I lease a 2025 Hyundai Tucson SEL. This vehicle has experienced repeated electrical and safety system malfunctions. Display/infotainment failure: The center display has shut off while driving on at least 10-15 separate occasions. This has occurred while I was actively using CarPlay for navigation in an unfamiliar area, causing loss of directions while driving. Forward collision/automatic emergency braking (AEB) malfunction: The AEB system engaged unexpectedly and unpredictably while I was driving on the highway, causing the vehicle to brake suddenly. This resulted in another vehicle rear-ending me. This occurred while I was driving home from a doctor's appointment. I understand this vehicle/system was subject to a manufacturer recall related to this issue. AEB failure to engage when needed: On a separate occasion, while I was backing out of a parking spot, the emergency braking system did not engage or respond when needed, and I narrowly avoided being struck (T-boned) by another vehicle. Warning system malfunction after repair: Following the highway incident, I brought the vehicle to an authorized Hyundai dealer, who performed a front safety system software update. Approximately two days later, while driving on the highway, a dashboard warning appeared related to the front safety system. This warning disabled cruise control and other related features. Dealer inspection/dispute: I brought the vehicle back

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.

The adaptive cruise control reduces speed when the car's driver camera "senses" that driver is distracted when in fact, this occurs frequently within even a 30 minute drive: it senses "distracted driving" due to wearing sunglasses, short stature making in cab camera have difficulty seeing eyes of driver, etc. This is a frequent problem in my car and a frequent problem in driver forums. This is unsafe when it slows car without warning and is stressful. Upgrades needed for safety.

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.

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.

Concern: DAW Driver Monitoring System False alerts shuts down cruise control. Safety issue when passing on interstate and suddenly the cruise shuts off and has to be reset. This warning sometimes goes off randomly and not due to driver attentiveness. If my arm is in top of steering wheel it blocks camera and wearing certain types of sunglasses. This system is asking the driver to not put his arm on top of wheel which is ridiculous.
