Electrical System Problems of Hyundai Santa Fe - part 1

Multiple warnings flashing across dashboard regarding lane assist and emergency stopping. The auto hold came on by itself and turned orange. The emergency parking brake came on and stayed on. The warnings kept dinging every 30 seconds while driving and lit up every icon on the dashboard. Once parked I turned off lane assist, but it continued to trigger warnings. Lights flickered in park and with engine turned off. There is a clear malfunction going on somewhere.

It seems like the computer or electrical system is failing in the main ecu and the entertainment console. The car's entertainment console will blink when driving over a bump or while braking. It will disconnect from apple carplay and won't reconnect. More importantly, it will turn the car completely off while braking sometimes. This happens while moving. There was an incident where the car didn't wake up and unlock with the key fob first thing in the morning. I had to unlock it with the physical key. Once I opened the door th car woke up and the alarm went off.

I was driving the hybrid vehicle uphill on a highway and there was traffic so we were driving under 5 mph for about 20 minutes. When speed picked up I went to accelerate and the vehicle, it never accelerated when I depressed the gas pedal, and stayed in electrical mode rather than switching over to gas. The vehicle then shut off in traffic and I could not pull over safely on congested two lane interstate 17 and I was afraid as vehicles were swerving and driving past and we could not get out safely. The "check hybrid system, stop safely" warning came on the dash. This vehicle at the time only had 8,808 miles on it and is relatively new. I brought the vehicle in to the dealership but they said "tech scanned for codes. No dtc present. No warnings on cluster at this time. Tech checked for ecm sw upgrades. None available. Tech road tested vehicle without any issue. No repair performed at this time. " when I picked up my vehicle they only put that only the check hybrid warning light came on and left off their report that my vehicle completely stopped working.

While driving on a highway at approximately 60 mph, the vehicle abruptly suffered a catastrophic loss of power and entered "limp mode," creating a severe safety hazard on the roadway. The vehicle was safely maneuvered and pulled over to the side of the road. Upon shutting the vehicle down and attempting to restart it after a few minutes, the powertrain completely failed to engage, refusing to shift into either drive or reverse. The vehicle became entirely disabled and required a flatbed tow to the dealership. ?dashboard warning messages: - ?"transmission control system" - ?"check hybrid system" ?diagnostic trouble codes (dtcs): - ?p177700 (transmission / hybrid powertrain control malfunction) - ?p178400 (transmission control system / electric oil pump or actuator circuit fault).

On 3 separate occasions the vehicle has suddenly quit going. Twice going through an intersection after taking off. The third time going up hill near my house. The car would only go 10 mph. A message would come up on the dash that reads " transmission system error, check transmission oil immediately. That was not the problem. The Hyundai dealership performed a recall update on the computer the first time. But that didn't solve the problem as a week later the same thing happened . Again the car was towed to the dealership. This time another transmission service was performed according to a tech line information. After retrieving my car from the dealership I drove it for less than a week and the same thing happened. The car was towed back to the dealership again. Now the dealership says they can't do any repairs as the computer will not store any malfunction codes so they will know what to repair. I have been in contact with Hyundai motor America and a case file has been established. " 43176412 ". Hyundai will not accept any responsibility for placing a computer in a car that will not retain a mil code. Hyundai now tells me they have done all they can and for me to get my car from the dealership and drive it. That is ridiculous. Hyundai wants me to put myself in danger of having a wreck because the car loses power in front of traffic behind me. People start slamming on brakes to keep from hitting me and blowing their horns. I'm also afraid of some loose cannon out there having road rage at me because I can't get out of the way. As for the car and Hyundai , no mention of the shortcomings of the computer was mentioned until the 3rd time the car was towed back to the dealership. Also, there is some type of serious problem with the transmission which Hyundai is failing to be concerned with . This is a dangerous situation. Do I need to be seriously injured or worse before Hyundai addresses this issue ?.

Horn stopped working.

