I have a 2007 Honda Accord Hybrid that when parked for 2 weeks, the battery is completely dead. The dealer said I need to drive it every week so that is the problem. Has anyone else ever had this occur. Any thoughts? Thanks

 

I've parked cars for 2 weeks (& occasionally longer) without killing the battery. But I haven't owned a hybrid. I wonder if that's really so different? Look for some small electrical load that doesn't turn off like it should. Like maybe the glovebox light?

Bigger electrical loads (radio, trunk light) would drain the battery faster than 2 weeks.

 

If you have a DMM, you can check the battery for parasitic draw.

That's what I'd do.
