If it was anything other than the crank hub then I would agree that this is a 'pay to play' issue. But the crank hub really is a poor design and should be offered blanket fixes imo.

Be careful posting things like this on a public forum. Any dealer you take it to can easily scan this forum for threads like this and then use it to deny your warranty claim. There is already enough info here to narrow it down to you.

On a side note this is why I don't want mod my car for anything other than aesthetics.

I'd do the same, plead plausible deniability. I disagree that this is fraud, because a modification does not always necessarily cause the failure , plenty of failures on stock cars. No real scientific data on causes of failure. Is it fraud that BMW built a car that costs a small fortune, marketed as the ultimate driving machine and hasn't addressed a known failure point?

I don't think it is fraud that he is trying to get it fixed under warranty. This is a known issue and it has happened to stock tuned cars. BMW knows there is an issue with the crank hub but they are doing nothing about it. So who is the fraud here?

Don't feel bad about it OP. This is a defect that happens on stock cars. BMW had many years to fix, but instead they continually sell a 85k performance sedan where half the owners are afraid to put the pedal down for fear of breaking it.

Warrant that bish. Cost concerns is the only thing that will make BMW fess up to the issue and resolve it.

This reminds of the E46 subframe issue and we know what happened with that.

Agreed. Everyone is scared to modify the car, because of a know weakness breaking on stock cars.

The problem is that it was only good for a limited time. So thinking big corporate and the actual percentage that this would apply to.

Factory tune = Power within motor tolerances. Installing a tune to get more power out of the motor exceeds it.

I disagree that the factory tune is within the motor tolerances. The factory tune was also spinning the crank hub out of place. Installing a tune only amplifies that possibility of this happening. Everyone drives differently and as such some spins on stock cars and most spins on tuned cars.

Factors like using the kickdown on the DCT extensively including the use of the kickdown during manual mode to drop it to the lowest gear introduces a huge rush of torque that puts a lot of strain on the crankhub causing it to spin apparently. This should not be happening as the crankhub is supposed to be keyed/pinned to the crankshaft. I myself am surprised BMW managed to overlook such an important factor on the S55 but some have mentioned the reason of fact that it is a failsafe from the engine grenading when the hub spins. Either way, it is a shitty fail safe system and a cost cutting measure to not have keyed/pinned the crankhub in the first place.

This happens both on stock and tuned cars with the excepetion that you do not hear much on stock cars happening because they probably are not even on this forum or the sample pool size of those having bone stock cars on this forum is low.

I am not substantiating that BMW should pay for cars modified nor encourage a culture that warranty should be fraudulently be claimed but this problem is an inherent weakness in the engine that is happening even on stock cars and BMW warrants them. If this is not happening on stock cars at all, I think we can agree that the factory tune power is within motor tolerances then. And this part of the sub-forum Engine / Drivetrain / Exhaust / Bolt-ons / Tuning would probably be empty.

I have a question;

What parts must change after this failure for example?
Full engine? Or just some parts? Any idea?

So are the tolerance measured in which tune, stock, ZCP, CS or in GTS? Because I think there are instances where stock tune does suffer from a spun hub. So under your statement, GTS cars are just a ticking time bombs.

Why should I be afraid to hammer the throttle for fear of a spun crank hub if it's covered under warranty. If I make no mods to the car, and this is obviously a weakness, BMW will pay to fix it if I have a problem. That's why I buy cars with a factory warranty.

I double track my CS, 40 days this season, and make sure to keep the engine and exhaust stock so that if I have a problem BMW will cover it

I live in exactly zero fear of problems. That's why it's under warranty and that's why I don't make 550whp. The car is plenty fast at the track without modding power.

Agreed, it happens to both factory and aftermarket tune M3/M4's. I was merely implying that an aftermarket malware tune exacerbates it. That the ratio between factory and molested motors with engine failure is lopsided.
