2020 Hyundai Santa Fe Complaint Log

Car was burning a significant amount of oil in between oil changes. The driving down the highway the car started missing and almost stalled out at 60 mph almost causing a accident now vehicle will not run properly and is blowing black smoke out of the tailpipe

The front piece of the panoramic sunroof spontaneously shattered while sitting in my parked vehicle. I heard a loud pop and saw that the entire piece of glass was totally shattered. I took it to the dealership and they told me it is a known problem with this type of sunroof on their vehicles, they said it is not covered by warranty. The estimated repair cost was over $800. Had I been driving down the road with the sunroof open, it could have presented serious safety risks.

I believe I am having an oil burning/consumption problem. I drove my car and the oil light flashed and I have had some hesitations in the engine. I checked the oil upon parking at my home and I had no oil on the dipstick. I put in approx 4.5 qts of oil. I read online that there is an oil consumption issue with my engine type (2.4 gdi). I called Hyundai Service Dept at my local dealership and they told me before looking at the car that wasnt an issue and not the problem. They investigated and found 0 leaks or issues with the car and engine. We did an oil change and they told me to come back in 1k miles. Im very close to the 1k miles and my dipstick is showing low level of oil. The dealership is not happy that I called today to tell them this and said just come in once you hit the 1k and no sooner. I have been told that the next test that needs to be done will be between 700 and 800 dollars out of my pocket as "Hyundai doesnt like to cover the tests and neither does the extended warranty." This appears to be a bigger issue than what Hyundai wants to acknowledge. I have no confidence in them fixing the car and debating to trade my sante fe in and getting a new car at this point.

Engine oil disappear at 2,000 miles. Car dead stop while driving without any warning ️ break fails at 95 degrees curves. Steering wheel loose and make noise. Hyundai dealer refused to fix the issue.

I was backing out of a parking spot and suddenly the car accelerated backwards into a wall. The floor mat was NOT on the accelerator pedal. Obviously, I might have accidently pressed the gas pedal. But, I strongly believe I did not. For me to be mistaken, all three of the following would have to be true: 1) I would have had to put my foot on the accelerator by mistake, even though I am of sound mind and body, I was not distracted, and I have been driving for decades without having done such a thing. 2) I would have had to continue holding my foot to the gas pedal even as I felt myself racing backwards. 3) Having slammed into the wall, I would have had to be unaware that I had caused the accident. That all three conditions were true seems highly unlikely. (Not impossible. Just unlikely.) I can't imagine stepping on the gas when I meant to step on the brake and then not realizing that I was doing so and then not remembering that I had done so. Cars have computers and computers sometimes have bugs. It seems more likely that a computer glitch caused the crash. And, I suspect that, if it has happened to others, they did not report it because they assume they would not be believed. (When I told a friend of mine what had happened, he told me that, on two separate occasions, he applied the brakes on his Hyundai (a different model) only to have the engine rev up and "fight" his braking. He had to press harder on the brakes to stop his vehicle.) Question: does the onboard computer record all of the car's and computer's activities? (Note: I called the police, who came to document what had happened. I don't believe he filed an official report, but if you need what he recorded, let me know.)

The airbag light comes on intermittently when a passenger is sitting in the front seat. Took to a LaCrosse WI Hyundai dealer for OBD code. The dealer reported the following: “Body Elect Concern. ODS ECU and Seat Mat Failure. Inspected found code b149000 found code due to ECU failure. Tested seat mat and found mat also failed due to high resistance outside of spec range. Repair estimate given at $2,800.00.

I am writing to formally express my serious concerns regarding an ongoing safety issue with a certified used vehicle I purchased from McDonough Hyundai, [XXX] , in December 2024 and the dealership’s repeated failure to resolve the issue, even after a car accident occurred due to this malfunction. Two months after purchase, I discovered that my horn did not work when I attempted to use it. I brought the vehicle back for service and was told the issue had been resolved. However, the horn continued to malfunction. I have returned to the dealership approximately five times with the same complaint. Each time, I was told the horn works, yet it continues to fail intermittently. In June 2025, I was involved in a car accident and was unable to alert the other driver because the horn did not work. Despite the severity of the situation, no one at the dealership has taken appropriate action to identify or correct the issue. During my most recent visit, Service Manager [XXX] witnessed firsthand that the horn did not work. His technician pressed it once, and because it worked in that moment, the vehicle was returned to me without further inspection. This intermittent failure has still not been addressed. I have time-stamped video evidence showing the horn failing just two days after the last service visit. A non-working horn is a major safety hazard. The repeated dismissal of this issue is unacceptable. I expected better from a pre certified used vehicle. I would be happy to provide any information needed to resolve this issue. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

High utilization of motor oil. Using 1 quart of oil every 300miles. Hyundai dealership (Gurnee Hyundai-Illinois) completed a "combustion system cleaning" but oil consumption continues unabated. Getting run-around from dealership and manufacturer. I am original owner. Care has 87K miles.

