A couple of weeks ago I had a rental that did this and it was really annoying. I park, go to get something out of the hatch, It's locked! I have to go back to the driver's door to unlock or get the key, then back to the back to get my stuff. Must have happened at least six times in a four day rental. I guess you could get used to it, but not me. My last car had it and I disabled it the first day. I couldn't find the disable on the POS rental PT cruiser though.