2024 Hyundai Santa Fe VIN [xxx], June 2024 build, 62k miles. Vehicle experienced total loss of power and drive, matching NHTSA recall 24v-529 / 263 for dct failure. Dealer is refusing to perform recall, refusing to provide diagnostic codes via email, and demanding title and all service records before any work. Dealer claims new engine needed but won’t provide proof. This is a safety defect and dealer is violating recall law. " information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Cold-start hesitation & rough shifting: following the 9c2 ecu update, my vehicle is experiencing a brief period of throttle hesitation, rough shifting, or jerky transmission behavior specifically during cold-start operations.

This vehicle constantly pops up an alert to "consider taking a break" on the dash. It mutes everything else and causes a distraction. This vehicle was operated at normal highway driving conditions. There is no way to diable this. After looking online there is a reddit post from 2 years ago where this first came into effect and people have been complaining about it constantly. This is a genuine safety concern as any unexpected change or alert causes the driver to look away from the road to see "whats wrong" and for this incident nothing is wrong. An hour long commute should not pop up 15 alerts because the road has ruts or its mildly windy or the driver is wearing sunglasses or any number of minor things the vehicle doesnt like.

On August 14 2026, I drove my 2019 Hyundai Santa Fe approximately one mile from my residence to work at approximately 5:00 am. The vehicle was operating normally and I experienced no warning lights, unusual noises, odors, smoke, or other indications of a problem. I parked the vehicle in an outdoor parking lot and the vehicle remained parked and turned off for approximately four hours. At approximately 9am, I was notified that my vehicle was smoking. A person who was walking past the vehicle observed the smoke, obtained a fire extinguisher, and extinguished the fire. The fire department subsequently responded, disconnected the vehicle battery, and opened the rear of the vehicle to ventilate it. The fire and resulting heat damage were concentrated on the driver's side rear of the vehicle, directly behind the driver's-side rear tire and in the area of the rear bumper. The plastic at the base of the bumper melted, and melted bumper material was observed dripping onto the ground. The responding fire marshal inspected the vehicle and indicated that the electrical box located in this area may be associated with the origin of the fire. Wiring from this area runs to a non-original/non-Hyundai-installed trailer/tow attachment. The exact cause and origin of the fire have not yet been conclusively determined. The vehicle had otherwise operated normally during my ownership, with little to no significant problems prior to this incident. The vehicle is currently being preserved for inspection by my insurance company and mechanic. I am reporting this incident to NHTSA because the vehicle caught fire while parked and unattended after having been driven only approximately one mile, and because the suspected area of origin includes electrical components and wiring associated with the rear of the vehicle. No collision preceded the fire. There were no injuries. I am requesting that NHTSA consider this incident as a potential vehicle/electrical safety issue and investig.

My 2017 Hyundai Santa Fe, purchased new from lynnes Hyundai in February 2017, has approximately 93,000 miles. The vehicle previously developed a significant oil-consumption/engine problem that was diagnosed by Hyundai, and Hyundai replaced the engine with a remanufactured engine. Approximately two weeks after the engine replacement, the check-engine light illuminated and dtc p1326 was identified. The dealership replaced the knock sensor. Approximately two weeks later, the check-engine light illuminated again with a recurring p1326 condition. The vehicle is currently at lynnes Hyundai and has been there approximately three weeks while they attempt to determine the cause. Hyundai techline is involved. Prior to the current repair visit, while traveling approximately 60 mph, the vehicle experienced a very forceful hesitation that jerked the vehicle. I immediately slowed down and pulled onto the shoulder. The vehicle continued to hesitate intermittently while I drove slowly to safety. I was concerned that the vehicle could lose power or shut down while I was driving at highway speed, creating a risk of a crash. The recurring p1326 condition has been confirmed by the Hyundai dealership. The vehicle and engine have been inspected by Hyundai/lynnes Hyundai multiple times, including after the engine replacement. The current recurring condition has not been resolved. The check-engine light is the warning lamp associated with the current condition. I do not know the underlying cause of the recurring p1326 condition; Hyundai is currently attempting to diagnose it. The vehicle is currently available for inspection at lynnes Hyundai.

