I think I'm having the same issue in my 2019 Silverado. First time it happened I had it towed to my local dealership, they had my truck for 4 days and told me nothing was wrong with it as they could not replicate it. They suggested I put it in 4 Low by mistake and that ran me about $200.00.
Now 2 weeks later it happened again, I got it on video, but of course the next day it doesn't happen. Is it worth going back to the same dealer? I want to because at this point I paid them to tell me I'm crazy but fear it will not replicate while they have it and I'll be out more $$.
