2023 Hyundai Santa Fe owner complaints

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

Horn Failed. Would not sound, making it impossible to warn people if car might hit them or their vehicles or about any other issue they would need timely reporting about. Car was brought into dealer and 2 horns assemblies were replaced as non-functional

Both horns have failed for the second time since the vehicle was purchased new in November 2023 and is currently showing 25,000 miles. The first set was replaced under warranty at a Hyundai dealership approximately 1 year ago. Not having a functioning vehicle horn is a safety hazard that would fail annual vehicle safety inspection testing in my state.

My back up camera is not working properly. The picture at times is scrambled and starts floating around on the screen. This was not the first time this has happened. I reported it to the dealership service department when I first noticed, about a year ago or longer. They updated the software and told me that would correct the problem. Clearly it did not correct the problem, if it is continuing to have 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.

Just purchased the vehicle one week ago. I bought it used from a Hyundai dealer. Just discovered that the horns don't work, either the high tone or the low tone. I discovered it when I went to use the horn to alert a driver who was coming into my lane, pushed the horn on the steering wheel and nothing! I've checked the fuse and it is fine. Internet research shows this to be a prolific problem with Hyundai's. Because the horns don't work, neither does the alarm system. I tested by pushing the panic button on the key fob. The lights flash, like the alarm is trying to fully work, except the horns don't sound. I will be bringing it to the dealer as it is still under warranty.

Emergency brakes engage while driving for no apparent reason. This has happened on several occasions over the last 6 months.

While travelling at highway speed, attempted to accelerate to pass slow traffic. Rather than accelerating, the car hunted for a gear, and wouldn't shift properly. The car downshifted but engine would not go beyond 4000 RPM and speed remained the same. This has happened multiple times. By unexpectedly not accelerating, this created a risky situation by not allowing car to pass slower traffic as expected creating a potentially dangerous situation. (Video of one of the instances exists). No warning lamps, messages or symptoms occurred up to that point. Car was brought to dealer but since no codes were contained in the computer, they said there was no trouble found.

Automobile approached and stopped at stop sign. When accelerator pressed to continue, car remained in place, shuddering (as if transmission were slipping),and making significant noise. Car would not shift out of gear, nor move. Operator shut off car and then restarted car. Car started normally and was in park without shuddering. Expectations at busy intersection was that it was my turn to move and did not do so, creating doubt on what my car might do next. Traffic flow was briefly confused and some drivers honked and were unsure what they should do. This could have caused an accident with an impatient driver re-ending my car, or with others going through the intersection "out of turn" and unclear on my situation. No lights or other warnings were displayed before this incident. It

This same scenario has happened 3 times since I purchased this vehicle - first event at mileage of 6273, 2nd event @ 7586 miles, and 3rd event @ 12,506 miles. All events were the same - while driving, dash board light start to flash and the vehicle looses all ability to accelerate. For each event, we have been able to coast out of traffic, turn the car off & restart. Once the car is restarted the acceleration works again, but the check engine light remains on along with an error code of P065312 Possible Power Train Issue. We have been very fortunate each time that we were on a road where we were able to coast out of traffic, but if this happened on a busy Interstate or Hwy traveling at high speeds we could have been rear-ended. The vehicle has been to the dealership twice for servic

The vehicle cannot pick up speed, and it is displaying the DTC- P1C2D03. This is similar to the issues that led to "Safety Recall 236 to repair a condition involving the 8-Speed Dual-Clutch Transmission (DCT) system" in earlier model years (till 2022) for certain Hyundai and Kia vehicles. NHTSA should issue a recall for 2023 model years also as Hyundai has not addressed this issue to the fullest extent in 2023 model years.

Shuddering Issue with Current Vehicle: - Problem: Progressive shuddering during take-off, accelerating, slowing down, and braking uphill.

First- it has been reported to dealer at least twice when car was in for other service. They said they could not reproduce. When speeding back up from a stop on near stop, especially in a right turn, the engine will not accelerate. After a second or two it finally takes off. During this time, I fear getting hit by another vehicle, either from behind or to the side. It is very scary and puts me and my passengers at great risk! There was no warning indication at all. The date mentioned was the most recent time, but the issue has been happening since the car was brand new. Again, NO help from the dealer.

Both horns on my 2023 Hyundai Santa FE have failed 3 times. The first set was covered under warranty (3/24), the second set cost $499.64 (3/25). Now both horns are nonfunctional after just being replaced this Spring. After reviewing many complaints on the Hyundai community form, it is very obvious there is a major issue with their horns ( and not just the Santa Fe model). Twice this week I was in need of my horn to alert other drivers but instead had to make quick maneuvers to avoid an incident. My vehicle currently cannot pass a state inspection.

On a clear road a sencor comes on detect comes on says detection collision. The breaks come on when you are traveling on interstate or two lane roads. When you are traveling 75 mph and breaks come on all of a sudden on the highway. We are lucky we never got hit in the back of the car going that fast. We will stop 75 to 35 mph in 10 seconds.

This hard brake peddle pressure issue started out immediately on an occasional basis but now occurs almost every morning on first start of the day. Press on the brake pedal - it's very hard to deflect - and if you don't overpower it to deflect the pedal enough to activate the brake lights, it won't start. Once you get it started the first time, brake operation will be normal for the rest of the day. A specialty maintenance blog has covered this issue comprehensively. The Hyundai Maintenance website is apparently aware of this potential problem. According to [XXX] , it is likely caused by a malfunctioning brake booster or vacuum leak and recommends taking the vehicle to your dealer for diagnosis and repairs. This is apparently a common problem across multiple Hyundai models since there are

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.

I purchased this SUV new and noticed an issue with the automatic intermittent wipers. The dealership has replaced the windshield sensor and issue is now unreliable at best. Service department told me to simply wipe the sensor off or pour water onto the sensor to get the wipers to work. That seems to work for about 3 wipes and then stops again. Also, the driver seat changes position by itself while driving, and the advanced cruise control failed to provide any braking and almost caused me to rear end a stopped car in freeway traffic. Additionally the advanced braking system does not work at all... I had the salesman check the settings and they are turned on, but do not provide any braking function. The alert system does provide a warning if a car turns a corner in front of me, but f

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

I purchased my 2023 Santa Fe brand new off the show room floor in Jan 2024. After about 6k miles when braking on the highway the entire vehicle would shudder and shake including the steering wheel. I took it into the dealership where I was informed this is a KNOWN ISSUE with this year/make/model with the rotors. They claimed they would turn the rotors but if the issue persists they would replace them. About 2k miles later (apx 2 months) the shuddering happened AGAIN. So I made an apt to get them replaced where the new service tech tried to tell me again this is a KNOWN ISSUE but now I would be responsible for a $250 replacement of the rotors. I refused to pay as they are within the 12k or 1 year warranty and they refused to replace them. That service tech also said the day prior he had to
