2026 Hyundai Palisade driver assist problems

FORWARD COLLISION AVOIDANCE: WARNINGS

I first brought my vehicle to the Towson MD Hyundai Service Department, near my summer home, upon receiving a warning that the front sensor was not operating. I was advised that the issue will be covered under warranty. Imagine my surprise when I was advised that it would not be covered because the service team located documentation in the vehicle's file indicating that the sensor had been damaged while the new vehicle was being transported to or delivered to the Sarasota FL dealership where we purchased it. They said this documentation specifically chronicled the damage. I reported this to Hyunai's upper mgmt, was assigned a rep who promised to contact Sarasota on my behalf and work to resolve the issue between the two dealerships. After many weeks, she reported back that Sarasota denied that this damage had occurred because the notes/documentation Towson located could no longer be found in the system. But she assured me that they would continue working with the two dealerships to get to the bottom of what had occurred and she would get it covered. It took most of the summer, many calls from the assigned representative stating she was still trying to reach the various parties involved; very confusing as I have never had trouble reaching a service member or manager- and each time made me reiterate the issue, history, and assure that no collision had taken place. Ultimately I was informed Hyundai had determined the damage is not covered under warranty because of what they characterized as external damage, likely due to collision, Of course Iam stunned. The repair will cost approximately $2,000. I want to be unequivocally clear on this point: There has been no impact or visible damage to the front bumper verified by Towson to which she told me "Impact doesn't always show. I have read online about a number of these incidents. i feel Hyundai is clearly trying to cover an ongoing issue that they don't want to address. I am happy share my correspondence with you

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

Adaptive cruise control controls the speed limit based on Maps or actual signs was making an error! I was in a 60 MPH area when the system would read the route number sign and mistake it for speed limit. This happened both on state route 80, and state route 70, the car would accelerate up to that speed indicated by the route sign for a few seconds and then realize somehow it was in error and drop down to legal speed. Its a surprise for the driver.

LANE DEPARTURE: ASSIST

When using "Lane Keeping Assistance" the vehicle pulls slightly to the right and continues correcting itself creating a snake like pattern. This is unsettling and other vehicles that I own do not have this pattern including the same model from previous years. This feature is design for safety, however when "Lane Keeping Assistance" in operation the pulling to the right looks like you are going into the other lane then correct's itself and repeats not giving the feel of safety. I have taken it do the dealer and file a report to hyundai both parties had stated they cannot do anything without an error code. I have seen other customers complain about this issue with my make/model. Please help correct this issue. Thank you

LANE DEPARTURE: ASSIST

I am reporting multiple recurring safety concerns with my 2026 Hyundai Palisade. Loss of acceleration: Under heavy throttle, the engine revs to approximately 5,000 RPM but the vehicle does not accelerate as expected. This has occurred repeatedly and appears more likely after the vehicle reaches normal operating temperature. During one incident on the highway, I needed to accelerate quickly to avoid surrounding traffic, but the vehicle did not respond as expected, creating a potential safety risk. An authorized Hyundai dealership inspected the vehicle and reset the transmission adaptive values, but the condition remains. Lane Keeping Assistance: The Lane Keeping Assistance system consistently positions the vehicle toward the left side of the lane instead of properly centering it. The issue has been reported to the dealer, but the condition remains unresolved. Power second-row seat: The power second-row captain’s chair can continue moving while folding, creating a hand-crush hazard if a person’s hand is in the path of the seat. It also interferes with proper third-row seat operation. This issue has been reported to the dealer and remains unresolved. These issues have been reported to Hyundai and remain unresolved after dealer inspections. The vehicle is available for inspection, and I have documentation and video evidence of the acceleration concern.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

Stopped at the gas pump and filled up. When I went to leave all dash lights were lit up and car wouldn’t move. Brakes were locked. I tried restarting and restarting. Brakes would lock up when I tried to move, either direction. I finally gases it enough that it screeched the tires to move it from in front of the gas pump.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

It appears there is an ongoing issue with the Driver's Assistance. More specifically with automatic braking regarding forward collision. On 4 separate occasions, the vehicle has gone haywire with several alarms and icons going off at once and then sudden braking in the middle of the road before I have even realized what is going on. The issue is the car decided it was time to slam on the brakes right in the middle of the road while I was driving so it was very jarring. I have brought the vehicle to the dealership once and they kept it for 2 days to inspect the problem and could "not reproduce the problem". So they returned the vehicle to me. However, the issue occurred 3 more times after they returned it to me within 3 wks. So, I am dropping it off again for them to keep until they locate the problem now that I believe I have narrowed it down to the Driver's Assistance and forward collision issue. When I disable the driver's assistance/forward collision toggle, there "appears" to solve the issue. I have not had the same problem when that specific toggle is off as of yet. There have been no inspections from a manufacturer rep, police or insurance rep. There were a ton of warning lamps at one time just prior to the automatic braking, some regarding power train, battery, and several others. I have photos.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

