2006 Nissan Quest 3.5 SE 4dr Minivan (3.5L 6cyl 5A)
We bought a demo model of the Quest which was fully loaded (DVD, navigation, wireless headphones, leather, power everything, etc..) It's back in the shop for the FOURTH time as the rear lift gate arm keep breaking off. Now Nissan has to replace the entire rear lift gate and arm (the bolt the lift arm connects to is integrated into the entire door and is stripped). The dealer tried repairing it 3 times previously, replaced the lift arm twice, and every time it breaks of within a matter of weeks. The quality of the components is very, very bad. We had the cover on a power outlet break off, same with a handle on the middle seat. Now we're scared because it just went beyond 36,000mi.
Navigation system, DVD system, rear camera, power doors/liftgate (when they're not broken).
Design repairability into the vehicle - this is not well designed, and repairs are major even when a small piece breaks.
