Agreed.
OP : does the rear bow go up after it unlatches ?

Indicate the step your failure occurs :
1. turn 'D' handle and push up. Windows should go down and top should go up about 6" and stay.
2. push top down button, trunk should latch, rear bow should release ( pop ! )
3. rear bow should raise.
4. tonneau cover should unlatch,
5. tonneau cover should raise.
6. top should start going into well.
7. tonneau cover should close.
8. tonneau cover should latch and one beep should sound.

Look around real good for any hydraulic leaks, there are 7 hydraulic components :
1. bow latch
2. tonneau latch
3. one tonneau cylinder
4. 2 'main' cylinders
5. 2 rear bow clyinders.
check the level in the pump reservoir
