For the sake of contradicting myself, I'm sure there are some exceptions, but I'd feel pretty safe betting money that MOST of these issues are driver related.

Also, I have a tough time accepting the claim that 88K miles are considered "high mileage" especially for a "high end" car.

OP - good luck with the repair(s). Pls keep us posted.

Car never been through the track nor have it been racing, baby it most of time talk to BMW NA but no help available

Replaced my bearings at 85k. Car is SC w/AA Stg 3 Gen 2 since 71k. Blackstone prior to SC install showed no signs of bearing material.

I don't run it hard while cold, change oil with Castrol 10w-60 every 5k, but I DO beat on it hard regularly. Changed the bearings @ 85K.

My shop almost stopped working on it because the bearings they were removing showed no signifigant signs of wear. Went ahead with the job anyway. At this point it's worth it to me just for the piece of mind.

Perhaps there is something to this idea that misuse in some cases is contributing to these failures. I by no means baby my car, but I also don't abuse it while cold, and make sure it has fresh oil every 5k.
