Owner reports
Selected complaints filed with NHTSA by 2023 Hyundai Palisade owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2023 Hyundai Palisade. The contact stated while driving at approximately 4 MPH as he was turning onto a main road, the vehicle slid on a patch of ice and slid across the roadway. The contact stated he had crashed into the curb on the opposite side of the road with his front passenger side tire and came to a stop. The contact stated that there was no damage, however, the steering wheel was off-center at 45 degree to the left. The contact stated that he could steer the vehicle in a straight line, but the steering wheel was at a 45-degree angle, as if he was turning to the left. The contact stated that after the crash numerous warning lights were illuminated. …
While sitting at a stop sign, I attempted to place my vehicle in Park. I opened the driver's side door, but the car had not actually shifted into Park. None of the vehicle's safety systems engaged when the door was opened. The car rolled forward with me partially outside the vehicle, dragging me until it struck a tree. This incident reflects a critical failure in the vehicle's electrical/safety systems: The transmission did not engage Park when selected. The door-open rollaway prevention system did not activate. The automatic front collision system failed to stop the vehicle. Because multiple electronic safeguards failed at the same time, this appears to be an electrical or computer system malfunction rather than driver error.
A severe safety concern with our 2023 Hyundai Palisade, which has been present since the day we received the vehicle. When braking on uneven roads, the brakes jitter and stutter. This issue does not seem to occur on flat surfaces; however, it is always at lower rate of speed when roads have bumps. On three separate occasions, I have experienced a complete loss of brakes, and my wife has faced the same issue at least five times. When this happens, standing on the brakes does not trigger any response-there are no warning alarms, and the brake system completely fails. The potential to hit another vehicle or pedestrian, or veer into oncoming traffic, is very high, and in fact, I've had to swerve into a curb (causing curb rash to the right passenger rim) to avoid a collision. Due to the severity of this problem, I no longer allow my wife to drive the vehicle. …
Recently, the emergency braking system has been activated without warning on multiple occasions, including while driving on the freeway and local streets, even when no obstacles were present. This unexpected braking could potentially lead to dangerous situations, especially at high speeds. The emergency braking system unexpectedly activates without any obstruction, indicating a possible malfunction with the front sensor or ABS system. The vehicle is available for inspection upon request. The unexpected activation of the emergency braking system, especially at high speeds on highways, poses a significant risk of rear-end collisions, sudden deceleration, and potential accidents involving other vehicles. The issue has been observed but not definitively confirmed or resolved by the Hyundai dealership, which suggested recalibration of the front sensor without assurance of a solution. …
System that malfunctioned was the braking system Safety was risked because vehicle doesn't stop as it should at low speed below 30mph. Safety of occupants as well pedestrians and other motorists affected. Problem can be reproduced although dealer refused to confirm. I am in the process of getting it confirmed independently. Vehicle and components not inspected by manufacturer, police nor insurance. Although I am in the process of putting an insurance claim in. The issue has been reported and confirmed by several other owners of same make and model and year. No prior warning of issue to it happening. The problem: At low speed below 30mph and braking simultaneously when going over rough ground (non slippery), potholes or in my accident going over a 6" drain to my garage, the ABS kicks in when it shouldn't and the brake pedal vibrates and the vehicle lurches a bit. …
I was slowing down approaching an intersection with cars already at a full stop up ahead. I was braking to slow down in preparation to stop. As I got closer, I drove over railroad tracks and felt the brake pedal begin to vibrate like the automatic emergency braking system kicked in. With my foot still on the brake, the car continued forward without any additional decrease in speed. I pushed my foot down as hard as I could and the car stopped inches from the car in front of me. I'm not sure if me pressing on the brake more even did anything or if some other collision avoidance system in the car stopped it before colliding with the car in front of me. There was beeping and the display switched to show cameras in front of the car, which happens when getting close to something while parking, etc. Luckily I was slowing and not at a high rate of speed. …
On 7/26/2024 vehicle in to dealer because warning light coming on if doing 55-65 mph stating front radar blocked, front safety system disabled. Vehicle at that time had 15,488 miles on it. Told dealer warning light does NOT come on while local driving to stores, for gas etc. Dealer said radar module had damage due to "minor collision". Not so, I am [redacted] uses car for local trips mostly. Contacted service manager at dealer--- Conicelli in Conshohocken PA pursuant to procedure to be followed in Warranty booklet, no relief. He tried to push me to make a claim with my auto carrier which I did not. This is a warranty claim not a collision claim. I then contacted Hyundai direct & they also tried to steer me to a auto collision claim. I declined & filed a claim for ADR with the BBB & it is pending. Going on line I see this appears to be a common complaint with the Hyundai radar module.
I was approaching a stop sign, slowing down to around ~20 mph, then gently applied the brakes. All of a sudden, the car stared to lurch forward and the steering wheel shuddered violently as the ABS braking appeared to kick in. As the brakes were applied, the vehicle kept bouncing forward in spurts rather than stopping and it took almost twice as long to stop than it should have. There was a vehicle in front of me and my vehicle was a foot from rear-ending that car despite me slowing in advance and attempting to brake gently. The collision warning system kicked in and I suspect that the vehicle stopped itself, even though I was firmly holding the brake pedal down. My wife experienced te identical situation a week later, so this is becoming very concerning. …
My sensors have been having issues since the day I bought my car march 5 2023. It would be intermittent, and became constant. The error reads, "check parking distance warning system" as well as "ultrasonic sensor error or blockage" and my sensors are clean. Nothing blocking them whatsoever. It's constant. I went to my dealership for them to say someone may have hit my car while I was I. The grocery store. Shouldn't there be some serious damage? I don't lcoe the lying. And I don't love how they tried to get me to pay because me sensors wouldn't even calibrate. They said anything could knock them out of wack because hyundai sensors are super sensitive. Well then they need tk be less sensitive. My car is garage kept, barley leaves the house currently has only 2000 miles after having the car for 2 months now.
On four separate occasions, the forward collision assist turned on when a car in front of my car has moved over into a turning lane and they slow down. The car aggressively brakes, and on two occasions has come to a complete stop in the middle of the road, not allowing me to move the car until the warning goes away. I was nearly rear ended on two occasions because of the cars sudden aggressive braking. I called the Dealer service number department and they told me they wouldn't be able to diagnose the issue without trying to reproduce the issue which neither they nor I felt comfortable with. With the exception of the warning coming on during the event, there are no other warnings visible and the car returns to normal once it figures out there was no collision.
