My '09 Journey started having a problem with the rear passenger door lock. It wouldn't unlock unless I opened the drivers door or pressed the unlock button. I check to be sure the child protect was disabled and it was. It progressed to where now, it will not unlock at all, unless you climb into the back seat and stretch over to manually unlock it. Also, sometimes it will not lock when you drive and sometimes it does. A new assembly is ordered and I will have it installed for about $320. I have also had to have the front passenger lock replaced a few years ago. I only have 64,000 miles on the car and am being told I need a new heater core because the passenger side is not putting out hot air, (Drivers side is fine) and whatever makes the air deflect from upper to lower is malfunctioning as well. I think these are know issues and Dodge isn't taking responsibility for their manufacture defects!
