Electrical System Problems of Hyundai Santa Fe - part 2

Vehicle killed the battery even with new alternator and new battery. Dealership does not know why and it died while at the shop. Vehicle has extremely high oil consumption and light comes on every once in a while. Vehicle started shaking and took to two dealership. Vehicle was diagnosed with a burnt valve in cylinder one. Dealer stated they have not heard of this problem. Called Hyundai representative corporate and was told they never had this problem before and have not heard of it. Out of warranty and was informed I would have to pay for it even though it is common in these vehicles.

Frequent intermittent dash warning lights, no speed indicated, no tach indicated, cycles through warnings of safety systems malfunctioning. No lane departure, no adaptive cruise, no cruise, no forward collision warning, no blind spot warning. The disabling of these systems puts all drivers at risk. Dealership replaced front camera and windshield to fix this issue. Not fixed, continues to alarm at random times while driving.

Horn failure, confirmed by Hyundai dealership. No warning or indication of failure. Went to use horn in a safety situation when I needed it, and it was non-functional. A huge safety risk for myself and other drivers on the road. In doing research, this is a known manufacturer defect, with most owners having to replace low and high horns multiple times due to failure. The horn units apparently due to placement and design fill up with water, which leads to failure, again, without warning.

I am reporting an urgent request immediate action regarding a serious unresolved, recurring public safety issue with my vehicle. It is potentially the fault of alexandria Hyundai's service department (in alexandria, va) who had just serviced my vehicle for what should have been a routine servicing (on may 7). My car had a catastrophic and complete failure on a high speed highway (the car quickly decelerated) which represented an incredibly danger situation for myself and other drivers on the road. My car was purchased in 2023 and has 15,241 miles. It has been perfectly maintained. On [xxx], I was returning to my home in virginia from maryland on an 8 lane highway with a 55mph speed limit when I had a very dangerous complete failure of my car. Simultaneously, the car started bucking back, the speed was decelerating regardless of my pressing the accelerator to keep my speed the same as traffic, and I received a flashing large red message that said "check hybrid system - stop safely. " fortunately I was in the far right lane and was able to veer it over to a narrow shoulder. It was 8pm and getting dark. After a short while, the car lost all power so I was on a narrow shoulder with no lights flashing anymore. I was in this dark car with a lot of traffic speeding my with my 2 dogs. I became incredibly stressed about how we were going to get home. I contacted aaa, a police officer and uber pet who worked together in this unsafe situation on the side of the highway to get myself and my dogs home into the uber vehicle with only the front door opening (no power). It was over 2 hours before I was home safely it was incredibly stressful situation. The car was towed to alexandria Hyundai and they dismissed the issue and fixed nothing. I contacted Hyundai customer service and asked for escalation and they have done nothing. I am restricted in my driving because of the severe safety risk but had to drive again on [xxx] and it occurred again on a highway information redacted pursuant to the freedom of information act (foia), 5 u.

The horn has failed and been replaced 2 times after purchasing from brand-new. It has failed again but the vehicle is now out of warranty.

I am writing to express my concern regarding an ongoing and persistent issue with excessive engine oil consumption in my 2015 Hyundai Santa Fe, subject: severe oil consumption issue - 2015 Hyundai Santa Fe - VIN: 5xyzwdla1fg238718 the vehicle consumes an alarming amount of oil, approximately 1 quart every 300 miles. This rate of consumption is far beyond what is considered normal and strongly suggests a serious mechanical or manufacturing defect. I have already taken the vehicle to a mechanic to diagnose and attempt to resolve this problem. Based on their professional advice, the following parts were recently replaced: 1. Engine valve cover gasket 2. Turbo charger oil line 3. Spark plugs unfortunately, despite these repairs, the issue of excessive oil consumption remains unresolved. The rate of oil loss remains consistent and dangerously high. This was first informed by a service center when I took the car for a random check. Then, after traveling 1,000 miles, the engine oil level dropped again. After that, I am keeping an eye on that. This level of oil consumption poses a significant risk to the engine's long-term health and reliability, and it is a major inconvenience and expense for me as the owner. I am deeply concerned that a major engine component may be failing.

I own a 2014 Hyundai Santa Fe sport 2. 0t which has had door latch issues.   recently, the front passenger side door latch needed to be fully replaced due to a failure which caused the door to be loose latching and the latch sensor always showing open.   I paid out-out-pocked for this repair as the Hyundai dealership said there are models which this exact issue was identified, but they said the parts extension had not been placed for my exact vehicle.   they were also confused as to why this was not being covered as they see so many of these same repairs. Now, less than one month later, the front driver's side door is now experiencing lock issues in which a loud grinding noise is occurring when the vehicle attempts to lock or unlock the door.   additionally, the door does not unlock some of the time from the external and the manual door handle on the interior is getting harder and harder to open.   both of these issues are consistent with other recalls for other Hyundai models and consistent with the door latch module and actuator failure.   I would like to file a complaint regarding this issue as it seems to be a common issue with Hyundai models using this door latch module.   I believe the parts extension and repairs for these door latches should be covered by Hyundai especially as this becomes a large safety issue with driving the vehicle with concerns of door latch stability and security.

