I was riding on a suburban street and ran over a branch I did not see due to rain and darkness. I went back and looked at the incident and the branch did not seem like it was that big but I quickly lost power and my car stalled and I could not get it restarted. I later found out that that branch took out my hybrid battery connection under the car which rendered the car useless. It is a 5000 fix. I don't know why such an important part is exposed under the undercarriage of an AWD SUV. I was traveling at 27 MPH. If I had been on a highway it would have been very dangerous to have stalled out so fast. Once it was stalled the battery drained very fast from me running my hazards so that the tow truck driver had to jump it to get it to go from neutral to park and my parking brake is electric so I couldn't activate the parking brake either. I would also like to say that the headlights on this car are severely underpowered.

I tried to open the doors of my locked vehicle with the key fob and there was no response. I tried several times and nothing happened. I called AAA and they opened the door with my valet key and was able to pop the trunk. He checked the battery and it was working fine. He then noticed that the wire connecting the battery to the fuse box has melted at the point of contract with the fuse box and actually melted part of the plastic fuse box. There was nothing he could do, so I had to have the car towed to the dealer. I was lucky that the total meltdown of the electrical system did not occur when I was driving or I would not have been able to see any of the controls on the inside of the auto and not be able to use the gear shift to put the car in park.

The Forward Attention Warning device located on the steering column (camera) cannot be disengaged. This device does not allow me to wear dark or polarized sunglasses, which I need since I have eye issues. This is a safety issue for me and others, especially since I am [XXX] [XXX] and there are times when the visor doesn't cover the sun. You can 'disengage' it in the Driver Assistance settings but it does not stop the warnings nor does it stop it from disengaging your cruise control. If you look to the side of the vehicle, look up to pull the visor down, or wear polarized or dark sunglasses, it will also shut off your cruise control. I have taken the vehicle in to the Gainesville GA Hyundai and told them about this issue but they have said that there is no fix for this. BTW -- there are a bunch of posts on Reddit about this issue. This problem isn't a failure of the system, it is a design flaw. I noticed it on the day I bought the vehicle. Now, it is an annoyance to the point that I am looking at buying a new vehicle. I have only had the vehicle a year....not happy.

My vehicle was in for repairs at both a collision shop and a dealership following a minor accident. When I got the vehicle back, I found that the seat controls were not working, preventing me from moving the seat backward or forward. During a test drive, the car lost power despite the gas pedal being fully pressed; it wouldn't accelerate and then suddenly jerked forward. This could have caused an accident if I had been on a busy highway. Further testing revealed an abnormal noise at 1500 RPM in multiple gears. The vehicle has been towed back to the dealership, but there's no word yet on when it will be fixed. Hyundai has been contacted multiple times, as the car has been awaiting parts and undergoing repairs for over four months. They don't seem to be taking these safety issues seriously nor helpful in resolving the issue.

The vehicle has a digital instrument panel. Today the instrumental panel started flickering, sometimes all warning lights will flash, and then the panel will go completely black/blank while driving. Sometimes a red "NO SIGNAL" warning will flash across the screen. When this happens, there's no speedometer, engine temperature, or any information about the vehicle. This vehicle is 1-month old and has about 1300 miles.

The media screen console part of my 2024 Santa Fe has been glitching since July. Dealer has already looked at it and said there’s nothing to fix… now the screen flickers AND the audio glitches over and over the same few seconds.. then turn the car OFF and the audio stays playing over and over. Cannot turn off the media console or adjust volume. Screen goes out when using backup camera. I mostly have videos of these issues as you can’t tell in photos what’s wrong.

The digital gage cluster went black on my 2024 Hyundai Santa Fe Calligraphy (AWD) while I was driving on September 5, 2024. There were no prior warnings or indicators to alert me that anything was going to fail/not operate properly. I was entering a school zone and could not determine what speed I was traveling at to ensure that I was not moving too fast and endangering children, as well as walking parents; I pulled over and activated my Heads-Up-Display (HUD) to see if I could utilize it to safely continue my journey. I was able to use the HUD to know my speed. I initially had the HUD turned off because my daughter, who is a new driver, said that it was distracting to her. This occurred first yesterday. I thought that it may have been due to my system conducting a software update, but the issue appears to be intermittent. It sometimes comes back on, but it only remains on for no more than 10-15 minutes before going black again. Since it is a new vehicle and under warranty, I scheduled an appointment with the local Hyundai dealership the same night the issue first occurred to have the problem evaluated. When I arrived the next morning I was told that it would take about two (2) weeks for it to be diagnosed!?! I then went to a friend, who is a certified mechanic specializing in electronics, to take a quick assessment. She didn't discover anything during her observation, but decided to check online to see if there were any reports of this issue occurring prior to my incident. She found a technical report stating that the issue is known and probably caused by a wiring diameter issue that causes the digital gage cluster to intermittently go out and come back on. I believe that this could be a serious condition in certain situations. Besides not knowing your speed, you don't know if a turn signal is activated, how much fuel you have left, engine temps, oil pressure, tire pressures (TPMS), etc.

While I was driving, my new 2024 Hyundai Santa Fe suddenly experienced issues with the digital dashboard panel and a loss of speed. The dashboard went haywire, and my speed dropped from 60 mph to approximately 25 mph on the highway. The vehicle also struggled to accelerate from a standstill. After shutting off the vehicle and waiting a few minutes, the dashboard appeared to reset, and everything returned to normal. I immediately returned the vehicle to the dealer, but they could not find any issues as no codes were displayed. The abrupt decrease in speed while driving is a significant concern, as it could have resulted in a rear-end collision on the highway.

When driving the cluster panel with speedometer etc goes black for a bit and then comes back on. Also, all the warning lights will come on sporadically at the same time and stay on for a few seconds then go away, or just stay on until car is turned off. Heads up display also goes away and sometimes can't even locate in their settings area. After about 10 min of my phone being on wireless charger it gives me a warning message that my phone is getting hot and to remove the phone. Bought vehicle new on April 13th and this all started within the first week and continue.

16 warning lights came on. Blinkers are t working, side cameras not working and many other features. Then the check engine light came on.
