While driving after dark, a different car traveling in opposite direction almost caused head on collision while driving in the wrong lane. Driver of the Santa Fe attempted to activate horn on vehicle to alert other vehicle that they were traveling in the wrong lane/direction, but horn failed to sound. Driver was narrowly able to avoid physical collision as a result. Driver took vehicle to dealership and it was determined both high and low horns had failed again (total horn system failure), and the dealership replaced under warranty. This is the second time in less than 2 years of ownership the horns have failed and needed to be replaced. Dealership stated horn failure is common in the 2023 Santa Fe, but is only covered under the 5 year/60000 mile warranty despite being a known defective part. Hyundai should offer a voluntary recall to repair affected vehicles with redesigned parts as...

Horn stopped working at 47,474 miles Check Tire Pressure System light is on, poor sensor at 45,650

Horn completely out, yes available. I was unable to warn another driver from entering my lane several times. Warn a pedestrian from stepping out into traffic. Confirmed by the dealer. The horn was Inspected replaced at my own cost on March 2025 by December 2025 the part is no longer operational. I asked the dealer to honor the warranty they declined saying the mileage was passed the warranty terms.

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.

At stop sign and car with auto start stop on and at the time of releasing the brake, car was not able to start engine. Car had to be shifted to parking position to start engine.

Horn has failed 4 times

Component/System: Automatic Emergency Braking / Forward Collision-Avoidance (AEB/FCA) system and/or Electronic Parking Brake (EPB). The vehicle is available for inspection upon request. What happened: While driving my 2023 Hyundai Santa Fe (VIN: XXX) at highway speeds, the vehicle suddenly and aggressively applied the emergency braking system on two separate occasions within the same day (approximately 45–60 minutes apart).

Horn No longer works in vehicle - A major safety issue

On [XXX] in Rehoboth, DE, my 2023 Hyundai Santa Fe experienced a sudden and complete power failure while reversing out of a parking spot. All electrical systems shut down—including propulsion, dashboard lights, and emergency brake—causing the vehicle to roll backward into oncoming traffic. No warning lights appeared beforehand. After about an hour, power returned on its own. A passing police officer witnessed the situation and a report was filed with the Rehoboth Beach Police Department. On September 6th, Hyundai service performed a diagnostic scan of the engine and transmission systems. No fault codes were found, and the issue could not be replicated. After sitting overnight, the vehicle restarted normally and passed a road test. The dealership documented the incident but returned the vehicle without repair, stating: “Cannot duplicate concern at this time.” I was advised to tow the vehicle in if the issue recurs and, if rolling occurs again, to...

horn has stopped working. Seems to be a systemic issue when looking online in Forums etc... I have scheduled the problem to be fixed and it is not a fuse issue. It will be a month before the dealership is able to get me in to assess the problem. This is a safety related issue and this needs to be addressed with the manufacturer.

horn has stopped working twice. Had it replaced under warranty in January of 2024. Same incident happened where horn of vehicle does not work. Seems to be a systemic issue. This is a safety related issue and this needs to be addressed with the manufacturer.

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.

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.

I was driving the car moving in reverse to exit my driveway. I placed the car in Park and while the engine was running I exited the car. Upon exiting the car, the car immediately started to roll forward and crashed through my garage door leveling it to the ground. The car continued moving forward into the garage and came to a stop blocked by built in shelving at the back end of the garage. I could have been injured had the car started to roll while I was exiting the car or had some been in front of the car. No warning lamps or messages prior to the incident. The car has a safety feature if moving in Drive or Reverse and the driver door is opened the car shifts into Park. That feature failed. The car was inspected by a Hyundai dealer and claim no error codes found...

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.

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.

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...

2023 Hyundia Santa Fe bought brand new from the dealership. During the course of the last month and a half the vehicle has done things with unknown origin. The panic alarm will randomly go off when the vehicle is turned off, no one is in it, or even near it. By locking the vehicle with the remote, the alarm will tend to go off about 20-30 seconds after the vehicle is locked and will sometimes not stop until the vehicle is restarted. The transmission will shift very roughly almost to the point that it feels like you are driving a manual transmission vehicle. The transmission lags in gears between 60-70 miles per hour and you feel a very rough back and forth shifting with in the transmission. Next the emergency break would engaging and then not releasing or reengaging when parked on a hill, flat service or anywhere. The break...