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.

Front passenger seat belt will no longer click and lock into place. When held in place by hand, the warning lamp turns off and the audible warning alert turns off. It has not yet been checked by any service department.

PASSENGER AIR BAG WARNING LIGHT COMES ON WHILE DRIVING WITH A PASSENGER SITTING IN THE FRONT PASSENGER SEAT.

2020 Santa Fe. Engine is consuming oil exceding average rate of 1 quart / 1000 miles. No smoke, no external leaks. No warning until car begins to shudder while driving.

Check engine light began flashing suddenly as I was driving. My vehicle went into limp mode on the interstate in 70 mph traffic, it was dark and pouring down rain. The check engine light was no longer flashing when I went the next day to take to the dealership to be checked. They stated nothing can be done unless it is flashing when I bring it in. This is the 3rd time it has happened in this vehicle, and I have taken in on other occasions with no resolution. This puts my family and I at risk. This appears to have same issues as my previous vehicle a 2014 sonata limited 2.0t.

First of all the transmission locked up at 97,423 miles when I was on my way to work. It took almost a month to get this fixed under warranty. I bought the vehicle in 2021 with 55 miles on it. Now at 164,000 it has to have a new motor. It has burnt more than a quart of oil every week for the last 2 years. I have had it to the dealership multiple times to be checked and never got a response as to why it was burning oil. Then in December of 2024 I was on my way to work and the vehicle was struggling to go. I would push the gas and it would go a little but as soon as I let off the gas it would stop running. Took it to the mechanic recently (due to other issues) and was told that it is only running on 3 cylinders. Also that in order for it to stop burning 2 quarts of oil a week that the pistons needed replaced. Mechanic stated it would be cheaper and better with the other issue to replace the whole motor.

The contact owned a 2020 Hyundai Santa FE. The contact stated that after the vehicle was unoccupied and parked in the residential carport, she was in bed for the night and four bystanders stopped outside the contact's residence. One bystander knocked on the contact's door, the second bystander ran to the back of the house to search for a rear entrance to enter the home and the third bystander grabbed the water hose and attempted to extinguish the fire but was unsuccessful. The contact mentioned the parts of the vehicle exploded. The fourth bystander called 911 and the contact evacuated from the home. The contact did not sustain injuries. The contact mentioned the bystanders did not sustain injuries either. No medical attention was sought. No police report was filed. The fire departments arrived on the scene, and the firefighters extinguished the fire. The fire consumed the vehicle in the carport and the fire spread to the house causing damage. Fire department reports were filed but no report number was available. The vehicle currently remained on the scene. The insurance company deemed the vehicle and her home totaled. The manufacturer was made aware of the failure and an inspector from Progressive Insurance in addition to an inspector from American Modern Home Insurance out to the contact's residence after careful review they could not discover a product defect responsible for the vehicle incident. The failure mileage was 61,000.

To Whom It May Concern, I am writing to formally report repeated safety system failures in my Hyundai vehicle that have resulted in significant injury and ongoing hardship. The first incident occurred in 2021, when my vehicle was struck from the front by another driver who fled the scene. Despite the impact causing visible front-end damage, the airbags did not deploy, and the seatbelt did not engage properly. The vehicle was repaired by an authorized Hyundai dealership, yet at no point was I informed that the vehicle’s safety systems might be compromised or that it should not be driven. The second and more severe incident occurred in December 2024, when my vehicle was rear-ended by a commercial truck and subsequently pushed into four other vehicles. Once again, neither the airbags deployed nor the seatbelt engaged, resulting in multiple bodily injuries for which I am still undergoing treatment. After reporting this second failure to Hyundai, I was informed that the airbags and seatbelts may not activate when the vehicle is struck from behind. However, this explanation does not address the fact that the same safety failures occurred in the 2021 front-end collision as well. I believe these repeated malfunctions indicate a serious defect in the vehicle’s safety restraint and airbag systems that poses an ongoing danger to drivers and passengers. I am requesting a full investigation into these safety system failures, including whether the dealership’s repair process or Hyundai’s design or manufacturing contributed to these malfunctions. Due to these failures, I have experienced significant physical injury, emotional trauma, and ongoing medical issues, and I am seeking appropriate accountability and resolution.

