What 266 owners told NHTSA about the 2025 Hyundai Tucson Fuel Cell

MULTIPLE WARNING LIGHTS ON THE DASHBOARD, INCLUDING SRS , TCS, ABS , ALL LIGHTS STAY ON EVEN AFTER TURNING THE VEHICLE OFF. SYSTEMS DON'T WORK, SUCH AS LANE DEPARTURE, COLLISION AVOIDANCE & ABS DON'T WORK. SPOKE W/ KOEPPEL HYUNDAI, MENTIONED THE ISSUE, BUT WAS TOLD THAT THAT ISN'T PART OF THE RECALL, THEREFORE THEY WILL NOT ADRESS THE ISSUE. IT'S FRUSTRATING , DON'T FEEL SAFE DRIVING THE VEHICLE. WILL TAKE LEGAL ACTION IF ANY ACCIDENTS WILL HAPPEN DUE TO AN ISSUE THAT THE DEALER IS REFUSING THE ADRESS.

Doesn't slow down properly when I step off from gas pedal and try to stop at traffic light/stop signs and before making turns. It barely reduces average 2 mph for whole block. Lets say when I step off from the gas pedal at 25 mph, the car reduce the speed to about 23 mph when it's so close to light/stop signs and right before making turns. It seems like there is no 1st gear, just 2nd gear is the lowest. Always I have to brake harsh before light/stop sign/ making turns. I've been driving for 45 years in NYC but I can't get used to this dangerously weird driving situation while driving the 2025 Hyundai Tucson. I have driven the 2023 Hyundai Tuscon before as well but I have not had this issue until now with the 2025 model.

My car abruptly stopped due to the emergency braking system when the car in front of me braked (hard) but I had more than enough time to stop without having the emergency braking system engaged. Due to this, the car behind me hit me from behind damaging my bumper, trunk, and back lights

During the winter, my car would activate the forward collision warning and automatic emergency braking while I was driving when there were no other vehicles in front of me or even around me. It happened several times over a few day timespan, at the time I thought it was because I had gotten a car wash when it was colder weather and maybe the water had affected the system but now I see that there is a recall for this same issue.

The underbody shield is held up partially by plastic nuts that get loose casing the shield to rattle at speed over 60mpg. I read multiple reports from other owners on reddit. Tightening these plastic nuts help ressolve the rattle temporarly, but the nuts are flimsy and keep spinning. You can't really tighten them well. A good remedy from Hyundai would be to replace these flimsy plastic nuts with metal ones that stay tightened and secure the underbody shield in place. Dealer wasn't helpful and wanted to charge $200 just to look at it

The rear seat belt is stuck. The vehicle was only 3 months old when it was noticed. Originally, I thought the constant beeping about the rear seat belts was due to this error, but it is 2 separate issues.

​Before I owned this car, I used to get so frustrated whenever I was driving behind this type of vehicle because the rear blinkers are mounted so incredibly low in the bottom bumper that you can't see what the driver is doing. Now that I actually own a Hyundai Tucson, I feel completely responsible for the drivers behind me. Because I know how low my blinkers and reverse lights are, I have to turn them on way before I actually turn, and I'm always worried someone will hit me when I'm in reverse. On top of that, my friends who drive behind me constantly tell me how bad it is and how hard it is to see my signals because of how low they sit.

The forward collision automatic braking happens randomly and for no reason causing immediate and complete stops in the middle of traffic. It whips the head forward as if a crash had occurred and causes drivers to the rear to have to suddenly brake to avoid collision. Ive had it occur multiple times since purchase with the most recent being this morning in the middle of a roundabout. I know I can disable the system but 1) that's also a safety risk and 2) it turns back on every time I start the car which is unacceptable. Ive asked the dealership about it and was told that it cannot be disabled. I already have the sensitivity turned down as much as possible and it still is happening. This issue makes an otherwise wonderful vehicle almost uunrivaled. When this happens there's no warning before the sudden braking. It also will randomly just slow speed down for no reason and with no way for the driver to stop it. Something needs to be done. Fix the system and make available a way to disable it without it auto turning back on. Im fed up.

Forward collision assist is dangerous. It engages when not necessary and has almost caused several wrecks by slamming on the brakes. There needs to be a way to permanently disable and not have to pick through a series of menus every time. Also, lately I feel like I’m fighting the lane keep assist when I’m on the highway, and it tries to move when not necessary.

While driving the vehicle information system (speedometer, tach, fuel, etc.) goes dark for several minutes. It comes back then it goes out again.