The car loses power. The battery and key ignition light keep coming on. A message displays auto engine off. Please shift to n or p and start engine manually. After communicating and showing video proof of the incident, the dealership replaced the alternator and battery. The issues started around 5000 miles. The infotainment system lags and the car lags. Sometimes I am left on the road because the case refuses to cut on or off.

Car did dashboard update on 4/10/25. Had less than 4300 miles. Unable to unlock car due to dead battery. Car unlock service opened door for tow company to jump battery and advise that the new 2025 Santa Fe hybrid battery needs to be replaced. May need other service (alternator or hybrid battery too) but the 12v battery had been drained. Interior lights would not turn on prior to this happening.

Loss of acceleration and stuttering when I was trying to get up to speed on the interstate going up a hill. Instantly blinking check engine light. Won't go above 2000rpm or 60mph. P1326 code read glow relay short circuit.

The reverse camera system did not come on when reversing. It could lead to someone like a child getting hurt if they’re walking behind the vehicle. The problem was reproduced by the dealer and serviced for this issue. They confirmed it was the same problem as the recall. There is a recall for 2022 Hyundai Santa Fe’s that were manufactured in the alabama plant. This is where my car was manufactured. For some reason, it was not included in the vins that were recalled.

Vehicle will not change out of ev electric mode and return to gas power causing hybrid battery drains to zero, vehicle loses acceleration, you can push the gas pedal to the floor and you have no acceleration, very unsafe when you are in traffic, no power to maneuver or avoid other vehicles quickly if needed, potential for accidents, hybrid system warning lights and alarms go on, have to try and pull over safely, battery will not recharge or takes a very long time to do so, only recourse is to shut vehicle off and restart which seems to reset vehicle, which in turn does not leave any warning lights other than codes on to show dealer, very dangerous to lose all acceleration capacity while in traffic, this has happened multiple times with the latest being today 3/23/25, vehicle is available for you to inspect, have had other powertrain codes issues as well, dealer has replaced fuel pump and erg valve but it does not resolve this hybrid issue, this battery drain issue has occurred multiple times but no resolution, help!.

My steering would work while I was driving with my kids in the car, my breaks were barely working, the hood started smoking and something under the hood in the engine caught on fire, there was a horrible smell when I was breaking and the breaks would jolt. The engine and cooling was not turning off even with my key taken out, the fan engine was running nonstop no matter what, smoking etc.

The contact owns a 2017 Hyundai Santa Fe. The contact stated that the automatic power door locks failed to operate as needed. Due to the failure, the contact had to manually unlock and lock all doors inside the vehicle. In addition, the contact stated that the button to unlock the gas cap also failed to operate as needed. The vehicle was not yet diagnosed or repaired. Neither the dealer nor the manufacturer were notified of the failure. The failure mileage was approximately 72,000.

12v battery discharges and SUV has to be junp started. Hyundai removed the battery reset button that existed until 2023 model year. Manufacturer should do recall to change the 12v battery charging characteristics for 2024/2025 model years.

12v connector for phone charger melted my phone cord. Reported to centennial Hyundai las vegas and high desert Hyundai kingman az. Both service departments said my vehicle cannot detect the problem because I purchased a substandard plug-in. I have worked as an operator of high voltage electrical systems. I understand in some circumstances that a system cannot detect a fault, however the company is still responsible for the fire it caused. This is unsafe and can cause serious consequences. It must be corrected.

Our vehicle continues to experience loss of power driving , on cold days below freezing. When driving normally this hybrid vehicle will be in hybrid mode at a stop, then when accelerating, the ice engine will not start to assist the hybrid, causing a bare minimum of power to be available, just enough to pull over. On several occasions this has led to very near rear end collisions from the driver's behind. So far I've been able to avoid injury, as I recognize the condition and am hyper attentive to its possible happening. The vehicle handed shown any check engine warnings until yesterday. As it was dying I pumped the accelerator to see if it would go, latching a tps out of range code. The condition has been brought to Hyundai corporate and dealerships with no repair, and no resolution, they say it's fine. This is well documented by others driving Santa Fe hybrids, and tucson hybrids on forums. No one fix has been established, with some dealerships replacing parts, and others no work being done because their scan tool sees nothing. With dozens of recalls for minor inconvenience issues, I do not understand why a recall for this drivability safety issue has not been mandated! these vehicles are defective, and potentially very dangerous. Loss of power, acceleration when others are behind you anticipating you to go, is a real serious danger, not to mention you being stranded in frigid weather. This began happening at 23k miles and continues today with 48k miles on mine. If the vehicle is shut off, then restarted, it is again drivable, until the next happening. One reason Hyundai, says nothing's wrong, and often blames the owners. I can't be without a vehicle, and Hyundai has washed their hands on this, so I'm stuck Hyundai must be forced into an investigation, and a safety recall on this or nothing will be done. How many accidents or deaths are required to get a recall accomplished?.

