Sounds like it's in limp mode . Is the check engine light on , or a yellow wrench symbol ? could be a problem with electronic throttle control . Have a scan tool hooked up an checked for DTC'S - diagnostic trouble codes . Your gas pedal has sensors inside that wear out , also throttle position sensors inside the throttle body ,this sensors are inputs to the PCM - engine computer .

congratulations

Fuse is probably blown. You can replace the fuse but the underlying problem may be an electrical short that you need to find.

Drain plug or not you need to remove the pan to
clean it
You don't need to do the filter on a 2011 just yet

Umm..CD player has malfunctioned, you have warranty?
