 Gas cap broken, it will not shut tight and will not open with pull switch inside the car.  Trunk will not open by pull tab inside car or remote button.  Will only open by key.  Rear bumper loose and hanging on passenger side.  Wheel bearings were replaced on driver rear within 6 months of purchase. Rear passenger side now need replaced.  Difficult to start at times.  I will NOT buy another Nissan Sentra.  No freaking way.
