E92 M3 Rod Bearing issues

[smokey12]

I own a 2011 E92 M3 with 14K miles. I have just been sent a YouTube review - link below -https://youtu.be/aWxdaEJMTwU which highlights a particular and potentially expensive issue for the V8 after about 40K miles suggesting that the rod bearings that are fitted are not up to the job and should be replaced to ensure the engine does not fail.
I apologise if this topic has been discussed on the Forum already but with nearly 500 pages on the Forum I thought it would be easier/quicker simply to post this to seek a view

If you look on m3 cutters there is a large thread on it.

Yes some suffer with the issue and the engine is scrap pretty much if it happens.

Id change them for peace of mind.

From what I've read is its mostly a US issue made worse with poorer quality fuel.

Not many cases in the UK.

The problem mainly affects USA cars.
I've only come across 3 rod bearing failures in the UK...which makes for a very low risk indeed.
Take out a BMW extended warranty for complete peace of mind.
Edit: Heh, beat me to it.

Make that 4!

I picked mine up this morning after a new engine under BMW approved used warranty.

Car is 2012 and the engine scrapped itself after 29k miles, due to a rod bearing failure.

Did you notice any symptoms before the failure - either at the time, or with hindsight?

Nothing especially noticeable although thinking back, it may have had the ticking noise which I have read about that some people attribute to this problem.

There still seems to be some ticking with the new engine so i'm not 100% convinced this was a sign.

In terms of performance it was as normal up until everything just shut down and after that the engine was totally dead, wouldn't do anything when you pressed the starter button.

Did you stick to the same brand of fuel? Which one?

Thanks

Mainly Shell although with a few tanks of supermarket fuel mixed in. Always super unleaded though. Only had the car since January this year so could have been run on something else prior to that.

And the service history was OK (including the 1200 mile service)? I guess that this must have been OK for BMW to cover the repair under warranty.

A bit worrying, as I understood that cars from 2010 onwards had rod bearings to a different spec, in order to address these failures.

So the S65 has the same problem as the S54?

And s85

A handful of cars out of 8112 UK S65 M3s is nothing to get too excited about.

Comedy gold.

I think a warranty might be more appropriate risk mitigation in this scenario, even then you could argue it's over kill given the probability.
