I've put over 150k miles on all my bmws, they are not maintenance free but not maintenance intensive either.
Plastics may have blown up back in the stone age of e36s and e46s, but not anymore.
They absolutely "will not" self destruct at 60k miles but they also should not start to slowly fall apart after 75-85k miles.
Ours was flawless till 75-80k miles and then it began to nickle and dime us with constant annoying small issues along with some major ones.
Ive been driving and wrenching on BMW's for almost 20 years, These latest models are not built to last, Once warranty/lease is up its a roll of the dice.
It got to the point where my wife did not trust taking it when going on longer trips with our kids.
Our last 2018 G01 X3 had the following go wrong at 80k miles or so :
- Oil Filter Housing Cracked
- Main coolant line to block under intake manifold cracked
- Radiator Leaking
- Turbo coolant return line leaking.
We replaced all the above plus every hose under the intake manifold while we were in there for $4500 (mind you I typically DIY everything, this was a bit much ).
I wasn't waiting around for the Heater Control Valve and Water pump to start leaking next and cost me another couple grand, All for a car with less than 100k miles which is pretty ridiculous..
You need to do some more searching on here to see how many "low coolant", "Another Coolant Leak" threads there are, how is this acceptable in 2025? These are basic things.
You are in absolute denial if you think the modern BMW's are not subject to insane amounts of plastic degradation and coolant leaks that other mfr's never have.
My E90 was semi flawless till 100k, my F30 great till 110k, G01 started Puking its guts at 80k...
