“Main touch screen will not respond when it is cold outside. We were at our home in wisconsin until oct 30, 2019 and it would not respond to touch ( navigation would respond to voice only). November 4 until april 4 2020 we were in arizona ( temp in the 65-75 range)and had no problems. April 4 till present it will not work in wisconsin (temp in the 40-50f range). Also screen gets very warm almost hot to touch when it will not respond to touch. Hopping it will not start fire before it gets fixed.”

“We purchased our 2020 Hyundai Palisade limited six weeks ago. Currently has 3000 miles. The blind spot collision warning system (bscw) has a malfunction and stops working after driving a few miles on both highway and city/country roads. There are no cars or trees/obstacles around the car when it deactivates. Restarting the car resets the bscw system, but it malfunctions again in a few miles. When the system is deactivated, we cannot turn off blind spot active assist--it gives a controller error. We tried shutting off the bscw system indicator in the heads-up display. …”

“While driving on highway 290 west to fredicksburg, texas on april 2,2021, speed limit varies from 50-60 MPH, the vehicle just stopped, all systems were out, message on the screen said take to service, when convenient . It was very scary as the vehicles from behind were honking and I could not get the car to the side. It could have been a major accident with fatalities.”

“2100 miles and the digital and analog speed odometer both stopped working. The gas gauge also acted erratic. It wasn't showing the gas as full but the tank had just been completely filled (picture has example of both). Dealership unplugged the battery and reset the vehicle to factory settings and fixed the problem. I work for a car electrical component manufacturing supplier and it is believed this is caused by software within the instrument cluster because the speed odometer and the fuel gas aren't connected within the vehicle.”

“1) first issue was a cracked windshield within the first 500 miles. Driving down the highway, no foreign object, suddenly a crack started to form. 2) second issue is a blind spot warning system alert when no cars are present. 3) third issue is automatic wiper that suddenly come on when no rain or debris are present. 4) fourth issue, but far from the last, is the ongoing wind noise problem that Hyundai can’t seem to solve. It is so loud on the highway that the drone is louder than the radio. I’ve measured this as high as 86db.”
