Electrical System Problems of Hyundai Santa Fe - part 1

I bought the 2024 Santa Fe xrt pro new off the lot sept. 2024. Brought it in for 3 different recalls but the electronic system panel is new: the panel lit up with every warning sign it can convey: from the engine light to the coffee break, to the emergency warnings. This has happened twice; once a few weeks ago and again a few days ago. My car is back at the dealership for repair to the electronic panel. The first time, the dealership replaced the entire panel as it is still under warranty. It's at the shop again and I don't know what they will do this time. I would trade it in, but the trade-in value sucks.

The contact owns a 2025 Hyundai Santa Fe. The contact stated that while driving approximately 65 mph, the vehicle unexpectedly decelerated to 25 mph with a “vehicle will shut down” warning message displayed. The contact stated that the engine then began to shut down, and although the accelerator pedal was depressed, the vehicle failed to accelerate and stalled. The failure occurred on multiple occasions, requiring the vehicle to be towed each time. The vehicle was towed to the dealer; the vehicle was not diagnosed or repaired and the contact was informed that the failure could not be duplicated. The manufacturer was made aware of the failure and multiple cases were opened, the failure mileage was approximately 3,300.

The right side power captain seat in the second row began to fold down without the button being pressed. It happened with and without the seatbelt plugged in. It came down while my toddler was in her rear facing car seat and began to crush the car seat and push on her feet. The chair would not stop the power seat motors even with both my wife and myself pushing back on the seat trying to free our daughter from the car seat. It continued to push down the moment there was more space to collapse. No errors or messages or engine lights of any sort were displayed anywhere. Even after removing our daughter it happened several times again.

"what component malfunctioned. . . ?" - electrical system (suspected) "how was safety put at risk?" - we were unaware if the dashboard instruments were reading correctly. We also couldn't lock/unlock the doors or open/close the windows. The tailgate would also not open. "has problem been reproduced?" - not yet - plan to have the service center inspect. "has vehicle been inspected by the manufacturer?" - no "were there warning messages or symptoms?" - yes, when the issue occurred. The vehicle reported 13 warnings/alerts. Happened for the first time on 5/2/2026 general description: while the vehicle is parked or idling after sitting for a period of time, the dashboard suddenly displays approximately 13 warning alerts simultaneously, including a message stating "check emergency stopping function" among others. During this condition, multiple vehicle systems become inoperative, including: - power windows - could not open/close - door locks - could not lock/unlock - tailgate operation - could not open (it was closed) the vehicle appears to experience a system-wide electronic failure affecting both body controls and safety systems. The condition is intermittent but has occurred multiple times. Restarting the vehicle does not immediately resolve the issue. After driving for a period of time, the vehicle eventually returns to normal operation. This is a safety concern because: - critical safety systems (automatic emergency braking / driver assist features) are (potentially) disabled - basic vehicle functions (locks/windows) are unavailable. This is a concern if the door can't be opened and one needed to exit through the window in an emergency. - the failure occurs without warning and cannot be reliably reproduced on demand this appears to be a broader electrical or communication system failure rather than a single component issue.

On April 27, 2026, my 2025 Hyundai Santa Fe experienced an intermittent electrical/system malfunction affecting multiple vehicle systems at the same time. Multiple orange warning lights/messages appeared on the dash, including driver-assistance warnings and the master warning triangle. At the same time, the front turn signal stopped working, causing rapid flashing; the power locks stopped working; the windows would not roll up or down; and the rear liftgate would not open using the key fob or exterior liftgate button. The vehicle/component is available for inspection upon request. This created a safety and access issue. The malfunction affected exterior signaling, locks, windows, and rear cargo access. My dog was in a crate in the rear cargo area, and I could not open the liftgate normally to access him. The failure of locks/windows/liftgate could create a serious emergency risk if a person, pet, or cargo needed to be accessed quickly, and the turn signal failure affected my ability to safely signal to other drivers. The issue lasted approximately 30–40 minutes and did not immediately clear after turning the vehicle off and back on. It later returned to normal on its own. This has happened more than once. The vehicle was taken to a Hyundai dealership for inspection. The dealer has been working with Hyundai techline, but as of now they have not been able to reproduce the issue or find active diagnostic codes. I provided video evidence of the dash warnings from the incident. The dealer advised that scans currently show systems operating as designed because the issue is intermittent and not occurring during inspection. There were no prior symptoms before the failure. The warning lamps and messages appeared at the time the malfunction occurred. Seek reimbursement for rental car fees and diagnostic fee.

