Issue with infotainment system

I bought my car on 27-Aug-2019 and driven about 500Km and could not found any complain in car performance. I have an major issue with infotainment system since the day one and Kia work shop is not able to provide the resolution for the same since more than a week. Issue Description - My infotainment system is getting powered off after some time frequently and no any button on panel is working. To turn it on i need to turned off ignition of car and start it again. I have complained the same to kia workshop on 31-Aug-2019 and they called me thrice at their work shop and could not able to fix it. It is very inconvenient while travelling on road and my infotainment gets switched off and i need stop my car on side and restart it again. Because of above issue my reverse camera display got switched off in between while parking and my cars bumper got scratches.
