I just got back from training after only 4 days and car battery is dead. I'm about to be leaving again for a week, does anyone know what may have caused it? I will like to make sure once I jump it when I get back it doesn't happen again.

Thanks in advance.

 

Probably a bad HFL. If you happen to still be under warranty, get it in to a dealer before your warranty expires. In the mean time, pull fuse #6 or disconnect the HFL connector up in the overhead console. Do a search, plenty of threads on this isssue and "parasitic drain".

If that's the original OEM battery could also be just a bad battery. You should have it tested. Could also just be corroded/loose battery connections. Again, do a search, tons of threads on "my car won't start".

 

Ok thank you, will get tested and disconnect the HFL. Sorry on my phone and was in my friend's car so wanted to post and try to get an answer before I get home.

Of course warrenty ended 2k miles ago.

 

If it turns out to be the HFL, push very hard for goodwill. Don't give up easily. This is a well documented issue on 3G TLs.
