Glow plug recall
I also have an 06 LBZ Silverado and I don't know of a glow plug recall. There is a recall to reprogram the glow plug controller. That recall was the only time my 06 has ever been to the dealer since it was new. You can take your truck to most auto parts stores and check the codes to find out which glow plugs are bad. Kennedy Diesel sells a good replacement glow plug much cheaper than the GM dealer. Changing a glow plug is a lot like changing a spark plug. You only need basic tools and skills.
Good luck
