04 Grand Prix

I want to know if anybody out there has had the problems I’m having. Charging system failure light comes on about once a week, then the ABS & traction control lights are coming on and I can feel a vibration from the pedal and a humming noise! Replaced the sensors which fixed it or so I thought. It started doing it again. What is causing this & is this a common problem?

How old is the battery?


Battery is about 2 yrs old
