I'm speaking from a US point of view. To my knowledge there are no 240 watt USB-C chargers in existence.
There are a handful that claim 240 watts but upon closer inspection only provide a max of ~100 watts per port.
There are cables sold with a 240 watt rating but no actual chargers.
Voluntary recalls are actually more common than ordered recalls. Manufacturers usually don't wait for the NHTSA to get involved.
What makes it a recall is that either the manufacturer or the NHTSA determine that there's a safety defect or that the vehicle doesn't confirm to the Federal Motor Vehicle Safety Standard.
So I believe the terminology is required by the NHTSA if it fits the above definition regardless of how the issue is addressed.
Of course this is for the US and this is a recall in China but I'm assuming similar legal requirements are involved.
