I have had two incidents with this vehicle (that I have owned for less than 90 days) that have raised safety concerns. Both involved the loss of all information on the "instrument panel" AKA dashboard. In the first (August 18, 2025), all of the warning lights came on, then the screen went dark - there was no information on the two screens and no head's up display. This happened while I was on the highway doing about 65 mph. After I was able to pull over safely, it took several attempts to get the vehicle started again and in gear. I took it to the dealer the next day and they were unable to replicate the issue and saw no codes. The second episode occurred yesterday (9/6/25). This time the screen went dark except for a large red warning "NO SIGNAL". The screen came back after a few moments; I am taking it to the dealer tomorrow. Both of these involved losing all information as to the speed of the vehicle - which I believe is a safety issue. Both of these issues have also been reported by others on Facebook ("Hyundai Owners") since late last year and it appears to be some sort of electrical issue but there has been no TSB or recall by Hyundai yet.

Heads up display and gauge cluster will intermittently flicker and/or reboot. When gauge cluster comes back on it will sometimes have all warning lights stay on. Have had it happen once where gauge cluster rebooted and then flashed "No Signal" while repeatedly rebooting. Both HUD and Gauge cluster do shut off together sometimes so I am no longer able to see my speed when that does happen

Instrument display and head up display go off and on at random times. Occasionally both are off at the same time so I can not see how fast I am going or use the video feed when signalling to turn. At times, all warning lights are on and do not go off so I am unable to tell if there is a problem with the vehicle.

My HUD was going off and on, especially on bumpier roads. This could happen several times on a drive. At least once, when the HUD went out, the dash lit up like a Christmas tree (all the warning lights came on), and a couple times it went totally black. I took it to the dealer and they diagnosed a bad head unit, and am awaiting parts.

Main dash (with speedometer and other driver notifications) and HUD went black. Blinking "No Signal" on 7/27/2025. Came back on after extended power off, but is flickering in and out when I go over a bump. All warning lights will light up, or the screen will go blank with "No Signal" or restart as if I had just turned on the car. HUD comes in and out. Infotainment is working fine.

While driving, my entire dash will go black. At times, all warning lights will also light up. There is no way to know how fast I am going since the display shuts down. Heads Up Display also goes out with warnings as well. With all warning lights coming on, there is no way to know if there is truly an issue with the car. The car was taken to the dealership and the cluster was replaced. This did not fix the problem. The car is now back at a dealership with no answers. I do have a case opened with Hyundai as well. Case # 41048985. I am a part of a Facebook group were an additional 19 people have also said they have experienced the same issues. There seems to be no real concern from Hyundai. Safety Risk - speed visibility, warning lights, overall safe operation Problem as been confirmed by the dealership No issues with the vehicle prior to this

There are several electrical issues occurring that have put me in danger when driving. First the screen both on the windshield and the speedometer screen randomly go out completely and I have no idea how fast I am going or any other important features like how much gas my vehicle has, if the vehicle is over heating. The forward/ break feature has gone off multiple times and the vehicle has stopped in the middle of traffic and the freeway with zero warning and with several car lengths between me and the car in front of me. Almost hit from behind when this happens and has put the vehicle in park on the freeway. Steering wheel has jerked to the side when driving making the vehicle almost hit curbs and other vehicles. Has come back to my vehicle that is off and locked and the ac has been running causing the engine to be hot. All the warning lights have turned on and won't go off even after stopping and restarting the vehicle. The vehicle is currently at the dealership with them having to answer to the problem, stating hyundai is aware of the issues but does not know how to fix it. I bought the car in April 2025 and there is just under 2800 miles on the vehicle.

I purchased a brand new 2025 Hyundai Tuscan and with 984 miles I had an issue which first started when reversing the SUV into my garage. December 9th: When first starting the vehicle, all warning lights came on the dash. The ABS stating an issue with the braking system. I experienced a dead pedal and no power steering. After restarting the car all the lights went off and the car returned to normal. Code: DTC C165686 and DTC C162587 December 10th Error: Check driver assistance system While driving the vehicle which had no errors on start, the error came up again but this time power steering was available and the brake pedal appeared to be working. Originally, the Hyundai dealer would not be able to assist until the following week but after calling them and expressing safety concerns they immediately took the car and put me in a loaner. Code: DTC C165686 and DTC C162587 It’s Jan 3 2025 and the vehicle has been waiting for a replacement hybrid battery. The manufacturer told the dealership weeks ago that the error is due to a bad hybrid battery.
