“After putting the hardtop down and receiving the complete message, I then got another message saying 'retractable top not locked'- see owners manual. After reviewing the manual, I could not dismiss the warning or put the top back up. I have been getting this same message whether the top is up or down since purchasing the vehicle and it has been in the shop almost the entire 3 weeks I have owned it! The car was running and in park when the top was initially lowered and received the message the first time.”
