2025 Hyundai Palisade: adaptive cruise control problems

Filed Sep 28, 2026 · Driver assistance · OH

On August 10, 2026, at approximately 12,302 miles, I took the vehicle to an authorized Hyundai dealer after it stalled multiple times, including once while accelerating. I also reported sluggishness/loss of power. The dealer was unable to duplicate the problem. The vehicle subsequently stalled two additional times. In September 2026, while driving at highway speed with cruise control engaged, the vehicle suddenly and aggressively decelerated/braked as though it detected an obstacle ahead, although no vehicle or obstacle was present. A similar event occurred the following day. Unexpected braking, loss of power, or stalling at highway speed creates a serious collision risk. I have also experienced a forward-collision warning when no vehicle was in front of me and intermittent jerking/hesitation. I returned the vehicle to the Hyundai dealer on September 22, 2026, at approximately 14,548 miles. The dealer performed diagnostic scans and approximately 42 miles of road testing. No relevant DTCs were found, the problems could not be reproduced, and no repair was performed. The dealer documented the result as No Trouble Found. There were no consistent warning lamps or messages before the stalling or unexpected deceleration. The cause remains unresolved despite multiple dealer visits.

This 2025 Hyundai Palisade Calligraphy is a “Top of the Line” model loaded with automatic gadgetry that is NOT ready for Prime Time or any roadway. It is unsafe for the following reasons: Problems appear to be software up-date related; the software updates way too often via overnight web connection. These updates not only change existing status of mundane systems (hatch or doors unlocking opening, etc.); these updates appear to insert bugs into the operating system which then affects the safety of automated vehicle systems which then create unsafe driving conditions on roads. The biggest safety concern is with Hyundai’s “Smart Cruise Control” system. When a driver chooses a set speed they want to follow, here is what happens often: The Hyundai Smart Cruise Control is turned on and a driver “attempts” to index to the desired speed. Once this speed is actually attained all is good. IF the posted road speed limit increases from 25 MPH to 40 MPH the driver has 2 choices, hold the speed increase button in for 3 seconds for a 5 MPH bump up OR press the button quickly for 1 MPH bump ups. Instead, here is what happens OFTEN, a 3 second hold jumps the speed to 65 MPH desired speed! Or, a quick bump jumps to 50 MPH desired speed! It is random and sporadic to what actually happens, so a driver must pay attention and cancel cruise control quickly, then get things back to normal and begin over. All this occurs while moving on a roadway at speed, hence UNSAFE biggly! Also, what happens, these vehicles front view camera read the posted speed limit (on a street-side sign) and “automatically” sets the posted speed into the Hyundai “Smart Cruise Control”. It has upped this SUV’s speed to 95 MPH and 75 MPH automatically! The driver needs to be attentive to what the automated “Smart Cruise Control” systems are actually doing; all while driving on busy roadways! This is VERY UNSAFE! I believe web software updates are creating these problems - STOP updates immediately.

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.

. What component or system failed or malfunctioned, and is it available for inspection upon request? ---------- Nothing failed but the lane assist feature forces the car to drive hugging the left lane and not on the center of the road. This can be very dangerous on a freeway when passing big wide trucks. If you use the cruise control this feature automatically turns itself on. . How was your safety or the safety of others put at risk? ------ When the lane assist is turned on the car drives close to the left line and not on the center of the road and this could be very dangerous when passing large wide vehicles or those with wide trailers. Has the problem been reproduced or confirmed by a dealer or independent service center? ------------ Yes. I took it to the dealer and they said that's how the car was designed and there is nothing they can do. They asked me to contact the Hyundai Customer Affairs. I opened a case number with Hyundai Customer Affairs. They said that if the dealer did not find a problem then there is nothing they can do. I am stuck with the problem. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? ------------------- See above. When I googled to see if other people are complaining about the issue, I found out that there are other people complaining but no formal complaint has been put forward.

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

When using lane assist the vehicle is pulled into other lanes, including into oncoming traffic. This happens even when the vehicle is centered in the lane. This is extremely dangerous because it can cause an accident. When using cruise control, the lane assist comes on automatically which is extremely dangerous because the vehicle is going at high speeds on the highway. The dealership is aware of the situation. Both the mechanic and the salesman have driven the vehicle with me and experienced the problem. Additionally, the salesman and I drove another 2025 palisade and the lane assist problem was present in that vehicle also.

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.

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.
