CarComplaints.com Notes: The 2012 Hyundai Santa Fe has a problem with the engine stalling while driving. Both our data & the NHTSA's complaint data show a significant defect trend at low mileage.

In a 2-page letter to owners in August 2014, Hyundai claims the engine stalling only occurs under a "specific set of operating conditions".

However a class action lawsuit filed around the same time details multiple claims from Sante Fe owners that claim the engine stalling happens at any time, under any conditions.

The contact owns a 2012 Hyundai Santa Fe. The contact stated that upon exiting the vehicle, all four doors and tailgate would lock independently. The contact stated that over some time, all four doors failed to unlock while outside the vehicle with the key fob. The contact was only able to unlock the driver-€™s side door with the key. The contact had initially taken the vehicle to a dealer where she was informed that the door actuator needed to be replaced; however, after the repair, the failure persisted. The contact then took the vehicle to an independent mechanic where it remained in their possession. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 84,000.

I bought the car used and initially didn't have any issues with it. About a year into having the vehicle I saw that the battery light came on momentarily and then went off. Not noticing anything different with car I thought it was no issue initially. Got the car checked battery checked out after I noticed it happen a few more times but the battery passed testing. Eventually the right headlight stopped working. Thinking it was just an issue with the light I attempted to replace it but the light never came back on. Then the left turn signal stopped working. Got the car checked out and was told that the issue was more than likely an issue with the wiring, either a short or potentially burned wire. Took the car to my local dealer and was told the the headlight assembly was the issue and that it would about 1400 to 1500 dollars to replace. Told the dealer what I was told about the wiring issue and was told that I would have to pay for that and the headlight assembly if replacing the headlight assembly didn't fix the issue Managed to get the headlight assembly replaced on my own and the issue still persists. After initially changing the assembly the headlights worked, but on of the running lights wasn't as bright as it should have been. Here recently the right headlight is out again, along with the left taillight and left turn signal.

when a bluetooth device is plugged into the available plug(auxillary plug) in the front dash of the vehicle the radio/CD/phone connections work on and off(mostly off) if lucky you might hear the stereo for a few minutes then it goes off again for days. when unplugged the radio keeps working. My drivers side power window has not worked a few times. The available connection for the cell phone does not work all the time. There is some kind of electrical problem in my vehicle. These ongoing problems have been going on for about 1 1/2 years after I bought the vehicle.

When driving the vehicle, the vehicle will lurch forward. This could be done as I am accelerating, as I am breaking, or as I am coasting. The dashboard lights will then all come on including the check engine light. The vehicle will start to shake and unable to accelerate. Forcing you to pull off and park the vehicle. When you turn the vehicle off and turn it back on it's like nothing ever happened. The vehicle has also has instances where the RPM gage registers zero, even after you are accelerating. We have had the spark plugs replaced, the fuel system line cleaned out, we started noticing the problem in February is 2020 and the frequency of the problem has only increased. This now happens about every 3-4 days. I have 2 children and I do not feel safe driving in this car with them. I believe that my vehicle should be a part of the recall number 20V746000, or from hyaundai's recall number 198.

My ESC, dbc, and ABS warning lights all illuminated at the same time this morning. There are many complaints of this happening on numerous Hyundai forms. Folks have been told to replace hubs, sensors and assorted other pieces. Most do not work costing hundreds of dollars. My particular vehicle had the lights come on maybe 6 or 8 months ago. Go off and come on again and off again. I've ignored them not noticing any driving impact. But the car is warning me that it isn't safe to drive the car. This is not a one of or two or three issue. This from another owner;all three light illuminated on my 2011 Santa Fe so I changed my front right ABS speed sensor which was the cause of the lights, but the dash lights are still illuminated. Took it to the dealer and they said there is a short in the ABS system wiring harness. What's the cost to fix? $4500 really! I think a recall is due for this problem.

The vehicle stops running in the road without warning and is unable be restarted. Attempts to charge the battery fail. When taken to be evaluated by the brand dealership, they only change the battery and say that it has been fixed. Within 3-4 weeks, it will shut down in the road again. This has occurred four times, and each time, I take to be serviced and they are unable to reproduce the failing issue. I have reached out to corporate, and have quickly dismissed my case. There was a class action lawsuit in 2016 concerning the exact issues I am experiencing with the vehicle. I would think with this type of documented liability, there would have been a recall on the vehicles or a warning notice dealerships were required to present with the sale. I do not feel comfortable trading the car in as the issue will be transferred to another consumer.

My son was driving with 3 other young people in the car at low speed and the car began making a loud knocking noise and stopped in the middle of an overpass. He had to coast backward off the overpass. Thank god no one was behind them or they could have been killed! when I called Hyundai customer service they said the 2012 had 'no recalls' but when I reviewed the information on other recalled vehicles different year but same issues. My question is are people going to have to die for something to be done about this" why aren't these 2012 Santa Fe's being recalled like the others? please make this a mandatory recall so no one is killed before it's too late. Please! mother's love for her child and his friends. Recall this car!! he has not had the chance to bring the car to the dealership yet as he was afraid to drive the car. It was towed to his apartment because it was 9:30pm. He is not familiar with the area because he's in college for his masters degree. What are we supposed to do" help please! electrical lights came on vehicle made a loud knocking noise and stopped in the middle of the road the car starts but makes the loud noise

While driving at freeway speed, car shut down unexpectedly, and restarted. During interim 20 seconds, attempted to pull vehicle to left shoulder as I was driving in far left lane. I felt "engine drop" or a feeling whereas the car no longer felt powered, cue that the engine had went off. Power steering went manual along with other power assist devices like power steering. On dirt shoulder of freeway attempting with manual brakes and steering to bring vehicle off roadway. Vehicle restarted during maneuver. Still moving at safe speed attempted to merge back onto the freeway, having not yet decelerated enough yet to continue to pull over....clear and dry conditions in North la county. This vehicle however has always had "overly responsive" or "very tight" steering, for lack of better terminology. I leased the vehicle and did not fully realize, until some time passed, what this 'steering characteristic' would mean in the future, in an event requiring accurate and responsive steering combined with the ability to maintain control. The sudden engine power resuming, combined with, what this writer would describe as "tight steering" to begin with, made the vehicle roll. The vehicle, with what felt like a "high center of gravity" always felt like it would roll if one were to have to move quickly to avoid something in the road for example. I did not realize this feature during my test drive. Being a lessee I was obligated to keep the vehicle for 3 years. The vehicle rolled several times while crossing 3 lanes of an occupied northbound highway 14. A sudden jolt resulted in a fracture of L1 vertebrae. During roll, jack became undone from where it was factory mounted underneath lift up cover, and had never been removed. Flailing around in the vehicle now was this heavy scissor jack bouncing around in the vehicle compartment with me. I am glad to be alive.
