2021 Hyundai Palisade Driver Assist & ADAS Problems

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.

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.

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.

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.
