Multiple warning lights on the dashboard, including SRS , tcs, ABS , all lights stay on even after turning the vehicle off. Systems don't work, such as lane departure, collision avoidance & ABS don't work. Spoke w/ koeppel hyundai, mentioned the issue, but was told that that isn't part of the recall, therefore they will not adress the issue. It's frustrating , don't feel safe driving the vehicle. Will take legal action if any accidents will happen due to an issue that the dealer is refusing the adress.

The cars speedometer screen and radio screen go black and sometimes flicker on and off. This makes it impossible to see the speed. Also the car stalls sometimes when this happens in traffic. The autonomous braking applies the brakes even when there is a large distance from other cars and objects to the point where it has almost caused me to get into an accident on numerous occasions. The driver attention alert comes on and off over and over again even though I’m fully focused on driving and well aware of what is going on and this sometimes happens in a sequence where all of the warning lights illuminate on dash. Sometimes all of the warning lights display on cluster after it goes black and then car says to shift to park when display goes back on causing safety concerns for me in traffic. In addition my sunroof glass is making a loud noise like it’s going to crack.

The dashboard and heads up display intermittently goes on and off. All warning lights are on when the dashboard comes back on. It goes off long enough to not know how fast you are going. Hyundai has this as a known issue for Limited trims of the Hyundai Tucson yet they only tell you to take it to the dealer for the vehicle to be fixed. Customers have taken their vehicle back to the dealership after the dealerships stated that the issue was fixed because the issue happens again a few days later. This is a safety issue that needs to be addressed.

Attention warning... If you wear glasses that transition to dark, the system shuts down the car on cruise control. Numerous warning lights and bells. Take a break warning and sounds continuously popping up on the screen. There is no way to disable the eyes forward attention system. You cannot wear sunglasses as it can't see your eyes. I use my cruise control all the time. But the system shuts it down. This happens on all 2025 Hyundai equipped with the attention system.

The following problems began 5 months ago, 8 months after purchase with about 4770 mileage and current mileage of about 7623: Multiple occurrences of Check Engine light coming on, sometimes setting DTC code, but often not setting code. Multiple occurrences of Crash Warning light coming on; It may have set a code or codes, but usually not. I think neither dealer was able to reproduce these 2 intermittent problems. Engine light, so far, has not occurred since it was traced to faulty connectors. As far as I know, the Crash Warning light has not come on since the dealer reduced front camera sensitivity. Also, for the past 5 months there has been intermittent, engine miss, skipping or cut-out. As of this writing it still occurs while driving and will lurch or buck if it happens under acceleration This is not frequent, but it happens erratically and it may happen only once or a few times in one day or several days between. This has not set a DTC code as far as I know; I think the following may be related to the skipping. Once, while coming to a stop, the engine stopped or almost stopped; it bucked when it happened, but continued to run. All warning lights came on for a second or two, then went off, except 3 warning lights and the warning triangle. Although the engine was running, the tachometer and speedometer read Zero. The engine bucked as I slowly drove into a parking lot, then I restarted the engine; it seemed ok, then. About 3 weeks later, while driving at slow speed, just as I took my foot off the brake and was about to accelerate, the engine quit. When the engine quit, the audible Crash Alarm went off with a message saying the engine was not running, press the start button. I started the engine, it did not have normal power. I stopped, restarted the engine and it seemed ok. I have been to the dealer several times because of these problems; dealer is still troubleshooting the last incident. This could cause an accident, especially if it occurs at a higher speed.

Control screen keeps going randomly blank, for different periods of time, putting the driver at risk, because the vehicle information, including speed, lights, wipers, basically everything is displayed in this screen. Sometimes the sentence NO SIGNAL shows up. I had experienced several scary situations, specially in freeways when raining, you have zero driving information. The car has been to the dealership service 4 times, with different tentatives of repair, none of which worked. The last time my car was at the dealership service for 25 days and after 2 days the problem was back, even worse. Sometimes all the lights of the control screen light up, with no reason and keep on even after the car is turned off. This is our only car and we need it, but the car is absolutely unsafe and unreliable. I refuse to leave the car for a 5th time, Hyundai has no idea what the issue is and obviously cannot fix it. The lane assist is also malfunctioning, sometimes the warning system doesn’t work properly. Twice the car emergency brakes stopped the car abruptly without a reason to do so (no risk of collision, no car or object in front ). One of those times the car behind me almost hit me, because the stop was abrupt and for no reason. I have many videos and pictures, but apparently I cannot upload the videos in this form. I have the paperwork, but Hyundai refused to refund for the vehicle. I highly recommend an investigation, Hyundai is getting away with a very serious problem and someone will get hurt as a result of these issues. Thank you for the attention.
