2025 Hyundai Tucson

This vehicle has had numerous problems since I leased it. To summarize, at times the vehicle randomly shifts out of the ECO mode, usually into the SNOW mode. The engine has also raced, hesitated, bucked, rattled and vibrated when trying to change gears. Sometimes, these actions are subtle and sometimes they are borderline violent. This happens more frequently when the engine is cold. Additionally, the AEB system has activated a number of times while in stop and go traffic, even though the vehicle in front was moving forward. On at least 3 of these occasions, i barely avoided being rear-ended by the vehicle following me. The final issue that I have noticed is a problem with the odometer. It has appeared to work normally most of the time, but I have noticed times where I didn't think the odometer accurately reflected the distance I had traveled. I was able to synch the odometer with the trip odometer on a local road that I was quite familiar with. The trip odometer registered 1.8 miles while the odometer only registered 1 mile traveled. All of these issues happened multiple times and are intermittent. I have had the vehicle to Hyundai dealers on 5 occasions, and they claim to have not been able to duplicate any of the problems that I have been consistently logging in to a "diary" that represents a list of when I have noticed these issues. I have been in constant contact with Hyundai, but they promised to send out a factory rep, then reneged, instead relying on the local service techs. Said techs had the vehicle for nearly 2 weeks, but only drove it for 16 miles (until I called AFTER a determination was made and they hurriedly drove it an additional 22 miles to give the appearance of a more complete exam), using less than a quarter tank of gas. To me, this wasn't a thorough exam and appeared to be a cover-up to avoid having to buy back the vehicle. Note: these problems have occurred on multiple occasions, therefore the date below is the lease date.

The car in front of me, 8 to 10 feet ahead, slow down and turn on their blinker. My car slammed so hard on its break. It threw me and my dog forward. It never gave us a warning until it slammed. There was plenty of time for me to slow down, but also the car was partially already in the turn lane. There is then 223 seconds where my car will not move forward. I am a sitting duck to cars coming behind me.

Approximate date 10/7/2025. Driving 20mph clear daylight sunny conditions in right lane,another vehicle in left lane put on right blinker to merge in front of me into my lane. The merging vehicle was 3 car lengths ahead and had plenty of space to merge. Merging vehicle was only half way into right lane when without touching the brakes and no warning alarm the wheels locked up completely,skidding to a complete stop,almost got rear ended. 2 days later on 10/9/2025 same weather conditions while driving on highway the traffic was stop and go,speed 40mph. A vehicle ahead of me applied their brakes,no imminent threat, I placed my foot on brake pedal as a precaution,then brakes locked up so I pumped brakes thinking what else could I do? This did nothing,brakes remained locked until vehicle stopped. Almost got rear ended again. I can’t remember if any audible alarm or dash warning. These were the only 2 incidents with braking failure. Hyundai Dealer booked appointment but they could not find any issues with the braking system on 10/2025. Mechanic could not reproduce braking issue. When I picked up vehicle I spoke to the mechanic. He said “ if the braking issue occurs again please make another appointment. The salesman who I purchased the vehicle said “shut off the warning system”. Which I declined his offer. Thank you!

The Forward Attention Warning system performs erratically, frequently disabling the adaptive cruise control without warning. Even when it does emit a warning, which again, is erractic, the warning is barely audible. When conditions, such as grooved pavement or loud cabin noises, such as when a window or moonroof is open, the warning is completely in-audible. Similarly, the warning message displayed is not readable within the 0.5 - 1.0 sec (best estimate) that it is shown, as it is several lines of text - a distraction in itself. The disabling occurred during times when this ADAS feature is most value, cruising at highway speeds in heavier traffic - a time when automatic speed control and braking, along with maintaining a clear distance, are all invaluable to driver safety.

In October 2025, the center display screen in my 2025 Hyundai Tucson Hybrid began shutting off repeatedly while the vehicle was in motion. The screen controls essential functions including speed information, navigation, backup camera, safety alerts, and hybrid system data. When it shuts off, all of these features become unavailable without warning. The failure is intermittent and continues to reoccur. The component involved is the center display/infotainment system and may affect related radar and safety-system warnings. The dealer stated they duplicated the issue and reported that it was repaired, but the same display failure occurred again afterward while I was driving. The vehicle is currently with the dealer and is available for inspection upon request. My safety and the safety of others is put at risk because when the screen shuts off, I lose access to critical vehicle information. This has happened at highway speeds, including one instance where the display shut off approximately eight times within 20 minutes. In addition, the radar warning system has activated when no nearby vehicles were present, creating distraction and uncertainty. The problem has been reproduced by the dealership, documented by me on video, and reported to the manufacturer. The vehicle has been inspected multiple times by an authorized Hyundai service center and reviewed by the manufacturer’s customer service department. There have been no police or insurance inspections because the defect has not resulted in a crash, though the safety risk is significant. Warning symptoms include intermittent radar system alerts appearing without surrounding traffic. These symptoms began in October 2025 and have continued even after dealer repairs. The display failure persists and the vehicle remains unsafe to operate. P.S. I cannot upload video evidence as the website would not allow me and I have to start over.

The automatic braking was inappropriately applied while I was coming to a controlled stop on a 45mph stop light intersection. I was already slowing down and about 30 feet behind the car in front of me the Collision Avoidance warning starting going off, slightly applied brakes (to the additional amount I was already applying) then slammed on the brakes to a complete stop. There was some teen behind me who wasn't paying attention, and obviously no one expects the car in front of them to slam on their brakes 30 feet behind the cars in front of them, then plowed into back end of my car. This isn't the first time it's happened and I wasn't even at risk of collision as I was already slowing down in the other instances. But this time it caused an accident and injury. I am suffering from whiplash and possible herniated disk. The system is on the Late setting as well but is still dangerous to drive. There needs to be a firmware update or sensor recall, this is very dangerous!

The contact owns a 2025 Hyundai Tucson. The contact stated that while driving at an undisclosed speed on three occasions and depressing the brake pedal, the Forward Collision Avoidance system malfunctioned. The contact stated that upon depressing the brake pedal, the Forward Collision Avoidance system activated the Automatic Emergency Braking system excessively, causing the brakes to engage forcefully, and almost caused a crash on one occasion. The dealer was not notified of the failure. No further information was available. The manufacturer was notified of the failure and a complaint was filed. The failure mileage was approximately 2,000.
