Last week, I wanted to show my daughter what 7k rpm sounds like, so at a stop light I started to rev it out and hit a "wall" at around 4k. It just stopped revving. A minute later at another light, everything was back to normal. A couple of days later, as I was merging onto the highway in third gear, same thing -- it momentarily stopped revving at around 4k. In both cases, the engine was already warmed up.

If this happens again, I'll take it to the dealer for diagnostics, but has anyone else experienced this? It's bizarre.

The third gear highway merger scenario sounds normal, incline/decline/computer/traction control factors into the rev limit. Turn off traction control and see how the car behaves. With no codes it's hard to know whats going on.

I've learned to turn off the traction control when aggressively merging from a stop, but it's never intervened in rolling acceleration like this. The phenomenon does feel similar though, so who knows?
