Mine is having the same issue. Going to service soon. Curious if it's a firmware issue though. Seems like there's something about the driver door in particular.
I don't have a medium size dog to try this on, but wouldn't recommend this for safety reasons anyhow. I'd be curious how well they could fit in the back seat area with the seats up.
I'm taking delivery on Sunday (AWD). What questions remain for owners that haven't been addressed by current owners (ie employees)? I'll start creating a list of things I can answer.
