Battery Drain

[em6788]

I just bought my 2008 Sierra in December

and it only has 5500 miles on it.

the other night i was driving and it was getting kinda cold so i started to raise my windows up

 

so i reached over and pulled the button

 

when ever i roll my windows up i always release the button then pull on it again to make sure the windows are all the way up

it was already doark outside so i could see my head lights

well when i pulled to make sure they were closed i notice the my headlights dimmed

noticeably

 

dont you think its kinda early for this be happening i know this happens when your battery is dieing

 

 

is there anything wrong or iit just me

Don't sweat it, it's fine. The new trucks have an "on-demand" electronically controlled alternator (supposedly saves fuel). So headlight dimming on occasion will be noticed, it's normal.
