2019 Silverado recent issue

[Aguilar2319]

So I was driving and all of a sudden I get a  “service parking brake” light and also a check engine light and a third one that I forgot. I pull over, turn the truck off and when I turned it back on all the lights were back off. 
 

I started driving again and it was accelerating fine but now every time I slow down to come to a stop, it jerks forward at around 3 mph then stops. Every time. I’ll start slowing down then once I’m almost to a complete stop, jerks forward again. 
 

it feels like it’s in the brakes but I’m not sure, this is a 2wd 
 

does anybody know what could possibly be going on? I have an appointment with the dealer on Monday but just wanted some insight. Thank you

Are you able to all OnStar to perform a diagnostic?

Whenever I've experienced a problem with my truck, the first thing I've done is hit that OnStar button and ask them to run a diagnostic test for trouble codes. If anything pops up they send me an email. This way, if the problem goes away after I shut off the truck I'll have documented proof to provide the dealership.
