Very much so, a well known fault.

Pleanty people made plenty money replacing them over the years.

Bit like @Jaws with Bird CCTs and generators...

I had a 996 C4S a few years ago. Paragon, an independent Porsche specialist, are near to my home and I know the service manager well as his wife is the daughter of a friend of ours. I asked him about the IMS issue and his view is that it's over hyped, he said that he had seen only a handful of cars which had the problem. Even a handful is too much especially for a quality brand, but it reassured me. And I never had a problem with my car.
There is another potential weakness with that engine which is bore scoring, but that is largely thought to be due to a failure to warm up properly, ie not letting it idle for long when cold and not revving it hard till properly warm.

My son had a 911. He took out the maintenance plan.
Bore scoring was discovered.
He reckons it cost several thousand to rebuild the engine. Few other things turned up too. He seems to have got his money's worth out of the plan.
