just got a Service charging system notification and my voltage gauge is bouncing between about 13 to 15 volts. Has anyone had a similar issue or know what the problem could be? Faulty wiring, alternator, battery? Any ideas?

Hello,

This could be a problem with your voltage regulator. I have included some information for your vehicle specifically about the generator in the diagrams below, but first can please go the link down below.

You can always take your alternator/generator to your local parts house and they will bench test it for free as well. Let us know what you find out.

Thanks,
Alex
