My radio stations clear every time i turn my car off.
This is either #1 a case of operator error or #2 a failure in the radio.
To solve #1 I suggest you open up your owners manual and read what it takes to permanently store your stations. If this really IS a 2019 car and my first suggestion does not work, then the reason is #2. Take it to the dealer and tell them this problem and they will fix it for free.
