I plugged mine in for a few weeks after getting it. Worked as should, but after unplugging, the auto/start feature is still disabled. Has anyone ever seen that behavior? 2019 5.3L with 8 speed.

Anyone here tried the https://www.rangetechnology.com/products/afm-dfm_disabler/ yet? The stop/start thing really gets on my nerves as well. I've also heard of people just leaving their truck in tow/haul mode. My trailboss has the 'race' mode too but I've not tried it enough to see what it does with the autostop.

my 2019 LT Trailboss, does same thing, but I really notice after it hasn't been driven in a few days. I work from home, so I don't go out every day. But when I test drove the truck, it drove great... hahaha. But now it does the 'lunging' up to about 45-50 mph. But from the posts, looks like the dealer may not be any help.

First 'almost' new Chevy in a while, last one was a 2013 BlackDiamond LTZ Avalanche. Bought this 2019 with 8000 miles. No mods yet except for LineX bed liner. The step bars come already on it, and less than two months already showing signs of wear. LineX guys said they would spray them for 200 bucks if I ever decide to get them done.
