weird flutter and dash light going up small hill then went away

hey guys, not sure how to describe this aside from the title.. here's what happened..
driving down the road and had to turn around (forgot concert tickets rookie move), turned
down a side street into the driveway of a house that was at the corner of a hill..
backed out and started back toward the main road.. only about 40' but up this little pitch 25 degrees or so.. hit the gas and got this fluttering feel going on as well as dash light that showed vehicle with the skid marks.. did maybe twice quick then went away.. felt like i may
have thrown it into 4wd by mistake but that wasn't it..
whats up with that?? thanks

 

2017 off road btw

 

Traction control, must have gotten some slippage on one of the rear tires. Sounds normal.
