I figured that wonderful feature out, when we returned from a week vacation, just before I discovered the generic light duty jumper cables weren't enough to jump start the car. she now has a set of cables identical to what i carry in my diesel pickup for starting farm equipment (20ft 2gauge)
the car was driven on 6-30 mile trips in the 4 days before it was parked (Friday night 30miles, Saturday morning 30miles, Saturday night 30miles, Sunday morning, Sunday evening, Monday morning)
I jump started the car today and drove it to the dealership (25 miles) and it was slow cranking to restart when i arrived. hoping they find something, an electrical issue this early in the cars life doesn't make the future very exciting. i hope to avoid the battery tender, just because it would be a pain. heck, if I'm going to plug it in every night it might as well be a Chevy volt or something.
