Self leveling struts continually are trash. They do not last more than 2 to 3 thousand miles of highway driving before they are no longer safe. The adaptive cruise control randomly reads as "radar blocked". And will work only intermittently.
2021 Hyundai Palisade driver assistance complaints
Page 2 of 2: complaints 11 to 26 of 26, newest first, as owners wrote them.
On expressway traveling through Atlanta, changing lanes with plenty of clearence using signal at approximately 55 mph when suddenly alarm sounded and breaking system engaged bringing car to almost complete STOP. COULD NOT ACCELERATE and fortunately made it to berm area without causing SERIOUS accident. Turned engine off and restarted vehicle and continued on my way. Had vehicle checked at dealership and they said “all checked out and we found no diagnostics problem”. Also weren’t able to duplicate incident. I hope to God I AM UNABLE to duplicate the incident and cause fatalities including myself.
Update to complaint #11631235 At time of original complaint submission, I was unable to figure out how to share the video documentation of the vehicle speedomoter defect. Having since figured it out, I want to share this evidence with the federal safety agency
While driving on the interstate on a clear sunny day at approximately 70 mph within the span of five minutes my vehicle’s emergency braking system engaged (with visible warning on dash screen) causing breaking with a steering deviation forced to the right. There was no one immediately in the lanes next to me, and the car in front of me was 4-5 car lengths ahead, at least.
The warning sign about FCA, LDW etc. came on while driving. Cleaned all sensors and still the warning keeps coming up.
The Forward Collision Avoidance Assist (FCA) System disabled Radar Blocked pops up on the screen often. I have 2 cracks on my windshield, and I do not have the funds to replace it.
I was driving in the highway in fairly heavy rain. My lane departure system went offline first. Next my forward collision went offline. Shortly after that my check engine light came on and the vehicle started shaking. I stopped under a bridge and waited for the rain to slow. I turned the car off and on, but the issues remained. I was forced to drive 10 miles, at 30 mph, on the highway, with hazards on, to a hotel. This caused an unnecessary unsafe situation. The next day, I took to the dealer. The car ran fine. They reset the codes and said it was likely water getting into the cylinders causing 4 and 6 to fail. I really dont feel a car should do this from driving in the rain. This also caused me an unnecessary hotel stay.
Hyundai claims that this is a "Start-Up" safety feature (meaning that it is designed to re-activate itself every time you start the car, even if you had deactivated the feature), and that there is nothing that they can do about overriding this since it is a manufacturing issue. While I appreciate the notion of Hyundai trying to promote safety, I continue to be very upset by this because the system is way too sensitive and has already on 2 separate occasions, caused the brakes to virtually lock-up involuntarily at freeway speeds on the freeways, even though I was otherwise completely in control of the vehicle and certainly not on the brink of any type of accident prior. I continue to contend that this feature is dangerous and that it certainly could cause an accident. Hyundai should not force their customers to use this dangerous feature in the interest of promoting safety, when it reality, it actually does just the opposite.
Environment: Passing a single car on a two lane deserted highway. Daytime, sunny, no rain. Issue: The vehicle's emergency braking system activated (brakes were automatically activated along with the emergency braking cue in the instrument cluster) when the vehicle was returning into the right lane, almost causing a collision between the two vehicles at 85 mph. This occurred a second time 15 minutes later under the same conditions. The car was taken to the dealership for inspection and repair. The dealership test drove the vehicle and could not replicate the issue. Hyundai Engineering noted that since they were not able to replicate the issue and there were no active codes there is nothing wrong with the vehicle. If the radar is functioning properly, there must be an issue with the software of the vehicle.
This vehicle AWD system failed, the assitance systems failed, namely: Adaptive cruise, regular cruise, blind spot warning, emergency brake assist, lane keep assist, and parking collision warning.
From driver: "While traveling westbound on John Lynch St, I approached the left turn lane heading southbound on Valley St. I engaged the brakes and began navigating the left turn at approx. 30 MPH. While turning, the vehicle's "Lane Assist" engaged preventing me from completing the turn. Halfway into the turn, the vehicle continued westbound, hopped the curb, and collided with a stationary road sign that was not in use. I continued through the intersection and pulled off the roadway." Follow-on questions: 1) How fast was the customer traveling when they were actively turning? A. 30 MPH, which I am assuming was the approach speed. To the best of the vehicle operator's recollection, the approach speed was appropriately 40-45 MPH, with an active turn speed of 30 MPH. 2) What was the recent usage of the vehicle before the incident? Was it used that day? How long had the vehicle been driving before the incident? A. The vehicle was driven, by the same driver, approximately 12 miles to work the morning of the accident. Prior to the accident, the vehicle was driven around the same city as the accident for approximately two hours. 3) Did any vehicle operator notice anything wrong or unusual about the vehicle prior to the incident? A. Vehicle operator observed that the Lane Assist Dash Board Icon was blinking on and off throughout the course of a few hours prior to the accident. Vehicle operator attempted to disable the Lane Assist feature by both pressing and holding the Lane Assist Button located inside of the vehicle. 4) Any after-market equipment installed? A. Vehicle was equipped with both Law Enforcement Lights and Law Enforcement Siren. 5) Any upfits? A. The vehicle did not have up-fits. 6) Will the customer agency consent to the OEM (or the federal safety agency) retrieving information from the vehicle's Event Data Recorder? A. Yes.
The contact's friend owns a 2021 Hyundai Palisade. The contact stated that while driving 70 MPH, the emergency automatic braking inadvertently engaged. The emergency braking system warning light was illuminated. The driver had to manually release the parking brake. Additionally, while driving a stone struck the front windshield causing a crack. The vehicle was taken to the local dealer and the contact was informed that the vehicle was working as designed. The contact was also informed that the windshield was on backorder. The vehicle was not repaired. The manufacture was notified of the failure however, no further assistance was provided. The approximate failure mileage was 10,000.
Windshield cracks with the slightest impact. After 2 replacement windshields and camera calibration performed four times, the vehicle still strays into oncoming traffic lane and over the fog line with lane keep assist and lane following assist activated. camera has been calibrated three times at Safelite and one time at Hyundai dealer. The LKA & LFA systems were PRECISE IN THEIR OPERATION WHEN I PURCHASED THE VEHICLE. Now the vehicle self steers into oncoming traffic with no warning until the vehicle is over the center line. Scary as hell. Apparently Hyundai has defective and weak windshields across the board according to many internet sources. Also, apparently the recalibration procedure is not working, causing a major safety issue in these vehicles.
While driving on april 18/2021, my 7-month-old less than 2000 miles hyundai palisade started to give me alerts that some safetyfeatureswere shutting down. With messages like this "check forward collision-avoidance assist system", the same happened with the lane departure system and other safety features.since then the car has continued giving system errors after the car has been driving for a few minutes.I have already an appointmentwith the dealer's service department on 4/30.
The car was keeping the car centered in lane. There was a very slight curve to the lane. The car did not respond quickly. When the car was violating the opposite edge of the lane it over corrected to get centered. Then it violated the other edge and over corrected even more. The car was oscillating out of lane on both sides before I could regain control.
I was travelling at 50mph under cruise control with lane following and lane keeping. A car drove past me in the lane to my left at about 65mph. The computer quickly turned my wheels and sent me into the lane at my right. It was a turning lane and unoccupied. The angle of the car to the turning lane was steep. I regained control of the car before it could go off the highway to the left.
