Let the left side seat back down to get access to the seat belt, and the the back won't latch back in the upright position. Have pried around with a screw driver trying to get the release button to pop back up but no luck. Any good solutions?

 

Common issue, release cable needs replacing. Depending on where in the world you are, it will be covered by your 3yr manufactures warranty.

 

Eventually, by playing with the releases in the cargo area, I was able to get that seat back button to pop up -- all is well. Was not aware it was a common problem -- thanks.