When the car is off and in park and you go to turn on the car on by pressing the brake and power button button, the electrical system doesn't register and wont turn the ignition on and the brake gets stuck and you cant start the car. The same thing happens when the cars auto ignition is turned off at a red light then you press the gas to go but it doesnt show the gear is in drive and the ignition turns off and wont turn back on. The major safety concern is when this happens at a red light or in traffic and my car stalls and I am at risk of getting rear ended. I have taken the car to the dealership twice now for the same issue. The first time they claimed it was fixed but it wasnt and now it is at the dealership again for the same issue and I have not received any remedy yet. There is no warning to this issue it happens out of know where and is extremely dangerous. The issue has been going on for several months.

The steering left side electrical components quit working at the same time without warning. This is all related to the air bag clock spring a serious safety defect that disables the airbag and possibly horn. I have taken the vehicle to a Hyundai dealership for diagnostics and this is what was found. "needs immediate attention [primary]: ssd : steering or suspension diagnosis air bag - clockspring assembly / spiral cable: clock spring has shorted out causing all the buttons on the left side of the steering wheel not to work this assembly consists of a clock spring, which is a coil that retracts and expands inside its housing as the steering wheel turns. Its function is to maintain electrical continuity for all the components on the drivers airbag.

3 times now, I am driving and the vehicle goes into limp mode, the "d" on the dash is flashing but the vehicle sends no codes. The tech said the vehicle can immediately delete the code and they can't fix it if they can't duplicate it. It also hesitates when accelerating and is dangerous to myself, my 4 children and anyone driving around me when it goes into limp mode. There is no code, therefore they say they can't do anything about it.

I was told by a mechanic that something electrical is wrong with the vehicle it causes the engine to misfire. Different issue than before.

I was driving on March 20, 2026 at about 12:00 pm when I suddenly noticed smoke, a strong gasoline smell, an oil smell, and a burning odor coming from the vehicle. I pulled over immediately because I believed the vehicle was unsafe and at risk of fire. The vehicle had to be towed. An independent repair shop later found a fuel leak at the high-pressure fuel line / fuel pump area, a loose ground wire on the right-hand side of the engine, a valve cover gasket leak, and engine timing chain noise. I was informed that gasoline had sprayed throughout the engine bay. This created an immediate fire hazard even though no actual fire occurred. This problem was especially concerning because the vehicle had been inspected and serviced by an authorized Hyundai dealer in December 2025, less than about 3,000 miles earlier. The loose engine ground wire and fuel leak raise serious concerns about vehicle safety and the adequacy of the prior inspection. I contacted Hyundai the same day and reported this as a fire-risk safety issue, but I did not receive timely assistance. Because immediate dealer service was not available, I had to authorize emergency repairs at a local shop for safety reasons. No warning lights were noted before the incident. The failure was confirmed by the repair shop.

After performing regular oil changes, and even a new fuel pump sensor, I experienced an issue. Last oil change was within the past two weeks. Driving home from the mountains, I heard a knocking sound from the engine bay. I narrowed it down to all gears above 2500rpm, increasing knocking with rpm speed. I took it easy on the engine, mostly coasting down the mountain. Suddenly during acceleration on an uphill, a pop sounded, and copious white smoke started coming from the engine bay. I pulled over despite having no power brakes but I was fortunate to be near an off ramp in a rural area. Trying to troubleshoot roadside, I noticed fluid on the tie rod, but I wasnt able to determine what kind of fluid it was. When I try to start the car, there is one single click, the engine wont even attempt to turn over. Oil, battery and check engine lights are all on. After towing, I found that the fluid leaking from the vehicle is oil. The vehicle is currently at a transmission shop, but from my research, this isnt a transmission issue but a blown rod bearing the Hyundai engines are know for. I will be contacting a dealership to see if they will at least confirm my diagnosis.

Engine rattles noise when starting the car after sitting for more than an hour it makes that sound another issue is that when I turn the headlights on all interior lights shuts off including the instrument cluster radio and ac climate control buttons.

Bottom brake lights will not work but top high brake light works. I was stopped by police three times. They state all three brake lights must operate.

The vehicle experienced a significant failure of the body control module (bcm). This resulted in multiple electrical malfunctions, including don't detected the key, despite the low mileage (12,000 miles), the electronic systems have proven unreliable, and the vehicle is currently undergoing warranty repairs at the dealership. "the sudden failure of electrical components could lead to a crash or leave the driver stranded in an unsafe location. I am concerned about the long-term reliability and safety of this vehicle’s electronic architecture. " after arriving home and shifting the vehicle into 'park', the car began to roll backward on its own. The vehicle continued to move until it struck my garage door. This incident occurred unexpectedly after the transmission was supposedly secured in park. It was necessary to apply the brakes to make it stop. Although the physical damage was minor (scratches), this unintended movement represents a severe safety risk that could have resulted in a serious accident or injury. " I've also noticed that it makes strange shifts in the transmission when going down a steep hill.

