both rear doors wont unlock or open from inside or out?

[Estroil 4.8is]

Hey guys, I haven't been on here in forever but, I just bought a 2004 4.8is in estroil blue. I'm having an issue with just the rear doors. Its happen twice in the last 2 days. Both rear doors won't unlock from the key fob or central lock button. The really weird thing is that I can't even open them from the inside out outside handles. My kids have to enter the dukes of hazard style, through the windows.

After I get in the X and drive in forward or reverse the central lock work and they are able to be opened?? Is this some weird safety option? Thanks in advance Rob
