Electronic slip noise while on slight incline

Rscently purchased 2017 TRD offroad. While on a small incline coming out of a parking lot the slip indicator flashed out for a second and heard what seemed like electronic slipping noise. Any ideas to check? Traction was not lost.

 

Welcome. It sounds like the traction control went off which is fairly normal. I get similar behavior with the slightest slip of the wheels...loose dirt/rocks. My 2012 Tacoma was ten times worse and would hop. The first time I ever experienced that was when I had my ATVs and trailer attached. It felt like my truck was having convulsions.

 

Nothing to check. This will happen sometimes...normal.

Mine does it sometimes in my driveway.
