2021 HYUNDAI SANTA FE Unknown Or Other Problems

Replaced horns a couple times, after doing research, this seems to be a deeper and ongoing issues with this car ok a larger scale. Horns die out or stop completely, causing multiple replacements.

Horns stopped working entirely. Car was crossing into my lane and I attempted to honk horn and no sound. No warning lights or messages on dash. Is available for inspection. No inspections conducted currently.

Horns assemblies are Failing repeatedly. Since ownership of the vehicle (2023 and a CPO Platinum Wrap), I have had to replace a single horn, or both horns three times with local Hyundai dealerships. mostly the right horn would fail, then the left. I am currently making efforts to have my vehicle’s horns serviced for the fourth time as they are not working. I have been to my dealership on Dec 16, 2025 & Jan 15, 2026, to have the horns repair to no avail. In December, a diagnosis was performed with no action. Yesterday, one part (horn) was not available, and I was quoted a fee of $400 to perform the task. This is extremely concerning as this is not a consumable part or fluid. This is a required vehicle safety item. There are TSB's for other models in the Hyundai line with similar failure of horns ( TSB's: 24-BE-018H...

The horn on my 2021 Hyundai Santa Fe has completely stopped working. This is a severe safety hazard. I recently attempted to warn another driver who was drifting into my lane but was unable to, forcing me to swerve and nearly resulting in a head-on collision. The horn failed without any warning. After researching online, I have found that this appears to be a known issue with the Santa Fe model and Hyundai vehicles in general. I am requesting a diagnostic and repair as this is a safety feature failure that could lead to a serious accident. Please let me know if this issue qualifies for a recall. Thank You

The car horn stopped working very suddenly, without any prior warning, while I was driving. The car has around 36000 miles on it, so the horn dying out was a surprise. Driving without a functioning horn has also become a safety issue. I have an upcoming appointment with the dealership to diagnose and fix the problem.

I am writing to formally report an issue with my vehicle that I believe may warrant a recall investigation. The issue involves the fuel door, which is failing to open after the car has been turned off. This has occurred repeatedly and is preventing me from refueling the vehicle, posing a significant inconvenience and potential safety concern. Despite ensuring that the vehicle is unlocked and powered down as instructed, the fuel door remains stuck and will not release. This malfunction requires manual intervention or technical assistance each time I need to access the fuel tank, which is not only frustrating but could also become hazardous in certain situations. I would appreciate it if this matter could be reviewed for possible recall consideration or guidance on next steps. Please let me know if additional documentation, including my VIN or service history, is needed.

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.

Horn stopped working on my 2021 Santa Fe. Reported to dealer and they confirmed that both horns (high and low?) were broken. There was no indication that the horn was malfunctioning. It worked and then it didn't.

I bought this vehicle brand new in 2021. It failed its first safety inspection in 2022. I was asked ..did you know your horn is not working? Took it to the dealer and was told this has been a common issue, the relays are freezing and popping in the cold. Have lots in stock because of this issue. The service dept has stated on each replacement parts are in stock because this happens all the time. It has now become an annual replacement for me. I just had my third set of horns in 3 years installed on 1/21/25. So for one this is a vehicle safety requirement to pass inspections in NYS. Two: I dont know my horn isnt working until I go to use it because I need to in a dangerous situation and its dead. There is no fix other than replacing the horns which is a...

I hadn't been begging Hyundai to help remove a public safety risk for years ! Today, The service lady witnessed my car have a severe safety defect. Although initially offering a rental car, ultimately denied due to my inability to provide insurance until the 1st. My insurance is valid until tomorrow. N they REFUSED to provide the rental without the insurance being dated for 4 days from today. The man in the service office asked if I needed a ride home!? Suggesting i drive the car home. Hyundai has witnessed this cars emergency parking failing, and are aware that this car has rolled out of gear TWO TIMES, W my son in it !!?? Until today, claiming unable to "duplicate" the defect. And unable to "substantiate " my claims due to not being able to duplicate the deflect. They duplicated the defect today. The car no longer has a safety...

