What component or system failed or malfunctioned, and is it available for inspection upon request? the infotainment system continuously changes screens without being touched. No matter what screen is displayed, it will change on it's own to various other screens. How was your safety or the safety of others put at risk? while I was driving I was using my gps via carplay and the directions were displayed on the infotainment screen. The screen started changing to other screens and at one point changed to the back up camera. I was almost in an accident because I was unable to see the directions and frightened and confused when the back up camera appeared while I was going forward on the highway. Has the problem been reproduced or confirmed by a dealer or independent service center? yes, I took the car to the dealership while it was still under warranty and they told me it was due to me using carplay and that my iphone just needed to be updated. I updated my phone and the problem never went away. So now I've stopped using carplay and the problem is still occurring. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? only the dealership. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? no warnings. The problem first appeared in late 2020 early 2021. I have a video recording of the issue as well. Also when I google the issue lots of other owners are complaining of the same issue.
