Why shouldn't the owners drive the cars that they paid for just because of your design or manufacturing flaws? I say the owners should ignore the warning and keep driving their $100k super sedan/coupe and if issues come up and the engine is severely damaged then its BMW's responsibility to replace them..........it's within their powertrain warranty isn't it?

Which goes to show that sometimes you can't have your cake and eat it as well. There are some that deride Lexus for not going Forced Induction but the higher-ups at Lexus know full well the reliability trade-offs for turbo-ed/supercharged cars.
If/when Lexus comes out with a turbo/super-charged engine, you can bet they'll have tested the heck out of that engine and that it'll be as reliable and painless to own as a NA engine.

The N54 engine itself is actually very reliable, most auto enthusiasts are comparing it in strength to the Toyota 2JZ. The main issue has been FUEL pumps and that specifically because it is a DI motor. This issue has also plagued other brands (though not as notably because BMW sells more turbocharged cars) because the supplier of the part made bad parts (which has now been remedied). One can criticize BMW's handling of the issue (which was handled VERY poorly imo - but anyone who had a warranty was covered unless they had a car with a lot of mods).I'm not aware of too many N54-based cars have oil pump problems. Perhaps you'd like to elaborate?

So the problem isn't because it's a turbo-charged engine per se.
It's because it's a engine made by BMW.
Got it....
Joking aside. Lexus GR-FSE (with direct injection)came out in 2006 and has been rock solid. Again I ask : what's BMW's excuse? And don't say that it's because BMW sells so many DI engines. Lexus has been selling DI engines since 2006 and I'm betting the number of Toyota/Lexus DI engines out in the world far outnumber BMW DI engines, yet one has far fewer instances of DI-related problems despite selling in larger numbers.

24 M5s delivered on 09/01/12 ED. I feel sorry for them.

Sigh...this is the only reason it has kept me away from potentially owning some of BMW's finest of the past & makes me appriciate Lexus reliability much more. Looks like the only ///M I like that is actually quite trouble free is the E9x M3. But we'll see how well those DCT's hold up in the long run.
The problem comes in when you want to eat all the cakes at once, and do it right away. When you want a high power turbocharged engine and want to keep it efficient - you need to have high compression and very efficient injection system. This where you will run into reliability issues, especially if you rush it to the market and have BMW's mentality of "you suckers will buy anything". It gets even worse with diesels - I'd love to see maintenance and repair bills on these fancy "bluetecs" in 10 years.
This is why Lexus isn't rushing an engine like that to the market. They don't settle for half *** unreliable designs. Knowing Lexus, they will design it until its bulletproof and only then launch it.

This shouldn't be a surprise to anyone. I wouldn't touch any of BMW's new turbo models, even leased. BMW has had all kinds of problems for years now with their turbo vehicles. Even with leasing, you'd have the constant hassle of having cars like these in the shop often.
Even if someone gave me a new M5, I would just sell it and buy something else like a Panamera or the coming GS F.
