Hi im new to this sight just picked up a 06 MCSS a little over a month ago and im already having a few problems. For one when i go to drive to work in the morning when i use the auto start it tries to start and then just dies. I then start it normally and it cranks slow and then turns over starts. Also everyone once and a while the service brake assist light goes on. just curious if anybody has any input to what it could be.

 

Your battery is toast!!!

Join the line....

 

time for an optima

have fun removing the stocker,lol

 

The symptoms are not those of a failed battery. I would look at cleaning the battery terminals and making sure that they and the various grounds are tight. I would then look at the output of the alternator.

 

Haha i know i did. with out the right tools too...

 

yes they are... that's EXACTLY how mine acted when my original battery went out on me...

acted like that for a few days... then after that, nuthin'!! had to jump start it... once jump started it would stay running... but when I shut if off, 1-2 minutes later it was dead and had to be jumped again...

those are the symptoms of bad cells in the battery...

and yeah, getting the battery out is a friggin' PITA!!!!

 

ya it was the battery i just got the car back from the dealer

 

I just had mine replaced with an Exide from a vendor we deal with...$70. My Delco at 56K was not long for the world... I had to turn the battery on end and have my buddy hold the electrical center.
