2025 Hyundai Tucson

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.

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.

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.

I leased a brand new 2025 Hyundai Tucson on March 15, 2025, with fewer than 10 miles on the odometer. Shortly after driving an additional 10 miles, the vehicle’s screen malfunctioned, displaying burn-in and becoming non-functional. This issue significantly affects safety, as it renders the backup camera unusable during operation. The vehicle was first brought in for service on March 17, 2025, but the issue was not resolved. Subsequent service attempts were made on March 20, April 9, and most recently on April 11, 2025. As of today, the problem remains unresolved. The vehicle has been in the service center for approximately 15 days since the date of purchase. In addition to the defective screen, the vehicle failed to start on one occasion, leaving me stranded alone in a parking lot, stuck in accessory mode with the brake locked. The car has also exhibited alignment issues, consistently pulling to the left while driving, which has required two alignments since the purchase date.

Battery issue does not resolved, had to jump-start the vehicle twice, leading to significant inconvenience as I drove nearly an hour each way to the dealership. This situation has resulted in lost work hours and has left me feeling mentally and physically exhausted. Despite my efforts, I still have not received a satisfactory answer regarding the problem
