyundai recommends that the wiring harness also must be replaced in addition to the standard parts of the airbag system, when the air bags are deployed. There was no direct damage to the wiring harness and this appears to be some unique requirement designed into the harness by Hyundai. It is unclear why this is required or what unique feature was built into the harness that demands the replacement of the entire harness. …
Santa Fe blinker switch on steering column started smoking. I have a video as evidence of the smoke and mileage of the vehicle. Hyundai refused to fix the problem at no cost even though it was a clear and present danger to me and my family. Blinkers started staying on at all times when ignition was on. Blinkers would go left and go right, but when in the center position the left turn signal stayed on or the audible part of the blinkers could be heard with no signal light. Smoke came from the steering column and the vehicle smelled and still smells of an electrical fire. I took a video that clearly shows smoke coming from the blinker switch in the steering column. Please ask if you would like a copy of the video. I called Hyundai customer service and told them and I also asked to the dealership to take care of it. …
Passenger rear door (right rear) lock actuator mechanism failure. Door is locked and **cannot be unlocked or opened from inside or outside the car**, whether by manual or key fob method. Manual door lock button (on right rear door) inside car difficult to actuate, door handle actuation (cable?) seems like it May be detached (very easy to actuate door handle, no resistance). Worked fine, until it failed with no warning. Tried to open right rear door and was unable to. I rarely use this door, so it May have failed prior to when I noticed it. Approx 59,000 miles when problem noticed. *serious* safety issue if door malfunctions with passengers in car--the door is 100% useless--and it could happen to any of the doors I assume.
This car has stalled at least six times in the past six months, usually as we are deaccelerating and in a downhill position (ie: driving slowly down a mountain, coming to a stoplight going down a hill, etc.). It has a new engine as of summer 2020. We took it to a local Hyundai dealership and they ran a general diagnostics check-up with no results. We have searched this problem online for a solution and see many others reporting similar stalling concerns, but when we put our VIN into the recall system, there are no recalls affiliated with this car. The car drives great otherwise, but the stalling is very concerning.
