Recently my G has been acting up. At random the radio resets itself (off / on) And also at random in no specific order it resets itself and resets all of the settings as well...

I have an 03G automatic with factory stereo...

Also not sure if its related, but about a month ago My VDC Off, Brake, and Slip lights all would light up until I turned the car off. Added some Brake Fluid and I think that resolved it..

Another note, my passenger low beam keeps dying out after being installed...

 

you don't have a loose battery connection do you?

all of those at the same time is very strange..

the radio losing settings is usually an indication that the constant (memory) 12v wire going to the head has lost power.

 

Old batteries do really, really weird things in these cars, so I wouldn't discount that, but the radios in these cars are well-documented crap that go out at random.

Get the battery checked somewhere that does it for free, and if that doesn't fix the problem, it's a good excuse to kick the POS factory radio to the curb. Aftermarket FTW.