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. The contact called 911, an independent mechanic, her father, and the fire department. The fire department was able to extinguish the fire and disconnect the battery. The mechanic determined that the engine cover was burned. There were no reported injuries. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The contact indicated that the failure was related to NHTSA campaign number: 11e040000 (equipment). The insurance company referred the contact to the NHTSA hotline for assistance. The manufacturer was not contacted. The failure mileage was approximately 145,000.

2024 Hyundai Santa Fe purchased new in may 2024. On three occasions since December 2025, while driving, the dashboard went completely black as if the vehicle shut off. The Hyundai startup logo then reappeared while the vehicle was still moving, and the vehicle lost acceleration. The most recent event occurred at highway speed, approximately 65-70 mph, requiring us to coast to the shoulder. No warning lights appeared before the event. A video of the most recent incident is available. Dealer inspected vehicle but could not duplicate the problem and reported no error codes.

The passenger-side doors do not latch properly and may open after closing. This creates a safety risk while driving. The issue occurs continually and has worsened over time. Vehicle has approximately 106,265 miles. This causes the auto door locks no to work.

All normal sounds completely stop working, no audio or volume at all: no turn signal, no collision warning, no gps audio, no radio; no hands-free phone volume. Hyundai service department advised they have never heard of this type of incident. All warning systems are completely silent.

On the morning of February 20 2026 at around 6:35am. I was on my way to work when the engine light started flashing and the speed started to decrease. I was traveling on a major highway in heavy rain with a lot of traffic. I had to put on my hazard lights and quickly pull off the road. The code given is p1326 which has to do with the engine and wiring harness. I just purchased the vehicle on Jan. 17 2026. The carfax stated no open recalls.

After turning off the radio with the push button control the instrument cluster and navigation display panel went completely dead black. After pushing multiple buttons several times the panel came back to life. This has not yet been reported to the dealer. On 12/12/2025 this same vehicle also experienced faulty engine / power train components which required replacement @1199 miles. Throttle body assembly and torque converter assembly which caused loss of power when accelerating onto a high speed parkway attempting to reach @55mph along with excessive vibration when brakes were off. Took dealer 22 days to fix the problem.

Incident description: I am reporting a recurring and dangerous safety defect involving the adas (advanced driver assistance systems) on my 2024 Hyundai Santa Fe hybrid. On multiple occasions, the vehicle has exhibited uncommanded steering input. Even when the lane keeping assist (lka) system is manually disabled by the driver, the vehicle software overrides this command and re-activates the system without driver input, causing unpredictable steering behavior. System failures & error codes: the vehicle intermittently displays a "check forward attention warning system" failure. Dealership diagnostics have confirmed the following historical fault codes related to module communication: •c164286, c168886, c16b902, c28b981 related safety recalls: this vehicle is currently subject to recall 265 (NHTSA 24v561000) for main floor wiring harness chafing and recall 288 (NHTSA 25v808000) for rearview camera wiring tension. I believe the uncommanded steering and camera failures are direct results of the electrical interference or harness damage described in these active safety recalls. Safety risk: the uncommanded steering override creates an immediate risk of a crash, especially in high-speed highway conditions where the vehicle may unexpectedly pull against the driver's intent.

Vehicle experienced sudden loss of power while driving. Transmission warning and abs warning lights appeared at the same time. The vehicle would not shift properly and began skipping and dropping gears. Smoke was visibly coming from the center underside of the vehicle near the transmission area. There was a strong burning oil or rubber smell inside and outside the vehicle. This created a serious safety risk due to loss of acceleration and potential fire hazard from smoke and burning odor. The issue has been intermittent since early ownership, including jerky shifting and hard engagement. The dealer documented dual clutch transmission communication faults and abs faults but returned the vehicle the same day stating it was a loose ground. The problem has continued after repair. Vehicle is available for inspection. The defect involves the powertrain and related electrical systems.

Needed to use horn in an emergency situation and that's when I found out my horn no longer works. 20,000 miles on 2023 Hyundai Santa Fe.

-shift lever in transmutation stopped working so car would go into auto shut off and then would not drive once I took my foot off the break. Would not switch gears or drive.

I turned off the car and went inside the house. I was outside and could smell smoke. I walked to the front of the house and saw my neighbor who was calling 911 due to flames from my engine. The flames reached the yard and my garage where minor damage occurred. The vehicle was completely engulfed in flames before the fire department extinguished it.

I tried to drive my 2025 Hyundai Santa Fe hybrid; the vehicle displayed a gear selection error message stating something like "gear already selected". The vehicle would not shift properly and would not power off or restart. I attempted multiple shutdown and restart attempts using the start/stop button with no success. The vehicle remained in this condition for about 30 minutes and would not allow normal operation or shutdown. Due to safety concerns, Hyundai roadside assistance was contacted and a tow truck was dispatched. Before the tow arrived, the vehicle spontaneously allowed shutdown without any intervention. This was a safety related failure involving the shift-by-wire system and vehicle power-down logic. The issue occurred without warning and left the vehicle inoperable. The vehicle had app 7150 miles at the time of the incident.

