| Vehicle Speed Control problems |
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.
The contact owns a 2026 Hyundai Palisade. The contact stated that while inside a residential parking lot and attempting to park, the vehicle unintendedly accelerated independently while in the drive gear position and crashed into a parked vehicle, where it came to a stop. The contact stated that no air bags deployed in the vehicle. No warning light illuminated. The contact stated no injuries were sustained. No medical attention was required. The contact mentioned she spoke with the insurance company, where it was pending inspection and repairs. A police report was not filed. The manufacturer was not notified of the failure. The approximate failure mileage was 6,100.
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.
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.
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.