Change the oil in the engine and found metal flakes in the oil. Took it to the dealership and they stated this is normal. After going to another dealership they found that this was not normal and had to replace the motor. Now three (3) months later the check engine light is flashing. It has a code of P1326. Was told this could be a knock sensor or it could be something wrong ever further into the engine.

While driving down the highway my car started slowing down and would not accelerate. All the lights came up on the dash board and would not let me accelerate. I had to merge 2 lanes to the shoulder on a busy highway where my car ended up dying and would not turn over. I was concerned for my safety and the speed limit was 70MPH and my car rapidly went down. After 5 minutes my car came back on and then immediately stopped working again. I had my car towed to the local Hyundai dealer where they said I would need a new engine on a 4 year old car. My make and model are in the recall for engine issues but my VIN # was not included. I spoke to Hyundai a few times and they stated there was nothing they can do and we needed to pay for the new engine.

The vehicle seat caught fire overnight, Sept 26th, and was discovered the morning of Sept 27th 2024. The fire was contained to inside the vehicle and melted parts of the driver seat and lower part of steering wheel. The vehicle interior was covered in orange dust and had extremely toxic smell inside. Insurance 3rd party inspected and declared it a total loss. A few weeks later, a neighbor and fellow Hyundai SantaFe owner mentioned that he had heard of an issue with the Santa Fe catching fire. With this new information, I called Hyundai to alert them. Hyundai opened an investigation, but closed the claim since the 3rd party that declared it a total loss had already sold it as salvage. They also denied any recalls pertaining to my specific vehicle or knowledge that electrical fire was a potential issue for this model and year. There was a recall for a tow hitch that lead to fires....but mine did not have a tow hitch. Obvious concern is that this could be a wider issue than just 1 vehicle and lives and property of those owners and others could be at significant risk.

The contact owns a 2020 Hyundai Santa Fe. The contact stated while driving at higher speeds, the vehicle experienced a momentary loss of motive power. The check engine warning light was illuminated. An unknown local dealer was contacted, but the vehicle was not diagnosed or repaired due to the cost. The contact stated that prior to the failure, the vehicle was taken to Auto Zone where a diagnostic scanner was used to diagnose the vehicle. The contact was informed that the MAP sensor had failed and needed to be replaced. The vehicle was taken to Advance Auto Parts where, the DTC code: P2565; was retrieved. The contact stated that the spark plugs, and the MAP sensor were previously replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 100,363.

Knock sensor failed while it was raining and at highway speed and caused the vehicle to slow and jerk. After further investigation this has been a recall issue for several years , but Hyundai still has a problem with their Knock sensor and no recall on the 2020 Santa Fe

I parked my 2020 Hyundai Santa Fe in a hospital parking garage on the morning of July 30, 2024. I was getting ready to leave after my doctor’s appointment. I slowly reversed my car and hit a pillar behind me. As I put the car into drive to come forward slowly, the car accelerated forward at a very fast speed. I took my foot off of the gas and kept pressing the brake pedal, but the car kept speeding forward on its own and I crashed headfirst into a concrete wall. The impact cracked the concrete barrier on the outside of the parking garage. The air bags deployed, causing fractures in my sternum and L1 vertebrae. This accident occurred near the elevators/stairs and cars were all around. IF a person had been walking in my path to get to their car, he/she would have been severely hurt or killed. I was able to frantically steer the accelerating car into a handicap parking space and crash into the concrete wall, thus avoiding other cars. If that space was not available, my car could have crashed into another car with people inside. We were just told that the car is going to be totaled. If necessary, it could be inspected before that happens. I thought that I was going to die… the car was out of control. I do not want this to happen to others with this type of car…or put others in its path at risk.

I was driving on the highway going about 75 to 80. My vehicle will start warning me that a car was in front of me when the cars was about 3 to 4 car links ahead of me. The emergency brake will start for at least a mile down the road. Then shut off. It will happen at least 5 times on a 4 hour trip. This really need to be fix before someone get rear end.

The contact owns a 2020 Hyundai Santa Fe. The contact stated that occasionally while driving at various speeds in hot climate, the air conditioning failed to blow cold air. No warning light was illuminated. The vehicle was taken to a local dealer however, the failure could not be replicated. The vehicle was taken to a local independent mechanic for a second opinion, where it was diagnosed with an evaporator temperature sensor failure. The contact was informed that the evaporator temperature sensor needed to be replaced. The vehicle was not repaired. Upon further investigation, the contact related the failure to Technical Service Bulletin: 21-HA-001H; however, the VIN was not included. The manufacturer was made aware of the failure. The failure mileage was approximately 29,000.

