^^^ You have nothing to worry about. Simply be proactive and replace the battery because that is the problem. The car starts shutting down features to conserve battery power when the battery gets near the end of its life hence your clock and radio issues. I replaced mine recently with a Duralast from PepBoys. Cost $99 bucks and is a like OEM replacement. Make sure you mount it correctly, attach the vent tube and get it registered at the dealer after you install it. The whole install took me about 15 minutes including time to remove the trunk interior cover panel and reinstall it. There is no need to pay dealer prices for this. The registration cost me $60 bucks and some people pay as much as $125, but it is required to make sure your battery is properly registered to the car's computer. Some people will try to tell you it does not have to be done, but problems can occur and the battery life can be drastically reduced by failure to get it registered.
