The Heads Up Display and Dashboard randomly go blank for up to to 20 minutes at a time. During this, all alert warnings appear on the dash, no turn signals work, no sensor warnings alarm - no warnings of obstacles, no miles per hour are visible.

My 2025 Hyundai Tucson had approximately 150 miles when the forward collision warning system has started to provide false warnings. The first event happened as I was pulling out of a parking lot where there was a dip in pavement between the lot and road. The dip in the pavement was interpreted as an object about to cause impact so my car automatically applied full braking. I almost got hit from the car behind me who was not expecting me to stop. Now my car has 406 miles on it and I routinely receive warnings about collisions due to nearby cars doing U-turns or cars which I will definitely not hit. A few times it has applied braking which has almost caused several accidents from cars behind me not expecting me to stop.

The message “Consider taking a coffee break” will pop up just 15 minutes into a trip. This message beeps prior to flashing on the screen which causes us to take our eyes off the road to determine what is beeping and continues to “alert” us often during our travels. Hyundai has not provided a way for this warning to be deactivated. Hyundai has way too many messages beeping and appearing on the screen that causes distractions and has not provided a way to turn them off. As for the speed control, my ophthalmologist suggested I wear dark sunglasses due to issues I have in bright sunlight. The speed control will actually turn off if I wear dark sunglasses because the onboard camera cannot see my eyes. Also, the speed control will turn off if I’m making a turn and my arm gets in the way of the camera. This is extremely dangerous that the speed control just stops. We also will get beeps and a message on the screen if the camera cannot see our eyes, even when we are looking straight ahead. Again, this causes us to see what is beeping and what the message says. This is a distraction that causes us to take our eyes off the road. Terrible design.

My entire dashboard goes black and I lose all directions and functions in car. It happens when driving often. Additionally after taking to dealership, it's getting worse. Now warning lights come on and stay on such as master warning lights, batteries, power steering, etc. AC shuts off, the car misses out when driving between 25 and 30 mph. The dealership told me it's not safe to drive.

Vehicle: 2025 Hyundai Tucson SEL Approximate Date of Incident: [XXX] Description of Problem: While driving at normal speed, the dashboard display and exterior lights suddenly turned off, then reset. The speedometer and warning lights disappeared, then reappeared after a few seconds. This has happened once and I am concerned for my safety, especially if driving at night or in traffic. This issue has been reported by several other owners online, and it appears to be a widespread electrical or software fault. I am requesting that NHTSA investigate and Hyundai issue a recall or fix.

Several times now the Forward Collision Safety has activated and the car came to an abrupt stop. The car in front of me was braking and I was lightly tapping the brake pedal when out of nowhere the car started shuttering and came to a complete stop. This definitely scared me and I was relieved that the car behind me did not rear end me. I was not going fast by any means and I did not slam on the brakes as there was no need to. The Forward Collision is not a safety feature. This is a real problem and now I am scared of this braking design. I now deactivate this feature every time I turn the car on because there is no way to permanently dismantle this. Hyundai needs a recall to correct this.

On two occasions, the dash lights kept blacking out, along with the Heads Up Display. On my way to the dealer for a maintenance appointment, all of the emergency lights came on and would not go away. After parking at the dealer service center, I told my service rep what happened, and when she restarted the vehicle, the lights were still on. I was immediately given a loaner. After making the repair, the mechanic asked to keep the vehicle to drive for a few days to make sure the problem didn't come back. I know these problems can reappear, even after they are fixed. I don't want to drive the car if the safety lights are all illuminated, but I also don't want to be stuck someplace without transportation.

On Friday, [XXX], around [XXX] PM while traveling home my dashboard lights on the instruments panel and windshield pop up display were out, then back on, then out again, and then back on. On Saturday, [XXX], I traveled to another area about an hour away and all was fine, but on the way home it went out at least 12 times. Sometimes the dashboard light would come back up but not the pop-up display. When these go out I can not see my speed or any alerts that may possibly come up.

Subject: Ongoing Electrical and Safety Issues with 2025 Hyundai Tucson Limited Complaint Description: I am reporting a recurring and serious safety issue with my 2025 Hyundai Tucson Limited. I am the original owner and purchased the vehicle brand new, directly off the truck. It has now been to the dealership four separate times for the same persistent “Check User Authentication” electrical issue. Most recently, the driver display screen went completely blank while driving and flashed a green “No Signal” warning. This made it impossible to see speed, warning indicators, fuel level, or other critical driving information. Losing all visibility of this data while in motion is extremely dangerous and creates a serious safety risk. The dealership first said it was caused by loose coax cables from the factory, but the problem continues. I also experienced a sudden, complete electrical failure while driving. The instrument cluster and infotainment shut off, speakers went dead, and all charging ports lost power. The Head-Up Display (HUD) also failed during this same event. Restarting the car temporarily restored function, but the failure happened randomly and without explanation. The air conditioning system now loses power and restarts while driving. The dealership has had the vehicle for over a month with no resolution. Hyundai corporate is involved with multiple case numbers, but no permanent fix has been found. The most alarming event was when every major dash warning light came on at once: ABS, Power Steering, Traction Control, Stability Control, AFS, EPB, and Battery. These lights stayed on even after shutting off the vehicle and fully drained the battery. These repeated failures pose a serious threat to driver and passenger safety. I request that NHTSA investigate these issues, as they may affect more 2025 Tucson models.

Every time there is morning condensation/dew or rain, my front collision warning does not work. A notification pops up, the symbol comes onto the dash and it takes a good 3-5 minutes depending on the severity of the weather to have the symbol and notification go away and work. Also, 98% of the time when my car was preset to turn on, the emergency brake automatically engages every time I get into the drivers seat.

Consider taking a break (coffee cup icon) continues to notify even if vehicle is correctly in lane. MAJOR DISTRACTION, have to constantly check instrument cluster. Even with lane assist OFF, issue still continues.Hyundai needs to upgrade software. On 2025 Tuscon sel model no way to turn notification off. On a 6 hour trip,notification went off every 4-5 minutes on interstate driving.

The forward attention warning system uses a camera on the steering column. It goes off constantly while wearing my required glasses. Hyundai nor the dealership will turn off the sensor. There are over 10,000 complaints for this issue and Hyundai will not correct the issue. The system will automatically adjust the speed and brake in the vehicle without the driver. I almost had a wreck yesterday when it shut the car down when the camera couldn’t see my eyeballs while wearing my glasses. Something needs to be done. I’m thinking of filing a lawsuit against Hyundai as a class action. Please advise if you have any suggestions. Thank you

The Driver Attention Warning system goes off very often - every 10-15 minutes. The warning is startling and makes one take their eyes off the road to ascertain the cause of the warning. There is no voice message - just a series of beeps. According to the dealer the DAW cannot be disabled by the owner.