The horn has now stopped working in my vehicle twice. It was replaced 01/27/2023, and is now non-functional again. I believe this to be a safety issue as I have no way to warn other drivers or pedestrians of my presence, if necessary. One example of this, was that a vehicle was proceeding into my lane on the interstate yesterday afternoon and I had to avoid them hitting my vehicle by driving onto the shoulder of the road, as I could not use my horn to let them know they were coming into my lane while I was on the side of them.

The vehicle suffered a severe engine overheating failure that created an immediate fire risk and electrical safety signaling failure. A brand-new replacement engine was installed by an authorized dealership in April 2026 under a goodwill warranty and had only been driven ~ 3,100 miles since installation. While operating the vehicle, the air conditioning suddenly stopped functioning. Upon restarting, the check engine light illuminated; however, there was never any dashboard temperature warning indicator, notification, or chime to alert the driver to an active overheating situation. Shortly after, the engine completely disabled itself and died while in transit in a parking lot. Aaa was contacted to tow the vehicle. Smoke was visible coming out of the engine's oil dipstick and oil intake spout before being towed. After being towed home, an overwhelming chemical burning odor was noted and continued to get worse. A physical check revealed that the oil level on the dipstick was critically overfilled a full inch above the maximum fill line. The local fire department responded to the scene to mitigate the thermal risk, ordered the battery disconnected due to safety hazards, and deemed the vehicle entirely unsafe to operate or connect to power. This represents a catastrophic failure of critical safety equipment and onboard driver warning networks on a newly installed engine assembly, presenting an active safety and fire hazard to passengers. An official corporate safety case has been opened with Hyundai motor America under case number: 43112676.

The multifunction/turn signal switch in my Hyundai has failed and causes the left turn signal to operate intermittently. While driving, I am unable to reliably activate the left turn signal when making a left turn or changing lanes. The signal may fail to engage when the turn signal lever is operated, requiring repeated attempts to activate it. College station Hyundai inspected the vehicle and diagnosed the multifunction switch as the failed component requiring replacement. The replacement component has been identified as Hyundai part number 93400-s1750. I consider this a significant safety concern because the failure prevents me from reliably signaling my intention to turn or change lanes to other motorists. The malfunction occurs during normal operation of the vehicle and creates the risk that surrounding drivers will not know that I intend to turn or change lanes. The vehicle currently has approximately 86,611 miles. I reported the issue to Hyundai motor America and requested assistance because this is a safety-critical component. Hyundai declined my request because the vehicle is outside the warranty period. I am submitting this complaint because I believe the premature failure of a component necessary for the reliable operation of the vehicle's turn signals may constitute a safety-related defect, and I am requesting that NHTSA document and evaluate this failure.

My bsd sensor would go on and off for the last several months when no one was around me. I work early and even when I was alone on the road the bsd would flash for 2-3 mins and go off. . Then my fan for my air conditioner stopped. When I removed the glove compartment to see the wire connecting to the fan is "melted". When I called bob king Hyundai, I was informed there was no recall. So, I attempted to fix the issue myself only to find the fuses (under the hood) are almost all bad. The tips of the fuses will not pull out. Only the body of the fuse. With all this happening over the last several days and by the way, the vehicle passed inspection. I wanted to reach out as this is definitely a fire hazard and a huge concern.

What component or system failed or malfunctioned, and is it available for inspection upon request? the vehicle suffers from an intermittent, total engine stalling and propulsion failure. Without warning, the engine completely shuts down while driving and automatically drops the vehicle into "accessory (acc) mode". The vehicle is fully intact, operational when it restarts, and is available for immediate inspection upon request how was your safety or the safety of others put at risk? this issue has occurred five total times in live traffic, severely risking the safety of the vehicle's occupants and surrounding drivers. The most recent and dangerous incident occurred on the freeway in heavy, stop-and-go traffic. A sudden, complete loss of power on a high-speed freeway leaves the vehicle entirely vulnerable to rear-end collisions, as it leaves no room or momentum to safely coast to the shoulder. Has the problem been reproduced or confirmed by a dealer or independent service center? no. The vehicle has been brought to an authorized Hyundai dealership five separate times specifically to diagnose this exact stalling issue. Because the failure is intermittent, dealership service technicians have been unable to replicate the problem during their test drives or resolve the root cause. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? the vehicle has been inspected five separate times by authorized Hyundai dealership technicians during the service appointments mentioned above. No police, insurance, or independent manufacturer representatives have inspected the vehicle yet, as the stalling has not yet resulted in a physical crash. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear?there are absolutely no dashboard warning lights, check engine indicators, error messages, or mechanical symptoms prior to the failures. The engine shuts down instant.

