Oct 25, 2009 - The Service Battery Charging System message keeps comming on in ... on the Information Center has started to pop up more frequently now.

needs service (e) in 1800 miles.

This year model requires a diagnostic scantool to retrieve trouble codes from the computer, most autoparts stores in the US can help you get these codes for free, try autozone, pep boys, O reilly etc.The trac control light will turn on whenever the service soon light comes on by default, the system is disabled until the light is fixed.

i sugest you find a second oppion

your fuse in radio went bad replace.

you are required to take your vehicule for a scheduled maintenance. basically just a reminder from your friendly dealer to bring your money to them

the 1st thing to do is find out which of the over 125 trouble codes is stored in the computers memory, go to any Kragen or Autozone they will test the system for free.

New oil and filter or screen filter
