Radio/tape Cd Player problems of the 2011 Toyota Corolla

The first thing I noticed was at least two weeks ago when I couldn't adjust the radio volume while driving, thought maybe there was a safety feature that wouldn't allow you to do so if driving. Today we hopped in the car to do a quick errand and noticed the radio had no display on it. While friend was in the store tried turning the radio off and back on again, then tried turning the car off and back on again finally tried pushing every button that was related to the radio. The first button would turn the radio off the next would turn it back on and so on and so forth and that is all they would do. Came home and researched this to be a chronic problem with late model Corollas. The frightening thing isn't that it isn't fixable but rather that it reoccurs within about 2 years time from the first time and mine is 6 years old and I have had it 1 month. It also sounds like more electrical systems seem to get involved the older the car is. I don't know if I can afford to buy another used car so soon on what I make. I hope someone looks into this so these cars aren't flooding the resale market. The vehicle was both stationary and moving and it was at night so the lights were on. I live in mn and the temperature was about 38 degrees.