My starter failed while out shopping. No issues starting the car departing from my home, but would not start in the store parking lot. My mechanic did not provide the broken part for inspection however everyone commented that is was very unusual for it to fail as I only have roughly 25,000 miles on it. My mechanic also mentioned that this was 2nd 2018 Hyundai sante fe in the past week he had to replace the starter on that vehicle had 60,000 miles. There were no warning lights prior to the event, I suspected it was the starter after having a new battery installed and no success starting because of the lights that remained on on the instrument panel.

What component or system failed or malfunctioned, and is it available for inspection upon request? horn how was your safety or the safety of others put at risk? my horn stopped working - cannot use it when driving to warn other drivers - safety issue has the problem been reproduced or confirmed by a dealer or independent service center? not reproduced, but dealership has confirmed the horn stopped working on three separate occasions. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? dealership - three times were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? no. Hyundai dealership said my fuse blown on three separate occasions causing the horn to stop working. My horn stopped working a few months ago, then about a month ago and again last week - all due to blown fuses to which the dealership has no explanation.

Horn stopped working at 47,474 miles check tire pressure system light is on, poor sensor at 45,650.

Took my 22 sante fe to the Hyundai dealership to have the blower motor checked since I have no air flow in my car. Dealership informed me that the engine harness needs replaced and that it melted the fuse box under the hood. So, I am not able to replace my blower motor at this time due to the melted fuse box. Dealership also advised that they have seen the same problem in multiple 22 sante fe. And that there is likely more with the same issue within the united states. I have been noticing a melting/hot smell in the car before the airflow quit and I took it to the dealership to be diagnosed.

Was coming off an exit on the interstate and started slowing down. My brakes act like they didn’t want to work. Grinding and the pedal was twitching under my foot. The car stopped thankfully, but then all linda of lights came on the my dash and will not go off. And 3 warning come up!.

The vehicle intermittently fails to reverse properly, hesitates, jerks, and at times locks despite no obstruction present. This occurs during normal use and creates a serious safety concern, particularly when backing out of parking spaces or into traffic. In addition, the vehicle exhibits ongoing electrical issues, including intermittent warning lights, rearview camera distortion or failure, inconsistent system operation, intermittent inability to unlock using the key fob or door handle, and the vehicle fan or air system continuing to run for extended periods after the vehicle has been turned off. These issues occur without consistent warning and have not been resolved despite multiple service visits. The vehicle is also subject to an active safety recall (NHTSA recall 26v218000, manufacturer recall 298) involving the front seatbelt anchor. The recall remains unrepaired, with no remedy currently available. I have personally experienced the seatbelt becoming stuck and not releasing properly, which presents an additional safety risk. The vehicle also experienced a battery failure. I was initially informed that the battery could not be replaced without cost; however, it was later replaced. Despite repeated concerns, the hybrid battery system was not tested or evaluated, and this remains an unresolved issue affecting vehicle reliability and safety. Additionally, the vehicle has experienced tire tread separation and peeling requiring replacement. This is not consistent with normal wear and may indicate alignment, suspension, or other underlying vehicle-related defects. The vehicle has been inspected by the dealership multiple times; however, the issues were not reproduced and no corrective repairs were performed. These problems are intermittent and occur during regular day-to-day operation. Collectively, these unresolved issues present an ongoing safety risk to the driver and others.

I am writing to formally report an incident involving the service department at lakeland Hyundai (1500 w memorial blvd, lakeland, FL 33815). My 2007 Hyundai Santa Fe was brought in on 12/31/25 for an active engine recall involving the cylinder head cover oil leak repair (recall code 976 / campaign 24-01-026h). The vehicle was driven into the dealership in proper working condition. I was later informed that allegedly stripped bolts for the cover would require an out-of-pocket cost of $483. 36, despite this being a recall repair. There was also a required upper timing chain guide repair quoted at $58. 38 to complete the recall work. When I was called in on 01/12/26 to pick up the vehicle for completed work, I was charged $29. 99 for a multi-point inspection related to the recall, yet no documentation or billing was provided for the timing chain guide repair I was told was completed. Upon attempting to leave the lot, the check engine light was on and the vehicle immediately began shaking violently and producing a loud noise. The service representative could not identify the cause and later advised there was nothing further they could do, citing a p0300 code, and instructed me to return the loaner and retrieve my now-undrivable vehicle. My vehicle remains at lakeland Hyundai and is undrivable due to issues that arose immediately following recall service. I respectfully request guidance and resolution regarding responsibility for the damage, loaner coverage, and loss of transportation.