The park break keeps turning on by its self, rather I'm driving or sitting at a light or stopped at a stop sign. Putting me and my passengers as well as the other motorist on the road at risk for collision.There is an orange EPB light that never goes off that came on about two months ago, and the emergency park break started being engaged without me engaging it after last driving the car, every time I get back in the car. A red park break light comes on and continously blinks and that has been happening for the last month and a half. The breaks lock and I have to keep pushing the park break disengage button and turning the car off several times to get it to disengage at some point, while in traffic. I haven't had this problem checked out yet, because it is so costly, but I plan to.

Twice while driving in traffic my vehicle’s engine randomly shut off. This left me in very unsafe conditons as one as at a busy intersection which resulted in cars going around me while I attempted to restart my vehicle. The problem hasn’t been reproduced by a dealership. The vehicle hasn’t been inspected. No warning lights or dtc. First failure was 6ish weeks ago.

Front drivers side wheelwell cover come off on the highway, I could have had a wreck

On Interstate 95 in Virginia, multiple times, going ~68-70 MPH the vehicle automatically applied the brakes causing an unsafe situation with a momentary loss of control. Multiple times this has happened with no other vehicle or obstacle in front of, or beside me. It has happened now for no reason causing the loss of control of the vehicle. We have reported this to Hyundai and they cannot find any fault code, or record of the incident. Our understanding is that this is a widespread problem with this vehicle and system, but also includes other vehicles with the same technology. We are afraid this may end up causing serious damage, injuries or fatality(ies). We have asked Hyundai to turn the system off, and they have refused. They have no solution, and we have spent time and money on this.

While driving on the highway loss of power and all the light on the info area lit up had to pull over on shoulder and shut off car and restart. And on two separate occasion while on low speed local road brake pedal locked up and I could not stop the car using the brake it was like it was press down already and I was unable to stop.

Prior to these occasions, the Hyundai Santa Fe was constantly needing oil added. On top of that, starting on [XXX], my 2020 Hyundai Santa Fe coded with a check engine light blinking in the upper right corner of the dashboard. I was on [XXX] in NW Indiana on my way to a meeting. The SUV would not accelerate past 2,000 rpm and bogged down on a national interstate sending me into a panic. I had my car towed back to my house. I called my brother in law, [XXX] , who sold me the vehicle in November 2020, to get advice on what to do next. I was told to have the vehicle towed to the nearest dealership. After having my car sit there for two weeks, Webb Hyundai finally looked at it. They upgraded the knock sensor software and had the knock sensor replaced. With the plethora of things that I asked to be repaired or looked at, they only fixed the knock sensor. Due to an extended warranty, I paid $100. Two days later, the SUV got a flat tire. The SUV sat for a week or week and a half due to a flat tire and the place not having it in stock. [XXX] driving back from getting my new tire put on in Valparaiso, Indiana, the vehicle coded again on [XXX]. It caused another very dangerous situation as the vehicle slows to 2,000 rpms. Once again, I had the SUV towed back to my home in Cedar Lake, Indiana. It sat for a few days while I was deciding my next move. This time, I had the vehicle towed to Gerald Hyundai, where my brother in law works and where the vehicle was originally purchased. The vehicle arrived [XXX], 2024. The SUV only sat for one day before telling me all the work that needed to be done. Some of the charges were covered by the extended warranty. Total bill was $540. The work was done on May 13, 2024. I could not pick up the vehicle until the weekend. However, my other car was in an accident, so I did not make it until [XXX] 2024. Shortly after picking up my vehicle, the SUV coded again on [XXX] going back to Indiana. More to follow.. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2020 Hyundai Santa Fe. The contact stated that while driving at an undisclosed speed and attempting to accelerate, the vehicle suddenly lost motive power. The check engine warning light was illuminated. The vehicle was taken to the dealer, who determined that one bolt on the fuel pump was sheared off and another was extremely loose. The vehicle was repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 63,000.

Sunroof spontaneously exploded while driving on the highway. There were no other vehicles around and nothing visibly seen that hit the roof.

I purchased this vehicle in early 2023. I was driving on the interstate and received a TINY rock chip that immediately cracked across my entire windshield in April of 2023 resulting in my replacing the windshield. I have since received two TINY rock chips one on 11/25/23 and one on 01/03/24 resulting in immediate cracks. the rock chips are barely visible and as soon as it was heard each time, the windshield cracked considerably. The windshield is faulty and defective. I have driven the same interstate for the last 10 years and have never had this issue with any other vehicle.

