Official summary
CONVERTIBLE TOP WILL NOT COMPLETELY STOW: This Service Information Bulletin (Revision 3) replaces SI M54 03 17 dated May 2019. When attempting to stow the convertible top it does not compress into a fully locked position on the left side. This prevents the soft-top bow cover from moving forward into proper operating position as shown in video 54 01 17. Additionally a warning gong sounds and a Check Control Message "Roof not locked" appears. One or both can apply: An issue with the convertible top assembly gripper hook Improper adjustment of the convertible top storage spacer adjustment bolt Da
