Warning Light, Temperature Indicator Question

Ok so, I've done some digging on this topic which has brought me here to ask some questions, but here's my series of events. Not sure what all is relevant, but here you go:

2004 Prius, 135,000 miles.

About a month ago, the blower motor stopped coming on all the time. A quick whack under the glove box fixed it when it didn't start. Then about a week after that, I felt like the AC wasn't really warming when needed. This may have been true earlier, but it hasn't been that cold around here, so I wouldn't have noticed, perhaps.

About a week ago, I start hearing what I might describe as a rattling kind of noise I had never heard before sometimes under hard acceleration. Not always. Didn't hear the noise tonight, for example. Of course, then, tonight, on the interstate, the warning light pops up for just long enough for the temperature indicator to flash up. It quickly disappeared, but in the remaining two minutes I was driving, it flashed up briefly twice more.

Now, in digging around on this topic, I've read about issues with the inverter coolant pump, and that there was a recall. How could I find some information on this recall? I don't remember ever having it changed, so I'm just curious what I might need to say to get that swapped out under a recall if appropriate.

Also, based on what I've said, does it seem likely that the issue is with that pump? It sure seems to fit the bill, but who knows. I'll be bringing the car in ASAP but I'd naturally like to be armed with as much information as possible.

Thanks!

 

Update: Brought the car in to the dealer, and they're saying its a different water pump, not the one subject to the recall-esque notice.
