325Ci (Convertible Top Problems)

The automatic one-button power convertible top keeps getting stuck in the open position. We have taken it back to the dealer three times. They don't know how to fix it. It works at the dealer when we pick it up, then we take it home and in a day or two try to open it and it gets stuck again. Help!!

one more time its a lemon , bring it back in for a new one

replace the bowstraps on the top if its getting stuck on the convertible top lid.
