I have the GM Service Bulletin 13-00-89-007 dated June 2013 and it states, in part, that " Depower the vehicle by removing the negative cable at the battery. This procedure must be followed or the steering column could be damaged." Is there an alternative such as pulling a fuse or two that manage the steering column components that could be damaged? Loss of battery power results in having to reset radio stations , maybe Bluetooth and possibly other items. Seems cumbersome since a quick disconnect will not work as the terminal is recessed and does not sit above the top of he battery.