Every time it rains, one of the dual tone horns will fail. I have had the horn replaced 2 times. I am beginning to have a problem with the horn again after this last rain. It is a matter of time before it fails completely after a rain and becomes unusable. I feel this is a significant warning feature that must be reliable.

The contact owns a 2017 Hyundai Santa Fe. The contact stated while her husband was driving at approximately 65 mph he heard an abnormal banging sound. The contact stated that her husband said that the sun roof had shattered. The contact stated that her husband had not had highway debris or a stone strike the sun roof. The contact stated that her husband had not noticed any warning lights. Additionally, the contact stated there were multiple electrical failures with the vehicle. The contact stated that the cruise control was not functioning, the tail gate was opening independently. The contact stated that the electrical failures were constant. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that there were no electrical failures and were ordering a new sun roof. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 53,000.

The engine locked down due to the improper power train, driveline, driveshaft. Oil leaking and malfunction of power train, driveline, driveshaft caused motor to knock and lock down.

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.

Between [xxx] am on [xxx]. I powered on my vehicle and the rear trunk door simultaneously opened. As I was driving my son to school that morning, I noticed water dripping onto my foot. I continued to drive but was distracted by beeping and warning messages but because the dashboard display was constantly switching from daytime to night lighting I could not readily see the dashboard. I tried to manually adjust the light by turning the knob off "auto" and also turning lights to "off" but it would immediately switch back. I made it to the first stop light and while stopped I was able to observe water droplets on the front panel of the interior fuse box. I pulled open the panel and water dropped out onto to floor. I replaced the panel. I continued to drive but was panicked and worried that water was in the fuse panel area. I arrived at my son's school and left the car running as he was dropped off. On the drive home, the beeping continued. This time, I saw the warning message about vehicle in my blind spot but I was on the street corner about to make a right turn and there was no vehicle next to me! the lights also kept switching as before. There was rust observed in the fuse panel area. When I got home, I called the dealership to inform them what happened. They refused to give me a loaner. I told them that water intrusion should not have occurred (we had severe weather and heavy rains the day prior) and now my car was having electrical issues and I was concerned for my safety and the safety of driving my 3 young children in car seats should there be an electrical fire. I mentioned the recall on my vehicle for water accumulation in the tow hitch and risk of electrical fire. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The forward attention warning at times alarms constantly, even though I am looking forward. It is highly distracting as it alarms many times per minute. A menu option exists in the settings to disable it, but that doesn't work. I have read online that this is a common problem with 2024 and 2025 Hyundai Santa Fe models.

When you stop the car , you cannot lock- unlock the car with keyfob. Nothing happens when you press these buttons on keyfob. And media screen inside the car is still on. But the car is off for sure. After few minutes only, keyfob works fine and you can lock-unlock, remote start etc. So for 5 minutes, you cannot do anything like locking the car, which is a safety hazard.

The backup camera will sometimes have black lines and flash off/on while in reverse. Other times, it will display a solid blue screen and the camera doesn't show an image at all. I took it to the dealer and since they weren't able to replicate the problem, they didn't look at it. I showed them a video I recorded, but that wasn't good enough. It's happening more often and seems to mostly occur after the vehicle has been parked outside.

Engine has always burned oil and vehicle only has 72,000 miles on it. Leaking black liquid/oil out exhaust pipe, blowing out black clouds of smoke and have to keep adding oil. Whole rear end had to be replaced, timing chain and cover replaced, ac unit replaced, rear camera replaced, climate controls change settings by them selves, leaking gaskets, all this and more has been going on with this vehicle when it only had 35,000 miles on it. Front suspension creaks for years. No way a vehicle should have all these issues with low mileage and has been very well cared for!.

