I have been having trouble with the battery life of my 2008 GMC Canyon.

About 2 months ago I needed to charge and jump the Canyon after it sat for 2 weeks without starting. Just shortly after that I needed to jump it again after sitting for 3 days without starting.

I have been told that the drain on the battery was coming off of the Body Control Module, I have since had the body control module replaced (under warranty). Just a short while ago the battery drained again (it was also -40 for a period of 16 hours), I have taken the truck in again, and the mechanics told me that it could be the body control module again. Is there anything else that can be draining the battery life?

I also have a remote start on the truck, and was wondering if that can drain the battery life from the truck?

A remote start could drain the battery, but there is also a recall for reprograming the radio. On certain 2008 model year Chevrolet Colorado and TrailBlazer; and GMC Canyon and Envoy vehicles equipped with an AM/FM Stereo with CD/MP3 Player (RPO US8), the radio may drain the vehicle's battery. When a customer ejects a CD that is in the CD player and then pushes the CD back in within 25 seconds, the CD player does not recognize that the CD has been manually reinserted. When this happens, the radio/CD unit will continue to draw battery power after the ignition is turned off. This condition can be created at anytime (vehicle on or off), and will remain until the CD is ejected or battery power is lost.
Has this recall been done yet?Start there first. Then disconnect the remote start, these cause way to much trouble. Then see if you still have a drain.
