You can add another car to the list.
2010 E92 50K miles (80K KM)
unmodified
full service history
never tracked - easy highway miles
number 1 main bearing failed resulting in catastrophic engine failure (complete loss) on highway

Sorry to hear Feisty. Where are you located? (can't see sign from phone).

Let us know if further diagnosis shows rod bearing issues. Not so many main bearing failures have been reported.

Sounds dangerous!
Sorry to hear this.
What were your OCIs?

[MrFeisty]

Yes it was a rod bearing.
And yes it was frighting.
Occurred on a wet single lane road in poor weather.
I was lucky to avoid an accident when vehicles following me were caught unawares by my unexpected deceleration. The was little opportunity to pull over to the side of the road with safety due to the conditions.
Lost power steering and power brakes which made the car more difficult to control.

Can you help the community and take 5 minutes to file a complaint with NHTSA since it happened while you were driving?

So I have been trying to read up on this issue in order to do preventative maintenance on my 08 e92. It seems that in 2013 the best option was to go with treated bearings due to the clearance being equal to OEM.

Is there now a coated option that has similar clearance or better than OEM? Is this considered preferred to WPC treated bearings?

I plan on using a blackstone report to determine when I really need to do it, but I am seeing in some threads (without sources) that oil analysis does not always show the issue?

There is an increased clearance bearing now, though we won't really know if it's a solution or not until a large number of people have been driving on them for a couple years.

How high is the percent of bearing failures from owners who track their cars?

[pbonsalb]

Unfortunately, no one can say that only tracked cars fail. And one guy who is rabidly against bearing changes tracks his car and has experienced no issues. And other people who have never tracked their cars have had bearing failures.

Wow, thats crazy.

So what is the chance of them failing up to now? 2%?

Well my 13' crapped out. 3100 miles on the clock died in slow traffic. new motor. bone stock.

Well, at least you should be covered under warranty!

Better now than next year.

Very true! but what happens next year if it happens in another 3k miles!!

Then you should be covered under the two years parts/labor warranty

Two years wow that's pretty good I thought it was only one year

Wow that sucks. Do they know what happened? Seems that for every car we see with 150k + miles we see one that dies young. BMW should be ashamed.

There is conflicting information from the manufacturer of the OEM bearings bebearings (https://www.bebearings.com/) saying the older 2008-2010 bearings are more reliable than the 2013s.

"Newer factory bearings (2010.5 and later) are made from tin-aluminum, not lead-copper. Tin-aluminum bearings are 4-times harder on the surface than lead-copper bearings. This extra hardness shows signs of doing more damage to motors as there seems to be more bearing failures with 2010.5 and later vehicles. Tin-aluminum bearings also don't show the same signs of premature wear in Blackstone oil analysis due to lack of lead and copper."

Very useful information thank you. I am curious to know if there were any pre-lci failures that were showing healthy blackstone reports.

If 100% of the time the wear will show a few oil changes away from failure I will wait to replace mine.

Wow is right!
What did the dealer say? BMW NA?
I assume you did the 1200 mi break in service, so the oil had ~2000 mi on it....
DCT or MT?
Any serious revs prior?
Were there any strange sounds or telltale symptoms or just abrupt?
