2023 HYUNDAI SANTA FE Complaints

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 and dismissed any other information as provided in this report

Vehicle sun/moon roof exploded/shattered while driving on the highway with no apparent external cause. Sunroof was closed, driving middle lane, slightly below speed limit. Fortunately the material blind was closed otherwise the glass could have struck the occupants. Drove to manufacturer dealership who insisted it was a stone and not a manufacturer defect and to claim through insurance, which means a $1000 excess. I know this happens on various vehicles, noted on many forums.

Well i have this a year and the horn went a month ago. I also have a hyundai Kona 2022 and it has had the horn replaced twice. Its a common issue with hyundai and safety issue especially where we drive in a city full of new college students from out of town snd people make erratic moves and safety concerns. It is a required part on a car and now this will be the 3rd time i need to replace it

It started in April 2024. After the dealership performed an oil change we heard a strange noise whenever we accelerated. The dealership said it was either the transmission or the hybrid motor and both were on back order (usually an indicator that these parts are in great demand). After several weeks both parts arrived but they only replaced the transmission because that took care of the noise. A few days after we got the car back, we heard a clunking sound whenever we shifted. I tried to take the car to a different dealership but they said we had to return to the place that installed the transmission because bolts were missing. We went back to that dealership and they said no bolts were missing but they did need to be tightened. After that the clunking stopped, however, the next day we started experiencing other problems. The check engine and master system lights came on and the car would hesitate when accelerating. This was extremely dangerous when we were on the freeway and/or trying to accelerate from a traffic signal. Also, it had trouble shifting into reverse. The dealership said the codes were indicating the hybrid system battery needed to be replaced. The car has less than 20k miles.

One of the 2 horns has stopped working. After checking the Hyundai Forum website, I've found that one or both horns has suddenly went dead on not just Santa Fe's, but virtually all Hyundai models across the board. This seems to be a widespread defect. This is very dangerous because the cessation of operation is sudden and without warning (ie, no dashboard warning light). If there is a need for the driver to sound a horn in a time of danger there may be absolutely no way to give a warning.

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.

Driving at a low speed and blind spot warning light comes on, then all warnings light up and car loses all power and goes into limp mode. Engine light stays on, but will start back up after it is shut off, open and shut car door and restart. Engine light stays on. Has happened to me three or four times. In the past, the engine light will eventually go off before I can get it to the dealership. Hyundai said they couldn’t duplicate the problem last time it was taken in, so nothing could be done. Gives error code P063512 each time and says EMS which I assume means emissions.

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.

I was driving 70 MPH on highway and the AEB activated despite no other vehicles in front of me. Thankfully the car behind me was far enough behind that they could swerve out of the way, or it could have been a massive collision. Additionally the person behind me could have swerved into traffic Causing a massive accident. This is happened twice the other time I was going 50 miles an hour. I am afraid to drive this car on the highway now.

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.
