Warnings problems of the 2021 Hyundai Palisade

While vacationing in myrtle beach with my family the vehicle alarmed and then progressed to critical failure of safety functions while traveling at approximately 55mph on Friday April 3, 2026. The vehicle was brought to myrtle beach Hyundai where it was eventually diagnosed and repaired as an alternator issue that I have found to be common with this specific vehicle. The issues I have experienced with this vehicle go far beyond a typical mechanical concern. Over time, the vehicle has exhibited repeated electrical system malfunctions, including: - false blind spot collision warnings when no vehicles are present - intermittent failure of the crash avoidance system - loss of cruise control functionality tied to system faults - a broader electrical failure event that triggered multiple warning systems simultaneously most concerning, these failures have occurred while the vehicle was in motion, creating an unpredictable and potentially hazardous driving condition. The loss and unreliability of critical driver-assist and safety systems directly impacts driver awareness and vehicle control, which raises serious safety concerns. Despite multiple attempts to have this diagnosed through the dealership network while under warranty, no definitive root cause was identified, and the issue has persisted. This suggests the possibility of a systemic electrical defect rather than an isolated component failure. Additionally, I have found that similar complaints involving electrical system irregularities and cascading warning system failures have been reported by other owners of this model, further supporting the concern that this may represent a known or emerging defect pattern. Given these factors, I do not believe this situation should be categorized as routine. Instead, it warrants review under the lens - vehicle safety risk - potential defect trend - failure of critical driver-assistance systems during operation this vehicle has not been inspected by the manufacturer.

The forward collision warming sign just activated when there is no danger. The car will suddenly apply sharp brakes when you are even on the high with a speed over 65 miles per hour. It is very dangerous and scary and can lead to accidents. My car false alarms get activated more than three times a day. I hope Hyundai will recall this and fix this issue.

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.

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.
