The FAWS Forward Assistance Warning System incorrectly identifies a "sleepy driver" and turns off Adaptive Cruise Control. FAWS has a dozen triggers that will cause this system to incorrectly alert the driver that his eyes aren't looking at the road and it turns off ACC. The FAWS has a turn off switch but it does not turn it off. So, without this safety feature of Adaptive Cruise Control, the driver just gets constant alerts to stay alert. Hyundai claims it is working "as designed" and has a suggestion to invest in specific sunglasses, or not be taller than 6'1" so the eyes can be detected, or don't wear a hat. Seriously, these are in the manual.

All warning lights illuminate and the dashboard showing the speedometer shuts off while driving as well as the heads up display. You have no idea how fast you are going or if you are have any warning lights.

- Fort Worth, TX, USA

My instrument cluster goes off/on intermittently causing a safety issue (I'm unable to see how fast I'm driving etc). The problem has happened to me everyday for the last 1.5 weeks, however the dealer has had the car for a week now and claims they can't replicate the issue to get the code to order the part (I have filed a complaint with Hyundai). I want to go on record as this is not a recall with hyundai yet, but I am aware it is a well known problem with 2025 Hyundai Tucson's according to a North America Facebook page I belong to where we discuss various topics (positive and negative) regarding our cars.

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.

I was driving the vehicle at 30 MPH when the power to the instrument cluster, infotainment center and headlights went out for approximately 1-2 seconds before recovering. Engine maintained power and acceleration during this period. During blackout I was unable to view speedometer nor other instrument information.

This vehicle is a pile of hot garbage. Front end collision system slams on the brakes when you are not even close to hitting something in front of you plus it will auto brake randomly but often. I was backing into a parking spot and someone walked in front of the car and it slammed on the brakes. Dealer says only way to fix this is to turn the entire safety system off. The coffee break warning has zero rhyme or reason and will go off 10+ times in a trip even though I am not distracted and use my turn signal changing lanes. Dealer states there is no way to turn this off. Dashboard randomly flashes and goes dark along with all lighting in and outside the vehicle. Dealer was unable to duplicate the problem and returned the car with no fix. Drove the car in the rain for the first time and dashboard came up with a ton of errors and crash detection turned off. This is new and will be taking the car in for this and is now the reason I am filing another complaint. This vehicle is NOT safe and can be very scary to drive because you don't know when it will just take over for you.

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.

Was driving at night and my lights went off and the radio turned off and right back on a second later. It-??s like the system rebooted. Drove fine.

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.
