"Jerky" Driving

[texasguy]

I drove a 2004 Chevy 2500 4X4 for 15 years, so I have no experience with the newer models.  I recently bought a 2018 Silverado 1500 High Country, and I hate the driveability of it, so I'm wondering if this is just how Chevy trucks are now?  I don't want to personalize this truck that I don't even like driving due to the jerkiness.  Here's what it is doing, feel free to comment on any of the "issues".  I've read up some on the 8 speed transmission issues, but need to know if it is even worth fighting with the service Dept.  I've only got 11K miles.

• Slow take-offs are jerky
• Fast take-offs delayed - I know I can fix this one with a $200 module
• Coasting up to a light slows itself to the point I have to get back on the accelerator.  I don't know if this is the trans downshift or going from 8 to 4 cyclinders.
• The brakes brake harder than I am on the pedal.  I don't know if this is the "intelligent" brake assist, but I'm barely on the brakes approaching a light and it brakes hard enough to throw me forward. or is this downshift or change in # of cylinders.

It just annoys me that you can't have a smooth ride with this truck no matter how hard I try.

Any help or comments would be helpful.  I've got to decide to keep this truck if things are fixable, or get rid of it for something else.