2026 Hyundai Palisade Calligraphy, VIN [XXX] , purchased March 6, 2026 with under 2,200 miles at time of incident. SAFETY INCIDENT: While operating under adaptive cruise control at highway speed, the vehicle experienced sudden unintended acceleration followed by severely delayed braking response. At least three trailing vehicles were forced into emergency evasive action to avoid a multi-vehicle collision. Family members were present. This event represents a direct and immediate threat to the safety of vehicle occupants and the public. The root cause has not been definitively identified or resolved. The authorized dealership confirmed CAN-Bus resistance irregularities — 160 ohms versus the designed 120-ohm specification — governing acceleration, braking, and all driver assist systems. Prior symptoms included flickering interior lighting. An initial module replacement failed. Repair has escalated to full wiring harness replacement with no parts availability and no confirmed timeline. The safety event remains undiagnosed and unresolved. The vehicle carries three simultaneous active safety recalls — 293, 296, and 297 — all involving electrical and wiring systems on the Calligraphy trim exclusively. None have permanent remedies. The vehicle has been in dealer custody since March 21, 2026 and is available for inspection. Hyundai Motor America active case — No. XXX. This vehicle is not safe to operate.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

On at least 8 occasions, the vehicle has issued a warning to take control now of the vehicle and then begun to stop the vehicle. On 2/16/26, it tried to stop the vehicle on two occasions, and the driver had to press the gas pedal as a car was approaching from behind. I have videos and dash cam videos of several occurrences. It also has determined that an overpass was an obstacle and tried to stop the vehicle. I have taken it to the Hyundai dealership 5x. Hyundai cannot duplicate the issue, but the videos clearly show the problem. It is random. There is a significant defect with the sensors and/or software.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

Constant and consistent Alerting (Attention) with the (steering and eye alert) icons present. NOTE: It would be helpful to understand and be told the exact sensor or type of alert (eye camera, steering input, forward camera) that triggered the alert! As it stands, every few seconds to minutes the alert states driver is not attentive. Eventually between 2-8 warnings is unrecoverable and the cruise control shuts itself off after a myriad set of warnings. No matter what is attempted the car ends the cruise control and the driver MUST maintain control at that point (decelerating from highway/interstate speeds dramatically). Myself and all family drivers experience this IMMEDIATELY after activation. Dealership has reported no trouble after 50 miles of driving (as stated). I have video of this issue and am adding them to youtube (2026 hyundai palisade cruise control fail) for others to see. This is UNSAFE and DISTRACTING! The alerts alone are enough to deactivate this (if available, but: it cannot be deactivated!) let alone decelerating from speed for "no good reason" outside of drivers DIRECT control. The only solution I HAVE is to not use cruise control and the safety features (as they are marketed to work) and negate the safety features I purchased the vehicle for.

Entire instrument cluster goes black while driving. Speedometer, odometer, tachometer, turn signal indicators, everything stops working and just a blank screen. Have a video of it happening. Took it to hyundai and they would not approve tear down to find what is causing and said that it is not a safety concern, yet this would cause the vehicle to fail safety inspection in our state.

LANE DEPARTURE: BLIND SPOT DETECTION

New Hyundai Palisade Hybrid Calligraphy AWD speedometer and critical information screen and heads up display while driving goes blank. This has happened to me twice. I have been directly in contact with Hyundai USA and my local dealership to resolve this critical safety issue. Hyundai engineers have been working the issue with suggestions to my dealership to identify and resolve the problem. Hyundai engineers are shotgunning the solution with no success. With this safety issue in mind, I request that you contact Hyundai to request they have a product recall on this vehicle. This problem puts just not me but all other drivers at a significant safety risk on our highways. I request feeds back on this issue

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

Problem Statement: Instrument cluster has an instrumentation update lag of approximately 10 seconds. The problem may or not be present when you turn the vehicle on. Description of Problem: Turning on the vehicle. The Instrument cluster does not load properly. Different display elements appear in a different sequence than normal. The speedometer remains at zero even though the car is moving. The lag to begin changing the speed indicated is approximately 7-10 seconds. The car can be moving at 60 miles per hour, and the speedometer indicates zero. When the car is stopped the guage may read the prior steadystate speed of the vehicle. For example. Going from 65mph to a stop the speedometer will continue to read 65mph even though it has stopped. Potential Safety issues •Driver Speed Awareness: The driver may unknowingly exceed speed limits, exposing themselves to traffic citations or legal liability. •Inability to gauge speed accurately may lead to unsafe driving behaviors, such as entering curves or approaching intersections too quickly. •Braking and Stopping Distance Misjudgment: If the driver believes they are traveling more slowly than they actuallyare, they may underestimate stopping distances. This can result in rear-end collisions, failure to yield, or inability to stop in time for pedestrians or cross traffic. •Acceleration and Merging Risks: During highway merging or lane changes, the driver may not accelerate appropriately relative to surrounding traffic. A lagging or frozen speedometer can cause misjudgments of closing speeds, leading to sideswipe or merging collisions. •Entering a curve: Navigation-based Smart Cruise Control might expect you to slow down for a curve or exit. But if speed is misrepresented, it might delay braking or deceleration, causing the vehicle to approach the curve too fast, increasing risk of lane drift or rollover. Dealerhas been excellent to work with. They are aware of the issue and are recitifying the problem.
