Body problems of the 2006 Nissan Xterra

Rear passenger doors keep locking and won't open/unlock at all. Oem parts were used for actuator and other issues, however it has happened again. Very unsafe, as if they jam, we can't exit the vehicle and have to climb to the rear hatch or through the front seats. If there were an accident, it would be detrimental.

I purchased my 2006 Xterra on Feb 18th, 2006. Within 2 weeks I noticed it was leaking during rain showers when parked in my driveway. I took the vehicle to a dealer and they were unable to recreate the problem. I took the vehicle home and it leaked once again. I took it back to the dealer and they were unable to fix it. I took it home and it leaked again so I took it to a new dealer and they concluded, with the help of Nissan engineers, that a design flaw in the Xterra allows water to enter the vehicle when parked on an uphill incline. The water enters through the air vents under the cowling and drops onto the blower motor under the passenger side dashboard. The water then exits the blower motor through an electrical connector and onto the front passenger carpet. Nissan has offered no remedy for the problem.
