My 2011 Malibu car radio when turned on will start phasing on off after 20 minutes. Started about 2 months ago, with only 80,000 miles. My turn signals while working started doing the on off sound of the turn signal. The CD will do the same on off so it seems to be the whole system. Will replacing the radio fix the issue or is it something internal - electrical??? ---

How old is the car battery? All type of electrical issues can happen with an old battery. ---

I would suspect a faulty common power connection that supplies power to those areas
