That particular preliminary bulletin PIC6161 has been around for a while now
I've never really felt the need to post anything about here as its pretty much well established around here that while operating in extended range mode, occasionally the engine RPM of the ICE will "flare" (usually described as a sudden/brief RPM increase).
This occurs during certain transitional periods where the clutches and gear states (modes) within the Volt's transaxle are being reconfigured.
It does this in order to synchronize the speeds of rotational elements during the "shift" (clutch apply/release) whenever commanded, in order to maintain efficiency
and yes, (as often discussed) this is considered normal behavior