Headed to my work ,outside temp 26 deg f, when on hiway entrance ramp, vehicle lost all acceleration. Vehicle is a hybrid, condition no warning lights on dash, vehicle was stuck in ev mode, which the ice engine would not start to help as normally would do. Hybrid battery began draining very quickly. There was a semi truck right behind me accelerating hard to get on highway . This time I managed to pull over on the debris filled shoulder before the system fully shut down as it has done before with the warning ?? hybrid system failure, pull over now ! and loud alarm going off. This is a serious loss of total motive power, which I've reported to Hyundai corporate, and dealerships for repair before, to which they say " we can't duplicate, all systems are fine", and blame me for the problem. Hyundai has washed their hands of this dangerous situation and won't help me. This is the 5th occasion of this problem, I now know from my experience and reading Hyundai forums this issue is wide spread among Hyundai tucson and Santa Fe hybrids, with some places replacing parts, that doesn't fix the issue. I know how to react by pulling over immediately, shut off the vehicle completely, wait. . . Then restart the vehicle, and so far ,it will drive normal with no codes or warnings after that, until the next random occasion it happens. This is extremely dangerous in cold weather and around other traffic posing a major collision hazard and stranding someone who knows less about this condition. Hundreds have reported this as per the forums, yet no recall or TSB or real fix has been issued by Hyundai.

1. Abs module stopped working. Car no longer has abs. Will not cover under warranty due to computer component. 2. Engine burns oil. 3 quarts in 1k miles. Combustion cleaning done. Now engine light is one, oil light comes on, car smells of gas & oil.

Driving along, merging onto interstate, various warnings such as check lane keeping assist, and warnings to stop vehicle and check brake systems. Driving approximately 50mph, the warning started to flash and speedometer dropped to zero then went back to full speed. Automatic braking was attempting to slow the car. Attached photo shows an indicated speed of 0mph, however was travelling approximately 50mph at this time. I also have video of the errors occurring, but there is not a way to upload video.

Horns stopped working. Consider this to be a safety issue for obvious reasons. Checked horn fuse and it was not blown. Contacted local dealer to have it repaired. Awaiting an appointment.

While driving, the vehicle lost its brakes and rolled to a stop on [xxx] at that point the vehicle compartment began to fill up with black smoke and soot and flames started to come out of vents. My daughter immediately grabbed her dog and exited from the vehicle to a safe spot away from the car. Within 10 seconds the vehicle exploded and erupted into a 20 ft fireball. If my daughter would have hesitated she could have been killed. Hyundai inspected the vehicle and found nothing conclusive except that this problem has been documented in other incidents. The vehicle was declared to be totaled. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The integrated thermal monitor is stuck. When I took it to ken vance Hyundai today, they said it is a common issue and if left unfixed. It would blow the engine.

I have a 2022 Santa Fe xrt within the 1st yr of owing in 2022 the horn stopped working in the winter. Went to dealership told it was known issue they replaced it. A few months later into following year still winter went out again they fixed again stating my car has 2 horns and both failed. So far 2022 and 2023 2 times. Fast forward to earlier in 2024 beginning of year horn failed again took to dealer expressed my concern of this is a safety and inconvenience issue they apologized but no recall yet. Now it's almost 2025 and I will be taking my car back to the dealership this weekend for yet another time due to the horn not working at all. I've found out my horn has not worked due to driving and a vehicle almost colliding into my lane and went to honk horn and nothing. A separate time a person has cut out in front of me almost causing an accident and all I could do is to lock up my breaks and swerve hope they see me and don't get hit could not beep to warn them. I bought the car brand new in 2022 Feb and I have had the horn replaced 4 to 5 times and they still are staying no recall this is ridiculous.

Vehicle fails to appropriately recognize when it is put in park. The dash shows a "p" indicating the vehicle is in park, but emits a continuous beeping sound with a message on the dash that reads, "auto stop is off. Shift to p or n and start engine manually. " however, when pressing "p" as it states I must do, it then reads, "gear already selected," before returning to the previous message. This is all while a "p" is illuminated and beeping is continuous. Throughout this time, if the brake is released, the car begins driving forward as though it is in drive, not park. I have 3 separate videos of this happening. To answer the above questions: the vehicle has repeatedly been inspected by a Hyundai dealership and each time I am told the issue cannot be replicated. I am happy to have it inspected again. It most certainly puts my safety and others at risk as it continues driving after I have engaged park. No police or insurance representatives have yet inspected it. No others warnings or messages appear before it occurs, only during. The issue first started just before 5k miles on the car and has since occurred at least 5 more times.

The contact owns a 2019 Hyundai Santa Fe xl. The contact stated that there were intermittent, but constant electrical failures with the vehicle. The contact stated that the doors unintendedly locked and unlocked. Additionally, the contact was unable to upload the software updates for the vehicle or connect the vehicle to the emergency 9-1-1 system through the cell phone. The contact stated that the check engine warning light was intermittently illuminated. The contact had taken the vehicle to a local dealer to be diagnosed; however, the dealer was unable to find an electrical or computer failure. The vehicle was not repaired. The manufacturer was informed of the failure but was unable to assist the contact. The contact believed that the computer system had been compromised. The failure mileage was approximately 75,000.
