2023 Hyundai Santa Fe Complaint Log

While driving the engine dropped to 10 mph and would not respond to the pedal inputs. It is available for inspection. Dropping to 10 mph in traffic on a roadway doing 70 mph or even 35 puts everyone on the roadway in danger. The problem was not reproduced but was comfirmed by the dealer who inspected and serviced it. There was no warning before it happened but the dash displayed many warnings and even sent out an email when the engine failed. This was the THIRD of five times that it has happened so far.

The forward collision warning system engages and slows the car, often very abruptly, when on the highway and only when cruise control is on. It happens after we have been on the highway for a few hours, thus the dealer cannot reproduce the incident. It happens a few times on every road trip and is very disturbing when there are no other vehicles or obstacles in the road or nearby. We have reported this to the dealer several times and they can find nothing wrong. I provided a photo to the dealer of the dashboard showing the cruise control on, the forward collision system DISENGAGED, and the forward collision warning activated. Dealer states they have recalibrated the system but can replace no parts unless a part is found to be faulty. The latest suggestion yesterday from the dealer was to "get out" of the car before the issue gets worse.

A few times recently our car has had a hard time starting even though it's only a year old. It's like it's having a hard time turning over. And then when driving, it has a hard time accelerating - it almost feels like the car is in neutral while trying to drive. It jerks and shimmies to the point where you have to pull over to see what's going on. We were on a pretty busy road and couldn't accelerate to the point of safely merging into traffic. An online forum said it was a "loose ground" that's causing the acceleration issues.

Horn does not function. Trip to the service department and was advised it’s a known issue and they will call me when one comes in. This car is one year old and the horn not working is a major safety concern for me. A search online shows this is an issue for several buyers without a recall notice.

I was driving down the expressway and my sunroof exploded. It scared me so bad that I swerved and almost lost control of the car. I thought something hit me.

While driving the engine dropped to 10 mph and would not respond to the pedal inputs. It is available for inspection. Dropping to 10 mph in traffic on a roadway doing 70 mph or even 35 puts everyone on the roadway in danger. The problem was not reproduced but was comfirmed by the dealer who inspected and serviced it. There was no warning before it happened but the dash displayed many warnings and even sent out an email when the engine failed. This was the SECOND of five times that it has happened.

There is an extreme amount of hesitation/delay from when you depress the accelerator and when the vehicle accelerates. I have had multiple incidences (both from a complete stop and while already moving) where I depress the accelerator and there is a concerning amount of lag time before the vehicle initiates movement. This has almost led to multiple accidents. This defect happens in all drive modes. This issue appears to have gotten worse over the time we have owned the vehicle. We did not notice this issue earlier on. We bought the vehicle brand new in Dec. 23.

I purchased a 2023 SantaFe brand new mid-January, In June I noticed an issue with the car. I called Steele Hyundai in June to get an appointment and was told by Margarita that they didn’t have availability until September. REALLY. So, I went online and filled out an appointment and got an earlier appointment for August. Crazy Right? I then contacted Hyundai corporate to file a complaint, and was given a case number and Tina is the case worker. I brought the car in on [XXX] and left it there till [XXX]. Problem ended up a transmission needed replacement. WOW, quality!! I picked the car up on that Friday and it sat in the garage during labor day weekend. I first got back in the vehicle on Tuesday, [XXX] and knew immediately it wasn’t fixed. I decided to go to a different dealership for service World Car Hyundai in San Antonio and made an appointment for [XXX]. I called [XXX], spoke with Todd and explained needing a loaner. He asked me what I was bringing it in for, told him I had the transmission replaced. He said to give it a week to get the computer to adjust to my driving. SAY WHAT? So, I did and no bueno. I called again on Thursday, [XXX] to bring it in to World Car and spoke with Justin and made an appointment for Tuesday [XXX]. On Saturday, [XXX], we took the car to Austin for my husband to determine what he thought, he said, “this car isn’t drivable”. On Monday, [XXX], I cancelled my appointment for World Car because Todd said Steele knows the history of what work they did, and it would be best. My husband dropped the car off at Steele on Monday without an appointment. The service director Rene is familiar with my vehicle and today when I called him about the car, he said it’s the TRANSMISSION AGAIN. My question is what is wrong with the quality of the engineering or the quality of the service technology. I DON’T trust this car, I need a SOLUTION. I need an answer. I need you to fix this problem with this C INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Several times lately of extended crank. Saturday evening, car had been parked for 4 hours, did remote start and had extended crank of about 2 seconds. Car ran for about 3 minutes before we left. We left home and hit main road, tried to accelerate and vehicle seemed to go into limp mode. Would keep cutting the fuel out if tried to accelerate even above 40 mph. No check engine light came on. Put in neutral, could not get above about 3500 rpm. Vehicle was in smart mode where decides which mode to be in (normal, fuel economy or sport), when would try to accelerate it would try to change to sport as it knew power was not there. Was on a 6 lane highway and could not get up to speed. Finally was able to pull to side of road, shut engine off, waited a few seconds, restarted and issue went away, still no check engine light. I have contacted my local dealer, they said they have seen on another vehicle, was not sure of outcome, having service manager call me. Lots of complaints online forums of similar issues.

