Hi,

It shouldn't go low that fast. So, you likely do have a draw. It can be many different things causing this to happen. Oftentimes, it is a small light in the trunk, glove box, under the hood, or another place that is staying on.

Take a look through this link and let me know if it helps. Also, if you are unable to find anything that is staying on, the last paragraph in the link explains how to locate the draw using a voltmeter or a multimeter.

Let me know if that helps or if you have questions.

Take care,

Joe