Rearview Camera does not work (Signal Loss message appears). I nearly hit 1 adult and 2 small children that were passing behind my vehicle in a parking lot. I felt the need to report this even though a recall is being put into place. I have an appointment already to have the camera repaired.

The fuel door release button on my SUV has stopped working. It is a press and spring opening fuel door. While trying to get gas, it would not open, prohibiting me from putting gas in my car. (May 18, 2024) I went to the dealer on a Saturday in an emergency instance and while in the lane, because the shop had no openings, the technician had to remove the inside trunk panel and other trunk parts to separate the fuel door compartment from the car to get the fuel door open. He put tape over the door engaging mechanism, so it would not engage and become stuck closed again. There is no inside car release button for my model. Also, there was no indication in the health stats in the My Hyundai mobile app. I scheduled a service appt for the following Friday and received the notice that the part...

Vehicle horn continues to stop working. Problem occurred within a month of purchase. I have had it repaired 3 times, and each time it has been repaired it works for only a few days and then stops working. I am tired of paying to have it fixed, only to work a few days. It has been a safety concern as I have not been able to alert pedestrians, other vehicles, or animals to my presence. Having a working horn is a required safety feature for my employment and driving on company property.

On two different occasions the car is rolled away from me and while I was out of the car and walking away from the vehicle. The first time it rolled backwards across the parking lot and into a flagpole and the second time it was a McDonald's parking lot and I was able to jump back in the car in time but it started to roll forward as I was bending down to get my debit card off the ground.

My sante fe has shifted out of park and rolled away from me on 2 occasions. The first time I was about 30 feet away when my son and husband started screaming for me. The car we rolling across the parking lot. I tried to jump in and hit the brake but was unsuccessful and we slammed into a flag pole. The dealer ran a code reader on it and there was no codes so they denied responsibility. Basically called me a liar [XXX] it happened again In McDonald's drive thru The window lady witnessed it. I got out to.get my debit card and as I was leaning down the car rolled out of park snd started coasting away from me. I again, contacted my Hyundai who assigned another case manager. This case manager promised to reimburse me for a rental I paid for the first time the car rolled...

In order to start again I have to switch transmission to park and turn key ignition switch to start vehicle, it start again and I can continue. While driving and must stop due to traffic light, stop sign or intersection and the auto start is on as soon as I lift the foot from the brake pedal to continue driving the vehicle stumble and it completely stop the engine while the vehicle transmission is still in drive.

April 2022 My 2020 one, Honda Santa Fe started rolling backwards in rolling to a flagpole as I was walking away from the car. I tried to to catch up with the car. It had my family inside screaming. But I was unable to stop it from slimming into the fireplace. I let Hyundaiusa know. They recommended that I take the car to the dealer. They promised to reimburse me for rental car after the diagnostic came back. they found nothing wrong with the car and never paid for the reimbursement Now September 2023. Same thing just happened again. I was in McDonald's drive through and I drop my debit card so I got out to get my debit card. I got out of the car and had to close the door and as I bend down at sensed the car start starting to pull away. The car once again...

The panoramic sunroof which is made of tempered glass is a large piece above the back passenger. There is also a small piece above the windshield. The sunroof sits in between these two pieces (not made of tempered glass). I noticed a crackling sound driving my daughter to day care on Friday August 11. I couldn’t figure out what it was. The next day I was on the highway, my husband driving our car and my toddler in the back when there was a loud pop like a gunshot. We pulled over assessed the car and realized the panoramic roof was shattering. We drove it home and realized the front piece above the windshield was also shattering and there was no impact. I googled this and apparently it’s happening to a lot of people and the dealerships aren’t helping saying it’s not a manufacture defect when in fact it is....