NHTSA ODI 11738999

3 incidents of same braking component. Once while exiting a parking lot, the car slams breaks so hard while accelerating that car slams to hard stop with no warning. Once while driving through an intersection brakes engaged for no reason. Once after stopping at Red light, then when moving with traffic, car stops so hard with no warning that we were almost rear ended and seat belt left marks and bottom of car seemed to hit the ground. These violent automatic breaking events are scary because for no reason or cause and no warning the car suddenly hard brakes. Fear of being rear ended or car flipping from such sudden and hard breaking. This incident has not been inspected although the car is current on all maintenance and has been recently in to car dealer for oil change.

On 5/14/2026, while driving southbound on I-95 with my pregnant wife and young daughter, my 2025 Hyundai Tucson (approx. 7,500 miles, purchased new 10/2025) experienced multiple critical safety failures. Two days prior, the heads-up display (HUD) intermittently failed to activate. On 5/14, traveling at 65-70 mph near [XXX] , the brakes auto-applied without driver input. Simultaneously, the instrument cluster and HUD went completely black, eliminating all speed and vehicle status information. This recurred intermittently. Near [XXX] , the brakes auto-applied with full force, locking all four tires and bringing the vehicle from approx. 70 mph to a complete stop on the active interstate. Two trailing vehicles spun out and left the travel lane to avoid rear-ending us. A multi-car pileup was narrowly avoided. The vehicle was taken to Pearson Hyundai in Midlothian, VA. They diagnosed and replaced a faulty wiring harness. Immediately after the repair, driving northbound on I-95 back to [XXX] (5/16), the lane keep assist/lane departure system began pulling the steering wheel into the adjacent lane without driver input, repeatedly and unpredictably at highway speed. The dealer repair did not resolve the all defects. Within a three days this vehicle exhibited: (1) total instrument cluster/HUD failure, (2) uncommanded emergency braking at 70 mph causing two other vehicles to take evasive action (3) uncommanded steering input into an adjacent lane. These failures created immediate risk of serious injury or death. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

There have been two instances now within about 4 months where my 2025 Hyundai Tucson's emergency braking/anti forward collision system has engaged completely unnecessarily, slamming on my brakes and almost causing the car behind me to hit me. In both cases there wasn't a car in front of me within at least 100 feet. In both cases I was going probably 30-40 miles per hour.

NHTSA ODI 11738046

The FCA engages in situations that are not dangerous. There is a slamming of the breaks which causes items in the car to fly off the seat and nearly cause the cars behind me to rear end the car. This is a dangerous situation and has happened about 6 times since we purchased the car less than six months ago. There is not a way to permanently disable this supposed safety feature.

NHTSA ODI 11736725

The forward emergency braking system on this vehicle is a hazard not a safety feature. I have almost been rear ended 3 times because of it and have had my neck and back hurt from the quick sudden stop! I was not even at risk of getting into an accident! This feature needs to be permanently disabled! I still owe 30 payments on this car but will be getting rid of it if i can't disable this permanently.

Vehicle is 2025 Hyundai Tuscon purchased 12/31/2025. On April 18th, as I was backing into my garage i noticed that I could not see through the right side end window. On closer look I noticed that the glass was shattered without any spots of particle hit or point of impact. I stopped and took pictures, took the vehicle to Potamkin Hyundai and the service guy also took pictures. I went back on April 21 to see the service manager who also took pictures and advised me to give them some time to review. After about 1 week, I got the message that the request for replacement under Manufacturer Warranty had been declined and that I would have to replace this on my own.

What component or system failed or malfunctioned, and is it available for inspection upon request? Automatic braking system brakes for no reason when I am not near any cars traveling at high speed or even when I am already at a complete stop or moving very slowly but not anywhere near hitting the car in front of me. This has happened multiple times since I leased this car in July 2025 and it seems to be getting worse. I had a 45 min drive home today and it happened about 7 times all for no reason. How was your safety or the safety of others put at risk? It slams on the brakes unnecessarily and the cars behind me almost rear end me. This has happened on residential roads and highways. Has the problem been reproduced or confirmed by a dealer or independent service center? I just called to take it in. They seemed to have no idea what I was talking about. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? not yet but I am taking it in asap Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? NONE

The cars speedometer screen and radio screen go black and sometimes flicker on and off. This makes it impossible to see the speed. Also the car stalls sometimes when this happens in traffic. The autonomous braking applies the brakes even when there is a large distance from other cars and objects to the point where it has almost caused me to get into an accident on numerous occasions. The driver attention alert comes on and off over and over again even though I’m fully focused on driving and well aware of what is going on and this sometimes happens in a sequence where all of the warning lights illuminate on dash. Sometimes all of the warning lights display on cluster after it goes black and then car says to shift to park when display goes back on causing safety concerns for me in traffic. In addition my sunroof glass is making a loud noise like it’s going to crack.