The horn has broken 4 times. I was told that it is a design defect in the car and there is no permanent fix. Water gets in to the horn when it rains and because of the location of the horn it would have to be moved to fix it. Hyundai is aware of this safety issue and has not issued a recall because there is no permanent fix. They are supposed to be buying back my car but are dragging their feet. I'm sure this is an issue in more than just my car and it's very unsafe for the horn to just stop working.

Tire inside sidewall blew out on rear right tire. No curb, no pothole. 40mph speed

The contact owns a 2023 Hyundai Santa Fe. The contact stated that the horn was inoperable. The lower horn sound had dissipated. Then shortly after the higher horn stopped working. There was no sound when the horn pad was depressed. There were no warning lights illuminated. The vehicle was taken to the local dealer who informed the contact about the cost for the repair, but the vehicle was not diagnosed or repaired. The manufacturer was contacted, opened a case, but no additional assistance was provided. The failure mileage was approximately 72,000.

AC evaporator drain design problem June, 2024 approx. 3500 miles under warranty, AC evaporator drain line backed up into the passenger front right. Brought it to service - they unclogged and drained the line at no charge. June 2025 approx. 12,K miles under warranty, AC drain backed up again. The excess water drained onto my feet as a passenger and collected under the front seat, saturating the rug area, potentially causing additional mildew and respiratory causing irritation. Service required an appointment. drained it charged $88. Filed a complaint incl Hyundai Motors ; was told the $88 charge was irreversible - cause was weather. The CAR HEALTH HAZARD seems to stem from a major design flaw The air intake is in the windshield wiper cowl resulting in wet tree and leaf debris , bird droppings, etc collect even when the car is not in use. Thus, when heat or air conditioning is activated, air comes in through the air intake and then through the difficult to acces filter recessed behind the glove box , then into the passenger area When the AC drain hose is plugged, it backs up through the dirty filter and then out, to accumulate under the passenger seat allowing more mildew. Re:My 2024 mile blockage, the water was drained, but the filter was not mentioned. In 2025 with the $88 bill, the water was drained no mention the filter. Draining the water does not correct the problem. It should be required at every service the l drain hose is checked, water drained. and filter changed at no charge until a design correction to cover the cowling or an interim solution is installed We lnotice that we have sporadic respiratory problems in the first of miles of riding in all the car From Hyundai Motor America - We expect reimbursement for the $88 service charge. Warranty draining the water and new filter annually. and an NHTSB approved fix of the problem and an NHTSB approved redesign of future models

I was driving at around 11 a.m. on a city road at about 30 miles per hour when front passenger tire suddenly popped and car began to swerve almost colliding with vehicle in adjacent lane. The TPMS alert showed up on dashboard after the tire popped. There were no potholes or any objects that the car hit. The car along with tires had been inspected during routine maintenance at the dealer five days prior to this incident and no issues were found on tires or any lights on the dashboard. There were also no symptoms leading up to the tire suddenly popping. I contacted the manufacturer who referred me to an authorized center. After submitting the claim at the authorized center, they provided a replacement 255/45R20 at 50 percent discount.

Driving down the interstate yesterday & heard a very loud ‘POP!’ Looked when I got home to find that the sunroof glass had shattered (as has, apparently, happened to more than a few vehicles by Hyundai, as well as other manufacturers), & fell onto the fabric liner below it. Thankfully, I did not have any of my grandchildren in the back seat at the time, & the sunroof was closed. At the very least, Hyundai needs to replace and repair the glass, & be sure, before it’s returned to me, that it’s better than it was when it was new.

WHEN I WAS DRIVING TO WORK THE MORNING OF 5/20/2024, MY PANORAMIC SUNROOF EXPLODED OUT OF NOWHERE. PART OF THE GLASS FELL ON MY HEAD RESULTING IN A CONCUSSION.

