Ever since we got our first real snow fall and temp. fall here in Iowa, my Monte has been having this problem. I'll get in my car, turn it to the ON position...when I do this, my Battery Guage will go from half way and drop to just above the red. Also, the battery light comes on in the message center. However, She will still start everytime, only occasionally it will hesitate slightly. The battery is 1 year old as of this winter. Also, my car sits in an insulated garage every night, so I don't know if it has anything to do with the temp. or if that battery just needs a good charge? My old battery charger got left at the old house when I moved so I haven't been able to test that theory Any theories?

 

have the battery tested to start.

 

X2 Have the battery tested... We had some at work with a bad cell after six months..

 

Check connections for corrosion as well.

 

Do you have a way to monitor the voltage (accurately) while the car is running?

I wonder if the alternator isn't as high as it should be.

 

Ive been havin this same problem. I sometines get the battery light when I'm driving. It could be becayse I ha e the heat, both seat warmers and rear defogger on at the sane tine but idk. I got the battery when I got the car. So I think this weekend imma ha e it checked and charged. I was starting to look at the altenator because that looks old

 

I'll have it tested this weekend, hopefully if its bad i'm under warranty!

 

My monte has done that for... As long as I can remember I guess..