The contact leased a 2025 Hyundai Tucson. The contact stated that while driving at 40 MPH, another driver cut her off while in an intersection which activated the emergency brake system. As a result, the contact was hit from behind by another vehicle. The air bags did not deploy and the seat belt failed to secure the contact and thrusted her forward. The contact did not seek medical attention but days after the accident, the right side of her neck, right lower shoulder blade, right inner thigh, right side of her chest, left side sciatica, lower right abdomen, and lower back. The authorities arrived at the scene and a police report was filed. Despite the failure and the damage to the vehicle, the contact managed to drive the vehicle home. The manufacturer had yet to be notified of the failure. The vehicle had yet to be diagnosed or repaired. The failure mileage was approximately 15,900.

I was on the freeway about 2 minutes and the car flashed a red warning then slammed on the brakes and I flew forward. No cruise control and no buttons hit or anything automatic. Another time,  I was merging to freeway on ramp (with 2 lanes merging and going to freeway). I was on the left right lane towards the on ramp and another car came speeding next to me on other the on ramp right lane. All of a sudden, my Tucson says emergency braking for about 1 to 3 seconds. slamps the brakes. I am not sure if the other speeding car made a sensor think I was going to merge into him,or him into me, or the sensors didn't detect the lane markings. It's my daily route to this ramp and it has not occurred in the past. These emergency braking incident has happened several times (4-5 times in a month) to me, usually during a highway drive similar to those above. I have to turn off the forward collsion to stop this happening and it comes back on everytime when the car starts from a off.

On at least three occasions, the forward collision system incorrectly determined there was an imminent collision when a car or truck was simply coming over into my lane. The Tucscon locked the brakes, bringing the car to a full stop in the middle of high-traffic roads even while the car in front was pulling away. I was unable to give the car gas to continue driving forward. On two occasions this was on an interstate, going from almost 70 mph to stop when there was no car or obstacle in front of the car. It created a very dangerous risk of being rear-ended. The car did display the message "Collision Warning" on the instrument panel, emit an audible alarm, and shook the steering wheel.

Had an issue with driver assist radar when in complete control. Until you’re not! Brakes lock up skidding tires and causing seat belts to lock up. It happens so suddenly it scares you to the point of heart attack. This has happened: merely backing out of driveway, when accelerating in your lane with car in turn lane beside you turning right. And most recently on FL Turnpike while in stopped/slowed traffic due to emergency vehicles trying to get to scene of Naples wildfire. When I accelerated as traffic resumed at slow speed the car locks up brakes, squalling tires and slewing sideways. It startled me so much my heart was racing and I didn’t know if the car was still running or not. There was an 18 wheeler coming up behind and I was frozen not knowing what to do next. I don’t know if sensitivity can be adjusted or what it needs but my heart can’t take many more of these incidents. I will report to dealer as well. I know there is a Reddit thread about these same issues that my daughter found on researching this issue.

I have about 13,500 miles on my 2025 Tucson Hyundai. The screen with the speedometer and HUD constantly turns on and off so you have no idea what speed you're going, if you need fuel and several other readings. It has been repaired once. Took it back to the dealer a second time, they said there was no issue. It is still doing it, and I am making an appointment to return it to the dealer again for service. I drive on a very busy interstate daily to and from work. I feel this is a safety issue. I googled the problem and many accounts of this happening to other owners can be found with the same issue. I think Hyundai needs to issue a recall and make sure their engineering department finds the source of this and corrects the problem before someone is in an accident or just stranded on some highway.

The display on the dashboard that includes the speedometer and other information goes completely blank. So does the heads-up display on the windshield. This could occur at the same time or individually. It may last only a few seconds or for several minutes. This has happened since I bought the car about 1.5 years ago. I've had it to the dealership and they have noted the problem but have not been able to fix it. I know that Genesis, which is part of Hyundai has had recalls about this problem, but so far Hyundai has not. Since it involves a loss of the speedometer, I think that it is a safety problem and should be addressed. It happens almost every time that I drive the car.