Driving up steep hill to my mom’s house car would not drive up, as it hesitated I pressed gas pedal to no avail. I turned off car, got out & nothing was blocking me. Turned car back on & accelerated, this time it went forward.

The contact owns a 2023 Hyundai Santa Fe. The contact stated that the vehicle was overheating while driving. Additionally, the contact stated that upon noticing that coolant was leaking onto the ground, he opened the hood and discovered that coolant was leaking from the radiator. There was no warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed that a foreign object had struck the radiator, causing coolant to leak into the engine compartment. The dealer informed the contact that a failure caused by a foreign object was not covered under warranty. The vehicle was not repaired. The contact stated that upon examining pictures of the failure provided by the dealer, he noticed that there were rocks stuck in and near the radiator. The contact determined that the large gaps of the front grill were allowing foreign objects to strike the radiator. The manufacturer was notified of the failure and a case was opened; however, the case was later closed. The failure mileage was approximately 11,591.

I've been driving in Arizona on southbound [XXX] just south of [XXX] and noticed an issue that is very odd. I have a 2023 Hyundai Santa Fe that has Highway Driving Assist that does both speed control and distance from the vehicle ahead of me and Lane Keeping Assist. After I pass [XXX], but before an overpass for [XXX], my vehicle, if those systems are on, goes haywire and all those safety systems turn off. I have experienced it on at least 3 of the lanes on that stretch. It happens both early in the am and later regardless of sun. It doesn't happen on northbound. As more cars have these features, this interference should be looked in to. I have not experienced this on any other of our highways. Here's a link to the the rough location.

From a complete stop when pressing the accelerator, the vehicle does nothing. This can last 1 second or in longer episodes it can last 4-5 seconds. No lights on the dash. It’s random and happens sporadically. But when it’s bad, you have enough lag to count to 5 and turn on the hazards

Unknown issue, but the car has auto braked 2x on the interstate going 65mph. No cars were around me nor any objects in the road. It stated auto braking and sensors going off. Resolved itself within 60 seconds, but did almost cause me to be rear ended because a tractor trailer was quickly approaching me.

The contact owns a 2023 Hyundai Santa Fe. The contact stated that while driving at various speeds, the Emergency Braking System was erroneously activated, causing the vehicle to abruptly stop in the middle of the road. During the failure, the message "Emergency Braking System Engaged" was displayed. The vehicle was taken to the local dealer who was unable to determine the cause of the failure. The manufacturer was not contacted regarding the failure. The failure mileage was unknown.

The harness does not stay tight on the child’s chest. The harness was adjusted to the correct fit, when pulled to check the tightness the harness does not stay taught. It releases without pushing the release button

Sunroof exploded at highway speed glass was contained by interior fabric. Sounded like tire or gun shot . Was able to stop but frightened. Took to dealer and left it. Car has less than 3500 miles on it.

While driving on [XXX] at 65 MPH, without warning the sunroof spontaneously exploded and shattered. It produced an extremely loud bang, like a gunshot, startling me to where I almost lost control of the vehicle. There were no vehicles in front of us, no vehicles behind us, and nothing above us (not traveling under a bridge or overpass). We were traveling in the state of Mississippi at the time and it was 58 degrees and raining, NO HAIL was coming down ever. The dealer cannot explain why this would happen but would not cover it under warranty. The vehicle is brand new with 4,100 miles on it when this occurred. Insurance company is paying for the repair which is now complete. The shattered sunroof is thrown away but I have pictures of it right after it happened.

The contact owns a 2023 Hyundai Santa Fe. The contact stated while driving 70 MPH, the panoramic sunroof exploded. The panoramic sunroof glass and the shades were closed. No warning light was illuminated. The vehicle was taken to the dealer. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 9,100.

The contact owns a 2023 Hyundai Santa Fe. The contact stated while driving on three occasions, at approximately 60 MPH, the cruise control was engaged, and the contact attempted to accelerate using the toggle and the vehicle accelerated to over 110 MPH. The brake pedal was depressed, and the cruise control was deactivated. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 140.

Whilst driving the vehicle a number of warning lights appeared on the dashboard. This occurred after the vehicle was brought to a stop at a stop sign. There were no outside influences before or after the warnings began. The vehicle remained operable and was driving back to our residence approximately 1 mile away. I made an appointment with the local dealership to investigate the issue. The appointment was made for the following day. Whilst driving the vehicle to vehicle to the dealership on the following day the brakes became temporarily inoperable forcing me to leave the road and hit the right hand kerb. After pumping the brake pedal several times the brakes re-engaged and I was able to stop the vehicle. The dealership have explained that a rear wheel speed sensor (ABS) had failed and was sending messages to the the braking system which made the braking system inoperable. The dealership replaced the sensor and at this time the vehicle is operating as expected.

