I was driving home tonight and while driving the car lost all power on the full screen and headlights. This is the second report of the same problem. It was like a blackout at two o clock in the morning. I couldn’t see the speed and the lights went out. It did come back on in immediately.

Two instances of the center screen malfunctioning. One was an intermittent blip of the screen turning black and then turning back on while driving. Additionally, during this same instance of the intermittent blip of the screen turning off for about 3 seconds, my headlights which are set to auto also turned off while I was driving at night and then blipped back on when the screen came back at the same time. Second instance, the center screen was black and never came on when the car was initially turned on and the screen remained black for the entirety of my drive until the car was fully turned off and then back on. Yes, this is available for inspection upon request. Safety was put at risk by losing headlight visibility at night highly increasing the chances of an accident as well as losing important carplay navigational directions on center screen. Problem has been reproduced as these issues both occurred within one week (the week of August 16-23, 2026). The vehicle has not been inspected. During the time of both events there were no warning lamps or messages that appeared.

This problem was observed about 1 month ago: While driving and headlights set on AUTO, during the day, and the light switch NOT on, the dashboard would indicate the lights were ON, for just a second or two, and would go off. At night with the headlights set on AUTO and the headlights ON, while driving, the headlights go OFF and ON briefly (1-3 seconds) causing a dangerous situation as visibility of road is lost. This condition was initially observed at night, after using the turn signals (left/right), but is now happening with greater frequency while driving without using turn signals. I Will schedule a visit with dealership to report/confirm problem.

The contact owns a 2022 Hyundai Tucson. The contact stated that the check engine warning light illuminated and was cleared; however, the warning light returned hours or days later. The dealer had cleared the check engine warning light approximately 15-16 times. The vehicle occasionally stalled while driving at various speeds. The dealer diagnosed the vehicle with terminal engine failure. The contact was informed that the fuel system needed to be overhauled, and the fuel injectors and caps needed to be replaced. The vehicle was repaired twice. The failure persisted after the contact had confirmed the diagnosis with a certified mechanic. The vehicle was returned to the dealer, who replaced the engine. The vehicle was parked for several hours, and the contact attempted to turn on the headlights, but the headlights failed to illuminate. While driving the vehicle, the vehicle hesitated several times.

While driving at night, the headlights on my 2022 Hyundai Tucson Hybrid shut off randomly, including when using the turn signal. The lights will turn off without warning at highway speeds, creating a serious safety hazard. Using the turn signal can cause the headlights to turn off, and sometimes using the turn signal will temporarily turn them back on. The headlight mode also changes by itself while driving (AUTO to OFF to ON to OFF). Additionally, when the vehicle is turned off, the headlights often stay on no matter what mode the switch is in. I have to restart the vehicle and manipulate the turn signal/headlight stalk multiple times to get the lights to turn off. This is a recurring and dangerous failure that affects nighttime visibility and safety for me and my family. No other electrical issues are present. This is available for inspection. Safety for my family and all others on the road put at risk as the headlights randomly shut off at night. The problem was reproduced by the dealer. The dealer quoted a $1,500 repair, but this a safety‑critical defect in the lighting control system.

On July 24, 2026, while driving on a marked city street with no vehicle, pedestrian, or obstruction ahead, the Forward Collision-Avoidance system on our 2022 Hyundai Tucson Limited AWD applied emergency braking on its own, three to four separate times, each lasting one to two seconds. Traffic behind us nearly struck our vehicle. My family was in the car. This is the latest event in a progressive electrical fault history. In June 2025, under warranty at 48,037 miles, a Hyundai dealer documented recurring multi-system warning cascades (forward safety, lane keeping, high beam assist, speed limit warning) and a failed auto start/stop system. The dealer's listed resolution was "battery voltage / replace battery"; their invoice records that no repair was performed. We replaced the battery at our own expense. The faults continued. In June 2026, the start/stop system shut the engine off at a red light and the vehicle would not restart, leaving us disabled in a live traffic lane. Power was only restored by cycling the hood release. Since then, TCM and ECU software updates and a battery harness replacement (our expense, approx. $1,200) have been performed. The faults persisted after these repairs and have now escalated to uncommanded emergency braking. Date- and time-stamped video and photographs exist for multiple events. Two Hyundai dealerships have not identified a root cause. Similar phantom braking reports exist from other owners of this model year. We no longer consider the vehicle safe to drive.

Good morning the problems I am having with my 2025 are very discouraging. Started October of 2025, my tire light illuminated stated the tires were low when they are all at correct specs when using an air guage to check. November of 2025 while driving at night the headlights suddenly shut off briefly then came back back on. January of 2026 while leaving work the transmission would not shift, held accelerator pedal to floor but could not go above 20 mph all the way home for 3 miles. April of 2026 the right side of navigation screen went completely black, shut vehicle off twice and on third restart the screen reilluminated. June of 2026 same thing with the screen going black. I have had my Tuscon at the local dealer here in my town for supposedly a repair that they state was a "coaxel cable" behind the dash that was fixed that was causing this issue. I also had the recall performed for the front view camera software update but it is still showing not completed. This is very frustrating to be having experiencing these kind of issues on this new of a vehicle. Clearly something is going on with the software or something and the dealer keeps telling me they are not finding anything wrong. I am a service advisor myself at a small independent shop so I understand the terms they are using but something needs to be addressed to correct the issues that I am having. It is scary when driving and the screen goes black or driving at night and losing the headlight functions. I would appreciate if somebody will look into this and reach out to me to get some kind of remedy for why this is happening. I am paying alot for this vehicle and to say I am satisifed is an understatement. I have purchased Hyundai as my choice of vehicle due to the quality, great warranties and good reviews from other consumers however I am seriously thinking of exploring alternative makes as I do not want to keep going through this. Plus the engine consumes oil. I have attached p/w for review as well
