So, after the car sits for a couple of days, it sort of jerks at it's first movement, then drives normal. And if driven every day, nothing.
I think the longer it sits the more it jerks off the mark, first thing.
Seems something is slightly binding? rear end {brakes?}
With thanks for any suggestions, DST.

 

Mine does this too if I leave it for a week or two. It is just the park brake pads sticking, no big deal. If you want to get around it hold the park brake switch in release when you turn off the key and the park brake won't apply. This is obviously not a good idea if you park on a slope...