On [XXX] I was on [XXX] in Houston, TX southbound in the Woodlands area when my vehicle warning light for overheating went on. I pulled over on [XXX] and contacted Vehicle Assistance and the vehicle was towed to my dealer, Northwest Houston Hyundai. There was damage to a tube in front of the radiator and a/c condenser. The damage to the tube was approximately 1/16 of an inch in diameter and supposedly was caused by debris entering through the front grille which is designed like a large egg carton. The dealer spokesperson informed me that they had seen many vehicles like mine (2023 Santa Fe) with the same type of damage. I have been trying to settle this with Hyundai but they feel it is normal road damage and that the wide open grille design that allows it is not their problem. I can't even get them to approve a third party screen to protect the engine radiator from further design. They will not answer the question as to whether or not installing this item will void the warranty or not. It's dangerous to break down on a manor highway in a manor city particularly for us senior citizens. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While merging into the highway at approximately 49 to 52 mph, acceleration was applied to merge into the highway between moving vehicles. The vehicle responded by greatly increasing the rpm but not applying the power to the wheels. The engine revved up with very little acceleration. After 5 to 8 seconds, the power was finally transferred to the wheels and the vehicle sped up. The vehicle behind me had to apply the brakes since I basically cut them off. This was the second incident of this type.

The contact owns a 2023 Hyundai Santa Fe. The contact stated that while operating the vehicle, the horn was inoperable and inaudible when pressed. The cause of the failure was not yet determined. The local dealer and manufacturer were not notified of the failure. The failure mileage was approximately 31,000.

Vehicle does not detect motorcycles in the blind spot. I did not look over my shoulder and began moving left with a turn signal when I glimpsed a motorcycle next to my vehicle. The motorcycle quickly swerved to the left and I returned to the right lane.

See attached document for complaint

Sunroof exploded while traveling at highway speeds causing glass to fall into the cabin. No impact from rocks, just exploded out of nowhere. Massive loud explosions sound

While parking, the brakes failed. Although the brake pedal was correctly and completely depressed the car failed to stop until it hit the building causing damage to structure and injuries occurred to passengers. The brake pedal pulsated but the car did not stop. Prior to this, the brakes would sporadically pulsate while braking. There were vehicle health issues that were reported.

While parking my 2023 Hyundai Sante Fe, I hard pressed the break and pushed the Park button. The engine revved up and the vehicle took off instead of going into park; smashing into a building. The parking block was 6ft from the building. The engine accelerated to a high enough speed that it totaled the vehicle completely out. The engine code readings after the vehicle was towed to a repair shop was P0112 and P0114. The mechanic says that's the initial cause of the accident. The insurance reps are supposed to be following up on the mechanics diagnostics currently. There were no warning lights or anything on before the issue occurred as this was a brand new vehicle with only 8,000 miles on it.

Throttle randomly cuts off or hesitates. It has done it about 15 times Dealer says no problem found. There is a lot of reports on the internet of the same problem.

Windshield started to crack after 150 miles on the car from driver side spreading across whole line of sight. No visible or audible rock hit the windshield

While driving the engine dropped to 10 mph and would not respond to the pedal inputs. It is available for inspection. Dropping to 10 mph in traffic on a roadway doing 70 mph or even 35 puts everyone on the roadway in danger. The problem was not reproduced but was comfirmed by the dealer who inspected and serviced it. There was no warning before it happened but the dash displayed many warnings and even sent out an email when the engine failed. This was the first of five times that it has happened.

About three weeks after we bought the SUV, a small rock hit the windshield while we were driving on the freeway, causing a quarter-sized crack. We had it repaired. A week later, two more tiny chips appeared on the windshield. We didn't even notice anything hitting the windshield, and we only drove it on city roads with normal road conditions. The windshield seems to have very soft glass and gets cracked or chipped very easily in regular driving conditions. We've never encountered windshields this weak in our 20 years of driving experience. We feel it poses a potential visibility hazard for the drivers.

The contact owns a 2023 Hyundai Santa Fe. The contact stated that while driving at night with the low beam headlights illuminated, there was a dark shadow present in the top section of the illuminated light field causing a visibility hazard to the driver. The vehicle was taken to the local dealer who confirmed the issue was present but informed the contact that the headlights were operating as intended. The manufacturer was made aware of the issue. The failure mileage was 10.

