Adaptive Cruise Control problems of the 2025 Hyundai Palisade

While driving on the highway using the adaptive cruise control feature in my 2025 Hyundai Palisade, the vehicle suddenly and aggressively braked for no reason — even though there was no vehicle or obstruction ahead. This happened in normal highway traffic and caused vehicles behind me to brake suddenly, putting me at extreme risk of a rear-end collision. It was a very dangerous and terrifying experience that made me unable to use the cruise control feature since. For a brand-new vehicle with advanced safety features, this type of malfunction is completely unacceptable. Hyundai has not provided a proper explanation or resolution. This poses a serious ongoing safety risk to myself and others on the road and must be investigated.

Randomly, the second row seat belts will unbuckle by themselves, and the seat belt warning will randomly go off indicating the seat belt was unbuckled all the while no one was sitting in the seat. At random, while using the adaptive cruise control, the car will brake by itself, when there is no car close enough in front to activate the braking system. A few times, while using the adaptive cruise control, the system speed up for no reason. The only way to get the car to stop speeding up was to disengage the cruise control. Braking did not help.

Hyundai "Smart cruise control (scc)" I had my scc set at 54mph. I entered a broad curve, which was gentle enough that it was safe to maintain that speed. Ahead was a left-turn turnout lane for vehicles wanting to make a left turn off the highway. This turn lane is part of the broad curve, too. A vehicle was stopped ahead in this appropriate turn-off lane waiting for oncoming traffic to clear. As my vehicle entered the curve, the radar/camera at the front of my car detected this stopped vehicle a little ahead of me, and immediately began to brake my car into a panic stop. I was thrown forward a little in the seat, and the vehicle immediately behind me had to suddenly brake, too, in order to avoid read-ending me. These was no need for this of course. With conventional cruise control, I would have been able to navigate through the curve at the set speed, and all vehicles in the vicinity, including mine and the vehicle behind me, would have been safe. The Hyundai owner's manual points out that the scc may well malfunction in curve situations (among many, many other situations). Smart cruise control is an accident waiting to happen. Please, please get this feature off of vehicles sold in the united states. Return control of the vehicle to the drive, not some camera. Thank you.

Today, March 27, 2026, I sent an email to Hyundai customer affairs that stated the following: "to whom it may concern, on January 21, 2025, I emailed Hyundai customer affairs about an issue that is of significant importance. To date, the only response I have received regarding this issue (case # xxx) on February 2, 2025, acknowledging my email and assigning the reference case number. However, the issue with the cruise control's resume execution is unacceptable and [likely] dangerous. There is no reason for the cruise control to accelerate in such an aggressive manner. What is it going to require for this issue to resolve/address this?" while the car has traction control, there is no reason for such an aggressive manner for the cruise control to accelerate as you can see in my email it to Hyundai their lack of action is concerning.
