I'm new to this site, stumbled upon it after months of frustration with my 2015 Tahoe. Main issue is the creaking/rattling from the dash and the most annoying metal on metal rattle coming from the seat belt housing right at ear level. I've had my Tahoe in the shop now for two weeks. They did replace the steering column which eliminated a bit of the dash noise, but not all of it. Anyone with a similar experience or fix they know of??
