Ditto...if you're looking at your OBC's RANGE figure...take another look when the engine reaches normal operating temps and see if the "range" has now increased to approximately where it was when you shut the engine down last.

The OBC is taking current calculations...and a "cold" engine is consuming more fuel than when it reaches normal operating temps. So yes, when you start the car in the morning, the OBC RANGE may show a drop in distance....but it should increase as the engine warms up.

Report back if this is true (the range increased as the engine warmed up) so that we know that it was only new ownership jitters...and not another issue.

OBC Range Calculation info from owners manual