With my 2024 Hyundai Santa Fe sel, at cold start the coolant gage on the digital cluster always shows 2-3 bars on the gauge and once the vehicle is put into drive (at least 30-45 seconds start up), the coolant gauze immediately increases in temperature reading without full drive (15 feet after gear placed in drive). This may be improperly reading the coolant temperature and the oem thermostat may be defective from manufacturer build. This can cause improper cooling and increase engine failure due to overheating.

Hyundai sante fe hybrid 2025 has a bad factory seal on the high voltage harness - hybrid battery connector that causes water to intrude the connector under normal conditions which can short the battery and pose a major safety issue. Hyundai is refusing warranty coverage of my shorted hybrid battery on my brand new 2025 Hyundai sante fe hybrid stating “flood” with no evidence of flood damage. My car experienced multiple p engine hybrid system faults on xxx and would not drive. I had it towed the van Hyundai carrollton on that date. They did not look at the car for over a week and it sat on their lot the entire time. On xxx they finally inspected it and claimed the car had been “flooded” and shorted the hybrid battery. The only evidence they provided was moisture in the high voltage harness. There were no water/silt lines, any other damage to any other components, and no evidence of any water anywhere else on the vehicle. The video they showed of the undercarriage only showed normal splash marks from driving. The car was never flooded/submerged. Any water/moisture found in the harness would have been due to a faulty/defective factory seal that should be impervious to water under normal operating conditions. No water/flooding/submersion damage would have been obvious of this. The dealership refused to provide any evidence and had no follow-up. One key aspect they refused to acknowledge was there was a massive rainstorm in [xxx] onxxx which was also the only rainstorm in the area in the previous 1-2 months. This happened while the car was on the dealer’s lot. The car had no issues with any water prior to being at van Hyundai. A case was opened with Hyundai corporate and the dealship also lied stating the car wasn’t in their system until xxx, which is false as I have phone records, tow records, and appointments showing the 7/10 date, so corporate overlooked that. I disagreed with the dealerships diagnosis as it was a scapegoat finding putting all blame o information redacted pursuant to the freedom of information act.

I have had the vehicle in 4 times for check forward attendition warning system light keeps coming on. The first time they replaced the front camera. The situation came back after I was using the cruise control on a express way. Did not do it do it on the road but as soon as you stopped and turned the vehicle off the vehicle check forward attention warning system would come on and off and the only way to shut it off was to stop from more than 20 minutes and it would reset. Took the vehicle back 3 times and they could replicate so there was nothing they could do. The issue came back today. The check forward attention warning system light keeps going on and off. We stopped and let the vehicle sit and upon restarting the check forward attention did not reset . This time the vehicle lost all volume from the dash board. You could recieve phone but no volume. No radio volume. All the safety features that bing are not working. Check the set up and the volume had a red ??? next to the volume. 4 times into the shop for the same issur.

For a few months- the abs light, downhill assist light, and slippery road light have all been on. Read it could be due to a bad sensor. Then on Saturday July 4th, I turned the car on and the ebrake light was on but my ebrake was not initiated. Car was making a low humming noise on front passenger side of vehicle as well. I read the ebrake light could come on due to low brake fluid, so I wanted to drive it around the block to further try and diagnose the issue. My car then made a pop noise and started smoking from where the abs pump is located and my tail lights all started flickering like christmas lights. I instantly turned the car off and disconnected the battery to prevent an electrical fire. Upon researching- there is a recall for 2015 Santa Fe’s for this exact issue except mine isn’t on the list. I need to talk to someone who has seniority upon this situation because I have called Hyundai customer service and my local dealership and nothing is being done or nobody cares to resolve this situation. My car is currently at a trusted local garage awaiting repair- I can not tow it back and forth between the garage and a dealership. I rely on my car for my children and work. . I can’t play around waiting for them to inspect it weeks from now. This is a serious issue as my children were also in the car. Everything is very similar to the recall on other 2015 Santa Fe’s. .

