Achilles Heel of the G8x
Anybody have any ideas what it may be? We know with the E9x it seemed to be the rod bearings, and in F8x it was the crank hub closely followed by the TMIC leaking. Anybody have any ideas or already seeing the same issue across multiple G8x cars? Maybe we could even keep tabs on reoccurring issues early so BMW could possibly address it. Just curious!

IMO, the controversial front end , transmission (no DCT) , and weight. None of which personally bother me.

BMW record is not that bad actually, the B58 and N55 have been very reliable.

And BMW is not alone. We know all about them, as Bimmerphiles, but Porsche (generally recognized as one of the best engineering car companies) has had many different engine issues including bearings, seals, cylinder liners and fires, Mercedes are often regarded as money pits and of course Audi, which makes great cars that are in the shop almost as often as Maseratis. GM's premier performance car, the Z06 Corvette, often cannot survive a day at the track without overheating and going into limp-home mode, and if you spend a few hours on a Mustang forum you'll see that those guys have to spend thousands to rectify design issues that still exist on a nearly 60 year-old platform.

Where on earth do you get a $4k job from? I was the one that wrote the DIY for it, and it's a couple hours job, and the whole part replacement is $1k. Hardly a fortune when it comes to older M maintenance.

Probably the same issues as every other bmw dating back to 2006 when the first N54s rolled off the line, but not as bad as before as my modem BMWs are much more reliable compared to my older ones. High mileage will result in similar repairs I suspect.
- Valve cover cracking - Oil filter housing gasket leaking - Failed / leaky Injectors - Fuel pump - Water pump - Intercooler leaking - Oil cooler getting smashed when hitting debris on the road - Random sensors around the car failing due to age - Oil pan gasket / leaks
