Help Diagnosing Issues?
My girlfriend has a 2008 with around 120k miles on it. It's been pretty flawless but yesterday the RPMs started surging while idle and made kind of a high pitch humming noise when accelerating.
Today on her way to work she said the radio was going in and out, the battery light lit up and then the rest of the dash lights came on, and the speedometer stopped working.
Any idea what could be the problem? Could it just be the battery?

Alternator? If it still starts, it's not the battery...yet. A bad alternator can kill the battery though, and it will run dead and leave you stranded if the alternator isn't charging.

the voltage reading doesnt really tell you the health of the alternator. it could read 14.4v and not be able to charge 1pF. the alternator and battery need to be load tested separately.

Well, she just called to tell me the vehicle wouldn't start when she was on her way back to work from her lunch break so it sounds like it's the battery that just died.

But you don't know yet if the battery was always the problem (not likely as it started previously), or the alternator (my bet).

Thanks to those who offered their assistance.
It turned out to be the battery and the alternator. The battery was the original one that came with the vehicle so it's no surprise it died.

It was likely killed by the failing alternator, things like that don't fail in pairs on their own. Glad to hear you got it sorted.