While driving on the on ramp to [xxx] the car completely stopped and all systems shut off. There were two dash lights that flashed quickly with one being the check engine light but I did not see the other long enough to identify it. The dealership could not reproduce the issue but has the car now and is doing a more thorough evaluation. What component or system failed or malfunctioned, and is it available for inspection upon request? the engine stopped. Yes it is available how was your safety or the safety of others put at risk? extremely dangerous as it came to a stop in the middle of the road. It was late at night so at that moment no one was behind me. Has the problem been reproduced or confirmed by a dealer or independent service center? no has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? no were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? no, the warning lights flashed on as the car died but disappeared once off.

I did a navigation update as requested by the infotainment system on the Hyundai. After the update, the air conditioner would not turn on when the ac button was depressed . I took the vehicle to my local Hyundai dealer and they found the ac blower and ac button working intermittently. After further inspection, the mechanic found the multi fuses that sit on the pcb bloc had one burnt fuse that did not blow and was still hot and the pcb block had melted around where the fuse connected to it. ( Hyundai stated that they required the damaged pcb fuse, the pcb block and the harness). I'm concerned that the electrical short discovered by the Hyundai mechanic could have progress and burnt my car or my house since I keep my car in the garage. The mechanic working for the Hyundai dealer found the burnt fuses and pcb block and kept them after replacing them with new parts. The ac was working fine until I did the navigation update and there were no warnings whatsoever.

Vehicle stalled while driving — unsafe loss of power. While driving at normal speed, the vehicle suddenly shut off without warning and the electrical system malfunctioned. I had to pull over and restart car. This created a dangerous situation and could have caused a collision. Prior to this incidenct, the vehicle had intermittent electrical issues during startup (flickering electronics). This is the first time the car has experienced during driving, and is now at the Hyundai dealership. The car has been reported as unsafe to drive. This appears similar to other Hyundai stalling/power loss issues and may indicate a developing safety defect. Requesting investigation.

The contact owns a 2025 Hyundai Santa Fe. The contact received notifications of NHTSA campaign number: 26v218000 (seat belts) and 25v659000 (electrical system); however, the parts to do the recall repairs were not yet available. The local dealer was contacted; however, the recall repairs were denied due to a lack of maintenance records with an authorized Hyundai dealer. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure.

Airbag light on. La quinta Hyundai verified light on scanned codes found active b134800 driver airbag resistance circuit short to ground 1st stage. Testing found clock spring issue internal fault. Since this clock spring is related to driver airbag, & horn, it would seem that this would be a safety hazard that would be under warranty. The extended warranty (z01) that I received from Hyundai doesn’t cover my problem.

On June 24, 2026, my spouse was operating our 2025 Hyundai Santa Fe when the vehicle suffered a sudden, catastrophic, and total electrical failure while actively on the roadway. The vehicle was stopped at a traffic light when all propulsion power was instantly lost, the engine shut down, and all electronic systems—including the center infotainment screens and instrument cluster—went completely dark. Safety hazard & entrapment incident: simultaneous with the total electrical failure, the vehicle's electronic door lock system malfunctioned. The rear passenger doors and rear liftgate locked completely and could not be disengaged or opened from the inside by the passengers. Due to this total power loss and lock failure, my young daughters were trapped in the rear seats. My spouse was forced to climb over the center console from the front seat into the rear cabin to manually extract our children through the front doors. The family had to abandon the disabled vehicle in live traffic and walk down the roadway to reach a safe location. This constitutes a severe safety hazard involving both sudden loss of motive power on a public road and occupant entrapment due to safety lock/latch failure during an electrical short. The vehicle has been towed to pohanka Hyundai of capitol heights for inspection.