My transmission keeps slipping. I was on freeway this time and it slipped out of gear but it was like I pushed all the way down on pedal the RPM went way up so I had to wait until it slipped back into gear to be able to continue on down the freeway. I backed up traffic for a minute because I can't put on gas until it goes back in gear.

Front sunroof shattered on the interstate at 80 mph. There were no other vehicles near me and it was an unobstructed road (no bridges crossing the road) temperature was 40 degrees and sunny.

There were 2 instances where my vehicle stopped. Once I was driving 15mph and it said “Put car in Park”. The 2nd, I was driving 45mph and the vehicle said “Step on the Brake to start car”. I have also had 2 instances where my odometer just keeps going up and down. He 2nd instance, the car was making a ticking noise and hazard along with other lights were flashing.

After jacking up the car to do a tire swap from winter tires and wheels to the OEM tires and wheels on the front passenger side using the factory supplied scissors jack the vehicle rocked slightly, causing the jack to fall over and the vehicle to drop. I had already completed the tire and wheel swap on the driver side of the vehicle without incident. At this point the lug nuts were loose but had not yet been removed, so no damage to the vehicle occurred. This event happened in my garage that has a flat concrete floor with an epoxy coating. I was not touching the vehicle at the time. The vehicle was in park but the electronic parking brake was not manually set (not sure if that can be done). I believe the transmission (8 speed DCT) allows too much movement fore and aft before engaging the parking...

Unknown vigorous shaking in rear of vehicle check engine light on. Stopped after turning car off and restarting. Hyundai found no causes and no codes when inspected for issue.

THE MANUFACTURER HAS NOT ISSUED A REMEDY FOR THIS RECALL #22V746000 SINCE THE INITIAL FILING OF THE RECALL ON 10/6022.

I have been aware of this SAFETY DEFECT/RECALL for over 2 months now yet Hyundai has no remedy planned thus placing owners and others on the road in serious danger. This is unacceptable and I wish to file a formal complaint with the NHTSA. (NHTSA recall number 22V-746)

The vehicle will not move forward or reverse, when drive or reverse is selected. The car has been at the dealership since 10/11/2022. I was informed that the transmission needed to be replaced. No one in the hyundai organization (including the dealership) can tell me when replacement will be.

While on a high speed highway in New Jersey the transmission suddenly lost power and the car was unable to move. It had to finally be towed to the Hyundai dealer on 7/26/2022 where it remains awaiting a new transmission. Neither dealer or Hyundai Corporate has any information as to when new transmission will arrive and be installed.

The passenger door has a sharp edge at the bottom exactly like the palasade hyundai recall. Both my daughter and my 82 year old mother have gashed their ankle on the door. In the case of my mother she was lucky we did not need stitches! I have a picture of the injury. I made a case submission to Hyundai.

I keep my vehicle backed into my single car garage. I have had 3 incidents in the last couple of months Beginning of mayish to now, where I start the vehicle, put it in drive and it does not drive. Twice it started to reverse and today it acted as though it were in neutral. I've taken video of the last 2 incidents showing that drive is selected, the dashboard and the Birdseye camera. My dealership is working to resolve but has stated to plan on my vehicle being there for awhile. This seems to be quite dangerous. When I turn the vehicle off and restart it, drive works.

Problem #1 - At least 4 quarts of oil spewed from the oil tank and covered most of the engine for an unknown period time. There were no notifications, alerts, or any other indication concerning the oil tank having 1 or less quart of oil. Ultimately, there are at least three (3) questions that need to be addressed 1.In a 2021 Santa Fe, what would cause both the timing and valve covers to leak out at least four (4) quarts of oil out of the oil tank onto the engine. 2.Why was there no notification, alerts, or indication that the oil tank only had less than one (1) quart of oil. 3.What other damage could there have been to the engine beyond the several parts identified as needing to be replaced, that was not identified. A Chronological Order of Events is available.

