It's just human nature, Chevy sold 529,755 Silverado's in 2014 and 600,544 in 2015, so even if 2% of those came to a website looking about how to fix something it would look overwhelming , even though 98% love their trucks. And then of course you have your Trolls!
Where I work we have contractors coming in every single day, many driving the new Silverados. I make it a point to ask them about their trucks. It's almost 100% approval, most say it's the best truck they have EVER owned !