I am reporting a severe safety failure on my 2014 Hyundai Santa Fe sport that perfectly matches the safety defect described in recall 21v-303 / campaign 205. This happened even though I had the dealer perform the official recall fuse fix back in 2024. The problem started after I left the car parked for about 3 to 4 hours. When I came back, I heard a motor (not the motor) loudly running under the hood even though the ignition was completely off. It stayed on even after starting and turning the car off. The battery in the vehicle had drained so bad it was deemed bad when hooked up to a tester at the auto parts store. After getting a new battery and trying to drive the car, the electrical system went haywire. The dashboard lit up with every brake warning light on, the speedometer stopped working, miles to empty being erratic, and the exterior rear brake lights kept flickering erratically after the car was turned off. The steering was acting abnormal and unnatural, not crisp and easy to turn as usual. There were absolutely no warning lights or symptoms before I parked the vehicle. I had it towed to my local Hyundai dealership, and their diagnostic scan confirmed major brake and chassis issues, specifically code c2402 for an abs pump motor circuit malfunction and codes c1200, c1203, and c1206 for a loss of wheel speed data. The vehicle has not been inspected by police or insurance representatives, but it is currently sitting at the dealership waiting for a resolution from a Hyundai customer care case manager. The 2024 recall remedy only involved dropping the fuse amperage to mitigate fire intensity; it did not replace the module housing or prevent the internal brake fluid leak from eventually destroying the system. The defect has seemingly now fully manifested, knocking out primary braking indicators and power steering assist, presenting an ongoing safety and fire hazard while driving and parked.

While driving on the highway, my 2024 Santa Fe hybrid suddenly and without warning lost propulsion power. The loss of power was immediately accompanied by multiple simultaneous warning lights across the instrument cluster, glitching and abnormal behavior of the cluster display, and then a complete electrical shutdown of the vehicle. After the shutdown, the vehicle would not restart. The failure occurred in connection with a software update on the vehicle. At the time of the incident the vehicle had approximately 12,828 miles on it. Losing motive power while traveling at highway speed created a serious crash risk, as the vehicle was unable to maintain or recover speed in moving traffic. No crash, injury, or fire resulted. The vehicle was towed to an authorized Hyundai dealer for diagnosis. I have photographs of the instrument cluster taken at the time of failure showing numerous warning indicators illuminated at once. The symptoms I experienced — progressive or sudden loss of drive power, 12-volt/charging-related faults, and failure to restart — appear consistent with charging-control and DC-to-DC converter failures that have been the subject of prior recalls and complaints on Hyundai electrified vehicles. I am filing this report to document the incident as a safety concern.

On June 20, 2026, while the 2014 Hyundai Santa Fe sport was being driven on richardson highway near mile 155 in alaska, smoke and flames developed from the engine compartment without any collision. The driver stopped and both occupants exited before the vehicle became fully engulfed. The fire created an immediate risk of serious injury or death and blocked the northbound lane. There were no known prior drivability problems, warning lamps, or other symptoms before the incident. The exact failed component is unknown. Potential areas requiring investigation include the engine, electrical system, abs/hecu brake module, multi-fuse, fuel system, and other engine-compartment components. Alaska department of public safety responded. Its report states that there was no obvious cause, but that the fire appeared to have originated in the engine compartment. The vehicle was towed and preserved for the manufacturer. Hyundai inspected the vehicle and confirmed that the inspection was completed on July 11, 2026. Hyundai later stated orally that it did not find an engine defect, but it has not provided the complete inspection report, testing methods, photographs, technical findings, or a written origin-and-cause determination. Hyundai has not explained whether the abs/hecu, electrical system, multi-fuse, fuel system, or other potential fire sources were separately examined. The vehicle sustained catastrophic damage and was a total loss. Both occupants escaped, but experienced severe ongoing psychological distress after the fire. I request that NHTSA evaluate whether the fire involved an engine, electrical, abs/hecu, fuel-system, recall-remedy, or other safety defect. The vehicle was available for Hyundai's inspection. Its current availability for further inspection is unknown. The vehicle remains preserved and is currently available for further inspection upon request.

In June 2026 I took my vehicle to Hyundai for a recall to the ecm module. After that my vehicle would lose power and hesitate to shift gears, and overall does not feel safe. Took vehicle back to dealer and they have told me that I have to wait for them to issue a recall fix for this now .

See attached document for complaint.
