These are he same symptoms I’ve been having for months and have had no luck figuring it out. Typically the symptoms happen when the airbag symbol lights up on dash. I’ve read it could be different things, from the airbag module to the SAS to the clockspring to the ignition switch. I haven’t figured it out and the problems are more consistent now, specially on a really hot day. Even the top doesn’t latch/unlatch when airbag light is on. Sometimes the trunk won’t open either. It’s not the GM5, Scott checked it out so that’s ruled out. Let me know if you find something and I’ll do the same. I’m about to replace my ignition switch again, only because it’s cheap and the last time I replaced it, it was with a used one I bought. Perhaps that ruined things and now is giving me these symptoms. Here’s an article from pelican where it talks about it;