My engine light came on December of 2022. I took it to Autozone and had them to a diagnostic text to read the code. They stated it was a misfire on 3. My vehicle was also burning oil. I took it to the dealer(Napleton). They changed the spark plug. That didn’t fix the issue. I took it back because the check engine light came back on. Napleton Downtown Chicago, IL, kept the vehicle for 5 months because they stated they had to replace the engine. About 2 weeks ago my check engine light came back on. I made an appointment to take it into to Napleton Downtown Chicago on November 27, 2023. Yesterday November 22, 2023, my vehicle cut off, started smoking and didn’t cut back on, I had to have it towed to Napleton in Urbana, IL. Clearly this vehicle is having engine problems. I been telling Napleton Downtown Chicago that there’s a defect with this vehicle and to replace it. Please look into for me.

Oil leak from oil pan area. Took the car to the dealer twice to get it fix and the problem temporarily stop but now is continuing to leak again. All they did was retighten the oil plug the first time and then the second time replaced the oil plug with a new one. They said it was a bad oil plug washer and now it should stop the leak, but now it’s leaking again. Took notice of the leak when the car was parked in garage overnight and a pool of oil formed under the car again. This is scary because losing oil like this is not normal and if it continue it could seize the engine while the driver is driving it risking the safety of the driver and car.

After having a warranty repair for a valve cover gasket' at CENTEREACHHYUNDAI, I picked up my car. Only 8 minutes into my drive home the engine light went on and engine error code appeared. At that piont smoke was coming from the hood when I heard a pop and flames appeared at my passenger side window. I turned the car off removed my phone and exited the vehicle. No one else was in the car but within minutes the fire was totally involved. I also noted it took the fire department very long to arrive. If anyone was trapped in the car they would have peristed.

Catalytic converter is failing Lane collision warning failing driver side rear view mirror

Vehicle has developed excessive oil consumption. No leaks to be found. Using approximately one quart a week.

The contact owns a 2020 Hyundai Santa Fe. The contact stated while driving at an undisclosed speed, the check engine warning light flashed on the instrument panel, prompting her to pull into a parking area and contact Roadside Assistance. The vehicle was towed to the dealer, who diagnosed a failure with the knock sensor. The vehicle was repaired, but the failure reoccurred. The vehicle was again towed to the dealer, who diagnosed a general failure with the engine, requiring a replacement engine. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The failure mileage was 14,500.

Intermittently when you turn the left turn signal, it will be a delay of 2-3 seconds to actually turn on the lights. Usually it happens in the morning when cold.

Sitting in parked vehicle. Opened the rarely-opened panoramic sunroof. Heard unusual sound,. Looked next day and noticed a stationary glass panel forward of the sunroof had shattered all the way around but had not collapsed (yet--have tape on it to keep it intact until repairs can be made). Hyundai does not consider this to be a warranty issue. The warranty states in the "What is not covered" section: "- Action of road elements (sand, gravel, dust or road debris) which result in stone chipping of paint and glass." Dealer documented it and basically said "too bad". Since the issue being reported was NOT caused by road debris etc., This should be a warranty coverage matter. Similar instances have happened to others (entire sunroof) and has been reported. This glass should be LAMINATED--not tempered--but is not. This could be a major safety concern.

I had been driving my vehicle for about 5 minutes when I heard what sounded like a loud bang or gunshot followed by the sound debris falling. I realized the front piece of my panoramic sun roof had literally exploded. When I got out to look at it the glass around the hole was pointed upwards so it looked like it exploded from the inside out. The glass had no prior damage and nothing hit it before the explosion. I was on a paved road by myself.

Oil pan cracked leaking oil

I was driving and heard a sound like an explosion. When I was able to safely pull over, I examined my 2020 Sante Fe and noticed the panel of glass right before sunroof exploded. No rock hit it, just exploded.

I was driving on an interstate highway at approximately 75 mph. I had cruise control activated. Suddenly the car dramatically slowed down, accompanied by rapid beeping noise. Luckily, there was no one close behind me.

The vehicles oil was changed on 3/22/23 at 22,395 miles. Almost 3 months and 1500 miles later when driving the engine seized. No lights came on. Vehicle was towed to Hyundai dealership who said it is the fault of whoever did the last oil change as the drain plug came loose. After doing research it appears that this is a known issue with Hyundai. Also, fresh oil was all over the driveway which was not noticed when car was leaving the driveway.
