2026 Hyundai Palisade Driver assistance Problems

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

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.

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.

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.

We lease a 2026 Palisade with only 4k miles. Several weeks ago I was going through a toll plaza, car would not accelerate after slowing down, as if it was in neutral. All of a sudden it kicked into gear and car lunged forward. 10 min later at a traffic light car failed to accelerate after a complete stop. Press the accelerator sluggish response, then kicked back into gear. Very Scary. I pulled over and notified the dealer. Then set an appoint. Dealer did a diagnostic, found no issues, could not replicate problem on test drive . Everything was fine a few weeks. My son took the car. Had the same exact issue with vehicle not accelerating. Then kicked into gear really hard and vibrating. This was scary for him because he was in a parking lot. Luckily there was no accident as a result. However, this time an error code (check engine light) came on and the Hyundai app showed a DTC CODE- P001600 (powertrain / engine). Car was immediately taken to dealer on May 28th 2026. It is now Jun 11th. Still no time frame for fix. The THINK it a software issue and Hyundai is still "working" on a solution.

While driving on my 2026 Palisade Calligraphy over last 6 months I lost all throttle/ gas response to engine on 12 separate occasions.The 3rd incident nearly resulted in serious crash in 55mph traffic. Went to dealer next day on 11/15 ref# 41788829 service found no codes, reset system and recommended a flight recorder to help diagnose. Filed with NHTSA on 12/3 after next incident ref # 11702738. Requested flight recorder multiple times with dealer and Hyundai case manager and after multiple visits, diagnostic drives and component replacement on 1/20 and 2/23 the dead throttle continued. On 4/7 I was finally issued recorder and captured 3 incidents of the problem that could not exist within 2 days. Dealer acknowledged problem and says they can not fix without help from Hyundai engineers. Hyundai will not buy back and tell me to go back to dealer for resolution. Dealer claims to have submitted all relevant info to Hyundai but will not produce requested paperwork to me for most of visits (illegal? ). I have been assigned 3 separate case managers who try to assign new case #42539227 and separate it from initial ref # 41788829 while denying buyback with documentation they refuse to share. I am driving an unsafe and dangerous suv with 3 clearly documented Hyundai flight recorder incidents and acknowledged safety issue.

Incident

Nov 15, 2025

While traveling along a high-speed highway, our 2026 Palisade unexpectedly suffered a severe loss of acceleration. Despite fully depressing the accelerator pedal, the vehicle struggled to exceed approximately 20 miles per hour. This alarming malfunction placed us in a precarious and potentially dangerous situation, as the drastic reduction in speed exposed us to the risk of being rear-ended by faster-moving traffic. On a separate occasion, the vehicle again exhibited troubling behavior, failing to respond appropriately while merging onto the highway. This hesitation significantly compromised our ability to safely enter the flow of traffic and could have easily resulted in a collision. Disturbingly, in both incidents, the vehicle provided no warning indicators or alerts on the dashboard, leaving us without any guidance or explanation for these critical failures.

I picked up my vehicle from the dealership after it being there for almost 2 weeks for multiple DTC codes, a dash cam component replacement, and recall updates. On the way home, my check engine light flashed on and off multiple times while driving at highway speeds (although no codes were recorded in my Hyundai app diagnostics). When I exited the highway, I came to a stop sign on the off ramp and waited till cross traffic cleared. I went to accelerate into traffic, but my car would barely move. This happened 4 more times in the short drive to my home. This could pose a serious safety risk if I'm unable to accelerate to merge into traffic and get stuck in cross traffic.

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.

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.

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.

While driving, the vehicle displays a warning of "Eyes on Road, Hands on Wheel". It has happened 6x since vehicle purchase, most recent on 10 Jan 26. The most recent occurrence was 10 Jan 26. Hyundai has issued a bulletin that this could occur when wearing sunglasses. The most recent time it was raining, no sun, no sunglasses and hands were on wheel at 10/2. Warning message displayed for several seconds (eyes on road/hands on wheel) and then went into stop mode on the highway. Tapping the brakes broke the lock and are continued without stopping. Been to dealership 3x. Hyundai says it can be caused due to sunglasses. Most recent time, no sunglasses.

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.

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

I am a 77 year old senior and was driving my 2025 Hyundai Tucson Highbrid at approx. 70 MPH on the highway, then suddenly there was significant shuddering through the Tucson with noticeable loss of power. The Tucson dropped to 30 MPH. After that it would accelerate with significant shuddering. This would repeat several times while driving. In addition there were no Malfunctioning indicators, or warning lights. We were never so scared in our lives. This occurred on Thursday , October 2 nd.2025 at around 1:00 P. M. On highway 355 and 53 traveling Northbound.

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.
