How to increase reliability of the N63 engine in the M50i?
I'm currently debating between getting the x5 M50i or the X3M. As i plan to drive the car for 10-15 years, reliability is a concern for me. The X3M is based on the B58 engine which is said to be one of Bmw's more reliable engines. It has also served me well in my F30.
However, upon digging more into the N63 engine, it appears to have numerous problems regarding oil consumption, and problems that manifest with extra heat due to the hot Vee engine. A lot of people say that these issues plagued the earlier engines, but have been fixed with the TU3 variant of the n63. https://bimmerlife.com/2019/06/01/up...ption-lawsuit/ https://thelemonfirm.com/2019/12/03/...ed-n63-engine/ both those articles say that while the issue is present in past iterations of the engine, bmw has yet to fix the problem, and new lawsuits are being filed because of this issue. Are there any aftermarket solutions to solve this heat issue? While i'm not expecting toyota reliability from this car, I expect it not to require thousands a year to keep running. As of now I'm leaning towards the X3M unless anyone can convince me for the M50i. |

I keep my cars for a long time and have been struggling with the N63 decision as well. I ordered a M50i last week. After doing a lot of research, I found that a lot of changes and progress has been made. That said, life is short and for me the risk is worth the reward.

If i wanted a reliable car, i would buy a toyota or a honda. I want a bmw because of the driving experience/luxury. I do not expect perfect reliability from a bmw, but I expect it to be close in reliability to my B58 F30, which the N63TU3 M50i does not appear to be. I wanted to see if anyone had first-hand experience with the newer N63s to give some advice.

While numerous other issues have been reported with the G05 X5 here, I don't recall even one hint relating to engine issues. Now it's only been less than 2 years, but ... not even one report.
What I would be more worried for a long-keep car with modern BMWs and particularly the electronic/software "flagship" G05 is ... electronics/software. Both hardware and software on these cars is evolving quickly and even less than 2-year old cars still well in warranty are already being left behind. 10-15 years?

If i was interested in a reliable SUV i would get a toyota, but sometimes you want a vehicle that isn't point A -> point B while still being somewhat reliable.

If you are looking for reliability, the new generation MDX will be announced within the next month and will be available shortly thereafter. Other than regular maintenance, we have only had to pay about $200 for repairs in the 14 years we have owned our 2007. Extremely reliable, much less exciting to drive than the M50i. Reliable but not passion inspiring. I don't find myself looking for a reason to go for a drive in the MDX like I do with the Z06 and hope to with the M50i.