While driving the car in cruse control the speedometer would jump up and down rapidly making the car accelerate and break. The warning lights come on saying the forward, side back sensors are off. At times stepping on the breaks a plastic bottle crunch sound will occur but the breaks were fine. I scheduled a repair but was still driving the car. Then I approached an intersection and the light was turning green to yellow so I stepped on the breaks only to have the pedal go to the floor without resistance and no breaks at all. I had to drive through a red light endangering myself and others at that intersection. I pulled into a parking lot and the breaks were working again. Car has been towed to the West Herr Hyundai Dealer on Transit Rd Williamsville, NY for repairs.

Vehicle stalled 5 times when finally got it to restart wouldn’t accelerate more than two mph. Broke down on a busy road was finally able to get the car into a parking lot but was almost hit from behind cause the vehicle was obstructing traffic. Towed to dealership where was told it would take them a week to look at it and they won’t provide any alternative transportation for me that I would have to pay out of pocket. My car is only 2 months and 2400 miles old

Engine shut off while driving 70mph in the middle of the mountains in PA during a road trip from VA to MI, 2 adults and one child. No Warning No Check Engine lights No alarms, just shut off. I tried to press the ignition start button but it would not function until the engine was in park, gave no warning or alarm when I pressed it, the engine start button wouldn't respond. At Shutoff, going ~70mph, I had: Zero acceleration Zero power No blinkers No Instrument Cluster (LED Cluster screen installed) The only way I could signal to merge onto the shoulder was to turn on the hazard lights and attempt to merge from the fast lane to the shoulder, completely crossing faster traffic with no blinkers to guide my merging and warn other drivers on the highway. Instrument cluster turned white as if it was being reset and music...

DARK SPOT IN LOW BEAM HEADLIGHT FIELD CAUSES LOSS OF VIEW FOR DRIVER AS THE DARK SPOT PASSES FROM OBJECT TO OBJECT. PEOPLE OR ANIMALS, EVEN SIGNS LOSE ILLUMINATION AS THE DARK SPOT COVERS THEM. REFLECTIVE BARRELS IN CONSTRUCTION AREAS LOSE THEIR REFLECTIVITY AT NIGHT AS THIS SPOT COVERS THEM. THIS OCCURS ON THE LOW BEAM FUNCTION. HYUNDAI DEALER SAID IT IS FACTORY CREATED TO PREVENT NIGHT BLINDING OF ONCOMING VEHICLES. TO ME IT IS A SERIOUS PROBLEM FOR THE DRIVER OF THE HYUNDAI. WHEN DRIVING IN A CURVE THE DARK SPOT MOVES WITH THE SHAPE OF THE ROAD SO THE DRIVER LOSES THE ABILITY TO SEE EVERYTHING IN THE LIGHT FIELD.

WHILE IN DRIVE AND STATIONARY, MY VEHICLE HAS CONTINUOUSLY CAD CONNECTIONS ISSUES WITH MY MOBILE PHONE. I HAVE RECEIVED THE SAME ERROR MESSAGE STATING 'PHONE NOT RESPONDING. PLEASE RECONNECT IT AND TRY AGAIN.' THIS HAS HAPPENED WHILE DRIVING THROUGH AREAS I'M UNFAMILIAR WITH AND PUT MYSELF AND OTHERS AT RISK WHILE TRYING TO REGAIN CONNECTION. I'VE LEFT MY VEHICLE AT THE DEALERSHIP, BUT WAS TOLD THE PROBLEM WAS MY CELLPHONE AND WAS ADVISED TO PURCHASE A NEW PHONE. WHEN I SPOKE TO THE WOMAN AT THE CORPORATE HYUNDAI NUMBER, SHE ADVISED ME THAT MY PHONE WAS VERY MUCH COMPATIBLE AND SHOULD NOT HAVE ANY CONNECTION PROBLEMS, WE TROUBLESHOOTED MANY TIME, BUT I STILL CONTINUE TO HAVE THIS ISSUE.
