2020 Sierra 1500 Jerks After Full Stop

[adionline]

So, I just took my 2020 sierra 1500 (5.3) for the first oil change. Truck was driving without any issue prior, but after I got it back, I noticed the truck now jerks/jolts after completing a stop. Basically as soon as I make a complete stop, a quarter second later it, it now jerks/jolts. It can be felt in the cabin. Sensation wise, it sort of feels like someone running into the rear bumper at super low speed. The truck NEVER did this before the oil change. I plan on taking it back, but is there anyone in here who could maybe tell me how an oil change could cause the truck to do this? Or did they somehow mess something up?

Did they do any software updates that you know of?

Fuel sloshing? My 2500 does this when I have about a 3/4 tank of fuel and stop quick. Maybe something you never noticed before?