Incident: I have been almost rear ended numerous, numerous times despite having my turn signal on an appropriate distance from my turning point. Safety Issue: The rear signal lights are small and are only located on the bumper. The location of these signal lights are way too low for most driver's to even notice them! The signal lights also look like reflectors on the rear bumper especially in broad day light, making the detection of a signal even more difficult! I do like the Santa Fe, it is my second one, but had I known that the turn signal lights were located where they are, I would have NEVER purchased this vehicle as the risk of getting rear ended is too high.

I have taken my vehicle back into the dealership because my car will sometimes unlock itself, I am constantly having to check the doors to make sure they are still locked and most of the time it has unlocked itself. Most of the time I hear it unlocking as I am walking away. It is very disturbing. It also beeps as if another vehicle is going to crash into me and most of the time there aren't any vehicles anywhere near me. The phone charger does not work, i have been having issues with this from the beginning. The steering wheel also says I have to put my hands on the wheel when I have them on the wheel. I have a video of the car going a lot of rpms and it barely moved, a golf cart passed me up. The car also locks up sometimes when I am backing up. I drive my parents to San Antonio for their Dr. appointments and am a little fearful of staying stranded either direction. My father is very ill and I am their driver. The dealer insists my car is the only one having these issues but I have read on reddit and other platforms of other Santa Fe's with similar issues. These issues do not occur ALL THE TIME, but this does occur at the most inconvenience time.

The contact owns a 2023 Hyundai Santa Fe. The contact stated while driving approximately 35 MPH and attempting to accelerate, the vehicle failed to respond or accelerate as intended. The vehicle started to decelerate and lost motive power. The contact steered the vehicle to the shoulder and parked the vehicle. After restarting the vehicle, the failure was self-corrected, and the vehicle operated normally. The contact stated that the failure reoccurred several months later. The vehicle was taken to the local dealer who was unable to duplicate the failure. The vehicle was not repaired. The failure mileage was 9,500.

The contact owns a 2023 Hyundai Santa Fe. The contact stated while driving 50-65 MPH, the vehicle stalled and decelerated to a complete stop with several unknown warning lights flashing on the instrument panel. The vehicle was restarted and operated normally. The contact drove the vehicle to the dealer where several fault codes were reset. The contact continued to experience the failure and returned to the dealer where the dealer replaced the throttle assembly and later replaced a front camera with a hard code. However, the contact stated the failure persisted. The vehicle was with the dealer but was not repaired. The manufacturer was also notified of the failure and provided the contact with a case number and a case manager to assist with the failure. The approximate failure mileage was 1,700.

My 2023 Hyundai Santa Fe Calligraphy with 14k miles showed a check-engine light. I had noticed some strange behavior in the shifting with a loss of power while driving at low gears. I made an appointment for the dealership the next morning. Was told today that the car needs a new transmission.

Vehicle has just over 4k Miles on it. Several times I tried to accelerate and while the engine RPMs would increase, the vehicle would not accelerate. Very dangerous when turning right on a red light and when merging into traffic. I came close to getting T-Boned on 4 occasions, and rear-ended on 3 occasions. This vehicle is not reliable and puts passenger lives in danger. Today the "Shifter System Malfunction-Service Immediately" warning came on and I was not able to shift into any gear and the vehicle put itself into neutral. Looking at the forums, this has been a problem throughout the Hyundia vehicle lineup for years with the DCT transmission. I don't understand how they can continue to sell these vehicles when there is a known safety issue with the DCT transmission. I have tried to contact Johnson Hyundia in Cary NC and left multiple messages with the service dept, but they have never returned my calls.

My 2023 Hyundai Santa Fe have a recall to fix the trailer hitch, since that I notice some issues with the shifting with a loss of power while driving, my car is 15k miles and showed a check-engine light. I made an appointment for the dealership the next morning. After two days, I was told that the car needs a new transmission. After 3 days still waiting for the car to be fix.

Occasionally the cruise control when accelerating will exceed the set speed and continue to climb and I will be going 20 miles faster than the set speed and climbing. The only way to sop this is to turn cruise off, slow down and restart. My thought is it happens after I have disengaged the cruise and then when safe reengage which is done by pressing the switch straight down. In my previous vehicles I would push the control up. I may be doing this by accident and giving the system an unknown command. Whatever I am doing to create tis situation is too easy to do and creates a safety issue. this has happened multiple times.
