2025 Hyundai Tucson

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 contact owns a 2025 Hyundai Tucson. The contact stated that while driving and attempting to slow down, the Forward Collision Avoidance: Automatic Emergency Braking system activated, bringing the vehicle to a complete stop in the middle of the roadway. The vehicle returned to normal functionality, but the failure became a regular occurrence. The vehicle was taken to the dealer, who were unable to duplicate the failure. The vehicle was not repaired. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA Hotline for assistance. The failure mileage was 1,200.

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
